The Proportion for the 15/11=28/x
let x be the shadow that is cast by the tree.
so x=(11*28)/15
x= 20.533

Answer:
<h2>32° and 58°</h2>
-by-step explanation:
Let x be the measure of angle 1
and y be the measure of angle 2
The Two angles are complementary
means
x + y = 90
their difference is 26 degrees
means
x - y = 26
x + y = 90 (1)
x - y = 26 (2)
(1) - (2) ⇒2y = 64 ⇒ y =32°
therefore x = y + 26 = 58°

Answer:
0.625lb bag of bird seeds
Step-by-step explanation:
She starts with a 3.5 lb bag,
Then she uses 3/4 of the bag, so find the remaining amount in the bag, which would be 1/4 of the original weight;
1/4 * 3.5
= 1/4 * 7/2
= 7/8
Then she removes 0.25 lbs of weight, hence take away 0.25 (the amount removed) from 7/8 (the current weight of the bag).
7/8 - 0.25
= 7/8 - 1/4
= 7/8 - 2/8
= 5/8
So she has a 5/8lb bag of bird seeds or a 0.625lb bag.
We have 
.
First let us factor the 2 to obtain,
We can now see clearly that the expression inside the parentheses is a difference of two squares.
We now write the 4 as 2². So that we obtain the expression,
Recall that
Hence our expression becomes,
Therefore, when factored completely,
The answer would be:
C. 144in2
hope that helped
