Natalie makes potato cakes in a restaurant.
She mixes potato, cheese and onion so that
weight of potato:weight of cheese :weight of onion = 9: 2:1
Natalie needs to make 6000g of potato cakes.
Cheese costs £2.25 for 175 g.
Work out the cost of the cheese needed to make 6000g of potato cakes
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,
[tex]9x+2x+1x = 6000\\\\12x = 6000\\\\x = 500[/tex]
Hence, the value of x is 500.
Thus, the amount of cheese that will be needed is 2x,
[tex]2x = 2 \times (500) = 1000g[/tex]
Given that the cost of 175g of cheese is £2.25, therefore, the cost of 1g of cheese will be,
[tex]\text{Cost of 1g cheese} = \£\dfrac{ 2.25}{175}[/tex]
Now, the cost of 1000g of cheese will be,
[tex]\text{Cost of 1000g cheese} = 1000\times \£\dfrac{ 2.25}{175} = \£12.86[/tex]
Hence, the cost of cheese that is needed to make 6000g of potato cake is £12.86.

How to find the side length of a similar triangle?In mathematics, two triangles are said to be similar provided that they have the same ratio of corresponding sides and equal pair of corresponding angles.
Now, from the given image, we can see that DE bisects AC into 2 equal parts and by virtue of the concept of similar triangles, we can say that;
DE/BC = 1/2
We are given;
DE = x + 1
BC = 4x - 6
Thus;
(x + 1)/(4x - 6) = 1/2
Cross multiply to get;
2x + 2 = 4x - 6
4x - 2x = 6 + 2
2x = 8
x = 4

What’s the median for 28,30,30,30,30,31,31,31,31,31,31,31,31
Answer:
31
Step-by-step explanation:
The median is the number that we find in the middle of the data.
So if we have a sequence of {1,2,3}
Then 2 is the median
If we have a sequence of {1,2,3,4,5}
Then 3 is the median
We look in the middle of 28,30,30,30,30,31,31,31,31,31,31,31,31
and we find 31 in the middle.
Note:
If the middle is something with 2 terms in the middle like
1,2,3,4
Then the median is the average of the two middle terms which is
(2+3)/2 = 2.5

Have a good day ;)
Answer:
x = 4
Step-by-step explanation:
Given equation:
3x - 4 = 8To determine the value of "x", we need to isolate the "x" variable and it's coefficient. This can be done by adding 4 to both sides of the equation.
⇒ 3x - 4 + 4 = 8 + 4⇒ 3x = 12The next step in determining the "x" variable is to isolate the coefficient from the "x" variable. This can be done by dividing 3 both sides of the equation.
⇒ 3x/3 = 12/3⇒ x = 4Therefore, the solution (x) is 4.
What is the slope-intercept equation for this line?
--1
y = [?]=x +
Enter the correct
symbol,+ or -.
-2
-3
Answer:
y = -1/2x - 2
Step-by-step explanation:
Slope Intercept form: y=mx+b
You need to find the slope and y-intercept.
(0,-2) is the y-intercept which is the point on the y-axis that is intersected by the linear equation which is our slope line.
Now, we need to find our slope.
*This line is a negative slope*
Starting at our y-intercept [ (0,-2) ] we need to go to a point where the line intersects.
The red dot on the coordinate plane clearly represents it.
(2,-3) is the red point in which we need to go down 1 and over 2 to get there.
So our slope should be -1 / 2
Lastly, write in slope-intercept form:
y = -1/2x - 2

Answer:
[tex]x=4y^2-24y+30[/tex]

Step-by-step explanation:
Standard form of a sideways parabola: [tex]x=ay^2+by+c[/tex]
Given equation:
[tex]4y^2-x-24y+30=0[/tex]
Add x to both sides:
[tex]4y^2-24y+30=x[/tex]
[tex]\implies x=4y^2-24y+30[/tex]
--------------------------------------------------------------------------------------------
Standard form of circle equation
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a,b) is the center and r is the radius)
Given equation:
[tex]2x^2+2y^2-18x-10y+7=0[/tex]
Group like terms:
[tex]2x^2-18x+2y^2-10y+7=0[/tex]
Divide by 2:
[tex]x^2-9x+y^2-5y+3.5=0[/tex]
Factor by completing the square for each variable:
[tex](x-4.5)^2-20.25+(y-2.5)^2-6.25+3.5=0[/tex]
Rearrange into standard form:
[tex](x-4.5)^2+(y-2.5)^2=23[/tex]
Therefore, the circle has a center at (4.5, 2.5) and a radius of √23
You measure 20 dogs' weights, and find they have a mean weight of 41 ounces. Assume the population standard deviation is 11.9 ounces. Based on this, what is the maximal margin of error associated with a 99% confidence interval for the true population mean dog weight.
Give your answer as a decimal, to two places
Answer:
(34.15, 47.85)
Step-by-step explanation:
[tex]n = (\frac{z*stddev}{ME} )^{2}[/tex]
stddev = 11.9
z = invNorm(
area = (1 + confidence interval)/2
mean = 0
stddev = 1
)
= invNorm(
0.995
0
1
)
≈ 2.576
n = 20
square root both sides
[tex]\sqrt{20} = 2.576 * 11.9 / ME[/tex]
multiply both sides by ME, divide both sides by √20 to isolate ME
ME = 2.576 * 11.9/√20
≈ 6.85
interval = mean ± ME

If the sides of a triangle are 8 and 11 in units and the angle between them is 37 degrees, then the length of the third side is: Options :
A 6.1 B 6.4 C 6.7 D 6.9
The question is an illustration of the laws of cosine, the length of the third side is 6.7 units
How to determine the third side?The measure of the third side is calculated using the following law of cosine
a^2 = b^2 + c^2 - 2bc * cos(A)
So, we have:
a^2 = 8^2 + 11^2 - 2 * 8 * 11 * cos(37)
Evaluate the expression
a^2 = 44.44
Take the square root of both sides
a = 6.7
Hence, the length of the third side is 6.7 units
