Answer: The answer is 60
Step-by-step explanation: 40% = .4 because % means hundredths. So 40% = 40/100 = .4
Let x be the total number of marbles.
Then, .4x = 24
Divide both sides by .4
x = 60 and 24 is 40% of 60 marbles

Answer:
Option 4 is correct.
The equation
is equivalent to 
Step-by-step explanation:'
Given equation: 
First group the terms with x and those with y;

Next, we complete the squares.
We can do this by adding a third term such that the x terms and the y terms are perfect squares.
For this we must either add the same value on the other side of the equation or subtract the same value on the same side so that the equality is maintained.
⇒
or



Add 360 on both sides we get;

Simplify:

Therefore, the given equation is equivalent to 
Answer:
Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.
Step-by-step explanation:
We know that the Area of a Rectangle is:
A = L × W
From the Floor Plan, we know that the Width of the kitchen is 5m. We also know that the Length is 7m.
Now input what we know into our equation:
A = L ×<span> W
</span>A = 7m ×<span> 5m
</span>A =
