25% of the 180 cars are red. How many cars are red?

2 answers:

8 0

Hey there!

This is the formula I use
p(percent) over 100= is/of

25/100= x/180= 180*25 = 4500/100= 45

45 of the cars were red

Answer:

see explanation

Step-by-step explanation:

given that V is directly proportional to u and inversely proportional to f , then the equation relating them is

V = $\frac{ku}{f}$ ← k is the constant of proportion

(a)

to find k use the condition when u = 1 and f = 3 , V = $\frac{1}{6}$ , then

$\frac{1}{6}$ = $\frac{k}{3}$ ( cross- multiply )

6k = 3 ( divide both sides by 6 )

k = $\frac{3}{6}$ = $\frac{1}{2}$

V = $\frac{u}{2f}$ ← equation of proportion

(b)

when f = 4 and V = 1 $\frac{1}{4}$ = $\frac{5}{4}$ , then

$\frac{5}{4}$ = $\frac{u}{2(4)}$ = $\frac{u}{8}$ ( cross- multiply )

4u = 40 ( divide both sides by 4 )

u = 10
