6. The rungs of a ladder are each perpendicular to one side of the ladder. What can you conclude about the rungs of the ladder? Justify your answer by stating the theorem you used.
Answer: You can conclude that the ladder rungs are parallel using the Parallel Transversal Theorem.
Step-by-step explanation: Picture a ladder, all of the rungs are horizontal, but the sides are vertical. So all of the rungs are perpendicular to the sides, making right angles. If all of the rungs make 90 degree angles to the sides, that means that all of the rungs are straight with no angle. This makes sure that the rungs will not hit each other, so they are parallel.
2 step equations: solve the equation below:
m/5+9=11
Answer:
m=10
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
m/5+9-(11)=0
m
Simplify —
5
m
(— + 9) - 11 = 0
5
Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
9 9 • 5
9 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
m + 9 • 5 m + 45
————————— = ——————
5 5
(m + 45)
———————— - 11 = 0
5
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
11 11 • 5
11 = —— = ——————
1 5
Adding up the two equivalent fractions
(m+45) - (11 • 5) m - 10
————————————————— = ——————
5 5
m - 10
—————— = 0
5
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-10
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-10 = 0
Solve : m-10 = 0
Add 10 to both sides of the equation :
m = 10
m = 10

It says my answer needs to be 20 characters long so I'm writing this.
write an equation that is parallel to the equation (-3,-5) and (1,7) and goes through the point (2,4)
You didn't give an original equation, just the two points so I'm just going to go ahead and assume that b = 0, but in reality, it doesn't really matter what it equals I think.
Slope intercept form:
First, we find the slope, so we do y1-y2/x1-x2 which is 3. So then we do y=mx+b so 4=3(2)+b. Then we do 4=6+b. So, b = -2.
So the equation is y=3x-2
Find the slope which we already know. Plug into y-y1=m(x-x1).
y-4=3(x-2)
y-4=3x+6

Actually Welcome to the Concept of the Mathematics, this is called as function inside another function, just we have replace the condition of x here,
1)g(f(4)) = here, f(4) = 4-7= -3
so now, g(-3) = (-3)^2 =9
g(f(4)) = 9
2) f(g(4)) = 16-7 = 9
f(g(4))= 9
3) g(f(-1)) = 64
4) f(g(-1)) = -6
done.
The quotient of a number and twelve is the sum of eight and the number.
Answer: n/12=8+n
Answer:
Step-by-step explanation:
12(n/12 = 8 + n)
n = 96 + 12n
-11n = 96
n = -96/11
Answer:
-96/11 or -8 8/11
Step-by-step explanation:
For this, create an equation, x/12=x+8.
Any number without a denominator has a denominator of 1, so x/12=(x+8)/1.
Now, cross multiply to get 1*x=12(x+8).
Simplify that to x=12x+96.
Subtract 12x from both sides, and you have -11x=96.
Divide by -11, and x=-96/11.
The function f(t) = |98.6-x|, represents a persons's variance from normal body temperature, where x represents a person's current body temperature in degrees Fahrenheit. Medical professionals say healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit.
Answer:
98.1°F ≤ x ≤ 99.1°F
Step-by-step explanation:
Given the function:
f(x) = |98.6 - x|
Variance = 0.5
98.6°F - x = ± 0.5
Lower bound :
98.6 - 0.5 ≤ x
98.1 ≤ x
Upper bound :
x ≤ 98.6 + 0.5
x ≤ 99.1
Hence,
98.1°F ≤ x ≤ 99.1°F
Ydia is having a party on Saturday. She decides to write a riddle on her invitations to describe her house number on Cypress Street. Use the clues below to find Lydia's address. My address is a 5−digit number. The tens digit is 6 less than 8. The thousands digit is twice the digit in the tens place. The hundreds digit is the greatest odd number that is less than 10. The ones digit is the product of 6 and 1. The ten thousands digit is the difference between the hundreds digit and the ones digit.
Answer:
Ydia's address is: 62943
Explanation
Represent the digit as ABCDE such that:
[tex]A = Ones[/tex]
[tex]B = Tens[/tex]
[tex]C = Hundred[/tex]
[tex]D = Thousand[/tex]
[tex]E = Ten\ Thousand[/tex]
Analyzing the statements one after the other:
The tens digit is 6 less than 8
[tex]B = 8 - 6[/tex]
[tex]B = 2[/tex]
The thousands digit is twice the digit in the tens place.
[tex]D = 2B[/tex]
[tex]D = 2 * 2[/tex]
[tex]D = 4[/tex]
The hundreds digit is the greatest odd number that is less than 10.
[tex]C = 9[/tex]
The ones digit is the product of 5 and 1.
[tex]A = 6 * 1[/tex]
[tex]A = 6[/tex]
The ten thousands digit is the difference between the hundreds digit and the ones digit.
[tex]E = C - A[/tex]
[tex]E = 9 - 6[/tex]
[tex]E = 3[/tex]
Ydia's address is: 62943

Sports companies cover the surface of a soccer ball with waterproof spray to prevent it from getting water logged. The radius of a soccer ball is 11cm. The formula to calculate Surface Area of a ball is SA = 4πr2 S A = 4 π r 2 . How much surface do they need to cover with the spray?
Answer:
310.73cm^2Step-by-step explanation:
The expression for the total surface area is
SA=4πr^2
given that r=11cm
we want to substitute the value of r to solve for the area
SA=4πr^2
SA=4*3.142*(11)^2
SA=2.568*11^2
SA=2.568*121
SA=310.728
Therefore they need to cover a surface of 310.73cm^2

What is the purpose of the AutoSum feature in Microsoft® Excel? A. To automatically add all numbers in all cells in a workbook B. To add a list of numbers in a spreadsheet C. To put a list of numbers in order before finding the sum D. To estimate the total of a list of numbers
Answer:
B. To add a list of numbers in a spreadsheet
Step-by-step explanation:
AutoSum feature in Microsoft Excel is used to automatically sum up a range of numbers within a horizontal row or vertical column without having to input a formula.
When a range of numbers are selected within a row or column, clicking on AutoSum will sum up the numbers in the adjacent empty cell. For example, if you wanted to add the values of cells between B1 and B10, highlight cells B1 through B10 and click the AutoSum button . The sum of B1 to B10 will be given in B11.
In Excel 2010 and later, the AutoSum feature is on the Home tab, in the Editing section.
