Answer:
The discounted price is $9.90.
Step-by-step explanation:
First, you need to find the amount of 45%.
Step 1- Convert the percent to a decimal.
Step 2- Multiply.
0.45×18= 8.10
Step 3- Subtract.
18-8.10= 9.90
So, the discounted price would be $9.90.
After 3 seconds it's been descending for 3 seconds at a rate of 2 feet per second. So it's gone down 6 feet, and now it's at a height of 67. So it started off at 73.
<span>Its height after x seconds is 73 - 2x. (73 to start off with, minus 2 feet per second that's passed.) </span>
<span>After 8 seconds it will be at a height of 73 - 2*8 = 73 - 16 = 57.</span>

if you divide the answer althrough by 2 you should get the above equation
Answer:
First dimension= 12ft Second dimension= 12×2.5=30ft
Step-by-step explanation:
From the question, I was able to deduce that the swimming pool is a cuboid, and the formula for finding the volume of a cuboid is Length×Breadth×Height.
let the first dimension be the length and the second dimension be the breadth.
Therefore, the length=L , Breadth= 2.5×L= 2.5L and Height= 8ft. L×2.5L×8 = 2880 cubic feet.
2.5L²×8= 2880 cubic feet. Therefore, L²= 2880/(2.5×8)=144. L²=144. L=√144. L=12ft. and breadth= 2.5×Length= 2.5×12ft=30ft.
In a nutshell the first dimension is 12ft, and the second is 30ft.
Answer:
- 0.125
Step-by-step explanation:
Given the equation :
(0.020(5/4) + 3 ((1/5) – (1/4)))
0.020(5/4) = 0.025
3((1/5) - (1/4)) = 3(1/5 - 1/4) = 3(-0.05) = - 0.15
0.025 + - 0.15 = 0.025 - 0.15 = - 0.125
