40s+2bs+200=number of books needed
if we want 12 books and 8 stalls
b=12
s=8
solve
40(8)+2(12)(8)+200=
320+192+200=
712
needs 712 books
Answer:
A. I can't quite see the question, but I'm pretty sure it's A
Step-by-step explanation:
Sin(A) = 1/3
Sin^2(A) + Cos^2(A) = 1
(1/3)^2 + cos^2(A) = 1
1/9 + cos^2(A) = 1
cos^2(A) = 1 - 1/9
cos^2(A) = 8/9
cos(A) = √(8/9)
√8 = √(2 * 2 * 2) = 2√2
√9 = 3
cos(A) = 2√2/3
Simple...
you have:

and

To solve for....

Multiply to remove the denominator-->>

n=12*3
n=36
Then-->>>

Do the same thing-->>

n=-12*3
n=-36
Thus, your answer.
Answer:
17%, or $25.50
Step-by-step explanation:
If Ricardo has already saved 83% of the money, then he needs to save 17% more, because 83% + 17% = 100%
So what you need to do to figure out the answer is to find out 17% of $150
You first have to convert 17% into decimal form which is 0.17.
Then, you multiply 0.17 × 150 = 25.5
Ricardo needs $25.50 to buy the skateboard.
Hope this helped.
