120 - 86.4 = 33.6
The new rectangle which is 72% shorter is 21.6 centimeters.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given The original rectangle is 120 centimeters.
And the new rectangle is 72% shorter or (100 - 72)% = 18% of the original rectangle which is,

What is the volume of a cone with a diameter of 8 in and a height of 5 in?
Answer:
V=80π/3 or V=83.78
Step-by-step explanation:
The volume is
V=πr^2h/3
r=4 (because the radius is half the diameter)
h=5
V=π16*5/3
V=80π/3
Answer:
83.73
Step-by-step explanation:
volume = (1/3) · π · r2 · h
volume = (1/3) x 3.14 x 4^2 x 5
volume = (1/3) x 3.14 x 16 x 5
3.14 x 16 x 5 = 251.2
1/3 x 251.2
83.73

Write an equation describing the relationship of the given variables. y varies inversely as the cube root of x and when x=125, y=8.
Answer:
y = 40 / x^1/3
Step-by-step explanation:
Given that :
y α x^1/3
y = k * 1 / x^1/3
y = k / x^1/3
When x = 125 ; y = 8
8 = k / 125^1/3
Cube root of 125 = 5
8 = k / 5
8 * 5 = k ; k = 40
Hence, expression becomes :
y = 40 / x^1/3
y α k/∛x is the relationship of the variables x and y whose values are 125 and 8.
What is Equation?Two or more expressions connected with an equal sign is called Equation.
The relationship of the given variables. y varies inversely as the cube root of x.
By given data we can write as
y α k/∛x
The cube root of 125 is 5.
y α k/∛125
y α k/5
8=k/5
k=40
Hence y α 40/∛x is the relationship of the variables x and y whose values are 125 and 8.

select all the numbers between 80 and 100 that have exactly 4 factors, one of which is 5.
80
85
90
95
100
Answer:
90.
Step-by-step explanation:
Here 5 is one of the 4 prime factors, so dividing the lower (80) and upper limit (100) by 5 we have new lower limit 16 and new upper limit 20.
So the product of other 3 factors should be greater than 16 and less than 20. And we can have it from 18 only. Hence the number is 90.
The numbers between 80 and 100 having factor 5 are
80, 85, 90, 95, 100
16 = [tex]2^{4}[/tex]
17 = 17
18 = 2× 3 × 3
19 = 19
20 = [tex]2^{2}[/tex] × 5
90 = 2 × [tex]3^{2}[/tex] × 5

Cynthia invests some money in a bank which pays
5% compound interest per year.
She wants it to be worth over £8000 at the end of 3
years.
What is the smallest amount, to the nearest pound, she can invest?
Answer:
£6911 is the smallest amount Cynthia should invest to get £8000 after three years
Step-by-step explanation:
lets Assume that amount needs to invested for three years = £ x Rate of Interest = R = 5% per year Duration in years = n = 3 year
Amount expected after three years when compounded annually = A = £8000 Formula for Amount of compound interest annually is a follows A = P( 1 + R/100)^n In our case Principal P = x , Amount A = 8000 , R = 5% and n = 3( since compounded annually). On substituting these values in above formula we get 8000 = x ( 1 + 5/100)^3 ⇒8000 = x ( 105/100)^3 ⇒8000 = x ( 21/20 )^3 ⇒(8000 × 20 × 20 × 20)/(21×21×21) = x ⇒x = 6910.70≈6911
Hence £6911 is the smallest amount Cynthia should invest to get £8000 after three years
