im right
The answer is x = -4 or x = 9
A=(απr^2)/360=(απd^2)/1440 (r^2=d^2/4)
α=1440A/(πd^2)
s=απd/360 (where s=arc length) so
s=(1440Aπd)/(360πd^2)
s=4A/d and since A=10mi^2 and d=20mi
s=(4*10)/20
s=2 miles
(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84
Answer:
The answer is $8.00.
Step-by-step explanation:
First, you have to find how much for each app so you have to divide by 3 :
3 apps = $2.40
1 app = $2.40 ÷ 3
1 app = $0.80
Next, you have to multiply it by 10 :
1 app = $0.80
10 apps = $0.80 × 10
10 apps = $8.00
