Answer:
83 cm
Step-by-step explanation:
Let the length of the rectangle be L cm and the width be W cm.
L= 2W +3 -----(1)
Perimeter of rectangle= 2(length) +2(width)
2L +2W= 246 -----(2)
Substitute (1) into (2):
2(2W +3) +2W= 246
Expand:
4W +6 +2W= 246
Simplify:
6W +6= 246
Divide both sides by 6:
W +1= 41
W= 41 -1
W= 40
∴ width of the rectangle is 40cm.
Substitute value of W into (1):
L= 2(40).+3
L= 80 +3
L= 83
Thus, the length of the rectangle is 83 cm.
Y= -6
and
x= 8
i hope that helps :)
Answer:
B
Step-by-step explanation:
A cylinder is like circles staked on top of each other so you want to find the are of the top circle which is 28.26 because pi r^2 (3^2)*3.14. now you found the area of the top circle. The height is 10.5 so that means there are 10.5 layers so you multiply 28.26 by 10.5 i know its confusing im new to brainly but hopefully this answer helped you You will get 296.73 because i rounded pi to 3.14 but the answer is B
Gary can take 1 sheet of stickers and 13 single stickers
Jill can take 1 sheet of stickers and 13 single stickers
<em><u>Solution:</u></em>
Given that,
Gary and Jill both wanted 23 stickers for a class project
Which means,
Gary = 23 stickers
Jill = 23 stickers
There are 3 sheets of 10 stickers and 30 single stickers on the table
Therefore,
3 sheets of 10 stickers
Single stickers = 30
Thus we can say,
Gray can take : 1 sheet of sticker (10 stickers ) + 13 single stickers = 23 stickers
Jill can take : 1 sheet of sticker (10 stickers ) + 13 single stickers = 23 stickers
