Answer:
Step-by-step explanation:
let me think aha!
1 acre = 43560 square feet
43560 = 484 * X
X=43560/484 = 90
the width = 90 feet
Answer:
90°
Step-by-step explanation:
sum the parts of the ratio 2 + 6 + 8 = 16
The sum of the 3 angles in a triangle = 180°
divide 180 by 16 to find the value of one part of the ratio.
= 11.25° ← 1 part of the ratio
8 parts = 8 × 11.25° = 90°
The largest angle in the triangle is 90°
D because for a sequence you can't have a -1st term so b is out and a and c mean the same thing so neither of them can be the answer
3.9 * 5.3 ≈ 4 * 5
≈20
Well after doing your multiplication, you can place your decimal point by knowing that from estimation the answer is around 20.
So you can place your decimal point after the first two digits from the left.
