Divide the two numbers.
5/2 / 1/4
Flip the 2nd fraction and multiply:
5/2 * 4/1
20/2
10
So the marathon runner travels at a unit rate of 10 MPH.
Answer:
199 a 426 students
Step-by-step explanation:
first to see what amount we are talking about in each case, let's see how many students each percentage represents
22% of students: (22 * 1420 students) /100 = 312.4 students
8% of students: (8*1420 students)/100 = 114.6 students
that is, that the average number of students who work part time is 312.4 students. And that number can vary up to 114.6 students above and up to 114.6 students below
that can be expressed as
22% + 8% = 312.4 + 113.6 = 426 students
and
22% -8% = 312.4-113.6 = 198.8≅ 199 students
It's simplest form is 14/15
Answer:
D. 7
Step-by-Step Explanation:
To solve this problem, we need to know a certain equation: the equation of a line in the slope-intercept form:
y = mx + b; where m = slope and b = y-intercept.
First, substitute the known values into the equation. I will use the coordinate (3, 19) for x and y values.
y = 19
m = 4
x = 3
b = ?
19 = (4)(3) + b
Then, all we have to do is solve for b.
19 = (4)(3) + b
19 = 12 + b
19 - 12 = 12 + b - 12
7 = b
So, the y-intercept of the line is 7.
Hope this helps!
