When you are going from a larger measurement (such as meter) to a smaller measurement (such as centimeter), you will have to multiply by units of ten. Specifically if you are going from m to cm, you will use (n x 10^2) with n being the given number for meters. When you are going from a smaller measurement (such as centimeter) to a larger measurement (such as meter), you will have to divide by units of ten. Specifically if you are going from cm to m, you will use (n / 10^2) with n being the given number for centimeters.

Answer:

884. D

885. C ( changed my answer)

886. B

887.A

For number 844, the diameter if the fan is 12 inches. To find Circumference, multiply the radius by two and then pi. The radius of the fan is 6, multiplied by 2 is 12, and multiplied by pi gives 12 times pi.

885 says half of the area gives the circumference. So we can write a formula, (pi*r^2)/2=2*pi*r. If the radius were 4, this would make the equation true. So the answer is 4.

886. Circumference=2*pi*r

r=6.78

2*pi*6.78

13.56*pi

887.

3*3=9

13-3=10

10*23=230

230+9=239 units squared

I need help with 16a and 17. i haven't been able to understand this in class and no one was able to help me

kompoz [17]

16a. 21cm. bc when it has 10 grams it moves half of that to 5cm so divide 42 by 2 and you get 21cm

17. remember y=mx+b; m is slope and b is y-intercept
you have to put your equation from point slope to y=mx+b
4x+y=6
subtract 4x from each side
y=-4x+6
slope = -4
y-intercept= 6

hope this helped :)
