Answer:

$13.75 per hour is Nikki's pay rate.

Step-by-step explanation:

We can find the hourly pay rate for Nikki by dividing the total pay by the total number of hours worked:

343.75 dollars / 25 hours = ? / ? dollars/hour (or dollars per hour)

$13.75 per hour is Nikki's pay rate.

Answer:

13.75

Step-by-step explanation:

How can you know how much Niki can get per hour? Well, the ratio is 343.75 :25, so 25 hours divided by 25 is 1, meaning 1 hour. If you are dividing 25 by 25 hours, do the same for 343.75. This will become 13.75.

The bottoms of two vertical poles are 12 feet apart and are on a region of flat ground. One pole is 6 feet tall and the other is
snow_tiger [21]

Answer:

The length of the wire is 15 ft.

Step-by-step explanation:

The solution of this exercise comes from an application of the Pythagorean theorem. The explanation here is complemented with the figure attached.

In the figure the segments AB and CD represents the vertical poles, where the length of AB is 6 ft and the length of CD is 15 ft. We want to find the length of the segment BD, that represents the stretched wire. The length of the segment AC is 12 ft, which is the distance between the poles.

If we draw an imaginary line from A perpendicular to DC, we obtain a rectangle ABEC, and a right triangle BED. Then, the length of BE is 12 ft. Moreover, the length of CE is 6 ft, because is equal to the length of AB. Hence, the length of DE is 9 ft, because DE = DC-EC.

As we want to find the length of the hypotenuse BD of the right triangle BED, and we already have the lengths of the other two sides, we only need to apply the Pythagorean theorem. This is

BD^2 = BE^2 + ED^2 = 12^2+9^2= 144+81=225.

Then, taking square roots in both sides: BD=15 ft.

The attendance at the art museum at the New Year's opening was 250 people. The attendance has been increasing at a rate of 3% ea
erastovalidia [21]

Given:

Initially the number of people at art museum = 250

Rate of increase = 3% per month

To find:

The number of people at art museum in the end of a year.

Solution:

The general exponential growth model is:

y=a\left(1+\dfrac{r}{100}\right)^t

Where, a is the initial value, r is the rate of increase in % and t is the time period.

We know that, 1 year = 12 months.

Putting a=250, r=3 and t=12, we get

y=250\left(1+\dfrac{3}{100}\right)^{12}

y=250\left(1+0.03\right)^{12}

y=250\left(1.03\right)^{12}

y=250(1.42576)

y=356.44

y\approx 356

The number of people at the end of a year is 356. Therefore, the correct option is D.
