Answer:

≈ 660.5 in²

Step-by-step explanation:

The surface area (A) of a sphere is calculated using the formula

A = 4πr² ← r is the radius

Given diameter = 14. 5 then radius = 7.25, thus

A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²

2 is 10 times 0.02. true or false

wlad13 [49]

False: 10 • 0.02=
when anything is multiplied by two, move a decimal once to the right~ if it is a whole number, add a zero.
0.02-> move one decimal to the right= 0.2
Therefore, 2 is not equal to 10 • 0.02
10 • 0.02= 0.2
BUT 10 • 0.2= 2

Write the equation of the line that passes through the points (-8,-1) and (5,-7). Put your answer in fully reduced point-slope f

alexandr402 [8]

Answer:

The answer to the question provided is:

$y + 1 = - \frac{6}{13} (x + 8)$

Step-by-step explanation:

❃Incase you forgot what the point-slope formula is ☟

$y - y_1 = m(x - x_1)$

❃Incase you also forgot, what the slope formula is ☟

$m = \frac{y_2 - y_1}{x_2 - x_1}$

➊ First: We are going to be solving for the slope.

$m = \frac{ - 7 - ( - 1)}{5 - ( - 8)} = \frac{ - 6}{ \: 13} = - \frac{6}{13}$

➋Second: Plug in.

$y + 1 = - \frac{6}{13} (x + 8)$

The perimeter of a rectangle is 1144 ft. It’s length is three times it’s width.find the dimensions of the rectangle.

AVprozaik [17]

Answer:

$Length= 429 feet\\Width=143feet$

Step-by-step explanation:

Perimeter of the rectangle= 1144 feet

Length=3*Width

L=3*W

Perimeter of rectangle:

$2(Length+Width)\\\\ 1144=2(3W+W)\\\\ 1144/2=3W+W\\\\ 572=4W\\\\ W=572/4\\\\ W= 143 feet\\\\Width=143 feet\\\\Length=3*143=429 feet\\\\$

The Dimension of the rectangle is :

$Length= 429 feet\\Width=143feet$

812,000 gallons of water in an olympic training center's pool. express this number in scientific notation.

frez [133]

8.12×10^5
... i got this by taking the first number 8 and then counting the places behind the 8 which would be 5 so than you move the decimal place by 5 so you get 8.12 then you show theirs 5 places behind the 8 by adding the 10^5 so youbget 8.12×10^5
