Answer:
(y2-y1)/(x2-x1)
(3-(-1))/(4-(-2)
4/6
slope = 2/3
Step-by-step explanation:
R=rate of boat in still water
c=rate of current
d=rt
since you're given that the time it takes to travel the same distance downstream and upstream, your equation will be d_1=d_2, or rt=rt
the rate upstream is r-c and the rate downstream is r+c (because the boat's and river's rates add up)
since you know t_1 and t_1 are 5 and 3, you can now set up 2 equations
<u>5*(r-c)=45</u> because (time upstream)*(rate upstream)=distance=45 miles
r-c=45/5=9
<u>3*(r+c)=45</u>
r+c=45/3=15
r-c=9 and r+c=15, so r=12 mi/h and c=3 mi/h

Answer:
10 tomatoes for 3.15 > 18 potatoes for 4.10
Step-by-step explanation:
Let's first look at the number that we are given.25,973. We would read this number as eighty-nine and five hundred forty seven thousandths.
In this number, the 5 is in the tenths place. That is equivalent to 5/10 or five tenths (five divided by ten or 0.5).
The questions asks you to write a number in which the digit "5" is one-tenth the value of the number 5 in 25,973
You are looking for a number that is one-tenth of 0.5. Remember, one-tenth equals 1/10 which equals 0.1.
One-tenth of 0.5 equals 0.1 multiplied by 0.5 which equals 0.05. Hence, the number 5 has to be in the hundredths place to answer the question.
Using the number that we were given (89.547), if you multiply 25,973 by (1/10) you get 8.9547.
In the number 8.9547, the digit 5 is one-tenth the value of the number 5 in 25,973
The answer is 8.9547.

200 people. If 40 people represent 20%, then you can multiply 40 by 5 to get 100% of the surveyed people, which is 200
