Answer:
At a combined speed of 6 in/min, it takes us 24 mins to clean the wall
Step-by-step explanation:
Since the question did not provide the speed with which each student cleans, we can make assumptions. This is so that we can solve the question before us
Assuming student 1 cleans at a speed of 2 inches per minute, student 2 cleans at a speed of 2½ inches per minute & student 3 cleans at a speed of 1½ inches per minute.
Let's list the parameters we have:
Height of wall (h) = 12 ft, Speed (student 1) = 2 in/min, Speed (student 2) = 2½ in/min, Speed (student 3) = 1½ in/min
Speed of cleaning wall = Height of wall ÷ Time to clean wall
Time to clean wall (t) = Height of wall ÷ Speed of cleaning wall
since students 1, 2 and 3 are working together, we will add their speed together; v = (2 + 2½ + 1½) = 6 in/min
1 ft = 12 in
Time (t) = h ÷ v = (12 * 12) ÷ 6 = 144 ÷ 6
Time (t) = 24 mins
Answer:
y=1
Step-by-step explanation
the x is like a imaginary 1 so 4*x=4-3=1
Answer: 10, 15
Step-by-step explanation:
Given
Stephanie wants to raise at least $800
she plans on selling VIP tickets for $20 each and general admission for $40 each
suppose there are x and y tickets for VIP and general admission

solving above two inequality
Stephanie must sell 10 tickets for VIP and 15 tickets for general admission
Answer:
2000 times 3.5% is 70, so in one year you would have 2070 dollars. 3.5 divided by 3 is about 1.16 (the six repeats), so for the next 1/3 year you would do 2070 times 1.16 percent which is 30. So, then, 2070 plus 30 is 2100 dollars in the saving account.
Answer:
The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
Step-by-step explanation:
The statement describes an arithmetic progression, which is defined by following formula:
(1)
Where:
- First element of the sequence.
- Progression rate.
- Index of the n-th element of the sequence.
- n-th element of the series.
If we know that
,
and
, then the progression rate is:


The set of elements of the series are described by
.
Lastly, if we know that
, then the 300th term of the sequence is:


And the next three terms of the sequence are:
n = 5


n = 6


n = 7


The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
