Answer:
Nicole's average speed is 
.
Step-by-step explanation:
Given,
Speed of Kristen = 
Time taken by Kristen to cover the distance = 
Solution,
We can find out the distance traveled by Kristen by multiplying speed with time.
The distance traveled by Kristen is equal to distance traveled by Nicole.
As the question said Kristen left 2 hours later and cover the distance in 3 hours.
That means Nicole take 5 hours to cover the distance.
So, For Nicole;
Distance = 150 km
Time = 5 hrs
Here we use the formula of speed.
Now substituting the values, we get;
Hence Nicole's average speed is .
Answer:
11
Step-by-step explanation:
First, we need to find the other angles. We'll do this by subtracting 180-141, giving us 39. This is one of the angles needed.
Next, we'll find the other angle by subtracting 180-127, giving us 53.
Now, we can set up the expression: 39 + 53 + 8y = 180
Adding like terms: 92 + 8y = 180
Now, subtracting 180-92 to give us 8y = 88
Diving both side by 8, gives us the value of y = 11.
Answer:
The probability is 2/5 that a $20 bill will be drawn from the wallet.
Step-by-step explanation:
There are 20 total bills in the wallet (5 $5, 7 $10, and 8 $20, 5+7+8=20). So if the finder and returner of the wallet was to be given one of the bills drawn from the wallet there would be an 8/20 chance the owner of the wallet would pull a 20. That's because there are 20 total bills in the wallet and 8 of them are $20.
Simplifying 8/20... 8/20= 4/10= 2/5.
So, there is a 2/5 chance that a $20 bill will be pulled out of the wallet.
Hope this helps!
Answer:
The answer you chose is correct
Step-by-step explanation:
<span>Volume of Cone:
1/3 Bh where B is the area of the base
1/3 Bh = 5
Bh = 15
B = 15/h
The cylinder has the same base area as the cone.
Volume of Cylinder:
V = B*h
B = V/h and B = 15/h
The height of the cone and the cylinder are the same.
V/h = 15/h
Volume of Cylinder = 15.</span>
