So I'm doing math and I could use some help.
Windows on the International Space Station are shown below. Suppose the long base of the window is 15.2 feet and the short base is 11.2 feet. The perpendicular height from one base to the other base is 8.4 feet. Draw one of the trapezoid-shaped windows on grid paper and label its dimensions. Describe the process you would use to find the area of one trapezoid-shaped window.
I already answered this question, but I just wanted to give you an idea on what i'm working with. This was my response:
Area of trapezoids = (base 1 + base 2) × (height ÷ 2)
(15.2 + 11.2) × (8.4 ÷ 2) = 110.88
The area is 110.88 feet²
Now this is the question I need help on:
Calculate the area of the window using the dimensions given in Part A. Show your work and explain your reasoning.

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?
Answer:
4 (rounded to the nearest whole number)
Step-by-step explanation:
total height = 3 x 2 = 6
Volume = radius^2 * pi * height
75.36= radius^2 * pi * 6
75.36/pi = radius^2 * 6
23,987833 = radius^2 * 6
23,987833/6 = radius^2
3,997972 = radius^2
radius = 1,999493
diameter = radius x 2 = 1,999493 x 2 = 3,998986

Answer:
[tex]\sqrt{18.04}[/tex]
Step-by-step explanation:
The wording is a bit confusing, but i beleive it basically means that we're trying to find the length on a leg of a triangle with a leg length of 3 and a hypotenuse of 5.2
if we write this out as an equation, it gives us:
[tex]5.2^{2}-3^{2}[/tex]
If we then simplify this, we get 27.04 - 9, which then simplifies to 18.04.
We then need to get the square root of this number to get the answer, thus the answer is [tex]\sqrt{18.04}[/tex]

Answer:
x > 10.5
Step-by-step explanation:
The point is on 10.5
The point is open which means that 10.5 is not included in the solution and we will be using < or >
The line is pointing towards numbers that are greater than 10.5 Which means that x is greater than 10.5
Hence, the answer is x > 10.5

One-fifth the product of 1 and −5
Five times the sum of −8 and 4
Answers:
-24
-20
-1
1
18
Answer:
down below.
Step-by-step explanation:
One–third of the product of −8 and 9 = -24
-8(9) = -72
-72 / 3 OR -72(1/3) = -24
Half the sum of 8 and −6 = 1
8 + (-6) =2
2 / 2 = 1
Three times the sum of 12 and −6 = 18
12 + (-6) = 6
6 * 3 = 18
One-fifth the product of 1 and −5 = -1
1(-5) = -5
-5/5 = -1
Five times the sum of −8 and 4 = -20
-8 + 4 = -4
-4 * 5 = -20
What is true about the figure?
In the figure, angles C and D are a:
.
Therefore, angle C must measure:
Answer:
acute angles... I think 35
Angle A: 56 degrees.
Angle B: 34 degrees.
Angle C: 56 degrees.
Angle D: 124 degrees.
Step-by-step explanation:
Angle A = 180-124, or 56 degrees.
The right angle given plus Angle B must equal 124, so 124-90 = 34 degrees.
Angle B = 34 degrees.
Angle C = 180-124, or 56.

Your teacher decides to determine groups in your class by pulling names out of a hat and not replacing them. What type of even is this?
Answer:
Social Loafing
Step-by-step explanation:
In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when working alone. It is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals.
The event is an example of a combination.
What is a combination?It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.
We have,
This event is an example of a non-replacement or non-independent event.
In probability theory, an event is said to be non-replacement or non-independent if the outcome of a previous event affects the outcome of the current event.
In this case,
Once a name is pulled out of the hat, it is not replaced, meaning that the probability of pulling out a certain name changes with each draw.
For example, if a name is pulled out of the hat, the probability of pulling out that same name again decreases because it is no longer in the hat.
Therefore,
This event is non-replacement or non-independent.

Betsy started a business 2 years ago. She had 8 customers in the first year. She added 18 customers in the second year. Betsy's goal is that in each of the next 4 years, she will have three times ad many customers as the year before. Betsy shows her calculations in the TABLE below that if she meets this goal each year, she will have 312 customers 4 years from now. is Betsy correct? Use the drop-down menus to explain your reasoning.
Expression: (8 + 18) * 3^4
Step 1: 26 * 3^4 <<< TABLE
Step 2: 26 * 12
Answer: 312
Pick the correct answer in parentheses:
Betsy's calculations in Step 1 are ( is she Correct or Incorrect) because... ( .She added incorrectly .She has 26 customers at the end of her second year .She should have multiplied 18 * 3^4 before adding 8)
Besty's calculations in Step 2 are ( is she Correct or Incorrect) Because.... ( .She did not find the correct value of 3^4 .26 * 3^4 = 26 * 12 .She did not apply the order of operations correctly)
If Betsy reaches her goal each year, she will have.. ( .2,106 .312 .1,466) customers 4 years from now.
Answer: step one is correct and the second step is incorrect
Step-by-step explanation:
Answer:
Betsy isn't correct. Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.
Step-by-step explanation:
26 × 3 × 4 is different from 26 × 3⁴
- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.
- Betsy started her business 2 years ago.
- In the first year, Betsy has 8 customers.
- In the second year, Betsy added 18 customers,
- So, her customers are now 8+18 = 26
- Betsy's goal is that in each of the next 4 years, she will have three times as many customers as the year before.
If the base number of customers is truly 26 this year,
Next year, Betsy would have 26 × 3 = 78 customers.
In 2 years, she would have 78 × 3 = 234
Thus indicating that in t years from now, the number of her customers will be
N(t) = N₀ × 3ᵗ
where
N(t) = number of customers t time from now
N₀ = number of customers at the moment = 26
t = number of years from now.
N(t) = 26 × 3ᵗ
In 4 years from now, Betsy will have
N(t=4) = 26 × 3⁴ = 2,106
So, it is evident that Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.
26 × 3 × 4 is different from 26 × 3⁴
- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.

Answer:
There are about 3 students that are left handed in a class. First Sara took the percentage of left handed people, 11%, and multiplied it by the amount of students in the class, 30. She got 3.3 but you can't have 0.3 of a person so she rounded it down to 3.
Answer:
Her first step is stating that left-handed people represent 11% of 30 people, which results in 3 people.
