[tex]\frac{35}{18}[/tex] π m

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{50}{360}[/tex] ( r is the radius )

     = 2π × 7 × [tex]\frac{5}{36}[/tex]

Answer:

x = -7

Step-by-step explanation:

-42=-7+5x

-42 + 7 = 5x

5x = - 35

x = -35/5

x = - 7

Hope it helps!

Answer:

x = -7

Step-by-step explanation:

Given equation:

[tex]-42 = -7 + 5x[/tex]

Simplify the equation.

        [tex]-42 = 5x -7[/tex]

    2. Flip the equation.

        [tex]5x + 7 = -42[/tex]

    3. Add 7 to each side.

        [tex]5x - 7 + 7 = -42 + 7[/tex]

        [tex]5x = -35[/tex]

    4. Divide both sides by 5.

        [tex]\frac{5x}{5}[/tex] = [tex]\frac{-35}{5}[/tex]

    5. Divide the fraction.

        [tex]-35[/tex] ÷ [tex]5[/tex] = [tex]-7[/tex]

Answers

Answer: B and C

Step-by-step explanation: To start off, you subtract 3 from both sides, to get 4<z/2, then multiply both sides by 2, you get z>8. Now it's greater than 8, so it can't equal 8, so the answers would be B and C, since they are both greater than 8, and you have to select multiple choices.

Answers

Answer: C

Work:

1) Change the Mixed number into an improper fraction
3 x 8 = 24
1+24 = 25/3

2) Get both fractions on equal terms. Find the Greatest Common Denominator. In this case, it’s 24. Multiply by what you need to get 24. 8x3=24 and 12x2=24

3) Multiply Accordingly
25/8 x 3 = 75/24
7/12 x 2 = 14/24

4) Subtract and change back to Mixed Number
75-14 = 61
61/24 = 2 13/24

If a fair die is rolled once, what is the probability of one
An odd number
A number greater than 2
A square number?​

Answers

Answer:

A fair die has 6 sides.

There are 3 odd numbers on a fair die so the probability would be 3/6

There are 4 numbers greater than 2 on a fair die o the probability of that would be 4/6

There is only one number that will make it square and that is 4. So the probability would be 1/6

6(y−8z+7)

Answers

Answer:

6y - 48z + 42

Step-by-step explanation:

6 ( y - 8z + 7 )

= 6y - 48z + 42

first you would distribute:

so you distribute the 6

so it’d be 6 x y which is 6y

6 x -8z which is -48z

6 x 7 which is 42

put it together

final answer: 6y-48z+42

Step-by-step explanation:

Answer:

8:48

5:25

21:35

Step-by-step explanation:

for any ratio, it stays the same if you multiply left and right with the same number.

So let's take the last one:  

3 : 5 should be equivalent to ? : 35

How did 5 get to be 35? It was multiplied by 7.

So we do that on the left side as well.

3×7 = 21.

Conclusion: 21:35 is equivalent to 3:5

Given that g(x) = −2x+20, find g(−3).

Answers

Answer: 26

Step-by-step explanation:

Okay, so... The new equation would be -2(-3)+20...

So follow the rule of PEMDAS, PEMDAS is;

Parentheses

Exponents

Multiplication

Division

Adding

and Subtracting

Since there are no equations in parentheses and no exponents, we start with multiplication. Which would be -2(-3). ANY parenthesized number beside another number means you must multiply them.

-2(-3) = 6 because a negative multiplied by a negative is a positive..

Now we have 6 + 20 which is 26, so 26 is your answer.
