Answer:
Step-by-step explanation:
Two possible patters of sitting:
⇒
⇒
⇒ Three ways can be used to seat each set of three people, for a total of six.
⇒ There are two groups
2 × 3 = 6 (ways in six groups.)
*The two options can be distributed in two groups.
⇒ Total methods are equal to 6 * 6 * 2 = 72 ways.
When you want to get the quotient of two fractions you would cross multiply them.
(5/31)/(15/23) would become ((5x23)/(31x15))= (465/115) you could then simpy the top and bottom by 5 ending up with (93/23) you can simply that into a mixed fraction by dividing 23 into 93 is 4 times with 92 so the whole number is 4 and 93-92 = 1. so the numerator of the fraction is 1 and 93 remains the denominator. so the answer could also be 4(1/93).
It’s r=-2
Just by doing the work to it I got that answer
Answer:
Step-by-step explanation:
This relation (this group of points) is NOT a function. In order to be a function, every x-value (the first number in the pair) can only be paired up with one y-value (only one partner for the x)
In this relation, -6 is paired up with four different y-values (four different partners!)
If you plotted these points on a graph, you would see they are all lined up in a vertical line. If you have learned about the vertical line test, you will see that a vertical line goes through all four points. This set of points fails the vertical line test. To be a function, a vertical line can only touch the points one at a time.
To be a function, every x can only have one y partner.
Given that Lorenzo ate 2/5 of his bag of almonds, the remaining amount was:
1-2/5=3/5
Given that 4 of his friend shared the remaining fraction equally, then the amount that each one ate was:
3/5÷4
that is:
3/5 divided by 4
this can be simplified to
=3/5×1/4
=3/20
The answer is: 3/5 divided by 4
