Answer :

⠀

Step-by-step explanation :

⠀

We know that,

[tex]{\longrightarrow \qquad \frak {\pmb{ 2 \pi r = Circumference_{(circle)} }}}[/tex]

⠀

Here,

⠀

Now, substituting the values :

⠀

[tex]{\longrightarrow \qquad \sf{ 2 \times 3.14 \times r = 122}}[/tex]

⠀

[tex]{\longrightarrow \qquad \sf{ 6.28 \times r = 122}}[/tex]

⠀

[tex]{\longrightarrow \qquad \sf{ r = \dfrac{122}{6.28} }}[/tex]

⠀

[tex]{\longrightarrow \qquad \frak{\pmb{ r = 19.42}}}[/tex]

⠀

Therefore,

Answer:

all students in the club

Step-by-step explanation:

Answer:

C. All students in each grade

Step-by-step explanation:

Answer choices A and B are the worst choices to represent all students in the school. D can also be crossed off because students in the social studies club would most likely have a biased answer. Surveying all students in each grade produces the most random, unbiased results, so C would be the best answer.

Answer:

x = 45°

Step-by-step explanation:

We can tell that "x + 115" and 160° are vertically opposite angles, which means that they are equal. (Refer to image)

⇒ x + 115 = 160

⇒ x = 160 - 115

⇒ x = 45°

12. E  -6x+3

13. R  -6x-12

Step-by-step explanation

You just multiply the number out of the parentheses by each number inside.  If it has a variable, in this case "x" then you just put "x" right after the number.

Example: 2(3x)= 6x

If there is just a negative out of the parentheses then you just change the sign.

Example: -(5x-3)= -5x+3

Answer:

hee-hee

Step-by-step explanation:

We first have to find out how many possible outcomes are in total.

There are 2 outcomes for the coin, either that the coin reads heads or tails.

There are 6 outcomes for the die, from 1 to 6.

2 x 6 = 12

There are 12 possible outcomes.

Now let's move on to the favorable outcomes.

We want to get the coin to flip on either heads or tails, and that the die has a number greater than or equal to 6.

The coin can only flip heads or tails.

The die's sides only goes up to 6.

The probability that the coin reads head and tails and that the dices  number is less than or equal to 6 is 12/12 or 1. It is certain.

hope this helps and hope this correct :)

Answer:

x ≤ 40

Step-by-step explanation:

Given:

[tex]\displaystyle \large{\dfrac{x}{-8} \geq -5}[/tex]

Multiply both sides by -8 to get clear out the denominator:

[tex]\displaystyle \large{\dfrac{x}{-8}\cdot (-8) \geq -5\cdot (-8)}\\\displaystyle \large{x\geq 40}[/tex]

Because the LHS (Left-Handed Side) expression is in negative, make sure not to forget to swap the sign from ≥ to ≤

Hence, the solution is x ≤ 40

Option A

Answer:

n ≥ 29

She needs to do more than 29 pushups on the sixth day.

Step-by-step explanation:

First, we need to use the formula for finding the average. We currently have numbers for the first 5 days.

(22+26+21+25+27+n)/6 = 25

Multiply both sides by 6.

25*6 = 150

150-27-25-21-26-22=x

x=29

Since it is an inequality, Sarah needs to do more than 29 pushups on the sixth day.
