To obtain an average (arithmetic mean) of exactly 2/3, what fraction must be added to 1/6, 1/2, and 1/3?

ollegr [7]

Answer:

D. 5/3

Step-by-step explanation:

$\frac{1/6+1/2+1/3+x}{4} =2/3$

$1/6+1/2+1/3+x=8/3$

$x=8/3-1/6-1/2-1/3$

$x=8/3-1/6-3/6-2/6$

$x=8/3-6/6$

$x=16/6-6/6=10/6$

simplified

$x=5/3$

Use the formula A=bhto find the area of the parallelogram.<br> 2.1 m<br> 6.3 m

Feliz [49]

Answer:

A = 13.23 m²

Step-by-step explanation:

A = bh

Where,

A = area of the parallelogram

b = base of the parallelogram

h = height of the parallelogram

From the question, assume

b = 2.1 m

h = 6.3 m

A = bh

= 2.1 m × 6.3 m

= 13.23 m²

A = 13.23 m²

11) the difference between the product of 4 and a<br><br> number and the square of the number

marta [7]

Answer:

$= 4x-x^2\\\\$

Step-by-step explanation:

Let the number be x;

The product of 4 and the number will be;

$= 4 * x\\\\= 4x$

The the square of the number is given as;

$= x^2\\$

Taking the difference of both expressions above;

$= 4x-x^2\\\\$

Factor out the common term:

$= x(4-x)\\\\$

Hence the difference between the product of 4 and a number and the square of the number is $= 4x-x^2\\\\$
