Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>
![\frac{x}{y} = \frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7By%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D%20)
<span>The new ratio is obtained like this:
</span>
![\frac{x+20}{y-20} = \frac{3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B20%7D%7By-20%7D%20%3D%20%5Cfrac%7B3%7D%7B1%7D%20)
.
From the above equation we get
![x= (y-20)\frac{3}{1} -20](https://tex.z-dn.net/?f=%20x%3D%20%28y-20%29%5Cfrac%7B3%7D%7B1%7D%20-20)
.
then
![\frac{ (y-20)\frac{3}{1} -20}{y} = \frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%28y-20%29%5Cfrac%7B3%7D%7B1%7D%20-20%7D%7By%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D%20)
Solving the above equation for y we get:
![y=160](https://tex.z-dn.net/?f=y%3D160)
So
So the first tree is (400-160=240) more taller than cherry tree.
Complementary angles are angles whose sum is 90 degrees.
90 - 67 = 23
23 degrees is the measure of its complementary angle.
Hey there, the answer is C.
After multiplying, you will get .37278. However, it's asking you to consider the significant figure of 3 so you'll have to round it to .373. C has that only option
Answer:
$6.03
Step-by-step explanation:
Let's begin by listing out the given variables:
height (h) = 12 cm, diameter (d) = 8 cm, r = d ÷ 2 ⇒ r = 4 cm, cost of coconut oil (c) = $0.01 /cm³
The formula of cylinder is given by:
V = πr²h = π * 4² * 12 = <u>603.1858 cm³</u>
cost of filling the tin can with coconut oil = cost of coconut oil * Volume of cylinder
Cost = c * V = 0.01 * 603.1858
Cost = $<u>6.03</u>
