A motorboat, that has speed of 10 km hour in still water, left a pier traveling against the current of the river. Forty-five minutes after the boat left the pier, the motor of the boat broke, and the boat began drifting with the current. After three hours of drifting with the current, the boat was back at the pier where it had started. What is the speed of the current of the river?
9514 1404 393
Answer:
2 km/h
Step-by-step explanation:
distance = speed × time
The boat's progress upriver can be modeled by ...
(10 -c)(3/4) +(0 -c)(3) = 0
7.5 -3.75c = 0 . . . . simplify
2 -c = 0 . . . . . . . . . divide by 3.75
c = 2 . . . . . . add c
The speed of the current is 2 km per hour.

Answer:
I am pretty sure B is correct answer
Answer:
A. Slope is -5. Y-intercept is (0,7)
Step-by-step explanation:
1. Find the slope using the slope formula and the coordinates
Remember, the slope formula is: y2-y1/x2-x1
You'll use the coordinates (0,7) (4, -13) to plug into the formula.
-13-7/4-0
= -20/4
= -5
Slope is -5
2. Find the y-intercept.
First, write the equation of the line in point-slope form: y-y1=m(x-x1)
M is slope and y1 and x1 can be from any ordered pair (as long as they're from the same one). Let's use (0,7)
y-7=-5(x-0)
Simplify the equation.
y-7=-5x+0
y=-5x+7
3. Now the equation is in y-intercept form, or y=mx+b. Again, M is slope. B is the y intercept. So, the y-intercept is 7

the speed of light is approximately 3 x 10 to the 8th power meters per second, while the speed of sound is approximately 3.4 meters per second. How many times faster is the speed of light than the speed of sound?
Answer:
The speed of light is 8.8x10⁵ times faster than the speed of sound.
Step-by-step explanation:
We can find how many times faster (R) is the speed of light than the speed of sound as follows:
[tex] R = \frac{c}{v_{s}} [/tex]
Where:
c: is the speed of light = 3x10⁸ m/s
[tex]v_{s}[/tex]: is the speed of sound = 340 m/s (the value given in the statement, 3.4 m/s, is wrong)
[tex]R = \frac{3 \cdot 10^{8} m/s}{340 m/s} = 8.8 \cdot 10^{5}[/tex]
Hence, the speed of light is 8.8x10⁵ times faster than the speed of sound.
I hope it helps you!

Answer:
1005 ft squared (B)
Step-by-step explanation:
The far left area:
30*15=450
The middle area:
-Since there is an eight feet being subtracted it is:
22*15=330
The last side:
-Since there is two 15's at the bottom we must subtract 30 from 45:
15*30*1/2=225
Add the area together:
450+330+225=1005
1005 ft squared

Find the principal of interest!! random answers will be reported
1. Interest: $640
Rate: 4%
Time: 1 year
2. Interest: $2,016
Rate: 12%
Time: 3 years
Answer:
4: $16,000
5: $4978.66
6: .086278 or 8.62%
Step-by-step explanation:
For the entirety of this problem I am going to assume that the interest is compounding annually
4: to find the interest earned in a period you have the following equation
(principle*(1+i)^n)-Principle
We can plug in the values we know
principle=p
(p*1.04)-p=640
This means that p=640/.04
p=16000
5: This is the same deal as the other one
2016=(p*(1.12)^3)-p
Solve this and get 1.404928p-p=2016
This means that .404928p=2016
Which means that p=4978.66
6: This one is slightly different but we can still use the same formula
720=4000((1+i)^2)-4000
We can add 4000 and then divide by 4000 to get
1.18=(1+i)^2
Take the square root of both sides and subtract 1 to solve for i
i= .086278 or 8.62%
Answer:
1. Interest: $640
Rate: 4%
Time: 1 year
2. Interest: $2,016
Rate: 12%
Time: 3 years

Francine rolls two 6-sided number cubes. What is the probability that she rolls a sum equal to 6? Use the diagram of the sample space to help you.
Answer:
5/36
Step-by-step explanation:
Basally you just need to see how many of the dices added up to 6. (6 and 1 don't count because that would add up to 7.)
Then find how many possibilities there were, in this case 36. 5 out of 36.
In other cases you would simplify if need be.
