<h2><u><em>0.04(30h) is the part.</em></u></h2><h2>please mark brainliest :)</h2>

0.04(30h) is the part. Because 0.04 represents 4%, we know that it should be the tax rate. 30h represents the cost for every hour, so we know that that's not the correct answer.

Divide 33 photos into 2 groups so the ratio is 4 to 7.

kvv77 [185]

So you want two groups that are in a ratio of 4 to 7
so 33=4x+7x
so 33=11x
so x=3

that means the groups are 4*3= 12 and 7*3=21

The area of a rectangle is 229.2 m2. If the length is 15 m, what is the perimeter of the rectangle

igor_vitrenko [27]

Answer:

$\large\boxed{P=60.56\ m}$

Step-by-step explanation:

The formula of an area of a rectangle:

$A=lw$

l - length

w - width

We have

$A=229.2\ m^2\\\l=15\ m$

Substitute:

$15w=229.2$ <em>divide both sides by 15</em>

$w=15.28\ m$

The formula of a perimeter of a rectangle:

$P=2(l+w)$

Substitute:

$P=2(15+15.28)=2(30.28)=60.56\ m$
