The unit rate of 600 miles in 7 hours is 85.71 miles per hour.
Given that, distance= 600 miles and time= 7 hours.
What is the unit rate?
Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Here unit rate is
Speed =Distance/Time
= 600/7
= 85.71 miles per hour
Therefore, the unit rate of 600 miles in 7 hours is 85.71 miles per hour.

Answers
m is the slope and b is the y-intercept.
y-intercept is when x is 0 and x-intercept is when y is 0. So if x is 0, y=m(0)+b which is y=b. So on the graph y will be b when x is 0.
So in y=7x+2, 7 is the slope and 2 is the y-intercept.
y = mx + b
where: m = slope; b = y-intercept.
Using the above format,
y = 7x + 2
m = 7 ; b = 2
The slope of the equation is 7.
The y-intercept of the equation is 2.

Answer:
112
Step-by-step explanation:
Given z is directly proportional to x then the equation relating them is
z = kx ← k is the constant of proportionality
To find k use the condition x = 3 when z = 48
k = =
= 16, thus
z = 16x ← equation of proportionality
When x = 7, then
z = 16 × 7 = 112

nn is 80% of yy
yy is the whole value.
7 and nn are the parts. 10% and 80% are its corresponding percentages.
To get the whole value using part and its corresponding percentage, divide the part by its percentage.
7 ÷ 10% = 70 ← value of yy
Since we already know the whole value, we simply multiply the percentage of the part to get the value of the part.
70 * 80% = 56 ← value of nn
