Answer:
27/35.
I can break it down for you to understand if u want.
Step-by-step explanation:
If we know that Pedro bought 1
![\frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20)
pounds of red sand, and 5
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
pounds of brown sand, and they both cost $4.60, then we just have to add the individual amounts of sand, since they cost the same.
![1 \frac{1}{4} + 5 \frac{1}{2} = 6 \frac{3}{4}](https://tex.z-dn.net/?f=1%20%20%5Cfrac%7B1%7D%7B4%7D%20%2B%205%20%20%5Cfrac%7B1%7D%7B2%7D%20%3D%206%20%20%5Cfrac%7B3%7D%7B4%7D%20)
So Pedro bought
![6 \frac{3}{4}](https://tex.z-dn.net/?f=6%20%5Cfrac%7B3%7D%7B4%7D%20)
lbs of sand overall. Now, we just need to multiply the cost per pound by the total amount of sand he bought.
![6 \frac{3}{4} * 4.6 = 31.05](https://tex.z-dn.net/?f=6%20%5Cfrac%7B3%7D%7B4%7D%20%2A%204.6%20%3D%2031.05)
Pedro spent $31.05 on sand, which is answer choice B.
Hope that helped =)
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. That is, in ΔABC, if c2=a2+b2 then ∠C is a right triangle, ΔPQR being the right angle.
It’s c. Where the two planes intersect
One of the ways to find the answer is to find how much 1 percent of 150 is. To do that we just have to divide 150 by 100:
150 / 100 = 1.5
Now we can divide 9 by 1.5 to know how much percent of 150 it is:
9 / 1.5 = 6
Let's check it:
150 * 6% = 150 * 6/100 = 15 * 6/10 = 3 * 6/2 = 18/2 = 9
It's correct then :)
