Answer:
interval 41-50 and 61-70 i think
Step-by-step explanation:
Answer:
20 cm
Step-by-step explanation:
So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.
Use the slopeformula 3 times and you should found the pair
Answer:
Step-by-step explanation:
Harvey rides his bike at an average speed of 12 miles in 1 hour, 24 miles in 2 hours, and so on. Let h be the number of hours he rides and d be distance traveled. Write the equation for the relationship between distance and time in point-slope form.
----
You have three points relating time and distance:
(1,12),(2,24),(3,36)
-----
The slope for your equation would be (24-12)/(2-1) = 12/1 = 12
-------------------------------
The intercept is the distance you would travel in no time; that would be zero.
---------------------------------
The equation is: distance = 12(time)
d = 12t
70% of the trip length, t, is 35 miles. Find t:
0.70t = 35. Dividing both sides by 0.70, we get:
35
t = ----------- = 50
0.70
The total trip length is 50 miles.
