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

The hyponteuse is 7.7 because it is the longest side of a 90 degree angle.
the formula for this would a^2 + b^2 = c^2
3.3^2 + b ^2 = 7.7^2
10.89 + b^2 = 59.29
- 10.89 - 10.89 subtract from both sides
b^2 = 48.4
[tex]\sqrt{b} = \sqrt{48.4} \\[/tex]

In ΔPQR, p = 8.5 cm, q = 1.7 cm and r=7.7 cm. Find the measure of ∠R to the nearest degree

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°

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. 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= 28.26cm²
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.

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)

then solve and you get x^2 = 64 which means x=8
then since CE and ED are the same and congruent lines ED will also be 8 so you add the 8 up and get 16.
