13). z = ( 9/13)(C)

Solve for C:

Step 1: flip Equation:

9/13 c = z

Step 2: Divide both sides by 9/13

9/13 c/9/13 = z/9/13

C = 13z/9

Answer: Letter Choice, (D), C = 13z/9

12.). Let " h" be the number of hikes:

Expense of First Club:

C * h = 20 + 5h

Expense of Second CluB:

C * h = 7h

20 + 5h < 7h

20 < 2h

h > 10 hikes

Answer: The First Club is Less Expensive, If it is more than Ten Hikes.

14.). Co-Efficient of Friction Formula:

ma = F - mw

+ mw + mw (cancel out +mw)

Mw + ma = F - ma

-ma -ma (Cancel out -ma)

Divide: Both sides by w:

Mw/w = F - ma/w

Therefore, Answer: Letter Choice, (D), M = F - ma/w

Hope that helps!!!! Have a wonderful day!!!! : )

Which of the following is not a true statement about pi?
FinnZ [79.3K]

Answer:

Option D.The ratio of the radius of a circle to its circumference

Step-by-step explanation:

<em>Verify each statement</em>

A) The ratio of the circumference of a circle to its diameter

The statement is True

Because

C=\pi D

so

\pi=C/D

B) Approximated to be 3.14

The statement is True

Because \pi=3.14159265...

C) Approximated to be 22/7

The statement is True

Because

\frac{22}{7}=3.1423

D) The ratio of the radius of a circle to its circumference

The statement is not True

Because

\frac{r}{2\pi r}=\frac{1}{2\pi}

The hypotenuse of a right triangle is 14 centimeters long. One of the legs of the triangle is 6 centimeters. What is the length
BartSMP [9]

Answer: 12.65 cm

Step-by-step explanation:

Use the Pythagoras theorem,

a^2 + b^2= c^2

You are given the hypotenuse , which is c and another leg which is either a or b, does not particularly matter- rearrange to find the missing length

c^2 - b^2 = a^2

14^2 - 6^2 = 160

Square root 160 to find the missing length

12.65

Hope this helped :)

Examine the diagram.
aniked [119]

An outside angle of a triangle is equal to the sum of the two opposite inside angles.

Using the information in the picture, 132 is an outside angle and x and (3x-24) are the two opposite inside angles.

Setting up the equation you would have: 132 = x + (3x-24)

Now solve for x:

132 = x + (3x-24)

Simplify:

132 = 4x -24

Add 24 to both sides:

156 = 4x

Divide both sides by 4:

x = 156/4

x = 39

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.
Fed [463]

Answer:

1. Slope = -4/5

2. Slope = 2/3

3. Slope = 0

4. Slope = 3/-4

5. Slope = 7/-12

6. Slope = 1/2

7. Slope = -2/0 --> Undefined

8. Slope = 3/-2

9. Slope = 5/-4

10. Slope = 4/3

Step-by-step explanation:

Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:

10-2/1-11 = 8/-10 = -4/5
