Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :

We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,

So, the distance between the two trees is 12.64 m.
1 kg is 1,000 grams.
200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.
Thus 200 g= 1/5 kg = 0.2 kg.
1 kg of cheese is $4.40,
so 0.2 kg of cheese is 0.2kg x $4.40/1kg=4.40 x 0.2 $= 0.88$
Answer: $0.88
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
That’s all correct thanks
Answer:
78 sqr units
Step-by-step explanation:
Use the Pythagorean Theorem to help find the base opposite the two.
The base of the second parallel line is sqrt( (15^2) - (12^2) ) = sqrt(81) = 9
The second base = 9 + 2 = 11
Area = (b1 + b2)*h/2
h = 12
b1 = 2
b2 = 11
h = 12
Area = (11 + 2)*12/2
Area = 13 * 12/2
Area = 78 square units
