Where
r = radius = diameter / 2 = 20 / 2 = 10 feet
When we round this to the nearest whole number:
Where
r = radius = diameter / 2 = 20 / 2 = 10 feet
When we round this to the nearest whole number:
Answer: 313
Step-by-step explanation:
Let x be the attendance before the drop.
Given: An article reports, "attendance dropped 4% this year, to 300.
Wec can write 4% = 0.04
Then, 4% of x = 0.04x
Now according to the question we have:-
Hence, the the attendance before the drop = 313
Answer: see below
<u>Step-by-step explanation:</u>
12) 2(x + 4) = 8
<u> ÷2 </u> <u> ÷2 </u>
x + 4 = 4
<u> -4 </u> <u> -4 </u>
14) 4w - 2(1 - w) = -38
4w -2 + 2w = -38
(4w + 2w) - 2 = -38
6w - 2 = -38
<u> +2 </u> <u> +2 </u>
6w = -36
<u> ÷6 </u> <u> ÷6 </u>
16) 10(1 - 2y) = -5(2y - 1)
10 - 20y = -10y + 5
<u> +20y </u> <u>+20y </u>
10 = 10y + 5
<u> -5 </u> <u> -5 </u>
5 = 10y
