I think if those three work together to make one gift box it should take them one hour. I would say this because three of them working together should cut it down by a good 2/3's. Ergo 1 hour. Have a good day
Answer:
Amount of material for chain link = 30 feet
Amount of material for rope = 50 feet
Step-by-step explanation:
Let the amount of chain link = X
The amount of rope be represented by Y
He bought a total of 80 feet of materials
Hence we have:
X + Y = 80 ....... Equation 1
Y = 80 - X
The chain-link cost two dollars per foot and the rope cost 1.50 per foot he spent a total of $135
X × $2 + Y × $1.50 = $135
2X + 1.5Y = 135 ......Equation 2
Substitute 80 - X for Y in Equation 2
2X + 1.5(80 - X) = 135
2X + 120 - 1.5X = 135
Collect like terms
2X - 1.5X = 135 - 120
0.5X = 15
X = 15/0.5
X = 30 feet
Substitute 30 feet for X in Equation 1
X + Y = 80 ....... Equation 1
30 + Y = 80
Y = 80 - 30
Y = 50 feet
Hence the amount of material he used for the chain link = 30 feet and the amount of material he used for the rope was = 50 feet
33 rounded to the tens place would be 30.
89 rounded to the tens place would be 90.
Answer:
The median is 1.5
The median is spread.
Step-by-step explanation:
0, 0, 1, 1, 1, 2, 2, 2, 2, 3
count from the outside to the middle, you have 2 and 1.
You then do (2+1) divided by 2, and that is your median.
The median is 1.5, it is SPREAD because there was no middle, there were 2 numbers that were needed in order to get the answer.
