The first thing we should know is the area of the triangular base.
Triangular base area:
A1 = root (s * (s-a) * (s-b) * (s-c))
Where, s is the semi-meter of the triangle:
s = (a + b + c) / 2
a, b, c: sides of the triangle.
Substituting:
s = (2 + 3 + 4) /2=4.5
A1 = root (4.5 * (4.5-2) * (4.5-3) * (4.5-4))
A1 = 2.90
Then, you must know the area of each rectangle associated with each side of the triangular base.
Rectangle area 1:
Ar1 = (a) * (l)
Ar1 = (2) * (7)
Ar1 = 14
Rectangular area 2:
Ar2 = (b) * (l)
Ar2 = (3) * (7)
Ar2 = 21
Rectangular area 3:
Ar3 = (a) * (l)
Ar3 = (4) * (7)
Ar3 = 28
Finally the surface area is:
A = Ar1 + Ar2 + Ar3 + 2 * A1
A = (14) + (21) + (28) + 2 * (2.90)
A = 68.8 in ^ 2
answer:
<span> the surface area of the box of chocolates is
</span> A = 68.8 in ^ 2
Answer:
its the last answer my boi
Step-by-step explanation:
my big brain
nah i just took the test lol
Treat as an equality, except flip the sign direction when yo multiply or divide both sides by a negative number
first distribute
2(4+2x)<u>></u>5x+5
distribute
8+4x<u>></u>5x+5
minus 4x fro both sides
8<u>></u>x+5
minus 5 from both sides
3<u>></u>x
x<u><</u>3
x is less than or equal to 3
I believe 75% because 2 of 8 kittens would be 25% are male.
Empty set is a set with no element (the number of elements in the empty set is zero).
A set is subset set of another set B if it its elements belong also to subset B.
Because an empty set has no element its elements (there are none) belong to any set B. So the empty set is a subset of any set.
Example: Set A:The set of all people who can fly Set B:The set of all people.
There are no elements in the set A (no one has wings to fly), so set A is a subset of Set B.
