Write an expression for the amount she added:
Dimes: 2(0.10)
Quarters: 3(0.25)
Nickels: 6(0.05)
Now write an expression for what she took out:
Quarters: 2(0.25)
Dimes: 5(0.10)
Now combine them:
2(0.10) + 3(0.25) + 6(0.05) - 2(0.25) - 5(0.10)
Simplify:
0.20 + 0.75 + 0.30 - 0.50 - 0.50
1.25 - 1.00 = 0.25 increase.
An equilateral triangle sides are all equal to each other. This means that is one side of an equilateral triangle is x + 3 then the sides of the other two triangles as also each x + 3
The formula for perimeter of a triangle is:
Perimeter = side 1 + side 2 + side 3
Or in the case of an equilateral triangle it would be:
Perimeter = 3(side)
This means that for the formula of this equilateral triangle you have:
Perimeter = 3(x + 3)
If asked the three out side of the parentheses can be distributed, meaning that you multiply the outside number (in this case that is 3) to all the number inside the parentheses (in this case that is x and 3)
Perimeter = (3 * x) + (3*3)
Perimeter = 3x + 9
Both of these are correct:
P = 3(x + 3)
P = 3x + 9
Hope this helped!

You have 300 which changes to 200
if it was 300 to 150 that would be 50%
since 150/300=1/2
take 200/300=2/3 so about 66%
If it descends, it means it goes down/ decreases. so 90-105, will get you to negative 15 (-15)
Step-by-step explanation:
A can is a cylinder.
Volume of a can = Volume of Cylinder
Given Radius = 3.2 inches and height = 15 inches,
Volume of one olive oil can =
Volume of 5 olive oil cans = 5 x volume of one olive can
I will just leave the answer in terms of pi as I'm not sure if you need to round off your answers.
