The elevator that takes passengers from the lobby of the John Hancock Centre in
Chicago to the observation level travels 300 feet in 5 seconds. The observation level
is located on the 100th floor, at 1200 feet above the ground. Find the time it takes
the elevator to travel from the lobby to the observation level. (4)
Answer:
20 seconds
Step-by-step explanation:
s = Distance traveled by elevator = 300 ft
t = Time taken = 5 seconds
Velocity is given by
[tex]v=\dfrac{s}{t}\\\Rightarrow v=\dfrac{300}{5}\\\Rightarrow v=60\ \text{ft/s}[/tex]
Distance to the observation level from the lobby = 1200 ft
Time taken is given by
[tex]t=\dfrac{1200}{60}\\\Rightarrow t=20\ \text{s}[/tex]
Time taken to reach the observation level from the lobby is 20 s.

The independent variable represents the cost of the meal for 70 people.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given when the manager quotes a price for a banquet, she is including the cost of renting the room plus the cost of the meal for each person. A banquet for 70 people costs $1300. For 120 people, the cost is $2200.
The expression will be written as,
Total cost = 70x + cost of rent
Therefore, the independent variable represents the cost of the meal for 70 people.

Which equation should you use to solve for x?
40°
60°
16x
O 60 + 16x + 40 = 180
O 60 + 40 = 16x
0 60 + 16x = 40
O 60 + 16x + 40 = 90
Answer:
1st Option
Step-by-step explanation:
All angles in a triangle must add up to 180°.
Step 1: Set up equation
40° + 60° + 16x = 180°
Step 2: Rewrite
60° + 16x + 40° = 180°
Answer:
Option: A.
Step-by-step explanation:
Hey there!
In the given triangle;
60° +16x° + 40° = 180° { Sum of interior angle of a triangle}
100° + 16x= 180°
16x = 180° - 100°
[tex]x = \frac{80}{16} [/tex]
Therefore, X= 5°.
So, Option A (equation) is used for solving the value of"X".

Answer:
n = -1 n = -7
Step-by-step explanation:
5| 2n+8| +3 = 33
Subtract 3 from each side
5| 2n+8| +3-3 = 33-3
5| 2n+8| = 30
Divide by 5
5/5| 2n+8| = 30/5
| 2n+8| = 6
An absolute value equation has two solutions, one positive and one negative
2n+8 = 6 2n+8 = -6
Subtract 8 from each side
2n+8-8=6-8 2n+8-8 = -6-8
2n = -2 2n = -14
Divide by 2
2n/2 = -2/2 2n/2 = -14/2
n = -1 n = -7

Determine the height of the triangle if the area is 24 square inches and the base is 12 inches.
Answer:
4
Step-by-step explanation:
We use 1/2base times height to find the area and since we already have an area we just do 24= 6h then we divide 6 on both sides and height equals 4
Answer: 6 inches
Step 1: Subtract 12 because 12 iches is the base.
24 - 12 = 2
Step 2: Divide 12 by 2 because triangles have two equal sides.
12 ÷ 2 = 6
Answer = 6
(13/7)^2 as a simplified proper fraction or a simplified improper fraction?
Answer:
Simplified improper fraction.
Step-by-step explanation:
A simplified proper fraction would not have a numerator bigger than the denominator.
An improper fraction would have a numerator bigger than the denominator that can be simplified.
We see here that the expression isn't proper as it can be simplified further. Therefore, it is improper.
Answer: Simplified improper fraction.

During a promotional weekend, a state fair gives a free admission to every 188th person that enters the fair. On Saturday, there were 6,737 people attending the fair. On Sunday, there were 8,669 people attending the fair. How many people received a free admission over the two days?
Answer: 81 people
Step-by-step explanation:
Number of people that attended fair on Saturday = 6737
Number of people that got free admission = 6737/188 = 35.8.
Free admission on Saturday = 35
Number of people that attended fair on Saturday = 8669
Number of people that got free admission = 8669/188 = 46.1
Free admission on Sunday = 46
The people who received a free admission over the two days will be:
= 35 + 46
= 81 people

Write the equation in vertex form using the following information: vertex (4, -6) and a=1.
Submit
Answer:
y = (x - 4)² - 6Step-by-step explanation:
An equation of a quadratic function in a vertex form is y=a(x-h)²+k, where vertex is (h, k)
vertex (4, -6) means h = 4 and k = - 6
So:
y = 1(x - 4)² + (-6)
y = (x - 4)² - 6
