Find the Perimeter of the figure below, composed of an isosceles trapezoid and one semicircle. Rounded to the nearest tenths place

Answer:

27.3

Step-by-step explanation:

Here, we can add the outside sides of the trapezoid, which are already given:

6 + 6 + 9 = 21

Then for the circle, we can find half of the circumference with πr. The diameter of the circle is 4 (given), so the radius (half the diameter) is 2.

Thus,

π(2) ≈ 6.28

By adding all of these parts, you get

21 + 6.28 = 27.28

Which, rounded to the tenths is 27.3

Cubed shaped boxes like the figure shown are used for gifts. Find the surface area to figure out how much wrapping paper is needed to wrap one gift. One box needs ____________ inch squared of wrapping paper. (Round to the nearest square inch.)

(Length is 9.6 all the same for height and width as well)

Simplify the algebraic expression:

2(y + 5) + 3y - 4

Evaluate the expression when x = 2, y = 5, and z = 4.

z2 ÷ 4

Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.

His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.

In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.

Assuming there are no outliers or skew, do the results support Garret's theory?

Select from the drop-down menus to correctly complete the statements.

Since the samples were large and randomly chosen, we can use the samples to understand the populations.

Because the sample mean for students with a grade point average of 3.0–4.0 is

the sample mean for students with a grade point average of 2.0–3.0, the results

Find the surface area of the pyramid. The side lengths of the base are equal.

The graph below shows the winter precipitation in Arizona from 1995 to 2002. It also shows the survival rates of Arizona pronghorn fawns for the same period.

Which two years had the most precipitation?

• Which two years had the best survival rates for fawns?

• Using your knowledge of biotic and abiotic factors and information from the graph, give two reasons why precipitation and fawn population are linked.

• Predict what would happen to the fawn population if the precipitation rate continues to go downward in 2003.
