Answers

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

Answer:

b, x = 17

Step-by-step explanation:

A right angle (as shown by the box in the corner of the angle) is 90°.

So, the two angles have to add up to 90°.

22 + 4x = 90

Subtract 22 from both sides.

4x = 68

Divide both sides by 4.

x = 17

The answer is b, 17

Marta told Maribel “The sum of fifty and half the number of oranges is the same as one-hundred-twenty.” Maribel wrote 50 (one-half) + m = 120 What is her error?

Answers

Answer:

Her error was that the half should have been multiplied by m, instead

[tex]50 + \frac{1}{2}m = 120[/tex]

Step-by-step explanation:

Given

[tex]Base\ Amount = 50[/tex]

[tex]Rate = 0.05[/tex]

[tex]Days = n[/tex]

So, we have:

[tex]Base\ Amount + Rate * days = 120[/tex]

[tex]50 + \frac{1}{2}m = 120[/tex]
