Kayla gets on the elevator on the ground floor. She goes down 2 floors, up 5 floors, down 1 floor, up 3 floors, down 5 floors, and up 6 floors. What floor is she on?
Answer:
I belive its the 6th floor, although i did the mathb in my head. I apologize if it is incorrect ;-;
Step-by-step explanation:
Answer:
6th floor
Step-by-step explanation:
Starting on the ground floor, we will reference this point as the 0th floor. From there she goes:
down 2 floors (0 - 2) | -2 |
up 5 floors (-2 + 5) | 3 |
down 1 floor (3 - 1) | 2 |
up 3 floors (2 + 3) | 5 |
down 5 floors (5 - 5) | 0 |
and up 6 floors (0 + 6) | 6 |
Therefore... in the end she lands on the 6th floor

what's the slope of (-3,8) and (3,8)
Answer:
The slope is 0
Answer:
0
Step-by-step explanation:
In this, the x value is the only one changing, not the y ones. So, if the x values change, and the y values don't, you get a horizontal line. A horizontal line has a slope of zero.

The difference between five and a number squared
Answer:
5 and a number squared
n could be represented as a number
difference is subtraction
5-n squared
The difference between 5 and a number squared is 5 - x².
What are squares and cubes ?When a number is multiplied by it self once we call it a square and when a number is multiplied by it self twice we call it cube of that number.
for example 5 is multiplied by it self once = 5x5 = 5²
5 is multiplied by it self twice = 5x(5x5) = 5x5² = 5³
Let the given number is x , So the difference between 5 and a number squared is = 5 - x²

Cost of admission to a town fair was $8 for adults and $5 for children. If 206 people
attended the fair, and ticket sales totaled $1408, how many adult tickets were sold?
Help
Answer:
126 adult ticketsStep-by-step explanation:
Step one:
let the number of adults be x
and the number of children be y
cost of tickets $8 for adults and $5 for children
total tickets is 206
total money made=$1408
Step two:
The system of equation is
x+y=206--------1
8x+5y=1408-----2
from 1 x=206-y
put x=206-y in equation 2 we have
8(206-y)+5y=1408
1648-8y+5y=1408
-3y=1408-1648
-3y=-240
divide both sides by -3
y=80 children tickets
put y=80 in x+y=206--------1
x+80=206
x=206-80
x=126 adult tickest
126 adult tickest
8. Separate 84 into two parts such that one part will be 12 less than twice
the other.
Answer:
x + (2x-12) = 84
x = 32
Step-by-step explanation:
you can say (part 1) + (part 2) = 84
one part is x (a variable) and
other part is 12 less than twice the other: when it says "12 less" is " - 12" and twice of part one 2x, you can say (2x - 12)
(part 1) + (part 2) = 84
x + (2x-12) = 84
3x - 12 = 84
3x = 96
x = 32
(part 1) + (part 2) = 84
(32) + (2*32 - 12) = 84
(32) + (52) = 84

What is the approximate length of the missing side of a right triangle with hyptonenuse of 16
cm and other side of 15 cm?
Answer:
5.56cmStep-by-step explanation:
Step one:
given data
hyp=16cm
say the adjecent= 15
let the hypotenuse be z
and the adjacent be x, while the missing side, the opposite be y
by Pythagoras theorem
[tex]z^2=y^2+x^2[/tex]
[tex]z=\sqrt{x^2+y^2}[/tex]
substitute the values we have
[tex]16^2=y^2+15^2\\\\256=y^2+225\\\\256-225=y^2\\31=y^2\\\\y=\sqrt{31}[/tex]
[tex]y=5.56cm[/tex]

Round your answer to two decimal places.
Answer:
4 dollars
Step-by-step explanation:
The standard deviation of the pack of gaming cards is 4
The entry on the table is given as:
x | $10 | $20
P(x) | 20% | 80%
Also, we have:
[tex]\mu_x = 18[/tex]
The standard deviation of a dataset is calculated using:
[tex]\sigma_x = \sqrt{E(x^2) - \mu_x^2}[/tex]
Where:
[tex]E(x^2) = \sum x^2 \times P(x)[/tex]
This gives
[tex]E(x^2) = 10^2 \times 20\% + 20^2 \times 80\%[/tex]
[tex]E(x^2) = 340[/tex]
[tex]\sigma_x = \sqrt{E(x^2) - \mu_x^2}[/tex] becomes
[tex]\sigma_x = \sqrt{340 - 18^2}[/tex]
[tex]\sigma_x = \sqrt{340 - 324}[/tex]
[tex]\sigma_x = \sqrt{16}[/tex]
Take positive square root
[tex]\sigma_x = 4[/tex]
Hence, the standard deviation of the dataset is 4

equation of the line that passes through (1,2) and is perpendicular to the line Y equals 1/3 x + 4
Answer:
[tex]y = -3x + 5[/tex]
Step-by-step explanation:
The slope of a perpendicular line to the original equation is the opposite reciprocal of the slope of the original equation. This makes the opposite reciprocal -3, so the slope of the perpendicular line is -3. Now that we have found the slope, we will put it into the formula for slope, y = mx + b. This results in getting y = -3x + b.We know the values for x and y, (1,2) respectively. Plug these values into y = -3x + b. 2 = -3(1) + bb = 5This means that 5 is your y intercept and goes into place for b Therefore, your resulting equation is y = -3x + 5Task 5: A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. If it continues to fall at this rate, find each indicated temperature. What will the temperature be in 2 hours? Explain or show your reasoning.
Answer:
Step-by-step explanation:
To find answer,
We multiply 2 hours by the decrease, which is 3 degrees.
2*3=6 degrees
Now this means it will decrease 6 degrees in 2 hours, and starting from the start we do
0-6= -6 degrees in 2 hours
For five hours, we do
5*3=15
Now do the same
