Answer:
Radius, r = 26.57 cm and diameter = 53.14 cm
Step-by-step explanation:
Given that,
The circumference of a coin, C = 167 cm
We need to find the radius and the diameter of the coin.
The formula for the circumference of a circle is given by :
Where
r is radius of coin
Diameter, d = 2r
d = 2(26.57) cm
= 53.14 cm
Hence, this is the required solution.
Question: Please help lily team won 8 out of 12 games.At that rate,how many games will her team win if it plays 21 games?The ratio is now: 8 : 12 = X : 21, where x is the unknown value of win they have and 21 is the total number of games they played=> 8 : 12 = x : 21=> 8 * 21 = 168 / 12 = 14Thus, the new ratio is 8 : 12 and 14 : 21they will be winning 14 games out of 21 plays<span>

The quotient, written in scientific notation, is equal to 2.5*10¹⁰
<h3>
How to solve the quotient?</h3>
Here we have a quotient between two numbers in scientific notation:
(2.275*10¹⁹)/(9.1*10⁸)
Using the associative property, we can rewrite the quotient as:
(2.275*10¹⁹)/(9.1*10⁸) = (2.275/9.1)*(10¹⁹/10⁸) = 0.25*10¹⁹⁻⁸ = 0.25*10¹¹
Finally, remember that we need to have a digit at the left of the decimal point, then to have the outcome in scientific notation:
0.25*10¹¹ = 2.5*10¹⁰
The correct option is the last one.

In average, your monthly income is $2,557.91
<h3>How much did you earn per month, on average?</h3>
We know that in the year you win a total of $30,694.95, and we want to know how much you win per month.
We know that in a year there are 12 months. To get how much you win, in average, in one of these months, you need to take the quotient between the total amount that you earn in one year, and the number of months in a year.
It gives:
N = $30,694.95/12 = $2,557.91
In average, your monthly income is $2,557.91
