The answer is B. A reflection across the x-axis.
If you make a proportion,
12 18
--- = ---
10 x
when you cross multiply
12x=180
x=15
EF= 15
Answer:
In each place there must be more 100 pennies, but as the total 250 pennies, there are several ways that the money is distributed.
Because there may be 101 pennies in the box and 149 pennies in the bank, but it can also be the opposite; in the box 149 pennies and in the bank 101 pennies.
Therefore, there are many options to answer the question, as long as it is met that there are more than 100 pennies in one place.
Answer:
30
Step-by-step explanation:
third side is the hypotenuse since it is opposite to 90 degree.
using pythagoras theorem
a^2 + b^2 = c^2
24^2 + 18^2 = c^2
576 + 324 = c^2
900 = c^2
= c
30 = c
therefore third side is 30.
20^2 + 21^2 = 27^2
400 + 441 = 729
881 = 729 (does not equal)
