Answer:
0.64
Step-by-step explanation:
Find the number in the hundredth place 4 and look one place to the right for the rounding digit 1
. Round up if this number is greater than or equal to 5 and round down if it is less than 5
.
Split the figure into 3 shapes: a trapezoid,a rectangle and a triangle
Area of trapezoid
A= 1/2(b1+b2) h
A = 1/2(3 +9)(8)
A = 1/2(12)(8)
A = 48 square units
Area of rectangle:
A = L x W
A = 9 x 8
A = 72 square units
Area of triangle
A = 1/2bh
A = 1/2(3)(8)
A = 12 square units
Area of figure = 48 square units + 72 square units + 12 square units
= 132 square units
Answer
132 square units
Answer:
-59
Step-by-step explanation:
x+41=-18
x= -18-41
x = -59
Answer:
slope of AB = 2
slope CD = 2
Step-by-step explanation:
the equation of a line is y = ax+ b where a is the slope, b is the y-intercept
let us take yB - yA
→ yB - yA = axB <u>+ b</u> - axA <u>- b</u>
→ yB - yA = a(xB - xA)
→ a = (yB - yA) / (xB = xA) = (6 - 2) / (-5 - (-7)) = 2
same goes for line CD
B.) y=3x
The slope of a given line is defined by <em>y=mx+b</em>, where b is the y-intercept (the point at which the line crosses the y-axis) and m is the slope (rise/run). We see that the y-intercept is 0 (because the line hits the y-axis at 0) and the slope is 3 (rise=3 and run=1, so 3/1=3).
