Step-by-step explanation:
Answer: There are 60 girls and 40 boys at the bar-b-que
============================================================
Explanation:
b = number of boys
g = number of girls
"The ratio of boys to girls is 4:6" so
b = 4*x
g = 6*x
where x is some positive whole number
Add up the counts of boys and girls. This count should equal 100
b+g = 100
Plug in b = 4x and g = 6x. Then solve for x
b+g = 100
4x+6x = 100
10x = 100
10x/10 = 100/10 ... divide both sides by 10
x = 10
If x = 10, then
b = 4*x = 4*10 = 40 ---> there are 40 boys
g = 6*x = 6*10 = 60 ---> there are 60 girls
we can see that the ratio
40 boys: 60 girls
reduces to
4 boys: 6 girls
In other words, for every 4 boys, there are 6 girls. The ratio 4:6 can be fully reduced to 2:3 which means for every 2 boys, there are 3 girls.
Side note: if the ratio of vegetarian girls to omnivorous girls is 1:1, then there are 30 of each
we can solve y+y = 60 to find that y = 30, or we can simply divide 60 in half to find this count. Saying "a ratio of 1:1" means that there are the same number of vegetarians as omnivorous girls.
Answer:
26
Step-by-step explanation:
Multiple by 65 by 40% or 0.4 and you get 26 .
A.)7/4; –10
7/4 is the slope. It just has an x behind it. -10 Is the intercept. It is after the x.
