Answer:
The first one is 160
The second one is 680
Step-by-step explanation:
Answer:
1). Options (B) and (E)
2). First train is going faster than the second train.
Step-by-step explanation:
1). Rate of 2 gallons of vinegar = $3
Therefore, per gallon rate of vinegar = = $1.5
In $3 quantity of vinegar chef will get = 2 gallons
Therefore, quantity of vinegar chef will get in $1 = gallons
Option (A).
Price of 4 gallons = 4 × $1.5 = $6.00
False.
Option (B)
Price of 1 gallon = $1.50
True
Option (C)
Price of 30 gallons = 30 ×$1.5 = $45
False.
Option (D)
In $2 number of gallons of vinegar chef will get = gallons
False
Option (E)
Number of gallons of vinegar chef gets in $1 =
True
Therefore, Options (B) and (E) are the correct.
2). Speed =
For first train,
Speed =
= 90 miles per hour
For second train,
Speed =
= 40 miles per hour
Since, 90 miles per hour > 40 miles per hour
First train is going faster than the second train.
Answer:
36 minutes when both pipes are working together
Step-by-step explanation:
capacity of tank = 5400 liters
Pipe A flow per mint. = 5400/90 = 60 liters per mint.
Pipe B flow per mint. = 5400/60 = 90 liters per mint.
Flow of A + B per mint. 60 + 90 = 150 liter per mint.
Therefore, 5400 / 150 = 36 minutes to fill the tank
Answer:
I am unable to see the attachment
Answer: See steps below for answer
Step-by-step explanation:
1) Set up an equation
- 40 + x + 3x = 180
- 4x + 40 = 180
- 4x = 140
- x = 35
_____
Part 2:
One angle: 40 degrees
Second angle: x or 35 degrees
Third angle: 3x or 105 degrees
Therefore answer is
35, 40, 105
