Answer:
He has 5 ways to arrange them in a array.
Step-by-step explanation:
colby has 16 jars of spices.He wants to arrange them in arrays.
<em>An array is a systematic arrangement of similar objects, usually in rows and columns.</em>
So, the choices he could have to form an array is the possible number of ways he can arrange them in rows and columns and in table it could be seen as:
S.no. Number of rows Number of columns
1 16 1
2 8 2
3 4 4
4 2 8
5 1 16
Hence, the number if arrays he could use to arrange them is 5.
Answer:
Cost of the box of pencils = x = $4
Cost of the notebook = x+2 = 4+2 = $6
Cost of package of pens = 3x = 3(4) = $12
Step-by-step explanation:
Let the cost of the box of pencils = x
Cost of the notebook = 2 more than the pencils cost = x+2
Cost of package of pens = 3 times the pencils cost = 3x
The total was $22, so we can say:
(x)+(x+2)+(3x) = 22
5x=22-2
x=20/5
x=$4
Cost of the box of pencils = x = $4
Cost of the notebook = x+2 = 4+2 = $6
Cost of package of pens = 3x = 3(4) = $12
Answer: 1
Step-by-step explanation:
Simplify 9x+4x to 13x to get 13x=13
than dived both sides to get x=1
<h3>
Answer: c = 29</h3>
Work Shown:
Use the pythagorean theorem
a^2+b^2 = c^2
21^2 + 20^2 = c^2
441 + 400 = c^2
841 = c^2
c^2 = 841
c = sqrt(841)
c = 29
