Olly drove 56 km from Liverpool to Manchester.
He then drove 61 km from Manchester to Sheffield.
Olly's average speed from Liverpool to Manchester was 70 km/h.
Olly took 75 minutes to drive from Manchester to Sheffield.
Work out Olly's average speed for his total drive from Liverpool to Sheffield.
Input note: give your answer correct to 1 decimal place.
give right answer brainiest! please help!
Answer: 57.1 km/ h
Step-by-step explanation:
First find the amount of time it took for Olly to drive from Liverpool to Manchester.
Time = Distance / Speed
= 56 / 70
= 0.8 hours
It took 75 minutes to drive from Manchester to Sheffield. In hours that it:
= 75 / 60 minutes
= 1.25 hours
Total time taken to travel from Liverpool to Sheffield is therefore:
= 0.8 + 1.25
= 2.05 hours
Distance travelled from Liverpool to Sheffield:
= Distance from Liverpool to Manchester + Distance from Manchester to Sheffield
= 56 + 61
= 117 km
Average speed for the whole journey is therefore:
= Distance / Time
= 117 / 2.05
= 57.1 km/ h

Answer:
In the first case x and y be 49 and 47 respectively
In the second case x and y be 41 and 37 respectively
Step-by-step explanation:
Let us assume the two number be x and y
In the first case
Now
x + y = 96
x - y = 2
2x = 98
x = 49
y = 49 - 2 = 47
So x and y be 49 and 47 respectively
In the second case
x + y = 78
x - y = 4
2x = 82
x = 41
y = 78 - 41 = 37
So x and y be 41 and 37 respectively

sides are = so angles are also = !
Answer:
50°
Step-by-step explanation: because this is an isosceles triangle, both of the base angles are equal to one another, making x=50. Hope this helps :)
How many radians is 252°?
Give the exact answer in simplest form
Radian is a more advanced degrees measurement that is easier to use in trigonometry physics etc.
A full circle 360 degrees is 2pi radian.
We just need to find the ratio of 252 degrees to 360 degrees and multiply that by 2pi.
252/360*2pi(rad)
=126/180*2pi(rad)
=63/90*2pi(rad)
=21/30*2pi(rad)
=7/10*2pi(rad)
=7/5*pi (Radian)

Solve the system by substitution. Check your solution. A minus 1.2 b = negative 3. 0.2 b + 0.6 a = 12 a. (15, 15) c. (13, 12) b. (10, 12) d. (7, 9)
Answer:
The answer to the question is -1.32
Step-by-step explanation:
The first step will be to write out the equation that we are working with:
This equation is
[tex]0.2b + 0.6a = 12[/tex]
The next step is to write out the values of the figures that we are substituting:
[tex]a = -1.2 b=-3[/tex]
Substitution in mathematics can best be understood as "something being used in place of another thing". This means that wherever the first variable appears in an equation, the substituting values will replace it and multiply the number it is attached to.
In this case, we will replace the 'b' and the 'a' with the - 1.2 and - 3 respectively.
[tex]0.2(-3) + 0.6(-1.2) = -1.32[/tex]

Describe the square roots of numbers using 2 sentences.
Write one sentence describing the square roots of numbers such as √0.6, which is less than 1.
Write another sentence describing the square roots of numbers such as StartRoot 1.6 EndRoot, which is greater than 1.
Answer:
Square roots of numbers less than 1 are between 0 and 1, while square roots of numbers greater than 1 are greater than 1. For numbers between 0 and 1, the square root is greater than the number; for numbers larger than 1, the square root is less than the number.
Step-by-step explanation:
The square root of a number less than one is a value that is less than one. The value of the square root of a number greater than one must also be greater than one.
What is square root?The square root of a number is the value obtained when the number is raised to the power of 1/2. The symbol of square root in mathematics is √.
If a number is less that 1. its square root must also be less than 1. Similarly, for the numbers that are greater than one, the square root of the number must also be greater than one.

Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why?
(6, 20), because the point does not lie on any axis
(6, 20), because both lines pass through this point
(3, 11), because one of the lines passes through this point
(3, 11), because the point lies between the two axes
Answer:
(6,20) because both lines pass through this point
Step-by-step explanation:
To solve this you can use the substitution method.
Since both of them are equal to y, substitute one of the equations for y, that way you have x+14 = 3x+2. From here you continue to simplify.
Eliminate x from either side of the equation. For example, subtract x from the side that says "x+14". (Make sure you are also subtracting it from the other side of the equal sign as well.
Once you do this you should now have 14 = 2x+2
In order continue, you now have to get x by itself. So now subtract 2 from both sides of the equation. After doing this, you should have 12 = 2x
You then simplify x by dividing both sides by 2. This will get you x = 6
Now that you have the x-value, substitute that into either of the two equations (it is recommended you substitute it into both equations to make sure you have the correct x-value). For example: If I substitute x into Line C's equation, I will now have y = 6 + 14.
6 + 14 is 20, therefore you're y-value is y = 20

A taxi company charges passengers $2.00 for a ride, no matter how long the ride is, and an additional $0.20 for each mile traveled. The rule c = 0.20m + 2.00 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?
A. $2.20; $2.54
B. $0.20; $0.54
C. $2.00; $2.20
D. $0.20; $5.60
Answer:
A. $2.20; $2.54
Step-by-step explanation:
Answer:
A. $2.20; $2.54
Step-by-step explanation:
It should give you 2.54.
First, you have to multiply 2.7 miles times .20 miles. It gives you .54, which you are supposed to add 2.00 to it for every ride.
c =0.20m + 2.00
Where c is the cost and m = number of miles,
For a 2.7 mile ride, m = 2.7
c = 0.20m + 2.00, m = 2.7
c = 0.20*2.7 + 2
c = 0.54 + 2
c = 2.54
Charge for the ride = $2.54

On 9th May, 2009, there were 3440 people in the world with swine flu. Of these people, 1639 were in the USA. The 3440 people who had swine flu on 9th May was an increase of 37.6% on the number of people who had swine flu on 8th May. Calculate the number of people who had swine flu on 8th May.
Answer:
2500
Step-by-step explanation:
let a represent the number of people that had swine flu on the 8th of May
a increased by 37.6% on the 9th of May. The 37.6% increase is equal to 3440
the equation that can be used to represent this is:
a x 1.376 = 3440
to find a, divide both sides by 1.376
a = 2500
