Answer:

w=6.5cm and l=19.5cm

Step-by-step explanation:

l=3w & p= 52cm

P=2(l+w)

p=2(3w+w)

p=2(4w)

52cm=8w dividing both sides by 8

w=6.5cm

L=3w

L=3(6.5cm)

L=19.5cm

If about 1/40 of the earths water is fresh water. About 3/10 of the earths fresh water is ground water. What fraction of the ear

Alex17521 [72]

Answer:

3/400

Step-by-step explanation:

Let w represent earth's water

let f represent fresh water and let g represent ground water

$f = \frac{1}{40}w$

$g =\frac{3}{10}f = \frac{3}{10}(\frac{1}{40}w)\\ \\g = \frac{3}{400}w$

Therefore, fraction of earth's water,w, that is ground water = 3/400
