Solve the following proportion for v. v/8=13/11 Round your answer to the nearest tenth.

Answer:

The total affect of the decrease in the interest rate = $29400

Step-by-step explanation:

The initial amount of money which has been deposited into the account = $30000

The rate at which the initial money was deposited = 7%

But it is given that the federal reserve decreases the reserve rate from 7% to 5%

Now, we need to find the affect of this decrease on the deposited money

The rate of change in the interest rate = 7 - 5 = 2%

So, The affect of this decrease = 2% of 30000

                                                    = $600

So, The money becomes = 30000 - 600

Therefore, The total affect of the decrease in the interest rate = $29400

The change in the amount of time that Alejandro studied on the first day to the amount of time he studied on the last day is given by -30 minutes, the correct option is A.

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

Alejandro studied for 6 consecutive days.

Let he studied for x minutes on the first day

Next day he studies (x + 5) minutes.

Each day the time is increasing by 5 minutes.

The equation for time he studied each day = x + 5 t

On last day he studied,

= x + 5 * 6

= x +30

The change in the amount of time that Alejandro studied on the first day to the amount of time he studied on the last day is given by

x - x -30

= -30 minutes

Step-by-step explanation:

Answer: a. Circle

Step-by-step explanation:

Given equation: [tex](x-8)^2+(y-12)^2=25[/tex] which is equivalent to [tex](x-8)^2+(y-12)^2=5^2[/tex]

This equation is of the form [tex](x-h)^2+(y-k)^2=r^2[/tex] which is the standard equation of a circle centered at (h,k) with radius r.

On comparing given equation to the standard equation of  circle we have, h=8 and k=12 and r =2.

Therefore, given equation represent a circle centered at (8,12) and radius=5 units.

Final answer:

A straight line is determined by a minimum of two points. This is a fundamental concept in geometry and algebra, necessary for defining lines on any two-dimensional path or graph.

Explanation:

To determine the minimum number of points through which a straight line is drawn, we need to understand that a straight line is defined by only two points.

The minimum number of points through which a straight line is drawn is two. In geometry, a line extends infinitely in both directions but is determined by just two points. The concept of a line is fundamental in understanding various subjects such as algebra and geometry.

Final answer:

Sonya's annual take-home pay, after FICA taxes of 7.65% on her annual salary of $36,590, would be $33,790.86.

Explanation:

To calculate Sonya’s annual take-home pay after FICA taxes, we first need to understand that FICA consists of two separate taxes: Social Security and Medicare. The total rate for these combined is 7.65% of the gross income. Sonya’s annual salary is $36,590.

First, we calculate the total FICA tax Sonya has to pay:

Add these two amounts to get the total FICA tax:

$2,268.58 (Social Security) + $530.56 (Medicare) = $2,799.14

Finally, subtract this total FICA tax from the annual salary to find Sonya’s take-home pay:

$36,590 (annual salary) - $2,799.14 (FICA taxes) = $33,790.86

Final answer:

Using the two given points $(82, 4)$ and $(42, 9)$, the slope is calculated to be $-1/8$. Subsequently, by using the point-slope form of the line equation and simplifying, we find that the linear relationship between price and demand is described by $y = -1/8x + 57/4$, which corresponds to choice A.

Explanation:

To determine the linear equation that best models the price-demand relationship for the mini-recorders, we are given two points. At a price of $82, the demand is 400 recorders (4 hundred), and at a price of $42, the demand is 900 recorders (9 hundred). In the mathematical representation, these points are (82, 4) and (42, 9), where x is the price and y is the demand in hundreds.

To find the slope (m) of the line, we use the slope formula:

m = (y2 - y1) / (x2 - x1), which gives us m = (9 - 4) / (42 - 82) = 5 / (-40) = -1/8.

Now, we can use the point-slope form to find the equation of the line. Let's use the point (82, 4):

y - y1 = m(x - x1)

y - 4 = (-1/8)(x - 82)

Multiplying out the right-hand side of the equation, we have:

y - 4 = (-1/8)x + (82/8)

y - 4 = (-1/8)x + 10.25

Moving 4 to the other side to get 'y' by itself, the equation becomes: y = (-1/8)x + 10.25 + 4

This simplifies to:

y = (-1/8)x + 14.25

Converting 14.25 into quarters gives us 14.25 = 57/4. Hence the equation becomes:

y = (-1/8)x + 57/4 which matches choice A.

Final answer:

The correct equation that models the price-demand relationship is y = -1/8x + 57/4, where y is the demand in hundreds and x is the price per mini-recorder.

Explanation:

To find the equation that models the price-demand relationship, we need two points to determine the line: (x1, y1) = (82, 4) and (x2, y2) = (42, 9). The demand, y, is in hundreds of recorders and x represents the price per mini-recorder. The slope (m) of the line is given by the change in demand over the change in price: m = (y2 - y1) / (x2 - x1) = (9 - 4) / (42 - 82) = 5 / (-40) = -1/8. To find the y-intercept (b), we use one of the points and the slope in the linear equation formula y = mx + b. Using the point (82, 4), we have 4 = (-1/8)(82) + b. Solving this equation gives us b = 4 + (1/8)(82) = 4 + 10.25 = 14.25. Now the linear equation is y = -1/8x + 14.25. Since y needs to be in hundreds for the units to match the point given (400, 900), we must divide b by 100, resulting in b = 14.25 / 100 = 57/4. The final price-demand relationship is y = -1/8x + 57/4.

Answer:

The answer is the B)

Step-by-step explanation:

By the definition, in a function, a value in the first set of numbers only have a value in the second set of numbers, so for every pair of numbers, we have to review if the first number for this pair only appears one time in all the function.

All the set ot values agrees with this definition except the B, because the third and fourth pair have the same first value (3)

To convert a fraction to a decimal, divide the numerator by the denominator. For example, 1/2 converted to a decimal is 0.5.

To convert a fraction to a decimal, you use the method defined by option B: Numerator divided by Denominator (Numerator / Denominator). This will give you the decimal equivalent of the fraction. For example, if you have the fraction 1/2, you divide the numerator (1) by the denominator (2) to get 0.5, which is the decimal equivalent of the fraction 1/2.
