4 + 8|2b| = 84
8|2b| = 80
|2b| = 10
Now to solve the absolute value part, set what is inside the absolute value equal to 10 and set it equal to -10 and solve both equations.
2b = 10 or 2b = -10
b = 5 or b = -5

find the coordinates of the orthocenter for a triangle with vertices (1,3) , (1,12) , (8,10)
Answers
The orthocenter is where the three altitudes of the triangle meet. That is, where the perpendicular lines from each vertex to the opposite side meet.
the goal in this case is to find out where the perpendicular line from C to AB, the perpendicular line from B to AC, and the perpendicular line form A to BC meet.
It is enough to find two perpendicular lines.
step one: find the equation of two perpendicular lines
find the slope of AB: m=(12-3)/(1-1), notice the denominator is 0, so the slope doesn't exist, that means AB is a vertical line parallel to the y axis, so the perpendicular line has a slope of o, a horizontal line. this horizontal line goes through C(8,10), so the equation is y=10
use the same method, slope of AC: (10-3)/(8-1)=1, so the perpendicular line from B to AC has a slope of -1. y=-x+b
Now use the point B(1,12) to find b: 12=-1+b =>b=13
so the equation for this line is y=-x+13
Step two: solve the system of equations: y=10
y=-x+13
we get x=3, y=10, which are the coordinates of the orthocenter.
I've also found the equation of the third line, which is y=(7/2)x-1/2, the point (3,10) is also on this line. So it works!
Fashion Phreddy buys 5 shirts and 3 ties for 91 on the bargain bus. Billy joe bob buys 8 shirts and 5 ties for 146. If all the shirts sold for the same price and each ties were priced identically. How much was each shirt and tie.
Answers
Fashion Phreddy buys 5 shirts and 3 ties for 91. This means that:
5x + 3y = 91 .........> equation I
5x = 91-3y
x = 18.2 - (3/5) y ..........> equation II
Billy joe bob buys 8 shirts and 5 ties for 146. This means that:
8x + 5y = 146 ...........> equation III
Substitute with equation II in equation III:
8(18.2 - (3/5) y) + 5y = 146
145.6 - 4.8y + 5y = 146
0.2y = 0.4
y = 2
Substitute in equation II to get the value of x:
x = 18.2 - (3/5) (2) = 17
Based on the above calculations:
price of T-shirt = x = 17
price of tie = y = 2

A ladder is leaning against the side of a building. The building and the ground form a right angle. How high on the building will the ladder touch if the ladder is 10 ft long and the base of the ladder is 6 ft from the base of the building?
Answers
8 ft
6, 8, 10 are lengths of a Pythagorean triple
6^2 + 8^2 = 10^2
The height of wall where the ladder touches it is 8 ft.
Given that, a ladder is leaned against a wall, the building and the ground form a right angle, we need to find that how high on the building will the ladder touch,
So, here using the Pythagoras theorem,
Formula =
a²+b² = c², a, b and c are the sides of a right triangle,
Here, c = 10 ft, b = 6 ft we need to find the a,
a²+6² = 10²
a² = 100-36
a² = 64
a = 8
Hence, the height of the wall where the ladder touches it is 8 ft.

A turtle fell to the bottom of a deep well. The turtle climbed up 2 meters on the first day, but slipped back 1 meter as he rested. The second day, the turtle climbed double the distance of the previous day, but slipped and lost ½ of the day’s climbed distance as he rested. This pattern continued until the end of the fourth day, when the turtle realized he was halfway to the top of the well. How deep was the well?
Answers
Analyzing the climbing pattern of the turtle for four days shows that it climbed 15 meters which is halfway to the top, thus the entire depth of the well is 30 meters.
The question asks for the determination of the depth of a well based on a pattern observed in a turtle's attempt to climb out of it. To do this, we need to analyze the climbing and slipping pattern for four days until the turtle is halfway out of the well.
On the first day, the turtle climbed up 2 meters and slipped back 1 meter, netting a 1 meter gain. On the second day, the distance climbed is double that of the previous day (2 meters x 2 = 4 meters), but the turtle loses half of it while resting, which means a gain of 2 meters for the second day (4 meters / 2 = 2 meters). Following the pattern:
Day 1: +2 - 1 = +1 meterDay 2: +(2 x 2) - (4 / 2) = +2 metersDay 3: +(4 x 2) - (8 / 2) = +4 metersDay 4: +(8 x 2) - (16 / 2) = +8 metersThe total distance climbed after four days is 1 + 2 + 4 + 8 = 15 meters. Since this is halfway to the top, the entire depth of the well would be 15 meters imes 2 = 30 meters.
how do i evaluate 256 1/4 .? this is algebra 2.
Answers
The value of the 256 1/4 is 384.25
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and a remainder is a mixed fraction. we can convert the mixed fraction to an improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and the remainder as the numerator of the proper fraction keeping the denominator.
We have the fraction as 256 1/4
First, we will multiply 256 with 4.
256 x 4 = 1536
1536 + 1
= 1537
Then
1537 / 4 = 384.25

I need to find the LCD or LCM for this equation I Also need with n is please help ... 3/4n-18=1/4n-14
Answers
We need to isolate "n"
So, add 18 to both sides.
3/4n = 1/4n - 14 - 18
Then, subtract 1/4n from both sides.
3/4n - 1/4n = -14 - 18
*Note : Since "n" has the same denominator (bottom number in a fraction), then we simply need to look at the top numbers (numerators) and simplify those.
Simplify.
2/4n = -32
Then, multiply both sides by 4 so that we get rid of fractions.
4 · 2/4n = -32 · 4
Simplify.
2n = -128
Now, divide both sides by 2.
2 ÷ 2n = -128 ÷ 2
Simplify.
n = -64

a plane takes off at 6 am, traveling north at 270 mph. a jet takes iff at 7 am, traveling north at 460 mph. at what time will the jet overtake the plane?
Answers
[tex]d=rt[/tex]
Now, if the jet overtakes the plane, then at some point their distances will be the same. This means their rate * time will be equal.
Let's call the rate for the first plane, r1, and the rate for the second plane, r2. If we set time as t, then we can create ourselves a formula. However, we have to add one to the time of the first plane since it leaves one hour earlier. In the end, we should have something like this:
[tex]r_{1}(t+1)= r_{2}t [/tex]
If you plug in the values, you should get:
[tex]t = 0.704h[/tex]

find A common denominator of 1/6 and 1/9. rewrite the pair of fractions using common denominator.
Answers
Answer:
the pair would be 3/18 and 2/18
The pair of fractions, 1/6 and 1/9, can be rewritten as 3/18 and 2/18, respectively, using the common denominator of 18.
We have,
The prime factorization of 6 is 2 * 3.
The prime factorization of 9 is 3 * 3.
To find the LCM, take the highest power of each prime factor:
LCM = 2 * 3 * 3 = 18
The common denominator for 1/6 and 1/9 is 18.
To rewrite the fractions using the common denominator of 18:
1/6 = (1/6) * (3/3) = 3/18
1/9 = (1/9) * (2/2) = 2/18
Thus,
The pair of fractions, 1/6 and 1/9, can be rewritten as 3/18 and 2/18, respectively, using the common denominator of 18.
