Answer:

41 and 205

Step-by-step explanation:

Since the smaller number is 1/5 the larger number, the distance between the numbers is 4/5 of the larger number because (5/5 - 1/5 = 4/5).

You are given the difference, so first find the smaller number by dividing by 4:

164 = (4/5)(larger number)

164 = 4(smaller number)

41 = smaller number

Now, just multiply by 5, since 41 is 1/5 of the larger number:

41 * 5 = 205 = larger number

Optionally, check the answer by testing the difference:

205 - 41 = 164

The values of x in the quadratic equation using completing the square method are [tex]x=-4 \pm \sqrt{5}[/tex].

Given information:

The quadratic equation is [tex]x^2+8x+11=0[/tex].

It is required to factorize the given quadratic equation using completing the square method.

Use completing the square method to solve the equation as,

[tex]x^2+8x+11=0\\(x)^2+2(x)(4)+4^2-4^2+11=0\\( (x)^2+2(x)(4)+4^2)-4^2+11=0\\(x+4)^2-16+11=0\\(x+4)^2=5\\(x+4)=\pm \sqrt{5} \\x=-4 \pm \sqrt{5}[/tex]

Therefore, the values of x in the quadratic equation using completing the square method are [tex]x=-4 \pm \sqrt{5}[/tex].

The revenue function is the sum of the cost and profit functions

The total amount of revenue on Sunday is $59.17

The function for the number of roses is given as:

[tex]N(d) = 6d + 25[/tex]

The price per rose is given as:

[tex]P(d) = 0.02d^2 - 0.04d + 0.49[/tex]

On Sunday, the value of d is 6.

So, we start by calculating N(6) and P(6)

[tex]N(d) = 6d + 25[/tex]

[tex]N(6)= 6 * 6 + 25[/tex]

[tex]N(6)= 61[/tex]

[tex]P(d) = 0.02d^2 - 0.04d + 0.49[/tex]

[tex]P(6) = 0.02 * 6^2 - 0.04 * 6 + 0.49[/tex]

[tex]P(6) = 0.97[/tex]

The total amount of revenue is then calculated as:

[tex]R(d) = N(d) * P(d)[/tex]

Substitute 6 for d

[tex]R(6) = N(6) * P(6)[/tex]

So, we have:

[tex]R(6) = 61 * 0.97[/tex]

[tex]R(6) = 59.17[/tex]

Hence, the total amount of revenue is $59.17

The measure of the reference angle = 30°

Step-by-step explanation:

Convert 11[tex]\pi[/tex]/6 (radians) to degrees by multiplying by 180 and dividing by [tex]\pi[/tex]:

11[tex]\pi[/tex]/6 (radians) = 330[tex]\pi[/tex]/[tex]\pi[/tex] = 330°

Therefore, reference angle = 360 - 330 = 30°

First convert to degree from radian .

This problem cannot satisfy the triangle inequality. The triangle cannot be constructed and therefore solved.  

a = 35

b = 2

c = 6

b+c ≤ a

2 + 6 ≤ 35

41 ≤ 35

The sum of the lengths of sides b, c must be greater than the length of the remaining side a.

Answer:

[tex]a=1.749[/tex]

Step-by-step explanation:

Recall Law of Sines

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

Solve for angle B

[tex]A^\circ+B^\circ+C^\circ=180^\circ\\35^\circ+B^\circ+6^\circ=180^\circ\\41^\circ+B^\circ=180^\circ\\B^\circ=139^\circ[/tex]

Determine side "a" given angle B and side "b"

[tex]\frac{sin(35)^\circ}{a}=\frac{sin(139^\circ)}{2}\\ asin(139^\circ)=2sin(35^\circ)\\a=\frac{2sin(35^\circ)}{sin(139^\circ)}\\ a\approx1.749[/tex]

When creating a confidence interval, higher confidence corresponds to a   larger   interval, and lower confidence corresponds to a   smaller   interval.

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

Explanation:

Imagine you are going fishing for an elusive sea creature of some kind. Casting a very wide net means we are more confident in catching the creature, in comparison to using a smaller net.

The fishing net is analogous to the width of the confidence interval. The wider the confidence interval, the more confident that we're capturing the parameter we're trying to measure.

Answer: $9.50

Step-by-step explanation:Let's define the variables:

A = price of one adult ticket.

S = price of one student ticket.

We know that:

"On the first day of ticket sales the school sold 1 adult ticket and 6 student tickets for a total of $69."

1*A + 6*S = $69

"The school took in $150 on the second day by selling 7 adult tickets and student tickets"

7*A + 7*S = $150

Then we have a system of equations:

A + 6*S = $69

7*A + 7*S = $150.

To solve this, we should start by isolating one variable in one of the equations, let's isolate A in the first equation:

A = $69 - 6*S

Now let's replace this in the other equation:

7*($69 - 6*S) + 7*S = $150

Now we can solve this for S.

$483 - 42*S + 7*S = $150

$483 - 35*S = $150

$483 - $150 = 35*S

$333 = 35*S

$333/35 = S

$9.51 = S

That we could round to $9.50

That is the price of one student ticket.

Hey there, hope you are having a wonderful day! :)

Let's solve this inequality.

First of all, let's move all the numbers to the right, using the [tex]\bf{\underline{opposite\:\:operation\:}[/tex]:

[tex]\longmapsto[/tex][tex]\sf{x-1\geq 4+x[/tex]

[tex]\longmapsto\sf{x\geq 4+x+1[/tex]

[tex]\longmapsto\sf{x\geq x+5[/tex]

Now, let's move the variables to the left:

[tex]\longmapsto\sf{x-x\geq 5[/tex]

[tex]\longmapsto\sf{0\geq 5[/tex]

Now, as you can see, we ended up with a false statement. 0 is NOT greater than 5.

Thus, there are no values of x that make the inequality true, and the inequality  has

The scale factor k for the sphere's volume in order to arrive at the volume of the new sphere is 3^3, the correct option is A

Suppose the initial measurement of a figure was x units.

And let the figure is scaled and new measurement is of y units.

Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.

Then we have:

[tex]s \times x = y\\s = \dfrac{y}{x}[/tex]

Thus, scale factor is the ratio of the new measurement to the old measurement.

Given;

Radius is multiplied by 3

In order to arrive at the volume of new sphere the factor must be greater or equal to 3

So,

Scale factor=x*k

=3^3

Therefore, the scale factor k will be 3^3
