Solve using a proportion and an equation. Kendra found the experimental probability of her making a penalty kick in soccer is 3/10 or 30%. Out of 40 penalty kicks, how many could she predict she will make?
Answer: The predicted number of penalty kicks = 12
Step-by-step explanation:
Given : The experimental probability of her making a penalty kick in soccer is 3/10 or 30%.
So, the proportion of penalty kicks she make = 0.3
Out of 40 penalty kicks, the predicted number of penalty kicks = 0.3 x 40
= 12
Hence, the predicted number of penalty kicks = 12

A baker made 9 cupcakes, each a different type. Four people want to share them equally. How many cupcakes will each person get? DIvide and use in fraction form.
Answer: 2 1/4
Step-by-step explanation:
From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.
To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:
= 9 ÷ 4
= 2 1/4 cupcakes
Therefore, each person gets 2 1/4 cupcakes.
what is the original price when the discount is 25% and the sale price is $40
Answer:
the original price was $53.33
Step-by-step explanation:
$x ---- 100%
$40 ------- 75% (this is because 25% of it's just 75% of the actual price)
[tex]75\cdot x = 100\cdot 40\\\\75x = 4000\\\\x=53.33[/tex]
===============================================
Work Shown:
x = original price
25% = 25/100 = 0.25
25% of x = 0.25x = discount, or amount saved
final price = (original price) - (discount)
final price = (x) - (0.25x)
final price = 0.75x
0.75x = 40
x = 40/0.75
x = 53.333333
x = 53.33
The original price is $53.33
The discount, or amount saved, is 0.25*x = 0.25*53.33 = 13.3325 = 13.33 dollars.
This means the sale price is 53.33 - 13.33 = 40
We can also see this through computing 0.75*x = 0.75*53.33 = 39.9975 = 40, which matches with the given sale price.
Note how I'm rounding to the nearest penny when needed.

Which list of fractions is in order from smallest to largest? 1/6,1/3 ,1/2 ,1/2 ,1/3 ,1/6 ,1/6 ,1/2 ,1/3, 1/2, 1/6, 1/3
Answer:
The smallest order of fractions in that order would be,
Step-by-step explanation:
1/6, 1/3, 1/2
because the bigger the denominater, the larger the whole is, and in 1/2, it would be equivalent to half, but 1/6 would be smaller. Let's say if it were 3/6, it would be equivalent to 1/2 because its half right? so thats another way you can tell how one fraction is smaller than another.
1/6,1/3,1/2 is the list of fractions is in order from smallest to largest.
What is Fraction?A fraction represents a part of a whole.
The given three fractions are 1/6, 1/3 and 1/2.
We need to order them smallest to largest.
Let us make the denominator same for all the three fractions to compare which is larger and smaller.
1/6×2/2=2/12
1/3×4/4=4/12
1/2×6/6=6/12
So 1/6 is smaller, 1/2 is bigger.
We know Arranging numbers in increasing order, that is, from smallest to largest is known as ascending order.
by using ascending order we can order the fractions like 1/6,1/3,1/2.
Hence, 1/6,1/3,1/2 is the list of fractions is in order from smallest to largest.

The function t=f(S) models the time, in hours, for a sample of water to evaporate as a function of the size S of the sample, measured in millimeters. What are the units for f’’(S)?
Given that,
The function is t = f(S).
To find,
The unit of f''(S).
Solution,
The given function shows the time for a sample of water to evaporate as a function of the size S of the sample, measured in millimeters.
f'(S) will be in hours per Mililiter
And
f''(S) will be in hours per Mililiter per Mililiter. Therefore, this is the required solution.
