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

Answer:

It is C ( look down for proof)

Step-by-step explanation:

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.

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:

[tex]9^{-36}[/tex]

Step-by-step explanation:

Answer:

The simplified expression is:

[tex]\frac{3^9y}{2\times \:81}=\frac{243y}{2}[/tex]

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]

Therefore, the simplified expression is:

[tex]\frac{3^9y}{2\times \:81}=\frac{243y}{2}[/tex]

Answer:

284mm²

Step-by-step explanation:

S.A.= 2(lw) + 2(lh)+ 2(wh)

2[12.6(8)] + 2[12.6(2)] + 2[8(2)]

201.6 + 50.4 + 32

S.A.= 284mm²

Answer:

B

Step-by-step explanation:

You need a top and bottom (same size)

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

Total                                            284

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

42 trimes 4.75=199.5

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:

(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

We conclude that the list which

shows values in order from LEASE to GREATEST is:

Step-by-step explanation:

Given the values

[tex]\sqrt{30}=5.477[/tex]

[tex]\frac{49}{16}=3.0625[/tex]

[tex]\frac{80}{19}=4.210[/tex]

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]2x+3y=12[/tex]

[tex]-[/tex]

[tex]\underline{2x-4y=-2}[/tex]

[tex]7y=14[/tex]

so

[tex]\begin{bmatrix}2x-4y=-2\\ 7y=14\end{bmatrix}[/tex]

solve for y

[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]

[tex]2x=6[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}2[/tex]

[tex]\frac{2x}{2}=\frac{6}{2}[/tex]

[tex]x=3[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]x=3,\:y=2[/tex]

Therefore, the coordinates that satisfy the equations will be: (3, 2)

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)

Answer:

Step-by-step explanation:

[tex]y = 2x^2 - 4x + 5\\\\y = 2(x^2 - 2x) + 5\\\\y=2(\underline{x^2-2\cdot x\cdot1+1^2}-1^2)+5\\\\y=2\big[(x-1)^2-1\big]+5\\\\y=2(x-1)^2-2+5\\\\y=2(x-1)^2+3\quad\implies\quad vertex:\ (1\,,\ 3)[/tex]
