The answers are as follows:
Q1: 65%
Q2: 25%
Q3: 46.42%
Q4: No
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.
As per the given data:
The table gives us the data on male, female and total drivers with respect to the car they drive.
For percent of males that drive sports cars:
= (males who drive sports car / total male drivers) × 100
= (39/60) × 100
= 65%
For percent of all drivers that are male:
= (male drivers / total drivers) × 100
= (60/240) × 100
= 25%
For percent of sports car drivers that are male:
= (male sports car drivers / total sports car drivers) × 100
= (39/84) × 100
= 46.42%
Question 1 and question 3 are not the same.
Hence, the answers are as follows:
Q1: 65%
Q2: 25%
Q3: 46.42%
Q4: No

Step-by-step explanation:
for the math problem, the answer is 13.63%.
The number of square feet that she can paint in one hour will be 31.67 square feet per hour.
The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Stefanie is painting her bedroom. She can paint 12 and 2/3 square feet in 2/5 of an hour.
The total number of squares is given as,
Area = 12 + 2/3
Area = 38/3 square feet
Then the number of square feet that she can paint in one hour is given as,
Rate = (38/3) / (2/5)
Rate = (38 x 5) / (2 x 3)
Rate = 31.67 square feet per hour
The number of square feet that she can paint in one hour will be 31.67 square feet per hour.
More about the rate link is given below.

Answer:
31 2/3 .
Step-by-step explanation:
To find how many square feet Stefanie can paint in one hour, divide the number of square feet by the fraction of an hour:
12 2/3 divided by 2/5 = 38/3 divided by 2/5.
=38/3 times 5/2
=190/6
=31 2/3 .
y = x - 4 2x + y = 5
next set is
x + 4y = 6 y = -x + 3
next set is
x + 2y = 6 x - y = 3
next set is
3x - 2y = 9 y = 2x - 7
{y = x - 4
=> 2x+x-4=5 => 3x=9......x=3
{2x + y = 5 y=3-4=-1
