Write 11/3 decimal. If necessary, use a bar to indicate which digit or group of digits repeats.

can someone please help me with this? I know it’s simple but I’m having a really hard time doing it .

Radius= 12÷2 => 6 cm

diameter= 12 cm

circumference = 2πr

=> 2× 22/7 × radius

=> 37.7 cm

Hope it helps ^^

What's 2 + 2 in a mathematical sense

Setler [38]

In a mathematical sense..

Not to make it too complicated, however, here's where we get on to the real mathematics.

There are infinite equations for 2 + 2. The gap between any number can be infinite if you keep giving it more numerical content. However, solving 2 + 2 can be very tricky.

1 + 1 + 1 + 1 = 4. Easy, right? Wrong. We can deduct from this equation that 1 + 1 = 2, so if we do 1 + 1 PLUS 1 + 1, (1 + 1 + 1 + 1 again), that equals four, because 1 + 1 is 2 and if we add another 1 to 2, 1 + 2, it equals 3, so 1 + 3 = 4. I'd like to remind you-- this works both ways, whether or not it's 3 + 1 or 1 + 3, it equals 4. If we carry the 1 from the three and put it in a separate number in an equation, said equation is now 1 + 1 + 2. It still equals 4, because 1 + 1 = 2 and if you take 2 and put it in 1 + 1's place, it's 2 + 2.

2 + 2 = 4.

(this was a joke answer, don't take anything said in this answer seriously.. OR you can if you want, because it's all true.. 2 + 2 = 4.)

Hope this helped!

A box contains 6 nuts, 8 bolts, and 4 screws. If 3 objects are selected in succession randomly, what is the probability of selec

olya-2409 [2.1K]

The answer is A. 8/243

There are in total 18 objects:
6 nuts + 8 bolts + 4 screws = 18 objects

The probability of choosing a nut is: 6/18 (since there are 6 nuts of total 18 objects).
The probability of choosing a bolt is: 8/18 (since there are 6 bolts of total 18 objects).
The probability of choosing a screw is: 4/18 (since there are 4 screws of total 18 objects).

Because replacement occurs each time, there are always 18 objects. Also, since selecting a nut, a bolt, and a screw occurs together, we will use the multiplication rule and multiply the probabilities of events occurring together:
$P= \frac{6}{18} *\frac{8}{18} *\frac{4}{18} =\frac{1}{3} *\frac{4}{9} *\frac{2}{9} =\frac{8}{243}$

N-1 increased by 110%

ElenaW [278]

Answer:

2.1n-2.1

Step-by-step explanation:

The increase is

1.10 (n-1)= 1.1n -1.1

Add this to the original amount

(n-1) + 1.1n - 1.1

2.1n-2.1

The mean of 3 consecutive terms in an arithmetic sequence is 10, and the mean of their squares is 394. What is the largest of th

poizon [28]

Let the numbers be:
a, a+b, a+2b
mean of the numbers is:
(a+a+b+a+2b)/3=10
(3a+3b)/3=10
a+b=10
thus second term is 10

The sum of square will be:
((10 - b)² + 10² + (10 + b)²) / 3 = 394
(100 - 20b + b² + 100 + 100 + 20b + b²) / 3 = 394
(300 + 2b²) / 3 = 394
(150+b²)=591
b²=441
b=-21,21

thus the numbers will be:
10-21, 10, 10+21
=-11,10,31
