Answer:

Jada and lin are comparing inches and feet.

Let I denote inches and F denote feet.

It is given that

I =k F or F=m I

So, I/F=k or m=F/I

As we know 1 feet = 12 inches

constant of proportionality i.e k=1/12

In case 2, constant of proportionality=12/1=12

So, Jada must have calculated ratio of feet to inches while Lin has calculated the ratio of inches to feet.

The figure shows a plastic holder for two cups. Which numerical expression gives the area of the top of the plastic?

Answer:

(10*5) - 2(pi(2.5)^2)

Step-by-step explanation:

First we find the area of the rectangle. This is (10*5) since the diameter of the circles is 5 (half of 10) which means that the width of the rectangle is 5, and that the length is 10.

We then find the area of the two circles. One circle can be found using the radius (2.5)(half of the diameter, 5). This gives us pi(2.5)^2 for one circle. We multiply this by two to account for both circles. Then we subtract that from the area of the rectangle to find out how much the area of the plastic is.

This gives us (10*5) - 2(pi(2.5)^2)

Answer:

D:95 mm Hg

Step-by-step explanation:

Using the linear model, y=x+95, x represents the age and y represents the blood pressure.

For a newborn, x=0 this gives us

> y=0+95 = 95<
