Solve the equation:
1 1/6 x 7
Write the answer as a mixed number
1 1/6 x 7
Write the answer as a mixed number
To solve the equation, we simply multiply 1 1/6 by 7.
1 1/6 is equivalent to 7/6.
Multiplying 7/6 by 7:
(7/6) * 7 = 49/6
To write the answer as a mixed number, we divide the numerator (49) by the denominator (6) to find the whole number part and the remainder.
Dividing 49 by 6 gives us a quotient of 8 with a remainder of 1.
Therefore, the answer is 8 1/6.
1 1/6 is equivalent to 7/6.
Multiplying 7/6 by 7:
(7/6) * 7 = 49/6
To write the answer as a mixed number, we divide the numerator (49) by the denominator (6) to find the whole number part and the remainder.
Dividing 49 by 6 gives us a quotient of 8 with a remainder of 1.
Therefore, the answer is 8 1/6.
Of the cars in a used-car lot, 25 are the color gray. 13 of the gray cars are electrically powered vehicles. What fraction of the cars on the lot are both gray and electrically powered? Leave your answer in simplified fraction form.
To find the fraction of cars that are both gray and electrically powered, we need to divide the number of gray electric cars by the total number of cars on the lot.
The number of gray electric cars is 13.
The total number of cars on the lot is 25.
Therefore, the fraction of cars that are both gray and electrically powered is 13/25.
The number of gray electric cars is 13.
The total number of cars on the lot is 25.
Therefore, the fraction of cars that are both gray and electrically powered is 13/25.
Lake Profondo has a depth of 84 feet. Lake Segundo is 56 as deep. What is the elevation at the bottom of Lake Segundo? (Remember, the elevation is below sea level. Account for this in your answer.)
The depth of Lake Segundo is 56 feet. Since the elevation is measured from sea level, we will consider the depth as negative.
Therefore, the elevation at the bottom of Lake Segundo is -56 feet.
Therefore, the elevation at the bottom of Lake Segundo is -56 feet.

A pilot is flying an airplane. Due to strong winds, the pilot decides to fly 4,000 feet lower to avoid excessive turbulence. It takes the pilot 3.5 minutes to make this adjustment. Interpret the quotient to describe the rate of change in the plane’s altitude. Give your answer to the nearest hundredth, and remember the plane is descending.
The quotient that best represents the rate of change in the plane’s altitude is ___
feet/minute.
The quotient that best represents the rate of change in the plane’s altitude is ___
feet/minute.
To calculate the rate of change in the plane's altitude, we divide the change in altitude (4,000 feet) by the time it takes to make this adjustment (3.5 minutes).
The quotient that represents the rate of change in the plane's altitude is:
4,000 feet ÷ 3.5 minutes = 1142.857 feet/minute.
Rounding to the nearest hundredth, the rate of change in the plane's altitude is approximately 1142.86 feet/minute.
The quotient that represents the rate of change in the plane's altitude is:
4,000 feet ÷ 3.5 minutes = 1142.857 feet/minute.
Rounding to the nearest hundredth, the rate of change in the plane's altitude is approximately 1142.86 feet/minute.
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?
To find the change in the amount of water in 1 minute, we need to determine how many gallons of water are being removed per minute.
In 5 minutes, the pump removes 250 gallons of water.
To find the amount of water being removed per minute, we divide the amount removed in 5 minutes by the number of minutes:
250 gallons ÷ 5 minutes = 50 gallons/minute.
Therefore, the change in the amount of water in 1 minute is 50 gallons.
In 5 minutes, the pump removes 250 gallons of water.
To find the amount of water being removed per minute, we divide the amount removed in 5 minutes by the number of minutes:
250 gallons ÷ 5 minutes = 50 gallons/minute.
Therefore, the change in the amount of water in 1 minute is 50 gallons.

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.
To solve the problem, we need to determine how long it will take for the fish to reach a depth of -37.8 meters from its starting depth of -10.8 meters.
Every 2 minutes, the fish descends further by 1.5 meters.
We can set up an equation to represent the situation:
-10.8 - (1.5 × t) = -37.8
Here, t represents the number of 2-minute intervals the fish descends.
Multiplying out the equation gives us:
-10.8 - 1.5t = -37.8
Now, let's solve for t:
-1.5t = -37.8 + 10.8
-1.5t = -27
Dividing both sides of the equation by -1.5 gives us:
t = (-27) / (-1.5)
t = 18
Therefore, it will take the fish 18 intervals of 2 minutes each (or 36 minutes) to reach a depth of -37.8 meters.
This means that after 36 minutes of continuously descending at a rate of 1.5 meters every 2 minutes, the fish will reach a depth of -37.8 meters, which is 37.8 meters below sea level.
Every 2 minutes, the fish descends further by 1.5 meters.
We can set up an equation to represent the situation:
-10.8 - (1.5 × t) = -37.8
Here, t represents the number of 2-minute intervals the fish descends.
Multiplying out the equation gives us:
-10.8 - 1.5t = -37.8
Now, let's solve for t:
-1.5t = -37.8 + 10.8
-1.5t = -27
Dividing both sides of the equation by -1.5 gives us:
t = (-27) / (-1.5)
t = 18
Therefore, it will take the fish 18 intervals of 2 minutes each (or 36 minutes) to reach a depth of -37.8 meters.
This means that after 36 minutes of continuously descending at a rate of 1.5 meters every 2 minutes, the fish will reach a depth of -37.8 meters, which is 37.8 meters below sea level.
