Is a tray with a circumference of 32 inches is big enough to
yKpoI14uk [10]

Answer:

Yes

Step-by-step explanation:

Circumference formula is C=2 pi r, if you divide the pizza by 2 to get the radius,5, then input it into the formula to get 31.41592654, and since this number is smaller than 32 it will fit. If 10 is the radius it will not fit.

Identify the solution and graph of the given inequality. 34 > 3(2 − x)
zloy xaker [14]

Answer:

x > 28/3

Step-by-step explanation:

34 > 3(2 − x)

simplify the bracket

34 > 6 -3x

combine the like terms

34 - 6 > 3x

28 > 3x

divide by 3

x > 28/3

Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.

It is in slope intercept form; y = mx + b

where mx is the slope and b is the y-intercept;

x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times

And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.

Hope this helps!

Good luck.
