Jen wants to buy a dress that originally had the price of $33, but now it is on sale 10% off. How much will Jen pay for the dress

Answer:

Step-by-step explanation:

The constant of proportionality in the equation 2y = 6x is [tex]\( \frac{1}{3} \)[/tex].

In the equation (2y = 6x), the constant of proportionality represents the relationship between x and y. To isolate it, divide both sides of the equation by (6x):

[tex]\[\frac{2y}{6x} = \frac{6x}{6x}\][/tex]

This simplifies to:

[tex]\[\frac{1}{3} = \frac{y}{x}\][/tex]

So, the constant of proportionality is [tex]\(1/3\)[/tex], indicating that for every unit increase in x, y increases by [tex]\(1/3\)[/tex].

Answer:

-3/2

Step-by-step explanation:

The line shown has slope ...

... (y2 -y1)/(x2 -x1) = (-1 -3)/(-3 -3) = -4/-6 = 2/3

The slope of the perpendicular line is the opposite of the reciprocal of this:

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

The price has changed by 37.5% from $120 to $75.

To find the percentage change, we can use the formula:

Percentage change = ((new value - old value) / old value) * 100

In this case, the old value is $120 and the new value is $75. Plugging these values into the formula, we get:

Percentage change = (($75 - $120) / $120) * 100 = (-$45 / $120) * 100 = -0.375 * 100 = -37.5%

Therefore, the price has changed by 37.5%.

The percentage change in price from $120 to $75 is calculated by subtracting the initial price from the final price, dividing the result by the initial price, and then multiplying by 100. The price has decreased by 37.5%.

The question involves calculating the percentage change in price. To do this, you start by subtracting the final price ($75) from the initial price ($120) to determine the difference. In this case, the difference is $120 - $75 = $45. This represents the total change in price.

To find out the percentage change represented by this difference, you divide the difference ($45) by the original price ($120) and then multiply the result by 100 to convert it to a percentage. This can be represented by the formula:
((Final Price - Initial Price) / Initial Price) x 100.

So, the percentage change would be calculated as follows: ((120 - 75) / 120) * 100 = 37.5%. Therefore, the price has decreased by 37.5%.

Answer:

the answer IS 60

Step-by-step explanation:

The sum of the given series  [tex]\sum 4i[/tex]  is 60.

A series can have a sum of each term of the series tends to zero but there are some series in which has each term tends to be zero and do not have a sum.

   5

  [tex]\sum 4i[/tex]  = 4 × 1 + 4 × 2 + 4 × 3 + 4× 4 + 4 × 5

  i=1        = 4 + 8 + 12 + 16 + 20

              = 60

Hence, the sum of the series  [tex]\sum 4i[/tex]  is 60.

To find the total payment Beth will make on her car loan, calculate the total cost using the loan formula. Beth will pay a total of $19,890 in total.

Beth owes $17,000 on her car loan with a 4.25% interest rate, to be paid off over 4 years. To calculate the total amount she will pay, you use the formula for calculating the total cost of a loan: Total Payment = Principal + (Principal x Interest Rate x Time).

Plugging in the values:

Total Payment = $17,000 + ($17,000 x 0.0425 x 4)

Beth will pay a total of $17,000 + ($17,000 x 0.0425 x 4) = $17,000 + $2890 = $19,890 altogether.

The answer is C-3,318.33

Step-by-step explanation:

The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.

I hope this helps!

The equations described in this problem are:

t + u = 9

10t + u = 10u + t - 9

When the two equations are substituted and solved, t = 4 and u = 5.

The original number described in the word problem is 45.

This problem can be solved by creating and solving a quadratic equation based on the Pythagorean theorem. We denote the length of the shorter leg as 'x', and substitute '5x+19' and '5x+20' as lengths of the longer leg and hypotenuse in the theorem.

The entire problem revolves around the application of the Pythagorean theorem, which in a right-angled triangle gives the relationship a² + b² = c², were a and b are the lengths of the shorter sides (legs) and c is the length of the longest side (hypotenuse).

Let's denote the length of the shorter leg as 'x'. From the problem, we know that the longer leg is 5x+19 and the hypotenuse is 5x+20. Using the Pythagorean theorem, we have:

((5x+19)² + x²) = (5x+20)².

You can solve this equation to find out the value of 'x', following which you can substitute this value back into 5x+19 and 5x+20 to find lengths of the longer leg and hypotenuse.

Answer:

The value of the deal should be $40,000.

Step-by-step explanation:

remember that 5% as a decimal is .05.Let x = value of deal

The equation would be .05x = $2000

Divide both sides by 0.05.

x=40,000

y = 200 * (0.75) ^ x
