Evaluate the determinant for the following matrix 

John drank 0.5025 quarts of water at the park and had 0.1675 quarts left over. It's important to note that it's always a good idea to stay hydrated, especially when spending time outdoors, and bringing enough water is key to staying hydrated.

How to solve fraction?

John brought 2/3 quart of water to the park, which can also be expressed as 0.67 quarts. If he drank 3/4 of the water he brought, this means he consumed 0.75 * 0.67 = 0.5025 quarts of water.

To verify this, we can also subtract the amount of water John drank from the amount he brought:

0.67 - 0.5025 = 0.1675 quarts

This means that John had 0.1675 quarts of water left after he drank 3/4 of what he brought.

To summarize, John drank 0.5025 quarts of water at the park and had 0.1675 quarts left over. It's important to note that it's always a good idea to stay hydrated, especially when spending time outdoors, and bringing enough water is key to staying hydrated.

3/8. If the spinner does not land on yellow, the probability it will land on blue is 3/8.

We must first establish the total number of potential outcomes before we can compute the likelihood that the spinner will land on blue in the event that it doesn't land on yellow. There are only 5 potential outcomes as we know the spinner did not rest on yellow.

Two of those five probability are blue. Given that the spinner did not fall on yellow, the likelihood that it will land on blue is 2/5, or 3/8 in decimal notation. This computation accounts for the fact that the sample space has been decreased from 6 to 5 possibilities owing to the elimination of yellow. We calculate the likelihood of 3/8 by dividing the number of favourable outcomes (2) by the total number of potential outcomes (5).

According to given ratios, the inventory turnover for 20Y7 is 4.83 and the inventory turnover for 20Y6 is 5.30.

What is  ratio?

A ratio is a mathematical comparison between two or more quantities. It expresses the relationship between the two quantities by dividing one quantity by the other.

Inventory turnover is a financial ratio that measures how many times a company sells and replaces its inventory over a period of time. It is calculated by dividing the cost of goods sold by the average inventory for the period.

a. To determine the inventory turnover for 20Y7 and 20Y6, we first need to calculate the average inventory for each year:

Average inventory = (Beginning inventory + Ending inventory) / 2

For 20Y7:

Average inventory = ($770,000 + $840,000) / 2 = $805,000

For 20Y6:

Average inventory = ($740,000 + $770,000) / 2 = $755,000

Next, we can calculate the inventory turnover for each year:

Inventory turnover 20Y7 = Cost of goods sold / Average inventory 20Y7

= $3,894,000 / $805,000

= 4.83

Inventory turnover 20Y6 = Cost of goods sold / Average inventory 20Y6

= $4,001,500 / $755,000

= 5.30

Therefore, the inventory turnover for 20Y7 is 4.83 and the inventory turnover for 20Y6 is 5.30.

The equation of the line passing through the points (-1, 5) and (1, -5) is y = -5x.

The collection of points that make up a line in a coordinate system are represented algebraically by a line's equation. The many locations that make up a line on a coordinate axis are denoted by the letters (x, y), and the relationship between x and y results in an algebraic equation that is known as an equation of a line. We can determine whether a given point falls on a line using the equation of any line.

We can use the point-slope form of the equation of a line to solve this problem, which is:

y - y₁ = m(x - x₁)

where:

m = slope of the line

(x₁, y₁) = coordinates of one of the points on the line

First, let's find the slope (m) of the line using the two given points:

m = (y₂ - y₁) / (x₂ - x₁)

m = (-5 - 5) / (1 - (-1))

m = -10 / 2

m = -5

Now we can use one of the points, say (-1, 5), and the slope (-5) to write the equation of the line:

y - 5 = -5(x - (-1))

Simplifying and rearranging the equation:

y - 5 = -5x - 5

y = -5x + 0

Therefore, the equation of the line passing through the points (-1, 5) and (1, -5) is y = -5x.

Answer: See attached for a graph. 13 units apart.

Step-by-step explanation:

      See attached for a graph. We will plot the first point -8 units left and 7 units up. Then we will plot the second point 5 units right and 7 units up.

      Since these points are on a line (they both have the same y-value), we will add the absolute value of their x-values together. We can also count on the graph, you will get the same answer.

|-8| + |5| = 8 + 5 = 13

BC=DE are congruent and the angles are also congruent by using CPCT.

To prove BC=DE given angle BAC=angle DAE, we can use the following steps:

Draw the circle with centre A and points B, C, D, and E on its circumference.

Draw the line segment AE, and extend it to intersect the circle at point F.

Draw the line segment BF, and extend it to intersect the circle at point G.

Draw the line segments CG and DG.

Since angles BAC and DAE are equal, we have angle BAF = angle DAF (because they are vertical angles).

Since angles BAF and BGF subtend the same arc, we have angle BAF = angle BGF.

Similarly, since angles DAF and DGF subtend the same arc, we have angle DAF = angle DGF.

Since angles BGF and DGF are both equal to angle BAC/2 + angle DAE/2, we have angle BGF = angle DGF.

Since angles BGC and DGC are both equal to angle BGF + angle CGF, we have angle BGC = angle DGC.

Since angles BDC and EDC are both equal to angle CGD, we have angle BDC = angle EDC.

Therefore, BC = BG + GC = DG + GC = DE, as desired.

To prove angle BAC=angle DAE given BC=DE, we can use the following steps:

Draw the circle with centre A and points B, C, D, and E on its circumference.

Draw the line segments AC and AD.

Draw the perpendicular bisectors of BC and DE, and let them intersect at point O.

Since BC=DE, the perpendicular bisectors of BC and DE are the same line.

Therefore, point O lies on both the perpendicular bisectors of BC and DE.

Since point O lies on the perpendicular bisector of BC, we have OB = OC.

Similarly, since point O lies on the perpendicular bisector of DE, we have OD = OE.

Since OA is a radius of the circle, we have OB = OD.

Therefore, OB = OC = OD = OE, so quadrilateral BCDE is a kite.

Since a kite has two pairs of equal adjacent angles, we have angle BOC = angle DOE and angle BCO = angle EDO.

Therefore, angle BAC = angle BOC - angle BCO = angle DOE - angle EDO = angle DAE, as desired.

Final outcome is: 1 quart, 2 cups. 2 quarts, 1 pint, and 2 cups are the outcome of removing 1 quart, 2 pints, and 1 cup from 3 quarts and 1 pint.

We must convert all the units to the same level of measurement in order to remove these two mixed volume units. We are aware that 2 pints and 2 cups equal 1 quart. In order to subtract the volumes, we can convert the pint and cup units to quarts.

We begin by converting 1 pint to quarts:

Pints equal half quarts.

The next step is to convert 1 cup to quarts:

1/4 pint is equal to one cup.

Hence, the second mixed unit is:

1.75 quarts are equal to 1 quart, 2 pints, and 1 cup (1 + 2(1/2) + 1/4).

We may now take the volumes away:

3 quarts and a pint minus a pint, a cup, and a quart equals 3 + 1/2 minus 1.75 to 2.75 quarts.

This result can be written as a whole number of quarts plus any leftover pints and cups to return it to mixed units. Since a quart is equal to two pints, we can write:

2.75 quarts equal 2 quarts plus a half-quart.

We may convert the remaining 1/2 quart to pints because 2 cups equal 1 pint:

2 pints from a half-quart

The end result is as a result:

1 quart, 2 cups

Therefore, 2 quarts, 1 pint, and 2 cups are the outcome of removing 1 quart, 2 pints, and 1 cup from 3 quarts and 1 pint.

x = 3 + √(22/3) and x = 3 - √(22/3).

Step-by-step explanation:

Step 1: Divide both sides by the coefficient of x^2 to get the coefficient of x^2 equal to 1.

3x^2 - 18x + 5 = 0

x^2 - 6x + 5/3 = 0

Step 2: Move the constant term to the right-hand side of the equation.

x^2 - 6x = -5/3

Step 3: Take half of the coefficient of x, square it, and add it to both sides of the equation.

x^2 - 6x + 9 = -5/3 + 9

(x - 3)^2 = 22/3

Step 4: Solve for x by taking the square root of both sides of the equation.

x - 3 = ±√(22/3)
