Can some1 pls explain to me how to do this??! Katrina is building a deck. She cuts 3 lengths of wood from a 72-inch board. The f

uysha [10]

Rewriting the question, the given lengths that were cut from the board were 30 3/4 inches, 12 1/4 inches, and 16 1/4 inches. To obtain the remaining length of the board, all of the measurements cut are to be added and subtracted from 72 inches. This is shown below:

30 3/4 + 12 1/4 + 16 1/4 = 237/4 = 59.25 inches.

Remaining length of board = 72 - 59.25 = 12.75 inches.

Therefore, there will be 12.75 inches remaining of the board.

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written using

kozerog [31]

Answer:

f(x) = - 3x + 4

Step-by-step explanation:

Given

9x + 3y = 12

We require to rearrange expressing y in terms of x

Subtract 9x from both sides

3y = - 9x + 12 ( divide all terms by 3 )

y = - 3x + 4

Expressed in functional notation by replacing y by f(x), that is

f(x) = - 3x + 4

Jim went by bus to visit his uncle. He left at 10 A.M. and arrived at 4 P.M. The bus traveled 270 mi. What was its average speed

Feliz [49]

Answer:

Average speed, S = 45 mph

Step-by-step explanation:

Given the following data;

Take-off time = 10 AM

Arrival time = 4 PM

Distance = 270 miles

To find the average speed of the bus;

First of all, we would determine the total time.

10 AM to 4 PM = 6 hours

Total time = 6 hours

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting into the formula, we have;

$Speed = \frac{270}{6}$

Average speed, S = 45 mph

Therefore, the average speed of the bus is 45 miles per hour.
