Answer: L = 29cm
Step-by-step explanation:
Let's go!!
To find any rectangle area, you have to apply this formula: A = L . w , where L is the length and w is the width.
So, we have w = L - 13 (the width is 13 less than the Length) and then, perimeter is 90 cm.
Well, I hope you remember that the perimeter of rectangle is 2L + 2W. In this case, 2L + 2w = 90
Then, you might to solve this system of equation:
2L + 2w = 90
w = L - 13
Simplifying the first equation, you'll have L + w = 45 (you can divide everything of 2).
Our new system:
L + w = 45
w = L - 13
Using the substituition method:
L + L - 13 = 45
2L = 58
L = 29 cm
the width is 29 - 13 = 16 cm
Answer:
3000
Step-by-step explanation:
it is very simple as the number's hundredth place is more than 5 , hence , it will be rounded up to nearest greater number.
in our case, it is 3000

Answer:
The kit has 10 different colors of beads.
There are 10 beads of each color.
This means that we have 10*10 = 100 beads in total.
We know that she uses 5 beads in a project, and then to complete it she uses other 43 beads.
Then the total number of beads used is:
43 + 5 = 48 beads.
Then the remaining number of beads is:
100 - 48 = 52
