Paul, Colin and Brian are waiters. One night the restaurant earns tips totalling £78.40. They share the tips in the ratio 1:3:5. How much more does Colin get over Paul?
Answer:
Share of Paul = 2/8*78.40=19.6
Share of Colin = 5/8*78.40=49
And
Share of Brian =1/8*78.40=9.8
Step-by-step explanation:
They share the tips in the ratio 2:5:1.
It means , the total share is 8 ,
that 2 out of 8 is the share of Paul
5 out of 8 is the share of Colin
And 1 out of 8 is the share of Brain
Now total tip = 78.40
Share of Paul = 2/8*78.40=19.6
Share of Colin = 5/8*78.40=49
And
Share of Brian =1/8*78.40=9.8

A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 2780 seats. The students left 15% of the seats in the theater vacant. How many 6th graders went on the trip?
Answer:
1242 6th graders went on the trip.
Step-by-step explanation:
From the information given, you know that the theater has 2760 seats and that the students filled 45% of the seats, so to find the quantity of 6th graders that went on the trip, you have to calculate 45% of 2760:
2760*45%=1242
According to this, the answer is that 1242 6th graders went on the trip.

What is the value of n in the equation
1/2(n+2)+4=3n-5
Answer:
n = 4
Step-by-step explanation:
1/2(n + 2) + 4 = 3n - 5
1/2n + 5 = 3n - 5
- 5 | - 5
1/2n = 3n - 10
- 3n | - 3n
-5/2n = -10
* 2 | * 2
-5n = -20

Justin charges $21 per linear foot to install a wood fence. It costs him $19 per line foot plus $4000 to purchase materials and hire installers each month. How many linear feet of fencing would he need to install each month to break even?
Answer:
21x=19x+4000
minus 19x
then divide by 2
×=2000
Justin needs to install 2000 linear feet of fencing each month to break even.
What is Break Even Point?The Break Even Point, or the inflection point at which a corporation starts to make a profit, is the amount of output required for a company's revenue to equal its total costs.
Let x be the number of linear feet of fencing Justin installs each month. Then his costs would be 19x + 4000 and his revenue would be 21x.
To determine when he's breaking even we need to make the equation of his costs equal to the revenue.
19x + 4000 = 21x
We can subtract 19x from both sides of the equation to get:
4000 = 2x
Then we can divide both sides by 2 to get:
x = 2000
Thus, he needs to install 2000 linear feet of fencing each month to break even.

A flagpole is 12 feet tall. If the flagpole casts a 50-foot shadow, then what is the angle of elevation to the sun?
А
76.5
B
51.4
4.2
D
13.5
Answer:
[tex]\theta=13.5^{\circ}[/tex]
Step-by-step explanation:
Given that,
The height of a flagpole, h = 12 feet
the height of the shadow, b = 50 feet
We need to find the angle of elevation of the sun. Let it is be θ. Using trigonometry to find it.
[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{12}{50}\\\\\theta=13.49^{\circ}\\\\or\\\theta=13.5^{\circ}[/tex]
So, the angle of elevation to the sun is equal to [tex]13.5^{\circ}[/tex].

The Celluloid Cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. A child ticket cost
$7 and an adult ticket is cost $10. If the cinema sold $1470 worth of tickets, which system of equations could be used to determine how
many adult tickets, a, and how many child tickets, c, were sold?
Answer:
a + c = 150
7.75a + 10.25b = 1470
Step-by-step explanation:
Let a represent the number of adult tickets that were sold.
Let c represent the number of child tickets that were sold.
The celluloid cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. This means that
a + c = 150 - - - - - - - - - - - - - -1
A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, it means that
7.75a + 10.25b = 1470 - - - - - - - - -2
