You’re going to need to add a picture to the problem it cannot be solved with just this information
Answer:
See below.
Step-by-step explanation:
For each size, divide the cost by the amount. Make sure the amounts are all in the same units. Then, the lowest cost per unit is the best buy.
3/8 * 6/7
6*3=18
8*7=56
18/56 simplified is 9/28
1. A
**because 21/3 = 7/1
2. 51
Hello from MrBillDoesMath!
Answer: 48.2 degrees
Discussion:
In the diagram, "6" is the x- distance along the side adjacent to theta, and
3 * sqrt(5) is the y-distance along the side opposite angle theta.
By definition of tangent of angle, using "@" for theta, we have
tan (@) = opposite/adjacent = 3 * sqrt(5) / 6 = sqrt(5)/2
So @ = (inverse tangent (sqrt(5)/2) ) = 48.189 degrees (approximately)
Thank you,
MrB
