Answer:
Option D.
Step-by-step explanation:
From the given figure it is clear that the three quadrilaterals on a coordinate grid are squares because all sides of each quadrilaterals are same and all interior angles are right angles.
Side length of square M = 2 units
Side length of square N = 2 units
Side length of square O = 4 units
The corresponding sides of congruent figures are congruent. So,
Square M ≅ Square N
The corresponding sides of similar figures are proportional. So,
Square M Square N
Square M Square O
Square N Square O
M and O are similar but not congruent.
Therefore, the correct option is D.

Answer:
Step-by-step explanation:
We are given that
Height of man=5 foot
Height of street light=20ft
We have to find the rate of change of the length of his shadow when he is 25 ft form the street light.
ABE and CDE are similar triangle because all right triangles are similar.
Hence, the rate of change of the length of his shadow when he is 25 ft from the street light=
Number of days Val rented the bicycle is 8
<h3><u>Solution:</u></h3>Given that val paid a flat rental fee of $55.00 plus $8.50 each day
The total cost was $123
To find: number of days she rented the bicycle
Let "a" be the number of days she rented the bicycle
Rental fee = $55.00
Fee for one day = $ 8.50
So total cost is equal to rental fee and fee for "a" days
Total cost = rental fee + (number of days she rented the bicycle x Fee for one day)
123 - 55 = 8.50a
8.50a = 68
Thus number of days she rented the bicycle is 8
