Answer:

100

102

Step-by-step explanation:

Let the first even number be 2x

Let the next even number be 2x + 2

1/5 *(2x) + 2/3 (2x + 2) = 88

2/5 *x + 4/3 (x) + 4/3 = 88 Multiply by 15 to get rid of the fractions.

2*3 x + 20x + 20 = 88 * 15

6 x + 20x + 20 = 1320

26x + 20 = 1320

26x = 1300

x = 1300/26

x = 50

2x = 100

2x + 2 = 102

1/5 * 100 = 20

2/3 * 102 = 34*2 = 68

20 + 68 = 88

Answer: see table below

Step-by-step explanation:

$\left\begin{array}{c|l}T&\qquad w(t)\\1&\dfrac{1}{1^2}=1\implies 1.00\\\\2&\dfrac{1}{2^2}=\dfrac{1}{4}\implies 0.25\\\\10&\dfrac{1}{10^2}=\dfrac{1}{100}\implies 0.01\\\\50&\dfrac{1}{50^2}=\dfrac{1}{2500}\implies 0.0004\\\\100&\dfrac{1}{100^2}=\dfrac{1}{10000}\implies 0.0001\\\\200&\dfrac{1}{200^2}=\dfrac{1}{40000}\implies 0.000025\\\\500&\dfrac{1}{500^2}=\dfrac{1}{250000}\implies 0.000004\\\\1000&\dfrac{1}{1000^2}=\dfrac{1}{100000}\implies 0.000001\\\end{array}\right$

Volume? Correct answers please

goldfiish [28.3K]

Answer:

V = 1385.44

Step-by-step explanation:

The equation for volume is V = π r 2 h! Where V = volume, r = radius (half the diameter), and h = height. Now lets substitute what we know into this equation!

Since we are giving the diameter (14) we must divide by 2 to find the radius.

14 ÷ 2 = 7

Radius = 7

Height = 9

V = ?

Time to plug these values in!

V = π $7^{2}$ (9)

We have to distribute pi to 7 square that term and then multiply the value by 9.

V = 1385.44

Hope this Helps! :)
