Answer:

<h3>Figure 1</h3>
  • Perimeter of base = 5 + 5 + 8 = 18 ft
  • Height = 7 ft
  • Base area = 1/2(8)(3) = 12 ft²

<u>Surface area:</u>

  • S = 18*7 + 2*12 = 150 ft²
<h3>Figure 2</h3>

<u>Surface area of cube:</u>

  • S = 6a² = 6(2.5)² = 37.5 m²

<u>Surface area of prism:</u>

  • S = 2(11 + 9)(7) = 280 m²

<u>Overlapping area:</u>

  • S = 2.5² = 6.25 m²

<u>Surface area of composite figure:</u>

  • S = 280 + 37.5 - 2(6.25) = 305 m²

A new company president is said to have caused the company "to do a 180." Before the new president, the company was losing 10,00
bezimeni [28]

Answer:

<u>Earning </u>10,000 per month.

Step-by-step explanation:

Since a "180" usually refers to an opposite, the opposite of "losing 10,000 per month" would happen.

So, the company would be <u>earning </u>money instead of losing money.

Alice's grandmothers age is a composite number between 70 and 80 and has a factor of 11 what is it
pshichka [43]

The factor of 11 is going to be 77 because you have to stay in between 70 to 80

and 7 times 11 is 77. It also has to be a number in the 11 timetables. It can't be 88 because we can't cross 80 so the factor is going to be 77.


Hope it helps
