Answer: men = 15 , women = 12

Step-by-step explanation:

Ratio of men to women = 5:4

Total ratio = 9

number of people = 27

number of men = ration of men / total ratio x total number of people

That is :

number of men = 5/9 x 27

number of men = 3

Number of women = ratio of women / total ratio x number of people

That is :

number of women = 4/9 x 27

number of women = 12

The class room have 15 men and 12 women.

Step-by-step explanation:

       The given is,

            ratio of  men:women = 5:4

            Total people = 27

Step:1

       Let, X= Men in class,

              Y=Women in class,

Step:2

      For total men in class are,

              ratio for men= \frac{5}{9}                 (∵ 9= 5+4, for men = \frac{5}{9})

      Number of men in class

                        = Total people × Ratio of men

                        = 27 ×  \frac{5}{9}  

                     X =  15

               Men in class, X= 15.

Step:3

      For total women in class are,

                 ratio for women = \frac{4}{9}          (∵ 9= 5+4, for women = \frac{4}{9})

     Number of women in class

                        = Total people × Ratio of women

                        = 27 ×  \frac{4}{9}

                    Y  = 12

                women in class, Y = 12.

Step:4

     Check for solution,

                  Total people = Men + Women

                                         = 15 + 12

                                    27 = 27

Result:

     Men in class are 15 and Women in class are 12. Total number of people in class are 27.

Here's a graph of a linear function. Write the
Kryger [21]

Answer:

<em>y = -3x+4</em>

<em />

Step-by-step explanation:

Slope intercept form of a line is given by  y = mx + b

Where

m is the slope

b is the y intercept.

To find m, we need to take any arbitrary 2 points and see how many units up/down and how many units right/left we need to go from one to another. <em>Basically change in y by change in x.</em>

<em />

Let's take 2 arbitrary points: (0,4)  &  (2,-2)

So we need to go -6 units from y = 4 to y = -2. We need to go 2 units from x = 0 to x = 2.

Hence slope is change in y by change in x, which is -6/2 = -3

b is the y-interceept, the place where it cuts the y axis. Looking at the graph, it is at y = 4

<em>Now we can write the equation as :</em>

<em>y = -3x+4</em>

b. 3(43)+51 =180 51 degrees; 129 degrees

Step-by-step explanation:

3x +51 =180

3x=180-51

3x=129

x=43

Help mee with this question pls I don’t understand
elena-s [515]

Answer:

a) Cat

b) 4 (unless there is a key that says otherwise)

c) 3 more people

Step-by-step explanation:

a) It has the least number of shapes (only 5)

b) Cat has 1 small square which stands for 1 person and 4 small squares put together make a big square so a big square is 4 people. Unless a key says that a small square is more or less 1, then it should be 4.

c) If one big square is 4 people, then there are 10 people for giraffes and 7 people for dogs. 10 - 7 = 3 more people.

Katie is buying souvenir.gifts for her big family back home. She wants to buy everyone either a key chain or a magnet. The magne
NikAS [45]
The total number of gifts = x+y.
The inequality is:
x+y  \geq 24

Key chains cost $1, Magnets $0.50
Total Cost = x + 0.5y
Inequality is:
x+0.5y  \leq 20

Without graphing you can solve system by using substitution:
y = 24 - x  \\  \\ x + 0.5(24-x) = 20   \\  \\ 0.5x +12 = 20  \\  \\ x = 16 \\  \\ y = 24-16 = 8

This is one solution where the maximum x value is given.
So the most keychains that can be purchased is 16. However, because magnets are cheaper, more can be purchased as long as cost remains under 20.

If you solve both inequalities for "y", you get the upper and lower bounds for how many magnets can be purchased given a quantity of keychains.

24-x  \leq y  \leq 40 -2x \\  \\ x \leq 16

This is complete solution which gives all possible combinations.
