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:
0.000083
Step-by-step explanation:
When you multiply by 10^-5, you're really multiplying by 0.00001. This multiplied by 8.3 is 0.000083. It also means that you just move the decimal place in 8.3 to the left five times, where you'll get the same answer.
Answer:
Question 1: 71 and 72
Question 2: Child 1: 60 lbs, Child 2: 15 lbs
Step-by-step explanation:
Question 1:
Consecutive numbers are 2 numbers right next to each other.
You know the numbers will have to be double digits number.
71 and 72 are consecutive numbers. The sum of them is 143.
71+72=143
Question 2:
For this problem, we can use system of equations to find the mass of the 2 children. Let's say x is the first child and y is the second child.
Equation 1
x+y=75
This equation comes from the combined mass of the 2 children.
Equation 2
x=4y
This equation comes from the first child being 4 times the mass of the second child.
Since we know the value of x, we can use substitution to find y.
4y+y=75
5y=75
y=15
Now that we know the second child is 15 lbs, we can plug this into any of the 2 equations to find the mass of the first child.
x=4(15)
x=60
(- 3, 2 ) is a solution to the system of equations
To determine if the point is a solution, substitute the x and y coordinates into the left side of each equation and if equal to the right side then the point is a solution.
using x = - 3 and y = 2, then
(6 × - 3 ) + (6 × 2 ) = - 18 + 12 = -6 → Correct
(5 × - 3 ) + 2 = - 15 + 2 = - 13 → Correct
(- 3, 2 ) is a solution to the system
