You spend 90 minutes practicing flip tricks and slides on your skate board. the ratio of time spent on flip tricks to time spent on slides is 7: 8. how much time do you spend practicing slides?

48 minutes

Step-by-step explanation:

flip trick : slides

7 : 8

slides =8

7 + 8 = 15

To get time needed in practicing slide;

8/15 × 90 = 720/15

= 48

Therefore the time needed to practice slide is 48 minutes

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
