Answer:

width = 10 cm

Step-by-step explanation:

the ratio of width to length is 2 : 5 = 2x : 5x ( x is a multiplier )

the perimeter (P) of a rectangle is calculated as

P = 2 × width + 2 × length

given P = 70 then

2(2x) + 2(5x) = 70

4x + 10x = 70

14x = 70 ( divide both sides by 14 )

x = 5

Then

width = 2x = 2 × 5 = 10 cm and length = 5x = 5 × 5 = 25 cm

Answer:

16/21 dresses

Step-by-step explanation:

3/4 · k hours: 4/7 · k dresses for any constant k

If we want 1 hour, then k will need to be 4/3

4/3 × 4/3 hours: 4/7 × 4/3

1 hour = 16/21 dresses

Virty [35]

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

t² = -175 /-16

t² = 175/16

Here there si two solutions : t = $\sqrt{175/16}$ and t = - $\sqrt{175/16}$

However, as time cannot rewind, we will keep only positive solution

So t = $\sqrt{175/16}$

in seconds it will be : 3.3 seconds
