age 16 and over: £32.70
under 16: £17.90
143 people pay and 38 of these people are under 16.
How much ticket money is collected?
Answer:
£4113.70
Step-by-step explanation:
Given that:
143 people pay ; out of which 38 are under 16 ;
Hence ; 143 - 38 = 105 are over 16
Under 16 = £17.90
£17.90 * 38 = £680.20
16 and Over : = £32.70
£32.70 * 105 = £3433.50
£(680.20 + 3433.50) = £4113.70
Raj studied for4/7of an hour,while ram studied for 5/8 of an hour.who studied for longer time
Answer:
Ram studied for longer time
Step-by-step explanation:
An hour = 60 minutes
Raj studied for 4/7 of an hour
= 4/7 of 60 minutes
= 4/7 × 60
= (4×60)/7
= 240/7
= 24.29 minutes
ram studied for 5/8 of an hour
= 5/8 of 60 minutes
= 5/8 × 60
= (5×60)/8
= 300/8
= 37.5 minutes
who studied for longer time?
Ram - Raj
= 37.5 - 24.29
= 13.21 minutes
Ram studied for longer time
Ram studied 13.21 minutes longer than Raj

Suppose f(x) =log(x-3) and a g(x)=x+4.
Find the domain of. (fog)(x)
Answer:
x > -1
Step-by-step explanation:
p = (f o g)(x) = log ((x+4)-3)
p = log (x+1)
so that p has a value,
the value of x + 1 mus be greater than 0
x + 1 > 0
x > -1
so the domain is x > -1
Domain = {x | x > -1, x must real number}
Rachel’s earrings are in the shape of a triangle. The height of the earrings is 1 1/2 inches and the base is 3/5 inches. What is the area of both of Rachel’s earrings?
Formula: A=1/2bh
Formula: A=0.5 x b x h
Answer:
9/10
Step-by-step explanation:
First, 1 1/2 as a improper fraction is 3/2
Second, 3/2 x 3/5 = 9/10
Third, you need to do 9/10 x 2 since there are two earings which equals 18/10.
Fourth, 18/10 divided by 2 = 9/10 which means that the area of both earrings is 9/10

Can anyone help me out on this not too sure on this
Answer:
y = 0.1x - 4
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-3, 7)
Points on the y-axis (y1, y2) = (-7, -6)
First of all, we would find the slope;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
Slope = (-6 - (-7))/(7 - (-3))
Slope = (-6 + 7)/(7 + 3)
Slope = 1/10
Slope = 0.1
Next, we would write the equation using the formula;
y - y1 = m(x - x1)
y - (-7) = 0.1(x - (-3))
y + 7 = 0.1(x + 3)
y + 7 = 0.1x + 3
y = 0.1x + 3 - 7
y = 0.1x - 4

Polly surveyed 850 teenagers to find out their favorite type of music. She found that 32% of the teenagers surveyed like hard rock.
Part A: How many teenagers surveyed like hard rock? Show your work. (4 points)
Part B: In another survey, Damian found that 75% of the total number of teenagers surveyed like pop music. If 150 teenagers like pop music, what is the total number of teenagers that Damian surveyed? Show your work. (4 points)
Part C: Give an example of a situation in which a percentage is greater than 100%. (2 points)
Answer:
Step-by-step explanation:
A) There are 850 total teens and 32% like rock.
32% of 850 = 0.32*850 = 272 teens like rock
B) 75% of teens = 150 teens. Make total teens = x. 75%x = 150
0.75x = 150
x = 200 teens like pop

Which function has a remainder of 18 when divided by (x-2)?
The function that has a remainder of 18 when divided by ( x-2 ) is
f ( x ) = 2x⁴ + 4x² - 10x - 10
What is a polynomial function?
A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.
Given data ,
The divisor = ( x - 2 )
The remainder = 18
The function will be f( x ) = 2x⁴ + 4x² - 10x - 10
Step 1 :
Divide f ( x ) by ( x-2 ) = [tex]\frac{2x^4+4x^2-10x-10}{x-2}[/tex]
=
[tex]2x^3+\frac{4x^3+4x^2-10x-10}{x-2}[/tex]
Step 2 :
Divide [tex]\frac{4x^3+4x^2-10x-10}{x-2}[/tex]
=
[tex]2x^3+4x^2+\frac{12x^2-10x-10}{x-2}[/tex]
Step 3 :
Divide [tex]\frac{12x^2-10x-10}{x-2}[/tex]
=
[tex]2x^3+4x^2+12x+\frac{14x-10}{x-2}[/tex]
Step 4 :
Divide [tex]\frac{14x-10}{x-2}[/tex]
=
[tex]2x^3+4x^2+12x+14+\frac{18}{x-2}[/tex]
The remainder is 18 at the end of step 4
Hence , the function that has a remainder of 18 when divided by ( x-2 ) is
f ( x ) = 2x⁴ + 4x² - 10x - 10

Leeson can proofread a newspaper copy in 4 hours. If Ryan proofreads the same newspaper copy, it takes 3 hours. How
long would it take if they worked together?
Answer:
1 hour
Step-by-step explanation:
It would take that long because they work together, at 4 hours Ryan's 3 are subtracted and the result would be 1 hour. This is because while one of us makes the errors in the first or second paragraph, the other is checking the next and thus they finish faster.
If they worked together they can finish the given task in [tex]\frac{7}{12}[/tex] hours.
Given that, Leeson can proofread a newspaper copy in 4 hours. If Ryan proofreads the same newspaper copy, it takes 3 hours.
We need to find how long would it take if they worked together.
What is the formula to find the work done?Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.
Now, the work done by Leeson [tex]=\frac{1}{4}[/tex] and the work done by Ryan [tex]=\frac{1}{3}[/tex]
So, work done by both together [tex]=\frac{1}{4}+\frac{1}{3}=\frac{3+4}{12}=\frac{7}{12}[/tex] hours.
Therefore, if they worked together they can finish the given task in [tex]\frac{7}{12}[/tex] hours.

As a ship approaches the dock, it forms a 70 angle between the dock and the lighthouse. At the lighthouse, an 80 angle is formed between the dock and the ship. How far is the ship from the dock?
Answer:
The distance from the ship to the dock is approximately 5.24 miles
Step-by-step explanation:
From the parameters given in the question, we have;
The angle formed between the dock and the lighthouse = 70°
The angle formed between the dock and the lighthouse at the ship = 80°
The distance between dock and the lighthouse = 5 miles (From a similar question online)
By sine rule, we have;
[tex]\dfrac{a}{sin(A)} = \dfrac{b}{sin(B)} = \dfrac{c}{sin(C)}[/tex]
Therefore, we have;
[tex]\dfrac{5}{sin(70^{\circ})} = \dfrac{The \ distance \ from \ the \ ship \ to \ the \ dock}{sin(80^{\circ})}[/tex]
[tex]\therefore The \ distance \ from \ the \ ship \ to \ the \ dock = sin(80^{\circ}) \times \dfrac{5}{sin(70^{\circ})}[/tex]
[tex]sin(80^{\circ}) \times \dfrac{5}{sin(70^{\circ})} \approx 5.24 \ mi[/tex]
Therefore;
The distance from the ship to the dock ≈ 5.24 miles
