Answer:
90
Step-by-step explanation:
18:
18*1=18
18*2=36
18*3=54
18*4=72
18*5=90
18*6=108
45:
45*1=45
45*2=90
45*3=135
Therefore, 90 is the correct answer
Answer:
16 batches are to be made for the party.
Explanation:
Given:
Number of batches for every 9 people= 2
Total number of people attending the party=72
To Find:
The Number of batches required=?
Solution:
Let the number of batches for 72 people be n
So, by cross multiplication method,
2 x 72 = n x 9
9n = 72 x 2
n = 8 x 2
n = 16
Answer:
x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.
Step-by-step explanation:
Let Lin works x hours per week.
Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.
And she has to work at least 5 hours a week to $175 per week.
So, the inequality that can be written from the above condition is x ≥ 5 .......(1)
And the equation that can be written that
8.25x + 10 = 175 ....... (2)
Now, fro equation (2) we can write x = 20 hours which satisfies equation (1).
The central angle corresponding to AOB is half of the 8pi/9 radians mentioned, meaning that the central angle of AOB is 4pi/9.
Converting that to degrees:
4pi/9 180 degrees
-------- * -------------------- = 80 degrees.
1 pi
