2. Sara discarded 1/10 : of the 200 apples she picked as defective. The rest were sold as fresh fruit. How many apples picked were sold as fresh fruit? (1 point)
To find out how many apples were sold as fresh fruit, we need to subtract the number of discarded apples from the total number of apples picked.
Sara discarded 1/10 of the 200 apples, which means she discarded (1/10) * 200 = 20 apples.
Therefore, the number of apples picked and sold as fresh fruit is 200 - 20 = 180 apples.
Is that true?
Apologies for the miscalculation.
If Sara discarded 1/10 of the 200 apples she picked, she would have discarded (1/10) * 200 = 20 apples.
Therefore, the number of apples that were sold as fresh fruit is 200 - 20 = 180 apples.
The town of Oak Manor measures 3.8 miles by 4.2 miles. Solve for the total area.
Hint: Use the formula for the area of a rectangle = length x width.
To calculate the total area of Oak Manor, we can use the formula for the area of a rectangle, which is length multiplied by the width.
Given that the length of Oak Manor is 3.8 miles and the width is 4.2 miles, we can plug these values into the formula:
Area = Length x Width
Area = 3.8 miles x 4.2 miles
Area = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 square miles.
To find out how tall the basketball player's son is, we need to multiply the basketball player's height by 1/4.
The basketball player is 6 2/3 feet tall. To convert this mixed number into an improper fraction, we can multiply the whole number (6) by the denominator (3) and add the numerator (2). Then, we place the result over the denominator:
6 2/3 = (6 * 3 + 2) / 3 = 20/3
Now, we'll multiply 20/3 by 1/4 to find the height of the son:
Height of the son = (20/3) * (1/4)
Multiplying the numerators and denominators, we get:
Height of the son = (20 * 1) / (3 * 4) = 20/12
Simplifying the fraction, we divide both the numerator and denominator by the greatest common divisor, which is 4:
Height of the son = 5/3
Therefore, the son of the basketball player is 5/3 feet tall.
A diver descends at a rate of 8 m/min. Which expression CANNOT be used to find her depth after 5 minutes?
To find the diver's depth after 5 minutes, we need to multiply the rate of descent (8 m/min) by the number of minutes (5).
The expression that cannot be used to find her depth after 5 minutes would be the one that does not multiply the rate of descent by the number of minutes.
Let's look at the options:
a) 8 m/min * 5 min = 40 m
b) (8 m)(5 min) = 40 m
c) 8 m + (5 min) = This expression does not multiply the two quantities together and is therefore the expression that cannot be used to find the diver's depth after 5 minutes.
So, the expression that cannot be used to find her depth after 5 minutes is c) 8 m + (5 min).
In September, a sporting goods store offers a kayak for $378. Over the next four months, the store reduced the price of the kayak $15 each month. What is the price of the kayak at the end of four months?(1 point)
To find the price of the kayak at the end of four months, we need to subtract $15 from the initial price for each month.
Starting with the initial price of $378:
After the first month, the price will be $378 - $15 = $363.
After the second month, the price will be $363 - $15 = $348.
After the third month, the price will be $348 - $15 = $333.
After the fourth (and final) month, the price will be $333 - $15 = $318.
Therefore, the price of the kayak at the end of four months will be $318.
so does anyone know the right answers
Apologies for the incorrect response. Let's go through the calculation again.
Starting with the initial price of $378:
The price is reduced by $15 each month for four months:
$378 - $15 = $363
$363 - $15 = $348
$348 - $15 = $333
$333 - $15 = $318
Therefore, the price of the kayak at the end of four months is $318.

2. Sara discarded 1/10 of the 200 apples she picked as defective. The rest were sold as fresh fruit. How many apples picked were sold as fresh fruit?
To find the number of apples sold as fresh fruit, we need to subtract the number of discarded apples from the total number of apples picked.
Sara discarded 1/10 of the 200 apples, which means she discarded (1/10) * 200 = 20 apples.
Therefore, the number of apples picked and sold as fresh fruit is 200 - 20 = 180 apples.
3. A basketball player is 6 2/3 feet tall. His infant son is 1/4 as tall. How tall is his son?
To find the height of the basketball player's son, we multiply the basketball player's height by 1/4.
The basketball player's height is 6 2/3 feet, which can be converted to an improper fraction as 20/3 feet.
Multiplying 20/3 by 1/4 gives (20/3) * (1/4) = 20/12 = 5/3 feet.
Therefore, the basketball player's son is 5/3 feet tall.
4. In September, a sporting goods store offers a kayak for $378. Over the next four months, the store reduced the price of the kayak by $15 each month. What is the price of the kayak at the end of four months?
Starting with the initial price of $378, we subtract $15 from the price for each of the four months.
$378 - $15 = $363
$363 - $15 = $348
$348 - $15 = $333
$333 - $15 = $318
Therefore, the price of the kayak at the end of four months is $318.
I apologize for any previous errors and thank you for your patience.

To find the height of the basketball player's son, we multiply the basketball player's height by 1/4.
The basketball player's height is 6 2/3 feet. We can convert this mixed number into an improper fraction by multiplying the whole number (6) by the denominator (3) and adding the numerator (2). Then, place the result over the denominator:
6 2/3 = (6 * 3 + 2) / 3 = 20/3
Next, we'll multiply 20/3 by 1/4 to find the height of the son:
Height of the son = (20/3) * (1/4)
When multiplying fractions, we multiply the numerators together and the denominators together:
Height of the son = (20 * 1) / (3 * 4) = 20/12
We can simplify the fraction by dividing both the numerator and denominator by the greatest common divisor, which is 4:
Height of the son = 5/3
Therefore, the son of the basketball player is 5/3 feet tall.
wrong
Apologies for the incorrect response. Let's reevaluate the question.
The basketball player's height is 6 2/3 feet.
To find the height of his son, who is 1/4 as tall, we can multiply the basketball player's height by 1/4.
Let's convert the basketball player's height to an improper fraction: 6 2/3 = (6 * 3 + 2)/3 = 20/3.
Now, we'll multiply 20/3 by 1/4 to find the son's height:
(20/3) * (1/4) = (20 * 1) / (3 * 4) = 20/12.
Simplifying the fraction, we can divide both the numerator and denominator by the greatest common divisor, which is 4:
20/12 = 5/3.
Therefore, the son of the basketball player is 5/3 feet tall.

A diver searches for a sunken treasure that is 97.2 feet below the surface. What is the diver’s elevation when he is 2/3

To find the diver's elevation when he is 2/3 of the way down, we need to calculate 2/3 of the distance he must descend, which is 97.2 feet.
2/3 of 97.2 feet = (2/3) * 97.2 feet
Multiplying the numerator and the denominator, we get:
2/3 * 97.2 = 64.8 feet
Therefore, the diver's elevation when he is 2/3 of the way down is -64.8 ft.

−8(5)
To find the diver's depth after 5 minutes, we need to multiply the rate of descent (8 m/min) by the number of minutes (5).
Now let's go through the options to determine which expression cannot be used to find the depth:
−8−8−8−8−8: This expression represents subtracting 8 from itself repeatedly, which results in -40. This can be used to find the depth after 5 minutes.
−85: This expression represents -8 divided by 5, which results in -1.6. This can be used to find the depth after 5 minutes.
−8+(−8)+(−8)+(−8)+(−8): This expression represents adding negative 8 five times, which results in -40. This can be used to find the depth after 5 minutes.
−8(5): This expression represents multiplying -8 by 5, which results in -40. This can also be used to find the depth after 5 minutes.
Therefore, all the given expressions can be used to find the diver's depth after 5 minutes.
I'm sorry, -85 is really −8/5
Apologies for the confusion. You are correct.
The expression -85 should be read as -8/5, which represents -8 divided by 5.
Hence, the expression −8−8−8−8−8, −8+(−8)+(−8)+(−8)+(−8), and −8(5) can all be used to find the diver's depth after 5 minutes.
Therefore, the expression that CANNOT be used to find the diver's depth after 5 minutes is −85 (which should be read as −8/5).
the actual expression is
