Answer:
91
Step-by-step explanation:
Rewrite the sides as ratios
s/28=78/24, solve for s
s/28=39/12
s=39/12*28
s=91
Answer:
(x − 3)² + (y − 4)² = 5
Step-by-step explanation:
The equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
First use the distance formula to find the radius:
d² = (x₂ − x₁)² + (y₂ − y₁)²
r² = (2 − 3)² + (6 − 4)²
r² = 1 + 4
r² = 5
Given that (h, k) = (3, 4):
(x − 3)² + (y − 4)² = 5
Answer:
900 minutes
Step-by-step explanation:
1/360 of tub is filled every minute
1/600 of it is drained every minute
1/360-1/600=1/900 is filled every minute then
it takes 900 minutes.
