How many solutions can be found for the equation 5x 3(x − 1) = 10x − 2x − 3? None One Two Infinitely many.

Answer:

13

Step-by-step explanation:

The probability of a student chosen plays a sport is [tex]\frac{6}{27}[/tex]

'Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.'

According to the given problem,

Total number of students = 27

Number of students playing a sport = 6

Number of students playing an instrument = 12

Number of students no playing a sport or instrument = 13

Probability = [tex]\frac{No of possible events}{Total number of students}[/tex]

                  = [tex]\frac{6}{27}[/tex]

Hence, we can conclude that the probability of a student chosen plays a sport is [tex]\frac{6}{27}[/tex].

Answer:

Manager = 24

Kirk = 28

Brian = 36

Matt =18

Step-by-step explanation:

Let

The managers age = x

Kirk is twice ten years less than the manager's age

Kirk = 2(x - 10)

Brian is 12 years younger than twice the manager's age

Brian = 2x - 12

Matt is 6 years older than half the

manager's age.

Matt = 1/2x + 6

Total = 106 years

Add the four employees ages

x + 2(x-10) + (2x-12) + (1/2x + 6) = 106

x + 2x - 20 + 2x - 12 + 1/2x + 6 = 106

5x + 1/2x - 26 = 106

10x+x/2 = 106 + 26

11/2x = 132

x = 132 ÷ 11/2

= 132 × 2 / 11

= 264 / 11

= 24

x = 24

Managers age = x = 24 years

Kirk = 2(x - 10)

= 2(24 - 10)

= 2(14)

= 28 years

Brian = 2x - 12

= 2(24) - 12

= 48 - 12

= 36 years

Matt = 1/2x + 6

= 1/2(24) + 6

= 12 + 6

= 18 years

Step-by-step explanation:

2:5 is the ratio for this problem. Divided 2 by 2 and divide 5 by 2. 1:2.5. Next, do 6.5 x 2.5.

The ratio of the volume divided by the temperature for the first data pair is 0.0026 using the significant figures.

The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.

The value of the volume is 0.72 and the value of temperature is 276 for the first data pair. The image of all the values of the volume and temperature table is attached below.

The ratio of the volume to the temperature is,

[tex]\dfrac{V }{ T} =\dfrac{ 0. 72}{276 }\\\dfrac{V }{ T} =0.002608695652[/tex]

The above value is the ratio of volume to the temperature. Now this value has to be written with significant figure.

Let's correct the value, after the 4 places of the decimal point. As the value of fifth place is zero, then the value of 4 place will remain as it is.

Thus, the ratio is,

[tex]\dfrac{V }{ T} =0.0026[/tex]

The ratio of the volume divided by the temperature for the first data pair is 0.0026 using the significant figures.

Answer:

Angle E is 54* and Angle F is 126* , Angle d is 90*

Step-by-step explanation:

Answer:

So you have the ratio of

1 : 2 : 5

Soda water : fruit punch: ginger ale

You have to make 32 pints of this.

You can add up the ratio.

1 + 2 + 5 = 8

You’d have 8 ingredients in total.

32 pints so 32/8 = 4

Now you have each ingredient *4

1 * 4 = 4
2* 4 = 8

5* 4 = 20

SO 4 soda water, 8 fruit punch, 20 ginger ale.

To check you can add these up again and if they equal 32 then you got it.  

Answer:

I believe that this is true. Anyone can do well in math, not everyone. The main difference being that if EVERYone could, that means every one person in the world, no matter the circumstance, so by saying ANYone, it's saying that however many people in the world want to do it, can do it, if they try and put in the work. Math is not biased against any one person, nor is it  favored for any one person. Any person who studies, or learns it can do well in math. Someone who has never learned anything about math will not do well at all. So, yes, ANYone can do well, but not EVERYone.

Answer:

$229.50

Step-by-step explanation:

Given;

The price of one pair of shorts is $45.00.

There is a 15% discount if you purchase four or more pairs

To FInd;

What is the total cost, before tax, for six pairs of shorts?

Solve:

Since one pair of shorts is $45

Then six pairs of shorts =

$45 x 6 = $270

Now it also says "There is a 15% discount if you purchase four or more pairs". So we buy six pairs thus, it more than four.

Hence,

$270 x 15% = 40.50

$270 - 40.50 = 229.50

Hence, Answer = $229.50

Step-by-step explanation:

Answer: 18,359.2 mL

Step-by-step explanation:

We know that the rain lasted for 4.2 hours.

Each hour, has 60 minutes.

Then the time of the rain was = 4.2*60min = 252 min.

Now, we know that the rate of the rain is 3 quarts per 39 minutes.

Then the total amount of rain, in quarts, will be:

R = (252min/39min)*3 quarts = 19.4 quarts.

But we want this answer in milliliters, then we can use the relation:

1 quart = 946.353 mL

Then 19.4 quarts are equal to: 19.4*(946.353 mL) = 18,359.2 mL

Answer: D. 14.1 cubic inches

Step-by-step explanation:

Formula for volume of a sphere: 4/3 x pi x radius cubed

Substitute: 4/3 x pi x 1.5 cubed

= 14.1

Answer:

14.13

Step-by-step explanation:

Sphere formula;

v = 4/3πr^3

Where pi is 3.14 or 22/7

R is the radius which is cubed

Substitute the radius(1.5) into the formula:

v = 4/3πr^3

v = 4/3 * 3.14 * 1.5^3

v = 4/3 * 3.14 * 3.375

v = 4/3 * 10.5975

v = 42.39/3

v = 14.13, our closest answer would be D.
