How much money is pictured below?

The rate of interest in one account whose investment is $2300 will be 3.21%.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Aniyah puts $2300 in one record and $1400 in a record paying 4 % higher interest. Toward the finish of one year, she had procured $130 in interest.

Let 'x' be the interest. Then the equation is given as,

(2300 × x × 1)/100 + (1400 × 4 × 1) / 100 = 130

Simplify the equation, then we have

23x + 56 = 130

23x = 74

x = 3.21%

The pace of revenue in one record whose speculation is $2300 will be 3.21%.

In this case, the critical region will be in the right tail.

To answer this question, you need to conduct a hypothesis test to determine whether the mean amount of paint in 1-gallon cans from this manufacturer is significantly different from 1 gallon. The null hypothesis for this test is that the mean amount of paint in 1-gallon cans from this manufacturer is equal to 1 gallon, and the alternative hypothesis is that it is greater than 1 gallon.

To determine the critical region(s) for this test, you need to decide on the significance level, which is given as 0.05. This means that you will reject the null hypothesis if the test statistic falls in the critical region with a probability of less than 0.05.

In this case, since the alternative hypothesis is that the mean amount of paint in 1-gallon cans is greater than 1 gallon, the critical region will be in the right tail.

The length of BC is approximately 5.72 miles and the length of AC is approximately 12.67 miles.

Let's represent the length of the side opposite angle A "BC" and the length of the side adjacent to angle A "AC". We can then use the sine function to find BC:

sin(A) = BC / AC

Substituting the given values, we get:

sin(24°) = BC / 14

We can use a calculator or look up the value of sin(24°) to get:

sin(24°) ≈ 0.406

Solving for BC, we get:

BC = 14 * sin(24°) ≈ 5.72

To find AC, we can use the cosine function:

cos(A) = AC / AC

Substituting the given values, we get:

cos(24°) = AC / 14

We can use a calculator or look up the value of cos(24°) to get:

cos(24°) ≈ 0.913

Solving for AC, we get:

AC = 14 x cos(24°) ≈ 12.67

Thus, BC is about 5.72 miles long while AC is about 12.67 miles in length.

-3 > x

Move the variable to the left and flip the inequality

x < -3

Answer:

x = 98

Step-by-step explanation:

Solve for x:

(x - 14)/7 = 12

Multiply both sides of (x - 14)/7 = 12 by 7:

(7 (x - 14))/7 = 7×12

(7 (x - 14))/7 = 7/7×(x - 14) = x - 14:

x - 14 = 7×12

7×12 = 84:

x - 14 = 84

Add 14 to both sides:

x + (14 - 14) = 14 + 84

14 - 14 = 0:

x = 84 + 14

84 + 14 = 98:

Answer:  x = 98

The answers are n= -8/3 or 3

Changes made= n2 was replaced by n^2 and making the equation 3n²-n-24=0

Factoring 3n²-n-24

   The first term is,  3n² its coefficient is  3 .

   The middle term is,  -n  its coefficient is  -1 .

   The last term, "the constant", is  -24

Step 1: Multiply the coefficient of the first term by the constant   3 • -24 = -72

Step 2: Find two factors of  -72  whose sum equals the coefficient of the middle term, which is   -1 .

      -72    +    1    =    -71

     -36    +    2    =    -34

     -24    +    3    =    -21

     -18    +    4    =    -14

     -12    +    6    =    -6

     -9    +    8    =    -1

Step 3: Rewriting the polynomial splitting the middle term using the two factors found in step 2 above,  -9  and  8

                    3n2 - 9n + 8n - 24

Step 4: Adding up the first 2 terms, pulling out like factors :

                   3n • (n-3)

             Adding up the last 2 terms, pulling out common factors :

                   8 • (n-3)

Step 5: Adding up the four terms of step 4 :

                   (3n+8)  •  (n-3)

            Which is the desired factorization

The equation at the end of second equation:

(n - 3) • (3n + 8)  = 0

           Add  3  to both sides of the equation :

                         n = 3

           Subtract 8  from both sides of the equation :

                            3n = -8

            Divide both sides of the equation by 3:

                     n = -8/3 = -2.667

The answers are n= -8/3 or 3

The solution is y = -2x + 2

The equation of line that passes through the point P ( -2 , 6 ) and is perpendicular to the line x - 2y = 7 is given by y = -2x + 2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Let the point be P = P ( -2 , 6 )

The line is perpendicular to the line x - 2y = 7

So , the product of the slopes of the lines will be -1

And , m₁ x m₂ = -1

Now , the slope of the line x - 2y = 7 is calculated as

x - 2y = 7

Adding 2y on both sides of the equation , we get

2y + 7 = x

Subtracting 7 on both sides of the equation , we get

2y = x - 7

Divide by 2 on both sides of the equation , we get

y = x/2 - 7/2

The equation is of the form y = mx + b where m is the slope and b is the y-intercept

So , the slope of the line m₁ = 1/2

Now , since the lines are perpendicular

the product of the slopes of the line will be -1

And , m₁ x m₂ = -1

Substituting the values in the equation , we get

1/2 x m₂ = -1

Multiply by 2 on both sides of the equation , we get

m₂ = -2

Therefore , the slope of the line A is -2

Now , the equation of line A is given by the formula

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 6 = -2 ( x - ( - 2 ) )

y - 6 = -2 ( x + 2 )

y - 6 = -2x - 4

Adding 6 on both sides of the equation , we get

y = -2x + 2

Hence , the equation of line is y = -2x + 2 where slope of the line is -2 and the y intercept is 2

The inequality x + y > 15 would not be valid in this system. This inequality states that the total number of hours that you and your friend drive together is greater than 15 hours, but we know that the trip will take no more than 15 hours to complete. Therefore, this inequality is not valid.

The other inequalities in the system are:

x < 8, because you want to drive less than 8 hours

y > 10, because your friend agrees to drive at least 10 hours

x + y <= 15, because the trip will take no more than 15 hours to complete.

These inequalities are all valid and can be used to determine the possible number of hours that you and your friend will drive on your road trip.

Answer:

Step-by-step explanation:

a) The amount of their account on July 1 can be found by calculating the balance of the account at the end of the first six months and then adding the second $2,000 deposit:

balance at end of first 6 months = $2,000 * (1 + 0.06/2)^2 = $2,060.60

total balance on July 1 = $2,060.60 + $2,000 = $4,060.60

b) The balance of the account one year later on January 1 can be found by calculating the balance at the end of the second six months and adding it to the balance at the end of the first six months:

balance at end of second 6 months = $2,060.60 * (1 + 0.06/2)^2 = $2,123.36

total balance on January 1 = $2,123.36 + $2,060.60 = $4,183.96

c) The compound interest can be found by subtracting the initial deposit from the balance one year later:

compound interest = $4,183.96 - $2,000 = $2,183.96

Answer:

The pattern is that each number in the sequence is the previous number minus 1.5. For example, -5.5 is -4 minus 1.5, -7 is -5.5 minus 1.5, and so on.

Answer:

-1.5

Step-by-step explanation:

You take two of the variables in the pattern and subtract them with the second one being the minuend, and the first being the subtrahend.

For example we will use -4 and -5.5

(-5.5) - (-4) = -1.5

There is a negative sign present so it indicates subtraction towards the pattern.

Hence, the pattern change rate is -1.5
