To find the value of X you would have to solve the equation.

48/100=48%
To find the answer, you would put the total number of boys over the total number of kids who responded to the survey since the question wanted to know what percentage of all the kids were boys. Since the denominator is already 100, we can immediately say that the numerator, or 48, is the percentage of boys who took the survey. The other 52% of the kids were the girls who responded to the survey.

For this, find the value of X for this parallelogram!! Thank you :)

Answer:

$\huge\boxed{\sf x = 12 }$

Step-by-step explanation:

Opposite sides and angles of a parallelogram are equal.

So,

3x - 1 = 35

Add 1 to both sides

3x = 35 + 1

3x = 36

Divide 3 to both sides

x = 36 / 3

x = 12

$\rule[225]{225}{2}$

Hope this helped!

Gina sells 216 cakes in the ratio small :medium:large 5:7:12. The profit for one medium cake is twice the profit for one small c

Rus_ich [418]

To answer this question you need to first set up the small, medium, large number of cakes as a ratio with a total. From here you will create a new ratio of the correct number of small medium and large Cakes sold using the total 216. The factor would be to multiply by nine. -Step 1 in picture. After this you would read what the relationship is between a medium and a small and the large and the small profits are - Step 2 in picture. After this you would represents the total profit based on the number of small medium and large cakes that were sold. Making this equal to L648.45. To find the profit for one small, you would then divide 648.45 by the 495 you got when you simplify the expression. The answer is L1.31.
