Circle Q has center (10,10) and a radius of 2. Circle Q' is formed by dilating Circle Q by a factor of 1/2, which statement is true?
I NEED HELP ASAPPPP PLSS!!!!

Answers

Answer:

(a) Describe the rule for translating center Q onto center P.

center P(2, 0)

center Q(0, 4)

you would need to add 2 units in x axis, and subtract 4 units on y axis.

(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P.

P radius 20, Q radius 2, radiusQ*10 = radiusP, so the scale factor is 10

(c) Are circles P and Q similar? Explain your answer.

they are similar because a similarity transformation (translation, dilation) exists between them

Step-by-step explanation:

Circle Q' is formed by dilating Circle Q by a factor of 10.

What is the scale factor?

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

To Describe the rule for translating center Q onto center P.

center P(2, 0) and center Q(0, 4)

We would need to add 2 units on x-axis, and subtract 4 units on y-axis.

To find the scale factor for dilating circle Q ,so that it has the same radius as circle P.

P radius 20, Q radius 2, radius Q x 10 = radius P, so the scale factor is 10

It is found that they are similar because a similarity transformation (translation, dilation) exists between them.

The answer choices to this question do not make sense since probability is a measure that is always <= 1.0

Based on the number of times a particular colored tile is drawn we can assume that at the minimum there are 6 green, 20 red, 7 blue, 8 purple and 4 black tiles

Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45

The Smiths have a​ rectangular, above-ground swimming pool. The manufacturer says that the pool holds​ 14,040 gallons of water when filled to capacity. After it is​ filled, Mr. Smith follows the​ manufacturer's recommendation of adding 1 ounce of chlorine for every​ 2,700 gallons of​ water, every other day. About how many pounds of chlorine will Mr. Smith add to the pool in 3​ weeks?

Answers

Answer:

54.6 ounces

Step-by-step explanation:

14,040/2,700=5.2

3 weeks is 21 days

21 days divided by 2 because every other day is 10.5 days

5.2 times 10.5 is 54.6

54.6 ounces because 14,040 divided by 2,700 you will get 3 week and the 21 days so you would do is 21 days divided by 2 because every other day is 10.5 days. So, than 5.2 *10.5 is 54.6.

FInd the area of the parallelogram. 14.3 cm. 12 cm. 18.4 cm.

Answers

You didn’t state which one of these numbers is the base and the height which is needed to solve this problem.

If 14.3 is the base, and 12 is the height, then you multiply them and get the answer.
14.3 x 12 = 171.6

If 14.3 is the base and 18.4 is the height, multiply them.
14.3 x 18.4 = 263.12

So depending on which one is the base, or the height, the answer would be one of those two.

For your understanding of problems like this, the formula for solving the area of a parallelogram is base times the height.

it would probably be answer 1, the one at the top.

Step-by-step explanation:

So, if you gather -1/2 and then flip which makes -2/1 to cancel it out, then you do the same with -16, and then put -16/1(-2/1) then multiply -16 and -2, which will give you 32. Because the equation is now p<32, it would be an open circle going to 32 or higher. Hope this helps, and if sorry if this is wrong, It's been a while since I've revisited this subject!

A. 1 1/2 pounds

B. 1 1/8 pounds

C. 4 1/2 pounds

D. 4 7/8 pounds

Answers

Answer:

B. 1 1/8 pounds

Step-by-step explanation:

What we know:

6 Pounds of meat in total

3 1/8 pounds of ground beef

1 3/4 pounds of sausage

Combining the pounds of ground beef and sausage together:

3 1/8 + 1 3/4 = 4 7/8

In all he has 6 pounds of meat. He we know the combined weight of the ground beef and sausage combined: 4 7/8 pounds. Therefore, the equation is...

6 - 4 7/8 =

The answer is...

B. 1 1/8 pounds

Answer:

B. 1 1/8 pounds.

Step-by-step explanation:

Let the weight of turkey he bought  be x pounds.

Then we have the equation:

x + 3 1/8 + 1 3/4 = 6

x = 6 - 3 1/8 - 1/ 3/4

Converting to improper fractions

x = 6 - 25/8 - 7/4

We could use a calculator to do this but it also can be done manually by converting all amounts to fractions with denominator 8:

x =  48/8 - 25/8 - 14/8

   =  9/8

    = 1 1/8 pounds.
