(2)7.5 feet
Step-by-step explanation:
<u>Question 1</u>
The diagram is attached below.
Using Trigonometric ratio

The height of the house is 55.5 feet to the nearest tenth.
<u>Question 2</u>
In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.
Using Trigonometric ratio

The distance the bird must fly to be directly above the fish is 7.5 feet.
Answer:
Diameter of the smaller coin = 2.46 cm
Step-by-step explanation:
Circumference of a coin = 2πr
Circumference of coin A = 8.03 cm
Circumference of coin B = 8.03 cm - 0.33 cm
A.) what is the first step to find the diameter of the smaller coin?
Find the circumference of coin B
Circumference of coin B = 8.03 cm - 0.33 cm
= 7.7 cm
B.) Find the diameter of the smaller coin.
Circumference of a coin = 2πr
7.7 = 2 × 3.14 * r
7.7 = 6.28r
r = 7.7 / 6.28
r = 1.23 cm
Diameter = 2r
= 2 * 1.23 cm
= 2.46 cm
Diameter of the smaller coin = 2.46 cm
Answer:
Answer for #10:

Answer for #1:

Step-by-step explanation:
In order to solve a simultaneous equation using the substitution method you have to:
Use one of the equation and substitute it into the other equation, in this case equation <em>B</em><em> </em>was substituted into equation <em>A</em><em>.</em>
<em>
</em>
Therefore since x = 1 - y, equation A would be:

Answer:Its B
