The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Requiredpercentagevalue = a
total value = b
Percentage = a/b x 100
The number of damagedbluecandies is 4.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Requiredpercentagevalue = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Totalnumber of candies = 60
Number of bluecandies = 20% of 60
This means,
= 20/100 x 60
= 12
The number of damaged blue candies.
= 20% of 20
= 20/100 x 20
= 4
Thus,
The number of damagedbluecandies is 4.

Answer:
7. A
8. C
9. C
10. A
Step-by-step explanation:
You just have to work each one out. This is very simple.
assuming b is the underscript of log, the formula is log _b_3=-8.
the formula for log is usually log_b_x=n, and to convert it to exponential would be the same as b^n=x
just fill in the numbers, b is still b, and -8 will be the in place of n, equal to 3.
b^-8=3
The value of y when x = 5.25 is 210.
Given that the value of y varies directly with x.
When y = 30, x = 0.75.
We need to find the value of y when x = 5.25,
If the value of y varies directly with x, it means that the relationship between y and x can be expressed as:
y = kx
Where "k" is the constant of proportionality. To find the value of "k," we can use the given information:
When y = 30, x = 0.75:
30 = k × 0.75
Now, solve for "k":
k = 30 / 0.75
k = 40
Now that we have the value of "k," we can use it to find the value of y when x = 5.25:
y = k x
y = 40 × 5.25
y = 210
So, when x = 5.25, the value of y is 210.
