Answer:

Arithmetic: 3, 8, 13, 18,... , 4, 8, 12, 16,...

Geometric: 4, 8, 12, 16,... , 2,6, 18, 54,...

Neither: 5, 10, 20, 30,...

Step-by-step explanation:

An arithmetic sequence is a sequence that grows by addition, a geometric sequence is one that grows by multiplication.

3, 8, 13, 18,... is arithmetic because you add 5 each time to find the next term of the sequence.

5, 10, 20, 40,... is geometric because you multiply the previous term by a factor of 2 each time to find the next nerm of the sequence.

2,6, 18, 54,... is geometric because you multiply the previous term by a factor of 3 each time to find the next nerm of the sequence.

5, 10, 20, 30,... is neither because it does not follow the pattern set by the rules of geometric or arithmetic sequences.

4, 8, 12, 16,... is arithmetic because you add 4 each time to find the next term of the sequence.

Rosie has some charms, c, for her charm bracelet. Ray gives Rosie 3 new charms.How many charms does Rosie have now? write an exp

marusya05 [52]

Answer:

Rosie now has c+3 charms

Explanation:

We are given that the original number of charms that Rosie has is c

We know that Ray gave Rosie 3 new charms

This means that the number of charms that Rosie originally had increased by 3

To express this increase, we use addition where we add 3 to the original number of charms that she had

New number of charms = original number of charms + 3

New number of charms = c + 3

Hope this helps :)

A postal service requires that any box sent by priority mail have length plus girth (distance around) totaling no more than 104

Vaselesa [24]

Answer:

The length is no more than 56 inches.

The volume of the box is 8064 cubic inches.

Step-by-step explanation:

Given : A postal service requires that any box sent by priority mail have length plus girth (distance around) totaling no more than 104 in. One volume that meets this condition is contained by a box with a square end 12 in. on each side.

To find : What is the length of the box? What is the volume?

Solution :

A square end 12 inch on each side.

Then the girth of the box is given by,

$P=4\times s$

$P=4\times 12$

$P=48$

The girth of the box is 48 inches.

A postal service requires that any box sent by priority mail have length plus girth (distance around) totaling no more than 104 in.

So, $L+48\leq 104$

$L\leq 56$

The length is no more than 56 inches.

The maximum volume of such a box would be,

$V=L\times B$

B = area of the base (or end) of the box,

So, $B=12^2=144$

The volume is

$V=56\times 144$

$V=8064\ in^3$

Therefore, The volume of the box is 8064 cubic inches.

A collection of 30 coins worth $5.50 consists of nickels, dimes, and quarters. There are twice as many dimes as nickels. How man

defon

Three unknowns requires three equations to solve . . .

1) n + d + q = 30
2) d = 2n
3) (0.05)n + (0.10)d + (0.25)q = 5.50

* plug 2) into 1) and solve for q

n + 2n + q = 30

3n + q = 30

q = 30 - 3n

* now we have variables d and q expressed in terms of n, so we plug those equations into 3) and solve for n . . .

0.05n + 0.10(2n) + 0.25(30 - 3n) = 5.50

0.05n + 0.20n + 7.50 - 0.75n = 5.50

(0.05 + 0.20 - 0.75)n + 7.50 = 5.50

-0.50n + 7.50 = 5.50

-0.50n = 5.50 - 7.50

-0.50n = -2.00

n = -2.00/-0.50 = 4

d = 2n = 2(4) = 8

q = 30 - 3n = 30 - 3(4) = 30 - 12 = 18

The answer is . . .

n = 4 nickels
d = 8 dimes
q = 18 quarters

. . . for a total of (4 + 8 + 18) = 30 coins
. . . 8 dimes is twice 4 nickels
. . . $0.05(4) + $0.10(8) + $0.25(18) = $5.50
