The balcony can hold 25 people of 160-pound weight.
According to the question,
We have the following information:
The maximum weight balcony can hold = 1816 kg
Weight of 1 person = 160 pound
Now, we will convert this weight into kilogram so that both the measurements have same units.
1 pound = 0.454 kg
160 pound = 160*0.454 kg
160 pound = 72.64 kg
Now, let's take the number of people balcony can hold to be x.
So, we have:
72.64x = 1816
x = 1816/72.64
x = 25
Hence, the number of people the given balcony can hold is 25.

A car's velocity is modeled by v(t) = 0.5t^2 -14t+ 80 for 0 less than or equal to t less than or equal 14, where the velocity is in feet per second and time is in seconds. Where does the car come to a complete stop?
The car stops after moving for 20 seconds
How to determine when the car comes to a stop?From the question, the function is given as
v(t) = 0.5t^2 - 14t + 80
When the car comes to a stop, the vehicle is 0
This is represented as
v(t) = 0
So, we have
0.5t^2 - 14t + 80 = 0
Expand the equation
0.5t^2 - 10t - 4t + 80 = 0
Factorize the equation
0.5t(t - 20) - 4(t - 20) = 0
So, we have
(0.5t - 4)(t - 20) = 0
Solve for t
t = 8 and t = 20
20 is greater than 8
Hence, the car comes to a stop at 20 seconds

Applying the trapezoid midsegment theorem, the diameter of the bottom layer of the cake = KS = 26 inches.
What is the Diameter of a Circular Shape?The diameter of any circular shape is the length of the line segment that divides the shape into two equal halves and runs through its center.
What is the Trapezoid Midsegment Theorem?The trapezoid midsegment theorem states that the length of the midsegment of a trapezoid that is parallel to its bases is equal to half of the sum of the bases.
Using the trapezoid midsegment theorem we have:
MQ = 1/2(NP + LR)
Substitute
MQ = 1/2(8 + 20)
MQ = 1/2(28)
MQ = 14 inches
Also, we would also have:
LR = 1/2(MQ + KS) [trapezoid midsegment theorem]
Substitute
20 = 1/2(14 + KS)
40 = 14 + KS
40 - 14 = KS
26 = KS
KS = 26

Use 1-Prop Z Int to create a 95% confidence interval.
Z test should be employed because there is only one set of samples collected and the sample size is huge.
An observed percentage is compared to a theoretical one using a one proportion z-test. The test statistic is determined as follows:
z = (p-p0) / √(p0(1-p0)/n)
where:
p = observed sample proportion
p0 = hypothesized population proportion
n = sample size

A group of tourists needs rental cars to get around the city. There are 3,376 tourists in
the group. If each rental car holds 8 people, how many cars will the group need?
Using division, we know that the number of cars needed by 3,376 tourists is 422.
What is division?The division is splitting into equal parts or groups.The division allows us to divide or 'share' numbers to find an answer.Division sign (÷) is a symbol consisting of a short horizontal line with a dot above and another dot below, used to indicate mathematical division.The division of any number by zero is undefined. In this case, the result can be written as infinity. For example, 15/0 = ∞, i.e. undefined.We can represent the division with ÷, slash (/), or a horizontal line ( _ ). We can use these symbols at our convenience when dealing with different types of computations or division questions.So, the total number of groups of tourists = 3376
One car holds 8 people.To find the number of cars needed. Hence,
The number of cars needed = 3376/8= 422Therefore, using division we know that the number of cars needed by 3,376 tourists is 422.

What are the Missing Angles? Are these triangles the similar or Not similar?
Answer:
The missing angle in Triangle A is 66 degrees
The missing angle in Triangle B is 34 degrees
Because Triangle A has measures of 34 degrees, 80 degrees, and 66 degrees
and
Triangle B has measures of 80 degrees, 66 degrees, and 34 degrees, we can conclude that THEY ARE SIMILAR TRIANGLES
Explanation:
The sum of angles in a triangle is 180 degrees.
Given that triangle A has m<1 = 34 degrees, m<2 = 80 degrees. Let the missing angle be x, then
x + 34 + 80 = 180
x + 114 = 180
Subtract 114 from both sides
x = 180 - 114
= 66 degrees
Triangle B has m<1 = 80 degrees, m<2 = 66 degreess. Let the missing angle be y, then
y + 80 + 66 = 180
y + 146 = `180
Subtract 146 from both sides
y = 180 - 146
= 34 degrees
Triangles A and B are similar, since they have similar measure of angles.
What is the answer for this as the y- intercept of two points? (-6,-5) and (-4,-4)

What are angles?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by joining two rays at their termini. In most cases, an angle is expressed in degrees. In geometry, there are several different kinds of angles.So, the value of 2x and x:
