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.

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 .
Answer:
The net change in total sales was sale is decreases by 40.
Step-by-step explanation:
Sale of shop on Monday = $2,000
On Tuesday sales of shop fell by 10%
∴ Sales of shop on Tuesday = $2,000 × (100-10)% = $1,800
On Wednesday sales of shop fell by 20% of Tuesday's sale
∴ Sales of shop on Tuesday = $1,800 × (100-20)% = $1,440
On Thursday sales of shop increased by 25% of Monday's Total sale
∴ Sales of shop on Thursday = $1,440 + (25 × 2000)% = 1440 + 500 = $1,940
The net change in total sales was sale is decreases by 40.
What is the missing output value?
The missing output value is:
9
The function in terms of the variable x, where x represents the input value is given by the formula:
where F(x) is the output value corresponding to the input value x.
We are asked to find the missing output value i.e. we are asked to find the value of F(x) at x=5.
i.e. we have:
Hence, the missing output value is: 9

Answer:
The Third Choice
Step-by-step explanation:
In this question, we have to compare the sine of angle A and the cosine of angle B. As a review, the sine function is
and the cosine function is
.
For angle A, side BC is the opposite side, while side AB is the hypotenuse. [The hypotenuse of a right triangle is the side that is opposite to the 90 degree angle. In this case, AB is the hypotenuse because it is opposite of angle C, which measures 90 degrees.]
Now, we can determine the sine of angle A.
.
For angle B, side BC is the adjacent side, while side AB is the hypotenuse.
Using this information, we can determine the cosine of angle B.
As we can see, both the sine of angle A and the cosine of angle B have the same value. In other words, they are equal to each other. Therefore, the correct answer is the third choice.
