Answer:
13 miles
Step-by-step explanation:
The shortest distance would be a straight line between the two points. This would be a hypotenuse of a right triangle
We can use the Pythagorean theorem to determine the length
a^2+b^2=c^2
5^2 +12^2 = c^2
25+144= c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)
13 = c

8.5 milessssssss and aaaaaa

Weight of a rock: In a geology course, students are learning to use a balance scale to accurately weigh rocks. One student plans to weigh a rock 20 times and then calculate the average of the 20 measurements to estimate her rock's true weight. A second student plans to weigh a rock 5 times and calculate the average of the 5 measurements to estimate his rock's true weight. Suppose the students construct a 95% confidence interval for the true weight of their rocks. Whose interval do you expect to be more precise (narrower)
Answers
Answer:
The first student, with 20 measurements, will have the more precise interval due to the larger sample size.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
[tex]M = z\frac{s}{\sqrt{n}}[/tex]
In which z is related to the confidence level, s to the standard deviation and n to the sample size.
The margin of error is inversely proportional to the square root of the sample size, which means that a larger sample will lead to a lower margin of error, that is, to a more precise interval.
In this question:
One student will use 5 measurements, other 20. The first student, with 20 measurements, will have the more precise interval due to the larger sample size.

Find the circumference of the given circle.
Use 3.14 as an approximation of Pi.
Answers
Answer:
Step-by-step explanation:
circumference=2*pie*r
=2*3.14*7
=43.96 in.
========================================================
Work Shown:
C = 2*pi*r
C = 2*3.14*7
C = 43.96 inches is the approximate circumference, aka the distance around the circle.
Use more decimal digits in pi to get a more accurate circumference.

y=x-4
y=6x-10
Answers
Step-by-step explanation:
put 6x-10 in y=x-4
so
y = (6x-10) - 4
y = 6x-14
equation form: x=6/5 y= -14/5
to solve, set the equations equal to each other so it’s x-4=6x-10 which gives you x
then plug x into one of the equations so y=6/5-4 which gives you y=-14/5
hope this helps!
Which linear function has a y-intercept of -5?
Answers
Answer: Upper right corner (northeast corner)
x-3y = 15
===================================================
Explanation:
The y intercept always occurs when x = 0.
If we plug x = 0 into 2x+y = -10 (northwest corner), then we solve for y to get...
2x+y = -10
2(0)+y = -10
0+y = -10
y = -10
We see that the y intercept here is -10, but we want -5 instead. So we can rule this out.
In the northeast corner, plugging x = 0 leads to,
x-3y = 15
0-3y = 15
-3y = 15
y = 15/(-3)
y = -5
We get the correct y intercept we're after. So we can stop here.
If you plugged x = 0 into the equation of the southwest corner, you'll get y = 5 which is fairly close but not quite what we want. The southeast corner equation leads to a y intercept of y = 5 as well.
Answer:
x - 3y = 15
Step-by-step explanation:
x - 3y = 15
-3y = -x + 15
y = 1/3x - 5
-5 is the y-intercept.

To the nearest hundredth, what is the circumference of a circle with a radius
of 7 units?
A. 43.98 units
B. 21.99 units
C. 35.75 units
D. 153.94 units
Answers
Answer:
43.98
Step-by-step explanation:
The circumference of a circle with a radius of 7 units is approximately 43.98 units, which corresponds to option A.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
Given that the radius of the circle is 7 units, we can substitute this value into the formula:
To find the circumference of a circle, we can use the formula C = 2πr, where C represents the circumference and r represents the radius.
C = 2π(7) = 14π
Use the approximation π ≈ 3.14:
C ≈ 14(3.14) = 43.96
Rounding this value to the nearest hundredth, we get approximately 43.98 units.
Therefore, the circumference of a circle with a radius of 7 units is approximately 43.98 units.

Answer:
[tex]\frac{3x^3z^5}{5y}[/tex] ( [tex]\frac{20y^3}{x^2z^6}[/tex])
Step-by-step explanation:
When given the following equation,
[tex]\frac{3x^3z^5}{5y}[/tex] ÷ [tex]\frac{x^2z^6}{20y^3}[/tex]
The first step is to convert the equation into a form that can be solved, in essence dividing any number by a fraction is the same as multiplying that number by the reciprocal of the fraction. The reciprocal of a fraction is when one switches the position of the numerator and denominator, the numerator is the number on top of the fraction, and the denominator is the number underneath the fraction.
[tex]\frac{3x^3z^5}{5y}[/tex] ÷ [tex]\frac{x^2z^6}{20y^3}[/tex]
[tex]\frac{3x^3z^5}{5y}[/tex] * [tex]\frac{20y^3}{x^2z^6}[/tex]
Simplify, reduce the numbers that are found in common between the numerator and denominator,
[tex]\frac{3x^3z^5}{5y}[/tex] * [tex]\frac{20y^3}{x^2z^6}[/tex]
[tex]\frac{3x^3z^5*20y^3}{5y*x^2z^6}\\\\=\frac{3x*4y^2}{z}\\\\=\frac{12y^2x}{z}[/tex]

Rommel has 3 kilograms of potatoes and 4 kilogramsof onions. He plans to use 1.5 kilograms of potatoes and 880 grams of onions fora recipe. How many total kilograms of the produce will not be used?
Answers
Answer:
4.62 KG
Step-by-step explanation:
1000 grams = 1kg
3kg = 3000g
4 kg = 4000g
1.5 = 1500g
left over potatoes = 3000 - 1500 = 1500 g or 1.5kg
left over onions = 4000 - 880 = 3120 = 3.12kg
total kilos not used = 1.5 + 3.12 = 4.62

Answers
Answer:
x = [tex]\frac{1}{2}[/tex] , x = 1
Step-by-step explanation:
Given
[tex]\frac{2x}{x+3}[/tex] + [tex]\frac{3}{x-3}[/tex] = [tex]\frac{8}{x^2-9}[/tex] ← denominator is a difference of squares
[tex]\frac{2x}{x+3}[/tex] + [tex]\frac{3}{x-3}[/tex] = [tex]\frac{8}{(x+3)(x-3)}[/tex]
Multiply through by (x + 3)(x - 3) to clear the fractions
2x(x - 3) + 3(x + 3) = 8 ← distribute left side and simplify
2x² - 6x + 3x + 9 = 8
2x² - 3x + 9 = 8 ( subtract 8 from both sides )
2x² - 3x + 1 = 0 ← in standard form
(2x - 1)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
x - 1 = 0 ⇒ x = 1

Answers
Answer:
x = -[tex]\frac{2}{3}[/tex]
y = 2
Step-by-step explanation:
The process of elimination is a method of solving a system of equations. One must first manipulate one of the equations such that one of the variables shared between the two equations has the inverse coefficient of the same variable in the other equation. Therefore, when one adds the equations, the variable cancels. One can solve for the variable using inverse operations, and then backsolve to find the value of the first variable.
When given the following system:
y = 3x + 4
y + 6x = 3x
Use inverse operations so that both equations are solve for one variable,
y = 3x + 4
y = -3x
Add the systems so that one of the variables (x) cancels, this process is called the process of elimination;
y = 3x + 4
y = -3x
_________
2y = 4
Inverse operations,
2y = 4
y = 2
Now backsolve, find the value of (x) by substituting the value of (y) into the equation:
y = -3x
2 = -3x
x = -[tex]\frac{2}{3}[/tex]
