You are correct
12.2^2 x 3.14 x 6.1 = 2850.9
Answer:
The second choice.
Step-by-step explanation:
The length of AC must be equal to 5, since it is horizontally five units. We can rule out the first option.
Length BC cannot be the square root of 16, since that would be exactly 4 units. BC is slanted and does not represent a completely vertical line, so it is not a whole number. We can rule out the fourth option.
Length AB cannot be a whole number, being a slanted line that crosses a total of more than four units. Option three can be ruled out.
Therefore, we are left with the second option.
Answer:
y = x + 2
Step-by-step explanation:
As the equation of a line is in the form y = mx + c:
Step 1 - Calculate the y intercept
This can be done by looking at the y coordinate where x = 0:
y = mx + c
In the picture, the y intercept is 2 so:
y = mx + 2
Step 2 - Calculate the slope
This can be calculated by:
Get two sets of coordinates:
(0, 2) and (2, 4)
Calculate the changes by subtracting from one another:
So the gradient is 1, meaning the equation of the line is:

Answer:
$301.78
Step-by-step explanation:
395*0.3=118.5
395-118.5=277.50
277.50*0.0875=24.28125
24.28125+277.50=301.78125
301.78125 rounded is 301.78
Answer:
72 degrees
Step-by-step explanation:
To determine the value of DBC, we first have to determine the value of q
Angle on a straight line = 180 degrees
7q - 46 + 3q + 6 = 180
10q - 40 = 180
collect like terms
10q = 180 + 40
10q = 220
q = 22
Substitute for q in angle dbc
3(22) + 6 = 72 degrees
