Write and solve a proportion to answer the question. 3/4 is 60% of what number?

Mathematics
1 answer:
Ganezh [65]3 years ago
6 0


3/4 equals .75, and 60% equals .60. Therefore, we can set up an equation. .75=.60x, where x is the number we are looking for.

Divide each side by .60 to get the variable by itself. .75/.60= 1.25.


Hope this helped!!! :)

Steps to finding the line in the diagram with the format 'ax + by = c

1. Find the slope

  • To find the slope, we need any two points on the line --> (0,4) and (3,0)

                  Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}

2. Set up, with any one point on the line and the slope, in point-slope form

   

        (y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4

<u>Answer</u>: \frac{4}{3}x+y = 4

Hope that helps!

The formula for area is pi x r^2 (pi times radius squared) so, for number 7 youre given the radius or "r", which is half the length of the inside of the cirlce. On a calculator: you would do 8 times 8 (8^2) because that's the radius squared and then you should get 64 and times 64 by 3.14 or use the pi button depending on what your teacher prefers you to use. 

When you're given diameter or "d" which represents the is equal to the radius times 2. So, for example, number 8 the diameter is 26 so, the radius is 13. Use the formula for area just like in number 7 to find the area of this circle. 

Make sure you pay attention to what information youre given (whether its "d", Diameter, "r" or radius. Use those two lists of steps for solving numbers 7 through 12. 

For numbers 13-15:
use the number (22/7) instead of 3.14 or the pi button on your calculator and do the same steps!!!!!

Let me know if you still need help after this:) happy math solving!
