Let's denote s as the speed limit. To find the total time it takes for Jack to drive given the speed, we just divide the total number of miles he covered (10 miles) by the speed he's traveling at.
Accounting for the given of the problem, we'll have the following equation:
(from the fact that the difference between the time it takes to drive five miles below the speed limit versus 15 miles below is 2 mins or
hours.)
Since we only have one unknown variable, we can freely solve for s:
(we ignore the negative value since there is no negative <u>speed</u>.)
ANSWER: The speed limit of the freeway is 65 mph.
Answer:
The circumference is 66cm
Radius = Diameter/2
= 21/2 CM
= 10.5 CM
Circumference of a circle = 2πr
= 2 × 22/7 × 10.5 CM
Answer:
+0.8
Step-by-step explanation:
The correlation coefficient is a statistical and arithmetical measure of the force of the relationship among the relative movements of two variables. The values are between the range of -1.0 and 1.0.
When theirs is a calculated number bigger than 1.0 or smaller than -1.0, then that means there was an error in the correlation measurement.
The Correlation Coefficients (R) which is calculated amid the Summer and Winter UHIs is Derived From T s , T a , and T ac a UHI R Between Summer and Winter UHIs Slope.

Answer:
y+1=-3(x-4)
Step-by-step explanation:
first you want to plug in the numbers into the formula which y-y1=m(x-x1).
then you get y+1=-3(x-4)
