Answer:
449 per hour
Step-by-step explanation:
First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.
First:
Know there are 60 minutes in one hour
Second:
Take 7.48 and multiply it by 60
Third:
This should give you---448.8
Which is correct, but we are not done
Fourth:
Round to the nearest whole number
448.8
8 is closer to 10 than it is to 1 so we add 0.2
Which gives us 449
Five:
Just add the "per hour"
Six:
Your answer is---449 per hour---
SSS congruence rule.
Solution:
Given ΔABC and ΔDEF are congruent.
To prove that on which rule they are congruence.
In triangle ABC,
AB = 2.5 cm, BC = 1.8 cm, CA = 1.8 cm
In triangle DEF,
DE = 2.5 cm, EF = 1.8 cm, FD = 1.8 cm
Consider ΔABC and ΔDEF,
AB = DE (Side)
BC = EF (Side)
CA = FD (Side)
∴ ΔABC ≅ ΔDEF (by SSS congruence rule)
Hence, the given triangles are congruent by SSS congruence rule.
(-2.5,1.5) should be the answer

Answer: Choice D</h3>
Explanation:
For now, let's ignore the blue curve.
If we kept the red curve completely fixed in place, and only moved the xy axis, then we can move the xy axis 5 units to the right to give the illusion the red curve is moving (even though it's fixed in place).
Moving the xy axis 5 units to the right means each x input is 5 units larger. So x jumps up to x+5
In other words, going from f(x) to f(x+5) will shift the f(x) curve 5 units to the left. So that's why we go from x^2 to (x+5)^2 which is what choice D shows.
