Answer:
D. No, the should have canceled out in step 4 making the correct answer 5.5mm.
Step-by-step explanation:
All the steps that Arden took were correct up until the last step:
1. V = Bh ⇒ 88 = *4^2 * h = 16
2. Divide by 16 from both sides: h = 88 / 16 = 88/16 = 5.5
Arden forgot to cancel out the pi from both the numerator and denominator, so her answer should have been 5.5 mm, not 5.5 mm.
Thus, the answer is D.
Hope this helps!
Answer:
radius of semi circle is 16mm.
diameter of semi circle is 32mm.
perimeter of triangle=sum of all sides.
perimeter of triangle = 20mm+20mm+32mm
perimeter of triangle =72mm
perimeter of semi circle=pi×r
perimeter of semicircle = 3.14×16mm
perimeter of semicircle =50.24mm
perimeter of the figure= 72mm+50.24mm=122.24mm
If you do 220-40 then the second digit of the negative number will equal x.
Step-by-step explanation:
First thing you need to do is Slope - intercept form of the line going through point A and B.
Slope-intercept form: y = mx + b (m = slope, b = y-intercept)
To get slope:
Lets set point A as point1 (x1, y1) and point B as point2(x2, y2).
x1 = -4
x2 = 8
y1 = 6
y2 = 3
If you plug these numbers in the slope equations:
=
m =
So a parallel line is a line that has a different b value but the same slope value.
To get b for the parallel line : we need to substitute the x and y for a given point (0,-2).
which will make -2 = 0( ) + b
now we solve for b:
-2 = 0 +b
b = -2
So the whole Slope-intercept form of the parallel line is: y = x -2
