Answer:
w = 62m
Step-by-step explanation:
We need to make an expression for the numbers of words (w) John types in m minutes.
We know he types 62 words in 1 minute, so 62 is the coefficient of m.
The dependent variable here is w, so that should on the left of the equal sign.
m, on the other hand, is independent, so that's on the right of the equal sign.
So, the expression is w = 62m.
Answer:
always try to draw a diagram first
Step-by-step explanation:
Jana ran The first 3.5 miles in 1/3 of an hour. remember the problem tells us that we want our answer in miles per hour or mph. so we have to set up our problem so that our units match in the end. The diagram above shows 3.5 mi over 1/3 hour. so we must divide 3.5 miles by 1/3 hour

therefore
Answer:
To make the cup 64.57 square inches of plastic were used.
Step-by-step explanation:
A cup has the format of a cylinder with a open top. The surface area of the cup is given by the area of it's base (a circle) and the area of it's walls, wich can be seen as rectangle where the width is the length of the circle at the base and the height is the height of the cylinder. So we have:
area of the base = pi*r^2 = 3.14*(1.75)^2 = 3.14*3.0625 = 9.616 square inches
area of the walls = 2*pi*r*h = 2*3.14*(1.75)*5 = 54.95 square inches
surface area of the cup = area of the base + area of the walls = 9.616 + 54.95
surface area of the cup = 64.57 square inches
To make the cup 64.57 square inches of plastic were used.
Answer:
A) The graph of g(x) is shrunk vertically by a factor of 1/9
Step-by-step explanation:
The given graph g(x) = 1/9√x
f(x) = √x
The altitude of g(x) = 1/9
The altitude of f(X) = 1
When comparing the graph of g(x) with f(x), the graph of g(x) shrunk by 1/9 because of the altitude.
Here with I have attached the graph.
Therefore, answer: A) The graph of g(x) is shrunk vertically by a factor of 1/9
Thank you.
