8, 20 and 6
Step-by-step explanation:
A coefficient is the numerical part of an algebraic term. Example: in the term 2x the coefficient is 2.
Can write 3x or 3(x) or 3•x
6. Answer:
72.84
Step-by-step explanation:
To find the perimeter of the rectangle, just add the sides together except the one connected to the semicircle
12 + 15 + 15 = 42
The diameter of the semi circle is 12
πr + d = 6 * π + 12 ≈ 30.84
Add them together
42 + 30.85 = 72.84
7. Answer:
78.54
(78.5)
Step-by-step explanation:
The shape is a circle
Radius is 5
Diameter is 10 (diameter is always double of the radius)
π * r^2 = π * 25 cm^2 = 78.54 cm^2
8. Answer:
50.27
Step-by-step explanation:
The shape is a circle
Radius is 4
Diameter is 8 (diameter is always double of the radius)
π * r^2 = π * 16 ft^2 = 50.27 ft^2
(16 = 8 * 2)
Answer:
Step-by-step explanation:
Problem 4a
You have 6 numbers on the cube, a bag with 4 letters and a spinner with 3 letters
The total number of results is
6 * 4 * 3 = 72
Problem 4b
P(A,3,Q) = (1/3)(1/6)(1/4) = 1/72
Problem 4c
A and Q remain the same. 1/3 and 1/4
Not rolling a 6 is a little different. Success will result in a 1 2 3 4 5 being thrown. That's 5/6
So the results are 1/3 * 1/4 * 5/6 = 5/72
