On Saturday, Mark sold 2 7/8 gallons of lemonade.

On the same day, Regan sold 2/3 as much lemonade as Mark.

How much lemonade, in gallons, did Regan sell?

Answers

Answer:

Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade

Step-by-step explanation:

Operations with Fractions

Mark sold [tex]2\frac{7}{8}[/tex] gallons of lemonade.

Regan sold [tex]\frac{2}{3}[/tex] as much lemonade as Mark

We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:

[tex]2\frac{7}{8}=2+\frac{7}{8}=\frac{23}{8}[/tex]

Now we multiply:

[tex]\frac{23}{8}\cdot \frac{2}{3}=\frac{46}{24}=\frac{23}{12}[/tex]

Find an equivalent fraction to 5/6 only.

Answers:
A) 2/4
B) 10/12
C) 11/6
D) 20/24
E) 50/60

Answers

B), D), and E) are all equivalent fractions to 5/6.
2/4 isn’t because simplified it equals 1/2
11/6 isn’t because it cannot be simplified further
10/2 = 5 and 12/2 = 6, which is why B) is one of the answers
20/4 = 5 and 24/4 = 6, which is why D) is another answer
50/10 = 5 and 60/10 = 6, which is why E) is the third answer

Answer:

B D and E

Step-by-step explanation:

Remark

It's hard to know how to tackle this. I suppose  the easiest way is to divide the numerator and denominator by a common factor.

2/4

The common factor is 2

Divide the 2 by 2 and the 4 by 2

2/2 = 1

4/2 = 2

The fraction reduces down the 1/2 which is not 5/6

10 / 12

The common factor is 2.

10/2 = 5

12/2 = 6

Looks like this is your answer. But is it the only one.

11/6

These two have no common factor. The answer is 11/6 which is not 5/6

20 / 24

The common factor of these two is 4

20/4 = 5

24/ 4 = 6

This is also = to 5/6

50 / 60

The common factor is 10

50/10 = 5

60/10 = 6

That's equal to 5/6 as well.

A fitness club charges a onetime $75 initiation fee plus $30 each month for a member to maintain her membership. Which equation below models the total cost, c, the club charges as a function of the number of months, m, that the individual has maintained her membership?

1) c = 75m + 30
2) c = 1/30m + 75
3) c = 30m + 75
4) c = 900 + 30m

Answers

Answer:

c = 30m + 75

Step-by-step explanation:

Because the 75 dollars is only one time you add that to the total. Because it is 30 dollars PER MONTH and m is the number of months you would multiply those two in order to know how much you would be paying!

CAP has vertices

P-1,-10).

What are the coordinates of the image of
A after the given composition of tranformations?

Dilation: center (0, 0); scale factor 5,
Translation: (x, y) (x-9,y +11).

Answers

Answer:

[tex]A'' = (6, -34)[/tex]

Step-by-step explanation:

Given (Points)

[tex]C = (-3,8)[/tex]

[tex]A = (3,-9)[/tex]

[tex]P = (-1,-10)[/tex]

Transformations:

Dilation: Center (0,0); Scale factor = 5

Translation: (x, y) --> (x-9,y +11).

Required

Determine the image of A

[tex]A = (3,-9)[/tex]

Apply the first transformation:

i.e. dilation by a scale factor of 5

[tex]A'=A * 5[/tex]

[tex]A'=(3,-9) * 5[/tex]

[tex]A'=(3* 5,-9* 5)[/tex]

[tex]A'=(15,-45)[/tex]

Apply the second transformation:

i.e. translation: (x, y) --> (x-9,y +11).

[tex]A'=(15,-45)[/tex]

[tex]A'' = (15 - 9, -45 + 11)[/tex]

[tex]A'' = (6, -34)[/tex]

Hence, the image of A is (6,-34)

e = 4/9

f = 16/81

Step-by-step explanation:

What is the area of the trapezoid?

Answers

78. you can find the area of the two ends which are triangles by subtracting 11 from 15. Then divide that four by two since both ends are included. Multiply 2 by 6 to get half the area of one triangle. But since there are two just leave that number as is. Finally multiply 11 by 6 to get the rest of the area.

Answer:

A=78ft

Step-by-step explanation:

The area of a trapezoid is A=(a+b)/2 *h

a=long base

b=short base

h=height

For your trapezoid, it will look like this:

a=15ft

b=11ft

h=6ft

Let's add those into the equation:

A=(15+11)/2 *6

Okay, let's solve it! Using PEMDAS, we know parenthesis are first.

A=26/2 *6

Now we divide!

A=13*6

Multiply! And don't forget to add your unit.

A=78ft

change 4 and 4 on 9 to an improper fraction ​

Answers

Answer: 40/9

Step-by-step explanation:

First multiply the number 4 and the denominator 9 together which is 36 in this case. Then add the remaining 4 which takes you to 40 then the denominator will stay the same so the answer will be 40/9

4 4/9 you multiply the denominator, 9, by the whole number, 4. (36) Then you add the numerator, 4 to get 40. That’s how many 9ths you have. 40/9.

Because each one of the whole number = 9/9ths

So when we multiply as above, you are adding 9/9 + 9/9 + 9/9 + 9/9 + 4/9. Add the numerators, but the denominator stays the same.
