Allister, who is 5 feet tall, is standing three feet from a mirror lying on the ground. When he looks into the mirror, he can just see the top of a tree that is 24 feet away from the mirror. Make a sketch of this situation, and use it to calculate the height of the tree
Answers
Answer:
40 feets
Step-by-step explanation:
Given that :
Observer's height = 5 feets
Observer's distance from the mirror = 3 feets
Distance of tree away from the mirror = 24 feets
To obtain the height of tree:
Observer's distance (Od) / tree distance (Td) = Observer's height(Oh) / tree height (Th)
Od / Td = Oh / Th
3 / 24 = 5 / Th
3 * Th = 24 * 5
Th = 120 / 3
Th = 40 feets
Hence, the height of tree is 40 feets

Answers
Answer:
x = 8, y = 4
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , thus
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
x × [tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
x = 8
--------------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° = [tex]\sqrt{3}[/tex] , thus
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4\sqrt{3} }{y}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by y )
4[tex]\sqrt{3}[/tex] = y × [tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
y = 4

Katie feeds her cat, Elmer, 2/3 of a cup of food each day. She buys a bag of cat food that contains 18 cups of dry
food. How many days will that bag of cat food last?
Answers
Answer:
27
Step-by-step explanation:
Set up a proportion.
1 day / (2/3 cup) = x/ 18 cups Cross Multiply
1 day * 18 cups = 2/3 cup * x Multiply both sides by 3
1 day * 18 cups * 3 = 2x
54 day cups = 2x cups Divide by 2
54 day cups/2 cups = x
27 days (The cups cancel)
Answer:
27 days it will last

A fishing boat has snagged a fish and want to know the depth of the fish. If the there is
18 meters of fishing line out and the angle of depression is 24º, how deep is the fish?
Round the nearest tenth of a meter.
Answers
7.3 meters
Step-by-step explanation:
hypotenuse = 18
angle depression = 24 degrees
missing side = opposite, x
since this has opposite and the hypotenuse were going to use sin
sin(24 degrees) = .40673664307
multiply .40673664307 by the length (18) = 7.32125957526 rounded down =7.3 meters
The depth of the fish is 7.3 meters if the fishing boat has snagged a fish and wants to know the depth of the fish. If there is 18 meters of fishing line out and the angle of depression is 24º.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
A fishing boat has snagged a fish and wants to know the depth of the fish. If there are 18 meters of fishing line out and the angle of depression is 24º
We can draw a right-angle triangle:
From the right-angle triangle:
Let x be the depth of the fish.
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying sin ratio:
sin24 = x/18
x = 18sin24
x = 7.32 meters ≈ 7.3 meters
Thus, the depth of the fish is 7.3 meters if the fishing boat has snagged a fish and wants to know the depth of the fish. If there is 18 meters of fishing line out and the angle of depression is 24º.

E.
There were 22,157 tacos sold in May and June combined.
Part B
How many more tacos were sold in July than in May and August combined? Enter your answer in the box.
Answers
Answer:
Step-by-step explanation:
A: Correct
June + August > July
12,832 + 8,465 > 20,005
21,297 > 20,005
B: Wrong
July = June + 8,173
20,005 = 12,832 + 8,173
20,005 ≠ 21005
C: Correct
July + August > May + June
20,005 + 8,465 > 9,325 + 12,832
28470 > 22157
D: Wrong
9,325 +12,832 +20,005 + 8,465 = 50627
E: Correct
May + June = 22,157
9,325 + 12,832 = 22,157
22,157 = 22,157
Part B: 2215
July - May + August = ?
20,005 - 9,325 + 8,465 = ?
20,005 - 17790 = 2215
