"harry had 500 pennies in a jar. he sorted the pennies into 25 different stacks. each stack had the same number of pennies. how many pennies were in each stack? "
a. 20
b. 475
c. 525
d. 12,500

the correct option is A

Step-by-step explanation:

Total number of pennies that Harry had in the jar was 500. He sorted the pennies into 25 different stacks. If each stack had the same number of pennies, it means that the number of pennies in each stack would be the total number of pennies in the jar divided by the number of stacks. Therefore

Number of Pennies in each stack

= 500/25 = 20 pennies

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
