Answer:
Triangles PRQ and MRN are not similar.
Step-by-step explanation:
The two triangles are PRQ and MRN.
It is given that both the triangles have ∠R = 90° as the common angle.
Now, we check whether the ratios of the sides are equal or not.
i.e. To check if
Since, we have the lengths,
PM = 8, MR = 10. Thus, PR = 8 + 10 = 18
QN = 14, NR = 7. Thus, QR = 14 + 7 = 21
So, we get,
implies
implies 1.8 = 3, which is not true.
So, the ratio of the sides are not equal.
Hence, we get that the triangle PRQ and MRN are not similar.
Answer:
y = 13/3
Step-by-step explanation:
substitute y=2x+5 in x+y = 4
x+2x+5 = 4
3x+5=4
3x= -1
x= -1/3
substitute x= 1-/3 in x+y = 4
-1/3 +y = 4
y = 13/3
Answer:

Answer:
B. 10 cm³
Step-by-step explanation:
The volume of a prism is found by multiplying its length, width, and height together. So: <em>5/4 * 4 * 2</em>.
5/4 * 4 * 2 = 40/4 = 10 cm³.
What you want to do is do:
0.5 + 0.5 + 0.5 to find how much 3 magazines are.
So, three magazines cost $1.50
