Somebody help me with this math, please! 15 Points for TWO thoughtful, well-explained, correct answers.
Sauron [17]
In both parts, we have to apply "Proportionality Theorem" which tells, ratio of corresponding part should be equal.

1) CD/BD = FE/GE
8/24 = 6/GE

GE = 6*24 / 8
GE = 18 

2) BC/BD = EF/EG
14/BD = 5/15
BD = 42

Now, CD = BD - BC
CD = 42 - 14 = 24

Hope this helps!

Solve for the given length:
Lesechka [4]
Let x= width
Then x+3= length
So 2x+2x+6=26
4x+20
x=5
Width is x=5m and length is x+3=8m
Area is (lenght)(width) so (5)(8)= 40m squared

Taminka received a raise in her hourly pay, from $13.50 to $14.99. Find the percent change. Round to the nearest percent.
polet [3.4K]

Answer:

\% = 11\%

Step-by-step explanation:

Given

Initial = \$13.50

Final = \$14.99

Required

Determine the percentage change

This is calculated as:

\% = |\frac{Initial - Final}{Initial} * 100\%

\% = |\frac{13.50 - 14.99}{13.50}| * 100\%

\% = |\frac{-1.49}{13.50}| * 100\%

\% = \frac{1.49}{13.50} * 100\%

\% = \frac{1.49* 100\%}{13.50}

\% = \frac{149\%}{13.50}

\% = 11.037037037\%

\% = 11\%
