Answer:

25 years

Step-by-step explanation:

To find the mean you need to find the sum of all numbers and divide by the number of terms there are.

In this case you would need to multiply the mean ages by the number of people used to find the mean:

35 * 3 = 105

23 * 12 = 276

Then add the total ages together:

105 + 276 = 381

Then divide by the number of total people in the office:

12 + 3 = 15

381/15 = 25.4

rounded to 25

Nata [24]

Your question: The graph above shows a polynomial function with ___

<h3>Answer: B,  a polynomial function with an odd degree and a positive leading coefficient</h3>

Step-by-step explanation: If the degree of a polynomial f(x) is even and the leading coefficient is positive, then f(x) → ∞ as x → ±∞. ... If f(x) is an odd degree polynomial with positive leading coefficient, then f(x) →-∞ as x →-∞ and f(x) →∞ as x → ∞.

I hope this helps, mate!

Express 20% as a fraction in its lowest form? Thanks
lilavasa [31]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ 20% as as a fraction in lowest terms is \frac{1}{5}

Percents are out of 100% so write 20% out of 100% as a fraction:

\frac{20}{100}

Both the numerator and denominator can be divided by 20 so once divided, you get \frac{1}{5}

two wheels are rolled simultaneously. The radius of the smaller wheel is r feet and the radius of the larger wheel 2r feet. If b
Nuetrik [128]
The circumference of a circle is C=2πR, where R is the radius of the circle and π≈3.14.

So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R

4 rotations mean 4 circumferences that is 4 segments of length 6.28R, 
which makes a linear distance of 4*6.28R=25.12R


i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet

ii: the radius of the smaller wheel is R=2r, thus it covers a distance of  25.12*2r=50.24r (feet)

50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.


Answer: the larger covered twice the distance of the smaller.
