Gekata [30.6K]

Answer:

$x=20$

Step-by-step explanation:

Since angle RTS is a right angle, we have three similar triangles.

you are building a rectangular wading pool you want the area of the bottom to be 90 ft squared you want the length of the pool t

Sindrei [870]

L=2W+3, A=LW, using L from the first in the second gives you:

A=(2W+3)W

A=2W^2+3W, and we are told A=90 so

2W^2+3W=90

2W^2+3W-90=0

2W^2-12W+15W-90=0

2W(W-6)+15(W-6)=0

(2W+15)(W-6)=0, since W>0 for all real possibilities,

W=6ft, and since L=2W+3

L=15ft

So the pool will be 6 ft wide by 15 ft long.

Find the probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events. Hint:

emmainna [20.7K]

Answer:

0.037

Step-by-step explanation:

If the hitter makes an out 72% of the time, then the probabilty that he makes hit in 1 at-bat is $p=0.72$ and the probabilty that he doesn't make hit in 1 at-bat is $q=1-p=1-0.72=0.28.$
