Answer:

Movie Rental B is better to buy. It's cheaper by .75 cents.

Step-by-step explanation:

Solving Movie Rental A

To find the unit rate of this one, we divide the dollars and the rentals.

So, 15 ÷ 3 = 5

Unit Rate for Movie Rental A is 5

Solving Movie Rental B

Same as Movie Rental A, divide the dollars and the Rentals.

8.5 ÷ 2 = 4.25

The number with the less amount is cheaper so

4.25 is less than 5

Answer:

24

Step-by-step explanation:

We are given a strand of numbers and are asked to find the mode.

To find mode, we have to see which number appears the most within the number strand, let's start with ordering the numbers from least to greatest.

20, 22, 23, 24, 24, 25, 46

Looking at the strand we see that 24 appears the most, therefore 24 is the mode.

Answer:

24

Step-by-step explanation:

Put the numbers in order.

20, 22, 23, 24, 24, 25, 46

Count how many of each number.

20

22

23

24, 24

25

46

The number that appeared the most is the mode.

24 appeared twice and the other numbers appeared only once.

7/2 = 35/10 & 3/5 = 6/10

Step-by-step explanation:

This is very hard to be explained, sorry.

Answer:

The first one:   35/10

Second:   6/10

Step-by-step explanation:

These are the answers because since you are trying to solve to get a denominator of 10, you must multiply both the to and bottom numbers by whatever you need to get the denominator to 10.  For example, for 3/5 you would multiply both the top and bottom numbers by 2, because you nned to multiply the denominator by 2 to get 10.

I am so sorry I dont get it

Answer:

-12 degrees

Step-by-step explanation:

Fahrenheit and Celsius

10 degree fahrenheit

What is the celsius?

____________________

Take a look at the picture with the information provided, we see that f is the vertical line while c is the horizontal line. Since we are looking for 10 degree fahrenheit, let's find it on the vertical line. If we look at the red line, when it goes across 10 fahrenheit, the approximate part that it hits celsius is -12 degrees.

Answer:

Step-by-step explanation:

190 ppl

40 ppl per 4 cab

10 ppl per cab

10 times 19 cabs = total of ppl

So If Hannah weighed 7.2 lb at birth during the six months that are shown on the table hanna puts on 8.7 during those six months so if we’re estimating what her weight will be at her one year visit

8.7(what she put on during the six months)+ 15.9 (her weight now)= 24.6

Answer: I estimate she will weigh 24.6lb at her one year visit

Hope this helps

Answer:

The woman walks at 2.5 mph.

Bonus: she rides her bicycle at 12.5 mph.

Step-by-step explanation:

We're told that she can bicycle 25 miles in the time takes her to walk 5.  That means that on a bicycle, she moves 25 ÷ 5, or 5 times faster on a bicycle than when she runs.

We're also told that she can ride at 10 mph faster than she can walk.

That gives us two relationships to describe.  If we call her speed on the bicycle "b", and her speed on foot "w", then we know:

b = 5w

and

b = w + 10

Since both of those describe b, we can simply equate them.  Stating the obvious:

b = b

therefore:

5w = w + 10

We can then simplify:

5w = w + 10

4w = 10

w = 2.5

So she walks at 2.5 miles per hour.

We can test that answer too.  Let's compare to the first statement, her bicycling 25 miles in the time it takes to walk five miles.

Walking 2.5 miles per hour means she'd take two hours to walk five miles.

We also know that she can ride 10mph faster, so she rides at 12.5 mph.  two times that is 25, so she would indeed cover 25 miles on her bicycle in the same time that she walks five.

D. Horizontally compressed by a factor of 1/3

[tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]

Option D is correct

Note that:

If a function [tex]f(x)=Asin(x)[/tex] is transformed to [tex]g(x)=Asin(kx)[/tex], it means that the function f(x) is horizontally compressed by 1/k

Relating this rule to the given function [tex]f(x)=\frac{1}{2}sin(x)-4[/tex]

If x is replaced with 3x, the function will become:

[tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]

This means that the graph of  [tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]
