Answer 1
Answer:

a. 32

b. 48

Step-by-step explanation:

Forty percent of the 80 birds were robins.

a. How many of the birds were robins?

b. How many of the birds were not robins?
___________________
Forty percent of the 80 birds that were robins = 40%/100%

To find how many of the birds were robins, use part/whole = part/whole

40%/100% = ?/80

This will tell us how many exact robins were there

To solve, multiply 80 by 40 and then divide all by 100

80 x 40 ÷ 100 = 32

so 32 of the birds were robins

now for b since 32 of the birds were robins out of 80 birds, subtract 32 from 80.

80 - 32 = 48

what is the slope?

Answers

Answer:

2/3

Step-by-step explanation:

Find a two coordinates on the line such as (20,40) and (50,60)

plug it into the slope formula m= y2 - y1 / x2- x1

it doesn't matter what way you plug them in

m = slope

m = 60-40 / 50 - 20 = 20/30 = 2/3

The slope is 2/3 I simplified 20/30 by dividing by 10

Answer:

As follows,

Step-by-step explanation:

The relation between  angle DCF and CFG is co-interior angles, or same side interior angles.

Angle(DCG+CFG)=180

Measure of DCF=180-3x=147 [Because Angle DCF+ACD=180, Angles in a straight line]

Measure of CFG=180-6x-81=33 [Because AngleCFG+HFG=180, Angles in a straight line]

Answers

Answer:

Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)

Step-by-step explanation:

All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!
