Answer: 18 days.


Step-by-step explanation:

Given: Ronald and Tim both did their laundry today. Ronald does laundry every 6 days and Tim does laundry every 9 days.

To find, number of days will it be until Ronald and Tim both do laundry on the same day again, we need to find the least common multiple of 6 and 9.

We know that 6×3=18 and 9×2=18

Thus, the least common multiple of 6 and 9=18

Therefore, after 18 days Ronald and Tim both do laundry on the same day again.

Rectangle ABCD is congruent to rectangle A″B″C″D″ . Which sequence of transformations could have been used to transform rectangl
Cerrena [4.2K]
Answer:- A. Rectangle ABCD was translated 8 units left and then 7 units down.

Explanation:-
We can see vertex A(2,4) of rectangle ABCD moves to A"(-6,-3), in a way that A translated 8 units left (-8)and 7 units down(-7) to A".
i.e.(2-8,4-7)=(-6,-3)
Similarly the other vertices of rectangle ABCD moves to form rectangle A"B"C"D"
B (2,2) → B" (-6,-5)
C (6,2) → C" (-2,-5)
D(6,4) → D" (-2,-3)

1:\frac{8}{40} =  \frac{1}{5}
2:\frac{40-8}{40}= \frac{32}{40} =  \frac{4}{5}
3:\frac{9}{40}
4:\frac{40-4}{40}=  \frac{36}{40}  =\frac{9}{10}
5:500×\frac{4}{40}=50
