Answer:

25 in.

Step-by-step explanation:

In a rectangle the diagonals bisect each other.

Therefore PT = TR = ST = TQ = 12.5 in.

PR = PT + TR = 12.5 + 12.5

= 25 in.

Answer: its 25 because you're adding the whole line from P to R, so 12.5 + 12.5 is 25

Step-by-step explanation:

P to T is 12.5

T to R is 12.5

Add those together

12.5 + 12.5 gives you 25

Answer:

The student is expected to spend <em>15.4 hours </em>doing homework

Step-by-step explanation:

The scattered plot shows there is a close correlation between the variables. A line of best fit will go through the 'center' of the points. Since we are not required to find an exact line, we'll draw it in red color as shown below

To know the equation of that line, we must take two clear points of it from the graph. We'll pick (28,4) and (4,25)

The equation of a line, given two points (a,b) and (c,d) is

$\displaystyle y-b=\frac{d-b}{c-a}(x-a)$

Using the selected points

$\displaystyle y-4=\frac{25-4}{4-28}(x-28)$

Simplifying and computing results, the equation is

$\displaystyle y=-\frac{7}{8}x+\frac{57}{2}$

Using that equation, we can predict how many hours the students will spend doing homework if they spend 15 hours watching TV

$\displaystyle y=-\frac{7}{8}(15)+\frac{57}{2}$ =15.4 hours

So the student is expected to spend 15.4 hours doing homework

a force of 2 pounds is needed to stretch a spring 8 inches.what force is required to stretch the spring 16 inches

Korvikt [17]

Answer:

Four (4) pounds

Step-by-step explanation:

Because we required two (2) pounds to stretch the spring eight (8) inches, we need double the force to stretch it sixteen (16) inches. Sixteen is just double the original amount, meaning we need four (4) pounds to stretch the spring sixteen inches.

Hope this helps!

How do i turn standard form into slope intercept?

Jlenok [28]

Write it in y= mx+b form. Subtract 5x from both sides to get 4y = -5x + 100. Divide by 4 so the answer would be y= -5/4x + 25.

What is the y-intercept of y=4x?

Vera_Pavlovna [14]

Answer:

y intercept= 0

Step-by-step explanation:

in the formula y=mx+b, m is the slope and b is the y intercept. here we are not given "b" so the y intercept it 0
