There are 8 rows of chairs in the auditorium. Three of the rows are empty. What fraction of the rows are empty?

1 answer:

6 0

3 rows out of a total of 8 being empty means a fraction of 3/8 are empty.

This is because the denominator is the total. The total in this case is 8 rows.
The numerator is the number of these rows that are empty. In this case, this is 3 rows.

So the answer is 3/8 of the rows are empty.

Find the greatest common factor of 10, 30,10,30,10, comma, 30, comma and 454545.

borishaifa [10]

Answer:

GCF = 5

Step-by-step explanation:

Given:

The numbers are given as:

10, 30 and 45

A factor of a number is a number by which the given number is evenly divisible.

Example: 2 is a factor of 4 as $4\div 2 =2$ . So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.

Now, factors of 10 = 1, 2, 5, 10.

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.

Factors of 45 = 1, 3, 5, 9, 15, 45.

So, the greatest common factor in all the three numbers is 5.

Hence, the greatest common factor of 10, 30 and 45 is 5.

How do you factor and expression

Jlenok [28]

Answer: Find the greatest common factor, and put in parentheses outside of the expression

Step-by-step explanation:

The greatest common factor is the largest number that all terms are divisible by. Here is an example: 4x+8y+12 In this example the greatest common factor is 4. So, first we divide the expression by 4 and put it in parentheses, giving us (x+2y+3). However, (x+2y+3) does not equal 4x+8y+12. We need to put the 4 we divided by in front of the parentheses, giving us 4(x+2y+3), which does equal 4x+8y+12. Hope this helps

A movie theater sends out a coupon for 85% off the price of a ticket. Write an equation for the situation, where y is the pri

ra1l [238]

Answer:

$y=0.15x$

Step-by-step explanation:

Given:

Original price of the ticket is $x$

Price after using the coupon is $y$

Coupon discount is 85% of $x=0.85x$

Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

$y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x$

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.

The line $y=0.15x$ strictly remains in the first quadrant as both $x$ and $y$ can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of $x$ and $y$ positive.
