area of painting = 13 * 17 = 221 square inches
221 * 0.30 = 66.30
the price would be $66.30
3m+21=6m
=>21=6m-3m
=>21=3m
=>7=m
Therefore option A is the answer
You know how Soh Cah Toa applies to right triangles; you can assign the adjacent side = 4 and hypotenuse = 7
CosФ = (adjacent) / (hypotenuse)
Then with the Pythagorean theorem
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
b = √(33)
So "b" is the opposite side.
SinФ = (opposite) / (hypotenuse) = √(33)/7
TanФ = (opposite) / (adjacent) = √(33)/4
Yes, you are correct. The answer to your problem is indeed 4.
Answer:
Your brother gets $16 and you get $8.
Step-by-step explanation:
first of all what is 16+8=24
first step..i started from 2 and did twice of that wich is 4 but that only got $6
second step.... just keep doing your multiples....
third step....as soon as i got to the number 8 i did twice of that and i got 16 then i added those and i got $24
and that is your answer.
