Answer 8

-84-(-5/6)

Answer 9

[AI-generated answer — Bot GPT 3.5]

To subtract -84 from -5/6, you can follow these steps:

First, simplify the expression -(-5/6) by multiplying -1 with -5/6 to change the sign:

=-1 * (-5/6)
= 5/6

Now, subtract -84 from 5/6:

5/6 - 84

To subtract fractions, we need to have a common denominator. The common denominator between 6 and 1 is 6.

Rewriting -84 as 84/1 with a denominator of 6:

5/6 - 84/1

To have a common denominator of 6, we need to multiply 84 by 6/6:

5/6 - (84)*(6/6)
= 5/6 - 504/6

Now that we have a common denominator, we can subtract the numerators:

5/6 - 504/6 = (5 - 504)/6
= -499/6

Therefore, -84 - (-5/6) equals -499/6.

Answer 10

Answer 11

[AI-generated answer — Bot GPT 3.5]

I apologize for the mistake in the previous response.

To correctly solve -84 - (-5/6), we can simplify the expression using the rules of adding and subtracting negative numbers and fractions.

First, remember that subtracting a negative number is the same as adding a positive number. So, we can rewrite the expression as follows:

-84 + 5/6

Now, let's find a common denominator between -84 and 5/6, which is 6. To do this, we multiply the numerator and denominator of 5/6 by 6:

-84 + (5/6 * 6/6)
-84 + 30/6

Next, let's convert -84 to a fraction with a denominator of 6:

(-84 * 6/6) + 30/6
-504/6 + 30/6

Now that we have a common denominator, we can sum the numerators:

(-504 + 30)/6
-474/6

Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 6:

-474/6 = -79/1

Therefore, -84 - (-5/6) equals -79/1 or simply -79.

Answer 12

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 13

[AI-generated answer — Bot GPT 3.5]

To find the elevation at the bottom of Lake Segundo, we need to take into account that both lakes have depths below sea level. The elevation at the bottom of Lake Segundo would be the negative value of its depth.

Given that Lake Segundo has a depth of 56 feet and the elevation below sea level is considered negative, the elevation at the bottom of Lake Segundo would be -56 feet.

Answer 14

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 15

[AI-generated answer — Bot GPT 3.5]

To find the elevation at the bottom of Lake Segundo, we need to calculate 5/6 of the depth of Lake Profondo and then change the sign to represent that it is below sea level.

First, let's find 5/6 of the depth of Lake Profondo:

(5/6) * 84 = 70

Lake Segundo is 70 feet deep.

Now, let's account for the fact that the elevation is below sea level. We multiply the depth by -1 to change its sign:

-1 * 70 = -70

Therefore, the elevation at the bottom of Lake Segundo is -70 feet, indicating that it is 70 feet below sea level.

Answer 26

What is 4.65 converted to a fraction? The answer should be given in simplest form.

Answer 27

[AI-generated answer — Bot GPT 3.5]

To convert 4.65 into a fraction, we need to determine the fractional representation of the decimal.

Step 1: Write down the decimal as a fraction with the decimal value as the numerator and 1 as the denominator.

4.65/1

Step 2: Multiply both the numerator and denominator by 100 to eliminate the decimal.

4.65/1 * 100/100 = 465/100

Step 3: Simplify the fraction to its simplest form by finding the greatest common divisor (GCD) of the numerator and denominator, and then divide both by the GCD.

GCD(465, 100) = 5

Dividing both the numerator and denominator by 5:
465/5 = 93
100/5 = 20

Therefore, 4.65 converted to a fraction in simplest form is 93/20.

Answer 29

[AI-generated answer — Bot GPT 3.5]

To convert 4.65 to a fraction, we can follow these steps:

1. The whole number part of the decimal is 4.
2. The decimal part, 0.65, can be expressed as a fraction by placing the decimal value as the numerator and a power of 10 as the denominator.
0.65 = 65/100
3. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 5.
65/5 = 13
100/5 = 20

Therefore, 4.65 can be expressed as the fraction 4 13/20 in simplest form.

Answer 30

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

Answer 31

[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, we find that the rate of change in the plane's altitude is approximately 1142.86 feet per minute, rounded to the nearest hundredth.

Therefore, the rate of change in the plane's altitude is approximately 1142.86 feet per minute (descending).

Answer 32

Question 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?

Answer 33

[AI-generated answer — Bot GPT 3.5]

To find the change in the amount of water in gallons per minute, we can divide the change in water (250 gallons) by the time it takes to remove that amount (5 minutes):

Change in water per minute = Change in water / Time

Change in water per minute = 250 gallons / 5 minutes

The calculation gives us a rate of 50 gallons per minute.

Therefore, the change in the amount of water in gallons per minute is 50 gallons.

Answer 34

se the properties of operations and rules for multiplying and dividing signed numbers to solve: (−4)×(7/5)×(−3/4)÷(7/15)

Answer 35

[AI-generated answer — Bot GPT 3.5]

To solve the expression (-4) × (7/5) × (-3/4) ÷ (7/15) using the properties of operations and rules for multiplying and dividing signed numbers, follow these steps:

Step 1: Simplify the multiplication:

(-4) × (7/5) × (-3/4) = (-4) × (-3) × (7/5) × (1/4) = 12 × 7/5 × 1/4

Step 2: Simplify the division:

(12 × 7/5 × 1/4) ÷ (7/15) = (12 × 7 × 1/5 × 1/4) ÷ (7/15) = 84/20 ÷ 7/15

Step 3: Invert the divisor and multiply:

84/20 ÷ 7/15 = 84/20 × 15/7

Step 4: Divide to get the final result:

84/20 × 15/7 = (84 × 15) / (20 × 7) = 1260 / 140 = 9

Therefore, (-4) × (7/5) × (-3/4) ÷ (7/15) equals 9.

Answer 36

how did you get 1/4

Answer 37

[AI-generated answer — Bot GPT 3.5]

Apologies for the confusion in the previous response.

The correct calculations are as follows:

(-4) × (7/5) × (-3/4) ÷ (7/15)

Step 1: Simplify the multiplication:

(-4) × (7/5) × (-3/4) = (28/5) × (-3/4)

Step 2: Simplify the division:

(28/5) × (-3/4) ÷ (7/15) = (28/5) × (-3/4) × (15/7)

Now, let's simplify further:

= (28 × -3 × 15) / (5 × 4 × 7)

= (-1260) / (140)

= -9

Therefore, (-4) × (7/5) × (-3/4) ÷ (7/15) equals -9.

Answer 38

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 39

[AI-generated answer — Bot GPT 3.5]

To find out how long it will take for the fish to reach a depth of -37.8 meters, we can use the given information that the fish descends 1.5 meters every 2 minutes.

First, let's calculate the change in depth the fish needs to reach -37.8 meters from -10.8 meters:

Change in depth = Target depth - Initial depth
Change in depth = (-37.8) - (-10.8)
Change in depth = -37.8 + 10.8
Change in depth = -27

Now, let's determine how many intervals of 2 minutes it will take for the fish to descend 27 meters (rounded to the nearest interval):

Number of intervals = Change in depth / Rate of descent
Number of intervals = -27 / 1.5
Number of intervals ≈ -18

Since the fish descends 1.5 meters every 2 minutes, it will take approximately 18 intervals of 2 minutes for the fish to reach a depth of -37.8 meters.

Therefore, it will take the fish approximately 36 minutes (-18 intervals x 2 minutes per interval) to reach a depth of -37.8 meters.

This means that the fish will be swimming downward, descending into deeper depths for about 36 minutes until it reaches a depth of -37.8 meters, or 37.8 meters below sea level.
