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
what is the anwer
The answer is $\boxed{\frac{2}{15}}$.
Let's say there are g gray cars in total and e electric cars among them. Then, we have two equations: (1) g = (2/5) total number of cars, and (2) e = (1/3) g. <<1/3*2/5=2/15>>2/15 of the cars are both gray and electrically powered. Answer: \boxed{\frac{2}{15}}.

Apologies for the confusion. The answer in simplified fraction form is $\frac{2}{15}$.
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.)(1 point)
Lake Segundo is 5/6 as deep as Lake Profondo.
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
Simplifying the expression, we have:
Depth of Lake Segundo = (5 * 84) / 6 feet
Depth of Lake Segundo = 420 / 6 feet
Depth of Lake Segundo = 70 feet
Since the elevation is below sea level, the elevation at the bottom of Lake Segundo is -70 feet.
Therefore, the elevation at the bottom of Lake Segundo is \boxed{-70}.
are you sure
Apologies, I made a mistake in my previous response.
Given that Lake Segundo is 5/6 as deep as Lake Profondo:
Depth of Lake Segundo = (5/6) * 84 feet
Depth of Lake Segundo = (5 * 84) / 6 feet
Depth of Lake Segundo = 420 / 6 feet
Depth of Lake Segundo = 70 feet
Since the elevation is below sea level, the elevation at the bottom of Lake Segundo is -70 feet.
Therefore, the correct answer is -70 feet.
What is the quotient of 100÷(−10)÷5?
To solve this, we follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
100 ÷ (-10) ÷ 5 can be rewritten as:
(100 ÷ -10) ÷ 5
Now let's solve the expression inside the parentheses:
100 ÷ -10 = -10
Now we have:
(-10) ÷ 5
Finally, we divide -10 by 5:
-10 ÷ 5 = -2
Therefore, the quotient of 100 ÷ (-10) ÷ 5 is -2.
What is the quotient of 842.4 ÷ −0.6?
To find the quotient of 842.4 ÷ (-0.6), we divide 842.4 by -0.6:
842.4 ÷ (-0.6) = -1404
Therefore, the quotient of 842.4 ÷ (-0.6) is -1404.
What is 4.65 converted to a fraction? The answer should be given in simplest form.(1 point)
To convert 4.65 to a fraction, we can write it as a fraction with the decimal value as the numerator and a power of 10 as the denominator.
4.65 = $\frac{4.65}{1}$
To simplify this fraction, we need to remove the decimal. We can do this by multiplying the numerator and denominator by 100 to remove the decimal places:
4.65 = $\frac{4.65 \times 100}{1 \times 100} = \frac{465}{100}$
Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 5:
$\frac{465}{100} = \frac{93 \times 5}{20 \times 5} = \frac{93}{20}$
Therefore, 4.65, when converted to a fraction in simplest form, is $\boxed{\frac{93}{20}}$.
wrong
I apologize for the mistake.
To convert 4.65 to a fraction, we can write it as a fraction with the decimal part as the numerator and a power of 10 as the denominator.
Since 4.65 has two decimal places, we can express it as:
4.65 = 4 + 0.65
To convert 0.65 to a fraction, we can express it as 65/100.
Therefore, 4.65 can be written as 4 + 65/100.
We can simplify the whole number part first by expressing it as an improper fraction:
4 = 4/1
Now, we have:
4 + 65/100 = 4/1 + 65/100
To add these fractions, we need a common denominator. The common denominator is 100:
4/1 + 65/100 = (4*100)/100 + 65/100
= 400/100 + 65/100
= 465/100
Therefore, 4.65, when converted to a fraction in simplest form, is $\boxed{\frac{465}{100}}$.

Apologies for the previous incorrect responses.
To convert 4.65 to a fraction, we need to consider the decimal places. Since 4.65 has two decimal places, we can write it as:
4.65 = 4 + 0.65
Now, let's convert 0.65 to a fraction. The decimal point is in the hundredths place, so we can write it as:
0.65 = 65/100
Therefore, 4.65 can be expressed as:
4 + 65/100
To add these fractions, we need a common denominator. The common denominator is 100:
4 + 65/100 = (4 * 100 + 65) / 100 = 465 / 100
Now let's simplify this fraction. Both the numerator and denominator can be divided by 5:
465 / 100 = (93 * 5) / (20 * 5) = 93/20
Therefore, 4.65, when converted to a fraction in simplest form, is $\boxed{\frac{93}{20}}$.
Use long division to convert 2 7/16 to a decimal
To convert 2 7/16 to a decimal using long division, we can set it up as follows:
_____
16 | 2.4375
We start by dividing 2 (the whole number) by 16:
16 does not divide into 2, so we bring down the 7:
_____
16 | 2.4375
- 0
Next, we bring down the next digit, which is 4, and add it to the previous result (0):
_____
16 | 2.4375
- 0
4
We then divide 16 into 43:
16 | 2.4375
- 0
40
- 32
Since 16 does not divide evenly into 43, we bring down the next digit, which is 7:
16 | 2.4375
- 0
40
- 32
75
We then divide 16 into 75:
16 | 2.4375
- 0
40
- 32
75
- 64
115
Again, since 16 does not divide evenly into 115, we bring down the next digit, which is 0:
16 | 2.4375
- 0
40
- 32
75
- 64
115
- 112
Finally, we bring down the last digit, which is 0:
16 | 2.4375
- 0
40
- 32
75
- 64
115
- 112
30
At this point, we can see that the division is complete with a remainder of 30.
Therefore, 2 7/16, when converted to a decimal using long division, is approximately 2.4375.

still wrong
Apologies for the confusion. Let's try it again.
To convert 6 7/15 to a decimal using long division, we can set it up as follows:
_____
15 | 6.4666...
We start by dividing 67 (the whole number part and the numerator of the fraction) by 15:
15 goes into 67 four times (4 × 15 = 60). Subtracting, we get 67 - 60 = 7.
Now, we bring down the 0 from the decimal part:
_____
15 | 6.4666...
- 4
20
Next, we add a zero decimal place and bring it down to the remainder:
_____
15 | 6.4666...
- 4
20
0
Then, we divide 150 into 200:
15 goes into 200 thirteen times (13 × 15 = 195). Subtracting, we get 200 - 195 = 5.
Finally, we bring down another zero:
_____
15 | 6.4666...

50
We can keep adding more zeros and performing more divisions, but we can already see that a pattern is emerging. The remainder keeps repeating as 50.
Therefore, 6 7/15, when converted to a decimal using long division, is approximately 6.4666..., with a repeating block of 6.
Therefore, 6 7/15 is approximately equal to 6.46.

Kimberly ran 4/5 of the way around the track before getting tired and slowing her pace. What percentage of the track did she run at a slower pace?(1 point)
If Kimberly ran 4/5 of the way around the track before slowing her pace, then the remaining 1/5 of the track is the distance she ran at a slower pace.
To find the percentage, we can convert 1/5 to a decimal by dividing 1 by 5:
1 ÷ 5 = 0.2
To convert this decimal to a percentage, we multiply it by 100:
0.2 * 100 = 20
Therefore, Kimberly ran at a slower pace for 20% of the track.
What is 90.5% written as a decimal?(1 point)
To write 90.5% as a decimal, we divide 90.5 by 100:

Therefore, 90.5% written as a decimal is 0.905.
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.
To find the rate of change in the plane's altitude, we divide the change in altitude (4,000 feet) by the time taken to make the adjustment (3.5 minutes).
Rate of change in altitude = Change in altitude / Time taken
Rate of change in altitude = 4,000 feet / 3.5 minutes
Dividing 4,000 feet by 3.5 minutes gives us approximately 1142.86 feet/minute. Rounding it to the nearest hundredth, the rate of change in the plane's altitude is 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.
