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 can be written as -(6/6 + 1/6), which simplifies to -7/6.

Now, we can multiply -7/6 by 7:

-7/6 × 7 = -49/6

To write this as a mixed number, we divide the numerator (-49) by the denominator (6):

-49 ÷ 6 = -8 remainder 1

Therefore, the answer is -8 1/6.

Of the cars in a used-car lot, 2/5 are the color gray. 1/3 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.(1 point)

To find the fraction of the cars on the lot that are both gray and electrically powered, we multiply the fractions for each condition.

The fraction of cars that are gray is 2/5, and 1/3 of those gray cars are electrically powered.

Therefore, the fraction of cars that are both gray and electrically powered is:

(2/5) × (1/3) = 2/15

So, 2/15 of the cars on the lot are both gray and electrically powered.

Lake Profondo has a depth of 84 feet. Lake Segundo is 5/6 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.)

To find the elevation at the bottom of Lake Segundo, which is 5/6 as deep as Lake Profondo, we need to multiply the depth of Lake Profondo by 5/6.

84 feet * 5/6 = 70 feet

The elevation at the bottom of Lake Segundo is -70 feet, as it is below sea level.
