Question

Of the cars in a used-car lot, 2/5 are the color 1/3 the gray cars are electrically powered vehicles. What fraction of th cars on the lot are both gray and electrically powered? Leave your answer in simplified fraction form.

Answer 1

[AI-generated answer — Bot GPT 3.5]

Let's say there are "x" total cars in the lot.

2/5 of the cars are gray, which means there are 2/5*x gray cars.
1/3 of the gray cars are electrically powered, which means there are (1/3)*(2/5*x) = (2/15)*x gray and electrically powered cars.
The fraction of cars that are both gray and electrically powered is therefore (2/15)*x / x = 2/15.
The simplest form of this fraction is 2/15. Answer: \boxed{\frac{2}{15}}.

Answer 2

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.)

Answer 3

[AI-generated answer — Bot GPT 3.5]

Since both lakes' depths are given in feet and we assume that sea level is at 0 feet, the elevation at the bottom of Lake Segundo would be -56 feet. This negative sign indicates that the elevation is below sea level. So, the elevation at the bottom of Lake Segundo is -56 feet. Answer: \boxed{-56}.

Answer 4

Lake Profondo has a depth of 8/4 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.)

Answer 5

[AI-generated answer — Bot GPT 3.5]

Lake Profondo has a depth of 8/4 feet, which simplifies to 2 feet. Lake Segundo is 5/6 as deep as Lake Profondo, so its depth is (5/6) * 2 = 10/6 feet, which simplifies to 5/3 feet.

To determine the elevation at the bottom of Lake Segundo, we need to consider that sea level is at 0 feet. Since the depths of both lakes are below sea level, the elevation at the bottom of Lake Segundo would be -5/3 feet. This negative sign indicates that the elevation is below sea level.

So, the elevation at the bottom of Lake Segundo is -5/3 feet. Answer: \boxed{-\frac{5}{3}}.

Answer 6

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.)

Answer 7

[AI-generated answer — Bot GPT 3.5]

To find the depth of Lake Segundo, we can multiply the depth of Lake Profondo by 5/6:

Depth of Lake Segundo = (5/6) * 84 feet = (5 * 84) / 6 feet = 420 / 6 feet = 70 feet.

Since the depth of Lake Segundo is below sea level, the elevation at the bottom of Lake Segundo would be -70 feet. The negative sign indicates that the elevation is below sea level.

Therefore, the elevation at the bottom of Lake Segundo is -70 feet. Answer: \boxed{-70}.

Answer 15

[AI-generated answer — Bot GPT 3.5]

To convert 4.65 to a fraction, we observe that the number has two decimal places. To convert a decimal with two decimal places to a fraction, we place the decimal part (65) over the appropriate power of ten, which in this case is 100:

4.65 = 4 + 0.65 = 4 + 65/100

Simplifying the fraction 65/100, we can divide both the numerator and denominator by 5:

65/100 = (65 ÷ 5) / (100 ÷ 5) = 13/20

Therefore, 4.65 can be expressed as the fraction 4 + 13/20.

Answer: \boxed{4 \frac{13}{20}}.

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.

Answer 23

[AI-generated answer — Bot GPT 3.5]

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 = Change in altitude / Time

Rate of change = 4000 feet / 3.5 minutes

Calculating this division gives us approximately 1142.86 feet/minute.

Therefore, the quotient that best represents the rate of change in the plane's altitude is approximately 1142.86 feet/minute. Answer: \boxed{1142.86 \text{ feet/minute}}.

Answer 24

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

Answer 25

[AI-generated answer — Bot GPT 3.5]

Given that the fish descends 1.5 meters every 2 minutes, we can find the number of times the fish needs to descend 1.5 meters to reach a depth of -37.8 meters.

To find the number of descents, we calculate the difference between the starting depth (-10.8 meters) and the target depth (-37.8 meters):

Difference = -37.8 meters - (-10.8 meters)

Difference = -37.8 meters + 10.8 meters

Difference = -27 meters

To find the number of descents, we divide the difference by the descent rate:

Number of descents = Difference / Descent rate

Number of descents = -27 meters / 1.5 meters/2 minutes

Number of descents = -27 meters / 0.75 meters/minute

Number of descents ≈ -36

Since each descent takes 2 minutes, the total time it will take for the fish to reach a depth of -37.8 meters is:

Total time = Number of descents × Time per descent

Total time = -36 descents × 2 minutes/descent

Total time = -72 minutes

Since time cannot be negative, we consider the absolute value of the total time:

Total time ≈ 72 minutes

Therefore, it will take approximately 72 minutes for the fish to reach a depth of -37.8 meters.

This means that the fish will descend at a rate of 1.5 meters every 2 minutes until it reaches a depth of -37.8 meters below sea level, which will take approximately 72 minutes.

Answer 26

dude just write it for 3 sentences MAKE IT SIMPLE

Answer 27

[AI-generated answer — Bot GPT 3.5]

The fish descends 1.5 meters every 2 minutes. To reach a depth of -37.8 meters, it needs to descend an additional 27 meters. Since each descent takes 2 minutes, it will take approximately 72 minutes for the fish to reach the desired depth.

To solve (−4) × (75) × (−34) ÷ (715), we can perform the multiplication and division in the given order:

(−4) × (75) × (−34) ÷ (715) = (-4) × (75) × (-34) ÷ (715)

Using the rule for multiplying signed numbers, the product of two negative numbers is positive:

(-4) × (75) × (-34) ÷ (715) = 4 × 75 × (-34) ÷ (715)

Next, we perform the multiplication:

4 × 75 × (-34) ÷ (715) = 300 × (-34) ÷ (715)

Using the rule for multiplying a positive number by a negative number, the product is negative:

300 × (-34) ÷ (715) = -10200 ÷ (715)

Finally, we perform the division:

-10200 ÷ (715) ≈ -14.24

Therefore, the value of (−4) × (75) × (−34) ÷ (715) is approximately -14.24.

Answer: \boxed{-14.24}.
