<span>A
grade has 81 girls and 72 boys. The greatest split into groups that have the
same ratio girls the boys as a whole grade.
=> Find how many girls are in a group that has 16 boys
Formula and Ratio:
=> 81 : 72 = x : 16 – we need to find the value of girls or the number of
girls in the given ratio.
=> 16 * 81 = 1 296
=> 1 296 / 72 = 18
Therefore the value of girls numbers is 18. The new ratio will be:
18 : 16

Answer:
A. 70 miles per hour B. 620 miles from home
Step-by-step explanation:
This function is a linear equation, following the slope-intercept form of a line. This standard form is y = mx + b, where m is the slope and b is the y-intercept. The slope of a line is the rate at which the steepness of the line is changing. The y-intercept is where the function is "starting".
In our case, the number in the rate of change position is 70. It is being multiplied by t. If t = 1, that means that after 1 hour, we have gone 70 miles. If t = 2, that means after 2 hours we have gone 140 miles. If t = 3, that means that after 3 hours, we have gone 210 miles; etc. That number in the slope position represents the rate at which you are traveling PER HOUR; the slope.
The "starting" position of day 2 is found in the y-intercept. Replacing x with 0, meaning NO time has gone by at all, at the beginning of the second day, we are starting 620 miles from home.
