Height of triangle (h) = 2.5 + 4 = 6. 5 cm
Base of triangle (b) = 3 + 3 = 6 cm
Radius of circle (r) = 4 cm
Required probability = Area of triangle/Area of circle

Part I. A New Bike and Skateboard Problem
Uncle Eddie asked McKenna and Lara to order 108 new wheels for the 42
skateboards and bicycles in his repair shop. How many bicycles and how
many skateboards are in Uncle Eddie's shop?
Answer:
Number of bicycles = 30
Number of skateboards = 12
Step-by-step explanation:
Let the number of bicycles = x
Let number of skateboards = y
It is given that there are total bicycles and skateboards = 42
∴ x + y = 42 ........(1)
Now a bicycle has two tires and a skateboard has four tires, this gives an equation :
2x + 4y = 108 .......(2) (Since uncle Eddie asks to order 108 tires)
Therefore, solving equation (1) and (2), we get
2(x+y=42)
2x+4y=108
2x+2y = 84
- (2x+4y = 108)
- 4 y = - 24
or 4 y = 24
or y = 12
Now substituting the value of y in equation (1),
x + 12 = 42
x = 42 -12
x = 30
So number of bicycles = x =30
And number of skateboards = y = 12

A buoy is floating in the sea and can be seen from the top of a vertical cliff. A boat is travelling from the base
of the cliff directly towards the buoy. The top of the cliff is 142 m above sea level. The angle of depression
from the top of the cliff to the buoy is 40 degrees.
Answer:
169.23m
Step-by-step explanation:.
Let's calculate the base of the cliff. Using SOH CAH TOA identity
Height (opposite) = 142n
Angle of depression = 40°
Required
Base of the cliff
Tan theta = opposite/adjacent
Tan 40 = 142/x
x = 142/tan40
x = 142/0.8391
x = 169.23m
Hence the base of the cliff is 169.23m long

2. On the Internet, you find an Latin quiz with 10 matching vocabulary questions. Your 3 year old niece randomly matches the
words with the definitions. What is the probability that she makes 100 on the quiz?
Does the order matter? Yes -
This is a permutation
Will all of the words be matched? Yes -
Can we use factorials? Yes -
How many different ways can the answer key be arranged?
P(all correct)
(Enter your answer as a reduced fraction using/ for the fraction bar.)
Answer:
Assume that there is a Latin quiz with 10 matching vocabulary questions, and your niece try to match them randomly. Then, the probability that she gets the first item right is
1
10
since there is only one correct answer for this item out of 10 options. Now, the probability that she gets the second item right is
1
9
since there is only one correct option and there is only 9 options left to choose from. So, in a similar fashion, the probability that she will get the third item correct is
1
8
, the fourth item correct is
1
7
and so on. Therefore, the probability that she will match them all correctly (getting a 100 on the quiz) is equal to

Your total at a
restaurant is $50. If you
want to tip the server
15%, what is your
total?
Answer:
tip: $7.50
total: $57.50
Step-by-step explanation:
you change the 15% into a decimal by moving the the decimal point 2 spots to the left so now you have .15
next do .15 * 50 to get 7.5, which is the tip
now to find the total, add 7.5 + 50 to get 57.5
Answer:
your total cost would be $57:50

A blimp is flying directly above a football field. The angle of depression to the base of one goal post is 40°. The angle of depression to the base of the other goal post is 72°. If the goal posts are 360ft apart, how high is the blimp flying? Round to the nearest tenth of a foot.
Answer:
. A blimp is flying directly above a football field. The angle of depression. 555.OF+ to the base of one goal post is 40. The angle of depression to the base of the other goal post is 72". If the goal posts are 360 feet apart. 7. how high is the blimp flying? Round to the nearest tenth of a foot. : a Sih C 8 360 5in (68) 333.8 36 0F 7. The bearing from a lighthouse to Ship A is S71 E. The bearing from the lighthouse to Ship B is S 39° E. If Ship A is 15 kilometers from the lighthouse and Ship B is 96 kilometers from the lighthouse, find the distance between the ships. Find the areg of each triangle. Round answers to the nearest tenth. B. 84.0 8. 2. 11m ((uSin 64) 15.q ft 64 10.
The blimp flying is "237 m" high.
Angle of depressionAccording to the question,
In ΔABC,
∠XCA = ∠CAB = 72°
∠YCB = ∠CBA = 40°
Now,
→ ∠A + ∠B + ∠C = 180°
By putting the values,
72° + 40° + ∠C = 180°
112° + ∠C = 180°
∠C = 180° - 112°
= 68°
By applying Sin Rule,
→ [tex]\frac{AB}{Sin \ 68^{\circ}} = \frac{AC}{Sin \ 40^{\circ}}[/tex]
AC = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex]
We know that,
Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° ...(Equation 1)
Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × h ...(Equation 2)
From "Equation 1 and 2",
→ [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° = [tex]\frac{1}{2}[/tex] × AB × h
h = AC × Sin 72°
By substituting value of "AC",
= [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex] × Sin 72°
= 237.36 or, 273 m
Thus the answer above is correct.

If the length of a side of a square is increased from 4 to 8, which of the following statements is true?
A.) Both area and perimeter are doubled.
B.) Both the area and perimeter are quadrupled.
C.) The perimeter is doubled and the area is quadrupled.
D.) The perimeter is quadrupled and the area is doubled.
Answer:
C.) The perimeter is doubled and the area is quadrupled.
Step-by-step explanation:
Original square: side = 4
Area = side^2 = 4^2 = 16 square units
Perimeter = 4 * side = 4 * 4 = 16 units
Larger square: side = 8
Area = side^2 = 8^2 = 64 square units
Perimeter = 4 * side = 4 * 8 = 32 units
Comparison of areas:
(larger square area)/(original square area) = 64/16 = 4
Comparison of perimeters:
(larger square perimeter)/(original square perimeter) = 32/16 = 2
Answer:
C.) The perimeter is doubled and the area is quadrupled.

Only 3% of turtle hatchlings will live to become breeding adults. How many turtles must have been born if the current number of breeding adults is 1,200?
Answer:
116400 I believe not 100% sure tho
The total number of turtles born is 40,000.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, only 3% of turtle hatchlings will live to become breeding adults.
The current number of breeding adults is 1,200
Let the total number of turtles born be t.
Now, 3% of t=1200
3/100 ×t=1200
3t=120000
t=40000
Therefore, the total number of turtles born is 40,000.

what conclusions can you give why some students decided not to go to school?
Step-by-step explanation:
There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.
There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.
It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.
