Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m
Answer:
I think is C like I said not quite sure...
Answer:
6
Step-by-step explanation:
Question tests the ability to get quotient
Here, 32 ft is divided by 5’3”
Normally, ft is denoted by ' while inches is denoted by ". So we divide 32 ft by 5ft and 3 inches
First, we convert dimensions into similar units. To convert 5’3” to ft, we divide 3” by 12 hence 3÷12=0.25'
The total is now 5.25'
Now
32'÷5.25'=6.1538461538461
This means, we shall obtain 6 whole pieces with some remainder. Since the question needs the whole pieces only, then the answer is 6
My best guess is a line graph because it shows the consistent numbers and then you can lay them all out after you have completed the graph
We are given the two functions
and
. Since the question is asking us for the value of x when f(x) is equal to g(x), all we need to do is equate the respective expressions together. This is what the result should be:
Now, just solve for x. If you want to save some time, you can use logic and then algebra. To do this, look at the square root. We cannot have an imaginary number, so we can rule out the first two options. Now, we are left with x = 2 and x = 4. When we plug in each x-value to the equation, only 4 works out with a result of 0.5 = 0.5. Therefore, the solution to f(x) = g(x) is
D) x = 4. Hope this helps and have a great day!
