You would have to find the proportionality of the two.  If his shadow is 3 feet long, and the tree's shadow is 9 that means it is proportioned by 3. So the height of the tree would be 15.

the perimeter of a rectangular painting is 304 CM. If the width of the paint is 63 cm what is the length​
s2008m [1.1K]

Answer:

The PERIMETER P is the distance around the rectangle.

Let's call the width of the rectangle W and the length of the rectangle L.

As you go around the edge there two equal lengths and two equal widths.

The formula for the perimeter of a rectangle is P=2*L+2*W.

P=2L%2B2W

Substitute 290 for P and 62 for the width.

290=2L%2B2%2862%29

Solve for L.

290=2L%2B2%2862%29

290=2L%2B124

290-124=2L

2L=166

L=83

The equation L=83 means that the length is 83 cm.

CHECK your work.

2(62)+2(83) = 124+166 = 290cm.

The length of the rectangle is 83cm.

Charra [1.4K]
 Gross Income of $54,300, Adjustments of $2460, 2 Exemptions of $16,400, and Deductions of $16,500?

Taxable amount = $54,300 - ( $2460 + $16,400 + $16,500 ) = 84,740.
I don't have the list of the tax bracket. The tax bracket of 2016 and 2017 are also different. Just get the tax bracket and multiply the taxable amount.
