Answer:
228cm^2
Step-by-step explanation:
Multiply 18cm by 10cm:
18 x 10 = 180cm^2
So we have the area of the biggest/top part: 180cm^2
For the bottom part:
You've said the length of the bottom side is 8cm.
We know the length of the biggest side: 24cm. And we know the length of the opposite side: 18cm. So, to find the length of the missing side, it's simple subtraction:
24cm - 18cm = 6cm
So now we have lengths for 2 sides: 8cm and 6cm.
Multiply these to give the area:
8cm * 6cm = 48cm^2
Add these areas of both shapes together to give total area:
180cm^2 + 48cm^2 = 228cm^2
Your answer would be C. 27/190.
This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.
The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.
The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.
I hope this helps!
Answer:
20
Step-by-step explanation:
The questions asks about Combinations of Pizza toppings, so by employing the Combination Formula:
Side A’B’ and D’C’ are related because they are both parallel which I think means that they would be the same length
