Kevin started his science test at 2: 34 p. m and finished the test 75 minutes later. kevin has football practice at 4: 15 p. m. how much time did kevin have between the end of the test and the beginning of football practice?

Step-by-step explanation:

Remember that

step 1

we know that

Kevin start his science test: 2:34 p.m (after noon)

Convert hours to minutes

step 2

Kevin finished the test 75 minutes later

so

step 3

Kevin has football practice at 4:15 p.m (after noon)

Convert hours to minutes

step 4

Find out the time between end of test and start of football practice:

Note : The reference for both times is the same ( after noon)

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
