Answer:
The length of AC is;
C. 50
Step-by-step explanation:
By the midpoint of a triangle theorem, we have that a segment that spans across and intersects with the midpoints of two sides of a triangle is equal to half the length of the third side and parallel to the length of the third side
The given parameters are;
The midpoints of ΔACE are B, D, and F
The length of EC = 44
The length of DF = 25
Therefore, we have;
Given that DF is a midsegment of triangle ΔACE, then DF ║ AC and
the length of DF = (1/2) × AC the length of AC
∴ The length of AC = 2 × The length of DF
The length of DF = 25
∴ The length of AC = 2 × 25 = 50
The length of AC = 50
7/10 is equivalent to 3.5/5 is one
Answer:
210cm
Step-by-step explanation:
B=l•w
B=5•6
B=30
V=B•h
V=30•7
V=210
Answer:
12 years younger.
Step-by-step explanation:
Let Jan's age be J and Karyn's age be K.
![J= \frac{2}{3} K](https://tex.z-dn.net/?f=J%3D%20%5Cfrac%7B2%7D%7B3%7D%20%20K)
Jan's age 8 years ago is 2/5 of Karyn's age 4 yeaRs from now.
![J-8 = \frac{2}{5} (K+4)](https://tex.z-dn.net/?f=J-8%20%3D%20%5Cfrac%7B2%7D%7B5%7D%20%28K%2B4%29)
=> ![(\frac{2}{3} - \frac{2}{5} ) K = \frac{8}{5} + 8](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B3%7D%20-%20%5Cfrac%7B2%7D%7B5%7D%20%29%20K%20%3D%20%5Cfrac%7B8%7D%7B5%7D%20%2B%208)
=> 4K = 48 X 3
=> K= 36.
=> J= 24.
So Jan is 12 years younger.
