Hope this helps!! :)

Answer:

254.34cm²

Step-by-step explanation:

In order to find the area of a circle, you use the formula

[tex]A=\pi[/tex]×[tex]r^{2}[/tex], which is [tex]A=\pi (9)^{2}[/tex] if put into this problem.

You look for [tex]9^{2}[/tex] which equals 81. Then you plug it in to multiply to [tex]\pi[/tex]. Which is:

[tex]A=81\pi[/tex]

[tex]A= 254.34[/tex]

Answer: just an extra one foot

Step-by-step explanation:

Given that the length of the piece of string = 25,000 miles

 Since the string is long enough to exactly circle the globe at the equator over oceans, deserts and jungles. We can say that the string could completely circle a sphere

Assuming that the earth is a perfect sphere.

The circumference of the circle = 25,000 mile.

But note that the circumference of a circle is directly proportional to the radius. If you double the radius, the circumference will also be doubled. Half the circumference, half the radius. Increase the circumference by 30%, radius will also be increased by 30% and so on.

In this question, the radius is being increased by 3 feet, so we need to know that as a fraction of the original radius.

Circumference = 2πr

Let's also convert miles to feet

25000 × 5280 = 2(3.143)r

r = 132 × 10^6/2π

r = 21008452.5 feet

3 feet - that's how far off the ground we're lifting the string out of 21008452.5 feet is close to one part in 25000 miles. The string was 132000000 feet long to start with, so we need just an extra 1 foot.

Answer:

R=3.897

Step-by-step explanation:

Given the magnitude measured by the Ritcher scale is given as;

R = 0.67log(0.37E) + 1.46  where E= is the energy (in kilowatt hours)

If E=1,770,000 then

R= 0.67log(0.37*1770000)

R=0.67log(654900)

R=0.67*5.81617

R=3.897

Final answer:

To determine the magnitude of an earthquake that released 1,770,000 kilowatt hours of energy using the Richter scale formula, the calculated magnitude is approximately 5.51.

Explanation:

The Richter scale is used for measuring the magnitude of an earthquake. Given the Richter magnitude formula

R = 0.67log(0.37E) + 1.46

where E is the energy (in kilowatt hours) released by the earthquake, we can calculate the magnitude of an earthquake that released 1,770,000 kilowatt hours of energy.

First, substitute the given energy value into the formula:

R = 0.67log(0.37*1770000) + 1.46.

Performing the calculation:

0.37 * 1,770,000 = 654,900

log(654,900) = 5.816

R = 0.67 * 5.816 + 1.46

R ≈ 5.51

Therefore, the earthquake's magnitude on the Richter scale is approximately 5.51.

The plumber able to cut the 5-meter long pipe into 50 sections, each measuring 10 centimeters.

To find the number of sections the plumber  able to cut from a 5-meter long pipe, to convert the length to centimeters.

That 1 meter is equal to 100 centimeters. So, to convert 5 meters to centimeters, multiply 5 by 100:

5 meters × 100 centimeters/meter = 500 centimeters

Now that the length of the pipe in centimeters (500 cm), divide it by the desired length of each section, which is 10 centimeters:

500 centimeters / 10 centimeters/section = 50 sections

Step-by-step explanation:

From factoring rules for the difference of squares, it is possible rewrite the equation [tex]16x^4-81[/tex] as (2x-3)(2x+3(4x²+9).

In math, the factoring or factorization is used to write an algebraic expression in factors.

The question gives a polynomial and asks your respective factorization. Note that [tex]16x^4-81[/tex] is a difference of squares. The factoring rules shows that the difference of squares: a² – b² = (a – b)(a + b).

If [tex]16x^4-81[/tex] is a difference of squares. You can rewrite this expression as:

[tex]16x^4-81=(4x^2-9)(4x^2+9)[/tex].

Again, you have another difference of squares: 4x²-9. You can rewrite this expression as: 4x²-9= (2x+3)(2x-3).

Hence, [tex]16x^4-81=(2x-3)(2x+3)(4x+9)[/tex].

Final answer:

The expression 16x^4 − 81 is a difference of squares and can be factored completely into (2x + 3)(2x − 3)(4x^2 + 9).

Explanation:

The student has asked to factor the expression 16x4 − 81 completely. This expression is a difference of squares, where 16x4 is the square of 4x2, and 81 is the square of 9. According to the difference of squares formula, a2 − b2 can be factored into (a + b)(a - b). Therefore, 16x4 − 81 can be factored as:

(4x2 + 9)(4x2 − 9)

Next, observe that 4x2 − 9 is another difference of squares, which can be further factored into (2x + 3)(2x − 3). Combining these factors, we get the completely factored expression:

(2x + 3)(2x − 3)(4x2 + 9)

Answer:

x=3 one solution

Step-by-step explanation:

Let's solve your equation step-by-step.

−6x+19=x−2

Step 1: Subtract x from both sides.

−6x+19−x=x−2−x

−7x+19=−2

Step 2: Subtract 19 from both sides.

−7x+19−19=−2−19

−7x=−21

Step 3: Divide both sides by -7.

−7x /−7  =  −21 /−7

x=3

Answer:

x = 3

Step-by-step explanation:

Solve -6x + 19 = x-2

Solve for x:

19 - 6 x = x - 2

Subtract x from both sides:

19 + (-6 x - x) = (x - x) - 2

-6 x - x = -7 x:

-7 x + 19 = (x - x) - 2

x - x = 0:

19 - 7 x = -2

Subtract 19 from both sides:

(19 - 19) - 7 x = -19 - 2

19 - 19 = 0:

-7 x = -19 - 2

-19 - 2 = -21:

-7 x = -21

Divide both sides of -7 x = -21 by -7:

(-7 x)/(-7) = (-21)/(-7)

(-7)/(-7) = 1:

x = (-21)/(-7)

The gcd of -21 and -7 is -7, so (-21)/(-7) = (-7×3)/(-7×1) = (-7)/(-7)×3 = 3:

Answer: x = 3

Answer:

1284 Eggs

Step-by-step explanation:

To work this out you would first have to know how many days there are in a year, which is 365. Then you would need to add the amount of days in January and February. January has 31 days and February would have 29, and so 29 plus 31 is 60. Then you would add 60 to 365, which is 425. Then you would add 3 to 425, which is 428. Then you would divide 428 by 4, which is 107. Then you would multiply 107 by 12, which is 1284.

1) Find out how many days there are in a year.

There are 365 days in a year

2) Add 31 to 29.

[tex]31+29=60[/tex]

3) Add 60 to 365.

[tex]365+60=425[/tex]

4) Add 3 to 425.

[tex]425+3=428[/tex]

5) Divide 428 by 4.

[tex]428/4=107[/tex]

6) Multiply 107 by 12.

[tex]107*12=1284[/tex]

Answer: It takes Him 1/4 hours to decorate both signs,

Step-by-step explanation:

Hi, since the area of a rectangle is equal to:

Area: length x width

Replacing with the values given;

Sign 1 =A1 = 2/3 x 1/4 =1/6 ft2

Sign 2 =A2= 1/2 x 1/3 = 1/6 ft2

If we sum both areas:

A1 +A2 = 1/6 + 1/6 = 2/6 ft2 = 1/3 ft2 (total area)

Since it takes Roberto 3/4 hour to decorate a 1-square-foot sign:

For 1/3 ft2

3/4 hour x 1/3 ft2 = 1/4 h

ITt takes Him 1/4 hours to decorate both signs,

It takes Roberto 1/4 hour to decorate both signs.

To find the total amount of time it takes Roberto to decorate both signs, we need to calculate the area of each sign first and then determine the time required for each based on the given rate of 3/4 hour per 1 square foot.

1: Calculate the area of each sign

2: Calculate the total area of both signs

Total area (Atotal) = A1 + A2 = 1/6 + 1/6 = 2/6 = 1/3 square foot.

3: Calculate the total time to decorate both signs

It takes Roberto 3/4 hour to decorate 1 square foot. So, for 1/3 square foot:
Time = (3/4) × (1/3) = 1/4 hour.

Therefore, it takes Roberto 1/4 hour to decorate both signs.

23) a) n - (n+1)

Remove the parenthesis by multiplying (n+1) by (-1)

n - (n+1) = n - n - 1 = -1

b) n(n+1) = n*n + n*1

              = n² + n

c) When we are adding the two numbers it is,

n² + n - 1. This will always be odd because n² + n will always be even and when we subtract 1 from that it will be odd

Example: Take n = 3

n² + n =  3*3 + 3 = 9 + 3 =12; So, n² + n -1 = 12- 1 =11 --> odd

When n = 7

n² + n = 49 + 7 = 56 ; So, n² + n -1 = 56-1 = 55 ---> odd

When n =8

n² + n = 64 + 8 = 72;  So, n² + n -1 = 72 -1 = 71

When n = 16

n² + n = 256 +16 = 272 ; So, n² + n - 1 = 272 - 1 = 271 ----->odd

Answer: early redemption fee

Step-by-step explanation:

The type of fee charged for withdrawing money from a CD before the date of maturation is Early redemption fee.

We have to determine the type of fee charged for withdrawing money from a CD before the date of maturation.

We have given

A. FDIC fee

It required the largest taxpayer bailout in the year 2008 financial crisis, explained in a footnote on its schedule of fees for business accounts in the nation's  states that it charges an FDIC insurance fee at the annual rate of 13 cents per $100.

It related to insurance so it is not correct option.

B. Early redemption fee

The fee  may be required to make to a lender if we pay off a loan or mortgage before the scheduled term of the credit facility.

So the Banks and credit unions often charge a fee if you withdraw money before maturity.

Therefore the Option B is correct.

C. Liquidity fee

This is nothing but the  liquidity facility providers that the borrower may from time to time agree to pay.

Therefore this is not correct option
