Answer:
Correct option: c)
radius = 6 inches
Step-by-step explanation:
The complete arc of a circumference has 360 degrees, and the length is 2*pi*radius
Knowing this, we can use a rule of three to solve this problem:
144 degrees - > 15 inches
360 degrees -> 2 * pi * radius
144/360 = 15/(2pi*radius)
2pi*radius = 360 * 15 / 144
radius = 37.5/(2pi)
radius = 5.9683 inches
Rounding to nearest whole number, we have radius = 6 inches
Correct option: c)
It is multiplying by negative 3 each time. So the next numbers will be positive, negative, positive. The numbers would be this... 81, -243, and then 729 in that order:) Hope I helped!
Answer:
Answer:
Total number of cards = 32(4) or y=32(4)
Roberto had 128 cards.
Step-by-step explanation:
Consider the provided information.
Part (A)
He gave his four friends 32 baseball cards each.
Let the number of cards he have before giving them to his friends is y.
This can be written as:
y = 32(4)
Part (B)
Now solve the above equation as shown.
y = 32(4)
Multiply 32 with 4
y = 128
Hence, Roberto had 128 cards.
