Answers
68% of the data falls between one standard deviation from the mean which is 13.2 and 19.6
What is an equation?An equation is an expression composed of variables and numbers linked together by mathematical operations.
The empirical rule states that 68% of the data falls within one standard deviation, 95% within two standard deviation from the mean and 99.7% falls within three standard deviation from the mean.
Given a mean of 16.4 and a standard deviation of 3.2.
68% of the data falls one standard deviation from the mean = 16.4 ± 3.2 = (13.2, 19.6)

It will take you t seconds to carry the water, which you will do y times a day. What is the total amount of
time you will be carrying water?
How many hours would you spend carrying water in a year?
Answers
Answer:
To find the total amount of time you will be carrying water, we can use the following formula : Total time = t x y (t represents the time taken to carry water in seconds and y represents the number of times you will carry water per day)To find how many hours you would spend carrying water in a year, we can use the following formula:Total hours = (total time in seconds) / (3600 seconds in an hour)
Note: Remember to convert the result from seconds to hours.
It's important to mention that you need to know the value of t and y to be able to calculate the total time and the total hours.
If you have the values, you can substitute them in the equations above and get the answer.
Please help, i know you have to use pythagoras and the hypotenuse is 8.44 but i dont know how to get one of the sides
Answers
======================================================
Explanation:
Check out the diagram below.
I've defined the following points:
A = center of the circle, and center of the squareB, C, D, and E = vertices of the square that are on the circleF = midpoint of segment CDNow focus on triangle ACF. This is an isosceles right triangle with legs of 0.5x each. The hypotenuse is the radius of the circle. Let R be that unknown radius.
The area of the circle is given to us. It is 56 square cm. Use this to find the value of R.
[tex]A = \pi*(\text{radius})^2\\\\56 = \pi*R^2\\\\R^2 = 56/\pi\\\\R = \sqrt{56/\pi}\\\\R = 4.22200825\\\\[/tex]
This value is approximate. I used the calculator's stored version of pi to get the most accuracy possible.
------------
We now know the hypotenuse of triangle ACF.
Use Pythagoras (aka Pythagorean Theorem) to have the following steps:
[tex]a^2+b^2 = c^2\\\\(0.5\text{x})^2+(0.5\text{x})^2 = 4.22200825^2\\\\0.25\text{x}^2+0.25\text{x}^2 = 17.82535366\\\\0.5\text{x}^2 = 17.82535366\\\\\text{x}^2 = 17.82535366/0.5\\\\\text{x}^2 = 35.65070732\\\\\text{x} = \sqrt{35.65070732}\\\\\text{x} = 5.97082132708726\\\\\text{x} = 5.97\\\\[/tex]
The final answer is 5.97With the exception of 0.5 and 0.25, each decimal value mentioned is approximate.
Keep in mind that rounding to 3 sig figs means that we're rounding to 2 decimal places. The units digit is 1 sig fig, and the 2 decimal places give a total of 1+2 = 3 sig figs.
In short, we're rounding to the nearest hundredth.
--------------------
Check:
x = 5.97 is the square's side length.
It divides in half to get x/2 = 5.97/2 = 2.985 which gives each leg of triangle ACF.
Use a = 2.985 and b = 2.985 in the Pythagorean Theorem to find that c = 4.22142748 approximately. This is the approximate radius of the circle.
Use that radius to find the area of the circle.
A = pi*r^2
A = pi*(4.22142748)^2
A = 55.984594705958
A = 56.0
I'm rounding the area to 3 sig figs to keep consistent with the rounding done to x. We arrive at the circle area of 56 square cm, which helps confirm the answer is correct.
one person drives 70,000 miles in a car that averages 30 miles per gallon (mpg). how much gasoline are they using?
Answers
The person is using approximately 2,333.333 gallons of gasoline.
The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.
To calculate the amount of gasoline used, you can use the formula:
gasoline used = total miles driven / mpg
Where total miles driven is 70,000 miles and mpg is 30.
Plugging these values into the formula, we get:
Gasoline used = 70,000 miles / 30 mpg = 2,333.333 gallons
So the person is using approximately 2,333.333 gallons of gasoline.

(5h^2 + 3k) + (25h^4 + 15 h^2k + 9k^2)
(5h^2 + 3k)^3
Answers
The correct option is Option A: (5h^2)^3 + (3k)^3
The total number of cubic units that the cube totally occupies is the definition of a cube's volume. A cube is a solid three-dimensional object with six square faces. Volume is simply the total amount of space an object takes up. A thing with a bigger volume would take up more room.
Total Volume = V₁ + V₂
V₁ = Volume of Cube 1
V₂ = Volume of Cube 2
Volume of Cube = (Side Length)³
V₁ = (5h²)³
V₂ = (3k)³
∴ Total Volume = (5h²)³ + (3k)³
And this cannot be simplified further.
Therefore, the correct option is Option A: (5h^2)^3 + (3k)^3

In order to write an equation of the line in slope-intercept form, we first have to look at the equation:
y = mx + b
We know that m represents slope, and b represents the y-intecept, in other words, what y is equal to when x is equal to zero.
We already have y and x, (4,5), and the slope of the line, since the two lines are parellel, they share the same slope. So now, we have to pulg those values into the equation and solve for b:
(4,5)
y = 5
x = 4
m = -2
y = mx + b
(5) = (-2)(4) + b
5 = -8 + b
13 = b
So, equation of the line in slope-intercept form that passes through point (4, 5), is y = -2x + 13
Remeber that you can always graph to check your work!
I hope this helps! :)
angelina spent $23.65 on books and magazines when she went to chapters. She bought a total of 7 items. The books cost $5.95 each and the magazine cost $2.95 each. How many books and magazines did angelina buy
Answers
In all, she purchased 1 book and 6 periodicals, taking into account the inequality.
What is inequality?
In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given, Angelina spent $23.65 on books and magazines when she went to chapters. She bought a total of 7 items. The books cost $5.95 each and the magazine cost $2.95 each.
Let "b" be the number of total book and "m" be the number of magazine she bought.
Inequality from the given data
m + b = 7
since, Angelina spent $23.65 on books and magazines
thus,
5.95 * b + 2.95 * m = 23.65
from equation 1
5.95b + 2.95(7 - b) = 23.65
5.95b + 20.65 - 2.95b = 23.65
3 b = 3
b = 1
from any equation
m = 6
Therefore, she total bought 1 book and 6 magazines according the given inequality.

Find an equation for a line passing through (10,10) that is perpendicular to the line with equation 5x+8y=-9. Write your equation in
Answers
The equation of a line passing through (10,10) that is perpendicular to the line with equation 5x + 8y = -9 is y - 10 = (8/5)(x - 10) or y = (8/5)x - 6.
Get the slope of the line 5x + 8y = -9 by rewriting it in slope-intercept form. Subtract 5x from both sides and divide by 8.
y = (-5/8)x - (9/8)
The slope of this line is -5/8. The negative reciprocal of -5/8 is 8/5. Therefore, the slope of the line that is perpendicular to 5x + 8y = -9 is 8/5.
Using point-slope form, determine the equation of the line.
y - y₁ = m(x - x₁)
y - 10 = (8/5)(x - 10)
or using the slope-intercept form,
y = mx + b
y = (8/5)x + b
10 = (8/5)10 + b
b = -6
y = (8/5)x - 6

Jerome has $3,000 to invest in an account that yields 2.1% annual interest which is compounded quarterly. If he leaves the money untouched in the account for 4 years, how much money will he have?
Answers
Jerome will have $3261.93 after 4 years
How to calculate how much money Jerome will have?
The formula for compound interest is A = P(1 + r/n)^(nt)
where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for.
In this case, P = $3,000, n = 3, r = 2.1% = 0.021, t = 4 years. Thus:
A = P(1 + r/n)^(nt)
A = 3000(1 + 0.021/3)^(3×4)
A = 3000(1 + 0.021/3)^(12)
A = $3261.93
