Which transformation can be used to show that LMN is similar to PQR?
A. Dilation, reflection
B. Reflection, translation
C. Rotation, dilation
D. Translation, rotation

Answers

Answer 1
dilation and rotation.

Explanation:
Rotations, reflections and translations are known as rigid transformations; this means they do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.

Dilation, however, are not rigid transformations, since they change the size of a shape. Dilation would not change the shape, just the size; the angle measures would be the same, and the ratio of corresponding sides would be equal to the scale factor used in the dilation. This would give us a similar, but not congruent, figure.

You have researched your dream around-the-world vacation and determined that the total cost of the vacation will be $39,000. You feel you can earn an APR of 10.5 percent compounded monthly and plan to save $485 per month until you reach your goal. How many years will it be until you reach your goal and enjoy your well-deserved vacation?

Answers

Answer:

41.8 years

Step-by-step explanation:

From

[tex]A = P(1+r/n)^{nt}[/tex]

A= 39000

r = 10.5%

P = $ 485

n=12

t = the unknown

t= [ ln(A) - ln(P) ] / n[ln(1 + r/n)]

t= ln 39000 - ln 485/ 12[ln(1+0.105/12)]

t= 10.57 - 6.18/0.105

t= 41.8 years

Please help me out with my homework! This is super urgent! It's due in 18 minutes! Baranga lives in the city of Delmarville, North Carolina. She drives for 572 miles to Montgomery, Alabama. She drove for 22 hours. How long did she drive every hour?

Answers

Answer:

26 miles every hour

Step-by-step explanation:

she drove 572 miles for 22 hours

???????                      for 1 hour

572/22= 26 miles per hour

Answer: 26 miles

We know that Baranga drove 572 miles in 22 hours. To find how much she drove every hour, we must divide.

Let m represent miles, and h represent hours.

m ÷ h = 26

Remember to always check your answer.

26 x h = m

Therefore, the answer is 26. Hope this helps you!

−9x+5<17 and 13x+25<−1 solve for x

Answers

-9x + 5 < 17

Subtract 5 from both sides:

-9x < 12

Divide both sides by -9, and because you are dividing by a negative value the inequality sign gets reversed:

X > -12/9

Simplify:

X > -4/3

13x + 25 < -1

Subtract 25 from both sides:

13x < -26

Divide both sides by 13:

X < -26/13

X < -2

variation, write the equation so you can answer the question. If y = 4 when x = 2,
find y when x = 16.*

Answers

Answer:

32

Step-by-step explanation:

Given, y varies directly as x. So, y=kx, where k is the constant of proportionality.

Given, x=2, y=4. plug in the values in the equation.

4=k*2

k=4/2

k=2

x=16

y=2*16

y=32

Think about the methods you have for comparing two probabilities to decide which is greater. In your Learning Log, create an example and explain two different strategies for comparing probabilities. Title this entry "Comparing Probabilities" and label it with today's date.

Answers

Answer:

Step-by-step explanation:

Probabilities are basically values determining how likely something is to happen. These values are usually represented in fractions or percentages which are the two main strategies as well for comparing probabilities. For comparing probabilities through fractions we would try to make sure the denominators are equal and then compare the numerators. The higher numerator is the probability with the highest chance of something happening. For example...

[tex]\frac{3}{4} > \frac{1}{4}[/tex]  ... 3/4 is a much higher probability than 1/4

The second strategy would be using percentages in the same way. The higher percentage is the one with the highest probability while the lower percentage is the one with the lower probability.

RUNNING OUT OF TIME

Answers

90 minutes

First, we see that at 0 minutes, the container is completely full at 900ml. If you look on the graph, you can see that the container is at 800ml after 10 minutes. This is key because it tells us that the container leaks 100ml every 10 minutes. We can then figure up that 900, when losing 100ml every 10 minutes, will eventually run dry after 90 minutes. You can set up a proportion to check your work, which would look like this: 10 over 100 is equal to x over 900.

Step-by-step explanation:

Given the following :

Number of sugar cookies = 42

Number of Oatmeal = 30

To package the cookies into identical containers so that each container has the same number of cookies with no left over ;

We find the greatest common factor of 42 and 30

Factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42

Factors of 30 : 1, 2, 3, 5, 6, 10, 15, 30
