WILL MARK BRAINLIEST ANSWER PLEASE HELP ASAP!!! Which of the following expressions can be used to rationalize the fraction below? 15/square root3

Answer:

[tex]1.6 \times 10^{-6}[/tex]

Step-by-step explanation:

[tex](8 \times 10^{-3}) \times (2 \times 10^{-4})[/tex]

[tex]8 \times 2 \times 10^{-3} \times 10^{-4}[/tex]

[tex]16 \times 10^{-3+(-4)}[/tex]

[tex]16 \times 10^{-3-4}[/tex]

[tex]16 \times 10^{-7}[/tex]

[tex]1.6 \times 10^{-6}[/tex]

Answer:

(8 × 10^-3)× ( 2× 10 ^-4)

reorder the terms

You will get

(8 × 2) ( 10^ -3 × 10^-4)

Multiply

16 ( 10^ -3 × 10^-4)

Use the rules of indices

a^ b × a^ c = a^b+c

16(10^-3-4)

16(10^-7)

= 16 × 10^-7 or 1.6 × 10^-6 or 0.0000016

Hope this helps.

Answer:

Option B, C and E are supplementary angles.

Step-by-step explanation:

We need to find supplementary angles.

Supplementary angles are those angles who sum up to 180 °.

I have attached picture for reference.

Looking at the figure given:

We have supplementary angles:

∠4 and ∠3

∠4 and ∠5

∠5 and ∠6

∠7 and ∠8

∠3 and ∠6

But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6

So, Option B, C and E are supplementary angles.

Supplementary angles are pair of adjacent angles that add up to 180 degrees

For a pair of angles to be supplementary, then the following must be true

The image is not given.

So, I provided a general explanation

Answer: [tex]\dfrac{1}{8}[/tex]

Step-by-step explanation:

Formula : Probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

Given , Sam has 4 cards numbered 2,3,5, and 7.

His friend has 4 cards numbered 1,2,6 and 7.

If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).

i.e. Number of possible outcomes would be (S) 4 x 4 = 16

Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)

Now , the probability that they will both choose the same number would be :

[tex]\dfrac{F}{S}=\dfrac{2}{16}=\dfrac{1}{8}[/tex]

Hence, the required probability = [tex]\dfrac{1}{8}[/tex]

The sequence is the Fibonacci sequence!

It works like this.

1+2=3

2+3=5

3+5=8

5+8=13

8+13=21

and so on.

Answer:

Step-by-step explanation:

Ad the last two for the next

(1+2)= 3.  3+5=8.......

so 13+21= 34

Answer:

Hope this helps..

Step-by-step explanation:  

So when you need to divide one complex number by another, you multiply the numerator and denominator of the problem by the conjugate of the denominator. This step creates a real number in the denominator of the answer, which allows you to write the answer in the standard form of a complex number.

Answer:

You have to multiply by the complex conjugate because the denominator has to be a real number. By multiplying the complex conjugate you can transform the denominator in to a real number.

Answer:

z = 3

Step-by-step explanation:

Using the rule of exponents

[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]

Thus

[tex](q^{4}) ^{z}[/tex] = [tex]q^{4z}[/tex] , so

[tex]q^{4z}[/tex] = [tex]q^{12}[/tex]

Since the bases on both sides are equal then equate the exponents

4z = 12 ( divide both sides by 4 )

z = 3

Answer:

The value of z is 3.

Step-by-step explanation:

You have to use Indices Law,

[tex] {( {a}^{m}) }^{n} \: ⇒ \: {a}^{mn} [/tex]

So for this question, first you have to get rid of brackets :

[tex] { ({q}^{4} )}^{z} = {q}^{12} [/tex]

[tex] {q}^{4z} = {q}^{12} [/tex]

Next you can solve it since both have the same bases :

[tex] {q}^{4z} = {q}^{12} [/tex]

[tex]4z = 12[/tex]

[tex]z = 3[/tex]

Answer:

{4, 9, 14, 19, 24}

Step-by-step explanation:

Best to use the notation a(1) = 4, a(n) = a(n-1) + 5.

a(1) = 4  (given)

a(2) = 9  (here we found a(2) by adding the common difference, 5, to a(1)

a(3) = 14

a(4) =  19

a(5) = 24

Height = 8cm

Step-by-step explanation:

I hope it helps

The required height of the cylinder is 8cm.

A  cylinder of base radius 4cm. The ratio of the area of it's base to that of it's curved surface area is 1:4. Height of cylinder is to be determine.

Surface area is defined as the area of the surface that are uncovered.

Here,
area of circle/surface area of cylinder=1/4
πr²/2πrh=1/4
r/2h=1/4
h=2r
where r = 4cm
h = 2*4
h = 8cm

Thus, the required height of the cylinder is 8cm.

Answer:

On average, Albani gets 20.933 inches of rain per year.

On average, Zachary gets 24.734 inches of rain per year.

On average, Zachary gets more rain than Albani.

Step-by-step explanation:

Mean is given by:

[tex]Mean = \frac{Sum}{Total}[/tex]

For Albani :

Sum of total number of terms = 23.36+18.51+28.54+22.36+30.50+24.74+11.93+15.34+18.07+15.98

Sum of total number of terms = 209.33

Number of terms = 10

[tex]Mean=\frac{209.33}{10}\\\\Mean=20.933\\[/tex]

For Zachary :

Sum of total number of terms = 27.27+20.11+31.14+25.88+32.97+25.03+18.55+23.91+22.75+19.73

Sum of total number of terms = 247.34
