Answer:

The composite area is a total of 62 square inches.

Step-by-step explanation:

You're given three rectangles of different width and height. To find the correct answer, you need to find the sum of each rectangles' area.

first though we need to find the height of the middle rectangle. We are told the total height and the other two rectangles' heights, so we just need to subtract the others' heights from the total:

10 - (4 + 1.5)

10 - 5.5

= 4.5

So the middle rectangle is 4x4.5 inches, giving it an area of 18 square inches

The top one is 8x4 inches for a total of 32 square inches.

And the bottom one is 1.5x8 inches, for a total 12 square inches.

If we add them all up, that's 18 + 32 + 12 square inches, or 62 square inches.

Mikaela placed a frame around a print that measures 10 inches by 10 inches. The area of just the frame itself is 69 square inche

olchik [2.2K]

Answer:

1.5 in

Step-by-step explanation:

Let x be the width of the frame.

Side of print=10 in

Area of frame=69 square in

We have to find the width of the frame.

Side of frame=10+x+x=10+2x

Area of square= $(side)^2$

By using the formula

Area of print= $10\times 10=100in^2$

Area of frame with print= $(10+2x)^2$

Area of frame=Area of frame with print-Area of print

$69=(10+2x)^2-100$

$(10+2x)^2=69+100=169$

$(10+2x)=\sqrt{169}=\pm 13$

$10+2x=13$

Because Side is always positive.

$2x=13-10=3$

$x=\frac{3}{2}=1.5$

Hence, width of frame=1.5 in

Which equations have a lower unit rate than the rate represented in this table?

grandymaker [24]

Answer:

A and D

Step-by-step explanation:

Find the unit rate of the data in the table:

y = kx
2 = 6k
k = 2/6
k = 1/3

The equation is:

y = 1/3x

Compare this with the others:

A. 3/11 < 1/3 = 3/9 ⇒ yes
B. 2/5 > 1/3 = 2/6 ⇒ no
C. 9/23 > 1/3 = 9/27 ⇒ no
D. 4/13 < 1/3 = 4/12 ⇒ yes
E. 3/8 > 1/3 = 3/9 ⇒ no
