Answer:

Well, I'm not really sure what to do, but if you just need the numbers to multiply to get the latter numbers in the question they are: 10/11 (for the first question) and 81/80 for the second.

Step-by-step explanation:

For Question #1: You just multiply 5/11 by two to get the number that 1/2 has to multiply to get 5/11. And 5/11 * 2 is 10/11. So I guess the answer is 10/11...

For Question #2: The common denominator for them both is 180, and 4/9 times 81/ 80 is what 80/180 (4/9) has to multiply by to get 81/180.

I used the equation 4/9x=9/20

Multiplied the 9 and then divided by 4 to get the answer, which was 81/80.

***I also noticed, that 1/2 is 1/22 away from 5/11, and 4/9 is 1/180 away from 9/20.

Hope this helps!

Answer:

1) >

2) <

Step-by-step explanation:

1/2 , 5/11

Convert into same denominator using lcm: which is 22

1/2 = 11/22

5/11 = 10/22

11/22 > 10/22

1/2 > 5/11

4/9 , 9/20

Lcm: 180

4/9 = 80/180

9/20 = 81/180

80/180 < 81/180

4/9 < 9/20

Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.
Allisa [31]

Answer:

21

Step-by-step explanation:

Given,

  • Number of red marble = 4
  • number of green marble = 3
  • number of transparent marble = 1
  • number of yellow marble = 3
  • number of orange marble = 3

Total number of marble except red and green  = 3 +3+1

                                                                               = 7

So, the total number of possible sets of five marbles such that none of them are green or red can be given by

n\ =\ ^7C_5

   =\ \dfrac{7!}{(7-5)!.5!}

   =\ \dfrac{7!}{5!.2!}

  =\ \dfrac{42}{2}

   = 21

So, the required number of possible sets are 21.

What is the slope represented in the table ?
Natasha_Volkova [10]

Answer:

slope:2

Step-by-step explanation:

Slope is rise/run, or change in y/change in x.

With that being said, we only need two points to solve this.

Let's take the points (0,7) and (1,9)

The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).

M is the slope.

y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.

x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.

Plugging those values in to the formula, we get m=(9-7)/(1-0)

Simplifying, we get m=2/1, which is m=2.
