The fastest elevators in the Burj Khalifa can travel 330 feet in just 10 seconds. How far does the
elevator travel in 11 seconds? Explain your reasoning.
Answer:
363 feet = 11 seconds
Step-by-step explanation:
330 feet = 10 seconds
=> 330/10 feet = 10/10 seconds
=> 33 feet = 1 second
=> 33 × 11 feet = 11 × 1 second
=> 363 feet = 11 seconds.
Therefore, the Burj Khalifa can travel 363 feet in 11 seconds.
Answer:
[tex]363ft[/tex]
Step-by-step explanation:
First we know that the elevator can travel 330 feet in just 10 seconds. That's can be interpret as:
[tex]\frac{330ft}{10s} = \frac{33ft}{1s}[/tex]
How you can see each second the elevator travel 33 feet so if you want to know how many travel in 11 second you only have to multiply by 11 the 33ft.
[tex]33ft \cdot 11s = 363ft[/tex]

if there are jelly beans in a jar: 4 green, 2 white, and 5 purple. what is the probability of choosing a white jelly bean and then a purple if you put the white jelly bean back in the jar?
Answer:
Probability of choosing a white jelly bean: 18.18181818%
Probability of choosing a purple jelly bean: 45.45454545%
Step-by-step explanation:
Part #1:
4 (green) + 2 (white) + 5 (purple) = 11 jelly beans
2 white / 11 total
probability percentage (of choosing a white jelly bean) over 100% (100% = all 11 jelly beans) is equal to 2 (white jelly beans) over 11 (11 = 100% of the jelly beans)
[in other words, 11 jelly beans is 100%]
#1: unknown/100% = 2/11
#2: divide 2 by 11 (2/11 = 0.1818181818)
#3: multiply both sides by 100 (0.1818181818 * 100 = 18.18181818%)
Probability of choosing a white jelly bean: 18.18181818%
Part #2:
4 (green) + 2 (white) + 5 (purple) = 11 jelly beans
5 purple / 11 total
probability percentage (of choosing a purple jelly bean) over 100% (100% = all 11 jelly beans) is equal to 5 (purple jelly beans) over 11 (11 = 100% of the jelly beans)
[in other words, 11 jelly beans is 100%]
#1: unknown/100% = 5/11
#2: divide 5 by 11 (5/11 = 0.4545454545)
#3: mulitply both sides by 100 (0.4545454545 * 100 = 45.45454545%)
Probability of choosing a purple jelly bean: 45.45454545%

The sum of three numbers is 301. The second number is 3 less than twelve times the first number. The third number is 4 more than seven times the first number. Find the three numbers.
Answer:
Smallest number = 15
Second number = 177
Third number = 109
Step-by-step explanation:
Givens
Let the first number = x
Let the second number = 12x - 3
Let the third number = 7x + 4
Equation
x + 12x - 3 + 7x +4 = 301 Combine like terms
Solution
20x + 1 = 301 Subtract 1 from both sides
20x = 301 - 1 Combine
20x = 300 Divide by 20
x = 300/20
x = 15

y^2 − 20x − 6y − 51 = 0
answer:
Simplifying Y2 + -20X + -6y + -51 = 0
Reorder the terms: -51 + -20X + Y2 + -6y = 0
Solving -51 + -20X + Y2 + -6y = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '51' to each side of the equation. -51 + -20X + Y2 + 51 + -6y = 0 + 51
Reorder the terms: -51 + 51 + -20X + Y2 + -6y = 0 + 51 Combine like terms: -51 + 51 = 0 0 + -20X + Y2 + -6y = 0 + 51 -20X + Y2 + -6y = 0 + 51
Combine like terms: 0 + 51 = 51 -20X + Y2 + -6y = 51
Add '-1Y2' to each side of the equation. -20X + Y2 + -1Y2 + -6y = 51 + -1Y2
Combine like terms: Y2 + -1Y2 = 0 -20X + 0 + -6y = 51 + -1Y2 -20X + -6y = 51 + -1Y2 Add '6y' to each side of the equation. -20X + -6y + 6y = 51 + -1Y2 + 6y Combine like terms: -6y + 6y = 0 -20X + 0 = 51 + -1Y2 + 6y -20X = 51 + -1Y2 + 6y Divide each side by '-20'. X = -2.55 + 0.05Y2 + -0.3y Simplifying X = -2.55 + 0.05Y2 + -0.3y

Step-by-step explanation:

Points C open parentheses negative 5 comma 8 close parentheses and D open parentheses 2 comma 5 close parentheses lie on line C D. If points C apostrophe and D apostrophe are created by translating points C and D left 6 units, what is the slope of line C apostrophe D apostrophe ?
We want to find the slope of the line that connects points C' and D'. We will find that the slope is -3/7.
First, we start with the points:
C = (-5, 8)D = (2, 5)Now we create points C' and D' by translating points C and D to the left by 6 units, this means that we need to subtract 6 in the x-value of each point, so we will have:
C' = (-5, 8) + (-6, 0) = (-5 - 6, 8) = (-11, 8)D' = (2, 5) + (-6, 0) = (2 - 6, 5) = (-4, 5)And we know that if a line passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Then the slope that connects points C' and D' is:
[tex]a = \frac{5 - 8}{2 - (-5)} = \frac{-3}{7}[/tex]
