A ratio shows us the number of times a number contains another number. The cost of cheese that is needed to make 6000g of potato cake is £12.86.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the ratio of the ingredients is,
weight of potato: weight of cheese: weight of onion = 9: 2:1
Let the ingredients be mixed in the quantity 9x, 2x, and 1x, for 6000g of potato cake. Therefore, the value of x can be written as,
\(9x+2x+1x = 6000\\\\12x = 6000\\\\x = 500\)
Hence, the value of x is 500.
Thus, the amount of cheese that will be needed is 2x,
\(2x = 2 \times (500) = 1000g\)
Given that the cost of 175g of cheese is £2.25, therefore, the cost of 1g of cheese will be,
\(\text{Cost of 1g cheese} = \£\dfrac{ 2.25}{175}\)
Now, the cost of 1000g of cheese will be,
\(\text{Cost of 1000g cheese} = 1000\times \£\dfrac{ 2.25}{175} = \£12.86\)
Hence, the cost of cheese that is needed to make 6000g of potato cake is £12.86.

Approximately 99.7% of scores lie in the shaded region.
We have,
The empirical rule, also known as the 68-95-99.7 rule, provides an estimate of the percentage of scores that lie within a certain number of standard deviations from the mean in a normal distribution.
According to this rule:
Approximately 68% of scores lie within 1 standard deviation of the mean.
Approximately 95% of scores lie within 2 standard deviations of the mean.
Approximately 99.7% of scores lie within 3 standard deviations of the mean.
Now,
In the given scenario, the shaded region represents the area between -2 and 3 standard deviations from the mean on the x-axis.
This encompasses the area within 3 standard deviations of the mean.
And,
Since 99.7% of scores lie within 3 standard deviations of the mean, we can estimate that approximately 99.7% of scores lie in the shaded region.
Therefore,
Approximately 99.7% of scores lie in the shaded region.

what is the graph of f(x) = 5(2)^x
The graph of the function f(x) = 5(2)^x is an upward-sloping exponential curve that starts at (0, 5) and increases rapidly as x moves to the right, never crossing the x-axis.
The function f(x) = 5(2)^x represents exponential growth. Let's analyze its graph.
As x increases, the value of 2^x grows exponentially. Multiplying it by 5 further amplifies the growth. Here are a few key points to consider:
When x = 0, 2^0 = 1, so f(0) = 5(1) = 5. This is the y-intercept of the graph, meaning the function passes through the point (0, 5).
As x increases, 2^x grows rapidly. For positive values of x, the function will increase quickly. As x approaches positive infinity, 2^x grows without bound, resulting in the function also growing without bound.
For negative values of x, 2^x approaches zero. However, the function is multiplied by 5, so it will not reach zero. Instead, it will approach y = 0, but the graph will never touch or cross the x-axis.
The function is always positive since 2^x is positive for any value of x, and multiplying by 5 does not change the sign.
Based on these observations, we can conclude that the graph of f(x) = 5(2)^x will be an exponential growth curve that starts at (0, 5) and increases rapidly as x moves to the right, never crossing or touching the x-axis.
The graph will have a smooth curve that rises steeply as x increases. The rate of growth will be determined by the base, in this case, 2. The larger the base, the steeper the curve. The function will approach but never reach the x-axis as x approaches negative infinity.

Write an equation with a letter for the unknown quantity to represent the situation. 2. Solve the problem. Explain or show your reasoning.
a) Using the four basic mathematical operations, the number of balloons that each person hang up is 9.
b) An equation representing the situation is x = (125 - 80)/5.
What are the mathematical operations?The four basic mathematical operations include addition, subtraction, division, and multiplication.
The mathematical operations provide solutions to mathematical problems using operands.
What is an equation?An equation is a mathematical statement showing that two or more mathematical expressions are equal or equivalent.
The total number of balloons that Andre has = 125
The number of balloons remaining after hanging some for the school party = 80
The difference (number of balloons used) = 45 (125 - 80)
The number of friends who hang the balloons = 5
The number of balloons hung by each friend of Andre = 9 (45/5)
Thus, we can conclude that each of the 4 friend and Andre hung 9 balloons, with 80 remaining.

What is the weighted average length, in cm,
of a nail from the carpenter's box?
Weighted Ave Length
Enter
The weighted average length of a nail from the carpenter's box whose distribution is give in image is: 3.5cm.
What is weighted average ?
Weighted average is a type of average that takes into account the relative importance or weight of each data point. In a weighted average, each data point is multiplied by a corresponding weight, which reflects its relative importance, and the products are then summed and divided by the sum of the weights.
To find the weighted average length of a nail, we need to multiply each nail length by its percent abundance, then add up all the products and divide by the total percent abundance.
Let's start by calculating the product of each nail length and its percent abundance:
Short nail: (2.5 cm) x (70.5%) = 1.7625 cm
Medium nail: (5.0 cm) x (19%) = 0.95 cm
Long nail: (7.5 cm) x (10.5%) = 0.7875 cm
Now, we add up all the products:
1.7625 cm + 0.95 cm + 0.7875 cm = 3.5 cm
Finally, we divide by the total percent abundance:
70.5% + 19.0% + 10.5% = 100%
Therefore, the weighted average length of a nail from the carpenter's box is: 3.5 cm ÷ 100% = 3.5cm

Step-by-step explanation:
Let x be the original price.

\(x\times(1+0.12)=560\)
\(1.12x=560\)
\(1.12x/1.12=560/1.12\)
\(x=500\)
Answer:
500Solution,
\(profit \: percent = 12 \\ selling \: price = 560 \\ cost \: price \\ = \frac{sp \times 100}{100 + profit \: percnt} \\ = \frac{560 \times 100}{100 + 12} \\ = \frac{56000}{112} \\ = 500\)

\(\begin{gathered} P=2(W+L) \\ 10.8=2(2.45+L) \\ \frac{10.8}{2}=2.45+L \\ 5.4=2.45+L \\ L=5.4-2.45 \\ L=2.95 \end{gathered}\)The length of the rectangle is 2.95.

The actual dimensions of the room is given as follows;
\(Actual \ Room \ dimensions: \ 2\frac{1}{2} \ inches \times 32 \ by \ 3\frac{3}{8} \ inches \times 32\)
Where;
\(2\frac{1}{2} = \dfrac{5}{2}\), and \(3\frac{3}{8} =\dfrac{27}{8}\)
