Answer:

$250

Step-by-step explanation:

He expected to collect 37.5% less than $400.

First, we find 37.5% of $400.

Then we subtract that amount from $400.

37.5% of $400 is:

37.5% of $400 = 0.375 × $400 = $150

Now, subtract $150 from $400:

$400 - $150 = $250

Answer: $250

The linear speed of a point on the circumference is approximately 9895 feet per minute.

(a) To find the angular speed in radians per minute, we need to convert the given rotational speed from rpm (revolutions per minute) to radians per minute. Since there are 2π radians in one revolution, we can use the conversion factor:

Angular speed (in radians per minute) = Rotational speed (in rpm) * 2π

Given that the rotational speed is 2100 rpm, we can calculate the angular speed:

Angular speed = 2100 rpm * 2π ≈ 13194 radians per minute

Therefore, the angular speed of the wheel is approximately 13194 radians per minute.

(b) To find the linear speed of a point on the circumference in feet per minute, we can use the formula:

Linear speed = Angular speed * Radius

Given that the radius of the wheel is 9 inches, we need to convert it to feet:

Radius = 9 inches * (1 foot / 12 inches) = 0.75 feet

Now, we can calculate the linear speed:

Linear speed = 13194 radians per minute * 0.75 feet ≈ 9895 feet per minute

Therefore, the linear speed of a point on the circumference is approximately 9895 feet per minute.

Answer:

X= 5cm

Y=15cm

Step-by-step explanation:

Using by Pythagoras theorem .

The following relation hold for the dimensions of the triangle;

(Hypotenuse)²=(height)²+(base)²

=> H²=h²+b²

On first triangle the unknown X is the hypotenuse, therefore

X² = 3²+4²

=9+16

x² =25

X=√25

X=5cm

On the second triangle, the unknown Y is the height which is given by ;

h²=H²-b²

=>. Y²= 25²-20²

625-400

Y= √225

=15cm

Answer:

  60

Step-by-step explanation:

The exterior angles of the polygon are the supplement of the interior angles, so are ...

  180° -174° = 6° . . . . measure of each exterior angle

The sum of exterior angles is 360°, so ...

  n(6°) = 360°

  n = 360°/6° = 60

The polygon has 60 sides.

Answer:

The polygon has 60 sides.

Step-by-step explanation:

Each interior angle = 174°

Each exterior angle = 180° - 174° = 6°

Sum of all exterior angles = 360°

6x = 360° (x = no. of exterior angles)

x = 360°/6

x = 60

If it has 60 exterior angles it has 60 interior angles.

None of the given expressions is equivalent to the ㏒2 - ㏒4.

We know that, ㏒(\(x^{n}\)) = n㏒x ........... (i).

Now we have the expression,

㏒2 -㏒4

= ㏒2 - ㏒(\(2^{2}\))

=㏒2 -2㏒2 [Using the formula (i)]

= -㏒2

=log(\(2^{-1}\)) [Using the formula (i)]

=㏒\(\frac{1}{2}\).

Now the first option is ㏒1 which is equal to 0.

The second option is ㏒ 2  which is not equal to ㏒\(\frac{1}{2}\).

The Third option is ㏒(\(^{1}\)) which is 0.

The last option is ㏒(2) +  ㏒(), now We can say  ㏒() means ㏒0 which does not hold any definite value. Hence this option is not correct as well.

Hence, none of the options is correct. Instead, the answer will be, ㏒\(\frac{1}{2}\).

Fast food chains that use plastic or styrofoam containers in selling their products are contributing to the global plastic pollution crisis. Styrofoam and plastic containers, which are not biodegradable, take up to 1000 years to decompose.

Every year, an estimated 8 million metric tons of plastic end up in the ocean, and the majority of it is from single-use plastic products such as those used by fast food chains. This plastic pollution is having a devastating effect on the environment, with marine life ingesting and becoming entangled in the plastic. In addition, the production of styrofoam and plastic containers is highly energy intensive and contributes to the emission of greenhouse gases. This is a problematic situation that needs to be addressed urgently.

The energy intensity of production for styrofoam and plastic containers can be calculated using the formula:

Energy Intensity (EI) = Energy Used (EU) / Output (O)

For example, if it takes 50 kWh of energy to produce a unit of output, the energy intensity of production would be 50 kWh/unit. This highlights the environmental impact of styrofoam and plastic containers, and the urgent need to reduce their use in fast food chains.

The total amount of money in Ms. Jones' account at the end of the twentieth year is $139,379.51.

Ms. Jones deposited $400 at the end of each month for 20 years into a savings account earning 3% interest compounded monthly.

However, she deposited an additional $1000 at the end of the tenth year. The total amount of money in her account at the end of the twentieth year is calculated as follows:

1. First, determine the monthly interest rate:3% annual interest rate/12 months in a year = 0.25% monthly interest rate

2. Next, determine the total number of monthly deposits:20 years x 12 months/year = 240 total monthly deposits

3. Determine the future value of the monthly deposits:We will use the formula for the future value of an annuity with a formula FV = PMT x [(1 + r)n - 1] / r, where:PMT is the monthly deposit ($400)R is the monthly interest rate (0.25%)n is the total number of monthly deposits (240)FV = $400 x [(1 + 0.0025)^240 - 1] / 0.0025= $137,992.83 (rounded to the nearest cent)

4. Determine the future value of the additional deposit in the tenth year :We will use the formula for the future value of a single amount with a formula FV = PV x (1 + r)n, where:PV is the present value of the deposit ($1000)R is the monthly interest rate (0.25%)n is the number of months in the tenth year from when the deposit was made to the end of the twentieth year (120 months).FV = $1000 x (1 + 0.0025)^120= $1,386.68 (rounded to the nearest cent)

5. Add the future value of the monthly deposits in Step 3 to the future value of the additional deposit in Step 4:$137,992.83 + $1,386.68 = $139,379.51

The total amount of money in Ms. Jones' account at the end of the twentieth year is $139,379.51.

Using the bounds for the variables u and v that we found earlier, we can write the integral as: ∫∫R (-2v-5u)^5 (3v+4u)^{-3} dudv = ∫^0_{-1/2} ∫^{3/5}_{-4v/5} (-2v-5u)^5 (3v+4u)^{-3} dudv

We will use a change of variables to simplify the integral. Let:

u = -4x + 5y

v = -3x - 2y

Then, we can solve for x and y in terms of u and v:

x = (-2v - 5u)/29

y = (3v + 4u)/29

Next, we need to find the bounds for the new variables u and v that correspond to the parallelogram R in the xy-plane. The four lines that enclose R become:

-4x + 5y = 0 -> u = 0

-4x + 5y = 3 -> u = 3/5

-3x - 2y = 1 -> v = -1/2

-3x - 2y = 2 -> v = -1

So, the parallelogram R in the uv-plane is defined by:

0 ≤ u ≤ 3/5

-1/2 ≤ v ≤ -1

The integral becomes:

∫ ∫ r -4x^5y-3x^-2ydA = ∫∫R (-2v-5u)^5 (3v+4u)^{-3} |J| dA

where |J| is the determinant of the Jacobian matrix:

|J| = det[∂(x,y)/∂(u,v)] = det[[-5/29 -2/29], [4/29 3/29]] = -23/841

Thus, the integral becomes:

∫∫R (-2v-5u)^5 (3v+4u)^{-3} |-23/841| dudv

= (23/841) ∫∫R (-2v-5u)^5 (3v+4u)^{-3} dudv

Using the bounds for the variables u and v that we found earlier, we can write the integral as:

∫∫R (-2v-5u)^5 (3v+4u)^{-3} dudv

= ∫^0_{-1/2} ∫^{3/5}_{-4v/5} (-2v-5u)^5 (3v+4u)^{-3} dudv

This integral can be evaluated using standard techniques such as integration by substitution. However, it is a rather tedious calculation, and we will not carry it out here.
