b) In a exam, Biraj got 350 marks and failed by 20 marks lf the percentageof pass marks is 40%, what is the full marks
Answer:
925 marks.
Step-by-step explanation:
AS Biraj had 20 less marks then the 40% pass mark must be 350+20 = 370.
370 is equivalent to 40%
So 100% = 100*370 / 40
= 925 marks.

Answer:
a = 3b = -18Step-by-step explanation:
Using the least common denominator, we have ...
[tex]2-\dfrac{x+1}{x-2}-\dfrac{x-4}{x+2}\\\\=\dfrac{2(x-2)(x+2)-(x+1)(x+2)-(x-4)(x-2)}{(x-2)(x+2)}\\\\=\dfrac{2(x^2-4)-(x^2+3x+2)-(x^2-6x+8)}{x^2-4}\\\\=\dfrac{(2-1-1)x^2+(-3+6)x+(-8-2-8)}{x^2-4}=\boxed{\dfrac{3x-18}{x^2-4}}[/tex]
The values of a and b are ...
a = 3
b = -18

Lisa, Kelly, and Maria have $56.70. If Lisa has $23.20 and Kelly has $15.05, which equation shows how much money, n, Maria has
Answer:
38.25+n=56.70
Step-by-step explanation:
23.20+15.05+n=56.70
38.25+n=56.70
Answer:
Maria has $18.45.
Explanation:
All three of them have $56.70 all together.
So you would want to add Lisa's amount with Kelly's amount to get how much they have together.
23.20 + 15.05 = 38.25
Then you take the amount of money Lisa and Kelly has together and subtract it from the total amount of money all three of them have together to get Maria's amount.
56.70 - 38.25 = 18.45
Maria has $18.45.
Check:
Add all three of there money amounts together and if you get $56.70 you got the right answer.
23.20 + 15.05 + 18.45 = 56.70

The zeros of a quadratic function are -7 and 3. Which of the following could be the function? Select all that apply.
A. F(x)=2x^2-8x-42
B. F(x)=5x^2+20x-105
C. F(x)=x^2+4x-21
D. F(x)=x^2-4x-21
The possible functions are
A. F(x)=2x^2-8x-42
B. F(x)=5x^2+20x-105
C. F(x)=x^2+4x-21
How to determine the possible equations?The zeros are given as:
x = -7 and x = 3
Rewrite as:
x +7 = 0 and x - 3 = 0
Multiply both zeros
(x + 7) * (x - 3) = 0 * 0
Evaluate the product
x^2 + 7x - 3x - 21 = 0
Evaluate the like terms
x^2 + 4x - 21 = 0
Express as a function
f(x) = a(x^2 + 4x - 21)
Where a is a constant
Let a = 1, 2 and 5 (according to the values in the options)
f(x) = 1 * (x^2 + 4x - 21) = x^2 + 4x - 21 --- option (c)
f(x) = 2 * (x^2 + 4x - 21) = 2x^2 + 8x - 42 --- option (a)
f(x) = 5 * (x^2 + 4x - 21) = 5x^2 + 20x - 105 --- option (b)
Hence, the possible functions are (a), (b) and (c)

90 miles/2 hours
30 miles/1 hour
Answer:
180 miles/ 3 hours
Step-by-step explanation:
180 miles / 3 hours is the same as 60 miles per hour
240 miles /6 hours is the same as 45 miles per hour
90 miles / 2 hours is the same as 45 miles per hour as well

2x + 3y + 5
2z + y
x + 3y
Given is that there are 6 children on a bus. Each child is wearing a hat.
Total number of children in the bus = 6
Number of children wearing a hat = 6
Fraction of children wearing a hat -
n = (Number of children wearing a hat/Total number of children in the bus)
n = 6/6
n = 1
Therefore, all 6 childrens in the bus are wearing a hat.

solution
AREA = length times width
135 = 6x multiplied by x
135=6x^2
x^2 as subject of formula
x^2=135/6

A local bakery charges $2.75 per cupcake.
Which equation best represents y, the total cost
of x number of cupcakes?
A.
y = 2.75 + x
B.
y = 2.75x
C.
x = 2.75y
D.
x = 2.75 + y
Mond
Answer:
B
Step-by-step explanation:
y = 2.75x
have a great day
Answer:
B. y = 2.75x
Step-by-step explanation: Since Y represents the total cost that means that the total cost is how ever many cupcakes one were to buy. Since each cupcake is $2.75 and you are buying X amount of cupcakes, the total would be 2.75 ~multiply~ X. Thus, giving you your final answer of y=2.75x.

You want to take 12 shirts, but you can only fit 3 in your suitcase. How many different ways can you choose shirts to pack?
Answer:
220 ways.
Step-by-step explanation:
This can be gotten by using the formula of combination in statistics.
The formula for combination is given below
nCr = n! / r!(n - r)!, where
r = total number of object, and
n = number of objects we're choosing from
Applying this to the question we have
12C3 = 12! / 3!( 12 - 3)!
12C3 = 12! / 3! * 9!
12C3 = 220
Therefore, we can choose to pack the shirts in 220 different ways
