Answer: 40%

Step-by-step explanation:

To write 8/20 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % . 8/20 * 100 = 0.4 * 100 = 40% And finally we have: 8/20 as a percent equals 40%

If the expression 2x/a plus b = c is solved for x in terms of a, b, and c, then x = what?

Doss [256]

Answer:

The value of x in terms of a, b ans c is $x=\frac{ac-ab}{2}$

Step-by-step explanation:

We have given the expression $\frac{2x}{a}+b=c$

We have to find the value of x in terms of a, b and c

So $\frac{2x}{a}+b=c$

$\frac{2x}{a}=c-b$

$2x=a(c-b)$

$2x=ac-ab$

$x=\frac{ac-ab}{2}$

So the value of x in terms a ,b and c is $x=\frac{ac-ab}{2}$

if a point a device line segment a b of length 10 centimetre internally In the ratio 2:3 then find the length of a d

Debora [2.8K]

Given:

Consider a point d divides line segment ab of length 10 centimetre internally in the ratio 2:3.

To find:

The length of ad.

Solution:

If a point d divides line segment ab internally in the ratio 2:3, then the length of ad and db are 2x and 3x receptively.

We know that,

$ab=ad+db$

Length of the segment ab is 10 cm.

$10=2x+3x$

$10=5x$

Divide both sides by 5.

$2=x$

Now,

$ad=2x$

$ad=2(2)$

$ad=4$

Therefore, the length of segment ad is 4 centimetres.

We throw two dice. Each die is a standard die that has 6 sides and is numbered 1 to 6. Let X represent the sum of the two dice.

Verdich [7]

Answer:

total number of possible outcome is 36

Step-by-step explanation:

if the two dice are thrown simultaneously and we set out the possible combinations;

for example,

(1,1) (1,2), (1,3) (1,4) (1,5) (1,6), (2,1) (2,2) (2,3) .... in that order, we will discover that the most probable even is an outcome of 36
