1. Determine the scale factor of dilation that maps circle A onto a circle congruent to circle B.
2. Determine the scale factor of a dilation that maps circle B onto a circle congruent to circle C.
3. Determine the scale factor of a dilation that maps circle C onto a circle congruent to circle A.
4. Use your work from #1-3 to determine the scale factor that maps any circle with radius r onto any circle congruent to circle with radius s.

Answers

1 is 3/5
2 is 4/3
3 is 5/4
4 is s/r

The scale factors for each of the given dilations of the circles are;

1) 3/5

2) 4/3

3) 5/4

4) s/r

From the given diagram showing the circles, we see that;

Diameter of circle A = 10

Diameter of circle B = 6

Diameter of circle C = 8

1) Scale factor to map circle A onto a circle congruent to circle B is = new diameter/original diameter = 6/10 = 3/5

2) Scale factor of a dilation that maps circle B onto a circle congruent to circle C = new diameter/original diameter = 8/6 = 4/3

3) The scale factor of a dilation that maps circle C onto a circle congruent to circle A = new diameter/original diameter = 10/8 = 5/4

4) The scale factor that maps any circle with radius r onto any circle congruent to circle with radius s = s/r

Christine has bought 6 bags of chips that she bought for $3.60. How much would it cost if she bought 11 bags of chips?

Answers

The answer is $39.60

By using unitary method, Cost of 11 bags of chips is $6.6.

What is unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Given

Christine has bought 6 bags of chips that she bought for $3.60.

Cost of 11 bags of chips = ?

6 Bags ⇒ $3.60

11 Bags ⇒ X

6X = 11 × 3.60

X = [tex]\frac{11(3.6)}{6}[/tex]

X = [tex]\frac{11(36)}{60}[/tex]

X = [tex]\frac{33}{5}[/tex]

X = 6.6

Thus, Cost of 11 bags of chips is $6.6.

Liz earns a salary of $2,100 per month, plus a commission of 7% of her sales. She wants to earn at least $2,900 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your variable represents. Enter the commission rate as a decimal.

PLS PLS HELP :”)

Answers

Answer:

Her salary of 2600 per month doesn't change, what does change is the amount of money she makes dependent upon her dollar amount in sales. She earns 7% of her sales, which is our unknown. And we know that she would like make at least $2900 this month. That means that it's ok to make exactly 2900 and it's of course ok to make more than 2900 but it's not ok to make less than that. So our inequality sign is greater than or equal to. Now let's set it up as an inequality: where of course, as stated earlier, the unknown is her sales in dollars. It doesn't look like you need to solve this.

Answers

Answer:

Step-by-step explanation:

16 times 0.75 = 12

Answer:

Step-by-step explanation:

75%=3/4.

So, we can simplify it to 3/4 of 16

4/4 of 16 is 16.

So, 3/4 of 16 is 1/4 less than that.

1/4 of 16 is 4. We want 3/4 so we multiply 4*3=12

The amounts below show the change (measured in feet) in water level over four months. What is the
average monthly change in water level?
-0.84, 1.25, -1.59, 0.42

Answers

The average monthly change in the water level is a decrease of 0.19 feet, = -0.19

For an average, we add up the numbers and divide that total by how many “entries” we have.

So 1.25 + 0.42 - 0.84 - 1.59 = 1.67 - 2.43 = -0.76

-0.76/4 = -0.19

17 Kayla wants to give a third of a pie to
each of her 25 relatives. She has
already baked 6 pies. How many
more pies will she need to bake so
that each relative can have a third?

Answers

Answer:

3 more pies

Step-by-step explanation:

If Kayla wants to give 1/3 of a pie to each of her 25 relatives and has 6 pies already, to find the answer first you’d have to find out how many thirds of pies she has already, so,
6 x 3 = 18 slices of pie

(And she needs 25 slices of pie, so,)
25 - 18 = 7 slices of pie

(Turn the 7 slices into pies)
7 ÷ 3 = 2.33

(Kayla needs 2.33 more pies and so If rounded up)
2.33 pies = 3 pies

(Kayla needs)
Answer:
3 pies

What is the slope of the line segment?
answer choices
1/4
1/4

–4

Answers

Answer:

Step-by-step explanation:

To find the slope we can use the slope formula

m = ( y2-y1)/(x2-x1)

We know two points (0,0) and ( 1,4)

m = ( 4-0)/(1-0)

= 4/1

To find the slope you need to see how many times you need to go up therefore on this line segment it’s going by fours so you go up 4 over 1 so the answer would be 4
