The answere would be C - 77.27 because you would need to use sin

Answer:
The total number of boys = 105
Step-by-step explanation:
The ratio of boys to girls = 3: 4
⇒ For every 3 boys, there are 4 girls.
Now, total number of students = 245
Let the common ratio of boys to girls is k.
So, 3k + 4k = 245
or , 7k = 245
⇒ k = 245/7 = 35
⇒ k = 35
Hence, the number of boys = 3k = 3 x 35 = 105
and number of girls = 4k = 4 x 35 = 140
A. 400*45.2=400*45+400*0.2=18000+80=18080
B. 14.9*100=15*100-0.1*100=1500-1=1490
C. 76.2*200=76*200+0.2*200=15200+4=15204
You’re correct, it’s 16. Constant proportionality mean how much Y moves. So it’s 16!
In order to know how much of the 3/8 is in the 1/4, you calculate the quotient between 1/4 and 3/8, just as follow:
1/4 ÷ 3/8
you can convert the previous quotient into a multiplication by inverting the second fraction:
1/4 ÷ 3/8 = (1/4) x (8/3) = 8/12 = 2/3
Hence, 2/3 is what 3/8 is in 1/4
