Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v

3v+v=4v ; 12v/3v=4v
4v=4v (hope this helps :))

Answer:

$\frac{height\ of\ a\ person}{height\ of\ flower} =\frac{length\ of\ person\ shadow}{length\ of\ flower\ shadow}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

In this problem

$\frac{height\ of\ a\ person}{length\ of\ person\ shadow} =\frac{height\ of\ flower}{length\ of\ flower\ shadow}$

Rewrite

$\frac{height\ of\ a\ person}{height\ of\ flower} =\frac{length\ of\ person\ shadow}{length\ of\ flower\ shadow}$

Find the exact area of a circle having the given circumference.

blagie [28]

Answer:

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

r - radius

The formula of a circumference of a circle:

$C=2\pi r$

We have:

$C=3\pi$

Substitute:

$2\pi r=3\pi$ <em>divide both sides by 2π</em>

$r=1.5$

Substitute:

$A=\pi(1.5)^2=2.25\pi$

Answer:

P(compact cars) = 4/25

Step-by-step explanation:

We know that there are 13 trucks, 8 vans, and 4 compact cars.

Let P denotes the probability of an event

Now we are asked to find the probability of compact cars

Number of favorable events = number of compact cars = 4

total number of outcomes = 13+8+4 = 25

hence, P(compact cars) = number of favorable events/total outcomes

=4/25
