Answer:
This is not a right triangle because 7^2 + 17^2 does not equal 20^2
Step-by-step explanation:
Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
Answer:
A = (100 - y)y
Maximum area = 2500 sq. feet.
Step-by-step explanation:
Let the length of the combined rectangular area is y feet and the shared width is x feet.
So, perimeter of the two rectangle together is (3x + 2y) = 200 {Given}
⇒ 2y = 200 - 3x
⇒
...... (1).
a) Now, area of the total plot in sq. feet is
........ (2)
So, this is the expression for area A in terms of length of shared side x.
b) For area to be maximum the condition is 
Now, differentiating equation (2) on both sides with respect to x we get

⇒ x = 33.33 feet.
So, from equation (1) we get 
⇒ x = 50 feet.
So, the value of maximum area = 50 × 33.33 = 1666.5 sq. feet. (Answer)
The answer is a. n+19=65 n=46 $46. To find out how much more she needs to save, you would add that amount with 19 to get a total of 65. So your equation would be n+19=65. Then once you have your equation, solve it. Subtract 19 from both sides to get n by itself.
n+19=65
-19 -19
n=46
So your answer for how much more she needs to save is $46.
