Answer:
The answer is 40
Step-by-step explanation:
28/x=7/10
firs you need to setup this equation and solve it to get 40
there are 12 girls in the band and 28 boys in the band and I know this because 12+28=40 just like 3/10 + 7/10= 10/10
12 divided by 4 is 3
28 divided by 4 is 7
Answer:
The volume of the pyramid is 33.33 cubic inches
Step-by-step explanation:
we know that
The volume of the rectangular bases pyramid is given by the formula
where
B is the area of the rectangular base of pyramid
h is the height of pyramid
we have
substitute
Basically what is happening is:
You start out with 15. That 1st week you have 22% more than 15, or in other words 15*1.22. The following week you have 22% more than 22% more of 15, which is 15*1.22*1.22.
Now we can write a function that models this situation:
f(n): number of views
n: number of weeks since you started
f(n) = 15(1.22^n)
We want to find out how many views there are after four weeks, so plug 4 in for n.
f(4) = 15(1.22^4)
f(4) = 33.23
This means after 4 weeks you can expect the video to have 33 views.
