Rectangle:
P = 2 (L+W) but length is 2 meters longer than wide
then L = W + 2, So
P = 2 (L + W)
24 = 2(W+2+W)
24 = 2 (2 + 2W)
24 = 4 + 4W
So 4W = 24 -4 =20
W = 20/4= 5, L = 5+2= 7
Double check
24 = 2*(5+7) = 2 *12 = 24
Answer:
25%
Step-by-step explanation:
We need to first convert 3/5th to percentage so we are only dealing with percentage.
3/5 doing division would give us 0.6
Multiply that by 100, we get
0.6 * 100 = 60%
Thus, now we can say:
Walking = 15%
Driving = 60%
The remaining time is cycling. How much?
15 % + 60 % + cycling = 100%
75% + cycling = 100%
Cycling = 100 - 75 = 25%
Answer:
|s -55| ≤ 3
Step-by-step explanation:
"Within 3 mph of 55 mph" means the magnitude of the difference between s and 55 is at most 3. In symbols, this is ...
|s -55| ≤ 3
1.5 is the area which makes it the diameter
Answer:
4.1 billion
Step-by-step explanation:
1 ft = 30.48 cm
1 in = 2.54 cm
The volume of rain that fell on the roof is given by ...
V = LWH
V = (175 ft × 30.48 cm/ft)(45 ft × 30.48 cm/ft)(11 in × 2.54 cm/in)
= 175×45×11×30.48²×2.54 cm³ = 204,412,236.336 cm³
At 20 drops per cm³, this will be ...
20×204,412,236.336 ≈ 4,088,244,727 . . . . raindrops
About 4.1 billion raindrops fell on your roof.
