Answer:
You will put 1220.83ft³ of water in the pool
Step-by-step explanation:
radius = half of diameter
d = 18ft
r = 18ft / 2 = 9ft
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 6ft
π = 3.14
r = radius = 9ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (9ft)²) * 6ft
v = (3.14 * 81ft²) * 6ft
v = 254.34ft² * 6ft
v = 1526.04ft³
The volume of the cylinder is 1526.04ft³
If it is filled to 80% then we have to multiply the volume by 80/100
1526.04ft³ * 80/100 = 1220.83ft³
You will put 1220.83ft³ of water in the pool
Answer:
The probability of randomly picking a red candy is 1/20 and In percentage value 5%
Step-by-step explanation:
There are 5 blue candies, 6 red candies, and 9 yellow candies.
Now, Total
5 + 6 + 9 = 20 candies
Now, The probability of randomly picking a red candy is 1/20
Now, In percentage
1/20 × 100% = 5%
Thus, The probability of randomly picking a red candy is 1/20 and In percentage value 5%.

Answer:
BC = 15
Step-by-step explanation:
Because of parallel lines, AD and BE, triangles ADC and BEC are similar.
In similar triangles, the lengths of corresponding sides are proportional.
AC/BC = DC/EC
We see that AC = AB + BC = 3 + BC
Also, DC = DE + EC = 2 + 10 = 12
(3 + BC)/BC = 12/10
(3 + BC)/BC = 6/5
Cross multiply.
5(3 + BC) = 6BC
15 + 5BC = 6BC
15 = BC
BC = 15
Answer:
<u><em>y = 3x - 3</em></u>
Given:
y = 3x - 4
through (2, 3)
To Find:
equation of the line parallel to y = 3x - 4 through the given point (2, -3)
Step-by-step explanation:
y = mx + b
The line is parallel, so the slope is the same
y = 3x + b
Plug in the x and y values of your point
-3 = 3(2) + b
Solve for 'b'
-3 = 6 + b
0 = b + 3
b = -3
Your final equation is,
y = 3x - 3
You can use proportions to find the answer.
20/100=?/11.95
20*11.95=239
239/100=2.39
So the discount takes $2.39 off of the original price.
11.95-2.39=9.56
7/100=?/9.56
7*9.56=66.92
66.93/100=0.6692
Round to nearest tenth: 0.67
9.56+0.67=10.23
The final cost of the CD is $10.23
