Answer:
The number of boys last year will be 50 boys
Step-by-step explanation:
330 members with 240 adults
The number of children will be;
330-240 = 90
2/3 of 90 are boys
= 2/3 * 90 = 60 boys
Number of girls is 90-60 = 30
Ratio of adults:boys:girls
= 240:60:30
divide through by 30
= 8:2:1
b) A year ago, there were 200 adults but the ratio still remains same
Let the number of girls be x, the number of boys will be 2x
Thus, total number is 200 + x + 2x = 200 + 3x
Total ratio is 8 + 2 + 1 = 11
mathematically;
8/11 * (200 + 3x) = 200
8(200 + 3x) = 11(200)
1600 + 24x = 2200
24x = 2200-1600
24x = 600
x = 600/24
x = 25
So the number of boys will be 25 * 2 = 50
The answer is 45 okay bro good
Answer:
Step-by-step explanation:
what he said was he right answer
The percent of total calories from fat is 60%
Step-by-step work:
190 calories is the total amount of calories in the chicken nuggets and 114 calories are from fat so you could write that as:
114/190
now remember that a “/“ also means divide, so divide the fraction:
114/190 = 0.6
0.6 is the decimal form of 114/190
then since percentages are out of 100, you multiply it by 100:
0.6 • 100 = 60
and 60% is your final answer!
The formula for exponential functions is:
y = ab^x
