Answer:

Simplify and solve and get x=-5

Step-by-step explanation:

2/3x - 1/2= 1/3 + 5/6x

2/3x - 5/6x= 1/3 + 1/2

-1/6x= 5/6

x=-5

Answer:

The remainder of 11 divided by 3 is 2. The quotient is 3.

Step-by-step explanation:

3 goes into 11 three times. 3 x 3 = 9. 11 - 9 = 2. 3 can't go into 2 so bring the two up and you get your answer of 3 r 2.

what is the acceleration of a car that has a mass of 300 kg and 1200N

Answer:

well the acceleration produced will be

[tex]4ms { - }^{2} [/tex]

Step-by-step explanation:

the formula used here is

F = m × a

(where m = mass , a = acceleration and f = force )

so,

=》1200 N = 300 kg × a

=》a = 1200N ÷ 300 kg

=》a = 4 metre per second square

Answer:

Step-by-step explanation:

B 15%

Answer: The correct answer is D) 37%

Step-by-step explanation:

We can use our binomial model equation with all the relevant information to solve this problem simply. We just need to dissect the problem a bit to find relevant information. We know that out of 16 batteries in a pack (the number of trials in this case) we want to find the possibility of 1 of them (the number of successes) to be defective with a defective rate of 5% or 0.05. We simply input the data into our binomial formula given and solve for our answer of 37% I hope this answer has been of use.

Answer:

They are equal

Step-by-step explanation:

Given

[tex]\frac{3}{27}\ and\ \frac{1}{9}[/tex]

Required

Determine if they are equal

We start by equating both:

[tex]\frac{3}{27} = \frac{1}{9}[/tex]

Cross Multiply

[tex]3 * 9 = 1 * 27[/tex]

[tex]27 = 27[/tex]

Because both sides of the equation are equal, then the ratios are equal

Answer:

a) 265 case

b) 4 bottles

Step-by-step explanation:

The number of bottles remaining = total number of bottles - total number of bottles placed in cases

The number of bottles remaining = 8500 - 2136

The number of bottles remaining = 6364 bottles

From the table, we can see that water is filled at 24 bottles per case. Let x be the number of cases, hence:

24 bottles  per case * x case = 6364 bottles

24x = 6364

x = 6364

x = 265.16

Therefore the number of cases filled = 265.

265 cases can contain 6360 bottles

b) number of bottles remaining = 6364 bottles - (24 * 265 case) = 4 bottles

Answer:

There are 17.4 minutes of commercials are shown each hour.

Step-by-step explanation:

An hour has 60 minutes.

So in 3 hours, there are 3*60 = 180 minutes.

The commercials show 29% of the time.

So we have 0.29*180 = 52.2 minutes, in total, of commercial.

Per hour, we have 52.2/3 = 17.4 minutes of commercial.

Answer:

Denpeds on the left hand side of nagetive of the inequality sign

Answer:

1. The slope of the graph is 3/1 or 3

2. The slope of the graph is 3/4

3. The slope of the points is 2

4. The slope of the points is Undefined

5. The slope of the graph is 1

6. The slope of the points is -1/4

Step-by-step explanation:

To find the slope of the graph you use rise over run

To find the slope of the points you use y2-y1 over x2-x1

Answer:

1. -1/3

2. 3/4

3. 2

4. -9/0

5. 1

6. -6/4

Step-by-step explanation:

1.  To find this numbers slope you have to go over and up (or down depending on where the line is going) You go over once and down three times to the next dot. This is why it is negative, because you go down

2. Same as number one you go over (Run) and up (Rise) . You go over 3 times and up 4. This makes it positive, since you are going up.

3.  Stick to this formula (y2-y1)

                                       (x2-x1)

-4-8

0-6     =-12/-6 =2

4. Same as 3

1-8

5-5     = -9/0

5.  Go over 1 and up 1 this will equal 1/1 which is just 1.

6.  

-2-4

-6-2   =-6/-8

This can be simplified down to -3/-4
