Answer:
Step-by-step explanation:
7 feet 1 foot is 12 inches
7*12= 84 inches.
None of the choices are correct.
90 inches is 7.5 feet
62.5 inches is 5.2 feet
75 inches is 6.25 feet
The ratio from 80 to 5 would be 16. so divide 144 by 16 and you get 9. Answer:9
2x + 6 < x + 20
- x - x
x + 6 < 20
- 6 - 6
x < 14
Solution Set: (-∞, 14)
Because it is normally set to only find real roots, not complex roots
if you are smart, you can use the factor function and use your head to find those roots
Answer:
79 units²
Step-by-step explanation:
The area of a circle is found by using the formula A = π x r². Since we are not given the radius we can use the formula r = C / (2π). Substituting in the given values, we get r = 31.5/(2π). 2 times pi is 6.283185307. 31.5 divided by this will get you 5.013380707. Now, put that value in for r in the area equation. A = π x 5.013380707². Pi times 5.013380707² equals 78.96074613. This can be rounded to 79. (Or 80 if you need to the nearest whole number.)
