**Answer 1**

Answer:

3.75 times

Step-by-step explanation:

From the histogram plot of the data :

The number of people who sleep 8 - 8.9 hour per night is about 375

The number of people who sleep 6 - 6.9 hour per night is about 100

Therefore, to compare how many times the number of people who sleep 6 - 6.9 hrs and 8 - 8.9 hrs :

8 - 8.9hrs = 6 - 6.9 hrs * x

375 = 100x

x = 375 / 100

x = 3.75

Hence, the number of people who sleep 8 - 8. 9 is 3.75 times the number of people who sleep 6 - 6.9

What is trigonometry?

The branch of **mathematics **that sets up a relationship between the sides and the angles of the right-angle triangle is termed **trigonometry**. The trigonometric functions, also known as a circular, angle, or goniometric **functions **in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that in ΔPQR, p = 8.5 cm, q = 1.7 cm and r=7.7 cm. The value of angle ∠r will be calculated as,

r² = p² + q² -2pqcos(r)

(7.7)² = (8.5)² + (1.7)² - 2 x 8.5 x 1.7cos(r)

59.29 -75.14 = -28.9cos(r)

cos(r) = 15.85 / 28.9

cos(r) = 0.55

r = cos⁻¹(0.55)

r = 56.63°

Graphs of the functions f and g are shown in the xy-plane. For which of the following values of x does f(x) + g(x) = 0?

### Answers

Answer:

-2

Step-by-step explanation:

The functions of f(x) and g(x) are given

For f(x)+g(x)=0 , functions f and g should be in opposite sign

We can observe that at x=−2 , f(x)=2 and g(x)=−2

Therefore f(−2)+g(−2)=0

So the correct option is D (-2)

The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.

### Answers

**Answer:**

423

**Step-by-step explanation:**

Firstly we need to find the circumference of the circle.

Circumference = 2 × Radius with Pi

=2×8×3.14= 50.24

Now we must find the area of 1 label.

**Area**** ****of**** ****1**** ****label****=**** ****3.14**** ****×**** ****9****=**** ****28.26cm****²**

Multiplying by the number of labels =

28.26 × 15

= 423.9 cm²

So, we'll just keep the answer 423 because we were asked how many square inches of paper will be needed.
