Answer:
A
Step-by-step explanation:
Answer:
- equation: w +(2w -3) = 18/2
- length = 5 cm
- width = 4 cm
Step-by-step explanation:
Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:
w + (2w -3) = 18/2
3w -3 = 9 . . . . collect terms
3w = 12 . . . . add 3
w = 4 . . . . divide by 3
2w-3 = 2·4 -3 = 5 . . . . length
The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.
Ok so the equation would be
amount = number of bacteria originaly *optional* × 2^(number of minutes divided by 10)
It's the number of minutes divided by 10 because it doubles every 10 minutes.
So if it took two hours for all of it to fill, it would've been 120 minutes so 12 10 minutes.
2^12
So half of that would be 60
I think it takes an hour if you divide it --- the rest is just extra calculation
Answer:
Odd numbers that are multiple of 5 and are in between 22 and 66 are-
25, 35, 45, 55, 65
Let this set be represented by A
A= {25, 35, 45, 55, 65}
the above form represents the set in its roster form
If you bring every horizontal piece down they will cover whole side .also vertical pieces will cover whole side ,too. so 17+17=34
