I think the greatest number of students that can be in each row is 18.
you start by finding the highest common factor of 90 and 72
so it means that the teacher will end up with 5 rows of boys and 4 rows of girls with 18 students in each row.
Answer:
1=110 degrees given
2=70 degrees
3=80 degrees
4=100 degrees
Step-by-step explanation:
1=110
2=180-110=70
3=1/2(100+60)=80 by the angle formed by two chords theorem
4=1/2(80+120)=100 by the angle formed by two chords theorem
Answer:
86.36%
Step-by-step explanation:
Answer:
110
Step-by-step explanation:
Subtract the greater value (115) by the smaller value (105) and this gives you the answer 10. So the distance between the two values is 10. Divide this by 2 to find the midpoint, and you get 5. You can either add 5 to the smaller value, or subtract 5 from the bigger value, either way you would get the answer of 110.
Answer:
x = 6/7 of a puzzle
Step-by-step explanation:
Number of puzzle : time taken
= 3/4 : 7/8
How much a puzzle can she complete in an hour?
Let
x = number of puzzle to complete
Number of puzzle : time taken
= x : 1
Equate both ratios to solve for x
3/4 : 7/8 = x : 1
3/4 ÷ 7/8 = x / 1
3/4 × 8/7 = x / 1
24/28 = x / 1
Cross product
24 * 1 = 28 * x
24 = 28x
x = 24/28
= 6/7
x = 6/7 of a puzzle
