Answer:
the first one and the third one
Step-by-step explanation:
Answer:
4.17% (nearest hundredth)
Step-by-step explanation:
percent change = [ (difference between initial value and final value) ÷ initial value] x 100
⇒ percent change = [ (50 - 48) ÷ 48 ] x 100 = 4.17% (nearest hundredth)
Answer:
49 litres of petrol are needed to travel from town X to town Y and back.
Step-by-step explanation:
Well, first off, the variable X and Y, as well as the distance given (124 km) aren't important pieces of information in this equation. They're only there to throw you off and confuse you.
25L of <em>p</em> (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less <em>p</em> than before it was tuned.
2%/100 = 0.02
0.02 * 25L = 0.5L
25L - 0.5L = 24.5L
Now, don't forget, at the end of the word problem we're asked how many litres of <em>p</em> would be required to travel from <em>x</em> to <em>y</em> <em><u>AND BACK</u></em>. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)
Good luck!!
The gradient of the given graph is 1.5
<h3>Calculating Gradient </h3>
From the question, we are to determine the gradient of the graph
Gradient is given by the formula
Where m is the gradient
Picking the points (-2, -2) and (2, 4) on the line
Then,
x₁ = -2
y₁ = -2
x₂ = 2
y₂ = 4
Putting the parameters into the equation, we get
m = 1.5
Hence, the gradient of the given graph is 1.5
