Answer:
[1,∞) Third one down.
Step-by-step explanation:
Comment
A couple of notes so you know what we are looking for.
- (a,b) means that neither a nor b are included in the interval.
- [a,b] means that both a and b are included in the interval/
- Range means the y value.
Graph
The graph shows that the interval of the range is from 1 to infinity. Infinity is never part of a domain or a range. The bracket after infinity must be ( or ) depending on where infinity is. Nothing is eliminated by that fact.
The low point is 1, not minus 1. So the first and second choice are both incorrect.
The graph never crosses the x axis. - infinity cannot be even a limit of the interval. That makes the second and the last one incorrect.
Only the third one down is left. [1, ∞) is left. It is correct. 1 is part of the interval. Infinity is not.
Answer:
r = 62
Step-by-step explanation:
Angles add up to 180 so:
r + r + 56 = 180
2r + 56 = 180
2r = 180 - 56
2r = 124
r = 62
It is not possible for 120 kids and 20 adults to go on the trip, but 120 students can go with a maximum of 12 adults so the expense of the trip can fall in the school's budget.
We know that tickets of the zoo cost $15 for adults and $11 for children.
The equation representing the budget for the trip is 15x + 11y = 1500.
where, x is the no. of adults and y is the number of children that are travelling.
If x = 20 and y = 120 then,
15(20)+11(120)=300+1320=1620 which is out of the budget of the school.
If 120 students want to go to school then, no. of adults that can travel can be determined as
15 x + 11 (120 )<= 1500
15x <=1500-1320
15x<=180
x <=12
Therefore, we can conclude that 120 students and 20 adults cannot travel for the trip but 120 students can travel with a maximum of 12 adults among with them as it will cost school the trip in the budget.

4x80=320
Work:
4x8 = 32
(4+4+4+4+4+4+4+4)
Now carry the 0 and you get 320
