Answer:

36 pieces

Step-by-step explanation:

4 1/8 ft x 4 1/8 ft = 49.5 in x 49.5 in = 2450.25 in^2

8.25 in x 8.25 in = 68.06 in^2

2450.25/68.06 = 36 pieces

checking for scrap loss:

49.5/8.25 = 6

so no scrap loss

Simultaneous equation refer to a pair of equations that are solved at the same time.

<h3>What is a simultaneous equation?</h3>

A  simultaneous equation refer to a pair of equations that are solved at the same time.

For problem 1;

x = 4 - y ------ (1)

y^2 = 3x + 19 ----- (2)

Substitute (1) into (2)

y^2 = 3(4 - y) + 19

y^2 = 12 - 3y + 19

y^2 +3y - 31 =0

y = 4.27 or -7.27

x = 4 - 4.27 = 0.27

or

x = 4 - (-7.27) = 11.27

For the second problem;

x = 7 - y

y^2 = 5x - 15

Substitute (1) into (2)

y^2 = 5(7 - y) - 15

y^2 =35 -5y -15

y^2 + 5y - 20 = 0

y =2.62 or -7.62

x = 7 - 2.62 = 4.38

OR

x=  7 - (-7.62) = 14.62

The answer is x=5 because 24-3-5=16 so you have to get those 2 sides to equal 16....2*5=10+1=11 then add 5 and you get 16

Juno is taking a taxi. The table represents a linear function and shows the amount she owed after various numbers of miles trave
Gennadij [26K]

(B) - Yes, because the amount owed changes by 2.25 every time the miles change by 1.


Starting at 1 mile the price is 2.5 dollars.

Mile 2 is 4.75 dollars. What is the difference between 4.75 and 2.5? 2.25

Mile 3 is 7 dollars. What is the difference between 7 and 4.75? 2.25

Mile 4 is 9.25 dollars. What is the difference between 9.25 and 7? 2.25

Mule 5 is 11.5 dollars. What is the difference between 11.5 and 9.25? 2.25

The change is always 2.25 dollars.

The change is 2.25 dollars per mile.

One way to solve for this is (11.5 - 2.5)/(5-1)=2.25

This is (y2-y1)/(x2-x1). By picking 2 points, (x1,y1) and (x2,y2) you can solve for the slope (rate of change) between them.
