Which of the following is NOT an irrational number?

Given:

Number of strawberry candy = [tex]\bold{8\ pieces}[/tex]

Number of rhubarb candy = [tex]\bold{7 \ pieces}[/tex]

Find the number of ways for equally distributing candy to all 5 children

Using formula:

[tex]\to \bold{_{n} C_{r}=\frac{n !}{r!(n-r) !}}[/tex]

Calculating the distributing way for strawberry candy:

[tex]\to \bold{_{8} C_{5}=\frac{8 !}{5!(8-5) !}}[/tex]

           [tex]\bold{=\frac{8 !}{5! \ 3 !}}\\\\\bold{=\frac{8 \times 7 \times 6 \times 5!}{5! \ 3 \times 2\times 1}}\\\\\bold{=\frac{8 \times 7 \times 6 }{ 6}}\\\\\bold{=8 \times 7}\\\\\bold{=56}[/tex]

Calculating the distributing way for rhubarb candy:

[tex]\to \bold{_{7} C_{5}=\frac{7 !}{5!(7-5) !}}[/tex]

           [tex]\bold{=\frac{7 !}{5! \ 2 !}}\\\\\bold{=\frac{7 \times 6 \times 5!}{5! \ 2\times 1}}\\\\\bold{=\frac{ 7 \times 6 }{ 2}}\\\\\bold{=7 \times 3}\\\\\bold{=21}[/tex]

Adding both distributing ways:

[tex]\to \bold{56+21=77}[/tex] ways

Answer:

[tex]T_7 = 136.6875[/tex]

Step-by-step explanation:

Given

12, 18, 27, ..

Required

Determine the 7th term

The above sequence shows a geometric sequence and the nth term is calculated by:

[tex]T_n = a * r^{n-1[/tex]

r is calculated by:

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{18}{12}[/tex]

[tex]r = 1.5[/tex]

[tex]a = 12[/tex] --- First term

[tex]n = 7[/tex]

So:

[tex]T_n = a * r^{n-1}[/tex]

[tex]T_7 = 12 * 1.5^{7-1[/tex]

[tex]T_7 = 12 * 1.5^6[/tex]

[tex]T_7 = 136.6875[/tex]

Answer:

angle 3 is 30 and 4 is 150 because total angle is 180 between 3 and 4

Answer:

from 3 o’clock until 3:20, the minute hand will move 1/3 of the way around the circle or 120 degrees. But the hour hand has also moved 1/3 of the way to the next number, or 10 degrees.

Answer:

42deg

Step-by-step explanation:

Let's see.

We'll consider 12:00 the "starting position"

The minute hand moves with the speed of 360deg in an hour, so 6deg per minute.

The hour hand moves with the speed of 360deg in 12hours, so 30deg per hour, so 0.5deg per minute.

at 3:24, the minute hand has moved 24*6deg=144deg from the starting position, while the hour hand has moved by 3*30deg + 24*0.5deg = 102deg

The absolute difference of the angles is 144deg-102deg = 42deg and it's the angle between the hands.

Answer:

[tex]\boxed{12u^3+8u^2-6u+9}[/tex]

Step-by-step explanation:

[tex](8u^3+8u^2+6)+(4u^3-6u+3) = 8u^3+8u^2+6+4u^3-6u+3[/tex]

Once

[tex]8x+4x = 12x, \text{ as } x = u^3[/tex]

[tex]8u^3+8u^2+6+4u^3-6u+3 = 12u^3+8u^2+6-6u+3 = \boxed{12u^3+8u^2-6u+9}[/tex]

Step-by-step explanation:

Insurance costs are influenced by any factor that can reasonably be tied to the cost of claims made against an insurance policy. These costs are carefully analyzed by insurance companies to determine correlations that may be influential.

__

In general, women have different driving habits than men, so gender has an influence on insurance costs.

Some areas of a city have different statistics related to vandalized or stolen vehicles, so may influence insurance costs. Certain areas may have different accident statistics, or may experience different kinds of accidents, so repair costs may differ by where you live or where you drive.

Some cars are more expensive to repair than others. Any car with custom features (stereo, upholstery, paint) will likely cost more to repair (and may be subject to more vandalism).

So, all of the above influence insurance costs.
