Based on the cost of the car and the interest rate as well as the period, Jaclyn's monthly payment would be A. $298.81.

First find the amount she financed:

= Cost of car - down payment

= 11,000 - 1,000

= $10,000

Then find the monthly interest and number of periods:

= 4.8%/12                                                          = 3 years x 12

= 0.4%                                                               = 36 months

Monthly payment would be:

Amount financed = Amount x ( 1 - (1 + rate)^-number of periods) / rate

10,000 = A x ( 1 - (1 + 0.4%)⁻³⁶) / 0.4%

10,000 = A x 33.4658758899

Amount = 10,000 / 33.4658758899

= $298.81

In conclusion, option A is correct.

The speed of a boat in still water (b) is 50km/h. It takes the same time (t) for the boat to travel 10km (x) upstream as it does to travel 20km (y) downstream. Find the speed of the current.​

upstream speed (u) = speed in still water (b) - stream speed (s) = b-s = 50-s

downstream speed (d) = speed in still water (b) + stream speed (s) = 50+s

time (t) = x/u = y/d

10/(50-s) = 20/(50+s)

10(50+s) = 20(50-s)

500 + 10s = 1000 - 20s

30s = 500

stream speed (s) = 500/30 = 16.6 km/h

Answer:

y = 9

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 15 when x = 5, thus

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{-15}{5}[/tex] = - 3

y = -3x ← equation of variation

To find the cost of gas for Sally's commute, you would multiply the number of gallons she uses daily by the cost per gallon. Assuming a daily use of one gallon at $4 per gallon, Sally would spend $4 per day, $20 per week (5-day workweek), and $1,040 per year (52 workweeks). This does not account for variable factors such as days off or gas price changes.

The student is asking about the cost of gasoline for commuting to and from a job. Since we do not have the exact distance Sally travels or the efficiency of her vehicle, we cannot compute the exact cost per day, week, or year. However, if we assume Sally uses one gallon of gas per day at a cost of $4 per gallon, here's how you calculate the costs:

These calculations are based on the premise of daily one-gallon gas usage and do not take into account vacations, days off, or possible fluctuations in gas prices.

Answer:

The total cost is calculated to be $105,000.

Step-by-step explanation:

Here,

The cost of per acre land= $60,000

Jack is willing to purchase= 1 ¾acres = [tex]\frac{4*1+3}{4} =\frac{7}{4}=1.75[/tex] acres

Then,

By unitary method,

The cost of one acre land is $60,000 .

The cost of 1.75 acres is    = $[tex]1.75*60,000[/tex]

The total cost of land is =$105,000.

So, Jack has to pay $105,000 to purchase 1.75 acres of land.

To find the total cost of 1 ¾ acres of land purchased at $60,000 per acre, multiply the price by the number of acres. Jack will pay $105,000 for the land.

Jack purchased 1 ¾ acres of land at $60,000 per acre. To calculate the total cost, multiply the price per acre by the total number of acres:

Total Cost = Price per acre x Number of acres

Total Cost = $60,000 x 1.75 = $105,000

120 says is 1/3 of a year.

Interest = 1500 x 0.15 x 1/3 = $75

Proceeds = 1500 - 75 = $1425

Answer: Interest = 1500 x 0.15 x 1/3 = $75

Proceeds = 1500 - 75 = $1425

Answer:

25*3 or 25(3)

Step-by-step explanation:

Understanding arithmetic operations, like multiplication, and the order of operations, is essential in algebra. Parentheses dictate the order, as seen in '2 + (3 x 5)', resulting in 17. For algebraic manipulation, this understanding helps when working with variables and complex expressions like cubing exponentials or solving simultaneous equations.

When faced with the phrase '25 multiplied by 3 algebraic expression', we might interpret this as the task of multiplying an algebraic expression by 25. Considering the examples provided, the manipulation of parentheses greatly influences the outcome of mathematical expressions.

The expression 2 + (3 x 5) includes parentheses, which indicate that multiplication should occur before addition, following the order of operations (PEMDAS/BODMAS). Here, the product of 3 and 5 is 15, and adding 2 results in 17.

However, if we were to apply the principle of algebraic multiplication to an unknown variable, say 'x', the expression would be 25x. If 'x' was the expression (2 + (3 x 5)), then 25x would be 25 times 17, or 425, after applying the order of operations within the parentheses.

Applying this method to simultaneous equations or Cubing of Exponentials, we can see the importance of understanding the principles of algebra and arithmetic operations.

When cubing exponentials, for example, you multiply the exponent by 3. This concept is crucial for solving more complex algebraic problems like those involving unknowns and linear equations.

The division of 5/5/8 by 1/2/9 in simplest form is 405/88 after converting the mixed numbers to improper fractions, then multiplying by the reciprocal, and simplifying.

To find the simplest form of the division of two mixed numbers, first, both mixed numbers must be converted to improper fractions. Dividing by a fraction is the same as multiplying by its reciprocal. So, when dividing 5/5/8 by 1/2/9, we first turn these into improper fractions.

5/5/8 becomes 45/8 (since 5*8+5=45) and 1/2/9 becomes 11/9 (since 1*9+2=11). Now the problem is 45/8 divided by 11/9. To divide these fractions, we multiply by the reciprocal: 45/8 * 9/11 = (45*9)/(8*11) = 405/88.

To simplify 405/88, we find the Greatest Common Divisor (GCD) of the numerator and the denominator, which is 1 in this case, so the fraction is already in its simplest form, which is 405/88.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/2/9 is 9/2/1. So, the expression becomes 5/5/8 multiplied by 9/2/1. To multiply fractions, we multiply the numerators together and the denominators together. So, (5 x 9) / (5 x 2) x 8 / 1 = 45/10 x 8/1 = 360/10 = 36.

The polygon is rhombus

In geometry, the definition of a polygon is given as a closed two-dimensional figure with three or more straight lines. The Greek word "Polygon" consists of Poly meaning "many" and gon meaning "angle". We see many different polygons around us. For example, the shape of a honeycomb is a hexagon. Each polygon is different in structure, they are categorized based on the number of sides and their properties. Thus, all polygons are closed plane shapes.

Given:

angle measures: 80°, 100°, 80°, 100°

As, the sum of angles is 360

= 80+ 80 +100 +100

= 160 +200= 360

Also, pair opposite angles are equal.

Hence, the given polygon is rhombus.

Answer:

43.5 ft

Step-by-step explanation:

Given: Julie is 6 feet tall

           She stands 15 feet from the flagpole.

           The edges of the square line up with the top and bottom of the flagpole.

Picture drawn to show side and angle formed by Julie and flagpole.

Lets assume the height of flagpole be "h".

As given, the edges of the square line up with the top and bottom of the flagpole.

∴ Angle and base of triangle are same then ratio of corresponding sides are also equal.

Now, finding the height of flagpole by using tangent rule.

we know, [tex]tan\theta= \frac{Opposite}{adjacent}[/tex]

Remember, both the angle are equal.

∴ Ratio of opposite and adjacent leg for both right angle triangle= [tex]\frac{6}{15} : \frac{h-6}{15}[/tex]

We can put it; [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]

Solving the equation now

⇒ [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]

Multiplying both side by 15

⇒[tex]6 = \frac{15\times 15}{h-6}[/tex]

Multiplying both side by (h-6)

⇒ [tex]6\times (h-6) = 15\times 15[/tex]

Distributive property of multiplication

⇒ [tex]6h-36= 225[/tex]

Adding both side by 36

⇒[tex]6h= 225+36[/tex]

Dividing both side by 6

⇒[tex]h= \frac{261}{6}[/tex]

∴ [tex]h= 43.5\ feet[/tex]

Hence, the height of flagpole is 43.5 feet.

The height of the flagpole is given by the length of the hypotenuse side

formed by the right triangle Julie forms with the cardboard.

Response:

The triangle formed by the edges of square lined up with the top and

bottom of the flagpole is a right triangle.

The altitude of the right triangle formed with the height of the flagpole as the base = 15 feet

Length of a leg of the right triangle = √(15² + 6²) = 3·√(29)

The other angle formed by the right triangle = (90° - arctan(15/6))

h × sin(arctan(15/6)) = 3·√29

[tex]h = \mathbf{\dfrac{3 \cdot \sqrt{29} }{sin(arctan(15/6))} } = 17.4[/tex]

Height of the flagpole, h = 17.4 feet

The inverse relation of [tex]\( y = 3x + 12 \)[/tex] is [tex]\( x = \frac{y - 12}{3} \)[/tex].

To find the inverse of the relation [tex]\( y = 3x + 12 \)[/tex], we start by expressing it in terms of [tex]\( x \)[/tex] and [tex]\( y \)[/tex]:

[tex]\[ y = 3x + 12 \][/tex]

Next, solve for [tex]\( x \)[/tex]:

22.95

Step-by-step explanation:

91.80÷4=22.95

Therefore, 99.80÷4 is 22.95

The equation with no fractions is:

30x + 80 = 36

Solution:

Given that the equation is:

[tex]\frac{3}{4}x+2=\frac{9}{10}[/tex]

We have to rewrite the equation such that there is no fraction

From given expression,

[tex]\frac{3}{4}x+2=\frac{9}{10}[/tex]

Simplify the left hand side of equation

[tex]\frac{3x+8}{4} = \frac{9}{10}[/tex]

Cross multiply to get a simpler equation

[tex]10(3x+8) = 9 \times 4\\\\Simplify\ the\ above\ expression\\\\30x + 80 = 36[/tex]

Thus the equation is rewritten with no fractions

To rewrite the equation 3/4x + 2 = 9/10 without fractions, we multiply every term by the lowest common denominator (20) to get 15x + 40 = 18. Then, we isolate x by subtracting 40 from both sides to get 15x = -22. We solve for x by dividing both sides by 15, resulting in x = -22/15.

The aim is to rewrite the equation 3/4x + 2 = 9/10 without fractions. To get rid of the fractions, we'll multiply each term by the lowest common denominator (LCD). In this case, the LCD is 20 because it's the smallest number both 4 and 10 can both go into. The equation thus becomes: 20*(3/4x) + 20*2 = 20*(9/10)

This simplifies to: 15x + 40 = 18

Now, to isolate x, we start by subtracting 40 from both sides:

15x + 40 - 40 = 18 - 40

So, 15x = -22. Finally, to solve for x, we divide by 15:

x = -22/15

Common difference = [tex]\frac{1}{5}[/tex]

Solution:

Given arithmetic sequence:

[tex]$-2,-1\frac{4}{5} ,-1\frac{3}{5} , -1\frac{2}{5} , ....[/tex]

Let us first convert the improper fraction into mixed fraction.

[tex]$-2,-\frac{9}{5} ,-\frac{8}{5} , -\frac{7}{5} , ....[/tex]

Difference between two numbers in an arithmetic sequence is the common difference.

[tex]$a_2-a_1=-\frac{9}{5}-(-2)=-\frac{9}{5}+2=\frac{1}{5}[/tex]

[tex]$a_3-a_2=-\frac{8}{5}-\left(-\frac{9}{5}\right)=-\frac{8}{5}+\frac{9}{5}=\frac{1}{5}[/tex]

[tex]$a_4-a_3=-\frac{7}{5}-\left(-\frac{8}{5}\right)=-\frac{7}{5}+\frac{8}{5}=\frac{1}{5}[/tex]

Common difference = [tex]\frac{1}{5}[/tex].

Hence the common difference of the arithmetic sequence is [tex]\frac{1}{5}[/tex].

Common difference of the given arithmetic sequence is equal to [tex]\frac{1}{5}[/tex]

The given arithmetic sequence is in mixed numbers. Converting them into proper fractions, we get:

[tex]First\ term = t_1 = -2\\\\Second\ term = t_2 = -1\frac{4}{5} = -\frac{(5\times1)+4}{5} = -\frac{9}{5}\\\\Third\ term = t_3 = -1\frac{3}{5} = -\frac{(5\times1)+3}{5} = -\frac{8}{5}\\\\Fourth\ term=t_4 = -1\frac{2}{5} = -\frac{(5\times1)+2}{5} = -\frac{7}{5}[/tex]

The sequence can thus be rewritten as [tex]-2, -\frac{9}{5}, -\frac{8}{5}, -\frac{7}{5}[/tex]

To find the common difference of the given arithmetic sequence, subtract any two consecutive numbers of the sequence. The difference between two consecutive numbers is always a constant and is termed as the common difference.

Hence,

[tex]d_1= t_2-t_1=(-\frac{9}{5} -(-2)= \frac{-9+10}{5}= \frac{1}{5} \\\\d_2=t_3-t_2= (-\frac{8}{5} -(-\frac{9}{5} )= \frac{-8+9}{5} = \frac{1}{5}\\\\d_3=t_4-t_3= (-\frac{7}{5} -(-\frac{8}{5} )= \frac{-7+8}{5} = \frac{1}{5}[/tex]

[tex]b=-\frac{1}{2}c^{-2}[/tex] ----> equation B

substitute equation B in equation A

[tex]a=2(-\frac{1}{2}c^{-2})^{3}[/tex]

Applying property of exponents

[tex](x^{m})^{n}=x^{m*n}[/tex]

[tex]x^{-m} =\frac{1}{x^{m}}[/tex]

[tex]a=2(-\frac{1}{2}c^{-2})^{3}=2(-\frac{1}{2})^3(c^{-2})^{3}=2(-\frac{1}{8})(c^{-6})=-\frac{1}{4c^6}[/tex]

therefore

[tex]a=-\frac{1}{4c^6}[/tex]

Part 2) we have

[tex]a=2b^{3}[/tex] ----> equation A

[tex]b=-\frac{1}{2c^{-2}}=-\frac{c^{2}}{2}[/tex] ----> equation B

substitute equation B in equation A

[tex]a=2(-\frac{c^{2}}{2})^{3}[/tex]

Applying property of exponents

[tex](x^{m})^{n}=x^{m*n}[/tex]

[tex]x^{-m} =\frac{1}{x^{m}}[/tex]

[tex]a=2(-\frac{c^{2}}{2})^{3}=2(-\frac{c^{6}}{8})[/tex]
