The athlete drink 16 ounces of water every two hours starting at 7:30 AM and continuing for the next 14 hours. A) how many quarts did the athlete consume? B) how many pints of water did the athlete consume?
When the athlete drink 16 ounces of water every two hours for the next 14 hours,
(A) The athlete consumes 3.5 quartz of water.
(B) The athlete consumes 7 pints of water.
Conversions(1) Ounce to Pints16 ounces = 1 pint
(2) Quarts to Ounces1 quart = 32 ounces.
(A) Calculation for the water consumed by athlete in quarts:The total duration for which athlete consumes the water is 14 hours with a after every 2 hours.
The total number of times the water consumed by athlete is 14/2 = 7.
Covert the 16 ounces of water in quarts
= 16/ 32
=1/2
The total quantity of water consumed in quarts is
= 7×(1/2)
= 3.5 quarts
Thus, the amount of water consumed by athlete in entire 14 hours is 3.5 quarts.
(B) Calculation for the water consumed by athlete in pints:The total duration for which athlete consumes the water is 14 hours with a after every 2 hours.
The total number of times the water consumed by athlete is 14/2 = 7.
Convert 16 ounce of water into pint
= 16/16
= 1
The total quantity of water consumed in pints is
= 7×1
= 7
Thus, the amount of water consumed by athlete in entire 14 hours is 7 pints.

A cart rolls 2 m to the right then rolls back 1 m to the left.
What is the displacement of the cart from the initial to the final positions?
HELP PLEASE
Answer:
3 m is the displacement
Step-by-step explanation:
because the distance traveled is how much you really move necessarily is the distance from where you started to where you ended in a sraight line, not every single move you made, and the displacement is how much you moved altogether in any and every direction even if you went in circles. hope this helps!! love yawl, stay safe!! <3 <3 <3 <3 <3 <3 <3
The displacement of the cart will be "3 m".
Towards the right,
The distance covered by the cart is:
= 2 m
Towards the left,
The distance covered:

Find the endpoint of the line segment with the given endpoint and midpoint.
Answer:
(10, 2)
Step-by-step explanation:
To get from the given endpoint to the midpoint, 6 was added to x and 2 was added to y. As per the definition of a midpoint, the resulting two line segments will be congruent (first endpoint and midpoint congruent to midpoint and second endpoint). Use the same formula (x + 6, y + 2) to find the second endpoint (use the x and y of the midpoint):

A circle is drawn to represent a pizza with a 12-inch diameter. The circle is cut into eight congruent pieces. What is the length of any one piece of this circle?
Answer:
6 inch
Step-by-step explanation:
half the diameter to find the length
The outer edge length of one piece of the cut circle is 3π / 2 inches
Diameter of a circle
The diameter of a circle is a line that passes through the centre and meets the circumference at opposite ends.
The circle representing the pizza is 12 inches in diameter. The radius is half of the diameter. Therefore,
radius = 12 × 0.5 = 6 inches
The circle is cut into 8 congruent pieces. The length of the outer edges of any one piece of the circle can be calculated as follows;
circumference of the circle = 2πr
circumference of the circle = 2 × π × 6 = 12π inches
Now let's divide it into 8 part.
edge length of one piece of the circle = 12π / 8 = 3π / 2

A rectangular prism has a length of 6 cm, a width of 3 cm, and a height of 412cm.
The prism is filled with cubes that have edge lengths of 12 cm.
How many cubes are needed to fill the rectangular prism?
Enter your answer in the box.
To fill the rectangular prism,
cubes are needed.
Answer: To fill the rectangular prism, 4 cubes are needed.
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of the prism and divide it by the volume of one cube:
Volume of a rectangular prism = Length x width x height
V P = 6x3x412 = 7,416 cm3
Volume of a cube = side length^3
VC = 12^3 = 1,728 cm3
Finally;
Volume of the prism / volume of one cube = 7,416 /1,728 = 4.29 = 4 cubes

Math scores on the SAT exam are normally distributed with a mean of 514 and a standard deviation of 118. If a recent test-taker is selected at random, what is the probability the student scored 573 or greater on the exam?
Answer: the probability that the student scored 573 or greater on the exam is 0.31
Step-by-step explanation:
Let x be the random variable representing the math scores on the SAT exam. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 514
σ = 118
the probability that the student scored 573 or greater on the exam is expressed as
P(x > 573) = 1 - P(x ≤ 573
For x = 573,
z = (573 - 514)/118 = 0.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.69
P(x > 573) = 1 - 0.69 = 0.31

[tex]8x-x=1-6[/tex]

[tex]x=\frac{-5}{7}[/tex]
Answer:
x = -5/7
Step-by-step explanation:
2(4x+3)=x+1
Distribute
8x +6 = x+1
Subtract x from each side
8x+6-x = x+1-x
7x+6 = 1
Subtract 6 from each side
7x+6-6 = 1-6
7x =-5
Divide each side by 7
7x/7 = -5/7
x = -5/7
Josh paid for four books with three $20 bills he received $12 in change each book was the same price how much did each book cost
Three $20 bills is a total of $60
$60 - $12 = $48
He spent a total of $48 on the books
Divide the total spent by the number of books:
48 / 3 = 16
Each book cost $16
Answer:$12 per book
Step-by-step explanation: $20 x 3= $60
If you have $12 change you minus that from the $60
Now that is $48 for 4 books.
To work out one book you do $48/4 which is $12 per book.

Which of the following rational functions is graphed below?
Answer:
option B
Step-by-step explanation:
We can see in the graph that the function has two values of x where the value of y goes to infinity: x = -6 and x = 6.
These points where the value of the function goes to infinity usually are roots of the polynomial in the denominator of a fraction (when the values of x tend to these values, the denominator of the fraction tends to 0, so we have a discontinuity in the function).
So the option that represents a function that have these points in x = -6 and x = 6 is the function in option B.
The other options show functions that have only one point that goes to infinity.

Calculate the mean given the frequency table
Class
Frequency

24
10-19
20
20-29
32
Answer:
15.6
Step-by-step explanation:
First, multiply the midpoint of each class by its frequency, as follows:
Class midpoint frequency midpoint*frequency
0-9 4.5 24 4.5*24 = 108
10-19 14.5 20 14.5*20 = 290
20-29 24.5 32 24.5*32 = 784
Total 76 1182
The mean is computed as the division between the addition of the "midpoint*frequency" column by the addition of "frequency" column.
mean = 1182/76 ≈ 15.6

100pts: What is the slope of the following curve at x = n, for an arbitrarily chosen integer n?:
y = 3x^2 - 37x + 6
Answer:
6n -37
Step-by-step explanation:
The slope would be the derivative of the function
dy/dx = 6x - 37 evaluated at the point n
dy/dx = 6n -37
Answer:
6n - 37
Step-by-step explanation:
The derivative of the function f(x) gives the gradient (slope) of the tangent to the graph of y = f(x) at the point (x, y).
Given:
[tex]y=3x^2-37x+6[/tex]
Therefore, the gradient (slope) of the given curve at x is:
[tex]\implies \dfrac{dy}{dx}=2 \cdot 3x^{2-1}-37x^{1-1}+0[/tex]
[tex]\implies \dfrac{dy}{dx}=6x-37[/tex]
To find the slope, simply substitute x for n:
[tex]\implies 6n-37[/tex]
