ROC is often used while speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; the rate of change is represented by the slope of a line.

One of the numbers increased by 10. How did the average of the two numbers change?

bezimeni [28]

Hello from MrBillDoesMath!

Answer:

The average is increased by 5

Discussion:

Let x be one number and y the other number.

Average of x,y = (1/2) ( x + y)

if, say, x is increased by 10 then the average of the numbers is

( ( x+ 10) + y) /2

= (x+y)/2 + 10/2 => (x+y)/2 is the average of the original numbers

= (x+y)/2 + 5

So the average is increased by 5

Thank you,

MrB

2 5/7+4 3/5= help please

Ainat [17]

Answer:

$7\frac{11}{35}$

Step-by-step explanation:

$2\frac{5}{7}+4\frac{3}{5}$

add the whole numbers

$2+4=6$

combine the fractions

$\frac{5}{7}+\frac{3}{5}$

LCM is 35 because 7 * 5 =35

$\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}$

$\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}$

$\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}$

$=\frac{46}{35}$

change the improper fraction into mixed number

$6+1\frac{11}{35}$

$=7\frac{11}{35}$
