Write a factor that you can use to rationalize the denominator of √2/√5−8.

Answer: √5+8

Step-by-step explanation:

[tex] = ( - 4s + 9) + (4s - 6)[/tex]

[tex] = - 4s + 9 + 4s - 6[/tex]

[tex] = - 4s + 4s +9 - 6[/tex]

Since x, 2x, 3x contain numbers and variables, it takes two steps to find the LCM. Find the LCM for the numerical part 1; 2; 3; then find the LCM for the variable part x¹ ; x¹; x¹.

The LCM is the smallest number by which all numbers are divided without leaving a remainder.

The number 1 is not a prime number because it only has one positive factor, which is itself.

not cousin.

Since 2 has no divisors other than 1 and 2.

2 is a prime number.

Since 3 has no divisors other than 1 and 3.

3 is a prime number.

The least common multiple LCM of 1,2,3 is the result of multiplying all the prime factors the greatest number of times that appear in each term.

2 × 3

Multiply 2 by 3.

6

The factor for x¹ is x itself.

x¹ = x

The Least Common Multiple LCM of x¹ ; x¹; x¹ is the result of multiplying all the prime factors the greatest number of times that appear in each term.

x

The LCM for x;2x;3x is the numerical part 6 multiplied by the variable part.

======================================================

Explanation:

3/6 = 1/2 of the numbers on the cube are even (2,4,6)

If we wanted both cubes to show an even number, then this comes up (1/2)*(1/2) = 1/4 of the time.

There are 6*6 = 36 outcomes total, so there are (1/4)*36 = 9 outcomes when both dice show an even number.

---------

Those nine outcomes are listed below

You probably have noticed that A has 3 choices (2,4,6) and so does B. That gives 3*3 = 9 outcomes total. This is an alternative pathway compared to the previous section.

Box 2

Step-by-step explanation:

Box 1: 2x3x2=4x3=12

Box 2: 2x3x1=6x1=6

Box 3: 2x3x4=6x4=24

Using the relation between velocity, distance and time, it is found that the expression for the total time is given by:

[tex]t = \frac{9}{2x}[/tex]

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex].

Denise bikes 3 miles to her friend's house, hence:

[tex]v_1 = \frac{3}{t_1}[/tex]

[tex]t_1 = \frac{3}{v_1}[/tex]

The average rate biking to her friend's house is twice the average rate coming home, hence, on the return, [tex]v_2 = 0.5v_1[/tex]:

[tex]v_2 = \frac{3}{t_2}[/tex]

[tex]t_2 = \frac{3}{v_2}[/tex]

[tex]t_2 = \frac{3}{0.5v_1}[/tex]

[tex]t_2 = \frac{6}{v_1}[/tex]

The total time is given by, considering [tex]v_1 = 2v_2 = 2v = 2x[/tex], as we want to consider x the rate coming home:

[tex]t = t_1 + t_2[/tex]

[tex]t = \frac{3}{2x} + \frac{6}{2x}[/tex]

[tex]t = \frac{9}{2x}[/tex]

The number of people of the country which is predicted will be illiterate in the year 2025 are 1,300,700.

Percentage decrease is the amount deducted or reduced from the initial value in the percentage part.

In the year 2017, an estimated 4,347,000 people in this country are illiterate. With new incentives and funding, The country is hoping to cut that number by 14% every year.

Total year from 2017 to 2025 are 8 years. Thus, use the following formula of compound interest to find percentage decrease:

[tex]A=P\times\left(1+\dfrac{r}{100}\right)^{t}\\[/tex]

Here, A is the final population, The initial population is P, the rate is r and the time period is t. Put the values,

102₅ = 1×5² +0×5 +2×1

  = 27₁₀

Step-by-step explanation:

well, what do we expect in theory ?

a coin has a 50/50 chance for beads or tails. so, a probability of 1/2 for either one.

the probability for a survival number in a die is 1/6.

remember, the probability is always desired results over total possible results.

so, the combination is a simple multiplication.

the probability to get a certain side of the coin AND a certain number on the die is

1/2 × 1/6 = 1/12

so, this is what we would expect in theory : every combination happens in 1/12 of all cases.

now, what do we see in our practical experiment ?

there were 24 events (so, the total possible results are 24).

how many of them had heads and a 3 (the desired results) ?

there was only 1 result (in fact, there was only one 3 independently from the coin result, which is surprisingly low for 24 rolls of a die).

so, our experiment shows us a ratio or experimental probability of

1/24

for the desired result of heads with a 3 on the die.

we expected to get a ratio of

1/12 = 2/24

so, in reality, we got 1/24 less than theoretically expected.

We Know:-

[tex] \tan \theta = \frac{ \text{height of the tree}}{ \text{length of the base}} \\ \\ \implies \tan30 = \frac{ \text{x}}{25} \\ \\ \implies \text{x }= 25 \times \tan30 \\ \\ \implies \text{x }= 25 \times 0.577 \\ \\ \implies \text{x} = 14.425 \\ \\ \implies \text{x} = 14.43[/tex]

Option C is the correct answer

Answer:

Tom's class had the lower score

Step-by-step explanation:

Because the range is larger for Tom's class than it is for Brad's class, it is rather likely that students in Tom's class did not do as well on the test than students in Brad's class did.

The midline of the given graphed function for the y-coordinate is equal to y = 0.

The midline of a set of functions, you need to determine the average of their highest and lowest points.

For the functions represented in the graph,

y = 0.5.

The highest point is 0.5 for the graph.

y = -0.5

The lowest point is-0.5.

The midline of the set of functions is the average of their highest and lowest points.

Midline represented by a horizontal line.

Midline is the line that exactly passes through the midpoint of the highest and the lowest point.

Here on y-axis we have ,

Highest coordinate = 0.5

Lowest coordinate = -0.5

Midline point = ( highest point + lowest point ) / 2

Substitute the value we get,

⇒midline point = ( 0.5 + (-0.5))/ 2

⇒midline point = 0 /2

⇒midline point = 0

Therefore, the midline of the function of the graph is y = 0.

I can't give the exact answer as the base pay and weekly hours arn't stated but here's how to solve letters in parentheses are place holders just plug in the numbers accordingly :)

Step-by-step explanation:

A.

figures needed, base pay (p) total hours worked (t) half

Saturday

p÷2= the ½ in time and a half (x)

p+x= 1 hr Saturday pay (s)

s+2= r (to cover the 30m)

7:00am to 11:30am 4hr 30m

12:00pm to 4:00pm 4hr

add them

8hr 30m

(s×8)+r= how much you were paid on Saturday

Sunday

p×2= h dubble pay

Calculate how many hrs worked on Sunday and apply the same logic as for Saturday appropriately divide the time if it doesn't come out as an even hour.

Final

Add Saturday and Sunday pay together to get weekend pay.

Answer:

0.48.

Step-by-step explanation:

There are 2 ways that a tail lands once:-

Tail + head or

head + tail.

Prob(Tail on one throw) = 0.4

Prob(Head on one throw) = 1 - 0.4 = 0.6.

Prob(Tail first then head) = 0.4 * 0.6 = 0.24

Head then tail has the same probability (0.6*0.4).

So the requred probability = 0.24 + 0.24

= 0.48.
