Answer:
Step-by-step explanation:
EC = 12÷2 = 6
ED = √(CD² - EC²) = √(16² - 6²) = √220 = 2√55 ≅ 14.8 units
Answer:
B = (-7,10)
Step-by-step explanation:
Given that , a line AB has midpoint (-2,4) and the coordinates of A is ( 3 , -2). We need to find out the coordinates of B .
- Let coordinate of B be ( p,q ). We can use midpoint formula , as ,
=> Midpoint = ( x₁ + x₂ / 2 , y₁ + y₂/2 )
=> ( -2,4 ) = ( p + 3)/2 , ( q -2 )/2
=> -2 = p + 3/2
=> p + 3 = -4
=> p = -3 - 4
=> p = (-7)
<u>Also </u><u>:</u><u>-</u><u> </u>
=> q - 2/2 = 4
=> q -2 = 8
=> q = 8 + 2
=> q = 10
<h3>
<u>Hence</u><u> the</u><u> </u><u>coordinates</u><u> </u><u>of </u><u>B </u><u>is</u><u> </u><u>(</u><u> </u><u>-</u><u>7</u><u>,</u><u>1</u><u>0</u><u> </u><u>)</u><u> </u><u>.</u></h3>
It could be D but mathematically it's 3/6=1/2
Answer:
Step-by-step explanation:
- Distance = 20 km
- Water consumed = 334 quarts
<u>Water consumption rate is:</u>
- 334 quarts / 20 km = 16.7 quarts/km
20/100 is equivalent to 1/5.
Just divide by 20 on the top and bottom. (20/20)/(100/20)=1/5.
