Prism A is a triangular prism. The triangular base has a base of 7 meters and height of 9 meters. The prism has a height of 4 meters. Prism B is a rectangular prism with length of 8 meters, width of 2 meters, and height of 8 meters.
Which prism has the least volume?
Prism ________
Answers
Answer:
A
Step-by-step explanation:
Prism A Volume
The Column of Prism A = Base (Area) * Height.
I think you have to assume that the triangle is a right triangle.
Area of the triangle = 1/2 * 9 * 7
Area of the triangle = 1/2 63
Area of the triangle = 31.5
Volume of the Prism = area of the triangle * thickness
Volume of the prism = 31.5 * 4
Volume of the prism = 126 m^3
Prism B = L * w * h
Prism B = 8 * 8 * 2
Prism B = 128
Prism A has the least volume by just a little.
Answer:
Prism A has the least volume

1) x² + x + 3 = 0 use the discriminant to tell whether the equation has two solution
Answers
Answer:
The equation does not have any real solutions.
The equation only has two imaginary solutions.
Step-by-step explanation:
Step 1
Use Discriminant to check how many solutions does the equation have.[tex] \large{D = {b}^{2} - 4ac}[/tex]
Let a = 1, b = 1 and c = 3 from the given equation.
[tex]D = {(1)}^{2} - 4(1)(3) \\ D = 1 - 12 \\ D = - 11[/tex]
Since the value of D is in negative. Therefore, the equation does not have any solutions.
Discriminant
[tex]D > 0 \longrightarrow \sf{two \: \: real \: \: solutions} \\ D = 0 \longrightarrow \sf{one \: \: real \: \: solution} \\ D < 0 \longrightarrow \sf{two \: \: imaginary \: \: solutions} [/tex]

Whenever you're given an inverse trig function like this, think "tangent of what gives me -1?" There are multiple ways in which you can solve this; knowing how tangent work, guess checking sin/cos to get -1, or using a calculator. The only way tangent can be an integer is if the sine and cosine of the angle are equal.

Which sentence is an example of an objective summary from Cynthia Crossen's "A Culinary Wasteland"?
A. Furthermore, Mr. Schlosser's appraisal is not comprehensive but a hodgepodge of impressions, statistics, anecdotes and prejudices.

A rectangular garden has a width of 10 feet and a length of 14 feet. A cement walkway is added around the outside of the garden. The area of the garden and the walkway together are 320 square feet. What is the width of the walkway
Answers
Answer:
The width of the walkway is of 12.86 feet.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle of length l and width w is given by:
A = lw
A rectangular garden has a width of 10 feet and a length of 14 feet.
So the area of the rectangular garden is of 10*14 = 140 square feet.
The area of the garden and the walkway together are 320 square feet.
So the area of the walkaway is of 320 - 140 = 180 square feet.
What is the width of the walkway
It has the same length of the garden, of 14. So
[tex]14w = 180[/tex]
[tex]w = \frac{180}{14}[/tex]
[tex]w = 12.86[/tex]
The width of the walkway is of 12.86 feet.

To make an international telephone call, you need the for the country you are calling. The codes for country A, country B, and C are three consecutive integers whose sum is 90. Find the code for each country.
Answers
Answer: 3 consecutive integers
x = 1st integer (country A)
x + 1 = 2nd integer (country B)
x + 2 = 3rd integer (country C)
whose sum is 114
x + (x + 1) + (x + 2) = 114...combine like terms
3x + 3 = 114
3x = 114 - 3
3x = 111
x = 111/3
x = 37 <== country A
x + 1 = 37 + 1 = 38 <==country B
x + 2 = 37 + 2 = 39 <== country C
Step-by-step explanation:
Answer:
29, 30, 31
Step-by-step explanation:
(x) + (x+1) + (x + 2) = 90
3x + 3 = 90
x = 29
(29) + (30) + (31) = 90

At the not much fun amusement park, Otaka Shawa paid $25.75 for three game of mini-marbles-golf and two rides on the slow-go-karts,while Soren Derkeister paid $35.75 for four games of mini-marbles-golf and three rides on the slow-go-karts. How much did each activity cost?
Answers
3m + 2g = 25.75
4m + 3g = 35.75
We’ll take the top equation and solve for g in terms of m.
2g = -3m + 25.75
g = (-3m + 25.75)/2
Then substitute that mess, um, expression, I to the second equation to solve for m.
4m + 3[(-3m + 25.75)/2] = 35.75
4m + (-9m + 77.25)/2 = 35.75
4m -4.5m + 38.625 = 35.75
-0.5m = -2.875
0.5m = 2.875
m = 5.75
Now we pick an equation, plug in the numerical value of m, and solve for a numerical value of g
3m + 2g = 25.75
3(5.75) + 2g = 25.75
17.25 + 2g = 25.75
2g = 8.50
g = 4.25
Checking the math:
4m + 3g = 35.75
4(5.75) + 3(4.25) = 23 + 12.75 = 35.75
Mini marbles golf cost $4.25, slow go karts cost $5.75.

write the following sets in explicit form and determine the cardinality of
each set.
a) μ = {x: x is a positive counting number less 25}
Answers
Answer:
As the givens set μ has 24 elements.
Therefore,
Cardinality = 24Step-by-step explanation:
Given
μ = {x: x is a positive counting number less 25}
The set of natural numbers is often termed as the Counting number set.
As the counting numbers are less than 25.
Thus, the set μ is:
μ = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}
We know that cardinality of the set is the number of elements in a given set.
As the givens set μ has 24 elements.
Therefore,
Cardinality = 24Put the expressions in order from least to greatest value
Answers
Answer:
Least: [tex]\sqrt[6]{64}[/tex]
2nd least: ([tex]\sqrt{64}[/tex])²
2nd greatest: [tex]\sqrt{81}[/tex] · [tex]\sqrt{81}[/tex]
Greatest: 1/64^-2
Step-by-step explanation:
[tex]\sqrt[6]{64}[/tex] = 2
([tex]\sqrt{64}[/tex])² = 64
[tex]\sqrt{81}[/tex] · [tex]\sqrt{81}[/tex] = 9 · 9 = 81

Answers
The given question is incomplete. The complete question is:
A force of 90 Newton's is applied to a [tex]20cm^2[/tex] surface. The force applied is then increased by 5 Newton's and the surface is increased by [tex]5cm^2[/tex]. What percentage does the outcome decrease by
Answer: The outcome decreases by 15.5 %
Step-by-step explanation:
Pressure is defined as the ratio of force per unit area.
[tex]Pressure=\frac{Force}{Area}[/tex]
Case 1: [tex]P_1=\frac{90N}{20cm^2}=4.5Ncm^{-2}[/tex]
Case 2: [tex]P_2=\frac{95N}{25cm^2}=3.8Ncm^{-2}[/tex]
Decrease in pressure = [tex]P_1-P_2[/tex] = [tex](4.5-3.8) Ncm^{-2}=0.7Ncm^{-2}[/tex]
Percentage decrease = [tex]\frac{0.7}{4.5}\times 100\%=15.5\%[/tex]
Thus the outcome decreases by 15.5 %
