The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area of a trapezoidal base of the prism with a height of 6 units?
Answer:
area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively
Step-by-step explanation:
Let us first be aware of formula of volume for any regular geometrical figure.
Fundamental formula for volume for any regular geometrical figure is.
volume = area of cross section of object* height of object (A)
In the problem stated area of cross section of object will be area of a trapezoidal base.
Given in the question is
Volume of both the trapezoidal prisms = 24 cubic units
*************************************************************************************
For prism with height 6 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 6 * area of a trapezoidal base
=> area of a trapezoidal base = 24/6 = 4 square units
*************************************************************************************
For prism with height 8 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 8 * area of a trapezoidal base
=> area of a trapezoidal base = 24/8 = 3 square units
*************************************************************************************
Therefore area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively.

D) 3/4
9514 1404 393
Answer:
A) 3 1/4
Step-by-step explanation:
Your calculator can help with this.
__
3/4 + ((1/3)/(1/6)) -(-1/2)
= 3/4 + ((2/6)/(1/6)) + 2/4
= 5/4 + 2/1
= 3 1/4
Q) 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2) = ?
→ 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2)
→ 3/4 + {(1/3) × (6/1)} - ( - 1/2)
→ 3/4 + 6/3 - ( - 1/2)
→ {(3/4) + (6/3)} + 1/2
→ 11/4 + 1/2
→ (11 + 2)/4 = 13/4
→ 3 1/4
Hence, option (A) is the answer.

Amanda ran three times last week. Here are the distances she ran (in kilometers).
9.14, 16.78, 17
What is the total distance amanda ran on these three days
You can add the four distances to get the total distance.
9+72+9+11.8= 101.8 total kilometers
***If you are looking for an average run per day, you would then take the total of 101.8 and divide it by 3 days (which would be 33.9 average kilometers run in 3 days).
im not sure if u mean "11.8"
Tanya wants to test the theory that the exterior angles of a
triangle add up to 360°. She draws triangle ABC and finds all
the angles in the triangle.
PLEASE HELP!!
Answer:
[tex]f + e + d = 360^o[/tex]
Step-by-step explanation:
The question is incomplete, as what is required is not stated and the triangle is not given.
So, I will solve generally.
The proof is as follows (see attachment for triangle)
From the attachment, we have:
[tex]a + f = 180[/tex]
[tex]b + e = 180[/tex]
[tex]c + d = 180[/tex]
Make f, e and d the subject
[tex]f = 180 - a[/tex]
[tex]e = 180 - b[/tex]
[tex]d = 180 - c[/tex]
Add up the equations
[tex]f + e + d = 180 -a + 180 - b + 180- c[/tex]
Collect like terms
[tex]f + e + d = 180 + 180+ 180-a- b - c[/tex]
[tex]f + e + d = 540-a- b - c[/tex]
We have:
[tex]f + e + d = 540-(a+ b + c)[/tex]
[tex]a + b + c \to 180[/tex] --- angles in a triangle
So, we have:
[tex]f + e + d = 540-180[/tex]
[tex]f + e + d = 360^o[/tex] --- proved

Because 3/8 is 0.375, 8/15 is 0.53( with the 3 repeated). The decimal values aren't the same so the answer is that these 2 fractions are not equivalent.
Please help me with this. NO LINKS.
Answer:
42.5 units²
Step-by-step explanation:
Total height of rectangle = 3.5 + 2 = 5.5 units
Total area (without triangles removed) = 5.5 x 9.0 = 49.5 units²
The measurements and area of the triangles removed are equal to those on the diagram, so calculate the area of the triangles and subtract them from the total area.
Left: (0.5)(2)(2) = 2 units²
Right: (0.5)(5)(2) = 5 units²
Area: 49.5 - 2 - 5 = 42.5 units²

The table shows the probability distribution of siblings of students in a high school with 1500 students. What is the expected value for the number of siblings of a randomly chosen student?
A. 2.5
B. 1.29
C. 1.08
D. 1.11
The expected value for the number of siblings of a randomly chosen student is 1.11.
What is expected value mean?"In a probability distribution, the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value".
For the given situation,
The table shows the probability distribution of siblings of students in a high school with 1500 students.
For number of siblings = 0, Probability = 0.18.
For number of siblings = 1, Probability = 0.65.
For number of siblings = 2, Probability = 0.09.
For number of siblings = 3, Probability = 0.05.
For number of siblings = 4, Probability = 0.02.
For number of siblings = 5, Probability = 0.01.
The formula for expected value mean, E(x) = ΣxP(x)
[tex]E(x)=(0)(0.18)+(1)(0.65)+(2)(0.09)+(3)(0.05)+(4)(0.02)+(5)(0.01)[/tex]
⇒ [tex]E(x)=1.11[/tex]
Hence we can conclude that the expected value for the number of siblings of a randomly chosen student is 1.11.

Samantha is selling raffle tickets for $1.50 each. At the end of the night she knows that she has made at most $84 in sales. If n represents the number of tickets Samantha sold, then which inequality below models the information given?
Answers
1.50n>84
1.50n<84
1.50n≥84
1.50n≤84
Answer:
1.50n≤84
Step-by-step explanation:
The statement indicates that Samantha knows that she has made at most $84 in sales and this means that that is the higher amount she thinks she can have. So, the total amount could be less than that or equal to that. Also, the total amount she has would be the result of multiplying the price per ticket for the number of tickets sold. Moreover, this amount would be less than or equal to 84 and the symbol that represents less than or equal to is ≤. According to this, the inequality that would model the information is: 1.50n≤84.

A person invested $440 in an account growing at a rate allowing the money to double every 8 years. How long, to the nearest tenth of a year would it take for the value of the account to reach $2,860?
9514 1404 393
Answer:
21.6 years
Step-by-step explanation:
The first statement tells you the account balance can be modeled by ...
A = 440(2)^(t/8) . . . . . where t is in years
We want to find t when A = 2860
2860 = 440(2^(t/8))
6.5 = 2^(t/8) . . . . . . . . . . divide by 440
log(6.5) = (t/8)log(2) . . . . take logarithms
t = 8·log(6.5)/log(2) ≈ 21.604 . . . . . . divide by the coefficient of t; evaluate
It would take about 21.6 years for the value to reach $2,860.

Fixed expenses are $358,000 per month. The company is currently selling 5,300 units per month. The marketing manager believes that a $15,000 increase in the monthly advertising budget would result in a 190 unit increase in monthly sales. What should be the overall effect on the company's monthly net operating income of this change?
Answer:
Change in net operating income = $4,950
Step-by-step explanation:
Missing Detail;
Contribution margin = $105 per unit
Current selling unit = 5,300
Increase in monthly sale = 190 unit
Advertisement cost = $15,000
Find:
Change in net operating income
Computation:
Change in net operating income = [Contribution margin x Increase in monthly sale] - Advertisement cost
Change in net operating income = [105 x 190] - 15,000
Change in net operating income = [19,950] - 15,000
Change in net operating income = $4,950

It may be simplest just to try the answer choices.
We notice that y = x+3 is not satisfied by the points in choices A or D, so those can be eliminated.
__
The second equation can be written in vertex form as ...
y = (x -1)^2 -2
This equation is not satisfied by the points of choice B.
Using (-1, 4) (from choice B), we get 4 = (-1-1)^2 -2 = 4-2 = 2 . . . FALSE.
However it is a good match for the points of choice C.
Using (-1, 2) (from choice C), we get 2 = (-1-1)^2 -2 = 4 -2 = 2 . . . True
The appropriate choice is ...

Answer:
x = 29
Step-by-step explanation:
Given:
m<PQS = 107°
m<RQS = 49°
m<PQR = (2x)°
Required:
Value of x
Solution:
m<RQS + m<PQR = m<PQS (angle addition postulate)
Plug in the values
49 + 2x = 107
Subtract 49 from each side
2x = 107 - 49
2x = 58
Divide both sides by 2
x = 58/2
x = 29
Lalasa and Yasmin are designing a triangular banner to hang in the school gymnasium. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, what will the area of the actual banner be? A 52.5 ft2 B 17.5 ft2 39.375 ft2 D 78.75 ft2
Find the actual Dimensions of the triangle.
Multiply the size of the triangle on paper by 1.5 feet per inch:
Width = 5 x 1.5 = 7.5 feet.
Height= 7 x 1.5 =10.5 feet
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.
Answer: 39.375 square feet.
The area of the actual banner is 39.375 feet²
What is scaling?
Scaling is used to increase or decrease the size of a figure so as to create an image.
Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:
Base = 5 in * 1.5 feet per in = 7.5 feet
Height = 7 in * 1.5 feet per in = 10.5 feet
Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²
The area of the actual banner is 39.375 feet²
