Part B: You have $0.80 in your backpack in dimes and quarters. Let x represent the number of dimes and y represent the number of quarters. If you have 2 quarters in your backpack, how many dimes do you have?
______


Answers

Answer 1
Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3
Therefore you have 3 dimes

Zanara has 7 heart stickers and 24 cupid stickers. She wants to divide into 3 equal groups to give to her friends. How many stickers will each group have?

Answers

Answer: Each group will have  10 stickers.

Step-by-step explanation:

Given: Number of heart stickers = 7

Number of cupid stickers = 24

Total stickers = 7+24 = 31

If she divides them into 3 groups, then each group will have [tex]31 \div3[/tex] stickers

= 10 stickers ( 1 left)    [ when we divide 31 by 3 , we get 10 as quotient and 1 as remiander ]

Hence, each group will get 10 stickers.

Area of triangle = ½bh
Area of rectangle = bh

Total area = Area of triangle + Area of rectangle

Area of rectangle = (12 cm)(9 cm)
Area of rectangle = 108 cm²

Area of triangle = ½(9 cm)(7 cm)
Area of triangle = ½(9 cm)(7 cm)
Area of triangle = 31.5 cm²

Total area = 31.5 cm² + 108 cm²
Total area = 139.5 cm²

The dimensions of an actual swing set are shown. You want to create a scale model of the swing set for a dollhouse using similar triangles. Sketch a drawing of your swing set and label each side length. Then write a similarity statement for each pair of similar triangles and state the scale factor you used to create the scale model.

Answers

The dimensions of the scaled drawing are half the lengths of the dimensions of the original drawing

What are scaled drawings?

Scaled drawings are diagrams that shows the image of an object drawn in a reduced or enlarged proportional size.

How to determine a scale ratio

If the diagram is to be enlarged, then the scale ratio will be greater than 1.

However, smaller diagrams will have a scale ratio less than 1

In this case, we make use of a scale ratio of 0.5 or 1/2

This means that, the scaled drawing will have its lengths to be half of the original drawing

See attachment for the original drawing and the sketch of the scaled drawings

Since the internal angle sum of a triangle is 180 degrees, and the angles are in ratio if 1:1:4, the angles with that's corresponding to the 1 will have value of 180/6=30 degrees.

The largest angle will have value 30*4=120 degrees.

This is an obtuse triangle because largest angle>90 degrees.

2.A chemist needs to mix a 12% acid solution with a 32% acid solution to
obtain an 8‐liters mixture consisting of 20% acid. How many liters of each of
the acid solutions must be used?

Answers

9514 1404 393

Answer:

1012%: 4.8 L; 32%: 3.2 L

Step-by-step explanation:

For mixture problems, I like to use a single variable to represent the quantity of the greatest contributor (greatest cost or greatest concentration). Let that variable be x.

1. In this problem, the amount of the greatest contributor is already fixed, so we'll use x for the amount of walnuts. The cost of the mix is ...

  0.80x + 1.25(8) = 1.00(x +8)

  2 = 0.2x . . . . . . . . . . . . . . . . . subtract 0.8x+8, simplify

  10 = x . . . . . . . . . divide by 0.2

10 pounds of walnuts must be used.

__

2. The amount of acid in the mix is ...

  12%(8 -x) +32%(x) = 20%(8)

  20%(x) = 8%(8) . . . . . . . . . . . . subtract 12%(8)

  x = 8(8)/20 = 3.2 . . . . . . . . . . divide by 20%

  8-x = 4.8

3.2 liters of 32% acid must be mixed with 4.8 liters of 12% acid

Comment on mixture problems

The general solution for mixture problems that have a greater contributor (G), a lesser contributor (L), and a mix value (M) is ...

  g/l = (M -L)/(G -M) . . . . . . ratio of quantities of G and L

In the first problem, this becomes ...

  8/l = (1.00 -.80)/(1.25 -1.00) = .2/.25 = 4/5  ⇒  l = 8(5/4) = 10

In the second problem, this becomes ...

  g/l = (20-12)/(32-20) = 8/12 = 2/3  ⇒  g = (2/5)(8) = 3.2; l = (3/5)(8) = 4.8

In this case, we recognize that the ratio of 2 parts to 3 parts means that the greater contributor is 2 of 5 total parts.

What is the solution to -2|2.2x - 3.3| = -6.6?
O x=-3
O x=3
O x=-3 or x = 0
O x = 0 or x = 3

Answers

Answer: x = 0 or x = 3

The solution to the equation,  -2|2.2x - 3.3| = -6.6, which contain an absolute value, is: D. x = 0 or x = 3.

What is the Solution of an Equation with an Absolute Value?

To determine the solution, we have to isolate the value and find its value.

Given the equation, -2|2.2x - 3.3| = -6.6:

-2|2.2x - 3.3| = -6.6

2.2x + 3.3 = 3.3

2.2x = 3.3 - 3.3

2.2x = 0

x = 0/2.2

x = 0

Or

2.2x - 3.3 = 3.3

2.2x = 3.3 + 3.3

2.2x = 6.6

x = 6.6/2.2

x = 3

The solution is: D. x = 0 or x = 3
