Answer: The correct answer is option (A) 60,000 ft.
Step-by-step Explanation: In a triangle with all three sides given and no vertical height, we shall not apply the conventional (commonly used) formulae which is
Area = 1/2 B x H
Rather we shall apply the Heron’s Formulae which states as follows;
Area = [square root] s(s - a)(s - b)(s - b)
Where a, b and c are the three sides and a is the semi-perimeter.
We shall start with the semi-perimeter which is
s = (300 + 400 + 500)/2
s = 1200/2
s = 600
Therefore applying the Heron’s formula, the area is calculated as
A = [square root] 600(600 - 500)(600 - 400)(600 - 300)
A = [square root] 600 (100)(200)(300)
A = [square root] 3600000000
A = 60000
The area of the given triangle is 60,000 ft.
Volume= length*width*height = Area * height
<span>square region: A= 32^2= 1024 </span>
<span>circle region: A= pi*radius^2= pi*(diameter/2)^2= 15^2 pi= 225pi </span>
<span>rectangle region: A= 30*45= 1350 </span>
<span>Volume= (1024+ 1350 +225pi) *6 = 14,244 +1350pi </span>
<span>The units are ft^3 </span>
<span>1 yard = 3 feet </span>
<span>yard^3= 27 ft^3 </span>
<span>ft^3= 1/(27y^3) </span>
<span>Cost = price / unit *Volume +surcharge </span>
<span>Cost= 12.50/y^3 *(14,244 +1350pi)ft^3 +25 </span>
<span>= 12.50/27 *(14,244 +1350pi) +25 </span>

Answer:
it 480
Step-by-step explanation:
if your k 12 this is right
Answer:
2/3
Step-by-step explanation:
when multyplying a fraction and a whole number, its better if you put the whole number over 1 to make it a fraction, now you can multiply fractions easier, just multipl accross, 2*3 is 6, 9*1 is 9, now you have a fraction of 6/9 which can be simplified to 2/3
