Bobby hit the wrong lever and as a result the factory produced way too many cheese puffs. If the factory managers decide to to give away 1/3 of 1/9 of a ton away as samples, what fraction of a ton did they give away? Make sure you answer is fully reduced.
Given:
The factory managers decide to to give away [tex]\dfrac{1}{3}[/tex] of [tex]\dfrac{1}{9}[/tex] of a ton away as samples.
To find:
what fraction of a ton did they give away?
Solution:
According to the question, the factory managers decide to to give away [tex]\dfrac{1}{3}[/tex] of [tex]\dfrac{1}{9}[/tex] of a ton away as samples. So,
[tex]\text{Samples}=\dfrac{1}{3}\left(\dfrac{1}{9}(1\text{ ton})\right)[/tex]
[tex]\text{Samples}=\dfrac{1}{3}\times \dfrac{1}{9}\times (1\text{ ton})[/tex]
[tex]\text{Samples}=\dfrac{1}{27}\times (1\text{ ton})[/tex]
[tex]\text{Samples}=\dfrac{1}{27}(1\text{ ton})[/tex]
So, samples is [tex]\dfrac{1}{27}[/tex] of a ton.
Therefore, they give away [tex]\dfrac{1}{27}[/tex] of a ton as samples.

Solve : 4/x-3 + 2/x-2 = 6/x
Answer:
x = [tex]\frac{9}{4}[/tex] or 2.5
Step-by-step explanation:
[tex]\frac{4}{x-3} + \frac{2}{x-2} = \frac{6}{x}[/tex]
Finding L.C.M. of (x - 3) and (x - 2)
[tex]\frac{4(x-2) + 2(x-3) }{(x-3)(x-2)} = \frac{6}{x}[/tex]
[tex]\frac{(4x-8) + (2x-6)}{x^{2} - 3x-2x+6}=\frac{6}{x}[/tex]
[tex]\frac{4x-8 +2x-6}{x^{2} -5x +6} = \frac{6}{x}[/tex]
[tex]\frac{6x-14}{x^{2} -5x+6}= \frac{6}{x}[/tex]
Cross multiplying:
x (6x - 14) = 6 (x² - 5x +6)
6x² - 14x = 6x² - 30x + 36
Cancelling 6x² from both the sides:
- 14x = - 30x + 36
30x - 14x = 36
16x = 36
x = [tex]\frac{36}{16}[/tex]
∴ x = [tex]\frac{9}{4}[/tex] or 2.5
Which of the following represents the relationship between the circumference, c, and diameter, d, of any circle?
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is
[tex]C=2\pi r[/tex]
It can be written as
[tex]C=(2r)\pi [/tex]
[tex]C=d\pi [/tex] [tex][\because d=2r][/tex]
On dividing both sides by d, we get
[tex]\dfrac{C}{d}=\pi [/tex]
Therefore, the correct option is (F).

Solving this expression:
6x + 1 - 3x +1
Collect like terms
6x - 3x +1 +1
3x + 2
Hence, the expression that are equivalent to 3x + 2 are:
c. 3x+2( 3 x plus 2 )
d. 6x−3x+1−1(6 x minus 3 x plus 1 minus 1)

the ratio of the number of left-handed batters in a team to the number of right -handed batters was 5 : 8 there were 45 left-handed batters .
\
a) how many right-handed batters were there?
b) find the ratio of the number of left- handed batters to the total number of batters express youe=r answer in simplest form
Answer:
72 right handed batters.
Step-by-step explanation:
45/5=9
8*9=72
45:72=5:8
Hope this helps.
Answer:
a) 72 right-handed batters
b) 5:13
Step-by-step explanation:
This is the answer because:
1) For problem a, we can see that 5 x 9 = 45. In order to balance the ratio, we also have to mulitply the 8 with a 9:
8 x 9 = 72
Therefore, the answer is 72 right-handed batters.
2) For b, there are two ways to do it. Sine we know that there are 5 left-handed batters, we just add 5 + 8 = 13. Therefore, the simplest form of the ratio is 5:13. Another we can do it is by adding 45 + 72 = 117 (total batters). Then, 45 of them are left-handed batters which means the ratio is 45:117 = 5:13.
Therefore, the answer is 5:13.
Hope this helps! :D
Which pair of angles are vertical angles?
/_ZRQW and /_ZWQV
/_ZRQT and /_ZTQV
/_ ZRQW and /_ZTQU
/_ZRQS and /_ZSQU
Answer:
(c) is correct.
Step-by-step explanation:
When two lines cross each other, the angles opposite to each other are called vertically opposite angles. They are always equal.
In this given figure,
Line TW and RU cross each other at Q, it means
[tex]\angle RQW=\angle TQU[/tex] (vertically opposite angles)
Hence, the correct option is (c).

Jessica and Raphael are saving money for concert tickets. Each friend starts with an amount and also saves a specific amount each week.
Jessica came up with the following equation to show the total, y, she has saved at the end of each week, x.
y = 10x + 20
Raphael created a table to show the total he has saved at the end of each week.
Weeks 0 1 2 3 4 5 6 7 8
Amount saved 40 46 52 58 64 70 76 82 88
After saving for a certain number of weeks, Jessica and Raphael will have each saved the same amount of money. How much money will they have each saved then?
Compare the rate at which each friend saves money.
Select the correct answer from the drop-down menu to complete the statement.
The rate at which Jessica is adding to her savings each week is $
1,4,6,8,or 10
more than the rate at which Raphael is adding to his savings each week.
Answer:
part 1: Jessica saved 100, Raphael saved 88
part 2: The rate at which Jessica is adding to her savings each week is $4 more than the rate at which Raphael is adding to his savings each week.
Step-by-step explanation:
First figure out how much money Jessica saved at the end of week 8, compared to Raphael.
Use x =8
y = 10*8 + 20 = 100
For Raphael it is shown in the table as 88.
Next figure out the rate Raphael saves. We can find the slope usng (y2-y1) / (x2-x1).
Using the table lets use (0,40) and (1,46)
46-40 / 1-0 = 6/1 = 6
So Raphael saves $6 each week. This is $4 less than what Jessica saves each week since the slope for her equation is 10 or $10 each week.
please give thanks :)

A walking path at a park is 3/5 miles long. Paola walks on this path, completing each lap in 1/25 of an hour. What is Paola's running speed, including a unit of measure?
Answer:
15miles//hr
Step-by-step explanation:
From the question, we are given;
Distance covered by Paola = 3/5 miles
Time = 1/25 of an hour
Speed = Distance/ time
Substitute
Speed = (3/5)/(1/25)
Speed = 3/5 * 25/1
Speed = 3 * 5
Speed = 15
Hence Paola's running speed in miles per hour is 15miles/hr
