Answer:

33%

Step-by-step explanation:

The area of the entire circle:

The radius is 4+3+3 = 10

Area of a circle= pi * r^2

Area of largest circle      = pi * 10^2 = 100 pi

Area of blue ring = Area of blue circle - area of inner white circle

The blue circle has a radius of (4+3) = 7

The inner white circle had a radius of 4

Substituting what we know

Area of blue ring = Area of blue circle - area of inner white circle

                               = pi * r^2 - pi*r^2

                               = pi * 7^2 - pi *4^2

                                = 49pi - 16pi

                                = 33 pi

The percentage of the logo that is blue is the blue ring/ area of largest circle

percentage = 33 pi/100 pi

Canceling pi

percentage = 33/100

                    = 33 %

Answer:

The common benefits of getting a full-time job are:

Remember that a full-time job has to have 40 hours per week. So, to compensate this amount of time spent in the company, they tend to "protect" their employees with better health insurance, their Social Security will give credits, which apply to retirement, and in case of accidents, their insurance will cover all costs.

All these variables make these jobs attractive in order to make people work even more.

Final answer:

The height of the new cones will be 16.5 inches.

Explanation:

To find the height of the new cones, we can use the formula for the volume of a cone:

V = (1/3)πr^2h

Let's denote the radius of the new cones as r2 and the height of the new cones as h2. We know that the volume of the new cones will be the same as the volume of the existing cones:

(1/3)π(r2)^2h2 = (1/3)π(r1)^2h1

Substituting the given values, r1 = 22 inches (radius of existing cones) and h1 = 66 inches (height of existing cones), we can solve for h2:

(1/3)π(44)^2h2 = (1/3)π(22)^2(66)

Dividing both sides by (1/3)π(44)^2, we get:

h2 = h1(r1/r2)^2

Plugging in the values, h1 = 66 inches and r1 = 22 inches, and r2 = 44 inches, we can calculate:

h2 = 66(22/44)^2

h2 = 66(1/2)^2

h2 = 66(1/4)

h2 = 66/4

h2 = 16.5 inches

We can write the argument of the logarithm as a power of 6:

[tex]\log_6\dfrac1{36}=\log_6\dfrac1{6^2}=\log_66^{-2}[/tex]

Then using the property that [tex]\log_ba^n=n\log_ba[/tex], we get

[tex]\log_6\dfrac1{36}=-2\log_66[/tex]

and since [tex]6=6^1[/tex], we have [tex]\log_66=1[/tex], so the value of this expression is simply -2.

The value of [tex]\(\log_6 \left(\frac{1}{36}\right)\)[/tex] is -2.
To evaluate [tex]\(\log_6 \left(\frac{1}{36}\right)\)[/tex], we can use properties of logarithms and exponents.

Let's set up the equation:

[tex]\[\log_6 \left(\frac{1}{36}\right) = x\][/tex]

This equation means:

[tex]\[6^x = \frac{1}{36}\][/tex]

We know that [tex]\(\frac{1}{36}\)[/tex] can be rewritten as [tex]\(6^{-2}\)[/tex] because:

[tex]\[36 = 6^2 \quad \text{so} \quad \frac{1}{36} = 6^{-2}\][/tex]

Thus, the equation [tex]\(6^x = \frac{1}{36}\)[/tex] becomes:

[tex]\[6^x = 6^{-2}\][/tex]

Since the bases are the same, we can equate the exponents:

x = -2

Therefore,

[tex]\[\log_6 \left(\frac{1}{36}\right) = -2\][/tex]

Answer:  The next term in the sequence is 5.

Step-by-step explanation:  We are given to find the next term in the following sequence :

1.31,   2.54,   3.77,   .   .   .  .

We can see the following pattern in the consecutive terms of the given sequence :

[tex]2.54=1.31+1.23,\\\\3.77=2.54+1.23,\\\\\\\vdots~~~~~\vdots~~~~\vdots[/tex]

Therefore, the next term in the given sequence will be the last given term plus 1.23.

That is, the next term will be

[tex]3.77+1.23=5.00.[/tex]

Thus, the next term in the sequence is 5.

Answer:

a. [tex]y=830*(0.87)^x[/tex]

b. The value of stereo system after 2 years will be $628.23.

c. After approximately 4.98 years the stereo will be worth half the original value.

Step-by-step explanation:

Let x be the number of years.

We have been given that you purchased a stereo system for $830. The value of the stereo system decreases 13% each year.

a. Since we know that an exponential function is in form: [tex]y=a*b^x[/tex], where,

a = Initial value,

b = For decay b is in form (1-r), where r is rate in decimal form.

Let us convert our given rate in decimal form.

[tex]13\%=\frac{13}{100}=0.13[/tex]

Upon substituting our given values in exponential decay function we will get

[tex]y=830*(1-0.13)^x[/tex]

[tex]y=830*(0.87)^x[/tex]

Therefore, the exponential model [tex]y=830*(0.87)^x[/tex] represents the value of the stereo system in terms of the number of years since the purchase.

b. To find the value of stereo system after 2 years we will substitute x=2 in our model.

[tex]y=830*(0.87)^2[/tex]

[tex]y=830*0.7569[/tex]

[tex]y=628.227\approx 628.23[/tex]

Therefore, the value of stereo system after 2 years will be $628.23.

c. The half of the original price will be [tex]\frac{830}{2}=415[/tex].

Let us substitute y=415 in our model to find the time it will take the stereo to be worth half the original value.

[tex]415=830*(0.87)^x[/tex]

Upon dividing both sides of our equation by 830 we will get,

[tex]\frac{415}{830}=\frac{830*(0.87)^x}{830}[/tex]

[tex]0.5=0.87^x[/tex]

Let us take natural log of both sides of our equation.

[tex]ln(0.5)=ln(0.87^x)[/tex]

Using natural log property [tex]ln(a^b)=b*ln(a)[/tex] we will get,

[tex]ln(0.5)=x*ln(0.87)[/tex]

[tex]\frac{ln(0.5)}{ln(0.87)}=\frac{x*ln(0.87)}{ln(0.87)}[/tex]

[tex]\frac{ln(0.5)}{ln(0.87)}=x[/tex]

[tex]\frac{-0.6931471805599}{-0.139262067}=x[/tex]

[tex]x=4.977286\approx 4.98[/tex]

Therefore, after approximately 4.98 years the stereo will be worth half the original value.

To find when a stereo system purchased for $830 and depreciating at 13% per year will be worth half of its value, use the exponential decay formula V(t) = [tex]P * (1 - r)^t[/tex]. After 2 years, the stereo is worth approximately $627.77, and it will be worth half its original value after about 5.42 years.

An exponential decay model can represent the value of an asset decreasing over time. For a stereo system purchased for $830 with a yearly depreciation of 13%, the model takes on the form of V(t) = [tex]P * (1 - r)^t[/tex], where:

V(t) is the value of the stereo system after t years.

P is the initial purchase price, which is $830.

r is the rate of decay per year, which is 13% or 0.13.

t is the number of years since the purchase.

The value of the stereo system after 2 years can be calculated using the above model:
[tex]V(2) = 830 * (1 - 0.13)^2 = 830 * 0.87^2[/tex]
= 830 * 0.7569
= $627.77 approximately.

To find when the stereo will be worth half the original value, we set [tex]V(t) = rac{P}{2}[/tex] and solve for t:

415 = [tex]830 * (1 - 0.13)^t[/tex]
[tex]0.5 = (1 - 0.13)^t[/tex]
[tex]Log_0.87(0.5) = t[/tex]
t
t = 5.42

The stereo will be worth half its original value after approximately 5.42 years.

56 is less than four times a number representing the inequality 56 < 4x thus option (D) is correct.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given inequality,

56 < 4x

Bryan's next step should look like: [tex]\[37.3 - 5.2\][/tex].

To evaluate the given expression, Bryan should follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).

Start with what's inside the parentheses:

[tex]\(42 / 3.2 = 13.125\)[/tex], and [tex]\(10(0.2) = 2\)[/tex]. So, inside the parentheses, we have: [tex]\(16 - 2 + 3 = 17\)[/tex].

Multiply and divide from left to right:

[tex]\(2.5 \times 17 = 42.5\).[/tex]

Substitute back into the expression:

[tex]\(42.5 - 5.2\).[/tex]

Complete the subtraction:

[tex]\(42.5 - 5.2 = 37.3\).[/tex]

Therefore, Bryan's next step should look like:

[tex]\[37.3 - 5.2\][/tex]

After this step, Bryan would perform the subtraction to find the final result. Following PEMDAS ensures that each operation is carried out correctly, leading to the accurate evaluation of the expression.

The distance between Seattle, WA, and San Francisco, CA, calculated using their latitudinal difference on a sphere with a radius of 4000 miles, is approximately 628 miles.

The question is asking for the distance between Seattle, WA and San Francisco, CA based on their respective latitudes and assuming they are on the same longitudinal line. To find the arc length and thus the distance between the two cities, you can use the formula for arc length on a sphere: [tex]\(Arc \ length = (\Delta Latitude \times \pi/180) \times \ Radius \ of\ Earth\)[/tex]. Here, [tex](\Delta Latitude\)[/tex] is the difference in latitude between the cities, which is [tex]\(47^\circ - 38^\circ = 9^\circ\)[/tex]. The radius of Earth is given as 4000 miles. Plugging these values into the formula, you get:

[tex]\(Arc \ length = (9 \times \pi/180) \times 4000\)[/tex]

[tex]\(Arc \ length = (9 \times 3.14/180) \times 4000\)\\\(Arc \ length = (0.157) \times 4000\)\\\(Arc \ length = 628 \ miles\)[/tex]

Therefore, the distance between Seattle and San Francisco, based on latitude and assuming they are directly north and south of each other, is approximately 628 miles.

Value of [tex]S_{22} = 15.4[/tex]

Step-by-step explanation:

Given: [tex]a_{12} = 2.4[/tex] and common difference(d) = 3.4

A sequence of numbers is arithmetic i.e,  it increases or decreases by a constant amount each term.

The sum of the nth term of a arithmetic sequence is given by;

[tex]S_n =\frac{n}{2}(2a+(n-1)d)[/tex], where n is the number of terms, a is the first term and d is the common difference.

We also know the nth tern sequence formula which is given by ;

[tex]a_n = a+(n-1)d[/tex]                             ......[2]

First find a.

it is given that [tex]a_{12} = 2.4[/tex]

Put n =12 and d=3.4 in equation [2] we have;

[tex]a_{12} = a+(12-1)(3.4)[/tex]

[tex]a_{12} = a+(11)(3.4)[/tex]

2.4 = a + 37.4

Simplify:

a = - 35

Now, to calculate [tex]S_{22}[/tex]

we use equation [1];

here, n =2 , a =-35 and d=3.4

[tex]S_{22} = \frac{22}{2}(2(-35)+(22-1)(3.4))[/tex]

[tex]S_{22} = (11)(-70+21(3.4))[/tex]

[tex]S_{22} = (11)(-70+71.4)[/tex]

[tex]S_{22} = (11)(1.4)[/tex]

Simplify:

[tex]S_{22} = 15.4[/tex]

Therefore, the sum of sequence of 22nd term i.e, [tex]S_{22} = 15.4[/tex]
