Identify the dependent and independent variables in the situation. match:

independent variable
dependent variable

a. temperature
b. amount of electricity used

Step-by-step explanation:

Depending on where you live, you really can't tell what causes the amount of electricity to be used. But it is the dependent variable. In our area (northern Canada), there is no doubt about it being the dependent variable and the reason that it is.

-30 degrees Centigrade is going to require an awful lot of fuel to get house temperatures that are comfortable. Few people use air conditioning in the summer, but a bad summer has really long hot days unknown to people in the south. They are surprised at the length of our days and how hot the house temperatures are.

dependent variable: amount electricity used.

independent variable: temperature.

The amount of electricity used depends on the temperature, summer or winter.

for the points! : )

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
