Can someone me with 5 to 8, ? with explanation

5) 975 girls      6) $1440      7) $1000        8) 472

Step-by-step explanation: For 5, cross multiply and to get 975 girls. Do the same for 6. For 7, it says that the television is $550, and it is only 55% of her savings. Therefore, to find her original amount, you will put 550 in the numerator and x in the denominator, and cross multiply 55/100 to get 1000. For 8, do the same thing, and put 354 for the numerator, x for denominator, 75/100 and cross multiply.

step-by-step explanation:

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
