Answer: attending the game

Step-by-step explanation:

Given: 12 out of the first 48 people who entered the stands were wearing a coat.

That means, Proportion of people wearing coat = $\dfrac{12}{48}=\dfrac{1}{4}$ (People wearing coat divided by Total people)

Total people in the sample attending the game= 200

Number of people wearing a coat = $200\times\dfrac14$

$=50$

at the elementary school fun fair,the ratio of the number of adults to the number of kids is 4:7. If there are 159 more kids tha

Oxana [17]

the ratio of the number of kids is 4:7

that means for every 7 kids we have 4 adults

7 kids ---- 4 adults

the difference is 3

we dived the difference of the kids between the difference of the ratio

150/3 = 50

the number we obtained must be multiply by the ratio of each part

7(50) = 350 number of kids

4(50)=200 number of adults

there are 200 adults at the fun fair

Suppose y varies directly as x, and y=14 when x=4. What is the value of y when x=9

Katena32 [7]

Given :-

y varies directly as x, and y=14 when x=4.

To Find :-

the value of y when x=9 .

Solution :-

According to Question ,

y = kx ( k is constant )

When y = 14 and x = 4 ,

14 = k(4)
k = 14/4
k = 7/2

When x = 9 ,

y = 7/2*9
y = 63/2
y = 31.5

(4x10^2) - (2x10^-1)

balandron [24]

Answer:

Step-by-step explanation:

The LCD here is 10.

Multiplying numerator and denominator of (4*10^2) by 10 results in:

40*10^3

-------------

10

and rewriting (2x10^-1) with positive exponent in the denominator results in:

2

---------

10

So, before simplification, this difference comes out to be:

40000 - 2 39998 19999

----------------- = ---------------- or ------------
