We know that the perimeter of the smaller parallelogram is 12 cm (2*2 + 4*2). Even though they are similar, this does not make the equation 4*2 + 6*2. Instead, try using the equation for missing side lengths: x/2 = 6/4. To make them similar, the value of x is 3. Plug this into the perimeter formula (3*2 + 6*2) and your answer is 18 cm.
Answer:
it may be V ≈ 4191.6 cm3 so sorry if i'm wrong!!!
Step-by-step explanation:
It helps to draw a picture so you can visualize it better.
For the rug, since the area = 144, what two numbers multiplied give you 144? You might already know that 144 is a perfect square, so 12 x 12 = 144. 12 is the length of each side of the rug.
√144 = 12
12 + 3 = 15. (Add 3 because the rug only covers a portion of the floor. The entire floor = the length of the rug + the part that isn't covered)
15 x 15 = 225 ft squared (Multiply both sides of the floor to get the area.)
225 ft squared - 144 ft squared = 81 ft squared <-- your answer
Answer:
15
Step-by-step explanation:
Substitute the values so it becomes 25-20+10. 25-20=5, 5+10=15.
Let the yellow cubes be x
yellow = x
blue = 2x // Blue cubes is twice of yellow
Green = 8x // Green is four times of blue
Ratio:
Yellow : Blue : Green
1 : 2 : 8
P(Yellow) = 1/11

Answer: The probability of getting a yellow cube is 1/11.
