Answer: The measure of AC is 32.
Explanation:
It is given that the Points B, D, and F are midpoints of the sides of ΔACE. EC = 38 and DF = 16.
The midpoint theorem states that the if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.
Since F and D are midpoints of AE and EC respectively.
So by midpoint theorem length of AC is twice of DF.
Therefore, the length of AC is 32.
The interest rate is B. 4%
Given:
Principal = 450
Interest = 126
term = 7
rate = ?
Simple Interest is computed by multiplying the Principal, rate, and term.
Interest = P × r × t
126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%
To check:
I = 450 × 0.04 x 7
I = 18 × 7
I = 126
So, you already know that you have to multiply the value of 7 by the variable and the number inside of the parentheses. So, 7 x A = 7A, and 7 times -6 equals -42. So, your answer would most likely be 7a - 42.
Answer:
Step-by-step explanation:
<u>Use Pythagorean to solve this:</u>
- FH² = FG² - GH²
- GH² = EG² - EH²
<u>Substitute values:</u>
- FH² = 85² - (45² - 27²)
- FH² = 5929
- FH = √5929
- FH = 77
