A square of side x is cut out of a larger square of side y. What is the area of the remaining
figure?
Answers
Answer:
The area of the remaining figure is [tex]y^2-x^2[/tex]
Step-by-step explanation:
Area of the Square Shape
Given a square of side length x, the area is calculated by the formula:
[tex]A_x=x^2[/tex]
It's given a square of side x is cut out of a larger square of side y. Please refer to the image below.
The area of the square of side length y is:
[tex]A_y=y^2[/tex]
The shaded area of the remaining figure is the difference between both areas:
[tex]A=A_y-A_x[/tex]
[tex]A=y^2-x^2[/tex]
The area of the remaining figure is [tex]\mathbf{y^2-x^2}[/tex]
The stopping distance (s) of a truck varies directly as the square of its speed (v). If a truck travelling at 50 mph requires 200 feet to stop, find the stopping distance for a truck travelling at 65 mph.
Answers
Answer:
The distance is 338ft
Step-by-step explanation:
Given
Represent distance with s and velocity with v:
When
[tex]s = 200\ ft[/tex]
[tex]v = 50mph[/tex]
Required
Determine the distance when velocity is 65mph
From the question, we understand that:
[tex]s\ \alpha\ v^2[/tex]
Convert to equation
[tex]s\ = kv^2[/tex]
Substitute 200 for s and 50 for v
[tex]200 = k * 50^2[/tex]
[tex]200 = k * 2500[/tex]
Make k the subject:
[tex]k = \frac{200}{2500}[/tex]
[tex]k = \frac{2}{25}[/tex]
To get s when v = 65.
Substitute 65 for v and 2/25 for k in [tex]s\ = kv^2[/tex]
[tex]s = \frac{2}{25} * 65^2[/tex]
[tex]s = \frac{2}{25} * 4225[/tex]
[tex]s = \frac{8450}{25}[/tex]
[tex]s = 338\\[/tex]
Hence, the distance is 338ft

Answers
Answer:
proportional
Step-by-step explanation:
20 : 25 :: 36 : 45
Product of means = 25*36 = 900
Product of extremes = 20 * 45 = 900
Product of means = Product of extremes
So, the number of pages read is proportional to your time

Office Depot prints black and white or colored copies.Yesterday,they printed 9 black and white copies for every 2 colored copies if they print 200 color copies how many black and white copies were printed?
Answers
Answer:
900 black and white copies were printed.
Step-by-step explanation:
From the information provided, you know that they printed 9 black and white copies for every 2 colored copies and you can use a rule of three to find the amount of black and white copies that were printed if they printed 200 color copies:
9 black and white → 2 colored
x ← 200 colored
x=(9*200)/2=900
According to this, the answer is that 900 black and white copies were printed.

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year period, models the population growth. How many foxes will there be after 26 years
Answers
Answer:
640 foxes
Step-by-step explanation:
The actual formula is [tex]y = 40 * 4^{x}[/tex]
Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.
26 / 13 = 2 periods
Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...
[tex]y = 40 * 4^{x}[/tex]
[tex]y = 40 * 4^{2}[/tex]
[tex]y = 40 * 16[/tex]
[tex]y = 640[/tex]
Finally, we can see that there should be 640 foxes after 26 years.

This equation shows how the total amount of paper Shelby's office has recycled depends on the number of weeks since they started the new recycling plan. p = w + 14. The variable w represents the number of weeks the office has been on the new recycling plan, and the variable p represents the total kilograms of paper recycled. How many weeks will it take Shelby's office to recycle a total of 16 kilograms of paper?
Answers
Explanation: Since we know that p represents the amount of paper recycled, we can write the new equation as 16=w+14. When you solve that equation you get an answer of 2=w
