Answer:
C
Step-by-step explanation:
Total of 40 cups and 25 of them are chocolate so the proportion for chocolate would be 25/40
triangle ABC is a right isosceles triangle
***on the paper i accidentally wrote scalene instead of isosceles
1:
A has volume 9*6*5=270 and surface area 2*(9*6+9*5+6*5)=258.
B has volume 9*3*10=270 and surface area 2*(9*10+9*3+3*10)=294.
D is the correct answer.
2: The surface area is 2*(6*8+6*13+8*13)=460.
3: The area of one of the triangular areas is 5*24/2=60, the area of one of the upper rectangles is 13*16=208, and the area of the lower one is 16*24=384.
There are two triangles, two upper rectangles, and one lower rectangle, so we have a total of 60*2+208*2+384=920.
4: The bottom square has area 30*30=900, and each upper triangle has area 30*45/2=675. We have four triangles and one square, so our answer is 675*4+900=3600.
The sum of x and y are 116 degrees. X=54 degrees and y=62 degrees.
Explanation
==================
in point o they have 2 angles that are vertical to each other meaning that they are congruent to each other. One of the angles is 64 degrees so the other angle that is vertical to it would be 64 degrees also. So, if we have the two triangles that have 2 angles we can know the last remaining angles since the triangles would need to add to 180 degrees. In triangle 1, we have 62 degrees and 64 degrees. We add them together to get 126 and we subtract 126 from 180 degrees to get the last angle which is 54 degrees. Moving on to the next triangle. We have 64 degrees and 54 degrees. We add them together and get 118 and we subtract 118 from 180 to get 62 degrees. Now that we found out that x=54 and y-62 we add them together and we get 116.
Hope this helps :)
-5v = 6v + 5 - v
-5v - 6v + v = 5
-11v + v = 5
-10v = 5
v = 5/-10
v = -1/2
