Step-by-step explanation:

Which type of graph would allow us to quickly see how many months between 100 and 200 students were treated?

Histogram is a type of graph where bars of different heights are used to show continuous data. The difference between the intervals is called class marks.

So, here the best graph can be histogram as it will properly show the intervals.

Michelle and Cody have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Mic

Dennis_Churaev [7]

Answer:

Step-by-step explanation:

Let x represent the certain number of of subscriptions in an hour that each of them would sell so that they will end up earning the same amount.

Michelle earns a base wage of $8 per hour, as well as $1 for every subscription that she sells. This means that the total cost of selling x subscriptions in an would be

x + 8

Cody gets $3 per subscription sold, in addition to a base wage of $4 per hour. This means that the total cost of selling x subscriptions in an hour would be

3x + 4

For both of them to earn the same amount,

x + 8 = 3x + 4

3x - x = 8 - 4

2x = 4

x = 4/2 = 2

They would earn the same amount when they sell 2 subscriptions.

The amount that each would earn is

2 + 8 = $10

Alla [95]

Answer: (a) Magnetic flux before rotation is 7.2 × 10^-8 Wb and magnetic flux after rotation is 0

(b) The average emf induced in the coil is 3.6×10^-4 V

Step-by-step explanation:

Here is the complete question:

In a physics laboratory experiment, a coil with 200 turns en-closing an area of 12 cm2 is rotated in 0.040 s from a position where its plane is perpendicular to the earth’s magnetic field to a position where its plane is parallel to the field. The earth’s magnetic field at the lab location is 6.0×10^−5T. (a) What is the total magnetic flux through the coil before it is rotated? After it is rotated? (b) What is the average emf induced in the coil?

Flour costs $0.80 per pound and sugar costs $0.50 per pound. An order of flour and sugar weighs 15 pounds and costs $9.00. Make

LenaWriter [7]

Answer: $x+y=15$

$0.80x+0.50y=9$

Step-by-step explanation:

Let x be the amount of flour and y be the amount of sugar ordered.

Since, the order of flour and sugar weighs 15 pounds.

Therefore, $x+y=15$

Also, Flour costs $0.80 per pound and sugar costs $0.50 per pound.

The cost of ordered flour=$0.80x

The cost of ordered sugar=$0.50y

Now, the total cost of the order= $0.80x+0.50y=9$

Hence, for the given situation the system of equations is:-

$x+y=15$

$0.80x+0.50y=9$
