The total number of people who voted altogether is 3160.
if cary's governor received 790 votes and grantsville's governor received three times as many votes, we can calculate the total number of votes cast by adding the votes received by both governors.
let's denote the number of votes received by grantsville's governor as g. since grantsville's governor received three times as many votes as cary's governor, we can express this as:
g = 3 * 790
calculating this:
g = 2370
so, grantsville's governor received 2370 votes.
to find the total number of votes, we add the votes received by both governors:
total votes = votes for cary's governor + votes for grantsville's governor
total votes = 790 + 2370
total votes = 3160

Would the function describing the relationship between the denomination of U.s. currency and the weight of one million dollars be a discrete function or a continuous function
The relationship between the denomination of U.S. currency and the weight of one million dollars can be categorized as a discrete function. A discrete function is one where the input values are distinct and separate, with no intermediate values between them.
In the context of U.S. currency, the denominations are well-defined and specific, such as $1, $5, $10, $20, and so on. Each denomination corresponds to a specific weight when considering one million dollars.
For example, if we consider $1 bills, the weight of one million dollars would be significantly different from the weight of $5 bills or $10 bills. The weight is directly associated with the discrete values of the denominations.
On the other hand, a continuous function would involve a relationship where the input values vary continuously within a range. In this case, there is no continuous range of values for the denomination of U.S. currency. Each denomination has a specific weight, and there are no intermediate values between them.
Therefore, the relationship between the denomination of U.S. currency and the weight of one million dollars can be categorized as a discrete function, where the specific denominations correspond to distinct and separate weights.

Sometimes Kevin has kittens. Each kitten has

as much cat food as a full-grown cat. How many kittens can Kevin feed with the 3.51 pounds?
We need to consider that each kitten is fed half as much as a full-grown cat. Let's assume the amount of cat food needed for a full-grown cat is x pounds. In that case, each kitten would require x/2 pounds of cat food.
If Kevin has y kittens, the total amount of cat food required for all the kittens would be y * (x/2) pounds. Since we know that Kevin has 3.51 pounds of cat food available, we can set up the equation:
3.51 = y * (x/2)
To find the number of kittens, we need to know the specific amount of cat food needed for a full-grown cat (x). Without that information, we cannot determine the exact number of kittens Kevin can feed.
However, we can provide a general equation for the relationship between the number of kittens and the amount of cat food available, given the assumption of each kitten needing half the amount of a full-grown cat.

On a nut and bolt production line, all the nuts weighed the same and all the bolts weighed the same. An order of 50 nuts and 60 bolts weighed 10.6kg. An order of 40 nuts and 30 bolts weighed 6.5kg. How much would 60 nuts and 50 bolts weigh ?
The weight of 60 nuts and 50 bolts would be 9.25 kg.
We have to given that,
An order of 50 nuts and 60 bolts weighed 10.6kg.
And, An order of 40 nuts and 30 bolts weighed 6.5kg.
Let us assume that,
Weight of one nut = x
And, Weight of one bolt = y
Hence, We get;
50x + 60y = 10.6 .. (i)
And, 40x + 30y = 6.5 .. (ii)
We want to find the weight of 60 nuts and 50 bolts, which we can denote as:
60x + 50y = ?
To solve for this, we can use the two equations we have to eliminate one of the variables, either x or y.
Let's start by eliminating x:
Multiply equation 1 by 4 and equation 2 by 5, to get:
200x + 240y = 42.4 (equation 3)
200x + 150y = 32.5 (equation 4)
Subtract equation 4 from equation 3:
90y = 9.9
y = 0.11
Now we can substitute y = 0.11 into equation 2 to solve for x:
40x + 30(0.11) = 6.5
40x = 2.5 x = 0.0625
Therefore, the weight of 60 nuts and 50 bolts would be:
60(0.0625) + 50(0.11) = 3.75 + 5.5 = 9.25 kg
So 60 nuts and 50 bolts would weigh 9.25 kg.

When Lorretta was 18 years old, she deposited $100 into a 20-year certificate of deposit (CD) account that earns interest at a better rate than her standard savings account. She must leave the money in the account for 20 years, without making any withdrawals or deposits. Six years later, she had $132 in the account. Write an equation that will represent this situation, and use the equation to determine how much money.
this has to be in y=ab^x form and we have to solve using logarithm rules but I wasn't there for that lesson
Therefore, the amount of money in the CD after 6 years is $200.76.
Given that Loretta was 18 years old when she deposited $100 into a 20-year certificate of deposit (CD) account that earns interest at a better rate than her standard savings account and she must leave the money in the account for 20 years, without making any withdrawals or deposits.
Six years later, she had $132 in the account.The formula for the growth of money at a compounded rate is given by
y =[tex]a (1 + r/n)^_(nt)[/tex]
Where
y = the amount of money at the end of the period.
a = the initial amount of money.
r = the annual interest rate in decimal form.
n = the number of times compounded per year.
t = the number of years.
The initial deposit was $100, and the total amount after 20 years would be $132. So, we have
$132 =[tex]$100(1 + r/n)^_(nt)[/tex]
Taking the natural logarithm of both sides,ln 132
= [tex]ln(100) + ln(1 + r/n)^{(nt)}ln 132 - ln 100[/tex]
= nt ln (1 + r/n)ln (132/100)
= nt ln (1 + r/n)ln (1.32)
= nt ln (1 + r/n)ln (1.32)
= t ln (1 + r/n)ln (1 + r/n)
= ln (1.32)ln (1 + r/n)
= 0.2877
Since the number of times compounded per year is not given, it can be assumed that it is compounded annually.i.e., n = 1
Therefore,ln (1 + r/1)
= 0.2877ln (1 + r)
= 0.2877r
= [tex]e^{(0.2877)} - 1r[/tex]
= 0.3338
So, the rate of interest is 33.38%.
Therefore, the equation for the amount of money in the CD after t years is
y = [tex]100(1 + 0.3338)^t[/tex]
Thus, the amount of money at the end of 6 years is
y = [tex]100(1 + 0.3338)^6[/tex]

When calculating the effective rate of a loan, which statement or statements must be true if n is equal to 1? I. The nominal rate equals the effective rate. II. The length of the loan is exactly one year. III. The interest is compounded annually. A. I and III b. II and III c. I only d. III only Please select the best answer from the choices provided A B C D.
The statement that must be true when calculating the effective rate of a loan with n = 1 is: III. The interest is compounded annually. Therefore, the answer is d. III only.
When n equals 1, it means that the interest is compounded once per year. In this case, the effective rate of the loan is equal to the nominal rate since there are no additional compounding periods within the year.
This is because when n equals 1, there is no need to consider the length of the loan (statement II) since it is already implied that the loan is for one year.
However, statement I, which states that the nominal rate equals the effective rate, may not necessarily be true for loans with other values of n. Hence, only statement III is required to be true when n equals 1 to calculate the effective rate of a loan.

What are the x-intercepts for the function f(x) = x2 2x – 15?.
The x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.
To find the x-intercepts, we set the function equal to zero and solve for x. In this case, we have the equation:
x^2 + 2x - 15 = 0
To factor this quadratic equation, we look for two numbers that multiply to -15 and add up to 2. The numbers that satisfy this condition are -5 and 3.
Therefore, the factored form of the equation is:
(x - 3)(x + 5) = 0
Setting each factor equal to zero, we find the x-intercepts:
x - 3 = 0 --> x = 3
x + 5 = 0 --> x = -5
Hence, the x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.

The shadow of a building is 32 m long, and the distance from the top of the building to the shadow is 34 m. We need to find the height of the building, rounded to the nearest tenth.
Let's consider the situation as a right triangle formed by the building, its shadow, and the distance from the top of the building to the shadow. The height of the building corresponds to one of the legs of this triangle.
Using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides, we can set up the equation:
height^2 + shadow^2 = distance^2.
Plugging in the values, we have:
height^2 + 32^2 = 34^2.
Simplifying:
height^2 + 1024 = 1156.
Subtracting 1024 from both sides:
height^2 = 132.
To find the height, we take the square root of both sides:
height ≈ √132 ≈ 11.5.
Therefore, the height of the building is approximately 11.5 meters when rounded to the nearest tenth.

The probability of not rolling a 3 on the next roll, given that the first two rolls resulted in 2 threes, is (5/6).
Since the first two rolls already resulted in 2 threes, we are left with only one more roll. A fair die has 6 possible outcomes, and since we already know that the first two rolls were threes, we can consider those outcomes as fixed. Therefore, on the third roll, the only remaining possible outcomes are the numbers 1, 2, 4, 5, and 6. Out of these 5 remaining outcomes, only 1 of them is not a 3. Thus, the probability of not rolling a 3 on the next roll is 1 out of 5, which can be expressed as a fraction as 1/5. Simplifying this fraction further, we get 1/5 = 1/6. Therefore, the correct answer is (5/6).
Since the first two rolls resulted in 2 threes, out of the remaining 5 possible outcomes on the third roll, only 1 of them is not a 3. Thus, the probability of not rolling a 3 on the next roll is 1/5 or 1/6, which is equivalent to (5/6).

Josephine made an error in Step 1 of solving the quadratic equation (2+6)^2 = 49. The mistake occurred when she took the square root of both sides and incorrectly simplified the square root of 49 as V49.
The correct simplification should be 7. The error in Step 1 led to subsequent incorrect steps and an incorrect final answer.
Josephine's error can be identified in Step 1, where she attempted to take the square root of both sides of the equation. The square root of (2+6)^2 is correctly simplified as |2+6|, which equals 8. However, Josephine incorrectly wrote it as V(2+6)^2 or V49.
The square root of 49 is actually 7, not V49. This mistake carried forward into Step 2, where Josephine incorrectly equated V(2+6)^2 to 7, resulting in the equation x + 6 = 7. Consequently, the subsequent steps (Step 3 and Step 4) were performed based on this incorrect equation, leading to an incorrect solution of x = 1.
Therefore, Josephine's error occurred in Step 1 of the solution process for the quadratic equation.

The swimming pool is open when the high temperature is higher than 20 c. Lainey tried to swim on Monday and Thursday (which was 3 days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was 30 c.C30, degrees, start a text, C, end text on Monday, but decreased at a constant rate in the next 3 days.
Answer: Let's assume the high temperature on Monday is represented by C30 (30 degrees Celsius). Since the pool is open when the high temperature is higher than 20 degrees Celsius, the pool was open on Monday.
However, over the next three days, the high temperature decreased at a constant rate. Let's denote the rate of decrease as "r" (in degrees Celsius per day).
Since the high temperature on Monday was C30, we can calculate the high temperature on Thursday by subtracting the decrease in temperature over three days:
High temperature on Thursday = C30 - 3r
We know that the pool was closed on Thursday, so the high temperature on Thursday must have been lower than or equal to 20 degrees Celsius.
Therefore, we can set up the inequality:
C30 - 3r ≤ 20
Now, we can solve this inequality to find the range of values for the rate of decrease (r) that would satisfy the condition:
C30 - 3r ≤ 20
Substituting C30 = 30, we have:
30 - 3r ≤ 20
Subtracting 30 from both sides:
-3r ≤ -10
Dividing by -3 (and reversing the inequality since we are dividing by a negative number):
r ≥ 10/3
Therefore, for the pool to be closed on Thursday, the rate of decrease in temperature (r) must be greater than or equal to 10/3 degrees Celsius per day.
The polynomial equation U(t)=2t4+3t3+48t2+75t−50 has two real factors of (2t−1) and (t+2). Select the two complex factors
The two complex factors of the polynomial equation U(t) are derived from the remaining quadratic expression 2t² - 3t + 19.
The given polynomial equation U(t) = 2t^4 + 3t³ + 48t² + 75t - 50 has two real factors: (2t - 1) and (t + 2). The two complex factors can be determined by dividing the polynomial by these real factors and finding the remaining quadratic expression.
First, let's perform long division using the factor (2t - 1):
______________________
(2t - 1) | 2t^4 + 3t³ + 48t² + 75t - 50
The division process gives us a quotient of 2t³ + 7t² + 41t + 25 and a remainder of 0. Now, we can factorize the quotient expression: 2t³ + 7t² + 41t + 25.
Next, let's perform long division using the factor (t + 2):
________________________
(t + 2) | 2t³ + 7t² + 41t + 25
The division process gives us a quotient of 2t² - 3t + 19 and a remainder of 0. Therefore, the remaining quadratic expression 2t² - 3t + 19 does not factor further with real numbers, indicating that the two complex factors are derived from it.

Tom’s house is 65 miles from the beach. A map uses a scale factor of ½ inch : 3 miles. Approximately how far is Tom’s house from the beach on the map?
Tom's house is approximately 1.08 inches away from the beach on the map. Tom's house is approximately 1.08 inches away from the beach on the map.
Let x represent the distance on the map. We can set up the proportion as follows:
½ inch / 3 miles = x inches / 65 miles
Cross-multiplying, we get:
3 miles * x inches = ½ inch * 65 miles
Simplifying, we find:
3x = 32.5
Dividing both sides by 3, we get:
x = 10.83 inches
Rounding to the nearest hundredth, Tom's house is approximately 1.08 inches away from the beach on the map. This means that on the map, the distance between Tom's house and the beach would be represented by a little over one inch.

Tengo 2080 cancionesCada canción dura 3 minutosEn total cuantas horas son?
If you have 2080 songs and each song lasts for 3 minutes, the total duration would be 6240 minutes, which is equivalent to 104 hours.
To calculate the total duration of the songs, we need to multiply the number of songs by the duration of each song. In this case, multiplying 2080 songs by 3 minutes per song gives us a total of 6240 minutes. To convert minutes to hours, we divide the total minutes by 60, as there are 60 minutes in an hour. So, 6240 minutes divided by 60 equals 104 hours. Therefore, you would have a total of 104 hours of music with 2080 songs, assuming each song lasts for 3 minutes.

Shape C, a complicated shape, needs to be divided into simpler shapes in order to calculate its area. These simpler shapes can be measured to determine their respective areas using applicable formulas.
To calculate the area of shape C, which is not a regular shape, we need to split it into simpler shapes. By dividing shape C into smaller, well-defined shapes, we can apply the appropriate formulas to calculate their areas and then sum them up to find the total area of shape C.
In order to accomplish this, we need to identify the simpler shapes into which shape C has been divided and measure their sides. These simpler shapes could be rectangles, triangles, or other regular polygons with known formulas for calculating their areas.
Once we have determined the measurements of the sides of these simpler shapes, we can apply the corresponding area formulas. For example, the area of a rectangle can be calculated by multiplying its length and width, while the area of a triangle can be found by using the formula 1/2 * base * height.
By finding the areas of these simpler shapes and summing them together, we can determine the total area of shape C. This method allows us to calculate the area of a complicated shape by breaking it down into smaller, more manageable components.

How much time should be budgeted for sick leave if the budgeted amount should be exceeded with a probability of only 10%
The budgeted amount for sick leave, with a 10% probability of exceeding it, is approximately 74.4 hours.
To determine the amount of time that should be budgeted for sick leave if the budgeted amount should be exceeded with a probability of only 10%, we need to find the z-score corresponding to a cumulative probability of 0.10 from the standard normal distribution table.
Using the z-score formula, the z-score corresponding to a cumulative probability of 0.10 is approximately -1.28.
To calculate the budgeted amount, we can use the formula:
Budgeted amount = Mean + (z * Standard Deviation)
Budgeted amount = 100 + (-1.28 * 20)
Budgeted amount = 100 - 25.6
Therefore, the budgeted amount for sick leave, considering a 10% probability of exceeding it, would be approximately 74.4 hours.
