Answer: 500
Step-by-step explanation: use the equation y=mx+b.
B = cost of the plan per month
X = number of minutes
M = price per minute
The first plan is a flat rate of $25 a month. Whereas the second is $10 plus $0.05 a minute.
Plug in the answers until you get a price that is equal to $25.
Y = 0.05(300) + 10
Y = 25
therefore after 300 minutes the other plan is cheaper
Answer:
A. 9π/2km
Step-by-step explanation:
the length of the arc is
s= angle in radians* radius
the angle in radians
135 = 3π/4
therefore length of arc
s= (3π/4)*6 = 9π/2km
97-25=72 then you would divide 72 by 8 leaving 72/8=9 each chair weighs 9lbs.
Answer:
Eight members of Hoi's family were each charged $4 to go to a movie.
Step-by-step explanation:
The total change from the beginning of the day to the end of the day is 4 29/ 122
<h3>What is rate of change?</h3>
A rate of change is simply a rate that describes how one quantity changes in relation to another quantity.
If a is the independent variable and b is the dependent variable, then:
Rate of change = change in b/change in a
We have that;
- Beginning of the day = 30 1/ 2 = 61/ 2 points
- End of the day = 129 1/4 = 517/ 4 points
Total rate of change = 517/ 4 ÷ 61/ 2
= 517/ 4 × 2/ 61
= 517/ 2 × 1/ 61
= 517/ 122
= 4 29/ 122
Thus, the total change from the beginning of the day to the end of the day is 4 29/ 122
