Answer:

80, 40, 40

Step-by-step explanation:

The rule is if the number before the tens place is 5 or more round up and if it is 4 or less round down.

I like to look at it without the rule and what makes sense.

82.14:  my choices are 80 or 90.  What number is 82.14 closer to on the number line?  80.

38.5  The choices are 30 and 40.  This number on a number line would be closer to 40

41.3  The choices are 40 and 50.  On a number line this number would be closer to 40.

The Research Triangle in North Carolina is formed by Raleigh, Durham, and Chapel Hill. Is this triangle a right triangle? Explai
ryzh [129]

The triangle is not a right triangle. This is because the sum of the square of the two shorter lengths is not equal to the square of the longest length.

<h3>Is the triangle a right triangle?</h3>

In order to determine if the triangle is a right triangle, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where a = length

b = base

c = hypotenuse

12 ² + 24²

= 144 + 576 = 720

29² = 841

Write an equation in standard form of the line that passes through the given point and has the given slope. (5,0) m=4/3
sveticcg [70]

\text{The standard form of a line:}\ Ax+By=C

\text{The point-slope form:}

y-y_1=m(x-x_1)

\text{We have the point (5, 0) and the slope}\ m=\dfrac{4}{3}

\text{substitute:}\\\\y-0=\dfrac{4}{3}(x-5)\qquad|\text{use distributive property}\\\\y=\dfrac{4}{3}x-\dfrac{20}{3}\qquad|\text{multiply both sides by 3}\\\\3y=4x-20\qquad|\text{subtract 4x from both sides}\\\\-4x+3y=-20\qquad|\text{change the signs}\\\\\boxed{4x-3y=20}
