Answer : The speed of both planes is 61.25 mph and 18.75 mph respectively.
Explanation:
Let the speed of first plane be x mph
Let the speed of second plane be y mph
Since we have given that difference of speeds is 80 mph
i.e. x - y= 80 (
1)
Distance between two planes = 3400 miles
As they are flying towards each other i.e. they are in the opposite direction.
So, Relative speed will be the sum of their speeds i.e.
Relative speed = x + y
And we know speed = 
Speed= 
⇒ Speed = 42.5 mph
Hence, Relative speed becomes 42.5 mph
⇒ x+y=42.5 ( 2)
Now, by using the elimination method of solving the system of equation, we have ,
x= 61.25 mph
and y = 18.75 mph
1.You have that:
<span>
- One tin of 500 mL blue paint costs $11.50.
-Jason needs </span><span>4 L of blue paint.
2. First, you must convert 4 L to mL, as below:
1 L----1000 mL
4 L----x
x=4x1000/1
x=4000 mL
3. If 500 mL costs $11.50, h</span><span>ow much will it cost 4000 mL?
</span><span>
500 mL-----$11.50
4000 mL---x
x=(4000 mL)($11.50)/500 mL
x=$92.00

Answer:
Row 1 = 2 white flowers
Row 2 = 3 white flowers
Row 3 = 4 white flowers
Step-by-step explanation:
Instead of having 1.5 times as many pink flowers as white flowers, Molly has decided to plant a garden with twice as many pink flowers as white flowers per row. If she plants 3 rows, with 4, 6, and 8 pink flowers, how can you find the number of white flowers in each of those rows?
Let
White flowers = x
Pink flowers = 2x
Molly plants 3 rows with 4, 6 and 8 pink flowers
Number of white flowers in each row is
Row 1
Pink flowers = 4
2x = 4
Divide both sides by 2
x= 2
White flowers = 2 in row 1
Row 2
Pink flowers = 6
2x=6
Divide both sides by 2
x= 3
White flowers in row 2 = 3
Row 3
Pink flowers = 8
2x=8
Divide both sides by 2
x= 4
White flowers in row 3 = 4
Therefore, the number of white flowers in each rows are 2, 3 and 4 respectively
Two events are said to be Disjoint or Mutually Exclusive if the two events can not happen at the same time.For example when we throw a die getting an even number is disjoint to getting an odd number.
I.e Probability(A∩B)=0
Let me explain this concept through venn diagram.
Pr[A∪B]=0.7, Pr[A]=0.25
Since events are Disjoint
Pr[A∩B]=0
Pr[A∪B]=Pr[A] + Pr[B]
0.7=0.25 +Pr[B]
0.7-0.25=Pr[B]
⇒Pr[B]=0.45=45/100=9/20
Now events are said to be independent if Pr[A and B]=Pr[A] ×Pr[B]
Events are said to be independent if occurrence of one is not affected by occurrence of other.For example getting multiple of 2 as one event and getting multiple of 3 as second event when we throw a die.
Pr[A∪B]=0.7, Pr[A]=0.25
Pr[A∪B]= Pr[A]+ Pr[B]-Pr[A∩B]
But Pr[A∩B]= Pr[A] ×Pr[B]
⇒Pr[A∪B]= Pr[A]+ Pr[B]- Pr[A] ×Pr[B]
⇒0.7=0.25+p-0.25×p
⇒0.7-0.25=p- 0.25 p
⇒0.45=0.75 p
⇒p= 0.45/0.75
⇒p =3/5
Answer:
A, B, C
Step-by-step explanation:
A = -8
B = |-6| = 6
C = |11| = 11
Least to greatest, negatives are the least and between 6 and 11, 11 is the greatest.
