If 120 marks is 60% what is full marks

ivanzaharov [21]

Percentage is a value by a fraction of 100.
120 marks is equivalent to 60%
this means from the whole amount, 60 % of the whole amount is 120 marks
we need to find the full marks
if 60 % --- 120
then 1 % --- $\frac{120}{60}$
full marks are 100 %
therefore 100 % - $\frac{120}{60} * 100$
100 % --- 200 marks
full marks are 200 marks

The data in the table represents a company’s profit based on the number of items produced

frutty [35]

Answer:

(A) y= -1.026x^2 + 1016.402x - 162075

Step-by-step explanation:

Here is the options to the question

Which equation best represents the data?

A) y= -1.026x^2 + 1016.402x - 162075

B) y= -1.036x^2 + 1024.771x - 163710

C) y= 298.214x - 66317.667

D) y= 196.2x – 18710

(A) y= -1.026x^2 + 1016.402x - 162075

The data above represents the company's profit based on number of items produced.

To get the equation which best represents the data, we have to substitute the value of x into the given equations

By substituting x=100 in first equation, we have:

y = -1.02x² + 1016.402x – 162075

y = -1.026(100)² + 1016.402(100) – 162075

y = -70500

Option A satisfies.

Using the second equation

When x = 100

y = -1.036x^2 + 1024.771x - 163710

y = -1.036(100)² + 1024.771(100) - 163710

y = -10360 + 102477.1 – 163710

y = -71592.9

Option B doesn’t satisfies

We can also replace the various values of x in the equations to check whether or not they satisfy.

Connor had 37 green marbles. Then he bought 3 bags of blue marbles. There were 6 marbles in each bag. How many marbles does Conn

ycow [4]

Answer:

55 marbles.

Step-by-step explanation:

You multiply 3 and 6 and that equals 18. You multiply the numbers together because you know he has 3 bags of marbles and he has 6 marbles in each bag. Then you take the 18 marbles and add them together with the 37 marbles and you get 55 marbles.
