Answer:

16 feet

Step-by-step explanation:

This ladder and building creates a right triangle with 34 as the hypotenuse and 30 as a side. the Pythagorean theorem says that a^2 + b^2 = c^2 so 900 + b^2 = 1156. b^2 = 256, square root both sides and you get b = 16

Answer:

16 feet

Step-by-step explanation:

use Pythagorean theorem

a^2 + b^2 = c^2

a^2 + 30^2 = 34^2

a^2 + 900 = 1156

move 900 to the right to leave the a variable by itself

a^2 = 256

take the square root of both sides

a = 16

You spin the spinner once.<br> 6<br> 8<br> 17<br> What is P(prime)?<br> Options: 33% 25% 26% or 36%
SIZIF [17.4K]

Given:

You spin the spinner once.

The possibilities are 6, 8, 17.

To find:

The probability of getting a prime number, i.e., P(prime).

Solution:

In the given numbers 6, 8, 17, only 17 is a prime number because it is divisible by 1 and itself.

6 and 8 are divisible by 2, so they are not prime.

The probability (in %) of getting a prime number is:

P(\text{prime})=\dfrac{\text{Prime numbers}}{\text{Total numbers}}\times 100

P(\text{prime})=\dfrac{1}{3}\times 100

P(\text{prime})=33.33\%

P(\text{prime})\approx 33\%

Therefore, the correct option is A.

-8-x= x - 4x<br> Can u help me know the answer please and I need to show my work
marin [14]

Answer:

x= -4

Step-by-step explanation:

-8 -x= x -4x

Simplify:

- 8 - x =  - 3x

Bring all x terms to 1 side by adding x on both sides:

- 8 =  - 3x + x

Simplify:

- 8 =  - 2x \\  - 2x = 8

Divide both sides by -2:

x =  \frac{8}{ - 2}  \\ x =  - 4
