Answer: 50 cups of coffee
Step-by-step explanation:
Let x represent the number of cups of coffee that it will take for the cost at Dunkin Donuts to be the same as having a Keurig and k-cups.
He orders a coffee from Dunkin Donuts and it costs him $3.50 everyday. It means that the cost of ordering x cups would be 3.5x.
The Keurig is $150 and each k-cup costs $0.50. It means that the cost of ordering x cups would be 150 + 0.5x.
For the ordering cost to be the same, it means that
3.5x = 150 + 0.5x
3.5x - 0.5x = 150
3x = 150
x = 150/3
x = 50

Step-by-step explanation:
Answer: -1 1/8
Step-by-step explanation: When you have a problem like this, you have to divide.
So you turn the improper fraction into a mixed number which (4 1/2 turns into 9/2) and then you do KCF (Keep Change Flip). So you keep the 9/8, change division into multiplication, and since we are going to put the four over a 1 like this 4/1, we need to change it into 1/4. Then you multiply across. 9x1=9 and 2x4=8 so it would be 9/8. But it's an improper fraction right? So you do long division, and you get -1 1/8.
-103
if he lost the same weight each week that means -412 (the weight he lost) ÷ 4 (number of weeks) = -103 (amount of weight lost in one week)
Answer:
Step-by-step explanation:
If the bars will be packed in cartons which are 1 foot wide, 1 foot high, and 1 foot long, the volume of the carton will be expressed as shown;
Volume of carton = Length * Breadth * Height
Volume of carton = 1ft*1ft*1ft
= 1ft³
Given the dimension of shipping crate to be 5 ft long, 12 ft wide, and 4 ft high, the volume of the tank will be 5*12*4 = 240ft³
Number of cartons they pack into the shipping crate = Volume of the shipping crate/volume of one carton
Number of cartons they pack into the shipping crate = 240ft³/1ft³
= 240 cartons
Answer:
number of cartons that can be packed in the shipping crate = 240 cartons
Step-by-step explanation:
The cartons are cube since the face all have the same dimension . The length = 1 ft, width = 1 ft and height = 1 ft.
The shipping crate is a rectangular prism or cuboid . The dimension is given as follows.
length = 5 ft
width = 12 ft
height = 4 ft
The number of the cartons that can be packed in the shipping crate can be calculated as follows.
volume of the cubed carton = L³
where
L = length
volume of the cubed carton = 1³ = 1 ft³
Volume of the shipping crate = LWH
where
L = length
W = width
H = height
Volume of the shipping crate = 5 × 12 × 4
Volume of the shipping crate = 240 ft³
number of cartons that can be packed in the shipping crate = 240/1 = 240 cartons
