Answer:

1. [tex]-5-\sqrt{x}[/tex]

2. [tex]7+\sqrt{b}[/tex]

Step-by-step explanation:

The conjugate of a radical expression

[tex]a+\sqrt{b}[/tex]

is the expression

[tex]a-\sqrt{b}[/tex]

And vice-versa.

The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.

The question asks to find the conjugate of:

1. [tex]-5+\sqrt{x}[/tex]

The conjugate is

[tex]-5-\sqrt{x}[/tex]

2. [tex]7-\sqrt{b}[/tex]

The conjugate is

[tex]7+\sqrt{b}[/tex]

Answer:

A unit rate is a special kind of ratio, where the second number, or the denominator, is equal to one. With a unit rate, you are comparing a quantity to one. Some common unit rates are miles per gallon, price per pound, and pay rate per hour. ... Next, divide the price by the pounds so you can find the unit rate.

Answer:

h= 2v / πr²

Step-by-step explanation:

height of a cone is twice of it's volume divided by π and square of radius

Step-by-step explanation:

v = 1/2 πr²h

v / 1/2 πr² = 1/2 πr²h / 1/2 πr² (Divide both sides of the equation by 1/2 πr² to find the formula for height (h).

v / 1/2 πr² = h or h = 2v / πr²

Answer:

c. 500 + 24 * 8

Step-by-step explanation:

if there is 500 gallons of water already in the swimming pool and we are trying to add more and we are adding 24 gallons for 8 minutes to the already existing pool of water.

The expression 500 + 24 × 8 represents the amount of water in the pool, in gallons, after 8 minutes. The correct answer would be an option (C).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

If the swimming pool currently has 500 gallons of water in it and we are trying to add more, we would add 24 gallons of water over the course of 8 minutes.

As per the given information, the required expression would be as

500 + 24 × 8

Thus, the expression 500 + 24 × 8 represents the amount of water in the pool, in gallons, after 8 minutes.

Hence, the correct answer would be option (C).

Total cost             7875        5225           9000   22100

Step-by-step explanation:

1                                  $12    $13     $10

Answer:

4[tex]\sqrt{13}[/tex]

4[tex]\sqrt{13}[/tex] + 8

4[tex]\sqrt{13}[/tex] + 16

Step-by-step explanation:

as per the given information:

shorter leg = x

longer leg = x + 8

hypotonuse = x + 8 + 8

remember the Pythagorean theorem, which states

x^2 + y^2 = n^2

where x and y are the legs and n is the hypotenuse

so now one can set up an equation:

x^2 + ( x + 8 )^2 = ( x + 16 ) ^2

simplify and solve using inverse operations:

first preform the square

x^2 + x^2 + 16x + 64 = x^2 + 32x + 256

then preform inverse opertations and simplify

2x^2 + 16x + 64 = x^2 + 32x + 256

-x^2                       -x^2

x^2 + 16x + 64 = 32x + 256

       -16x            -16x

x^2 + 64 = 16x + 256

       - 64             -64

x^2 = 16x + 192

-16x     -16x

x^2 - 16 = 192

x^2 -4^2 = 192

remember the differnt ways of writing a special square

(x - 4) (x + 4) = 192

x = 4[tex]\sqrt{13}[/tex]

now add 8 to find the longer leg

4[tex]\sqrt{13}[/tex] + 8

an add another 8 to find the hypotenuse

4[tex]\sqrt{13}[/tex] + 8 + 8

4[tex]\sqrt{13}[/tex] + 16

Answer:

No integers are irrational.

Step-by-step explanation:

Think about the real number system, whole numbers contain natural numbers, integers contain whole numbers, rational numbers contain integers, and real numbers contain all of these including irrational numbers. An irrational number is separate from the rest of the real numbers because it cannot be expressed or written as a fraction or decimal.

Answer:

both

Step-by-step explanation:

hi! let's plug in the ordered pairs into the equation. the x-coordinate is substituted for x in the equation, while the y-coordinate is substituted for y.

y≥-2x+4

(0,4)

4≥-2(0)+4

4≥0+4

4≥4

this is correct since 4 is equal to 4.

(-1,8)

8≥-2(-1)+4

8≥2+4

8≥6

this is also correct since 6 is less than 8.

therefore, both ordered pairs are solutions of the inequality.

After 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
To find the total cost of the songs,
= 12 songs × $0.80/song = $9.60

Then, the total cost of the subscription and the songs over 6 months:
= $9.99 + (6 × $9.60)
= $9.99 + $57.60
= $67.59.

So, after 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

Step-by-step explanation:

2/3 ÷ 4

¨We use copy dot flip

The flip means make a reciprocal of the second number

2/3 * 1/4

Multiply the numerators

2*1 = 2

Multiply the denominators

3*4 =12

Put the numerator over the denominator

2/12

Simplify

1/6¨

Answer:

1/6

Step-by-step explanation:

You find a fraction that is equal 2/3 and has a multiple of 4 for the numerator. Then you have to multiply the numerator and the denominator by 2 then you get 4/6 divided by 4, since 2/3 is equal to 4/6. So the answer is 1/6.

Answer:

0.0452

Step-by-step explanation:

Given that:

There are a total of 193 males in the sample.

Number of males who smoke = 27

There are a total of 169 females in the sample.

Number of females who smoke = 16

The ratio of people who smoke to the total number of people is given by the formula:

[tex]\dfrac{\text{Number of people who smoke}}{\text{Total number of people in the sample}}[/tex]

So, the ratio of males who smoke is given as:

[tex]\dfrac{27}{193}=0.1399[/tex]

And

The ratio of females who smoke is given as:

[tex]\dfrac{16}{169} = 0.0947[/tex]

The difference between the ratio is = 0.1399 - 0.0947 = 0.0452

Answer:

y = x/4

Step-by-step explanation:

First, replace f(x) with y, so it's easier to find the inverse:

y = 4x

To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:

x = 4y

y = x/4

Therefore, the inverse function of y = 4x is y = x/4.

Answer:

27/50

Step-by-step explanation:

Just do 9/10/3/5

Answer:If the question is asking for 9/10/3/5 the answer is 3/50; however, if the question is asking for (9/10) / (3/5), the answer should be 3/2.

Step-by-step explanation: The 3/50 answer comes from 9/10 which equals .9, dividing that by 3. That equates to .3, and then dividing by 5 which measures up to .06. From there you can turn .06 into a fraction being 3/50.

You get the 3/2 by dividing (9/10) by (3/5). .9/.6 is 1.5. When converted to a fraction 1.5=3/2. Hope this could help.
