Answer:

because 3x10=300

Answer:

300 x 1/10 = 30 and 30 divided by 1/10 is 300

Step-by-step explanation:

You know 30 is 1/10 of 300 because 300 times 1/10 is 30

300*\frac{1}{10} = \frac{300}{10} =30

^Here you multiply 300 times 1/10, meaning 300/1 times 1/10, and so you multiply the numerator times the numerator and the denominator times the denominator...

Also, if you divide 30 times 1/10 (0.1) it will equal 300.

a line is perpendicular to y = 3/7x - 2 and intersects the point (3,3). What is the equation of this perpendicular line?
snow_lady [41]

Answer:

y = -7/3x + 10

Step-by-step explanation:

Step 1: Find the slope of the perpendicular line

Do this by taking the negative inverse of the first line

m = -7/3

Step 2: Find <em>b</em>

y = mx + b

y = -7/3x + b

3 = -7/3(3) + b

3 = -7 + b

b = 10

You should get y = -7/3x + 10 as your final answer.

This math I just can't figure out
Elena-2011 [213]

Step-by-step explanation:

Here's the first question and how to solve the second.

So the first business start with 250, that's your b in slope.

y = mx + b

y = mx + 250

Now, they charge 14 an hour so that's your m.

y = 14x + 250

x is the number of hours it takes.

The second business is straight up 22 per hour, so it's just y = mx, where b is 0.

y = 22x VS y = 14x + 250

Try plugging in different numbers and seeing how much it take to level out!
