Step-by-step explanation:

$m \angle \: a + 80 \degree = 180 \degree \\ (linear \: pair \: \angle s) \\ \therefore \: a = 180 \degree - 80 \degree \\ \huge \red { \boxed{\therefore \: a = 100 \degree}} \\ \\ \huge \purple { \boxed{m \angle \: b = 80 \degree }} \\ (corresponding \: \angle s) \\ \\ m \angle \: c=m \angle \: a \\ (vertical \: \angle s) \\\huge \orange { \boxed{ \therefore \: m \angle \: c = 100 \degree}}$

alex needs to buy compressed air to fill 5 empty cylindrical tanks for his store. each tank is 12 feet deep and has a radius of

Yanka [14]

Volume of a cylinder = the area of the base x height of the cylinder
Area of base = $\pi$ r^2
A = 6^2( $\pi$ )
A = 36 $\pi$
V = 36 $\pi$ x 12
V = 432 $\pi$

5 cylinders = 5V

5V = 5 x (432 $\pi$ )
5V = 2160 $\pi$

Final answer: Alex needs to buy 2160 $\pi$ or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.

9966 [12]

9514 1404 393

Answer:

4 pounds

Step-by-step explanation:

Let b represent the pounds of bananas Mrs. Davis bought. The weight of strawberries would be (7-b) and their cost would be 4×0.50 = 2.00 per pound. Her total purchase was ...

0.50b + 2.00(7 -b) = 8.00

-1.50b +14 = 8 . . . . simplify

6 = 1.50b . . . . . . add 1.50b -8

4 = b . . . . . . . . divide by 1.50

Mrs. Davis bought 4 pounds of bananas.
