Since a cube is l x w x h, find the length of one side first:
∛8,000 = 20
The length of one side is 20 feet. This can represented as "s".
To find the area of one of the faces, use s²:
20² or 20 x 20 = 400
The area of one face is 400 ft²!
Answer:
2.6Kg
Step-by-step explanation:
Let the weight of apples be x and that of pears be y .
The farmer sold 7.1 kg of apples and pears .
4.5 of the 7.1kg is apples
That’s
x + y = 7.1kg
4.5kg + y = 7.1kg
Subtract 4.5kg from both sides
4.5kg - 4.5kg + y = 7.1kg - 4.5kg
y = 2.6 kg
The farmer sold 2.6kg of pears at the market
Answer:
y=-7; x=3
Step-by-step explanation:
You can substitute equation 2 into equation 1:
4(y+4)-2y=2
Then solve
4y+16-2y=2
2y+16=2
2y=-14
y=-7
x=-7+4
x=-3
Answer: FALSE
Actually, the answer to this question depends on whether the clause is reversed or not.
Since we are not told whether the the clause is reversed or not. It is safe to assume that it was retained (i.e. not reversed). So the answer to this question is FALSE because if one takes a true "if-then" statement, inserted a 'not' in each clause, and retained the clauses, the new statement would NOT be true.
On the contrary, if the clause is reversed, the answer would be TRUE, because if one takes a true "if-then" statement, inserted a not in each clause, and reversed the clauses, the new statement would also be true.
