Joan's remaining distance is reduced by (600 ft)/(3 hours) = 200 ft/hour. She starts with 1600 ft remaining, so her distance remaining (y) after x hours is
.. y = -200x +1600
In order for the distance remaining to be zero, you must have
.. 0 = -200x +1600
.. 200x = 1600
.. x = 1600/200 = 8
It will take Joan 8 hours to hike 1600 ft.
Answer:
9
Step-by-step explanation:
2 raised by 3 = 8
4 * 2 = 8
8 + 8 = 16
16 - 7 = 9
Answer:
Step-by-step explanation:
Slope-intercept form means
where m is given its the slope which is and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,
now we know the value of slope which is given and we found the value of which is 1 so we put these values into our original slope-intercept form equation
Using proportions, it is found that Yes, there could be 5 kids, with 3 boys and 2 girls.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, supposing a total of 5 kids:
- More than 1/2 = 50% are boys, hence there are more than 2.5 boys, as 0.5 x 5 = 2.5.
- Less than 2/3 = 66.67% are boys, hence there are less than 3.33 boys, as 0.6667 x 5 = 3.33.
Hence, Yes, there could be 5 kids, with 3 boys and 2 girls.
