a pack of 6 batteries of the same type costs £2.79.By calculating the price per battery,determine if this is better value. You must show your working
The required price of one battery from the pack is £0.465.
How we calculate the price of a battery when have a price of collection of the batteries?When we given a pack of objects with some cost, then to calculate the price of one object, divide the amount of pack by number of objects in the pack.
According to given information:we have, price of 6 battery = £2.79
Then, the price of one battery = £2.79/6 = £0.465
Thus, the the price per battery is £0.465.

SHOW ALL WORK!!!!!
Answer:
Point Slope Form: y - 0=2 (x - 0)
Simplified Form: y=2x
Step-by-step explanation:
The point-slope form of line is given by:
y - y1=m(x - x1)
Where
m is the slope
is the first x-coordinate
is the first y-coordinate
Given slope is 2, thus we can say:
m = 2
Also, it says the line goes through the point (0,0), so:
and
Now, substituting, we get the point slope form to be:
y-y1=m(x - x1)
y-0=2(r-0)
y=2(x)
y=2x
The equation of line will be y = 2x
The slope of the equation m = 2 and the point P ( x₁ , y₁ ) = P ( 0 , 0 )
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Let the point be represented as P
The value of P = P ( 0 , 0 )
The slope of the equation m = 2
Slope m = 2
Now , the equation of line in the slope intercept form is
y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 0 = 2 ( x - 0 )
On simplifying the equation , we get
y = 2x
Therefore , the value of A is y = 2x
Hence , the equation of line is y = 2x

Answer: The smallest two-digit prime number such that reversing the digits of the number produces a composite number is 19
Step-by-step explanation:
11, which is the smallest two-digit prime number, 11 remains the same number when the digits are reversed, and it is a prime number, of course.
The next two-digit prime number is 13. 13 becomes the prime number 31 when the digits are reversed.
17 is the following two-digit prime number. The result of flipping the digits of 17 is 71, a prime number.

The cost of another 2 panes of glass cost = $5.90.
A nurery owner buy 7 pane of glass to fix some damage to his greenhoue.
The 7 pane cost = $20. 65
First find the cost of one pane of glass (the "unit cost")
7 panes of glass cost $20.65, so one pane of glass costs
= 20.65 ÷ 7
= $2.95 ← cost of one pane of glass
Then use that answer to find the cost of two panes of glass
If one pane of glass costs $2.95, then 2 panes cost

A person climbs a mountain road from the base to the summit at a speed of 45 m/min and descends the same road from top to bottom at a speed of 60 m/min. When comparing the length of time, there is a 20 minute difference between the climbing and descending times. How many meters is it from the base to the summit of the mountain?
The distance between the base to the summit of the mountain is 300 meters.
Here Given that,
Person climbs a mountain road from the bas to the summit at a speed of 45 m/min.
And
descends the same road from top to bottom at a speed of 60 m/min
Now,
The time difference between the climbing and descending is 20 min.
So, we can say that
Velocity v₁=45 m/min
Velocity v₂=60 m/min
Time difference ∆t=20 min
We have to find the distance between the base to the summit.
As we know,
The formula for average velocity is
∆v=∆x/∆t
v₂-v₁=∆x/∆t
60-45=∆x/20
∆x=15×20
∆x=300 meter

Step-by-step explanation:
we have to mark the angles in the point denoted in the graph and connect it
The illustration of the dilated triangle has been shown.
What is the scale factor?The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
The vertices of a triangle are A(-4, 6), B(6.4), and C(6. - 2).
The scale factor of 1/2.,
Coordinates of the vertices of the triangle with scale factor,
A' = (-4 × 1/2 , 6 × 1/ 2)
A' = (-2, 3)
Similarly,
B' = (3, 2)
C' = (3, -1)
Thus, the illustration of the dilated triangle has been shown.

You can convert gallons to liters by using a factor of 3.79. That is, 1 gallon is about 3.79 liters. About how many liters are in 37 gallons? Is your answer an underestimate or overestimate? Explain.
140.23 liters are in 37 gallons
We have been given you can convert gallons to liters by using a factor of 3.79
That is, 1 gallon = 3.79 liters.
We need to find the amount of liters in 37 gallons.
Let 37 gallons = x liters
As we know 1 gallon = 3.79 liters.
So, by Unitary method,
x = 37 * 3.79
x = 140.23 liters
Therefore, 140.23 liters are in 37 gallons
