The area of the base is:
A = root ((s-a) * (s-b) * (s-c) * (s))
Where,
a, b, c: sides of the triangle
s = (a + b + c) / 2
We have then:
s = (9 + 9 + 9) / 2
s = 13.5
A = root ((13.5-9) * (13.5-9) * (13.5-9) * (13.5))
A = 35.07
Then, the surface area of the prism is:
S.A = 2 * A + 9h + 9h + 9h
Where,
h: height of the prism:
Substituting values:
421.2 = 2 * (35.07) + 9h + 9h + 9h
Clearing h:
27h = (421.2 - 2 * (35.07))
h = (421.2 - 2 * (35.07)) / (27)
h = 13
Answer:
the height of the box is:
h = 13 inches
Answer:
Step-by-step explanation:
1.5x - 15 dollars = x - 20 Add 15 to both sides.
1.5x - 15 + 15 = x - 20 + 15
1.5x = x - 5 They will never coincide.
1.5x-x = - 5
0.5x = - 5 Multiply by 2
x = - 10

Answer:
$1.65
Step-by-step explanation:
If h is the price of a hot dog, then the total bill was ...
4(2h +1.25) = 18.20
2h +1.25 = 4.55 . . . . . . divide by 4
2h = 3.30 . . . . . . . . . . . subtract 1.25
h = 1.65 . . . . . . . . . . . . . divide by 2
The price of one hot dog was $1.65.
Answer:
This the answer but it words because i didn't really wanna type all those numbers but just transfer this into numbers and you'll have the simplified version :)
x to the 4 power minus 4x to the third power minus 2x squared plus 12x plus 9
