Complete Question:
Jenny is going to tile her kitchen floor of area 30 m^2. She has taken out all the furniture and appliances. Jenny wants to know if she has got enough money to buy the tiles.The tiles are sold in packs, which cover 2m2 Jenny has a discount card which gives her 25% off any marked price at the DIY shop. The tiles are marked at £9.60 Jenny has £100 to spend on the tiles. How much extra does Jenny need to buy the tiles? Give your answer in pence.
Answer:
Extra amount needed by Jenny to buy the tiles = £8
Step-by-step explanation:
Floor area = 30.0 m^2
Area covered by a pack of tiles = 2.0 m^2
Number of packs needed = 30/2
Number of packs needed = 15
Price of a pack of tiles = £9.60
Discount = 25%
Jenny will pay 75% of the marked price
Amount Jenny will pay for a pack of tiles = 75% of 9.60 = 0.75*9.60
Amount Jenny will pay for a pack of tiles = £7.20
Amount Jenny will pay for 15 packs of tiles = 7.20 x 15
Amount Jenny will pay for 15 packs of tiles = £108
The amount of money Jenny currently has = £100
Extra amount needed by Jenny to buy the tiles = £108 - £100
Extra amount needed by Jenny to buy the tiles = £8
Answer:
The root of the equation 
is x ≈ 0.162035
Step-by-step explanation:
To find the roots of the equation you can use the Newton-Raphson method.
It is a way to find a good approximation for the root of a real-valued function f(x) = 0. The method starts with a function f(x) defined over the real numbers, the function derivative f', and an initial guess 
for a root of the function. It uses the idea that a continuous and differentiable function can be approximated by a straight line tangent to it.
This is the expression that we need to use
For the information given:
For the initial value you can choose 
although you can choose any value that you want.
So for approximation 
Next, with 
you put it into the equation
, you can see that this value is close to 0 but we need to refine our solution.
For approximation 
Again we put 
into the equation
this value is close to 0 but again we need to refine our solution.
We can summarize this process in the following table.
The approximation 
gives you the root of the equation.
When you plot the equation you find that only have one real root and is approximate to the value found.

Step-by-step explanation:
Diana is painting statues. She has 1/4 <span>of a gallon of paint remaining. Each statue requires 1/8</span><span> </span><span>of a gallon of paint. how many statues can she paint?</span>
16 inches.
There are four sides on a square, and if each side is 4 inches, multiply the 4 sides by 4 inches.
4 x 4 = 16
