Answer: Use the formula A=1/2bh. A is the area, B is the base, and H is the height. It is pretty straight forward from there.
Step-by-step explanation:
Answer:
A.30
Step-by-step explanation:
^ABC = 180⁰-60⁰=120⁰
=> 4x⁰=120⁰
=> x = 30⁰
Many solutions
Rearrange variables to the left side of the equation: x + 5y = 0 , 30y + 6x = 0
Reorder the equation:
x + 5y = 0
6x + 30y = 0
Multiply both sides of the equation by a coefficient:
{ 6(x + 5y ) = 0 x 6
{ 6x + 30y = 0
Apply the Distributive Property:
{ 6x + 30y = 0 x 6
{ 6x + 30y = 0
Apply Zero Property of Multiplication:
{ 6x + 30y = 0
{ 6x + 30y = 0
Subtract the two equations:
6x + 30y -(6x + 30y) = -0
Remove parentheses:
6x + 30y - 6x - 30y = 0
Cancel one variable: 0 = 0

Add total rolls:
The number of rolls is the height of each bar:
14 + 12 + 16 + 15 + 13 = 70
70 total rolls
The numbers greater than 3 are 4 and 5
4 was rolled 15 times and 5 was rolled 13 times
15 + 14 =28 Total times
The prInability of that happening would be 28/70 which reduces to 2/5
The answer as a fraction is 2/5 which is 40% as a percentage.
There really isn't any distributing done, as the perimeter is the total length of the shape, and since this is a rectangle it has two two equal sides, 7+7=14 and 13+13=26, 14+26=40 inches
