1. A school reopens at 7:30 am and closes at 1:00 pm with recess of 30 minutes. Find the ratio between recess and teaching period 2. Find the value of x
2x = 64

don't give irrelevant answers to get the point
Answer must be well explained

Answers :-

Step by step explanation :-

1.

No. of hrs school is kept open

=> 5hrs 30 min

Working hrs = 5hrs 30 min - 30 min

=> 5hrs

Ratio between recess time :-

=> 30 min to 5hrs

=> 30 min to 300 min

=> 1 : 10

2.

2x = 64

( take lcm )

=> 2x = 2⁶

=> x = 6

Hope it helps ~

Opening time = 7:30 am

Closing time = 1:00 pm

Time between = 5:30 minutes

Recess time = 05:30- 00:30

= 5 hrs

30 minutes to 5 hours

OR

30 minutes to 300 minutes

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

2x=64

Solve for x ~

Take LCM of 64 to make bases of both sides same base of exponent

2x=2⁶

x=6

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

translate k to n and reflect across the line containing jk.
