Answer:

30 is 20% of 150 i.e. 20% of total 150 students in the marching bank play the trumpet.

Step-by-step explanation:

Draw two number lines:

  1. One number line to represent number of students from 0 to 150. For convenience, divide the number line into intervals of 15 so that 30 is also present on the line.
  2. Second number line to represent percentage and divide it in intervals from 1 to 100.

Now, place the other number line just below the other number line and draw a vertical line as shown the attached figure.

We find out that 30 is at 20% of 150.

It means that 20% (30 of total 150) of total 150 students in the marching band, play trumpet.

Answer:

y=-6/5x - 1

Step-by-step explanation:

Slope intercept form is y=mx+b so first lets get it into correct order by subtracting the 6x to the other side.

6x-6x+5y=-5-6x

This gives you

5y=-6x-5

Now you need to isolate the y since the 5 is being multiplied by the variable "y" we need to divide to to separate. Divide all terms by 5.

5y/5=-6/5x+(-5)/5

This gives you your final answer:

y=-6/5x - 1

Can I get some help? Thanks!

Answer:

The answer would be b.

Step-by-step explanation:

We can easily use process of elimination here. a would not be correct because it's saying that as you move forward, you increase when it's the total opposite. You are decreasing as you move forward.

C and D would not be correct because they both are talking about 0 temperature, and there is no data for that temperature.

So B is the correct answer.

How can i do scientific notifacation please
Ainat [17]
Do you mean scientific notation?

If so,
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

In order to write a number in scientific notation, I suggest you place the tip of your pencil right after the last digit in the number.
Then go backwards, counting each jump to the next number (this will be your exponent number).
You will go backwards until you reach your first NON-ZERO digit, which is where you will place the decimal point.

Multiply the decimal you now have by 10 (multiplying by 10 applies every time!) and then to the power of however many spaces you went back.
