This is how you would determine the equation and solve the problem:

- First, it is important that you find how much each eraser cost. You do know that 66 erasers cost $6.60. So create an equation.

- The equation would be: 66/6.60

which means each eraser was 10 cents each

- Now you can create a equation that would determine the cost of 333 erasers since you know how much each eraser actually cost. The equation would be:

- .10×333=?

To create that equation all you need to do is multiply the price of the erasers (10 cents) by how many erasers you are buying (333).

A bicycle wheel has an inside radius of 12 inches. Which expression could be used to find the inside circumference of this wheel

il63 [147K]

Step-by-step explanation:

We have given that,

The inner radius of a bicycle wheel is 12 inches.

It is required to find the expression to find the inside circumference of this wheel.

The outer surface of the wheel is equal to its circumference. It is given by :

$C=2\pi r$

r is radius of wheel

$C=2\times 3.14\times 12\\\\C=75.36\ \text{inches}$

This is the required explanation.

$5000 was invested into an investment that pays 4.25% simple interest. The total value of the investment amounted to $6593.75. H

Basile [38]

Answer:

7.5 years

Step-by-step explanation:

P = $5000,

R = 4.25%,

A = $6593.75,

N =?

SI = A - P = 6593.75 - 5000 =$1593. 75

$\because \: SI = \frac{ PNR}{100} \\ \\ \therefore \: 1593.75 = \frac{5000 \times N \times 4.25}{100} \\ \\ \therefore \: 1593.75 \times 100 = 21,250 \times N \\ \\ N = \frac{159375}{21250} \\ \\ N = 7.5 \: years \:$

What’s the domain and range? An airplane travels at 565 mph.

viktelen [127]

Answer:

Domain:

The domain of this can be any value between 0 to 565 miles per hour

Range:

The reasonable range can be the distance traveled which can be from 0 to 13,560 miles (no plane travel is longer than 24 hours, we assume).

Step-by-step explanation:

Domain is the input, set of x values for the function.

Range is the output, set of y values for the function.

This isn't a function essentially, but it is given that an Airplane travels at 565 miles per hour.

We can say that the domain will be the speed of the airplane and the range would be the distance it travels.

Domain:

The domain of this can be any value between 0 to 565 miles per hour

Range:

The reasonable range can be the distance traveled which can be from 0 to (565*24=13,560 miles) 13,560 miles (no plane travel is longer than 24 hours, we assume).
