Answer:
D
Step-by-step explanation:
Given y varies directly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = when x = 1 and z = 4 , then
= k × 1 × 4 = 4k ( divide both sides by 4 )
= k
y = xz ← equation of variation
When x = 6 and z = 3 , then
y = × 6 × 3 =
× 18 = 2 × 6 = 12
Answer:
180
Step-by-step explanation:
1. Write a proportion.
=
2. Cross multiply.
6x60=360
360/2=180
x=180
OR
1. Write a proportion.
=
If you look at the bottom, since 2 times 30 is 60, 6 times 30 is 180, making the fractions equal.
Answer:
Radius = 2.90 cm
Step-by-step explanation:
220 = 3.14 × {r}^{2} × 8.3
220 = 26.062 × {r}^{2}
220/26.062 = {r}^{2}
{r}^{2} = 8.44 ( approx )
r = √8.44
r = 2.90 cm. (approx)
