Answer:
I'm going to use the Pythagoras theorem
1. hypotenus²= base²+height²
h²=80²+18²
h²=6400+324
√h²=√6724
hypotenuse= 82
2. 53²=45²+h²
2809=2025+h²
2809-2025=h²
784=h²
√784=√h²
h=28
3. 40²=b²+24²
1600=b²+576
1600-576=b²
√1024=√b²
b= 32
P = IRT
T=P/(IR)
hope helped
Answer: y=3/4x + 1/2
Step-by-step explanation: Parallel lines must have the same slope, so you already know the equation must be something like y=3/4x+b. You are given a point that the line goes thru(2,2), so you can plug this point into the equation to solve for b.
(2)=3/4(2) + b
2=6/4 + b
2= 3/2 + b
b= 2-3/2
b=4/2- 3/2
b=1/2
so y=3/4x + 1/2
So knowing that the tank holds 570 liters of water, we would divide the amount of liters per gallon which is 3.8.
570 / 3.8 = 150 gallons of water.
I hope this helps :)
