Answer:
1500
Step-by-step explanation:
Total cost would be 60%+40%
Since we have 60% amount already
0.60* total cost=900
total cost=90000/60
=1500
Answer:
it will take them 3.6 hours if their speed is increased
Step-by-step explanation:
First of all, we will need to find the total distance the Geradi family will be travelling. This is a better way to start, as the distance is constant regardless of their change in velocity.
Distance travelled = speed of travel X time taken = 45 X 4 = 180 miles per hour.
If the Geradi family increases their speed to 50 miles per hour, their new time will be got by dividing the total distance travelled by this new speed.
New travel time = 180 miles / 50 miles per hour = 3.6 hours
Answer:
The graph is a horizontal shift of the function two units to the left.
Step-by-step explanation:
The graph is a horizontal shift of the function two units to the left.
Remember that horizontal shifts appear as additions of a constant "c" to the x-coordinate inside the function. When the constant is negative the shift is to the right in |c| units, and when the constant is positive (like in this case) the shift is to the left in |c| units.
In probability, problems involving arrangements are called combinations or permutations. The difference between both is the order or repetition. If you want to arrange the letters regardless of the order and that there must be no repetition, that is combination. Otherwise, it is permutation. Therefore, the problem of arrange A, B, C, D, and E is a combination problem.
In combination, the number of ways of arranging 'r' items out of 'n' items is determined using n!/r!(n-r)!. In this case, you want to arrange all 5 letters. So, r=n=5. Therefore, 5!/5!(505)! = 5!/0!=5!/1. It is simply equal to 5! or 120 ways.
Car A: 18/20(60)=54 mph
Car B: 13/12(60) = 65 mph
So car b travels 11 more miles than car a in one hour
