Hugh pays $9.99 a month for an online movie rental service. The service allows him to rent and watch movies for $0.89 each. If Hugh has set a budget of $30 per month for the movie service, which inequality can he use to find
m
, the maximum number of movies he can rent each month?
Answer:
22 movies per month.
Step-by-step explanation:
30=9.99+0.89m
30-9.90=0.89m
20.01/0.89=m
22.48=m

what are the x and y intercepts
m < CDB equals what ?
I’ll give brainliest!
Answer:
∠ CDB = 43°
Step-by-step explanation:
Angles subtended at the circumference by the same arc are congruent.
The arc CB subtends both ∠ CAB and ∠ CDB , thus
∠ CDB = ∠ CAB = 43°

Find m∠MON
I have a hard time with theses
Answer:
m∠MON = 15°
Step-by-step explanation:
The given parameters are;
m∠LON = 77°
m∠LOM = 9·x + 44°
m∠MON = 6·x + 3°
By angle addition postulate, we have;
m∠LON = m∠LOM + m∠MON
Therefore, by substituting the known values, we have;
∴ 77° = 9·x + 44° + 6·x + 3°
77° = 9·x + 44° + 6·x + 3° = 15·x + 47°
77° = 15·x + 47°
77° - 47° = 15·x
15·x = 77° - 47° = 30°
15·x = 30°
x = 30°/15 = 2°
x = 2°
Given that m∠MON = 6·x + 3° and x = 2°, we have;
m∠MON = 6 × 2° + 3° = 12° + 3° = 15°
m∠MON = 15°.

What is the equation of the line that passes through the point (4,−2) and has a slope of -2
Answer:
y = -2x + 6
Step-by-step explanation:
Point slope form is y - y1 = m(x-x1)
y - (-2) = -2(x-4)
y + 2 = -2x + 8
y = -2x + 6
The expression -7y is a
A: Constant
B: Term
C: Variable

A roller coaster can hold 32 people at a time. There are 275 people waiting to ride the roller coaster. How many trips will the roller coaster have to make for all the people to ride?
Answer:
9
Step-by-step explanation:
275 divided by 32 in equal to 8.59, so you just have to round up but that last trip just wont be full
Answer:
9 roller coaster rides. hope this helps!
Step-by-step explanation:
A roller coaster can hold 32 people at a time.
there are 275 people waiting in line.
How many trips will it take for there to be 0 people waiting in line?
We know the roller coaster can hold 32 people at a time, and 275 people are waiting in line.
275/32=8 rides and 19 people left.
If you don't know how to do that: 275 people at first. 275-32 because the roller coaster can only hold 32. Repeat that process untill you find your answer.
So we have 8 rides, and 19 people left? It doesn't matter, It will not take, half the time left, or more time to get it done. So anything below or equal to 32 people will take the same amount of time. So our final answer is 9 rides. Not 8.59375.

Answer:
The answer is 50 degrees
Step-by-step explanation:
The small box at the corner of the triangle indicates that the triangle is exactly 90 degrees, or a right angle. In order to solve the expression, you would need to do 40 + x = 90, which would be x = 50
Answer:
It should be 40 degrees, If you have a protractor, you could measure it.
Step-by-step explanation:
I think it's 40 degrees because if you fold it in half, it would probably match.
