Answer:

Start: Brown feather % is 97% Grey feather % is 3%

End: Brown feather % is 19% Grey feather % is 81%

Step-by-step explanation:

Start:

There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7

divide each number by 7(679/7 and 21/7)

and you get 97 and 3 which will be your percentages

End:

There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4

divide each number by 7.7(140/7.4 and 600/7.4)

and you get about 19(rounded) and about 81(rounded) which will be your percentages

Hope this helps!!!

A book club charges a membership fee of $20 and then $12 for each book purchased. Write a function to represent the change, y, o

riadik2000 [5.3K]

It is y = 12x + 20.
You start with 20 as the y-intercept because that is the starting amount that you paid. The constant rate of change is 12 dollars per book. So, 12 time however many books written as 12x. Hope that helps! :)

If EF bisects angle CEB, angle CEF=7x + 21 and angle FEB = 10x - 3, find the measure of DEB.

morpeh [17]

Answer: DEb = 26°

Step-by-step explanation:

Given information

CEF = 7x + 21

FEB = 10x - 3

Given expression deducted from the definition of the bisector

FEB = CEF

Substitute values into the expression

10x - 3 = 7x + 21

Subtract 7x on both sides

10x - 3 - 7x = 7x + 21 - 7x

3x - 3 = 21

Add 3 on both sides

3x - 3 + 3 = 21 + 3

3x = 24

Divide 3 on both sides

3x / 3 = 24 / 3

x = 8

Find the sum of the angle of CEF and FEB

7x + 21 + 10x - 3

=7 (8) + 21 + 10 (8) - 3

=56 + 21 + 80 - 3

=77 + 80 - 3

=157 - 3

=154

Subtract 154 from the straight angle

DEB = 180 - 154

$\boxed{DEB = 26}$

Hope this helps!! :)
