Samantha is trying to determine how she can save money by cutting her electricity bill. She is currently on a standard use plan

for electricity and pays 8.5 cents per kWh. She keeps track of when she uses electricity and is thinking about switching to an interval use plan for electricity which costs 2 cents per kWh for off-peak use and 13 cents per kWh for on-peak use. Off-peak hours are from 8PM - 8AM and on-peak hours are from 8AM - 8PM. Below is the chart of her electricity usage:
Samantha’s Electricity Usage Per Month
1100 kWh between 8PM and 8AM
800 kWh between 8AM and 8PM

Explain and justify which plan would best suit her needs.
a.
Samantha should not switch to the interval use plan, which would cost $126.00 more per month.
b.
Samantha should switch to the interval use plan, which would save her $126.00 per month.
c.
Samantha should switch to the interval use plan, which would save her $35.50 per month.
d.
Samantha should not switch to the interval use plan, which would cost $35.50 more per month.

An investment of 100,000 AED increases at a rate of 16% per year. What is
stepan [7]

Answer:

1,946,075.95 AED

Step-by-step explanation:

Firstly, we write the general formula for an exponential increase as follows;

V(t) = A( 1 + r)^t

where V(t) is the value after some number of years t

A is the investment amount which is 100,000 AED

r is the rate of increase which is 16% = 16/100 = 0.16

t is the number of years which is 20

substituting these values;

V(20) = 100,000( 1 + 0.16)^20

V(20) = 100,000(1.16)^20

V(20) = 1,946,075.95 AED

The millers are going to put a pool in their backyard this summer. The pool will have a depth of 5 feet, and the dimensions show
erica [24]

Answer:

D : 510 units

Step-by-step explanation:

NOTE:

Something to consider when solving problems like this is to break the large shape down into smaller, more managable shapes. So for this problem, you can break down this irregular shape into two rectangles. This will make solving problems similar to this easier in the future :)

WORK:

I broke down this shape into two rectangles with the following dimensions:

- 12 meters by 5 meters

- 3 meters by 14 meters

You also know that the depth has to be 5 feet (the problem itself did not account for differences in feet and meters, as when I converted the 5 feet to meters and solved that way, none of the answers were correct)

Using this information, you can now solve for the volume of each of the rectangles

12*5*5 = 300 units

3*14*5 = 210 units

Then, you simply add the two volumes together to find the total volume needed to fill the pool which equals

510 units
