Answer:
<h2>
12 m</h2>
Step-by-step explanation:
Given data
θ= 10°
Horizontal length is equivalent to the adjacent= 20 m
the height of the ramp is equivalent to the opposite=?
Applying SOH CAH TOA we have
using TOA
Tan θ= opp/adj
Tan 10= opp/20
opp= Tan(10)* 20
opp= 0.64836*20
opp= 12.96
Approximately the maximum height of the ramp is 12 m
d = 3 , a₁₂ = 40 and S = 7775
In an arithmetic sequence the nth term and sum to n terms are
<h3>• a
= a₁ + (n-1)d</h3><h3>• S
=
[2a + (n-1)d]</h3><h3>
where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ =
[(2×7) +(99×3)</h3><h3> = 25(14 + 297) = 25(311)= 7775</h3>
Answer:
Imagine if your friend is 3ft, and he is scaled down into the drawing. If he's scaled down into the drawing, he would be 1 inch in the drawing. If your cat were 1.5ft, it would be half of your friend, so in the drawing it would be 0.5 inch. Now the table is 9ft, how many 3ft is in 9ft? That's 3 times of 3ft, so 1 inch would be multiplied 3 times, = 3 inches. Or there's a shortcut way in the pic.
