Answer:

c.  12/5

Step-by-step explanation:

With reference angle C

perpendicular (P)= 24

base(b) = 10

Then

Tan < C = p / b

Tan < C = 24/ 10

Tan < C = 12/5

Answer: 220 miles

Step-by-step explanation:

Let's write the equations for each case:

A Hertz Rent-a Car:

Charges a fixed amount of $40, plus a $0.10 per mile.

Then if you drive x miles, we get a total cost of:

C(x) = $40 + $0.10*x

Enterprise Rent-A-Car:

Chares a fixed amount of $18 plus $0.20 per mile, so if you drive x miles, the cost is:

K(x) = $18 + $0.20*x

Now, we want to find how many miles you can drive such that you would pay the same in both companies.

Then we need to find x such that:

C(x) = K(x)

$40 + $0.10*x = $18 + $0.20*x

Let's solve this for x.

$40 - $18 = $0.20*x - $0.10*x

$22 = ($0.20 - $0.10)*x

$22 = $0.10*x

$22/$0.10 = x

220 = x

So if you drive exactly 220 miles, you would pay the same in both companies.

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]

You don't need to factor.

Answer:

[tex]P(3) = 0.3397[/tex]

Step-by-step explanation:

The given details represent binomial distribution. So, we have:

[tex]n = 5[/tex]

[tex]p = 64\% = 0.64[/tex]

Required

Calculate P(3)

This is calculated using:

[tex]P(x) = ^nC_x * p^x * (1- p)^{n-x}[/tex]

This gives:

[tex]P(3) = ^5C_3 * 0.64^3 * (1- 0.64)^{5-3}[/tex]

[tex]P(3) = 10 * 0.64^3 * 0.36^2[/tex]

[tex]P(3) = 0.3397[/tex]

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

Step-by-step explanation:

Answer:

1.5 moles

Step-by-step explanation:

number of moles = no. of particles / Avagadro number

therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23

therefore, no. of moles = 1.5

There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

Answer:

He had 5 minutes left for question C.

Step-by-step explanation:

20 minutes to do the quiz.

He spent:

11 minutes on question A

4 minutes of question B.

So, for the first 2 questions, he used 15 minutes.

How much time did he have left for question C?

Total of 20 minutes, in the first two questions he used 15. So

20 - 15 = 5

He had 5 minutes left for question C.
