A class contributed $19.00 in quarters and dimes to a local homeless shelter. In
all there were 100 coins. How many were there of each kind.

Answers

Answer: 60 quarters and 40 dimes

Step-by-step explanation:

Step 1: Setup Coin Value and Coin Total Equation:

Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters

Coin Total Equation → d + q = 100

Step 2: Rearrange Coin Total Equation in terms of dimes (d)

d = 100 - q  ← Revised Coin Total Equation

Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:

0.1(100 - q) + 0.25q = $19.00

0.1(100) - 0.1(q) + 0.25q = $19.00

10 - 0.1q + 0.25q = $19.00

10 + (0.25 - 0.1)q = $19.00

10 + 0.15q = $19.00

Step 4: Subtract 10 from each side of the equation to isolate q

10 - 10 + 0.15q = $19.00 - 10

0.15q = 9

Step 5: Divide each side of the equation by 0.15 to isolate q

0.15q/0.15  =    9/0.15

q = 60

Step 6: Using our value for q, Solve for d using our Coin Total Equation:

d + 60 = 100

Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60

d = 40

Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00

A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation LaTeX: 1.5s+3.5c=21 represents the relationship between sheets of stickers, LaTeX: s, packs of cardstocks, LaTeX: c, and the dollar amount a kindergarten teacher spent on these supplies.

Answers

Answer:

Done

Step-by-step explanation:

Teacher bought $21 worth of stickers and cardstock for his class.

Cost of stickers = $1.50 per sheet

Cost of 's' sheets = $1.5s

Cost of cardstock = $3.50 per pack

Cost of 'c' packs = $3.5c

Equation representing the relationship between sheet of stickers and packs of cardstocks will be,

1.5s + 3.5c = 21

3.5c = -1.5s + 21

1).  

  y-intercept of the line → (0, 6)

  x-intercept of the line → (14, 0)

  Therefore, equation of the line represents the line on the graph.

2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.

  Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.

For Exercises 8 and 9, find the lengths of all three sides of the triangle.

Answers

9514 1404 393

Answer:

  8. GH = 49; HJ = 35; JG = 35

  9. KL = 26, LM = 26, MK = 20

Step-by-step explanation:

8. The sides opposite the marked angles are congruent.

  JG = JH

  3x +8 = 35

  3x = 27 . . . . . . . subtract 8

  x = 9 . . . . . . . divide by 3

We already know JG and JH, so we only need to find GH:

  GH = 6x -5 = 6(9) -5 = 54 -5 = 49

Then the side lengths are ...

  GH = 49, HJ = 35, JG = 35

__

9. This, too, is an isosceles triangle.

  LK = LM

  26 = 2y+8

  18 = 2y . . . . . . . subtract 8

  y = 9 . . . . . . . divide by 2

  KM = 3(9) -7 = 27 -7 = 20

Then the side lengths are ...

  KL = 26, LM = 26, MK = 20

Answers

Answer:

Hey girl! I got you.

Step-by-step explanation:

So! The angle x and z are congruent, meaning that they are equal, so you got that part correct. They are indeed 103. Next you need to find y, and in this case you need to do 180 - 103 because the line that holds both angle z and angle y is equal to 180.

180 - 103 = 77, you got that correct also!

You're on the right track, just explain in words how you know what each angle is equal to! Good luck! :)

angle1,2 , and angle3 form a straight line. If m angle3 is six more than twice m angle1 m angle2 is 27 less than m angle3 find m angle2

Answers

Since it's an angle on a straight line, the value of angle 2 is 23.25°

Angle 1 = m

Angle 2 = m - 27

Angle 3 = 2m + 6

It should be noted that the sum of angles in a straight line is equal to 180°, therefore we need to equate all the angles given to 180°. This will be:

m + (m - 27) + (2m + 6) = 180°

m + m - 27 + 2m + 6 = 180°

4m = 180° + 27° - 6°

4m = 201°

m = 201/4

m = 50.25°

Therefore, angle 2 will be:

m - 27 = 50.25 - 27 = 23.25°
