It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

6 teaspoons of vinegar = 15 teaspoons of olive oil.

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Now,

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 2 on both sides.

2 teaspoons of vinegar = 5 teaspoons of olive oil.

Now,

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 8 on both sides.

8 teaspoons of vinegar = 20 teaspoons of olive oil.

Now,

Total number of teaspoons = 42

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 12 on both sides.

12 teaspoons of vinegar = 30 teaspoons of olive oil.

12 + 30 = 42 teaspoons

Now,

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 4 on both sides.

4 teaspoons of vinegar = 10 teaspoons of olive oil.

4 + 10 = 14 teaspoons

Thus,

2 teaspoons of vinegar are needed for 5 teaspoons of olive oil.

8 teaspoons of vinegar are needed for  20 teaspoons of olive oil.

There are 12 teaspoons of vinegar and 30 teaspoons of olive oil in the 42 teaspoons of salad.

The tangent point of the line, given the center of the circle can be found to be  ( 5.39, -10.07).

We have the equation of the tangent line as 4x + 5y = -29 and the center of the circle as (-2, 4).

Equation of the line containing the radius as:

y - 4 = (5/4)(x - (-2))

y - 4 = (5/4)(x + 2)

Solving the system of equations:

y = (-4/5)x - 29/5

y - 4 = (5/4)(x + 2)

Eliminate y by substituting the first equation into the second:

(-4/5)x - 29/5 - 4 = (5/4)(x + 2)

Now, solve for x:

(-4/5)x - 29/5 - 20/5 = (5/4)x + 10/4

(-4/5)x - (5/4)x = 10/4 + 49/5

(-16/20)x - (25/20)x = 25/4 + 196/20

(-41/20)x = 221/20

x = 221/41

Now, find the y-coordinate by plugging the value of x into one of the equations. Let's use the first equation:

y = (-4/5)(221/41) - 29/5

y = (-884/205) - 1181/205

y = -2065/205

The tangent point is (221/41, -2,065/205) or ( 5.39, -10.07).

The numeric value of the exponential expression in this problem is given by the following option:

A. 2^12.

The exponential expression for this problem is defined as follows:

8^x/2^y.

8 is the third power of 2, hence:

8 = 2^3.

When a term is elevated to two of it's powers, the powers are multiplied, hence:

(2^3)^x = 2^(3x).

Meaning that the exponential expression is then written as follows:

8^x/2^y = 2^(3x)/2^y.

When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:

2^(3x)/2^y = 2^(3x - y).

As stated in the problem, the numeric value of the expression 3x - y is given as follows:

3x - y = 12.

Hence the entire expression is simplified as follows:

2^(3x - y) = 2^12.

Meaning that the correct option is given by option A.

Answer:A. 2^12.

Step-by-step explanation:i did it and got it right

The equation of the ellipse is \((x - 3)^2 / 16 + (y - 3)^2 / 64 = 1.\)

To determine the equation of the ellipse, we need to find its major and minor axes, as well as the distance from each focus to the center.

Given that the foci of the ellipse are located at (3, 1) and (3, 5), we can determine that the center of the ellipse is at the midpoint between these two foci, which is (3, 3).

The endpoints of the minor axis are (7, -2) and (-1, -2), which tells us that the length of the minor axis is 7 - (-1) = 8 units.

Now, let's calculate the distance from the center to one of the foci. Using the distance formula, we have:

sqrt((3 - 3)^2 + (3 - 1)^2) = sqrt(0 + 4) = 2.

Since the foci are vertically aligned, the major axis is vertical. Therefore, the length of the major axis is twice the distance from the center to one of the foci, which gives us 2 \(\times\) 2 = 4 units.

Using the standard form of the equation for an ellipse centered at (h, k), with a horizontal major axis of length 2a and a vertical minor axis of length 2b, the equation is:

\((x - 3)^2 / 4^2 + (y - 3)^2 / 8^2 = 1.\)

Answer:

1 pound of Oranges = $2

1 pound of Bananas = $2

Step-by-step explanation:

O = Oranges

B = Bananas

=> 5o + 2b = 14

=> 2b = 14 - 5o

=> b = 14/2 - 5/2o

=> b = 7 - 2.5o

3o + 6b = 18

=> 3o + 6( 7 - 2.5o ) = 18

=> 3o + 42 - 15o = 18

=> -12o + 42 = 18

=> -12o = -24

=> -o = -2

=> o = 2

One pound of oranges costs $2.

So,

5 (2) + 2b = 14

=> 10 + 2b = 14

=> 2b =4

=> b = 2

One pound of bananas also costs $2.

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

We are given a figure in which several angles are shown

We are asked to provide an alternate name for the angle 5.

Please note that when two rays meet at a common point then an angle is formed.

The angle 5 is between two rays E and F.

The common point where E and F meet is V.

We start from one endpoint then common point then the other endpoint.

So the angle will be called FVE

Therefore, option B is correct.

Why other options are wrong?

Option A) VEF

We don't start with the common point that's why it is wrong.

Option C) FEV

The common point must be in the middle so that's why it is wrong

Option D) FVC

The angle 5 is between F and E but here it is between F and C that's why it is wrong.

The mean number of minutes per movie in the given sample is 117.

The correct answer is option E.

To find the mean number of minutes per movie, we need to calculate the average length of the 10 movies provided.

Given movie lengths: 101, 134, 149, 81, 149, 101, 134, 101, 149, 81

To find the mean, we sum up all the movie lengths and divide by the total number of movies:

Sum of movie lengths = 101 + 134 + 149 + 81 + 149 + 101 + 134 + 101 + 149 + 81 = 1170

Number of movies = 10

Mean = Sum of movie lengths / Number of movies = 1170 / 10 = 117

Technically, you would write this as 5 < x < 3, however, this is a false inequality, and does not work.

Bad debt expense is $8,500. So, Statement is true.

As per calculation of bad debt expense based on percentage of sales method, bad debt expense recognized is the percentage of credit sales irrespective of any balance in allowance for doubtful account.

Balance in allowance for doubtful debt is not considered at all.

In this case, credit sales = $800,000

Estimation of uncollectible account = 1%

Convert the percentage to decimal numbers by dividing with 100.

We get:

= \($\frac{1}{100}\)

= 0.01

Bad debt expenses can be calculated as:

= 0.01 × 800,000

= $8,000

Adjusting the entry to the record bad debt expense is:

Bad debt expense......................Dr         $8,000

      Allowance for doubtful debt                               $8,000

(Bad debt expense recognized)

The new balance in allowance for doubtful account

= 8,000 + 500

= $8,500

The amount of bad debt expense to be recorded in the adjusting entry is $8,500 and new balance in allowance for doubtful account is also $8,500.

Answer: The transformation g(x) = f(2x) will produce the values given in the g(x) column of the table.

Step-by-step explanation: The transformation of f(x) that will produce g(x) is g(x) = f(2x).

In the given table, we can observe that the values of g(x) are equal to the corresponding values of f(x) when x is multiplied by 2. This indicates that g(x) is obtained by applying a horizontal compression or shrinking to f(x) by a factor of 2.

By substituting 2x into the function f(x), we can see that the values match those in the g(x) column:

f(2x) = f(-4) = 5

f(2x) = f(-2) = 2

f(2x) = f(0) = 1

f(2x) = f(2) = 5

f(2x) = f(4) = 10

Hence, the transformation g(x) = f(2x) will produce the values given in the g(x) column of the table.
