Answer:
16
Step-by-step explanation:
Convert 6 inches to 1/8" to make it easier.
1/8 just means there are 8 parts in a whole. 8*6=48.
There are forty-eight 1/8s in 6 inches. 48 divided by 3 (since you have <u>3</u>/8 inch books) will give you your answer: 16
Hope that helps.
P.S. Please consider for brainliest if it did help. I need 2 more to rank up.
Answer:
y=-9x+193
Step-by-step explanation:
Its decreasing by 9, and 175+(9x2) is 193
Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8
Answer: The length of a diagonal brace is 8 feet.
Answer:
118.3 m²
Step-by-step explanation:
Step 1. Calculate the <em>semiperimeter</em> (s).
s = (p + q + r)/2
s = (17 + 18+ 15)/2
s = 50/2
s = 25 m
===============
Step 2. Calculate the <em>area</em> (A).
Use <em>Heron’s formula</em>:
A = 118.3 m²
