Multiply −1 1/6 by 7. Write the answer as a mixed number.
To multiply -1 1/6 by 7, we first need to convert -1 1/6 to an improper fraction.
-1 1/6 = -6/6 - 1/6 = -7/6
Now, multiplying -7/6 by 7, we get:
(-7/6) * 7 = -49/6
To express the answer as a mixed number, we divide the numerator (-49) by the denominator (6):
-49 ÷ 6 = -8 remainder 1
Thus, the answer is -8 1/6.
-1 1/6 = -6/6 - 1/6 = -7/6
Now, multiplying -7/6 by 7, we get:
(-7/6) * 7 = -49/6
To express the answer as a mixed number, we divide the numerator (-49) by the denominator (6):
-49 ÷ 6 = -8 remainder 1
Thus, 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 on the lot that are both gray and electrically powered, we divide the number of cars that meet both criteria (13) by the total number of cars on the lot (25).
So, the fraction is 13/25.
So, the fraction is 13/25.

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.(1 point)
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 find 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 the adjustment (3.5 minutes).
Rate of change in altitude = Change in altitude / Time
Rate of change in altitude = 4,000 feet / 3.5 minutes
Calculating this quotient, we get approximately 1142.86 feet/minute.
Rounded to the nearest hundredth, the rate of change in the plane's altitude is 1142.86 feet/minute.
Rate of change in altitude = Change in altitude / Time
Rate of change in altitude = 4,000 feet / 3.5 minutes
Calculating this quotient, we get approximately 1142.86 feet/minute.
Rounded to the nearest hundredth, the rate of change in the plane's altitude is 1142.86 feet/minute.

To find the change in the amount of water in 1 minute, we divide the amount of water removed (250 gallons) by the time it took to remove it (5 minutes):
Change in water in 1 minute = Amount of water removed / Time
Change in water in 1 minute = 250 gallons / 5 minutes
Calculating this quotient, we get 50 gallons.
Therefore, the change in the amount of water in 1 minute is 50 gallons.
Change in water in 1 minute = Amount of water removed / Time
Change in water in 1 minute = 250 gallons / 5 minutes
Calculating this quotient, we get 50 gallons.
Therefore, the change in the amount of water in 1 minute is 50 gallons.

To solve the expression (-4) × (75) × (-34) ÷ (715), we perform the multiplication first, then the division:
(-4) × (75) × (-34) ÷ (715) = (-4) × (-2550) ÷ (715) = 10200 ÷ 715
Evaluating the division, we get:
10200 ÷ 715 ≈ 14.265
Therefore, the result of the expression is approximately 14.265.
(-4) × (75) × (-34) ÷ (715) = (-4) × (-2550) ÷ (715) = 10200 ÷ 715
Evaluating the division, we get:
10200 ÷ 715 ≈ 14.265
Therefore, the result of the expression is approximately 14.265.
that is not one of the answers
Apologies for the mistake. Let's re-evaluate the expression.
(-4) × (75) × (-34) ÷ (715)
First, we simplify the multiplication:
(-4) × (75) × (-34) = 10200
Then, we divide the result by 715:
10200 ÷ 715 ≈ 14.265
Therefore, the correct answer is approximately 14.265.
(-4) × (75) × (-34) ÷ (715)

10200 ÷ 715 ≈ 14.265
Therefore, the correct answer is approximately 14.265.
se the properties of operations and rules for multiplying and dividing signed numbers to solve:
(−4)×(7/5)×(−3/4)÷(7/15)
(−4)×(7/5)×(−3/4)÷(7/15)
To solve the expression (-4) × (7/5) × (-3/4) ÷ (7/15), we apply the rules for multiplying and dividing signed numbers.
First, we simplify the multiplication:
(-4) × (7/5) × (-3/4) = (4/1) × (7/5) × (3/4) = (4 × 7 × 3) / (1 × 5 × 4) = 84/20
Next, we simplify the division:
(84/20) ÷ (7/15) = (84/20) × (15/7) = (84 × 15) / (20 × 7) = 1260/140
Simplifying the fraction, we have:
1260/140 = 9
Therefore, the result of the expression is 9.
First, we simplify the multiplication:
(-4) × (7/5) × (-3/4) = (4/1) × (7/5) × (3/4) = (4 × 7 × 3) / (1 × 5 × 4) = 84/20
Next, we simplify the division:
(84/20) ÷ (7/15) = (84/20) × (15/7) = (84 × 15) / (20 × 7) = 1260/140
Simplifying the fraction, we have:
1260/140 = 9
Therefore, the result of the expression is 9.
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 solve the problem, we need to determine the time it will take for the fish to go from a depth of -10.8 meters to a depth of -37.8 meters, descending 1.5 meters every 2 minutes.
First, we calculate the difference in depth: -37.8 meters - (-10.8 meters) = -37.8 meters + 10.8 meters = -27 meters.
Next, we divide the difference in depth by the rate at which the fish descends: -27 meters ÷ 1.5 meters/2 minutes = -27 meters × 2/1.5 meters/minute
Simplifying the expression, we have: -27 meters × 2/1.5 meters/minute = -36 minutes
Therefore, it will take the fish approximately 36 minutes to reach a depth of -37.8 meters.
This means that after 36 minutes, the fish will have descended to a depth of -37.8 meters, or 37.8 meters below sea level.
First, we calculate the difference in depth: -37.8 meters - (-10.8 meters) = -37.8 meters + 10.8 meters = -27 meters.
Next, we divide the difference in depth by the rate at which the fish descends: -27 meters ÷ 1.5 meters/2 minutes = -27 meters × 2/1.5 meters/minute
Simplifying the expression, we have: -27 meters × 2/1.5 meters/minute = -36 minutes
Therefore, it will take the fish approximately 36 minutes to reach a depth of -37.8 meters.
This means that after 36 minutes, the fish will have descended to a depth of -37.8 meters, or 37.8 meters below sea level.
