The school canteen charges Rs 42 for lunch and Rs 8 for milk for each day. How much money do you spend in 5 days on these things? Write proper steps. State the property used.

Step-by-step explanation:

Cost of lunch for 1 day=Rs42

Cost of lunch for 5 days=Rs42×5

Cost of Milk for 1 day=Rs8

Cost of Milk for 5 days=Rs8×5

Now,

Total cost=42×5+8×5

=5×(42+8)(Taking 5 common)

=5×50

=250

Thus,Total money spent is Rs250

I hope it's helpful!!

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
