For how many minutes did Lynn run at a greater speed than Kael? 12 17 23 28.

Archy [21]

Answer:

28 minutes.

Step-by-step explanation:

We can see from our graph that 12 minutes after starting the race Lynn left Kael behind and he ran at a greater speed till the race ended after 40 minutes.

To find total number of minutes Lynn ran faster than Kael we will subtract 12 from 40.

Therefore, Lynn ran at a greater speed than Kael for 28 minutes.

A movie theater runs its films continuously. One movie runs for 85 minutes and a second runs for 110 minutes. The theater has a

pantera1 [17]

Answer:

10:30PM on the next day

Step-by-step explanation:

First movie = 85mins

intermission = 5mins

Total time = 90mins which is 1:30PM

so the first movie will start again at 1:30PM, which is at the interval of 90minutes and it will run continuously.

Similarly the second movie is 110 minutes long + 5mins intermission which is 115minutes

Time = 1:55PM

so the second movie starts again at 1:55PM and runs continuously at an interval of 115minutes.

We are interested to find when both the movie will start again at the same time, this will be least common multiple of 90 and 115.

LCM of 90,115 = 2070

Therefore after 2070minutes movie will start again at the same time.

2070mins = 34hours and 30 minutes

adding this with noon

10:30PM on the next day.

(X-1) squared + y squared = 36. What is the center and radius of the circle

Leni [432]

Answer:

center (1, 0)
radius 6

Step-by-step explanation:

Given

(x -1)^2 +y^2 = 36

Find

the circle's center and radius

Solution

Compare the given equation to the standard form equation for a circle.

(x -h)^2 +(y -k)^2 = r^2 . . . . . . centered at (h, k) with radius r

This tells you ...

h = 1
k = 0
r = √36 = 6

Your circle is centered at (1, 0) and has a radius of 6.
