Find the side of an equialateral triangle if it's area is 9√3 cm2
Step-by-step explanation:
We know that the area of an equilateral triangle of side a cm is
[tex] \rm \: Equilateral \: Triangle = \cfrac{ \sqrt{3} }{4} {a}^{2} \: cm[/tex]Let a cm here be 9√3 then we could get our solution.
[tex] \rm\implies \rm 9 \sqrt{3} = \cfrac{ \sqrt{3} }{4} \: a {}^{2} [/tex]
[tex] \implies \rm \: \cfrac{ \sqrt{3} }{4} {a}^{2} = 9 \sqrt{3} [/tex]
[tex] \implies \rm \: a {}^{2} = 36[/tex]
[tex] \implies \rm \: a = \sqrt{36} = \sqrt{6 \times 6} [/tex]
[tex] \implies \rm \: a = 6 \: cm[/tex]
Thus, the side of the equilateral triangle is 6 cm.

A cake has two layers. Each layer is a regular hexagonal prism. You cut and remove a slice that takes away one face of each prism as shown. What is the volume of the slice? What is the volume of the remaining cake? Use pencil and paper. Describe two ways to find the volume of the slice.
P.S. pls help me
The volume of the slice is 40 in³. The volume of the remaining cake is 197.014 in³.
What is a regular hexagon?A regular hexagon is defined as a closed shape consisting of six equal sides and six equal angles.
Here we have two regular hexagons
one top small hexagon cake with side length = 3 in, height = 3 in
One big hexagon cake, side length = 4 in, Height = 4 in
A slice cut such that it removes a side segment is equivalent to an equilateral triangle with side length = length of hexagon side
Also, all angles within the equilateral triangle are 60° each
Therefore, the length of the side of the removed equilateral triangle side
Top small cake slice triangle side = 3 in.
Area of surface of small slice = 1/2 x b x h = 1/2 x 3 x 3 x sin 60
= 9√3/ 4
The volume of a small slice
= Area of surface small slice × Height of small cake
= 9√3/ 4 x 3
= 11. 69
Big cake slice triangle side = 4 in.
Area of the surface of big slice = 1/2 x 4 x 4 x sin 60
= 4√3
The volume of big slice = Area of surface of big slice × Height of big slice
= 16√3
= 28
Total volume of slice = Volume of small slice + Volume of big slice
Total volume of slice = 12 in³ +28 in³ = 40 in³
For the small cake, the remaining volume = 5 x 11.69 = 58.45
For the big cake the remaining volume = 5 x 27.71 = 138.56
Total volume remaining cake = 58.45 in³ + 138.56 in³ = 197.014 in³
a = Length of side
h = Height of hexagon
The volume of each slice is, therefore,
= a^2 x h x √3/4
For the small cake, we have
a = 3 in.
h = 3 in.
Volume of small slice = a^2 x h x √3/4
= 9 x 3 x √3/4 = 27√3/4
For the big cake, we have
a = 4 in.
h = 4 in.
Volume of big slice = a^2 x h x √3/4
= 16 √3
The total volume of slice = Volume of small slice + Volume of a big slice
Total volume of slice = 27√3/4 + 16 √3
The total volume of slice = 39404 in³.

(-1,-4) and (-201,-49)
Find the distance between the two points
Answer:
205 units
Step-by-step explanation:
The distance formula is D = √(x2-x1)^2 + (y2-y1)^2
Lets say -1 is x1 ; -4 is y1; -201 is x2 ; and -49 is y2
we just need to plug it into the formula and solve now
√ (-201 - -1)^2 + (-49 - -4)
√-200^2 + -45^2
√40000 + 2025
√42025 = 205
The distance between the two points is 205 units.

A graph shows the number of texts, numbered 10 to 100, on the x-axis, and the total cost in dollars, numbered 3 to 27, on the y-axis. A straight red line with a positive slope, labeled Emilia, begins at (0, 10), and a straight blue line with a positive slope, labeled Hiroto, begins at (0, 20). Both lines intersect at point (50, 22.5).
Hiroto’s texting plan costs $20 per month, plus $0.05 per text message that is sent or received. Emilia’s plan costs $10 per month and $0.25 per text. Using the graph below, which statement is true?
Hiroto’s plan costs more than Emilia’s plan when more than 50 texts are sent.
Both plans cost the same when 22 texts are sent.
Emilia’s plan costs more than Hiroto’s plan when more than 22 texts are sent.
Both plans cost the same when 50 texts are sen
Answer: Both plans cost the same when 50 texts are sent.
Step-by-step explanation:
When x=50 (meaning 50 texts are sent), the y coordinate (which represents the cost) is the same.

i) Calculate the number of people like black coffee?
ii) How many people don’t like any of the drinks?
Answer:
32
Step-by-step explanation:
Answer:
i) 52
ii) 66
Step-by-step explanation:
This sort of problem is usually solved using some sort of table or Venn diagram. We have used a table in the attachment such that each of the cells in the grid represents one of the 8 possible combinations of coffee, tea, or chocolate.
The numbers in black are given directly by the problem statement. The numbers in blue are calculated from the numbers in black and one of the other given numbers in the problem statement. The numbers in red are calculated so the totals work out correctly.
The cells shaded blue-gray are "one and only one" of the drinks. The cell shaded purple-gray is "don't like any".
__
i) black coffeeWe assume that any form of "coffee" is "black coffee." The problem statement tells us 52 people like coffee.
__
ii) noneThe last number we calculated is the number who like none of the drinks: 66. This brings the total of non-coffee drinkers to 148.
_____
Additional comment
As noted above, the colors more or less indicate the order of the calculations. We started with 36 who like coffee only, and 46 who like coffee and not tea. That means 46-36=10 like coffee and chocolate, but not tea.
Since 16 like coffee and chocolate, that leaves 16-10=6 who like coffee and tea and chocolate (all three).
96 like chocolate, but 16 of those like chocolate and tea. The other 80 like chocolate, but not tea.
46+16=52, so there must be 0 who like coffee and tea, but not chocolate.
The number who like only one is 108. We already have 36 that are coffee only, 80-10 = 70 that are chocolate only, so there must be 108 -70 -36 = 2 who like tea only.
Now, we can finish filling the top row of the table and the totals in the bottom row.

A.If a, b, and c are real numbers, then a = b.
B.For all real numbers a, b, and c, if a−c=b−c, then a = b.
C.For all real numbers a, b, and c, if a = b, then a−c=b−c.
D.If a, b, and c are real numbers, then a−c=b−c.
The conditional proposition for the given sentence is:
"For all real numbers a, b, and c, if a = b, then a−c=b−c."
Which one is a conditional statement?
A conditional statement is of the form:
If P, then Q.
Where P and Q are two propositions.
The sentence is:
"For all real numbers a, b, and c, a = b implies that a−c=b−c."
So the propositions are:
P = "a = b"
Q = " a - c = b - c"
Where we need to define that this works for all real numbers.
So the conditional proposition is:
"For all real numbers a, b, and c, if a = b, then a−c=b−c."
So the correct option is C.

What is the future value of a 5-year annuity due with annual payments of $ 2,535 , evaluated at a 14.18 percent interest rate? Enter your answer to the nearest $.01. Do not use $ or , signs in your answer. Enter your answer as a positive number.
Answer:
$19,201.09
Step-by-step explanation:
The future value of the annuity due can be found using any of a number of apps, calculators, or spreadsheets. It can also be found using the formula ...
A = P(1 +r)((1 +r)^n -1)/r
where P is the annual payment, r is the annual interest rate, and compounding is yearly for n years.
A = 2535(1.1418)(1.1418^5 -1)/0.1418 ≈ 19,201.09
The value will be $19,201.09.

The load requirement in your plan is 60 psf at a joist spacing of 16 inches . If the room dimensions are length 13 feet 2 inches and width 11feet 7 inches are 2 by 10 boards appropriate
The correct answer is; No, because the 2 x 10 boards can support neither the width nor length of the room.
How to find the dimensions?
We are given;
Load requirement = 60 psf
Joist Spacing = 16 inches
Length of room; 13 feet 2 inches
Width of room; 11 feet 7 inches.
Since we want to consider whether 2 by 10 boards are appropriate, this length of 2 by 10 will not be appropriate because it cannot cover up for a room with dimensions of 13 feet 2 inches and 11 feet 7 inches.
Thus, we can conclude that No, because the 2 x 10 boards can support neither the width nor length of the room.
The missing options are;
A. Yes, because 2 x 10 boards can support the width and length of the room
B. Yes, because 2 x 10 boards support the 70 psf
C. No, because 2 x 10 boards can support only the width of the room
