B= (v/a^2)-5 should be correct.
Yikes... my answer is in the comments because I didnt realize. All you have to do is take the formula of a circles area and substitute the area and basically work backwards. I got the radius is the square root of 1
Answer:
Step-by-step explanation:
The time (minutes) vary directly with the number of walls and inversely to the number of people.
m = kw/p, where m = minutes, w = walls, and p = people
60 = 5k/7
420 = 5k
84 = k
m = 10(84)/10
m = 84
They’re complimentary angles (add up to 90)
Answer:
L = 324 cm²
S = 359.1 cm²
Step-by-step explanation:
Lateral surface area of a triangular prism is given by,
Lateral surface area = Perimeter of the triangular base × Height
= (9 + 9 + 9)×12
= 27 × 12
= 324 cm²
Surface area area of the triangular prism = Lateral area of the prism + Area of the triangular bases
= 324 + ![\frac{1}{2}(Base)(Height)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28Base%29%28Height%29)
= 324 + ![\frac{1}{2}(9)(7.8)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%289%29%287.8%29)
= 324 + 35.1
= 359.1 cm²
