Step-by-step explanation:
Given the expression
[tex]\frac{3^9\times \:y}{2\times 81}[/tex]
solving the expression
[tex]\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}[/tex]
[tex]=\frac{3^9y}{3^4\times \:2}[/tex] ∵ [tex]162=3^4\times \:2[/tex]
[tex]=\frac{3^5y}{2}[/tex] ∵ [tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]=\frac{243y}{2}[/tex] ∵ [tex]3^5=243[/tex]

A group of 44 students is planning a train trip to Washington, D.C. They held many fundraisers and raised $10,880. Nathan said, “We should have enough money to pay for the train tickets. There are about 50 students going on the trip and one round trip ticket costs about $200. That makes the total cost of the tickets less than $10,000.” Does Nathan’s reasoning make sense?
Answer:
Yes
Step-by-step explanation:
Yes, Nathan's reasoning makes perfect sense because he is only stating that the money will be enough for the train tickets. Since a ticket for a single student is $200 round-trip and there are a total of 50 students going then that would mean that the total cost is indeed $10,000 (200 * 50). Since they raised a total of $10,880 with the fundraisers that would leave them with $880 ($10,880 - $10,000) after buying all the tickets that they need for all of the students.

You need a front and back (same size for them as well)
You need a left and right covering.
Top and bottom = 2 * 12.6 * 8 = 201.6
Left Right = 2 * 8 * 2 = 32.0
Front/Back= 2 * 2 * 12.6 = 50.4

Step-by-step explanation:
for x=5 for x=1/5
Apply;fraction:cross:multiply: 8/12=10/3 x then switch sides
8*3x =12*10 10/3 x = 8/12 cancel the common factor:4
simplify: 10/3 x = 2/3
24x=120 multiply both sides by 3
divide both sides by 24 3*10/3 x = 2*3/3
24x/24=120/24 simplify: 10x =2
simplified =5 divide both sides by 10: 10x/10=10/2
x=5 simplified = 1/5
x=1/5

What single decimal multiplier would you use to increase by 4% followed by a 4% decrease?
Answer:
if you increase by 4%, it means you will have a new total of 104%. In decimals it is 1.04 (divide your percentage by 100) after that you do the same with the 3% increase. you'll have a new total of 103%. In decimals 1.03. If you want to know what single multiplier you can use, you need to multiply the both decimals. So you get 1.04 x 1.03 = 1.0712
Step-by-step explanation:
The decimal multiplier would you use to increase by 4% followed by a 4% decrease is 1.0816.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
We have to find decimal multiplier would you use to increase by 4% followed by a 4% decrease.
So, (1+ 4%)(1+ 4%)
= (1 + 4/100)(1 + 4/100)
= (1 + 0.04)(1+0.04)
= 1.04 x 1.04
= 1.0816

Step-by-step explanation:
Martin decided to buy 2 bags of grapes weighing 5 and two-thirds pounds each, instead of the 3 bags weighing 4 and one-fifth pounds each, because the bigger bags were on sale. Did he end up with more grapes or less grapes by buying the bigger bags? He ended up with about One-half pound less grapes. He ended up with about One-half pound more grapes. He ended up with about 1 pound less grapes. He ended up with about 1 pound more grapes.
Answer: He ended up with about 1 pound less grapes
Step-by-step explanation:
2 bags of grapes weighing 5 and two-thirds pounds each will give a total weight of:
= 2 × 5 2/3
= 2 × 17/3
= 34/3
= 11 1/3 pounds
3 bags weighing 4 and one-fifth pounds each, will give a weight of:
= 3 × 4 1/5
= 3 × 21/5
= 63/5
= 12 3/5
He ended up buying lesser grapes. This was about 12 3/5 - 11 1/3 = 1 4/15 less. This means that he ended up with about 1 pound less grapes

Write an equation of the line passing through point P that is perpendicular to the given line.
P(6, 10), y = -3x + 13
Answer:
y = 1/3x + 8
Step-by-step explanation:
1. Find slope of y = -3x+13
(m = -3)
2. Compute slope for perpendicular line
(m = 1/3)
basically, to find the perpendicular slope, you swap the numerator and denominator of your slope and swap it from negative to positive. (If you started with a positive slope it would turn negative)
3. Find the line with slope m=1/3 that passes through (6,0)
(y = 1/3x + 8)
which expression is equivalent to x2-17x-60
Answer:
(x - 20)(x + 3)
Step-by-step explanation:
Multiply the coefficient of the first term. 1 x -60
which equals -60
find the two factors of -60 which is -17
-60+ 1 = -59
-30+ 2= -28
-20+ 3= -17
Then, the final answer you will get is (x - 20)(x + 3)

A regular octagon is a shape with 8 congruent sides.
The minimum angle of rotation is 45 degrees
The number of sides of a regular octagon is:
[tex]\mathbf{n = 8}[/tex]
The total angle at the center of the regular octagon is:
[tex]\mathbf{\theta = 360}[/tex]
So, the minimum angle of rotation is calculated as follows:
[tex]\mathbf{\alpha = \frac{\theta}{n}}[/tex]
This gives
[tex]\mathbf{\alpha = \frac{360}{8}}[/tex]
[tex]\mathbf{\alpha = 45}[/tex]
Hence, the minimum angle of rotation is 45 degrees

Answer:
The coordinates that satisfy the equations will be: (3, 2)
Hence, option C is correct.
Step-by-step explanation:
Given the equations
[tex]x\:-2y\:=-1;\:2x\:+\:3y=12[/tex]
solving the equations to find the solution values (coordinates)
[tex]\begin{bmatrix}x-2y=-1\\ 2x+3y=12\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}x-2y=-1\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2x-4y=-2[/tex]

[tex]7y=14[/tex]
[tex]y=2[/tex]
[tex]\mathrm{For\:}2x-4y=-2\mathrm{\:plug\:in\:}y=2[/tex]
[tex]2x-4\cdot \:2=-2[/tex]

You have a bag of 12 marbles. Four are blue, 6 are green, 2 are red, and the others are yellow. What is the probability of drawing a red marble and, without replacing it, then drawing a green marble?
Answer:
[tex]Probability = \frac{1}{11}[/tex]
Step-by-step explanation:
Given
[tex]Blue = 4[/tex]
[tex]Green = 6[/tex]
[tex]Red = 2[/tex]
[tex]Total = 12[/tex]
Required
Determine the probability of drawing red and green without replacement
This is calculated as follows:
[tex]Probability = P(Red\ and\ Green)[/tex]
[tex]Probability = P(Red)\ and\ P(Green)[/tex]
[tex]Probability = \frac{n(Red)}{Total} * \frac{n(Green)}{Total - 1}[/tex]
We used Total - 1 because it's a probability without replacement:
[tex]Probability = \frac{2}{12} * \frac{6}{12- 1}[/tex]
[tex]Probability = \frac{2}{12} * \frac{6}{11}[/tex]
[tex]Probability = \frac{1}{6} * \frac{6}{11}[/tex]
[tex]Probability = \frac{1}{11}[/tex]
Hence, the required probability is 1/11

Answer:
to find the ammount of twine left we subtract (twine used) from (total twine) or (total twine)-(twine used)=ammount left
so he must cut 42 legnths of rope each legnth is 4.75 and this is taken from a
total legnth of 240 so
240-42(4.75)=amount left
