Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of
amount of peas picked by Rim
Given:
Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.
To find:
The percentage increase of amount of pears picked by Kim.
Solution:
We know that,
[tex]\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{287-250}{250}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{37}{25}\times 10[/tex]
[tex]\%\text{ increase}=\dfrac{370}{25}[/tex]
[tex]\%\text{ increase}=14.8[/tex]
Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.

Formula:
Louis wants to carpet the rectangular floor of his basement. The basement has an area of 2,000 square feet. The width of the basement is 4/5 its length. What is the length of Louis's basement?
Answer: 50 feet
Step-by-step explanation:
Let the length be represented by x
The width of the basement is 4/5 its length. Therefore, the width is 4/5x = 0.8x
Area = Length × Breadth
2000 = x × 0.8x
0.8x² = 2000
x² = 2000/0.8
x = ✓2500
x = 50
Therefore, the length is 50feet
Tonka weighs 100 pounds. He is loading a freight elevator with
identical 50 pound boxes. The elevator can carry no more than
2000 pounds. How many boxes can Tonka load onto the elevator?
50x + 100 = 2000
O 50x - 100 = 2000
100x + 50 = 2000
100x - 50 = 2000
38 boxes

Find the slope of the line from a graph. Will give brainliest!!!
Answer:
2/1 or 2
Step-by-step explanation:
to find the slope you have to calculate the rise over run, do this by picking two spots on the line that go thourgh the corner of a square. then count the amount up the is your rise then the lateral movement, the is your run.
this means the answer is 2/1 that can be simplified to 2.

Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
[tex] \sin(45) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(45) = \frac{3 \sqrt{2} }{x} [/tex]
[tex](x) \sin(45) = \frac{3 \sqrt{2} }{x} (x)[/tex]
[tex](x) \sin(45) = 3 \sqrt{2} [/tex]
[tex] \frac{(x) \sin(45) }{ \sin(45) } = \frac{3 \sqrt{2} }{ \sin(45) } [/tex]
[tex]x = \frac{3 \sqrt{2} }{ \sin(45) } [/tex]
[tex]x = 6[/tex]
can someone please help me? it would mean so much to me. thanks a lot!
Answer:
Maybe -3
Step-by-step explanation:
I am not 100% sure but it is better than nothing,
since 3+3=6 I think after 3 is 6, and after 6 is 9. I think that because the more right the line goes you add 3 to every move. So therefore, 3-3=0, and 0-3= -3
Hope this helps. Also, I hope I gave you the correct answer.

A plane descended an average of 200 feet per second for 15 seconds. How far had the plane descended at the end of the 15 seconds?
Answer:
3000 ft
Step-by-step explanation:
If we're going 200 ft per one second, that means, to find the distance after 15 seconds, then we have to multiply:
200 fps (feet per second) x 15 seconds = distance.
Distance = 3000 ft
