<span><u>Answer </u>
18 feet and 4.5 inches

<u>Explanation </u>
You are going to use the concept of similar triangle.
∆CED≡∆CBA
This is because they share the angle at C and also they both have an angle of 90o.
Let EC = X, then BE = 2.5X. So, BE = (X + 2.5X) = 3.5X
The scale factor EC/BC=x/3.5x=2/7
EC/BC=ED/BA=2/7
BA=7/2×63 in
The height of the tree = 220.5 inches. This is equal 18 feet and 4.5 inches.

goldfiish [28.3K]

Answer:

No solution

Step-by-step explanation:

x - 4y = 1 --> (1)

5x - 20y = 4 --> (2)

y = (¼)x - ¼ --> (1)

y = (¼)x - ⅕ --> (2)

Since these are 2 parallel lines with different y-intercepts, they will never meet

HELP!! WITH THESES MATH QUESTION! WILL MARK BRAINLIEST 70 POINTS!!! PLEASE HELP
Cloud [144]

1. Let hardcover books = X

Paperback books would be 4x -3 ( 3 less than 4 times)

Now you have:

X + 4x-3 = 447

Simplify:

5x - 3 = 447

Add 3 to each side:

5x = 450

Divide both sides by 5:

x = 450/5

x = 90

He has 90 hardcover books.

2. 300 miles / 25 miles per gallon = 12 gallons of gas.

12 gallons x $$ per gallon = $48 dollars

3. Subtract base pay from total:

1916 - 800 = 1,116 worth of commissions.

Divide commissions by percentage:

1116 / 0.09 = $12,400 total sales.

4.

Find the median of the heights: 65-50 = 15. 15/2 = 7.5

Median = 50+7.5 = 57.5

The equation would be |h-57.5| < 7.5
