Answer:
3
Step-by-step explanation:
The coach divides her 9-player squad into 3-player groups. This means that she has 9 players and she wants to share them into 3s.
The number sets of three groups she will have can be obtained by dividing the total number of her players by the 3. That is:
9 / 3 = 3 sets
Therefore, she will have 3 sets of 3-player groups.
For the 2017-2018 school year, the average costs for one year of education is:
Tuition/Fees: $4,391
Living Costs: $10,406
Books/Supplies: $1,724
Transportation: $2,313
Other Expenses: $3,025
With the given 7% inflation rate, the average cost will increase for the next session (2018-2019).
Hence, for year 2017-2018 the total expense will be sum of all the given costs.
= $4,391 + $10,406 + $1,724 + $2,313 + $3,025
= $21,859
Answer:
64°
Step-by-step explanation:
Check the attachment for the diagram. Since the triangle has one of its angle as 90°, it is a right angled triangle.
Using the SOH CAH TOA trigonometry ratios:
Since ∠P is opposite to side QR,
QR = opposite side = 8ft
RP = adjacent side = 3.9ft
According to TOA
Tan∠P = Opposite/Adjacent = QR/RP
Tan∠P = 8/3.9
Tan∠P = 2.05
∠P = arctan 2.051
∠P = 64°
A.
h = 14 ft · sin 30° = 14 ft · 0.5 = 7 ft.
b.
From the bottom of the height to the bottom of the slide:
y² = 14² - 7² = 196 - 49 = 147
y = √147 = 12.12 ft
15 ft - 12.12 ft = 2.88 ft ( from the bottom of the stairs to the bottom of the height )
tan x = 7 / 2.88 = 2.43
∠x = tan^(-1) 2.43
∠x = 67.63° ≈ 68°.
