Answer:
The perimeter of triangle ΔABC is approximately;
(A) 20.0
Step-by-step explanation:
In ΔABC, the coordinates of the vertices are given as follows;
A(-4, 1), B(-2, 3), C(3, -4)
The length, 'l', of the sides of the triangle with known 'x', am]nd 'y' coordinates are given as follows;
Therefore, we have;
The length of segment = √((3 - 1)² + (-2 - (-4))²) = 2·√2 ≈ 2.83
The length of segment = √(((-4) - 3)² + (3 - (-2))²) = √74 ≈ 8.6
The length of segment = √(((-4) - 1)² + (3 - (-4))²) = √74 ≈ 8.6
The perimeter of a geometric shape is equal to the sum of the length of sides of the figure
The perimeter of triangle ΔABC = (The length of segment ) + (The length of segment ) + (The length of segment )
∴ The perimeter of triangle ΔABC = 2·√2 + √74 + √74 ≈ 20.0.
You basically simplify for this one,18 / ? = 9
18/2=9
So in this case, 8*2 is 16! Hope this helps!
Answer:
The answer is C
Step-by-step explanation:
<em><u>Answer</u></em>
In order to use the distributive property I first get the amount of the water fell in ;
<u>One </u><u>year</u>
1.68mm
<u>A </u><u>half</u><u> </u><u>a </u><u>year</u>
½× 1.68mm
= 0.84mm
<u>One </u><u>and </u><u>a </u><u>half </u><u>years (</u><u>Using </u><u>the</u><u> </u><u>distributive</u><u> </u><u>property</u><u>)</u>
1.68mm + 0.84mm
<u>1</u><u>6</u><u>8</u><u>m</u><u>m</u> + <u>8</u><u>4</u><u>m</u><u>m</u>
100. 100
(168÷100) + (84÷100)
(168+84) ÷ 100
252 ÷ 100
<u>2</u><u>5</u><u>2</u>
100
= 2.52mm
Therefore the variation in the water level in the time period was 2.25mm
