A car rental company charges a flat rate of $247 plus a daily rate of $53. 7)Write an equation to represent the total cost of renting a car for a certain number of days. Define your variables.

8) If you were charged $671 for renting a car, how many days did you rent the car for?

Answers

Answer 1
Answer:

Answer:

7) C = 247 + 53d

8) 8 days

Step-by-step explanation:

7)

Let "C" represent the total cost of renting a car.

Let "d" represent the number of days the car is rented.

The equation to represent the total cost of renting a car for a certain number of days is:

C = 247 + 53d

8)

To find the number of days the car was rented when the total cost is $671, we can substitute the values into the equation and solve for "D."

671 = 247 + 53d

424 = 53d

d = 8

So, the car was rented for 8 days.

Givivn h(x)=-x+1, solve for x when h(x)=0

Answers

Answer:

x = 1

Step-by-step explanation:

given h(x) = - x + 1

when h(x) = 0 , that is

- x + 1 = 0 ( subtract 1 from both sides )

- x + 1 - 1 = 0 - 1 ( simplify both sides )

- x = - 1 ( multiply both sides by - 1 )

- 1 × - x = - 1 × - 1 , that is

x = 1

The bull’s-eye on a target has diameter 2 in. What is the area of the bull’s-eye to the nearest tenth? Use 3.14 for π.

Answers

Answer:

20.3cm^2

Step-by-step explanation:

Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2

Díameter is 2 inches = 5. 08cm

But radius = diameter /2

Radius = 5.08cm /2

Radius = 2.54cm

Hence Area of bulleyse = 3.14 x (2.54) ^2

= 3.14 x 6. 451 cm^2

= 20.256 cm^2

=20.3cm^2 (to nearest tenth)

How do you write 56/50 as a percentage

Answers

Answer:

112%.

Step-by-step explanation:

To write 56/50 as a percentage, you can follow these steps:

1. Divide the numerator (top number) by the denominator (bottom number): 56 ÷ 50 = 1.12.

2. Multiply the result by 100 to convert it to a percentage: 1.12 × 100 = 112%.

Therefore, 56/50 can be written as 112%. This means that the fraction 56/50 is equivalent to 112 out of 100, or 112%.

Example:

Let's say you have 56 apples and you want to express it as a percentage of a total of 50 apples. To find out what percentage 56 apples is out of 50, you can use the fraction 56/50. By following the steps above, you find that it is equal to 112%. This means that 56 apples represents 112% of the total of 50 apples.
