A total of $6,000 is invested in 2 funds. One of the funds is paying 4% interest and the other is paying 6% interest. The total interest earned in one year was $280. What is the amount of money that was invested in each fund?

The pounds that they would have to each recycle so that they earned the same amount of money from the recycle center is 30 pounds.

Equations that depict the revenue from recycling electronics and appliances are:

The following calculation can be used to calculate how much money Solomon can make by recycling appliances:

p = $0.60a

Solomon's potential earnings from recycling electronics are represented by the equation p = $1.50e - $27.

Here,

p = amount earned

a = pounds of appliances recycled

e = number of electronics recycled

The equation that depicts Solomon's earnings when he makes the same amount of money would be the same as the equation that describes his earnings when recycling gadgets.

$1.50e - $27 = $0.60e

To determine the number of pounds:

Combine and add similar terms

$1.50e - 0.60e = $27

$0.90 = $27

Dividing both sides of the equation by 0.9, we get

$27/ 0.9 = 30 pounds

The price to tile the room is $3,240.

We must figure out how many tiles are required to cover the floor before multiplying that number by the cost per tile to get the cost of tiling the room.

To begin, we must change the room's measurements from meters to centimeters in order to make them consistent with the tile's size. Multiplying 9 by 100 and 7.5 by 100 will yield the results we need: 9m x 100cm/m = 900cm, and 7.5m x 100cm/m = 750cm

Since the room and tile dimensions are now both expressed in centimeters, we can calculate the number of tiles required to cover the space by dividing its size by the tile's area:

25 cm × 20 cm / 36000 cm / 500 cm = (900 cm x 750 cm) / 72

In order to cover the room, 72 tiles are required. We must multiply the quantity of tiles by the price per tile in order to determine the cost:

72 tiles x 45 cents each tile = 3,240

Therefore, the price to tile the room is $3,240.

The value of y in the parallelogram is 120^o.

A parallelogram is a plane figure which has opposite sides to be equal. Some of its properties are:

i. Opposite sides are equal in length

ii. It has two diagonals

iii. Sum of adjacent angles is 180^o

The value of y in the diagram can be determined as;

m<ADC + m<DCB = 180^o              (sum of adjacent angles is 180^o)

(x + 8) + 3x = 180

4x = 180 - 8

    = 172

x = 172/ 4

  = 43

x = 43^o

So that;

m<ADC = x + 8

             = 43 + 8

             = 51^o

Therefore,

m<ADC + m<DAB = 180^o

51^o + (y + 9) = 180^o

The length of the arc intercepted by the central angle of 240 degrees on a circle with a radius of 16 inches would be 67 inches (rounded to two decimal places)

To find the length of an arc on a circle intercepted by a central angle, we can use the formula: arc length = (θ / 360) * (2 * π * r)

where θ is the measure of the central angle in degrees, π is approximately 3.14, and r is the radius of the circle.

In this case, we are given a circle with a radius 16 inches and a central angle of 240 degrees. Plugging these values into the formula, we get:

arc length = (240 / 360) * (2 * 3.14 * 16) = (2/3) * 100.48 = 67 inches

So the length of the arc intercepted by the central angle of 240 degrees on a circle with a radius of 16 inches would be 67 inches (rounded to two decimal places)

Answer:

There are 5 quarters and 1 nickel

Step-by-step explanation:

Let Q and N be the numbers of Quarters and Nickels that Senor Pena found, respectively.

The value of each coin is $0.25 for quarters and $0.05 for each nickel

The total of $1.30 would be the result of:

1)  Quarters:  $0.25*Q, and

2)  Nickels:  $0.05*N

So we can write:  $0.25*Q + $0.05*N = $1.30

We also know he found 6 coins, so:

 Q + N = 6

We have two equations and two unknowns.  We can use substitution to find the answer.

Rearrange the second equation to isolate one of the two variables.  lets isolate Q:

  Q = 6-N

We can use this definition of Q in the first equation by substitution:

$0.25*Q + $0.05*N = $1.30

$0.25*(6-N) + $0.05*N = $1.30

Leaving off the $ signs for clarity:

0.25(6-N) + 0.05N = 1.30

1.5 - 0.25N + 0.05N = 1.30

-0.2N = -0.20

   N = 1

There is 1 nickel

Since  Q = 6-N, Q = 5

There are 5 quarters and 1 nickel

CHECK

Do 5 quarters and 1 nickel add to $1.30?

5*($0.25) + 1*($0.05) = $1.30?

$1.25 + $0.05 = $1.30  YES

The sum of all possible values for the common ratio is -1/2.

The formula for a convergent infinite geometric series is:  Sum  =  a / (1 - r)

where a = first term and r = common ratio.

Given that,

The first term = -3/2  =>   a = -3/2

Since it sums to twice the common ratio,  Sum = 2r.

Putting these together   --->   2r  =  (-3/2) / (1 - r)                      

multiplying both sides by 1 - r:

2r(1 - r)  =  -3/2                              

multiplying both sides by 2:

4r(1 - r)  =  -3                                

multiplying out the left-hand side:

4r - 4r2  =  -3                                  

rearranging the terms:

0  =  4r2 - 4r - 3                              

factor:

0  =  (2r - 3)(2r + 1)

Either  r = 3/2  or  r = -1/2

Since an infinite geometric series converges only when  -1 < r < r,  the possible answer 3/2 must be rejected.

Thus, r = -1/2

Therefore, the sum of all possible values for the common ratio is -1/2.

What is cartesian coordinate system?

A Cartesian coordinate system in a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates. These numerical coordinates are the signed distances from two fixed perpendicular oriented lines to the point, measured in the same unit of length.

Given:

The coordinates of A and B are A(1, 3) and b(-1, 3).

We have to find the coordinates of point C and D.

We know that C and D are directly below A and B respectively. So the x-values must coincide.

Then we can say that:

C = (1, y)

D = (-1, y)

Now, remember that for a rectangle of length L and width W the area is:

A = W*L

In this case, the length is AB, then:

L = 1 - (-1) = 2

And the area is 10 square units, so:

10 = W*2

10/2 = W = 5

This means that:

AC = BD = 5

So the difference between the y-component of A and the y-component of C is 5 units

3 - y = 5

3 - 5 = y = -2

The scale of the model is 0.00017 ft/in, or in inches per foot.

To determine the scale of the model, we need to find the ratio of the size of the model to the size of the real room. We can use the information provided about the total surface area of the model to find this ratio.

The total surface area of the model is given as 2,304 square inches. We can find the total surface area of the real room by multiplying the lengths of the four walls and the floor.

The inside dimensions of the room are given as 8 ft x 12 ft x 8 ft x 12 ft x 8 ft = 8 x 12 x 8 x 12 x 8 = 92,160 sq ft

Now we can find the ratio of the size of the model to the size of the real room by dividing the surface area of the model by the surface area of the real room and converting it to inches per foot.

2,304 sq in / 92,160 sq ft = 0.025 sq in/ sq ft

To convert square inches to square feet we divide by 144, so 0.025 sq in/ sq ft = 0.025/144 = 0.00017 ft/in

Step-by-step explanation:

(A) P(AB) = P(A B) = 0.5 denotes that there is a 0.5 chance that occurrences A and B will occur simultaneously. We cannot tell whether this relationship holds true for these specific events because the provided information does not specify whether A and B are independent or mutually exclusive.

(b) P(A'B) = P(A') + P(B') - P(A'B') = 0.6 denotes that there is a 0.6 chance that events A and B will occur together.

(c) The chance that either the complement of event A or the complement of event B will occur is 0.5. P(A'B') = 1 - P(AB) = 1 - 0.5 = 0.5.

(d) P(A|B) = P(AB) / P(B) = 0.5 / 0.2 = 2.5 denotes that there is a 2.5 percent chance that event A will occur provided that event B has already occurred.

If P(A) = 0.4 and P(B) = 0.2, respectively, then A and B are independent events.

(a) P(AB) is the probability that both occurrences A and B will occur at the same time. It is calculated as P(A) * P(B) = 0.4 * 0.2 = 0.08. The likelihood that A will occur is independent of the likelihood that B will occur since the two events are unrelated.

(b) P(A'B) = P(A') * P(B) = (1-0.4) * 0.2 = 0.12 is the likelihood that events A and B will occur in complement.

(c) The probability that either the complement of event A or the complement of event B will occur, or both, is given by P(A'B') = 1 - P(A'B) = 1 - 0.08 = 0.92.

(d) P(A|B) = P(AB) / P(B) = 0.08 / 0.2 = 0.4, which represents the likelihood that event A will occur in the absence of event B.

if P(A) = 0.4 and P(B) = 0.2, respectively, and A and B are events that cannot coexist.

(a) P(AB) = 0 (by definition of mutual exclusion), indicating that there is no chance that events A and B will occur simultaneously.

(b) The probability that event A's complement, event B, will occur is P(A'B) = P(B) = 0.2.

(c) The probability that either the complement of event A or the complement of event B will occur, or both, is P(A'B') = P(A') + P(B') = 0.6.

(d) Since P(AB) = 0, the probability of event A occurring provided that event B has already occurred is undefined. P(A|B) = P(AB) / P(B) = 0 / 0.2 = undefined.

The first five terms of the sequence [tex]a_n = 3n/(n+4)[/tex] are:

3/5, 3/4, 9/7, 3/2, 15/9.

What is a sequence?

A sequence in A.P stands for "Arithmetic Progression" which is a sequence of numbers in which each term is the sum of the previous term and a constant called the common difference.

Now the given expression is

To find the first five terms of the sequence [tex]a_n = 3n/(n+4),[/tex] we need to substitute the values of n from 1 to 5 and solve for [tex]a_n[/tex].

a1 = 3*1/(1+4) = 3/5

a2 = 3*2/(2+4) = 3/4

a3 = 3*3/(3+4) = 9/7

a4 = 3*4/(4+4) = 12/8 = 3/2

a5 = 3*5/(5+4) = 15/9

Hence, the first five terms of the sequence [tex]a_n = 3n/(n+4)[/tex] are:

3/5, 3/4, 9/7, 3/2, 15/9.
