Answer:

The height of the cylinder 'h' = 12 inches

Step-by-step explanation:

Explanation:-

Given Volume of the cylinder = 8,478 cubic inches

Radius of the cylinder = 15 inches

Volume of the cylinder is determined by

                                  [tex]V = \pi r^{2} h[/tex]

                           8,478 = 3.14 × (15)² h

                         [tex]h = \frac{8478}{3.14 X 225} = 12 inches[/tex]

The height of the cylinder 'h' = 12 inches

Answer:

h=189

Step-by-step explanation:

solve for H by simplifying both sides of the equation, then isolating the variable.

Answer:

1.6

Step-by-step explanation:

to find the slope, find two points on the line in the graph.

i'll be using (-1, 4) and (4, -4).

substitute the points into the rise over run equation.

[tex]\frac{rise}{run} = \frac{y1-y2}{x1-x2} =\frac{-4-4}{-1-4}[/tex]

solve the fraction by subtracting first. always remember to subtract the values.

[tex]\frac{-4-4}{-1-4}=[/tex] 1.6

Answer:

The answer is 1 3/8 (D)

Step-by-step explanation:

If you added the amounts of each tick mark (which would be 13 2/8), and then subtracted it by 16, it would be 2 6/8. 2 6/8 divided by two (because we need to find the length of both of the indentical meteors) would be 1 3/8.

Now, to make sure it is 1 3/8: 13 2/8 + 1 3/8 + 1 3/8 = 16.

It is confirmed, 1 3/8 (Answer D) is the correct answer.

Answer:

The value of [tex]\frac{14}{8} + \frac{15}{12}[/tex]  = 3

Step-by-step explanation:

Explanation

Given       [tex]\frac{14}{8} + \frac{15}{12}[/tex]

L.C.M     8 , 12   is  24

       [tex]\frac{14}{8} + \frac{15}{12} = \frac{14 X 3 + 15 X 2}{24}[/tex]

                  = [tex]\frac{42 +30}{24} = \frac{72}{24} = 3[/tex]

Final answer:-

The value of [tex]\frac{14}{8} + \frac{15}{12}[/tex]  = 3

Answer:

False

Step-by-step explanation:

a+(-a)=a-a = 0 which means irrational numbers are not closed under addition or subtraction.

False. Irrational numbers are not closed under subtraction.

Given data:

Closure under subtraction means that if you subtract two irrational numbers, the result will always be another irrational number.

However, this is not true for irrational numbers.

For example, consider the irrational numbers √2 and √2 + √2. Both of these numbers are irrational. However, when we subtract √2 from √2 + √2, we get:

(√2 + √2) - √2 = √2

The result, √2, is still an irrational number. But if we subtract two irrational numbers like √2 from √2, we get:

√2 - √2 = 0

The result, 0, is a rational number, not an irrational number.

Answer:

21.5≤μ≤25.2

Step-by-step explanation:

The formula for calculating confidence interval is expressed as;

CI = xbar±(z*s/√n)

xbar is the mean = 23.7

s is the standard deviation= 16.3

n is the sample size = 438

z is the z score at 95% confidence level

z = 1.96

Substitute into the formula

CI = 23.7±(1.96×16.3/√438)

CI = 23.7±(1.96×16.3/20.93)

CI = 23.7±(1.96×0.77788)

CI = 23.7±1.5264

CI = (23.7-1.5264, 23.7+1.5264)

CI = (21.4736, 25.2264)

The confidence interval to the nearest tenth is 21.5≤μ≤25.2

Step-by-step explanation:

the decay factor for the given decay rate is 0.999

Given :

In recent years, Japan's population has been declining at a rate of 0.1% per year.

we need to find the decay factor for the given exponential rate.

The rate of decay is 0.1%. To remove percentage we divide by 100

so , [tex]\frac{0.1}{100}=0.001[/tex]

The decay rate is 0.001

To find out decay factor , we subtract decay rate from 1

decay factor is 1- decay rate

Decay factor is 1-0.001=0.999

So the decay factor for the given decay rate is 0.999

Answer:

Step-by-step explanation:

Answer:

8x + 20

Step-by-step explanation:

Side = 2x + 5

Perimeter of square = 4*side

                                 = 4*(2x + 5)          {Use distributive rule:a(b +c) = a*b +a*c}

                                = 4*2x + 4*5

                                = 8x + 20

Answer:

50

Step-by-step explanation:

lxb=144

16xb=144

b=9

perimeter=2(l+b)

=2(16+9)

=50 cm

Answer: 50cm squared

Step-by-step explanation:

First we need to find the side lengths,

In order to find the area you do,

A = Length x height

we know that the area is 144 and the length is 16.

144=16 x height

144 = 16 x ?

So know we need to find the height, so we do 144/16= 9

so the height 9 cm.

The question is not asking for the height, but the peremeter.

Peremeter = (Length x 2) + (height x 2)

peremeter= 16 x 2 + 9 x 2

peremeter = 32+18

peremeter = 50 cm squared

so the peremeter is 50 cm squared.
