Answer:

528

Step-by-step explanation:

Surface area of bottom block + Surface area of top block - 2(Shared surface area)

Bottom block: 2(10*12) + 2(5*12) + 2(5*10) = 240 + 120 + 100 = 460 square inches

Top block: 2(2*2) + 4(2*8) = 8 + 64 = 72 square inches

Shared surface area = 2*2 = 4 square inches

Plugging into our formula:

460 + 72 - 4 = 528 square inches

1. In the figure, m DE=124, and M BC=36. The diagram is not drawn to scale. What is m A? A) 44* B) 62* C) 80* D) 88* please help
Anuta_ua [19.1K]

The relation between arc length and exterior angle is given in the figure.

Now we are given far arc length as DE =124

We are given near arc length as BC = 36

So plugging in the formula to find measure of angle A:

angle A=\frac{far arc-near arc}{2}

angle A=\frac{124-36}{2}

angle A=\frac{88}{2}

Angle A = 44 degrees

Answer : A) 44 degree

nordsb [41]

Answer:

12 units

Step-by-step explanation:

Allow me to revise your question for a better understanding and I hope it will fit the original one.  

The parallelogram shown below has an area of 72 units squared. The base is 6 and the other side is 13 Find the missing height.

Here is my answer:

Given:

The area: 72 units squared.

The base: 6 units

As we know that the area of the parallelogram is represented by below formula:

A = b*h where h is the height and b is the base

In this situation, we know:

72 = 6*h

<=> h = 12

So the missing height is 12 units

If a line falls on the points (3, 1) and (9,5), what is its slope? Enter your
Anvisha [2.4K]
<h3>Answer:  2/3</h3>

============================================================

Use the slope formula to get that answer

m = (y2-y1)/(x2-x1)

m = (5-1)/(9-3)

m = 4/6

m = 2/3

We have a rise of 2 and a run of 3.

In other words, we move up 2 and over to the right 3.

Monganville and Newton are 24 miles apart. On a map the two cities are 3 inches apart. What is the map scale?
Reil [10]

One inch equals 8 miles, or in math terms, this is how we figure It out...

24m = 3in

To find the scale we need to find what one inch equals on the map, dmto do this we divide both sides by 3 in. and get 8 miles in reality equals one map inch.
