Answer:
Approximate weight of cell phone is between 100 gm to 200 gm.
1 Pound = 0.45359237 Kilograms
= 0.4545 kg
2.8 pound = 2.8 × 0.4545
= 1.2727 Kg
It is given that weight of cell phone is pounds, means
Kilograms.
Which is equal to, grams.
Because, 1 Kilogram = 1,000 gram
If, n=0
Weight of cell phone = 1272.7 grams=1.2727 Kg
when, n=1
Weight of cell phone = 12727 grams=12.727 Kg
n= -2,
Weight of cell phone = 12.727 grams
n=- 3
Weight of cell phone = 1.2727 grams
None, of the weights are appropriate weight of cell phone.Neither of four options provided here is true.

Answer:
some information is missing, so I looked for similar questions and found the attached image:
since each recipe requires ¹/₂ cup of butter, you are able to make 12 ÷ ¹/₂ = 24 recipes with one container of butter (assuming you have all the other ingredients).
One-half, ¹/₂, is a fraction that can also be written in decimal form as 0.5. Two times ¹/₂ is equal to 1, and similarly, twenty four times ¹/₂ is equal to 12.
The volume of the cone of radius 5 units and height 3 units is 78 cubic units.
Given radius of cone 5 units and height of cone be 3 units.
We are required to find the volume of cone.
Volume is the amount of substance that a container can hold in its capacity.
Formula of cone is 1/3 *π in which r is radius and h is height of cone.
We have to just put the values in formula.
Volume=1/3 *π
=25*3π/3
=75π/3
=25π
Put π=3.14 as said in the question.
=25*3.14
=78.5 cubic units.
After rounding we will get 78.
Hence the volume of cone whose radius is 5 units and height is 3 units is to be 78 cubic units.

Question is incomplete as it should include the figure.
Answer:
y = -4x + 1
Step-by-step explanation:
The line passes through points (-5,21) and (-4,15)
Slope(m) = change in y ÷ change in x
m =
m = = -36/9 = -4
Taking another point (x,y) on the line and comparing it with point (4,-15):
-4 =
Cross multiplying gives:
y + 15 = -4x + 16
y = -4x + 1
