The question asks for the unit rate when 1/4 of a kilometer is covered in 1/3 of an hour.
Recall that rate is the quotient of two quantities. In our case the numerator is the distance (1/4) of a kilometer, and the denominator is the time: 1/3 of an hour.
So, we perform the following division of fractions:
1/4 diided by 1/3 which is the same as: 1/4 times 3/1 = 3/4
and since we are asked for the UNIT rate, we do the actual division:
The unit rate is 0.75 km per hour.
Answer:
$4,200
Step-by-step explanation:
4,239 rounds up to 4,240 if you round by tenths but still remains under 4,250. Therefore, it would round down to 4,200.
Answer:
The negative of a negative is a positive. You can rewrite the equation as -3+1. So, the answer is -2.

This is not right 1 is greater than 0
Answer:
Step-by-step explanation:
It's a perfect square.
It factors into (3g - 5h)^2
or (3g - 5h)(3g - 5h)
Make sure it is correctly factored.
3g*3g = 9g^2
3g * - 5h = - 15gh
-5h*3g = - 15gh
5h*5h = 25h^2
These four terms add to 9g^2 - 15gh - 15gh + 25h^2 = 9g^2 - 30gh + 25h^2 which is exactly what you started with.
