The price of a mobile phone decreased from $375 to $250 during a clearance sale. What is the percent of decrease in the price?Round to the nearest percent, if necessary.

A.
32%

B.
33%

C.
50%

D.
83%

Answers

so decrease is 375-250=75

so convert 75/375 to percent
percent means part out of 100 so
x/100=x%

divide 125/375=0.3333/1

multiply by 100/100=33/100=33%

the answer is 33% or B

How do you change 36/10 to a decimal?

Answers

You do top ÷ bottom, so it is 36 ÷ 10.

36/10 it is like 36÷10 and then we just calculate it and it is 36÷10=3.6

Jacob wants to make a graph to show the relationship between temperatures in Fahrenheit and degrees Celsius. He plots the following points:(11, −11.7), (15, −9.4), (25, −3.9), (35, 1.7), (45, 7.2)

He uses the following steps to plot the graph:

1.Label origin as (0, 0)
2.On x-axis, label Temperature in Fahrenheit.
3.On y-axis, label Temperature in degrees Celsius.
4.The scale on x-axis starts from 0 and goes up to 700 at intervals of 20.
5.The scale on the y-axis starts from −12 and goes up to 12 at intervals of 2.

Which of the following best describes the graph?
A. It will not be spread out horizontally across the entire coordinate plane because in Step 4, Jacob selected an incorrect scale on the x-axis.
B. It will not be spread out vertically across the entire coordinate plane because in Step 5, Jacob selected an incorrect scale on the y-axis.
C. It will not be spread out horizontally across the entire coordinate plane because in Step 2, Jacob plotted Fahrenheit instead of Celsius on the x-axis.
D. It will not be spread out vertically across the entire coordinate plane because in Step 3, Jacob plotted Celsius instead of Fahrenheit on the y-axis.

Answers

The correct answer is option A.
The values of 'x' from the points he ploted are 11, 15, 25, 35, 45.
But he chose a scale on x-axis that starts from 0 to 700 which is far above the points he wants to plot.
Hence, the graph will only stop at x = 45 and other points from 46 to 700 will not be covered by the graph.

Answer:

The correct answer is option A.

Step-by-step explanation:

If x= -3 and y= -2, find z when z = 2x y^2
