#1) Mrs. Ebanks planted two trees on a
uranmaximum [27]

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 :

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4

Now using distance formula,

D=\sqrt{(12-0)^2+(4-8)^2}\\\\=\sqrt{144+16} \\\\=12.64\ m

So, the distance between the two trees is 12.64 m.

If cheese is $4.40 per kilogramme, what should I pay for 200 grammes?
Verizon [17]
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

Gnesinka [82]
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78

What is the area of the trapezoid shown below?​
Olin [163]

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
