Answer: 549 meters
Step-by-step explanation:
3 minutes and 3 seconds is the same as:
3 x 60 + 3 = 183 seconds
3 meters per second, multiplied by number of seconds gives us distance:
3 x 183 = 549m
Answer:
Many cannot be counted
Step-by-step explanation:
Step 1
Find the area of one tile
we know that
the area of a square is
where b is the length side of the square
In this problem
Substitute
Step 2
Find the area of the floor
The area of a rectangle is equal to
where
L is the length of the rectangle
h is the width of the rectangle
In this problem
Substitute
Step 3
Find the number of tiles needed
by proportion
therefore
<u>the answer is</u>
Make x the subject
2x = -3y + 1
5x = -2y -3
now times the answers to get the lcd
(2x = -3y + 1) x 5
10x = -15y + 5
(5x = -2y -3) 2
10x = -4y -6
now that they are equal to the same number:
-15y + 5 = -4y -6
-15y + 4y = -6 -5
-11y = -11
y = 1
now to find x we substitute y
2x = -3y + 1
2x = -3(1) + 1
2x = -3 + 1
2x = -2
x = -1
Answer:
(a.) B: 8,000
(b.) C: 800
(c.) A. 10 times
Step-by-step explanation:
8762 has 3 digits after the 8. 8,000 has 3 digits after the 8
851 has 2 digits after the 8. 800 has 2 digits after the 8.
8,000 ÷ 800 = 10
Another way to do it is: 8000 has 3 zeros and 800 has 2 zeros.
3 - 2 = 1. 10 has 1 zero.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
