You have 56 marbles to share with your friends. If each friend gets exactly 4 marbles, which equation could you use to solve for
2 answers:
Answer:
4n = 56 is the equation
Step-by-step explanation:
You have 56 marbles to share with your friends.
Each friend gets exactly 4 marbles.
Let the number of friends be 'n'
The equation would be = 4
By cross multiplication
4n = 56 will be the equation required to get the value of n
n =
n = 14
number of friends are 14.

Answer:
115.48
Step-by-step explanation:
This shape can be split into two distinct shapes
Two halves of a semi circle, and a rectangle in between
Circle:
Putting both halves of the semi circle together will give you a full circle. The diameter of the circle is given (7m).
The area of a circle is A = π
The radius, r, is half of the diameter, so 7 / 2 = 3.5m
A = π
A = π *
A = 38.38
Rectangle:
The area of a rectangle is A = h b
The height, h, is known at 7m
The base, b, can be found by removing the length from the dot to the end of the semi circles. This length is the radius of the semi circles, 3.5m
Removing the radius from the total length given
18 - 3.5 - 3.5 = 11m
The base is 11m
A = h b
A = 7 * 11 = 77
Total Area = Circle area + Rectangle area
Total Area = 38.38 + 77 = 115.48
