20% = 0.20.2 * 1630 = 326
To solve this problem, just use multiplication.
You can somewhat think of this situation as a sort of tree. You start with 7 large branches representing the pants, then for every one of those you have 3 medium-sized branches to represent the pairs of pants. Each one of those has 5 sticks for the ties, which in turn each have 6 leaves to represent the jackets and therefore a complete outfit. The solution is found by getting the total number of leaves on the tree.
The number of different groups can be found by finding 9C3 (Using combinations)
We will find combinations from n = 9 to r = 3
Therefore, 9C3 = 9!/6!*3! = (9*8*7*6!)/(6!*3*2)
= 3*4*7
= 84 ways.
Answer: The car can travel 525 miles on 15 gallons of gasoline.
Step-by-step explanation:
Gas mileage of the car is the number of miles that it can travel on one gallon of gasoline. If the car travels 35 miles per gallon, that means its gas mileage is number of miles travelled / number of gallons of gasoline used.
If the car has 15 gallons of gasoline to travel with, the distance that it can travel would be
Gas mileage of the car × the number of gallons of gasoline it has to travel with. It becomes
35 × 15 = 525 miles
Answer: ∆LAW ≅ ∆WKL
By rule - ASA congruence postulate.
Step-by-step explanation:
Given: In ∆LAW and ∆WKL
AW⊥WL and WL⊥KL
therefore, by ASA postulate of congruence
∆LAW ≅ ∆WKL
- ASA postulate says that if two angles and the included side of one triangle are congruent to two angles and the included side of second triangle, then the triangles are said to be congruent.
