Answer:
r = ∛3V/4π
Step-by-step explanation:
v = 4/3 πr³
4πr³ = 3V
r³ = 3V/4π
r = ∛3V/4π

Answer:
y = 17(7) + 6
Step-by-step explanation:
Given that:
Amount owed = $125
Payment per week = $7
Number of whole weeks to pay :
$125 / $7 = 17.85 = 17 whole weeks
$125 - (17 * 7) = $125 - $119 = $6
Using slope intercept notation :
y = mx + c
Where m = slope ; c = intercept. ;
m = 17,; x = $7, c = $6
y = 17(7) + 6
1) 33+a=12a
33 = 11a
33/11 = a
a = 3
2) <span>-6n+2=4n-5
</span>2 = 10n-5
7=10n
n = 7/10
n = 0,7

b = 22.4/1.4
b = 16
