Answer:

Hi there!

The correct answer to this question is: 56.55

Step-by-step explanation:

A semicircle is another way of saying half a circle, if we know the area of a circle is A= π * r^2   then all we have to do is take this equation and divide it by  two to get the area of a semicircle. Additionally since we are given the diameter we need to divide that by 2 to get the radius which is six.

Now we can plug all the components into the equation: A= (1/2)(π)(6^2)

you get 56.55

(please!!!) What fraction is equivalent to 38%?
Aleks04 [339]

Answer: 19/50

Step-by-step explanation: To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. In this case, 38% can be written as the ratio 38 to 100 or 38/100. Notice however that 38/100 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 38 and 100 which is 2.

38 ÷ 2 = 19

100 ÷ 2 = 50

<em>Therefore, 38% can be written as the fraction 19/50 which is in lowest terms.</em>

if one more freaking person tell me that 120 / 37 is 3 with a decimal I'm going to delete this app because it is just three
lawyer [7]
But 37 is not a factor of 3, in fact it is a prime number so anything that is divisible by it (other than 1) will be a decimal. So, my friend here you have another person on this app telling you that it is not 3 and is in fact 3.2432 (;;;

a salesperson earns $25 per day plus $2.50 for every sale. He normally earns $100 per day. How many sales does he normally get.
Dahasolnce [82]
He makes about 30 sales because he makes $100 typically but always makes a minimum of $25 making $75 worth of his sales. If you multiply 30 and $2.50 you get $75 in sales. His $25 minimum and $75 in sales make $100. So he makes 30 sales.
