Step-by-step explanation:
0.0000378 in scientific notation
3.78 * 10 ^ - 5
Answer:
81
Step-by-step explanation:
We need to know the sides of the square so 36÷4=9
Area of a square = Side x side
Area of square = 9x9=81
Using it's concept, it is found that the probability of guessing the right combination in one try’s is of 
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 4 dials, each with a 
probability of getting it correct, hence the probability of getting the right combination is given by:

Answer:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
1 / 5 = 0.20
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 20
Now, we will make the Fractional Part just one digit (nearest tenth) by using our rounding rules.*
In this case, Rule I applies, so 1/5 (or 0.20) rounded to the nearest tenth in decimal format is:
<h2><u><em>
0.2</em></u></h2>
Yes, the larger one is twice the smaller one.
8*2=16
5*2=10
