Answer:
3
Step-by-step explanation:
-5y + 4 = -11 Get rid of the numbers to get y alone.
-5y +4 minus 4 = -11 minus 4 Here you are removing the 4 from the left
-5y = -15 Now you will have to get rid of the -5
-5y/(-5) = -15/(-5)
y = 3
A) number of outcomes * number of outcomes =9*9=81
possible outcomes 123456789 for 1 digit
b)number of outcomes(even) * number of outcomes(even) =4*4=16
possible outcomes even 2468
Circumference is found with the formula
c = pi × d
d is diameter and we will use 3.14 for pi.
The diameter is the measure across the center of the circle. In the first problem, you are given the radius, so we have to multiply by 2 to get the diameter. Then we can use the formula.
12.4 in × 2 = 24.8 in (that's the diameter)
c = pi × D
c = 3.14 × 24.8
c = 77.872 inches
circumference is 77.872 inches.
Try the other problems on your own. They are just like this one. Just make sure they are giving you the diameter and not the radius. Post if you have problems.
