Answer:
A) 1020 cm²
Step-by-step explanation:
8 sides
2[(½×15×16.4) + (½×10×17.3) + (½×15÷23.8) + (½×10×24.2)]
2(510)
1020 cm²
Answer:
p = 7
Step-by-step explanation:
Step 1: Subtract 2p from both sides.
5p − 9 − 2p = 2p + 12 − 2p
3p − 9 = 12
Step 2: Add 9 to both sides.
3p − 9 + 9 = 12 + 9
3p=21
Step 3: Divide both sides by 3.
= 
p = 7
Answer:
61.15 m
Step-by-step explanation:
From trigonometry :
Tan x = opposite / Adjacent
x = 28°
Tan 28 = distance from base to fire / height
0.5317094 = distance from base to fire / 115
distance from base to fire = 115 * 0.5317094
distance from base to fire = 61.15 m
Answer:
f(5) = 23
Step-by-step explanation:
replace the x in the equation with 5 and solve from there
Answer:
31.5
Step-by-step explanation:
The area of a triangle is 1/2 * b * h
so base times height times one half
