The sum of 3 consecutive even integers is 576. Find the integers

1 answer:

4 0

You can write the equation
x+1+x+3+x+5=576
Combine like terms
3x+9=576
Subtract 9 from both sides
3x+9-9=576-9
3x=567
Divide both sides by 3
3x/3=567/3
x=189
The first integer is 190, the second is 192 and the third is 194 (enter it into the original equation to get those answers)

The value of the solid's surface area is equal to the value of the solid's volume. Find the value of x.

USPshnik [31]

Volume = (l * w * h) or (11 * 3 * x) which will equal surface area. Volume is 33x for now

Surface Area = 2 (x * 11) + 2 (x * 3) + 2 (11 * 3)

Set Volume equal to surface area. I simplified SA already.
33x = 22x + 6x + 66

33x - 28x = 66

5x = 66

x = 66/5 or 13.2

Marlon asks a friend to think of a number from 5-11. What is the probability that marlins friend will think of the number 9

Tju [1.3M]

Answer:

14.29% probability that Marlon's friend will think of the number 9

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)

9 is one of them

$p = \frac{1}{7} = 0.1429$
