ANSWER
The ratio in the simplified form is
80:3
EXPLANATION
We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.
We obtain the ratio as follows:
This is the same as
We multiply each term in the ratio by 4 to obtain;
This gives us,
Answer:
about 1.4 hours
Step-by-step explanation:
3.13 gallons per minute.
60 minutes in an hour, so multiply both numbers by 60.
187.8 gallons per hour.
Divide the number of gallons we need to fill the tub the number of gallons put in per hour.
255÷187.8=1.375...
Round it, you get 1.4 hours.
It takes about 1.4 hours to fill the hot tub.
Vertex form: y = a(x - h)² + k
h = 2
k = -1
y = 0
x = 5
0 = a(5 - 2)² - 1
0 = 9a - 1
a = 1/9
This question has to do with making an approximation based on the diagram of the angle. Angle KLM is an obtuse angle meaning it is larger then 90° but is also less than 180°. The only choices that lie within this range are choices B and D. However, it is safe to assume that angle KLM is closer to 180° than to 90° based on the diagram, therefore the answer must be choice B.
I hope this helps.
