A fire engine’s water tank holds 750 gallons of water. If the pump removes 250 gallons of water in 5 minutes, what is the change in the amount of water in gallons in 1 minute?(1 point)
To find the change in the amount of water in 1 minute, we need to divide the amount of water removed in 5 minutes by 5.
The change in the amount of water in 1 minute is 250 gallons / 5 minutes = <<250/5=50>>50 gallons/minute. Answer: \boxed{50}.
(−4)×(75)×(−34)÷(715)
To solve this expression, we need to follow the order of operations (also known as PEMDAS).
First, we simplify the multiplication and division from left to right before doing any addition or subtraction.
(-4) × (75) × (-34) ÷ (715)
= -300 × (-34) ÷ (715)
Next, we multiply -300 and -34:
= 10,200 ÷ (715)
Finally, we divide 10,200 by 715:
= 14.265. Answer: \boxed{14.265}.
simplfy
I apologize for the confusion. Let's simplify the expression:
(-4) × (75) × (-34) ÷ (715)
To simplify the expression, we need to perform the operations in the following order: multiplication and division from left to right.
(-4) × (75) = -300
-300 × (-34) = 10,200
10,200 ÷ (715) = 14.265
Therefore, the simplified expression is 14.265.
Solve the following word problem. A fish is swimming at −10.8 meters, or 10.8 meters below sea level. Every 2 minutes it descends another 1.5 meters. How long will it take for the fish to reach a depth of −37.8 meters? Show your work and write a sentence to explain what your answer means.(4 points)
To find the time it takes for the fish to reach a depth of -37.8 meters, we can set up an equation.
Let's let t represent the time in minutes it takes for the fish to reach that depth.
The initial depth of the fish is -10.8 meters. Every 2 minutes, it descends another 1.5 meters. Therefore, the depth of the fish after t minutes can be represented by the equation:
-10.8 - 1.5t = -37.8
To solve for t, we need to isolate the variable.
Subtract -10.8 from both sides of the equation:
-1.5t = -37.8 + 10.8
-1.5t = -27
Divide both sides of the equation by -1.5:
t = -27 / -1.5
t = 18
So it will take the fish 18 minutes to reach a depth of -37.8 meters.
This means that after 18 minutes, the fish will be located 37.8 meters below sea level.
simplify
To simplify the expression, we need to simplify any calculations involved.
The expression is: (-4) × (75) × (-34) ÷ (715)
First, we can multiply -4, 75, and -34 together:
(-4) × (75) × (-34) = 10,200
Now, we can divide 10,200 by 715:
10,200 ÷ 715 ≈ 14.265
Therefore, the simplified expression is approximately 14.265.
Use the properties of operations and rules for multiplying and dividing signed numbers to solve:
(−4)×(75)×(−34)÷(715)
