Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...
The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units
Answer:
I think it's called a term.
Hope this helps :)
11/15-2/5
Multiply 2 and 5 to get a common denominator of 15
11/15-6/15
=4/15
Answer:
6Apples
Step-by-step explanation:
Number of apples required for the recipe = 1.2kilograms
But we know that 1000g = 1kg
So;
1.2 kg will give:
1.2 x 1000 = 1200kg
Average mass of the apple = 200g
So;
The number of apples used = 
= 6Apples
<span>We know that the cost of 5 kg of peanuts is $4.50, then the unit price per kilogram is
$4.50/5 kg = 0.90 $/kg
And the unit price per gram is:
$0.90 / kg * 1 kg/1000 = 0.0009 $/g or 0.09 cents/gram</span>
