Answer:

C. $63.00

Step-by-step explanation:

(6*50*0.01)+(5*40*0.05)+(4*50*0.10)+(3*40*0.25)=\\(300*0.01)+(200*0.05)+(200*0.10)+(120*0.25)=\\3+10+20+30=\\13+20+30=\\33+30=\\63

Answer:

pennies = 1cent

50 cents per roll

that's three dollars

nickels = 5cents

200 cents per roll or 2dollars

that's ten dollars

dimes = 10cents

500 cent or five dollars

20 dollars

quarter = 25cents

four quarters equal a dollar  

4/40= $10x3=$30

30+20+10+3=$63

<1 and <2 form a linear pair. If m<1= 4m<2, find the measure of each of the two angles.
ozzi

Answer:

  • The angle ∠1 = x = 36°
  • The angle ∠2 = 4x = 4(36°) = 144°

Step-by-step explanation:

We know that when two lines meet or intersect, we get a linear pair of angles.

Linear pairs are basically two adjacent angles that form a line.

The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.

We are given that <1 and <2 forms a linear pair, and

m∠1 = 4m∠2

It means the angle ∠1 is 4 times the measure of angle ∠2.

Let the angle ∠1 be = x

As the angle 1 is 4 times the measure of angle ∠2, so

The angle 2 will be = 4x

As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so

x + 4x = 180

5x = 180

divide both sides by 5

5x/5 = 180/5

x = 36°

Therefore,

  • The angle ∠1 = x = 36°
  • The angle ∠2 = 4x = 4(36°) = 144°

Dimas [21]
ANSWER- x-axis

If the point is graphed, the point is not in any quadrants, there for your only choices are x and y axis. When you look at the point, you notice the point is on the horizontal line and that lead to the conclusion, its on the x-axis.

The length of a rectangle is 11 in. longer than its width. the perimeter of the rectangle is 86 in.write and solve an equation t
Tcecarenko [31]
I hope this helps you


width w


length w+11



perimeter =2 (width +length )


86=2 (w+w+11)


43=2w+11


32=2w


w=16

length = w+11=16+11=27
