Why would 6% as a fraction be 6/100?
dangina [55]
Well, percent (%) means per hundred, and your number is 6. Therefore, you have 6 per hundred, or 6/100. Also, when you have a percent and want to convert it into a fraction, you must divide the percent by 100, so you could just put the six over 100 since the line between the numerator and denominator basically means division.

What is the equation of the circle whose center and radius are given.
muminat
Hello!

The equation for a circle is

(x - h)^{2}  + ( y - k)^{2} =  r^{2}

(h,k) is the center
r is the radius

Put in the values you know

(x - 7)^{2} + ( y + 3)^{2} = 7^{2}

Simplify

(x - 7)^{2} + ( y + 3)^{2} = 49

The equation is (x - 7)^{2} + ( y + 3)^{2} = 49

Hope this helps!

4. In one semester, Doug and Laura spent a combined 230 hours in the tutoring lab. If Doug
IRISSAK [1]

Answer:

80 hours

Step-by-step explanation:

let d represent doug, let l represent laura

first, set up a system of equations representing the problem:

since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:

l=2d+10

d+l=230

then solve:

*first i rearranged the equations so i can solve this system of equations using elimination method*

l-2d=10

l+d=230

*subtract*

3d=240

d=80

so, doug spent 80 hours in the lab
