Answer:
q = 70°
Step-by-step explanation:
The 3 angles form a straight angle and sum to 180° , that is
q + 52° + 58° = 180°
q + 110° = 180° ( subtract 110° from both sides )
q = 70°
Answer:
Mr mehra's salary is 26250
Step-by-step explanation:
suppose,
Mr mehra's salary is x
so,
He spends in food = 30% of x
=(30/100) . x [x%=x/100]
= 30x/100
=3x/10
He spends in charity =10% of x
=10x/100
=x/10
Money left = 15750
so,
x = 3x/10 + x/10 + 15750
⇒x - 3x/10 - x/10 = 15750
⇒(10x-3x-x) /10 = 15750
⇒6x/10 = 15750
⇒6x=157500
⇒x = 157500/6
⇒x = 26250
∴Mr mehra's salary is 26250
Answer:
2/3
Step-by-step explanation:
In the 5-minute interval between 7:00 and 7:05, a train to B is the first to arrive. In the 10-minute interval between 7:05 and 7:15, a train to A is the first to arrive. That is, in any 15-minute interval, the probability is 10/15 = 2/3 that a train to A is the first to arrive.
The 1-hour interval between 7 A.M. and 8 A.M. is an integer number of such intervals, so ...
2/3 of the time, he or she will go to destination A.
