2 x 5
2+2+2+2+2= 10
2 x 5= 10
A right angle is 90 degrees, so five-thirds of a right angle is 90*5/3=450/3=150 degrees.
Well, mode is the number that occurs most, so the answer would be 7, since that is the most appearing number.
Answer:
680 girls and 850 boys
Step-by-step explanation:
the ratio of girls is 4/9
then we can find the number of girls (G) in the group of 1530 students using proportions:
4 / 9 = G / 1530
solving for G by multiplying both sides of the proportion by 1530, we get:
G = 4 * 1530 / 9 = 680
So there were:
680 girls and 1530 - 680 = 850 boys
