the building and the ground
form a right angle as shown. Find
the distance between the ground
and the top of the ladder, x, in
feet.
A 20-foot ladder is leaning on a building. The bottom - 1

Answers

Answer 1
Answer:

Answer:

From the bottom of the building to the top of the ladder, it is 16 feet.

Step-by-step explanation:

Depending on what grade you are in, you might know the Pythagorean theorem, whose equation is a^2+b^2=C^2 The measurement of the leaning ladder (20ft) is the hypotenuse of the right triangle, the distance from the bottom of the ladder to the building is the leg length (12ft). With this information we know the "c" of the equation, and the "b" or "a" of the equation. If we plug in the number for the letter the equation will look like this:  

12^2+b=20^2. 20 to the second power is 400, and 12 to the second power is 144. You can use the subtraction property of equality and get b^2=256. Use can use a calculator for this part. The square root of 256 is 16, which leaves the equation with b=16

What is the solution to 5x−2=13 ? Plot the solution on the number line.

Answers

Answer:

x= 3

Step-by-step explanation:

5x-2=13 - Add 2 to both sides which cancels out the -2 and turns 13 into 15

5x=15 - Divide 5 on both sides which cancels the 5 and leaves x=3

x=3 - Is the final answer or the solution to the problem

1. 3 x 2 = 6  2/3 x 2 = 4/3 which is 1 whole and 1/3 so the answer is 6 + 1 1/3 = 7 1/3
2. 3 1/2 x 4 1/7 = 58
3. 1/6 x 4 you only times the first number so 4/6 which is simplified is 2/3
4. 
5. 4 -:- 2 = 2 2/7 you only divide the first number (the 2 which makes it 1/7)

U^-3=1/125
U=?

Answers

a^(-n)=(1)/(a^3)\n-----------------------\n\nU^(-3)=(1)/(U^3)\n\ntherefore\n\n(1)/(U^3)=(1)/(125)\ \ \ \ \ |inverse\ both\ sides\n\nU^3=125\n\nU=\sqrt[3]{125}\n\n\boxed{U=5}\ because\ 5^3=125
the answer is: U =5

first, you take the U^-3 and put it as 1/U^3, that is because you cannot have a negative exponent, you MUST turn the exponent into a positive....
now you have 1/U^3 = 1/125...     now you find the uncubed version of 125::::::

the cube root of 125 is 5

so, when you have U^-3, you are looking at 5^-3..
