What is the total surface area of the prisim
Answer:
A. 846 cm²
Step-by-step explanation:
1539 ÷ 19 = 81
√81 = 9
9 · 9 · 81 = 1539
A = 2(wl + hl + hw)
A = 2(19 · 9 + 9 · 9 + 9 · 19)
846 cm²

Jason, Lewis, and Nora will be placed in a line along with 7 other people.
What is the probability that they will be next to each other in any order?
Give percentage
Answer:
[tex]Pr = 6.67\%[/tex]
Step-by-step explanation:
Given
[tex]n = 10[/tex] i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
[tex]Total = n![/tex]
[tex]Total = 10![/tex]
If the three are to be next to each other,
First, we arrange the three
[tex]r_1 = 3![/tex]
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
[tex]r_2 =8![/tex]
So, the total arrangement, when they have to be next to one another is:
[tex]r = r_1 * r_2[/tex]
[tex]r = 3! * 8![/tex]
The probability is:
[tex]Pr = \frac{r}{n}[/tex]
[tex]Pr = \frac{3! * 8!}{10!}[/tex]
Expand
[tex]Pr = \frac{3*2*1 * 8!}{10*9*8!}[/tex]
[tex]Pr = \frac{3*2*1}{10*9}[/tex]
[tex]Pr = \frac{6}{90}[/tex]
[tex]Pr = 0.0667[/tex]
Express as percentage
[tex]Pr = 0.0667 * 100\%[/tex]
[tex]Pr = 6.67\%[/tex]

An online furniture store sells chairs for $150 each and tables for $600 each. Every day, the store can ship a maximum of 18 pieces of furniture and must sell at least $5400 worth of chairs and tables. If x represents the number of tables sold and y represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
13,500
Step-by-step explanation:
x + y = 750
750 x 18 = 13.500
The value of the number of tables will be 6 and the number of chairs will be 12.
How to form an equation?When trying to set up or construct a linear equation to fit a real-world application, identify the known quantities and use the unknown quantity as a variable.
In other words, an equation is a set of variables that are constrained through a situation or case.
From the question constraint of a maximum of 18 pieces of furniture
x + y =18
From the question constraint of at least $5400 worth of chairs and tables
600x + 150y ≥ 5400
By equation first, y = 18 - x put this into second
600x + 150(18 - x) ≥ 5400
450x ≥ 2700
x ≥ 6 hence there is need to sell at least 6 tables.
Put x =6 into x + y =18 then
y = 12 hence at least 12 chairs need to be sold.

The area of Kylie's room is 400 square feet. The width of her room is 20 feet. What is the length of her room?
Answer and Step-by-step explanation:
Assuming the room is a type of rectangle, we need to divide the area by the width to get the length.
So, do 400 divided by 20 to get the length, as length times width equals the area.
400 divided by 20 = 20.
The length of the room is 20 ft. (meaning the room is a perfect square.

Select all ordered pairs that satisfy the function y= -1/2x + 4 a) (-1, 3&1/2) b) (1, 3&1/2) c) (2&1/2, 3) d) (2, 3)
Answer:
The correct options are:
Option b) (1, 3 + 1/2)
Option d) (2,3)
Step-by-step explanation:
Suppose that we have a function:
y = f(x)
A ordered pair (a, b) satisfies this function if:
b = f(a).
In this case, the function is:
y = -(1/2)*x + 4
Let's try with each one of the options:
a) (-1, 3 + 1/2)
Replacing these values we get:
3 + 1/2 = -(1/2)*-1 + 4
3 + 1/2 = 1/2 + 4
3 + 1/2 = 4 + 1/2
This is false, then the point (-1, 3 + 1/2) does not satisfy the function.
b) (1, 3 + 1/2)
Replacing these values we get:
3 + 1/2 = -(1/2)*1 + 4
3 + 1/2 = 4 - 1/2 = (3 + 1) - 1/2 = 3 + (1 - 1/2) = 3 + 1/2
3 + 1/2 = 3 + 1/2
This ordered pair satisfies the function.
c) (2&1/2, 3)
Replacing these values we get:
3 = (-1/2)*(2 + 1/2) + 4
3 = -(1/2)*2 - (1/2)*(1/2) + 4
3 = -1 - 1/4 + 4
3 = 3 - 1/4
This is false, then the point (2 + 1/2, 3) does not satisfy the function.
d) (2, 3)
Replacing these values in the function we get:
3 = -(1/2)*2 + 4
3 = - 1 + 4
3 = 3
This is true, then (2, 3) satisfies the function.

What is the angle of elevation that is required for a hit ball to just clear the center field fence when it is hit 2 ft above the ground? Show all of your work and round your answer to the nearest hundredth of a degree.
I know the degree but I need to know how the degree was found. I am using the U.S Cellular Field, aka the Guaranteed Rate Field in Chicago, IL.
The distance from the home plate to the center-field fence is 400 ft. The height of the center field fence is 8 ft. The given angle of elevation is 0.86 degrees.
C is the point on the ground where the person is standing and which is making the angle of elevation of 60° AB (Height) = ? Example 2 :Height of tree is 8.65m, the angle of elevation of the top of tree is 60° find the distance at which the person is standing away from tree ? Solution : Let AB is the tree. B is the foot and A is the top of tree.
2 ft above
AB=10ftBC=400ftNow
Angle be x

What is the greatest common factor of 42 and 3
Answer:
3
Step-by-step explanation:
Prime factorize 42 and 3 and you'll eventually get 3 as your answer.
Answer:
3
Step-by-step explanation:
Since you are looking for the greatest common factor, 3 cant have many factors other than itself. So it would be 3, when simplified its similar to 42/3 and 3/3 where it would be 14 and 1.
5. Classify each triangle by its angle and sides
Answer:
5 is D
6 is C
Step-by-step explanation:
Define:
Equilateral - All sides and angles are congruent
Isosceles: Two congruent sides and two congruent angles
Scalene: No congruent sides or angles
Right triangle: A triangle with a right angle ( note that a right angle has a measure of 90 degrees )
obtuse triangle: A triangle with an obtuse angle ( obtuse angles have a measure of more than 90 degrees. )
Acute triangle : A triangle with an acute angle ( an acute angle has a measure of less than 90 degrees )
Answer:
the triangle shown in # 5 has a right angle and 2 congruent sides and angles
Therefore the triangle in #5 is a right isosceles
The triangle shown in #6 has an angle with a measure that is more than 90 degrees and have no congruent sides or angles therefore the triangle in #6 is an obtuse scalene.
