The number of months that it would take for the price of the gallon to get to 1.90 dollars is 20 months.

We have the following details with which we are to solve this problem.

The price of gas is given as $1.79

The rate of increase is given as 0.3% = 0.003

We are to find the value for when it would be $1.90

The formula that would be used to solve this is given as

[tex]F = P * (1 + r)^n[/tex]

Where f = final value

p = present value

r = rate

n = number of months

From the question

f = 1.90

p = 1.79

r = 0.03

we have to put these values in the formula that we have here

[tex]1.9 = 1.79 * (1 + 0.03)^n[/tex]

[tex]1.9 = 1.79 * (1.003)^n[/tex]

Divide through by 1.79

[tex]\frac{1.9}{1.79} = (1.003)^n[/tex]

take the ln of both sides

[tex]ln\frac{1.9}{1.79} = nln(1.003)[/tex]

We have to simplify the equation above from this stage

ln1.0615 = n0.002995

0.05968 = n0.002995

divide through by the value of n

n = 0.05968 / 0.002995

n = 19.92

n ~ 20

After the subtraction, the simplified value is 16 hours : 9 minutes : 22 seconds

Subtraction

Subtraction means the process of finding the difference between two or more numbers.

Given,

Here we have the timings.

9h 24min 13s

-6h 45min 9s

Now, we have to perform the subtraction on it and also write it in the simplified form.

In order to perform the subtraction, we have to convert the given timings into decimal form, then we get,

=> 9h 24min 13s = 9.4036

Similarly, the second one is converted as decimal form, like

=> - 6h 45min 9s = -6.7525

Now, we have to perform the subtraction on it,

=> 9.4036 - (-6.7525)

=> 16.1561

Now, we have to convert this into time format, then we get,

=> 16 hours : 9 minutes : 22 seconds

The cost for 1 hot dog is $2.25  and the cost for 1 bag of potato chips is  $1.5   .

In the question ,

it is given that ,

a vendor is selling  hot dogs and bags of potato chips ,

the customer bought 5 hot dogs and 4 bags of potato chips for $17.25

let the cost of 1 hot dog = h    and

let the cost of 1 bag of potato chips = p

So , the equation is 5h + 4p = 17.25

and another customer buys , 2 hot dogs and 2 bags of chips

So , the equation is , 2h + 2p = 7.50

2p = 7.50 - 2h

and 4p = 15 - 4h

Substituting 4p = 15 - 4h in the equation 5h + 4p = 17.25 , we get

5h + 15 - 4h = 17.25

h + 15 = 17.25

h = 17.25 - 15

h = 2.25

and 4p = 15 - 4h

4p = 15 - 4(2.25)

4p = 15 - 9

4p = 6

p = 6/4

p = 1.5

Therefore , The cost for 1 hot dog is $2.25  and the cost for 1 bag of potato chips is  $1.5   .

Step-by-step explanation:

Each year you need to multiply the employee's current salary by 4% (in decimal form this is 0.04). Then you add the result to their current salary.

Year 1

40000 * 0.04 = 1600

40000 + 1600 = 41600

Year 2

41600 * 0.04 = 1664

41600+ 1664 = 43264

Year 3

43264 * 0.04 = 1730.56

43264+ 1730.56 = 44994.56

Year 4

44994.56 * 0.04 = 1799.78

44994.56+ 1799.78 = 46794.34

Year 5

46794.34 * 0.04 = 1871.77

46794.34+ 1871.77 = 48666.11

Year 6

48666.11 * 0.04 = 1946.64

48666.11+ 1946.64 = 50612.75

Year 7

50612.75 * 0.04 = 2024.51

50612.75+ 2024.51 = 52637.26

Step-by-step explanation:

1/5 of 30 is 6

1/2 of 6 is 3

The match of the equation are listed below:

A. y = 1.5x => (14,21) ,(2,3), (8, 12)

B. 2x + 3y = 7 => (1, 1 2/3), (-1, 3), (0, 2 1/3)

C. x - y = 4 => (-3, -7), (0, -4), (-1, -5)

D. 3x = y/2 => (0.5, 3), (1, 6), (1.2, 7.2)

E. y = - x + 1 => (1/2, 1/2), (1/4, 3/4), (1/8, 7/8)

Equation:

Equation refers the statement that the values of two mathematical expressions are equal and indicated by the equal sign.

Given,

Here we have list of equation and the matching solutions also.

Now, we need to find the correct pairs from it.

In order to find the correct matching pair, in each solution we have to take one point and apply it on the given equation, then we get,

Then when we take the point (14,21)

Apply it on the equations, then we get,

A. 21 = 1.5(14)

=> 21 = 21

Now, we have to take the second one (-3, -7)

And apply it on the equations,

B . 2(-3) + 3(-7) = 7

=> -6 - 21 = 7

=> -27 ≠ 7

C. -3 - (-7) = 4

=> -3 + 7 = 4

=> 4 = 4

Then the third point (1/2, 1/2), the apply the equation,

B. 2(1/2) + 3(1/2) = 7

=> 1 + 3/2 = 7

=> 5/2 ≠ 7.

D. 3(1/2) = (1/2)/2

=> 3/2 ≠ 1

E. y = -x + 1

=> 1/2 = -1/2 + 1

=> 1/2 = 1/2

Now, we have to take the point (-1, 3)

B. 2(-1) + 3(3) = 7

=> -2 + 9 = 7

=> 7 = 7

The circumference of ΔAOC, ΔAOB and ΔABC are  4√2(1+√2), 2(√5+3) and 2(3+√5+2√2) units respectively and area of ΔAOC, ΔAOB and ΔABC are 8,4 and 12 square units respectively.

The perimeter of a triangle can be calculated by simply adding the length of all the sides.

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.

There are three triangle in the given diagram namely ΔAOC, ΔAOB and ΔABC.

We will find the area and circumference of each of the triangle.

First we find area of each triangle.

Area of ΔAOC = 1/2*CO*AO = 1/2*4*4 = 8 square units.

Area of ΔAOB = 1/2*BO*AO = 1/2*2*4 = 4 square units.

Area of ΔABC = 1/2*BC*AO = 1/2*6*4 = 12 square units.

Now, we will find circumference of each triangle.

Since,  ΔAOC, ΔAOB are right angled triangle

⇒    AC = [tex]\sqrt{AO^{2}+OC^{2} }[/tex] = [tex]\sqrt{4^{2}+(-4)^{2} }[/tex] = [tex]\sqrt{32}[/tex] = 4√2 units.

and AB = [tex]\sqrt{AO^{2}+OB^{2} }[/tex] = [tex]\sqrt{4^{2}+2^{2} }[/tex] = [tex]\sqrt{20}[/tex] =2√5 units.

Circumference of ΔAOC = AC+CO+AO = 4√2+4+4 =4√2+8 = 4√2(1+√2) units.

Circumference of ΔAOB = AB+BO+AO = 2√5+2+4 =2√5+6=  2(√5+3)units.

Circumference of ΔABC = AB+BC+AC = 2√5+6+4√2 = 2(3+√5+2√2)units.

Therefore, circumference of ΔAOC, ΔAOB and ΔABC are  4√2(1+√2), 2(√5+3) and 2(3+√5+2√2) units respectively and area of ΔAOC, ΔAOB and ΔABC are 8,4 and 12 square units respectively.

The angle θ = 170° and  θ = 350°  have the same Sine and Cosine as 10° respectively

Since the Sine and Cosine of angle 10° are positive

In order to find an angle θ with 0° < θ < 360° that has the same Sine and

Cosine as 10°, we have to check the quadrants in Trigonometry where Sine and Cosine are positive

1st quadrant (0° - 90°) => Sine is positive (10° is here)

2nd quadrant (91° - 180°) => Sine is positive

3rd quadrant (181° - 270°) => None is postive

4th quadrant (271° - 360°) => Cosine is positive

We will consider the 2nd and 4th quadrants:

2nd quadrant: Sine 10° = Sine (180 - 10)° = Sine 170°

4th quadrant: Cosine 10° = Cosine (360 - 10)° = Cosine 350°

The annual percentage yield (APY) of Rocio is 3.11 %

What is Annual Percentage Yield?

The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest.

Given data ,

Deposit amount of Russ = $ 3200

Interest rate R = 3.1 %

And it is given that the interest rate is compounded daily , so

Interest rate R = 3.1 % / 365

                       = 0.031 / 365

                       = 0.000084

Now , The annual percentage yield (APY) is calculated as

The interest amount = 3200 x ( 1 + 0.000084 )³⁶⁵

                                 = 3200 x ( 1.000084 )³⁶⁵

                                 = 3200 x 1.031133

                                 = 3299.6272

                                 ≈ 3299.627

Therefore , the interest will be

= 3299.627 - 3200

Now , the annual percentage yield (APY) is given by

= Interest / Deposit

= 99.627 / 3200

The fundamental quality of capitalism is the desire to make a profit.

Capital, which developed from capitale, a late Latin term based on caput, meaning "head," is where the word "capitalism" originates. Chattel and cattle, both of which allude to moveable property, also have their roots in capital (only much later to refer only to livestock).

A capitalist economy allows for the private ownership and control of capital assets like mines, railroads, and factories. It also allows for the purchase of labor for monetary wages, the accrual of capital gains to private owners, and the allocation of prices.

2) In second circle radius is 46 inch and diameter is 92 inch

3)In third circle radius is 23 ft and diameter is 46ft

What's the radius solution?

The radius formula is easily obtained by halving the circle's diameter. The line segment created when we join a point on a circle's circumference to its exact center is referred to as the ring's radius. The radius of a circle is the separation between its center and circumference.

What is diameter, for instance?

If you look at the cycle wheel, the spikes that run through the center from one end to the other are an illustration of diameter. This is comparable to the diameter of a circle, which is the line segment that extends from one end of the circle to the other end while passing through the center of the circle.
