Answer:

The radius is <u>63.69</u>.

Step-by-step explanation:

Given:

The circumference of a circular track is 400.

Now, to find the radius:

So, to get the radius(r) we put the formula of circumference:

$Circumference=2\pi r$

⇒ $400=2\times 3.14\times r$

⇒ $400=6.28\times r$

<em>Dividing both sides by 6.28 we get:</em>

⇒ $63.69=r$

⇒ $r=63.69$

Therefore, the radius is 63.69.

At a certain electronics company, the daily output Q is related to the number of people A on the assembly line by Q=600+√(A+41).

Ber [7]

Answer:

$A=400\ people$

Step-by-step explanation:

we have

$Q=600+\sqrt{A+41}$

where

Q -----> is the daily output

A -----> is the number of people

For Q=621

Find the value of A

substitute and solve for A

$621=600+\sqrt{A+41}$

Subtract 600 both sides

$621-600=\sqrt{A+41}$

$21=\sqrt{A+41}$

squared both sides

$21^{2} ={A+41}$

$441={A+41}$

Subtract 41 both sides

$441-41=A$

Rewrite

$A=400\ people$

A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 1 or a 9 is 2/9 .

USPshnik [31]

The answer would be 7/9. If the spinner has 9 sections and you want to know the probability of NOT landing on a 1 or a 9, you would subtract 2 from 9 since there are 2 numbers and 9 total.

Can u guys PLEASE ANSWER this question ASAP.

Answer:

x = -14

Step-by-step explanation:

The expression to write in this problem is:

"the sum of x and 12 equals the sum of half of x and 5"

We have:

- The sum of x and 12 is: $x+12$

- The sum of half of x and 5 is: $\frac{1}{2}x+5$

So, the equation to write in this problem is

$x+12=\frac{1}{2}x+5$

We solve it as follows:

1) First, we subtract $\frac{1}{2}x$ from both sides, and we get

$x-\frac{1}{2}x+12=\frac{1}{2}x-\frac{1}{2}x+5\\\frac{1}{2}x+12=5$

2) Then, we subtract 12 from both sides:

$\frac{1}{2}x+12-12=5-12\\\frac{1}{2}x=-7$

3) Now we multiply both sides by 2:

$\frac{1}{2}x\cdot 2=-7\cdot 2\\x=-14$

So, this is the solution.
