Ignore the decimal places and do 789x38 and you get 29982. Now all you have to do is put the decimal places back. Since 789 was 7.89 it had 2 decimal places and 38 had 1 you have to move 29982 three decimal places to the left making your final answer 29.982.

73. If 65% of x is 130, what is the value of x? A. 84.5 B. 130 C. 165 D. 200 E. 260

MrRissso [65]

Answer:

D) 200

Step-by-step explanation:

To find what x equals you have to use the expression:

is over of equals percent over 100

In this problem you are given the percent, 65%, and the is, 130.

So we are trying to find the of so you would substitute of with x.

So 130/x = 65/100

Now you would do Cross Product Property to find x.

So 130*100 = 13000

65*x = 65x

65x = 13000

65/65 = 1

13000/65 = 200

x = 200

So 65% of 200 is 130

Kitty [74]

Answer:

300

Step-by-step explanation:

Students like Vanilla ice cream = 86

Out of 86 Students like chocolate ice cream too = 48

So, No. of students who like only vanilla=86-48 = 38

There were 12 students who did not like vanilla ice cream but liked chocolate ice cream.

There were 2 students who did not like either vanilla ice cream or chocolate ice

Like Vanilla Did not like vanilla Total

Like Chocolate 48 12 60

Did not like chocolate 38 2 40

Total 86 14 100

No. of students who like chocolate out of 100 = 60

Now we are supposed to find the number of students who would like chocolate ice cream when 500 high school students participate in the survey.

Let x be the number of students out of 500 who like chocolate

So, A.T.Q

$\frac{60}{100}=\frac{x}{500}$

$\frac{60}{100} \times 500=x$

$300=x$

Hence the number of students who would like chocolate ice cream when 500 high school students participate in the survey is 300.
