The cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55. The cost of 3 kg of mushrooms and 4 kg of turnips is £13.10. Work out the cost of a) 1 kg of turnips. b) 1 kg of mushrooms. check image
If the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10, then cost of 1 kg of turnips is £1.1 and cost of 1 kg of mushrooms is £2.9.
Given that the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10.
We are required to find the cost of 1 kg of mushrooms and the cost of 1 kg of turnips.
Cost is basically the expenditure that we do in order to buy or produce a product.
Suppose the cost of 1 kg of mushrooms be x and the cost of 1 kg of turnips be y. The equations will be as under:
2x+2.5y=8.55------1
3x+4y=13.10-------2
Equation1 *3 and Equation2 *2.
6x+7.5y=25.65-----3
6x+8y=26.20-------4
Subtract 4 from 3.
6x+7.5y-6x-8y=25.65-26.20
-0.5y=-0.55
y=1.1
Put the value of y in 1.
2x+2.5*1.1=8.55
2x+2.75=8.55
2x=8.55-2.75
2x=5.80
x=2.9
Hence if the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10, then cost of 1 kg of turnips is £1.1 and cost of 1 kg of mushrooms is £2.9.

Given details in the question are as follows:
Jim Bouche is married but is filing a separate tax return. His taxable income is $23,624,
By using the given tax table on the screenshot we are calculating the tax paid by Jim.
if your taxable income is greater than the $23,600 but lesser than the $23,624 and you fill separate tax return, the amount will be paid as tax is
$ 3,765.
what is a separate tax return?Married filing separately is a tax status for married couples who choose to record their respective incomes, exemptions, and deductions on separate tax returns.
The alternative to married filing separately is married filing jointly. Usually, it makes sense financially for married couples to file jointly. However, when one spouse has significant medical expenses or miscellaneous itemized deductions, or when both spouses have about the same amount of income, it might be wiser to file separately.

a = 71°
I hope this helps!
Answer:
a = 71°
Step-by-step explanation:
Hello!
The sum of angles on a line is 180°. That means, 109° and a have to add up to 180°.
Angles that add up to 180° are called supplementary angles.
Solve for a180° - 109° = a71° = aa is 71°.
the price of a scooter and a cycle are in the ratio 5:2 if the scooter costs ruppes 4,200 more than the cycle ,whats the price of the cycle
The price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000
Let the price of the cycle be x
Then the price of the scooter will become X + 4200
As the price of a scooter and the price of a cycle are in the ratio of 5:2
So, it can be written as
x+4200: x:: 5:2
which implies
x= 2a and x+4200= 5a
a= x/2 and x+4200/5
equating both the equations, we get
x/2=(x+4200)/5
in order to solve this linear equation, we need to move 2 from the left-hand side to the right-hand side which would result in the change of sign from division to multiplication and we need to move 5 from the right-hand side to the left-hand side which would result in the change of sign from division to multiplication
5x=2x+8400
3x= 8400
X= 8400/3
X= 2800
So, the price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000

She was paid $15 an hour. The equation 50+15h=1250 represents the amount of money she has. 1. What could the 1250 represent in this situation? A. The amount of money she had saved before B. The amount of money she had at the end of the summer C. The amount of money she earned per hour D. The amount of money she earned per week 2. George said that 10 could not be the solution to the equation. Explain why he is correct (Hint: put 10 in the place of h). 3. Find the solution to the equation. Show your work.
The 1250 represents option B in the situation, George is correct, the solution to the linear equation is h = 80$.
What is a linear equation?
A linear equation has only one or two variables. No variable in a linear equation is raised to a power greater than one or used as the denominator of a fraction. When two values satisfying a linear equation are found and shown, all of the points on a coordinate grid fall on the same line.
Given that,
Jennifer was paid $15 per hour.
Given equation is 50+15h=1250
1)Here 1250 represent B.
Her financial situation towards the end of the summer.
Because as mentioned in the equation 50+15h=1250
Here, 50 is the money already there with her, and 15h was the amount paid to her,
So, by adding those both the amount 1250 will be the amount with Jennifer at the end of the summer.
2)Given equation is 50+15h=1250
By putting 10 in place of h (h=10)
50+15(10)=1250,
50+150=1250,
200=1250$.
Since, LHS is not equal to RHS.
Therefore, George is correct, 10 could not be the solution to the linear equation.
3) Given equation 50+15h=1250
15h=1250-50,
15h=1200,
h=1200/15,
h=80$.
Therefore, the solution for the equation h is 80$.

The functions are express as follows:
(rs)(4) = 8(r / s)(3) = 2How to solve composite functions?A composite functions is gotten from the combination of two or more functions.
Therefore,
(rs)(4) = r(4) × s(4)
r(x) = 2√x

At the end of December, the Cookie Shop had a profit of $15,000. At the end of January, their profit had decreased by 20%. Type the answer in the box to represent the Cookie Shop's profit at the end of January.
The Cookie Shop's profit at the end of January will be $12000.
The profit earned by the shop at the end of December = $15000
The profit decreased by 20% at the end of January
Therefore decrease percentage, which is used to determine the percentage decrease of two values (final value and initial value)
[tex]Decrease percentage = \frac{Final value - Initial Value}{Final Value} * 100[/tex]
According to the formula, the initial value is subtracted from the final value. The resulting value is divided by the initial value and multiplied by 100 to obtain the decreased percentage
Decrease Percentage 20%
Final value = $15000
[tex]20 = \frac{15000 - Initial Value}{15000} * 100[/tex]
[tex]\frac{20}{100} = \frac{15000 - Initial Value}{15000}[/tex]
[tex]\frac{20}{100} * 15000 ={15000 - Initial Value}[/tex]
20 * 150 = 15000 - Initial Value

A shopkeeper packed two bags of sugar each 120 Kg into 3 Kg and 2 Kg packets respectively. There were half as many 2 Kg packets as 3 Kg packets. How many 3 Kg packets did he obtain?
Answer:
60
Step-by-step explanation:
Since both bags of sugar were 120 kg, there is a total of 240 kg of sugar to be distributed into the packs. Let x represent the number of 2 kg packets and y represent the number of 3 kg packets. We know that all the sugar was packed into these two kinds of packets, so:
[tex]2x+3y=240[/tex]
And we know that there were half as many 2 kg packets as 3 kg packets, so:
[tex]x=\frac{1}{2} y[/tex]
Now, we have a system of equations!
[tex]\left \{ {{2x+3y=240} \atop {x=\frac{1}{2}y }} \right.[/tex]
Let's put the second equation equal to y, since that removes the fraction:
[tex]x=\frac{1}{2}y\\ 2x=y[/tex]
Now substitute y into the first equation:
[tex]2x+3y=240\\2x+3(2x)=240[/tex]
Now simplify to find x:
[tex]2x+3(2x)=240\\2x+6x=240\\8x=240\\x=30\\[/tex]
There are 30 of the 2 kg packets! Now, we can use x to find y, the number of 3 kg packets!
[tex]2x=y\\2(30)=y\\60=y[/tex]
There are 60 of the 3 kg packets!

the required area of shaded part is 549.3807mm^2
Four quarter circles are cut out from a 16 cm square
that is we have given that square has each side 16 cm
we know that
area of square = (side) ^2
= 16*16 cm^2
= 256 cm^2
four quarter circles are cut out from a 16 cm square

area of sector = N/360 ( pi *r^2)
= 90/360( pi* 8^2) it makes angle 90 degree and r=8cm
= 1/4( pi* 64)
therefore area of four quarter circles is given by
