The value of greta's rolls of coins is $121.00. if pennies and dimes come in
rolls of 50 coins each, and nickels and quarters come in rolls of 40 coins
each, which of these combinations could greta have?

There are a lot of combinations possible

Step-by-step explanation:

One of them would be that each roll of quarters is $10 and each roll of pennies is 50cents so she could have 12 rolls of quarters and 2 rolls of pennies

The correct answer 8 rolls of pennies 6 rolls of nickels, 3 rolls of dimes, and 9 rolls of quarters

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

hey there : ) your answer would be a.
