Answer:
Lucy sews dresses in 1 hour.
Step-by-step explanation:
Given:
Lucy sews of a dress in
hour.
She sews at constant rate.
We need to find the number of dresses she makes in 1 hour.
In hour =
dress
So in 1 hour = Number of dresses in 1 hour
By using Unitary method we get;
Number of dresses in 1 hour=
Hence Lucy sews dresses in 1 hour.
<h3>Answer: 24 feet (Choice D)</h3>
=============================================
Explanation:
Refer to the diagram below. The goal is to find x, which is the horizontal distance from the base of the tree to the swing set.
Focus on triangle BCD.
The angle B is roughly 30.26 degrees, and this is the angle of depression. This is the amount of degrees Emir must look down (when starting at the horizontal) to spot the swing set.
We know that he's 14 ft off the ground, which explains why AB = CD = 14.
The goal is to find BC = AD = x.
---------------------------
Again, keep your focus on triangle BCD.
We'll use the tangent ratio to say
tan(angle) = opposite/adjacent
tan(B) = CD/BC
tan(30.26) = 14/x
x*tan(30.26) = 14
x = 14/tan(30.26)
x = 23.9965714046732
That value is approximate. Make sure your calculator is in degree mode.
That value rounds to 24 feet when rounding to the nearest whole foot.
