Answer:

hello

5 x - 1

inverse  = 1 / ( 5 x- 1 )

Step-by-step explanation:

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.

The sum of all the angles of a triangle is 180 degrees

We see that Line HI and JI are equal in length meaning that triangle HIJ is an isosceles triangle. This means that the two angles of unknown measure are both x.

So lets now set up our equation:

  [tex]x + x + 74 = 180\\2x = 106\\x = 53[/tex]

Thus x is 53 degrees

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:

A) 0.65 · 20

D) [tex]\mathsf{\dfrac{65}{100} \cdot 20}[/tex]

Step-by-step explanation:

To find 65% of 20:

Method 1

65% in decimal form is:  65% = 65/100 = 0.65

Therefore, to find a percentage of a number, multiply the percentage in decimal form by the number:

[tex]\mathsf{\implies 65\% \ of \ 20 = 0.65 \cdot 20}[/tex]

Method 2

Divide the number by 100 to get 1%, then multiply this by 20 to get 20%.

[tex]\mathsf{\implies \dfrac{65}{100} \cdot 20}[/tex]

~The word "of" stands for multiplication.~

Option A) 0.65 × 20

~0.65 can be converted to fraction, which is 65/100.~

~This expression correctly matches with the resulting expression.~

Thus, option A is correct.

Option B) 65/100 ÷ 20

This could've been equivalent to the resulting expression. However, the expression has a division sign.

Thus, Option B is incorrect.

Option C) 65/20 × 100

~To avoid confusion, let's further solve the expression.~

~Now, let's solve the resulting expression.~

~Since 13 does not equal 325, "65/20 × 100" does not equal "65/100 × 20".~

Thus, option C is incorrect.

Option D) 65/100 × 20

~This equation is the resulting equation.~

Thus, option D is correct.

Option E) 65 × 20

~To avoid confusion, let's further solve the expression.~

~Now, let's solve the resulting expression.~

Since 1300 does not equal 13, 65 × 20 does not equal 65/100 × 20.

Thus, option E is incorrect.

Option A and D were equivalent to 65/100 × 20.

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.

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].
