If in the survey of a survey of a community, 55%. The percentage of the people who don't like to listen to the radio as well as watch the television​ is 15%.

The number of people who like to listen to the radio as well as watch the television = 35%.

So,

The number of people who like to listen to the radio but don't like to watch the television

=  55% - 35%

= 20%

The number of people who like to watch television but don't like to listen to the radio =  65% - 35% = 30%.

The percentage of people who don't like to listen to the radio as well as watch the television

= 100% - (35% + 20% + 30%)

= 100% - 85%

= 15%

Therefore  15% of the people in the community don't like to listen to the radio or watch the television.

30 hot dogs would contribute $60 to the GDP and 20 hamburgers would also contribute $60 to the GDP.

The calculation for the number of hamburgers that would contribute the same to the GDP as 30 hot dogs is as follows:

GDP (Hot Dogs) = 2 x 30 = 60

GDP (Hamburgers) = 3 x x = 60  

Therefore, the number of hamburgers needed to equal the GDP of 30 hot dogs is equal to 20:

GDP (Hamburgers) = 3 x 20 = 60

Therefore, the answer is C) 20.

To explain this in more detail, Gross Domestic Product (GDP) is a measure of the total value of all goods and services produced in a country during a specific period of time. It is calculated by multiplying the price of a good or service by the amount produced. In this case, the price of a hot dog is $2 and the price of a hamburger is $3. Therefore, 30 hot dogs would contribute $60 to the GDP and 20 hamburgers would also contribute $60 to the GDP.

The par coupon rate of four-year, default-free security with annual coupon payments is 112%.

The par coupon rate of a four-year, default-free security with annual coupon payments can be calculated by taking the present value of all future coupon payments, plus the face value of the security, and dividing that amount by the face value of the security.

Par Coupon Rate = (Present Value of Coupon Payments + Face Value) / Face Value

Annual interest payment = [tex]\frac{12}{100} *1000[/tex]

Annual interest payment = $120

A face value of $1,000 and the present value of all future coupon payments is $120, the par coupon rate for this security would be 112%.

Par Coupon Rate = ($120 + $1,000) / $1,000

Par Coupon Rate = 1120 / 1000

Par Coupon Rate = $1.12

Par Coupon Rate = 112/100

Par Coupon Rate = 112 %.

The percentage decrease is 19.4%

In contrast to being expressed as a fraction, a percentage is a portion of a total expressed as a number between 0 and 100. The percentages are as follows: 100% of everything, 0% of nothing, 50% of something, and 0% of nothing. Divide the component by the total, then multiply the result by 100 to get the percentage.

(Original Cost - New Cost) / Original Cost x 100 equals the percentage decrease.

In this case, the original cost is $36 and the new cost is $29, so we plug these values into the formula:

Percentage decrease = ($36 - $29) / $36 x 100 = $7 / $36 x 100 = 0.1944 x 100 = 19.44%

We can round the answer to the nearest tenth of a percent:

The area of rhombus KLMN is 287.3 in²

A rhombus is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.

Given that, a rhombus KLMN with diagonals KM and NL,

Since, the diagonals of a rhombus bisects each other at a right angle,

Let they bisect at O, so, KM = 2MO = 2KO = 2×11.4 = 22.8 in

Therefore, Δ KON is a right triangle,

The tire will need to rotate 38.2 times to travel the whole length of the street.

We will first compute the tire's circumference in order to determine how many times it will need to revolve while traveling the distance of the roadway.

The formula for determining a circle's circumference may be used to get the tire's circumference because it is circular.

The circumference of a circle is given by

C = πd

Where C is the circumference and d is the diameter

From the question d = 3.5ft and π = 3.14

∴ C = 3.14 × 3.5

C = 10.99ft

Therefore, the circumference of the tire is 10.99ft

The tire will need to turn 38.2 times to travel the whole length of the street. We will now divide the street's length by the tire's circumference to determine how many times it tire will need to turn to go its whole length.

Number of times the tire will have to turn = Length of the street ÷ Circumference of the tire

Number of times the tire will have to turn = 420 ft ÷ 10.99 ft

Number of times the tire will have to turn = 38.2165 times

Number of times the tire will have to turn ≅ 38.2 times

The total length covered by the outline or boundary of a rectangle is known as the perimeter of the rectangle. And the formula is given by

Where l = length and b = breadth  

Here we have

Rectangle-A and rectangle-B  

Dimensions of Rectangle-A are (x + 2) × x  

=> Perimeter of Recatngle-A = 2(x + 2 + x)

= 2(2x + 2)

Dimensions of Rectangle-B are 4x × 2x  

=> Perimeter of Rectangle-B = 2(4x + 2x)

= 2(6x)    

Given that both rectangles have the same perimeter

=> 2(2x + 2) = 2(6x)

=> 2x + 2 = 6x  [ Divide by 2 ]    

∴ The required equation is 2x + 2 = 6x

The instantaneous voltage across the capacitor is 4/53 * (-cos (106 t - 25)) (volts).

The instantaneous voltage across a capacitor is given by v(t) = 1/C * integral(i(t)dt) where C is the capacitance of the capacitor.

For the current i(t) = 4 sin (106 t - 25), the voltage across the capacitor can be found using the following definite integral:

v(t) = 1/C * integral(4 sin (106 t - 25)dt) from 0 to t

v(t) = 4/106C * (-cos (106 t - 25)) from 0 to t

Answer:

There are 31 quarters.  

There are 47 dimes.  

Step-by-step explanation:

let q = number of quarters

let d = number of dimes

d = 16 + q      

.10d + .25q = 12.45  Multiply through by 100

10d + 25q = 1245       Substitute 16 + q for d

10(16 + q) + 25q = 1245    Distribute the 10

160 + 10q + 25q = 1245  Combine like terms

160 + 35q = 1245  Subtract 160 from both sides

160 - 160 + 35q = 1245 - 160

35q = 1085  Divide both sides by 35

q = 31

There are 31 quarters.    

Substitute 31 for q

d = 16 + 31

d = 47

There are 47 dimes.

Check:

d = 16 + q

47 = 16 + 31

47 = 47  Checks

.10d + .25q = 12.45

.10(47) + .25(31) = 12.45

4.70 + 7.75 = 12.45

12.45 = 12.45  Checks.

Answer:

There are 31 quarters and 47 dimes.

Step-by-step explanation:

To solve this problem, we can create and solve a system of equations.

Define the variables:

Values of the coins:

Given a coin bank contains $12.45 in quarters and dimes:

Given there are 16 more dimes than quarters:

Therefore, the system of equations that represents the problem is:

[tex]\begin{cases} 0.25q + 0.10d = 12.45\\d = q + 16\end{aligned}[/tex]

Substitute the second equation into the first equation to eliminate d:

[tex]0.25q+0.10(q+16)=12.45[/tex]

Solve the equation for q to find the number of quarters:

[tex]\begin{aligned}0.25q+0.10(q+16)&=12.45\\0.25q+0.10q+1.6&=12.45\\0.35q+1.6&=12.45\\0.35q&=10.85\\q&=31\end{aligned}[/tex]

Therefore, there are 31 quarters.

Substitute the found value of q into the second equation and solve for d:

[tex]\begin{aligned}d &= q + 16\\&= 31 + 16\\&= 47\end{aligned}[/tex]

Answer:

Depreciation is the decrease in value of an asset over time. We know that the value of the equipment depreciates at a rate of 20% per year, and after 5 years the equipment is worth $98,304. We can use this information to set up an equation to find the original value of the equipment.

Let X be the original value of the equipment.

We know that:

X * (1 - 0.20)^5 = 98304

Where (1 - 0.20) is the depreciation rate, and the exponent 5 is the number of years.

We can solve for X by using the following steps:

X * (1 - 0.20)^5 = 98304

X * (0.8)^5 = 98304

X = 98304 / (0.8)^5

X = $143,680
