Answer:
its 42
Step-by-step explanation:
315-18+81=378
Correct mean =378/9=42
Let same number of hours = x,
since the salary earned is also the same, then
Salary of supervisor A = $25x
Salary of supervisor B = $20(30)+$30(x-30)
Equating
25x=600+30(x-30)
30x-25x=900-600
5x=300
x=60 hours
Check:
Salary of supervisor A = 25*60=1500
Salary of supervisor B = 20*30+30*(60-30)=600+900=1500, ok.
Answer:
7.7
Step-by-step explanation: We are trying to find side c or side AB
Using the law of sines formula,
a/sin a= b/sin b c/sin c we can solve for missing side.
We are given side BC or side a which is 11
We also are given angle A is 82 degrees
Angle C is 44 degrees also.
So let set up a proportion.
11/sin 82= x/sin 44
11/sin 82× sin 44=x
x= 7.7
Answer:
Triangle L'M'N' is an enlargement of triangle LMN
Answer:
3/12 = divide 3 to get the lowest number possible (In this case 1, so 3 divided by 3) and then divide the bigger number by same amount you've divided the smaller number (12 divided by 3 is 4, because 4 x 3 = 12). So our answer is 1/4. I'm too lazy to go in depth, but basically, 3 (4 times) is 12, so 3 takes up 1/4th of 12.
