If the marked price of an article is Rs. x, discount amount is
Rs. y and the VAT amount is Rs. 2, Calculate the selling
price of the article including VAT.
Answer:
Rs. (x - y + 2)
Step-by-step explanation:
The marked price is the price that a product is to be sold. The product can be sold at a discount which is below the marked price of the product.
The marked price of the article is Rs. X. The discount is Rs. y, therefore the article price = marked price - discount = x - y.
But since the article is sold with a VAT of Rs. 2, the VAT is added to the price, therefore the selling price of the article including VAT is Rs. (x - y + 2)

10. While at the beach, Daniel buys lunch for
his family from a food stand. He purchases
one hot dog for $2.50 and 3 hamburgers. If he
spent $ 13 total, write and solve an equation to
find h, the amount each hamburger cost.
Answer: Each hamburger cost $3.50
Step-by-step explanation:
He spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equation,
2.50 + 3h = 13 Now solve for x
-2.50 2.50
3h = 10.50
h = 3.50
Check:
2.50 + 3(3.50) = 13
2.50 + 10.50 = 13
13= 13

A ball is thrown starting at a time of O and a height of 2 meters. The height of the ball follows the function
H(t)= -4.9t^2 +25t +2. What is the height of the ball at each second from 0 to 5?
Answer:
0 - 1 - 2 - 3 - 4 - 5
2 - 22.1 - 32.4 - 32.9 - 23.6 - 4.5
Step-by-step explanation:
The function is:
H(t) = -4.9t^2 +25t +2Calculating the value of H for each value of t from 0 to 5
H(0) = 2H(1) = -4.9*1^2 + 25*1 + 2 = 22.1H(2) = - 4.9*2^2 + 25*2 + 2 = 32.4H(3) = -4.9*3^2 + 25*3 + 2 = 32.9h(4) = -4.9*4^2 + 25*4 + 2 = 23.6H(5) = - 4.9*5^2 + 25*5 + 2 = 4.5Correct answer choice is the 3rd one or C

what is half the sum of x and y decreased by one-third y as a algebraic expression
Answer:
1/2(x+y) - 1/3
Step-by-step explanation:
I think this may be the answer based on the info you've given
Answer:
[tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex]
Step-by-step explanation:
We can translate these words into an expression by just reading them and interpreting them.
Half the sum of x and y.
We know that it's going to include [tex](x+y)[/tex], and if we're taking half of that, we multiply that by [tex]\frac{1}{2}[/tex], so [tex]\frac{1}{2}(x+y)[/tex]
We also know that one third of y will be multiplying y by [tex]\frac{1}{3}[/tex], so [tex]\frac{1}{3}y[/tex].
Since we are decreasing [tex]\frac{1}{2}(x+y)[/tex] by [tex]\frac{1}{3}y[/tex], there's a minus sign between the terms.
So, [tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex].
Hope this helped!

If you had 6 million dollar and you divided that by 1 billion what would you get. Then once you find that multiply your answer by 10. What do you get.
Answer: You get 0.06 which is 6 cents in terms of money.
Step-by-step explanation:
6 millions could be written as 6,000,000 and 1 billion could also be written as 1,000,000,000 so using this set up a fraction to divide it.
[tex]\frac{6000000}{1,000,000,000}[/tex] = 0.006
0.006 * 10 = 0.06
evaluate the expression
Answer: 85
Step-by-step explanation:
To solve this problem, we want to use the order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.
------------------------------------------------------------------------------------------------------------
20÷(5-3)+5²(3) [solve parenthesis]
20÷(2)+5²(3) [solve exponent]
20÷2+25(3) [solve multiply or divide, left to right]
10+75 [solve add or subtract]
85
Answer:
85
Step-by-step explanation:
To evaluate the expression, follow the rule of PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
[tex]20 \div (5-3) +5^2(3)[/tex]
Solve inside the parentheses first by subtracting 3 from 5.
5-3 = 2
[tex]20 \div (2) +5^2(3)[/tex]
Next, evaluate the exponent.
5² = 5*5= 25
[tex]20 \div 2+25(3)[/tex]
Next, multiply 25 and 3.
25 *3 =75
[tex]20 \div 2+75[/tex]
Then, divide 20 by 2.
20/2=10
[tex]10+75[/tex]
Finally, add 10 and 75.
[tex]85[/tex]
The expression [tex]20 \div (5-3) +5^2(3)[/tex] evaluated is 85.

In a city, the record monthly high temperature for March is 56 degrees Fahrenheit. The record monthly low temperature is -4 degrees Fahrenheit. What Is the range of temperature for March?
Answer:
60 degrees.
Step-by-step explanation:
In mathematics, a "range" is described as the difference between the lowest and highest numbers in a data set. To find the range, we must subtract. (This is what the word "difference" indicates in math)
56 - (-4) =
56 + 4 = 60 (the negative signs cancel out)
Thus, the range of temperature for March is 60 degrees :) Hope this helped!

45% of the pizzas in the freezer in the store are cheese pizzas. There are 120 pizzas in the
freezer. How many of them are cheese pizzas?
Answer:
54 cheese pizzas
Step-by-step explanation:
We know that there are 120 pizzas in the freezer, and 45% of them are cheese pizzas.
We want to find out how many cheese pizzas are in the freezer, so we should multiply 45% and 120.
45% * 120
Convert 45 % to a decimal. Divide 45 by 100 or move the decimal place 2 spots to the left.
45/100= 0.45 or 45.0 --> 4.5 ---> 0.45
0.45 * 120
Multiply 0.45 and 120
54
54 cheese pizzas are in the freezer.

D A farmer watered 10/82 of a field. What decimal is
equivalent to the fraction of the field the farmer
watered?
type here
Answer:
0.1219512195122
Step-by-step explanation:
To write 10/82 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 10 by 82 what we write down as 10/82 and we get 0.1219512195122
3/2x+1 = 13
find x.
What is x?
Answer:
8
Step-by-step explanation:
Please write this as (3/2)x + 1 = 13.
Start the process of solving for x by subtracting 1 from both sides:
(3/2)x = 12
Eliminate the fractional coefficient by multiplying both sides by 2/3:
(2/3)(3/2)x = (2/3)(12), or
x = 8

Which function is not defined at 0? Please help urgent
Answer:
b and g
Step-by-step explanation:
a. is y = 0³ = 0
b. is y = ln(0), which is undefined because ln(x) is only defined for x > 0
c. is y = 1 / (1 + e^-0) = 1 / (1 + 1) = 1/2
d. is y = 0
e. is y = 0² = 0
f. is y = sin(0) = 0
g. is y = 1/0, which is undefined because division by 0 is undefined
h. is y = e^0 = 1
i. is y = |0| = 0
j. is y = √0 = 0
Give an example of a set of ordered pairs that has five elements in its domain and four elements in its range.
Answer:
[ (-1,0) (0,0) (1,1) (2,2) (3,3) ]
Domain = { -1,0,1,2,3 }; Range = { 0,1,2,3 }
Step-by-step explanation:
Set or collection of ordered pairs is called 'Relation'. The ordered pairs are in terms f x & y coordinate.
Eg : [ (-1,0) (0,0) (1,1) (2,2) (3,3) ]
Domain is a set of all x axis values. Range is a set of all y axis values. They are arranged non repetitively in ascending order.
Domain = { -1,0,1,2,3 }
Range = { 0,1,2,3 }
As mentioned : the relation has been designed, as such to have five elements in its domain and four elements in its range
How much will it take to do a work of 190J with 15w power
Answer:
[tex]\Huge \boxed{\mathrm{12.67 \ s}}[/tex]
Step-by-step explanation:
[tex]\displaystyle power \ (W) = \frac{work \ done \ (J)}{time \ (s)}[/tex]
[tex]\displaystyle P= \frac{W}{t}[/tex]
[tex]\displaystyle 15= \frac{190}{t}[/tex]
Solve for t.
Multiply both sides by t.
[tex]15t =190[/tex]
Divide both sides by 15.
[tex]\displaystyle t= \frac{190}{15}[/tex]
[tex]t \approx 12.67[/tex]
[tex] \bf \underline{ \underline{given : }}[/tex]
Work = 190 JPower = 15 W[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]
Calculate the time ?
[tex]\bf \underline{ \underline{
Formula \: applied :}}[/tex]
[tex] \boxed{ \bf{Power = \frac{Work \: done}{Time} }}[/tex]
[tex]\bf \underline{ \underline{Solution : }}[/tex]
We know,
[tex]\sf {Power = \dfrac{Work \: done}{Time}}[/tex]
[tex] \sf{ Time = \dfrac{Work \: done}{Power } }[/tex]
Substituting the values of work and power, we get:
[tex] \sf \implies{Time = \dfrac{190}{15} }[/tex]
[tex] \sf\implies{Time = 12.66 \: s}[/tex]
Thus,the time taken by a body is 12.66 seconds.
