Two people meet in the conference room on the fourth floor of a building. On departure, one person travels West
24 feet, South 18 feet, and Down 18 feet. The other person travels North 24 feet, East 12 feet, and Up 18 feet.
How far apart are the two people? Round to the nearest tenth.
Answer:
36*(5)^0.5
Step-by-step explanation:
distance on horizontal 36 feet
distance on vertical 78 feet
so distance between them = (36^2+78^2)^0.5 = 36*(5)^0.5
The two people are 66 feet apart from each other.
How to elaborate the problem ?
The 1st person travels 24 feet west, 18 feet south and 18 feet down.
The location of 1st person is (-24, -18, -18) , the negative sign is to convert all in same direction.
The 2nd person travels 12 feet east, 24 feet north and 12 feet up.
The location of 2nd person is (12, 24, 18)
How to find the distance between them ?The distance between (-24, -18, -18) & (12, 24, 18 = [tex]\sqrt{(-24-12)^{2}+(-18-24)^{2}+(-18-18)^{2} }[/tex] feet
= [tex]\sqrt{(-36)^{2}+(-42)^{2}+(-36)^{2} }[/tex]) feet
= 66 feet

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 the outer
edge of any one piece of this circle?
Answer:
Step-by-step explanation:
diameter/2 = radius
12/2 = radius
radius = 6
The outer edge means you are measuring the circumference of the pizza.
Circumference = 2(pi)(radius)
Circumference = 2(pi)(6)
You are only finding 1/8 of the circumference
Therefore you are multiplying the circumference by 1/8
Length of 1 slice = (1/8)((2)(pi)(6)) = (12/8)(pi) = (3/2)(pi) = (3(pi)) / (2) or 4.71 inches
The length of the outer edge of any one piece of this circle will be 4.71 inches.
What is the arc length of the sector?Let r is the radius of the sector and θ be the angle subtends by the sector at the center. Then the arc length of the sector of the circle will be
Arc = (θ/360°) 2πr
A circle is drawn to represent a pizza with a 12-inch diameter. The circle is cut into eight congruent pieces. Then the central angle of each sector will be given as,
θ = 360° / 8
θ = 45°
And the radius is given as,
r = 12/2
r = 6 inches
Then the length of the outer edge of any one piece of this circle will be
Arc = (θ/360°) 2πr
Arc = (45/360°) 2π x 6
Arc = 1/4 x 3.14 x 6
Arc = 4.71 inches
The length of the outer edge of any one piece of this circle will be 4.71 inches.

multiply 2 5/8 times - 2 3/5 what is the answer
Step 1: Change the Mixed Numbers into Improper Fractions
---To do so, multiply the number by the denominator and add that product to the numerator.
2 x 8 = 16 + 5 = 21
21 / 8
2 x 5 = 10 + 3 = 13
13 / 5
Step 2: Multiply the Improper Fractions
---When multiplying fractions, multiply straight across (numerator x numerator and denominator x denominator).
21 / 8 x 13 / 5 = (21 x 13) / (8 x 5) = 273 / 40
Step 3: Simplify
---Change the improper fraction back into a mixed number a simplify if necessary.
40 x 6 = 240
273 - 240 = 33
6 33/40

Answer:
238
Step-by-step explanation:
Given equation: [tex]a^2+1=6a[/tex]
Rearrange so that it is equal to zero:
[tex]\implies a^2-6a+1=0[/tex]
Quadratic formula
[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0[/tex]
Using the quadratic formula to solve the given equation:
[tex]\implies a=\dfrac{-(-6) \pm \sqrt{(-6)^2-4(1)(1)} }{2(1)}[/tex]
[tex]\implies a=\dfrac{6 \pm \sqrt{32}}{2}[/tex]
[tex]\implies a=3 \pm 2\sqrt{2}[/tex]
[tex]\implies a^2=17 \pm 12\sqrt{2}[/tex]
Substituting this into [tex]7\left(a^2+\dfrac{1}{a^2}\right)[/tex]
[tex]\implies 7\left(17 \pm 12\sqrt{2}+\dfrac{1}{17 \pm 12\sqrt{2}}\right)[/tex]
For [tex]17+12\sqrt{2}[/tex]:
[tex]\implies 7\left(17+12\sqrt{2}+\dfrac{1}{17+12\sqrt{2}}\right)[/tex]
[tex]\implies 7\left(\dfrac{(17+12\sqrt{2})^2}{17+12\sqrt{2}}+\dfrac{1}{17+12\sqrt{2}}\right)[/tex]
[tex]\implies 7\left(\dfrac{(17+12\sqrt{2})^2+1}{17+12\sqrt{2}}\right)[/tex]
[tex]\implies 7\left(\dfrac{289+408\sqrt{2}+288+1}{17+12\sqrt{2}}\right)[/tex]
[tex]\implies 7\left(\dfrac{578+408\sqrt{2}}{17+12\sqrt{2}}\right)[/tex]
[tex]\implies 7\left(\dfrac{34(17+12\sqrt{2})}{17+12\sqrt{2}}\right)[/tex]

For [tex]17-12\sqrt{2}[/tex]:
[tex]\implies 7\left(17-12\sqrt{2}+\dfrac{1}{17-12\sqrt{2}}\right)[/tex]

Al and his sister share a pizza cut into six equal pieces.
Ali eats of all the pieces. His sister eats of the remaining pieces.
After both Ali and his sister have eaten, what fraction of the pizza is left?
When both Ali and his sister have eaten, the fraction of the pizza that is left will be 5/12.
How to calculate the fraction?From the complete information, Ali eats 1/3 and his sister eats 1/4 of the pizza. Therefore, the number eaten by Ali will be:
= 1/3 × 6 = 2
The number eaten by the sister will be:
= 1/4 × 6 = 1.5
The remaining fraction will be:
=1 - (2 + 1.5)/6
= 1 - (3.5/6)
= 2.5/6
