A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its r

frosja888 [35]

You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds

Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete

Misha Larkins [42]

1. you have to figure out what 3/4 of Ella's time is.
$1 \frac{3}{5} = \frac{8}{5}$
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
$\frac{8}{5} = 8 \div 5 = 1.6$
$\frac{3}{4} = 3 \div 4 = .75$
3. Next you are going to divide 1.6 by .75
$1.6 \div .75 = 2.13$
4. Now multiple 2.13 by 5.
$2.13 \times 5 = 10.65$
Answer is 10
