Answer:
15. d) 36
16. b) 20
17. d) 180
18. b) 50
19. c) 360
20. b) 60
Step-by-step explanation:
To find the number of sides a polygon has giving an interior angle, use the equation:
(number of sides - 2)*180/(number of sides) = measure of interior angle
15. (n = number of sides)
((n-2)*180)/n = 170
180n-360 = 170n
10n = 360
n = 36 (d)
16. (n = number of sides)
((n-2)*180)/n = 162
180n-360 = 162n
18n = 360
n = 20 (b)
17. The sum of the interior angles of a triangle is always 180 (d)
18. 180-60-70 = 50 (b)
19. The sum of the interior angles of a quadrilateral is always 360 (c)
20. 360-120-90-90 = 60 (b)

A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day

solve the equation for the value of x. 1/6 (18-x) = 0
Answer:
x=18
Step-by-step explanation:
Given a circle with radius of 18 m, what is the diameter?
Answer:
d=36m
Step-by-step explanation:
d=2r=2·18=36m
Answer:
Your in luck! I'm actually learning this right now!
Step-by-step explanation:
d = 2r so basically your diameter is your radius times 2! So 18 x 2 = 36 so the answer should be 36 hope this helps!

Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth
Mean: _ minutes
Median: __ minutes
Answer:
mean: 65
median: 9
Step-by-step explanation:
You take all the numbers you have and add them up. Make it simple by adding smaller numbers together. Then once you have the total which is 65 you divide it by the total of numbers you have and then round because after dividing you get 8.125 and the safest way to round is to 9.

Kayla buys a video game for $19 plus a 6% tax. Michael buys a volleyball for $18 plus a 6% tax Enter the diference in the
amount Kayla and Michael paid, including tax. Round your answer to the nearest cent.
Answer:
$1.06
Step-by-step explanation:
Kayla: 19 increase 6% =
19 × (1 + 6%) = 19 × (1 + 0.06) = 20.14
Michael: 18 increase 6% =
18 × (1 + 6%) = 18 × (1 + 0.06) = 19.08
Difference: 20.14 - 19.08 = 1.06

A school club sold 300 shirts. 31% were sold to fifth-graders, 52% were sold to sixth graders, and the rest were sold to teachers. How many shirts were sold to each group -- fifth graders, sixth graders, and teachers? Explain or show your reasoning.
Answer:
Fifth graders= 93 shirts
Sixth graders= 156 shirts
Teachers= 51 shirts
Step-by-step explanation:
31% of 300 is 93
52% of 300 is 156
The total number of shirts sold to fifth graders and sixth graders is:
156+93= 249
The number of shirts sold to teachers is:
300-249= 51
