Pedro spent 2 1/5 hours on his math homework and half as long on his science homework one weekend. If his English and social stu
Flura [38]

2 1/5 hours on homework for math = 2.2

Science homework took 1.1 hours to complete.

2.2+1.1= 3.3

7/8 of an hour is 50 minutes because we know that an hour is 60 minutes and every 10 minutes is a number for the numerator, if that makes sense.

3.3 of an hour plus 50 minutes, would equal 3.8 since the 3 after the point would be minutes. To convert into hours, since an hour is 60 minutes, we have 4 hours and 20 minutes he spent on homework over the weekend. That would be your answer! Hope this helped.

you have $120 to donate equally to several charities. Does this situaton represent direct or inverse variation? Explain.
SOVA2 [1]
This situation represents inverse variation.

The difference between direct and inverse variation is in direct variation, as one variable goes up the other does too, while in inverse, as one variable goes up the other falls.

In this case, as you donate to more charities, the amount you donate to each charity falls, because you donate an equal amount. This means it's inverse variation.

Hope this helps!

What is the center of MN given M(3, -1) and N(7,-5)
Neko [114]

Answer:

(5, -3)

Step-by-step explanation:

So the center of the two points, or a line can be defined using the equation: midpoint=(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}). So using the two points you gave, you simply plug the values in to get

midpoint=(\frac{3+7}{2}, \frac{-1+(-5)}{2})\\

Add numerators:

midpoint=(\frac{10}{2}, \frac{-6}{2})

Simplify fraction:

midpoint=(5, -3)
