Answer:
Adult required in the case of “a” 28 and in the case of “b” the adult requirement is 19.
Step-by-step explanation:
(a) The percentage of adult that support the change is 20 percent.
Now calculate the number of adult required.
Given p = 0.20
Use the below condition:
Since 35 adults are already there so required adults are 63 -35 = 28
(b) The percentage of adult that support the change is 25 percent.
Now calculate the number of adult required.
Given p = 0.25
Use the below condition:
Since 35 adults are already there so required adults are 54 -35 = 19
.
Answer:
10 people
Step-by-step explanation:
Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.
The amount spent on just tickets is therefore:
= 243.25 - 15.75
= $227.50.
If $227.50 was for tickets alone, the number of tickets they could buy is:
= Total amount left/ Price of tickets
= 227.50 / 22.75
= 10 people

Answer:
(1 + y)(x + 2y)
hope this is right
Step-by-step explanation:
A square side is twice of the radius
sq side: 4 x 2
sq side: 8
find the area of the square.
A = b x h
A = (8) x (8)
A = 64
<em>Area of square is 64</em>
----------------------------------------------------------------------------------------------------------------
Find the area of the circle
Area of circle:
A = πr²
A = π(4)²
A = 16π
A = 16(3.14)
A = 50.24
----------------------------------------------------------------------------------------------------------------
Divide the circle from the total
50.24/64
50.24/64 = 0.785
0.785 = 78.5/100 = 78.5%
----------------------------------------------------------------------------------------------------------------
Subtract the circle's percentage from 100% (the total)
100 - 78.5 = 21.5
21.5% is your chance of not hitting a point in the circle.
-----------------------------------------------------------------------------------------------------------------
21.5%, or (B), is your answer
-----------------------------------------------------------------------------------------------------------------

Answer:
In an arithmetic sequence, the difference between any two consecutive terms must always be the same number, which is known as the common difference.
So we just need to take different pairs of consecutive terms and see if their difference is always the same:
1) The differences are:
32 - 35 = -3
29 - 32 = -3
26 - 29 = -3
So yes, this is an arithmetic sequence and the common difference is -3
2) The differences are:
-23 - (-3) = -20
-43 - (-23) = -20
-63 - (-43) = -20
This is an arithmetic sequence, and the common difference is -20
3) The differences are:
-64 -(-34) = -30
-94 -(-64) = -30
-124 -(-94) = -30
This is an arithmetic sequence and the common difference is -30
4) The differences are:
-40 -(-30) = -10
-50 - (-40) = -10
-60 - (-50) = -10
This is an arithmetic sequence and the common difference is -10
5) The differences are:
-9 - (-7) = -2
-11 - (-9) = -2
-13 - (-11) = -2
This is an arithmetic sequence, and the common difference is -2
6) The differences are:
14 - 9 = 5
19 - 14 = 5
24 - 19 = 5
This is an arithmetic sequence, and the common difference is 5.
