Step-by-step explanation:
hope you can understand
The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes
20 minutes = 20 / 60 = 1/3 of an hour
45 miles per hour x 1/3 of an hour = 15 miles driven
18 total miles - 15 miles driven = 3 miles left
she then drove at 20 miles per hour
20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes
3 miles x 3 minutes = 9 minutes to drive the final 3 miles
20 minutes + 9 minutes = 29 total minutes to drive to work
she left at 7:15
7:15 + 20 minutes = 7:35 am she arrived at work
Answer:
9 meters
Step-by-step explanation:
To find the area of a rectangle you do length times width. To find a side length, or the width divide the area by the length. 99/11=9.
The width is 9 meters.
Answer with explanation:
⇒The Meaning of Additive Identity is that element in a set when added to any member or elements of set yields that element.
Consider a system of forces under a set F , which is a vector space under a field .
The set F having three forces a, b, c will be a vector space if,
1.→ a +(b+c)=(a+b)+c
2.→ a+b=b+a
3.→There must exist a force equal to 0, such that when any of the forces added to 0 the resultant is force itself.
That is , a+0=a=0+a
→→So,If you consider any vector space over a field ,there exist an element in that set equal to 0, when added to any member of the elements of the set the result being that element.So, element 0 is the Additive Identity of any vector space.
