The meaning of the c-value when T=65 is:  The number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

The correct answer is an option (D)

In this question, we have been given a linear relationship.

For a certain type of cricket, this relationship can be expressed using the formula T=34+0.3c,

where T represents the temperature in degrees Fahrenheit and

c represents the number of times the cricket chirps in one minute.

We need to interpret the value of c when T = 65.

T = 34 + 0.3c

65 = 34 + 0.3c

c = 103.33

c = 103.33 represents the number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

Therefore, the meaning of the c-value when T=65 is:  The number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

Here in the rhombus ABCD the value of y is 7.5.

A rhombus is a unique kind of quadrilateral with four equal sides and perpendicular diagonals that cut the angles and one another in half.

So here 4x+15 = 7x+2 and

12y = 90.

To find the remaining values by first solving for each variable, then substituting as necessary.

4x+15=7x+2

15=3x+2

13=3x

13/3 = x

BC is 4x+15

= 4(13/3)+15

= 52/3 + 45/3

= 97/3

CD is 7x+2

= 7(13/3)+2

= 91/3 + 6/3 = 97/3

Then, find 12y=90 and y=7.5.

AFB is a 90° angle (12(7.5)).

BCF is a 4y-1 = 4(7.5)-1 = 29 angle.

Because the diagonal cuts the angle in half, angle BCD is equal to 58. Angle ABC thus becomes 180-58 = 122.

Therefore the value  of  y  is 7.5 .

A) The number of unsold cans of soup (ending inventory) is 19.

B) The various costs of the ending inventory under LIFO, FIFO, and the weighted average are as follows:

                                    Ending Inventory

LIFO                                  $17.15

FIFO                                 $25.65

Weighted average          $21.47

FIFO assumes that the physical flow of goods sold should follow the chronological sequence of purchases or production.

LIFO assumes that the first goods acquired are the last to be sold.

The Weighted Average uses an average to determine the cost of ending inventory and the cost of goods sold.

Description                 Units Unit Cost  Total

Beginning inventory     12     $0.85     $10.20

Purchases                      4     $0.95       $3.80

Total                            37                     $41.75

Sales                            18

Ending inventory        19 (37 - 18)

Average cost = $1.13 ($41.75/37)

LIFO:

Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)

Cost of goods sold = $24.60 ($41.75 - $17.15)

FIFO:

Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)

Cost of goods sold = $16.10 ($41.75 - $25.65)

Answer:

  1/3

Step-by-step explanation:

You want to know the fraction that are poodles when 5/9 of animals are dogs, and 3/5 of dogs are poodles.

We can write the equations ...

  dogs = (5/9)·(animals)

  poodles = (3/5)·(dogs)

Using the first equation to substitute into the second, we get ...

  poodles = (3/5)·(5/9)·(animals) = 3/9·animals = 1/3·animals

Then the fraction that are animals is found by dividing by "animals":

  poodles/animals = 1/3

1/3 of the animals in the pet show are poodles.

Answer:

Yes they are equal

Step-by-step explanation:

First we simplify the left side of the equation

7 x 3,012 = 21084

Next we simplify the right side of the equation. Using PEMDAS we know that we must add whatever is inside the parentheses first.

7 x (3,012)

We then multiply 7 x (3,012) = 21084

21084 = 21084

They are equal.

The equation of line h that passes through (2,6) and is parallel to a line passing through (-3, 4) and (1, 1) is 4y + 3x = 30

Slope is the ratio of the change in the y-coordinates to the change in the x-coordintes of any two given points.

It is a measure of the steepness of a line.

Slope may be positive or negative

slope of the line joining the the points (-3,4) and (1,1)

slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

[tex]x_{1}[/tex] = -3, [tex]x_{2}[/tex] = 1, [tex]y_{1}[/tex] = 4, [tex]y_{2}[/tex] = 1

slope = 1-4 / 1 - -3

slope = -3/4

since the two lines are parallel their slopes are equal.

equation of first line

y = mx + c

where y = 6, x = 2, m = -3/4

6 = -3/4(2) + c

6 = -3/2 + c

c = 6 + 3/2

c = 15/2

Equation, y = -3/4x + 15/2

multiply through by 4

2y = -3x +30

2y + 3x = 30

In conclusion the equation of the line passing through the given point is 2y + 3x = 30

/       =      /

x             15

Just cross multiply, so do 10*15 = 6*x

10*15 = 6*x

150 = 6*x

Divide by 6 on both sides to isolate x.

25 = x

Answer:

x = 25

Step-by-step explanation:

first simplify the 6/15 by dividing 6 and 15 both with 3
10/x = 2/5
then multiply with 5x on both sides to get rid of the fraction:
5x * (10/x) = 5x * (2/5)
then shorten and solve:
5 * 10 = x * 2
50 = x * 2

The relative percentages of the column-wise frequencies are different, indicating that there is indeed an association between the variables.

A user-defined collection of related groups and items is referred to as a data association. It may include one or more groupings, as well as some, all, or neither of the items found inside those groups. It is helpful to initially identify various groups and components that you believe to be connected in some way before establishing Rules of Visibility.

Because of the differences in the relative percentages of the column-wise frequencies, there is a link between the variables. The animal mascot in the first column has 74% victories and 26% defeats. These percentages fluctuate greatly from one another. The other type of mascot, which similarly has a significant disparity between them, has 49% victories and 51% losses. The association between the variables is stronger the larger the difference.

The value of x, given the angles m and n can be found to be 30.

Given the fact that m || n, it means that when m and n are added, they equate to 180 degrees.

The reason for this is that m and n are supplementary angles and such angles will always add up to 180 degrees.

This means the value of x can be found as:

180 = m + n

180 =  (6x - 5 ) + ( x - 25 )

180 = 6x + x - 5 - 25

180 = 7x - 30

Answer:

The 5 consecutive odd integers are 11 , 13 , 15 , 17 , 19

Step-by-step explanation:

The Difference between any odd Integer and its consecutive Integer = 2

So let the 3rd Odd Integer be x

Then the 1st Odd Integer is x - 2

and the 2nd Odd Integer is x - 4

and the 4th Odd Integer is x + 2

and the 5th Odd Integer is x + 4

Since the Sum of the 1st three integers is 3 more than the sum of the last two

Then 1st + 2nd + 3rd = 4th +5th +3

Then (x) + (x - 2) + (x - 4) = (x + 2) + ( x + 4) +3

Then 3x - 6 = 2x + 9

subtract 2x from both sides

3x - 2x -6 = 9

x - 6 = 9

Add 6 for both sides

Then x = 9 + 6 = 15

So the 3rd odd Integer is 15

So the five consecutive odd integers are 11 , 13 , 15 , 17 , 19

The constant of proportionality in the equation c = 8m is 8.

A variation is a relation between a set of values of one variable and a set of values of other variables. Direct variation. In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation.

since C = 8m is an equation and the relationship between c and m is direct.

It means that dividing both sides of the equation by m we have

C/m = 8m/m

c/m = 8

Therefore the constant of proportionality is 8

y = pounds of 52% alloy.

x + y = 45

15.75 - 0.35y + 0.52y = 0.47(45 - y + y)
