Answer:
DBC = 75
Step-by-step explanation:
ABD and DBC are supplementary angles. They add to 180 degrees.
ABD + DBC = 180
105 + DBC = 180
Subtract 105 from each side
105-105 + DBC = 180-105
DBC = 75
Answer:
<u>The width is 1.67 or 1 2/3 feet approximately</u>
Step-by-step explanation:
Area of the dog pen = 14 1/5 = 14.2 square feet
Length of the pen = 8 1/2 = 8.5 feet
Width of the pen = x
Let's recall that the formula of the area of a rectangle is:
Area = Length * Width
Replacing with the values we know:
14 1/5 = 8 1/2 * Width
14.2 = 8.5 * Width
Width = 14.2/8.5
Width = 1.67 feet (rounding to the next hundredth)
1.67 ≅ 1 2/3
<u>The width is 1.67 or 1 2/3 feet approximately</u>
Answer: The answer would be 3.91666666667
Surface area is the area that is on the outside of a figure and will be used when you have to cover something, but a volume is an area inside an object and is used in finding the amount someone can hold within something else.
Answer:
y = x -3
Step-by-step explanation:
From the graph we see the line goes from point (0, -3) to point ( 3, 0), so we can find the slope as m= rise ( go up 3) / run ( go to the right 3) = 3/ 3 = 1
From the graph we can also see the y-intercept ( where the line intersects the y axis is at b = -3
The general equation of the line is y= mx+ b
Our line's equation is y = x -3, because m=1 and b= -3
