How do you get 60cm2 in question 1?

Mathematics
1 answer:
Salsk061 [2.6K]3 years ago
7 0

Answer:

Step-by-step explanation:

4*2=8, thats one rectangle (side)

8*2 is 16, thats TWO rectangles (sides)

7*4=28, thats one rectangle (front)

28*2=56, thats TWO rectangles (front and back)

7*2=14, thats one rectangle (top)

14*2=28, thats TWO rectangles (top and bottom)

add all of these surface areas together

TWO rectangles + TWO rectangles + TWO rectangles

28+56+16=100

As you can see, the 60cm2 is incorrect. 100cm2 is the real surface area of the shape

Write 65% as a fraction in simplest form.​
rusak2 [61]

Answer:

13/20

Step-by-step explanation:

This is actually pretty simple. I had trouble with this for the longest time but it makes sense to me now. A number that is a percent is equal to that number over 100.

65%=65/100

Then all you have to do is simplify! (yaaay)

65/100=<u>13/20</u>

<u></u>

If you need anymore help with this or anything else just let me know!

Divide both sides by -0.5

9=x-7.1

Add 7.1 to both sides

Determine the value of a 10 year old car that costs $24,500 new and depreciates by 9% every year
son4ous [18]
First, we need to know how much the car depreciates each year. Multiply the price of the car by the percentage.

We can turn 9% into a decimal by moving the decimal point two places to the right.

9% = .09

24500 * .09 = 2205

Multiply the product by the amount of years you want to predict the price at.

2205 * 10 = 22050

Subtract that from the original price of the car.

24500 - 22050 = 2450

The value of a 10 year old car that costs $24500 and depreciates 9% every year will cost $2450.
