302400. the amount of seconds in a week divided by 2
Slope intercept form is the form of y=mx+b. Your m is the slope, and the b is your starting point. To find this, you can start at the bottom, and go to the next point it passes through. It is alway rise over run. Rise is your y, x is your run, so it is always y/x. If you need help finding the slope, use the slope formual, which is y₂-y¹/x₂-x₁. You can use any of the points on here to get your slope... As for the B, well... I can't really help you on that. Sorry! But I hope this helps! :)
40 boys and 68 girls
let's start with variables and an equation.
boys: x
girls: 2x - 12
and we know that boys and girls make up the class. so let's add the two expressions.
x + 2x - 12 = 108
3x - 12 = 108
+ 12 + 12
3x = 120
x = 40 boys
BUT x is only the number of BOYS in the class. so we have to find girls now. let's plug in our value of x into the girls' equation.
2x - 12 = # of girls
2(40) -12 = # of girls
80 - 12 = # of girls
68 girls
let's check our answer!
68 + 40 does in fact add to 108, therefore our answer is correct.
Answer:
Step-by-step explanation:
This is right triangle trig. The side opposite the x is 8, and the side adjacent to the x is 5. The tangent ratio uses those sides. We need to find what angle has a tangent of 8/5. To do this, make sure your calculator is in degree mode. Then hit "2nd" then tan and you will see tan with a little -1 and a parenthesis. Enter 8/5 and hit "enter" and you will get an angle measure of 57.9946. Rounded to the nearest degree this is 58 degrees. That's your answer!
