Answer:
1303.45 cm
Step-by-step explanation:
The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.
Let x be the height of the tree. Setting the ratios equal, we get:
180/116 = x/840
Solve for x:
x = 840 * (180/116)
x ≈ 1303.45 cm
<h3><u>The value of x is equal to 8.</u></h3>
3(x + 1) = 19 + x
<em><u>Distributive property.</u></em>
3x + 3 = 19 + x
<em><u>Subtract x from both sides.</u></em>
2x + 3 = 19
<em><u>Subtract 3 from both sides.</u></em>
2x = 16
<em><u>Divide both sides by 2.</u></em>
x = 8
Answer:
800
Step-by-step explanation:
since 300 divided by 15 is 20.
20 x 40= 800
Answer:
A
Step-by-step explanation:
The Fibonacci sequence is the sum of the two terms before it. It looks like this:
1, 1, 2, 3, 5, 8, 13, 21, 34, ...
As you can see, 13 and 21 are indeed consecutive terms.
