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

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

its very big question plz make it small
