Answer:
Step-by-step explanation:
The question seeks to examine the knowledge of the concept of perimeter of a square.
A perimeter is the sum total of the distance of all the lengths of the sides of a shape or object in context.
Step 1: Scale the object.
Assume 1 cm = 1 tiny graph square
We can say that in object (Square) ABCD; length AB = BC = CD = AD = 4cm
Step 2: solve for the perimeter.
Formula for the perimeter of a square is = 4 × length
Perimeter= 4 × length
Perimeter= 4 × 4cm
Perimeter= 16 cm.
Answer:
294 square feet
Step-by-step explanation:
If the volume is one side at the 3rd power, then If we know the volume, we calculate the cubic root of 343 that is 7
So 1 side =7
The cube has 6 faces
1 face of the cube is 7*7=49
Six faces =
49*6= 294

Answer:
The correct option is C.
Step-by-step explanation:
According to the given diagram :
Number of blue balls = 3
Number of red balls = 2
Total number of balls as given in the diagram = 2+ 3
= 5
![\text{Probability of drawing a blue card = }\frac{3}{5}](https://tex.z-dn.net/?f=%5Ctext%7BProbability%20of%20drawing%20a%20blue%20card%20%3D%20%7D%5Cfrac%7B3%7D%7B5%7D)
Now, The card is replaced and again a blue card is drawn
![\text{Probability of drawing a blue card again = }\frac{3}{5}](https://tex.z-dn.net/?f=%5Ctext%7BProbability%20of%20drawing%20a%20blue%20card%20again%20%3D%20%7D%5Cfrac%7B3%7D%7B5%7D)
![\text{Hence, Probability of drawing a blue card twice after replacing = }\frac{3}{5}\times \frac{3}{5}=\frac{9}{25}](https://tex.z-dn.net/?f=%5Ctext%7BHence%2C%20Probability%20of%20drawing%20a%20blue%20card%20twice%20after%20replacing%20%3D%20%7D%5Cfrac%7B3%7D%7B5%7D%5Ctimes%20%5Cfrac%7B3%7D%7B5%7D%3D%5Cfrac%7B9%7D%7B25%7D)
Therefore, The correct option is C.
