Your answer is the 3rd option.
![c = \pi \times d](https://tex.z-dn.net/?f=c%20%3D%20%5Cpi%20%5Ctimes%20d)
You must divide by π on both sides, therefore d=c/π
4 years=48 months
A new car costs 25,000, but she will get 13,000 for her used car as long as she takes good car of it. If she takes good care of her used car and gets 13,000 for it, she will only need to save 12,000 total. We can divide 12,000 by 48 to find out how much Courtney should save minimum each month to afford her new car. 12,000/48=250
You can check to see if this is correct by multiplying 48*250=12,000. Paying 250 for each month of the 48 months will equal the $12,000 that Courtney needs.
Courtney needs to save at least $250 per month to afford her new car in 4 years.
I hope this helps :)
Answer:
Surface area - 0.96, Volume - 0.064
Step-by-step explanation:
2/5- 0.40
For surface area, the equation is 6a^2
When you fill in the variable its
6(0.4)^2
follow pemdas, so you do the exponents first
(0.4)(0.4)
0.16
6(0.16)
0.96
The formula for volume is a^3
0.4^3
(0.4)(0.4)(0.4)
(0.16)(0.4)
0.064
Answer:
108 cm²
Step-by-step explanation:
The formula for the lateral area of a pyramid such as this is ...
LA = 1/2Ps
where P is the perimeter of the base (6·3 cm = 18 cm) and s is the slant height (12 cm). Putting the given values into the formula gives ...
A = 1/2·(18 cm)·(12 cm) = 108 cm²
___
The formula gives the total area of the 6 triangular faces. Each face has an area of ...
A = 1/2·b·h = (1/2)(3 cm)(12 cm) = 18 cm²
Then the total area of the six triangles is ...
6 · 18 cm² = 108 cm²
Answer: x=20/3=6.67
Step-by-step explanation:
To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.
-----------------------------------------------------------------------------
Given
x:10=9:6
Cross Multiply
9·x=6·10
9x=60
Divide 9 on both sides
9x/9=60/9
x=20/3=6.67
Hope this helps!! :)
