There are 35 females performed in a dance recital.The ratio of men to women is 3 : 8. How many men are in the dance recital
Ipatiy [6.2K]

Answer:

13 or 13.125 you have to look at your notes to see which it is. Personally I would take 13. Try that first.

Step-by-step explanation:

Be careful how you interpret this question. It reads like this.

3:8 :: x:35

In other words, the 8 and 35 females goes together.

Set this up as a proportion

3/8 = x / 35  Cross multiply

3*35 = 8x     Combine the left

105 = 8x       Switch

8x = 105        Divide by 8

x = 105 / 8     get the answer

x = 13.125       You cannot have 1/8 of a person. So what are you going to do?

You have to round down. x = 13. How close is this

13/35 = 0.371 as apposed to 0.375 which is what 3/8 is.

Find the x - and y - intercepts of the line. X + 3y=6Y intercept: ( , )X intercept: ( , )
pantera1 [17]

ANSWER:

Y intercept: (0, 2)

X intercept: (6, 0)

STEP-BY-STEP EXPLANATION:

We have the following equation:

x+3y=6

The x-intercept is when y is equal to 0 and the y-intercept is when x is equal to 0, therefore:

\begin{gathered} \text{ x-intercept } \\ x+3\cdot0=6 \\ x=6\rightarrow(6,0) \\ \text{ y-intercept } \\ 0+3\cdot y=6 \\ y=\frac{6}{3}=2\rightarrow(0,2) \end{gathered}
