Answer:
470 balls
Step-by-step explanation:
Let the number of tennis balls Kerns have be x and the number of tennis balls Hardy has be 3x. We want to find their difference: 3x-x = 2x
Total no. of balls = Kerns + Hardy
= x + 3x
= 4x
4x = 940
2x =
× 940
= 470
Correct answer is : Area of triangle is 
Solution:-
We can do it in 2 methods.
Method 1:-
Given that AB=6, BC=10 and m∠B = 120
Then area of triangle = 
Let us assume AB is base and D is an altitude from C onto AB.
Then sin(60)= 
CD = BC sin(60)
Hence height =
= 
Hence area of ΔABC =
sq.units
Method2:-
Area of triangle = 
Here a= BC=10, c=AB=6.
Hence area of triangle =
sq.units
Answer:

Step-by-step explanation:
= 2k - x
Given that k = 9, x = 5
= 2(9) - 5
= 18 - 5
= 13

Step-by-step explanation:
Basic Logarithm Tenets
Answer: C 4
Step-by-step explanation:
Use the formula: distance = rate x time
We can say that train 1 travels a distance of x, and train 2 travels a distance of 700 - x
The rate of train 1 is 75 mph, and the rate of train 2 is 100 mph
The time traveled for the two trains will be the same. We can represent that with the variable t.
We have the following equation for train 1:
x = 75t
For train 2, we have this equation:
700 - x = 100t
Use the Substitution Method by replacing x in the equation for train 2 with the value 75t.
700 - 75t = 100t
700 = 175t
700/175 = 4 hours.
It will take 4 hours for the two trains to meet.
