Answer:
15/121.
Step-by-step explanation:
Probability of picking a red = number of reds in the bag / total number of marbles in the bag
= 3 / (3 + 3 + 5)
= 3/11.
Probability of picking a blue = 5/11.
These 2 events are independent so we multiply probabilities, therefore the
Probability of (a red then a blue) = 3/11 * 5 /11
= 15/121.
Answer:
3 2/3
Step-by-step explanation:
3/4 x 3 2/3
3/4 x 11/3
11 x 3=33
4 x 3=12
33/12
2 3/4
The rate of giant tortoise is 1/10 meters per each second.
The rate of cooter turtle is 1/2 meters per each second.
How long would it take a giant <span>tortoise to travel 5 meters?
1 second : 1/10 m = X : 5 m
1/10x = 5
x = 50 seconds
How much longer would it take a giant tortoise than a cooter turtle to travel 10 meters on land?
1 second : 1/2 m = X : 10 m
1/2x = 10
x = 20 seconds
So the giant turtle can travel 5 meters in 50 seconds.
</span><span>So the cooter turtle can travel 10 meters in 20 seconds.</span>
Answer:
- x = 18
- 45°
Step-by-step explanation:
First part:
- Write out an equation to represent the image: 2x + 3x = 90
- Combine like terms: 5x = 90
- Divide each side by 5 to cancel out the 5 next to x. It should now look like this: x = 18
Second part:
- 90 ÷ 2 = 45°
I hope this helps!
