Hello!
First of all, we have a 4/52, or 1/13 chance of selecting a pair. Then, we select 1/3 cards 3 times, so we use this as our other fraction.
=
Therefore, we have a 1/39 or about 3%.
I hope this helps!
A good way of doing this problem would be to use cross multiplication of ratios
<u />
Then cross multiply
(10 girls)(270 students)=(X girls)(18 students)
2700=18x
150=x
Answer:
Step-by-step explanation:
50,000 mm=5,000 cm=500 decimeter=50 m=5 decameter
so both are equal.
Because the shape is not undergoing a dilation, the perimeter of the original image and the new image is the same. The only thing that is changing is the placement of the original figure.
I hope this helps! :)
Your problem statement is missing the formula Carrie came up with. It should be The one she started with, divided by m.
... G/m = a
For the values given, the acceleration is
... (7.92 N)/(3.6 kg) = 2.2 m/s²
_____
The unit of newtons is abbreviated N.
1 N = 1 kg·m/s² so dividing by kilograms leaves units of m/s², which are the units of acceleration.
Very likely, your question is not concerned with the units, just the number: 2.2. It's a straight division problem, easily handled by hand, by calculator, or in your head (after you realize 7.92 = 7.2×1.1 = 2×3.6×1.1).
