10. In the drawing below, the dashed line segment represents the distance across a pond. What is the actual distance across the pond?
A. 27 in
Pond
B. 47 yds.
C. 10 in
1 Inch : 2 yards
D. 20 yds.
-8 in
6 in.
Scale

D. 20 yds

Step-by-step explanation:

✔️First, find the distance across across the pond on the drawing using Pythagorean Theorem:

Distance across = √(6² + 8²) = √100

Distance across on drawing = 10 in.

✔️Next, find the actual distance using the scale of 1 inch : 2 yards:

The scale implies that,

1 inch represents 2 yards

Therefore:

10 inches will represent = 10 × 2 = 20 yards

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
