Last week, Layla's Ice Cream Shoppe sold 11 sundaes with nuts and 39 without. what is the ratio of the number of sundaes without

kompoz [17]

The ratio of the number of sundaes with nuts to the number of sundaes without nuts is; 11:39

<h3>How to find the sharing ratio?</h3>

We are given;

Number of sundaes with nuts sold = 11

Number of sundaes without nuts sold = 39

Thus, the ratio of the number of sundaes with nuts to the number of sundaes without nuts is;

11:39

If 20% of x is y, and 30% of y is z, then what percent of x is z?

Bess [88]

Your answer is 6% of x.

We can write the given information as equations to find the answer:

Another way to write "20% of x" is to write 0.2x, so therefore 0.2x = y

You can also write "30% of y" as 0.3y, so 0.3y = z

Now we can substitute in the first equation to the second equation, as we know what y equals in terms of x:

0.3(0.2x) = z

Multiplying out we get:

0.06x = z, and 0.06 as a percentage is 6%

I hope this helps!

PLS HURRY THANK YOU.

<u>Given</u>:

The arithmetic sequence is represented in the table.

The general form of the arithmetic sequence is given by

$a_n=a_1+(n-1)d$

We need to determine the value of the missing term.

<u>First term:</u>

From the table, we need to determine the first term of the arithmetic sequence.

From the table, the value of the first term is 3.

Thus, $a_1=3$

Hence, the first term is 3.

<u>Common difference:</u>

From the table, we can determine the common difference of the arithmetic sequence.

Thus, we have;

12 - 3 = 9

Hence, the common difference is $d=9$

<u>Value of the missing term:</u>

The value of the term 45 can be determined by substituting n = 45 in the general form $a_n=a_1+(n-1)d$

Thus, we have;

$a_{45}=3+(45-1)(9)$

$a_{45}=3+(44)(9)$

$a_{45}=3+396$

$a_{45}=399$

Hence, the value of the term 45 is 399.

Thus, the value of the missing term is 399.
