Answer:

a) 23.0769% increase

b) 9.375% decrease

Step-by-step explanation:

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

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

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.

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.

Answer:

33.6 cm

Step-by-step explanation:

120 x 0.72 = 86.4

120 - 86.4 = 33.6

The new rectangle which is 72% shorter is 21.6 centimeters.

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,

= (18/100)×120 centimeters.

= 21.6 centimeters.

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14
