An engineer charges £20 plus £p per hour to repair central heating boilers.
At one house a repair takes 3 hours and costs £71.
(a)
(b)
(c)
Determine the value of p.
Write down a formula for the cost, £C, of a repair that takes x hours.
A repair costs £96.50. How long does it take?
Answer:
the value of p is £3.67.
Step-by-step explanation:
(a) To determine the value of p, we need to use the information given in the problem to set up and solve a simple equation. The cost of the repair at one house was £71, and it took 3 hours, so the cost per hour was £71 / 3 = £<<71/3=23.67>>23.67 per hour. The engineer charges £20 plus £p per hour, so £23.67 per hour is equal to £20 + £p. Subtracting £20 from both sides gives us £p = £3.67. Therefore, the value of p is £3.67.
(b) The formula for the cost, £C, of a repair that takes x hours can be written as: £C = £20 + (£p * x). This formula states that the cost of the repair is equal to the fixed cost of £20, plus the cost per hour (£p) multiplied by the number of hours (x) that the repair takes.
(c) To determine how long a repair that costs £96.50 takes, we can use the formula from part (b) and solve for x. Substituting in the known values, we get: £96.50 = £20 + (£3.67 * x). Subtracting £20 from both sides gives us: £76.50 = (£3.67 * x). Dividing both sides by £3.67 gives us: x = 20.89 hours.
Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 60 . For one performance, 25 advance tickets and 20 same-day tickets were sold. The total amount paid for the tickets was $ 1325 . What was the price of each kind of ticket?
The price of each advanced tickets sold is; $35
The price of each same day tickets sold is; $25
How to solve a system of linear equations?Let x be the cost of each advanced tickets sold
Let y be the cost of each same day tickets sold
We are told that for one performance, 25 advance tickets and 20 same-day tickets were sold. Thus;
x + y = 60 ------(1)
The total amount paid for the tickets was $1325 and as such, we have;
20x + 25y = 1325 ------(2)
Make x the subject in eq 1 to get;
x = 60 - y
Put (45 - y) for x in eq 2 to get;
20(60 - y) + 25y = 1325
1200 - 20y + 25y = 1325
5y = 125
y = 125/5
y = $25
Thus;
x = 60 - 25

False: Two pounds of Apple do not cost more that $3.50
How to calculate the Unit rate of the cost per pound?
8 pounds of Apple costs $12
The unit rate is
8= 12
1= x
cross multiply both sides
8x= 12

2. If force F = î+2 ĵ+k and displacement S=3 î+ĵ+5k then work done by the force is a) 0 b) 10 unit c) 50 unit d) 8 unit
The work done by a force [tex]$\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2 \hat{\mathrm{j}}+3 \hat{\mathrm{k}}) \mathrm{N}$[/tex], to displace a body from position A to position B is 5j
What is force?A force in physics is an effect that has the power to alter an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe force. Being a vector quantity, a force has both magnitude and direction. The normal force operates in the opposite direction from how surfaces interact with one another. A force called friction prevents motion on surfaces. Other non-fundamental forces include the Coriolis force, the elastic force, tension, and frame-dependent forces like centrifugal force.Now basically here we, are talking about the work done by a body in the form of displacement.
This displacement is done due to the force that acted upon the body.
To calculate the work done we use the formula as,
W = F.ds
where F is the force acted on the body and the 'ds' is the displacement vector or the factor,
thus we calculate 'ds' as
AB vector = r2 - r1
AB = (2i + 2j +3k ) - ( i+3j+k)
so we get as,
AB = i -j +2k
now substituting in the formula we get as
W = (i + 2j + 3k ) .(i - j +2k)
W = 1 -2 +6
W = 5 joules
Work done = 5 J
The complete question is,
The work done by a force [tex]$\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2 \hat{\mathrm{j}}+3 \hat{\mathrm{k}}) \mathrm{N}$[/tex], to displace a body from position A to position B is : [The position vector of A is [tex]$\overrightarrow{r_1}=(\hat{i}+3 \hat{\jmath}+\hat{k}) \mathrm{m}$[/tex] and the position vector of B is [tex]$\left.\overrightarrow{r_2}=(2 \hat{i}+2 \hat{j}+3 \hat{\mathbf{k}}) \mathrm{m}\right]$[/tex]

Write an inequality to represent the graph.
The inequality which correctly represents the graph as represented in the task content is; y ≤ ( -1/4 ) x + 2.
Which inequality correctly represents the given graph?First, to determine the inequality which represents the graph given, it is important to determine the equation of the border line as follows;
Since the slope formula is; m = (y₂ - y₁) / (x₂ - x₁).
Hence, given points; ( 0, 2 ) and ( 4, 1 ).
Slope, m = ( 1 - 2 ) / ( 4 - 0 )
m = -1 / 4 and y-intercept = 2.
Therefore, it follows from the slope-intercept form equation; y = mx + c that the equation of the boundary line in discuss is;
y = ( -1/4 ) x + 2.
On this note, since the region shaded on the graph is the region below the boundary line and the boundary line is a solid line;
It follows that the required inequality which the graph represents is; y ≤ ( -1/4 ) x + 2.

11 buses can carry 495 passengers how many peple can fit in 8 buses
Answer:
Step-by-step explanation:
360 people can fit in 8 buses.
First we need to find how many people fit in 1 bus, so we can divide 495, the total number of people, by 11, the number of buses.
495/11=45
Now we know 45 people can go on 1 bus, and we have 8 of them, so we multiply these 2 numbers.
45*8=360
360 people.
Answer:
8 buses can carry 360 passengers
If this help please set brainliest.
Step-by-step explanation:
To find out how many people can fit in 8 buses, you need to multiply the number of people that can fit in one bus by the number of buses. Since 11 buses can carry 495 passengers and each bus can carry the same number of passengers, one bus can carry 495/11=45 45 passengers.
Therefore, 8 buses can carry 360 passengers.
When rolling a certain unfair six-sided die with faces numbered 1, 2, 3, 4, 5, and 6, the probability of obtaining face F is greater than 1/6, the probability of obtaining the face opposite is less than 1/6, the probability of obtaining any one of the other four faces is 1/6, and the sum of the numbers on opposite faces is 7. When two such dice are rolled, the probability of obtaining a sum of 7 is 47/288. given that the probability of obtaining face is where and are relatively prime positive integers, find m+n?
The sum of the two numbers on the opposite faces of the die is 7. The probability of rolling a sum of 7 when two dice are rolled is 47/288. Since the probability of obtaining an individual face is , m+n must be 11.
Let m and n be the numbers on opposite faces of the die.
Since the sum of the numbers on opposite faces is 7,
m+n = 7.
Since the probability of obtaining face F is greater than 1/6, we can write .
Since the probability of obtaining the face opposite is less than 1/6, we can write .
Since the probability of obtaining any one of the other four faces is 1/6, we can write .
