Answer:
Angle b = 30 degrees
Step-by-step explanation:
3x = 90.
X= 30
Angle b = 30 degrees
Let the x ml of water be mixed with 237 ml of ammonia whose strength is 100%, in order to create a mixture of 75% strength.
The equation required to solve this will be:
237/(237+x)=75/100
solving for x we get:
237/(237+x)=3/4
237×4=3(237+x)
948=711+3x
3x+711=948
3x=948-711
3x=237
x=237/3
x=79 ml
therefore the amount of water to be added will be 79 ml

Step-by-step explanation:
There will be a maximum number of Mondays that can occur in 45 consecutive days when we start with a Monday as the first day.
Now, multiples of 7 are 7, 14, 21, 28, 35, 42, 49, ......
So, if today is Monday, the after 7 days there will be a Monday, after 14 days there will be a Monday and in this way, the 43nd day there will be a Monday.
Therefore, there will be
Mondays with in 45 consecutive days. (Answer)
