Answer:
12 students.
Step-by-step explanation:
Since they served 36 pieces, and each student got 3 slices, then you would divide 36 by 3. 36 divided by 3 equals 12. So that means 12 students got served.
Answer:
= - 95n
Step-by-step explanation:
Note the difference between consecutive terms in the sequence is constant
- 190 - (- 95) = - 190 + 95 = - 95
- 285 - (- 190) = - 285 + 190 = - 95
- 380 - (- 285) = - 380 + 285 = - 95
This indicates that the terms are an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 95 and d = - 95, thus
= - 95 - 95(n - 1) = - 95 - 95n + 95 = - 95n
against wind the speed = x-y
distance traveled = 2460
2460/x-y= 6
6x-6y= 2460
x-y=410...........1
..
with wind speed = x+y
distance is same 2460
2460/x+y=5
5x+5y=2460
x+y=492............2
..
Add equation 1 & 2
x-y+x+y=410+492
2x=902
x= 451 mph speed of plane in still air.
..
Plug the value of x in equation 1
451-y=410
y=451-410
y=40 mph the speed of wind

Your feed back about the solution is very important in improvement.
First we need to convert pt into qt
1qt = 2pt
That means that 50 pt is:
50/2 = 25 qt
And now we convert qt to L
25/1.06 = 23,6 L
Answer is A) 23,6 liters
Applying the trigonometry ratios, the correct option is: B. none of these are correct.
<h3>What are the Trigonometry Ratios?</h3>
The trigonometry ratios are SOH CAH TOA, which are used for solving a right triangle.
Use the trigonometry ratio to find out which option is correct.
Cos Z = adj/hyp = 61/CZ, so option A is incorrect.
Sin Z = opp/hyp = 73/CZ, so option C is incorrect.
Tan Z = opp/adj = 73/61, so option D is incorrect.
Thus, the answer is: B. none of these are correct.
