Answer:

  24 years

Step-by-step explanation:

You want to know the number of years it will take an account's value to exceed $300, given it was opened with $100 and earns 4.8% interest compounded annually.

The value of the account earning compound interest is ...

  A = P(1 +r)^t

where principal P is earning interest at rate r for t years.

Solving for t, we get ...

  A/P = (1 +r)^t

  log(A/P) = t·log(1+r)

  t = log(A/P)/log(1 +r) = log(300/100)/log(1 +0.048)

  t = log(3)/log(1.048) ≈ 23.433

For the value to exceed $300, it will take 24 years.

Answer:

Axis of Symmetry: x = 1

Vertex: (1,7)

Step-by-step explanation:

The standard form of an equation for a parabola is

ax² + bx + c

So converted to standard form, the equation is

y = -x² + 2x + 6,

where

a = -1,  b = 2, and c = 6

The axis of symmetry of a parabola follows the formula

x = -b/(2a)

--> x = -2/(2*(-1))

--> x = 1

This is also the x-coordinate of the vertex.

To get the y-coordinates of the vertex, substitute 1 into x:

y=6+2x-x²

y=6+2(1)-(1)²

y = 7

So the coordinates of the vertex is (1,7)

To graph the relationship between the pool's water level and time, we can start by creating a table of values for the water level at different times. Here is an example of such a table:

Time (minutes) Water Level (centimeters)

0 0

1 6

2 12

3 18

4 24

5 30

6 36

7 42

14 84

15 90

16 96

17 102

18 108

19 114

20 120

We can then plot these values on a graph, with the time on the x-axis and the water level on the y-axis. The resulting graph would be a straight line that slopes upwards, starting at the origin (0, 0) and ending at (20, 120).

The graph shows that the water level in the pool increases linearly with time. The slope of the line represents the rate at which the water level is increasing, which in this case is 6 centimeters per minute.

Step-by-step explanation:

The equation of the line is (b) y = 2.25x - 6.25

From the question, we have the following parameters that can be used in our computation:

Points = (3, 1/2) and (5, 5)

A linear equation can be represented as

y = mx + c

Substitute the known values in the above equation, so, we have the following representation

1/2 = 3m + c

5 = 5m + c

Subtract the equations

2m = 4.5

Divide by 2

m = 2.25

Substitute m = 2.25 in 5 = 5m + c

5 = 5 * 2.25 + c

So, we have

c = 5 - 5 * 2.25

Answer:4:15

Step-by-step explanation:

Answer:

4:15.

Step-by-step explanation:

The long hand (minute) is on the 3 and the short hand (hour) is past the 4. The time is 4:15.

The speed of car is 50 miles per hour and the speed of the motorcycle is 40 miles per hour.

Let M = speed of the motorcycle.

Hence, speed of the car = 2M - 30.

Distance covered = Time taken x Speed.

Hence in 2 hours,

Distance covered by motorcycle = 2M

Distance covered by car = 2(2M-30).

Given, the car is 20 miles ahead of the motorcycle.

Hence,

2(2M-30) = 2M + 20

4M-60 = 2M + 20

2M = 80

M = 40

2M-30 = 2(40)-30 = 80-30 = 50

Therefore, speed of motorcycle is 40 miles per hour and speed of car is 50 miles per hour.

For a rectangle of length L and width W, the area is given by the formula:

A = L*W

Here we know that the rectangular room has an area of 352 square feet, and we also know that the length of the room is 6 feet mroe than the width of the room, then we can write a system of equations:

352 = L*W

L = W + 6

To solve that system, we can substitute the second equation in the first one, we will get:

352 = (W + 6)* W

352 = W^2 + 6W

W^2 + 6W - 352 = 0

So we have a quadratic equation, the solutions give:

[tex]W = \frac{-6 \pm \sqrt{6^2 - 4*1*(-352)} }{2} \\\\W = \frac{-6 \pm 38 }{2}[/tex]

The surface area of a sphere is 2461.76 units.

Step-by-step explanation:

where,

π = 3.14 or 22/7

r = radius of sphere

Here, we know that

radius = diameter ÷ 2 = 28/2 = 14 units

So,

A = 4 π r²

A = 4 × 3.14 × (14)² units

A = 12.56 × 196 units

A = 2461.76 units

Thus, The surface area of a sphere is 2461.76 units.

Answer:  the surface area of the sphere of diameter 28cm is 2464 cm²

Step-by-step explanation:

     Given, diameter = 28 cm

      hence, radius of the sphere = d/2 = 28/2 =14 cm

 Therefore, the surface area of a sphere of radius (r) = 4пr²

                 where п= 22/7= 3.14

                                            = 4×3.14×14×14

                                            = 2464 cm²

Answer:

its d I did the test hope its helps

Answer:

c = 5

Step-by-step explanation:

The slope is the change in y over the change in x. Or as I memorized RISE OVER RUN. Also in physics, you can write ∆y/∆x. Delta (∆) just means change.

Using this equation we have

The slope = m = 3 = ∆y/∆x

m = (-1 - c)/(-8 - -6) = (-1 - c)/(-8+6) = (-1 - c)/(-2) = 3

Now multiply both sides of the equation by -2 and you get

(-1 - c) = 3•(-2) = -6

Almost there!

Now we have the equation

-1 - c = -6

Add one to both sides and you get

-1+1-c = -6 +1

Simplified that equals

-c = -5

Then to get our answer we have to go from negative to positive.

Multiplying both sides by -1 we get

-1 • -c = -1 • -5

c = 5

Now CHECK!

Plug c into the equation ∆y/∆x and you get a slope of 3 which proves the answer is right.

Step-by-step explanation:

Answer:

144.97

Step-by-step explanation:

First, write the problem as an equation : P% × Y = X

Here, P is 7.63, Y is 19, so the equation to solve is 7.63% × 19 = X

Convert 7.63% to fraction

To convert a percent to a fraction, just remove the percent sign and divide the given number by 100

7.63% = 7.63/100

Substitute 7.63/100 instead of 7.63% in the above equation, then 7.63% × 19 = X becomes 7.63/100 × 19 = X

Solve for X:

X = 7.63/100 × 19

X = (7.63×19)/100

x = 144.97/100 = 1.45

Therefore, 7.63% of 19 is 1.45

In the given case we can conclude that when,   7.63 multiplied by 19 equals 145.97.

To multiply 7.63 by 19, we can use the standard method of multiplication. Step 1: Write the numbers vertically, with the larger number on top: 7.63 x 19 Step 2: Start by multiplying the ones place digit (3) of the bottom number (19) by each digit of the top number (7.63). 3 * 7.63 = 22.89 Step 3: Write down the result below the line, making sure to align the decimal point: 22.89

Step 4: Next, multiply the tens place digit (1) of the bottom number (19) by each digit of the top number (7.63). 1 * 7.63 = 7.63 Step 5: Write down the result, shifting it one place to the left: 7.63 22.89 ------ 145.97 Step 6: Finally, add the two partial products together to get the final answer: 22.89 +145.97 ------- 145.97 Therefore, 7.63 multiplied by 19 equals 145.97.

Answer:
You sold 15 vegetarian sandwiches and 10 turkey sandwiches.

Step-by-step explanation:

First, let's call the number of vegetarian sandwiches sold "V" and the number of turkey sandwiches sold "T".

We can set up the following equation: 3V + 4T = 85

Next, we need to find the values of V and T that satisfy this equation. To do this, we can use the fact that V and T must be whole numbers since we cannot sell a fraction of a sandwich.

We can start by trying V = 1 and T = 6. Plugging these values into the equation, we get: 3(1) + 4(6) = 18 + 24 = 42

Since 42 is not equal to 85, this means that V and T cannot both be 1 and 6.

We can try other values of V and T that are whole numbers until we find a combination that satisfies the equation. One way to do this is to use trial and error.

For example, we can try V = 2 and T = 5, which gives us: 3(2) + 4(5) = 6 + 20 = 26 This is still not equal to 85, so we can try other values. We can also use the fact that V + T = 25 (since we sold a total of 25 sandwiches) to help us solve the equation.

If we set V + T = 25, then we can rewrite the original equation as: 3V + 4(25 - V) = 85 Solving for V, we get: 3V + 100 - 4V = 85 Combining like terms, we get: -V = 15 Dividing both sides by -1, we get: V = 15

Since V + T = 25, this means that T = 25 - 15 = 10

Therefore, we sold 15 vegetarian sandwiches and 10 turkey sandwiches.
