3/4×1/8 what is the answer

The equation is y = 3x+7. You need to put the y's over the X's that is your slope. Then plug in one of the points of the line and use that to find the y-intercept. Then you just put it into equation form.

Two supplementary angles measure (7x + 11) and (14x + 1)º. What is

ArbitrLikvidat [17]

Answer:

67 degrees (Answer 2)

Step-by-step explanation:

These two angles must sum up to 180 degreess because they are supplementary. Then:

7x + 11 + 14x + 1 = 180, or

21x + 12 = 180, or

21x = 168

Solving for x, we divide both sides by 21. This results in x = 8.

The measure of the smaller angle is 7x + 11, which here is 7(8) + 11 = 67 degrees (Answer 2).

How much water does it take to completely fill a small pool that is 10 feet long, 20 feet wide and 10 feet deep?

irinina [24]

Answer:

2,000 feet cubed

Step-by-step explanation:

To find volume, you use the formula Length x Width x Height. When you plug in the numbers from this equation into that formula you get 10 x 20 x 10. 10 x 20 x 10 = 2,000.

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing

tester [92]

The length of pendulum is 2.485 feet

<h3>Solution:</h3>

Given that,

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth

Therefore, the given formula is:

$T=2\pi \sqrt{\frac{L}{32} }$

We have to find the length of pendulum that makes one full swing in 1.75 seconds

So the modify the given equation to find "L"

$T=2\pi \sqrt{\frac{L}{32} }\\\\ \sqrt{\frac{L}{32} }=\frac{T}{2 \pi}\\\\\text{Taking square root on both sides }\\\\\frac{L}{32} = \frac{T^2}{4 \pi^2}\\\\L = \frac{T^2}{4 \pi^2} \times 32\\\\L = \frac{T^2}{\pi^2 } \times 8$

Substitute T = 1.75 seconds and $\pi = 3.14$

$L = \frac{1.75^2}{3.14 \times 3.14} \times 8\\\\L = \frac{3.0625}{9.8596} \times 8\\\\L = 2.485$

Thus length of pendulum is 2.485 feet approximately

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cyl

mojhsa [17]

The correct equation is:

$216 = \frac{7}{8} \times x - 8$

The volume of second cylinder is 256 centimeter cubed

Solution:

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

$216 = \frac{7}{8} \times x - 8$

$216 = \frac{7x}{8}-8\\\\216 = \frac{7x-64}{8}\\\\7x - 64 = 8 \times 216\\\\7x - 64 = 1728\\\\7x = 1728 + 64\\\\7x = 1792\\\\Divide\ both\ sides\ by\ 7\\\\x = 256$

Thus the volume of second cylinder is 256 centimeter cubed
