That means that each hour it drops about 0.0625 inches

Divide the decrease in water level by the length of the time interval.

decrease = 7/12 inches ≅ 0.583 inches

Time interval: From 11 pm to 8:20 am you have 9:20 hours = (9 + 20/60) hours ≅ 9.33 hours

So the water drops at a rate of about

0.583/9.33 inches/hour ≅ 0.0625 inches/hour

Therefore, each hour it drops about 0.0625 inches.

The rate constant, or the specific rate constant, is the proportionality constant in the equation that expresses the relationship between the rate of a chemical reaction and the concentrations of the reacting substances.The rate constant is a proportionality factor in the rate law of chemical kinetics that relates the molar concentration of reactants to reaction rate. It is also known as the reaction rate constant or reaction rate coefficient and is indicated in an equation by the letter k.

Rate constant is dependent on the temperature. For zero-order reaction, rate constant's unit is mol L - 1 s - 1 . For first-order reaction, rate constant's unit is . For second-order reaction, rate constant's unit is mol - 1 L s - 1 .

The measure of each angle is 23 degrees, 67 degrees, and 90 degrees.

The acute angle can be defined as the angle  less than 90°. Or we can say that the angle which is between 0° and 90° is called as an acute angle of a triangle.

Right triangle is also known as right angled triangle. If a triangle has atleast one 90° angle then the triangle is said to be a right angled triangle. A right angle triangle always follows the Pythagoras theorem.

Now, According to statement given :

Let  smaller acute angle = x,

and measure of larger acute angle = 3x-2

Since, it is right triangle the acute angles must be complementary

x + (3x-2) = 90

4x - 2 = 90

4x = 92

x = 23

i.e. smaller acute angle is 23

now second angle = 3x-2 = 3(23) - 2 = 67

and third angle is 90 , as this is a right angled triangle.

Thus, The measurement of each angle is 23 degrees, 67 degrees, and 90 degrees.

Answer:

x = 8

Step-by-step explanation:

the area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] absinC

where a and b are 2 sides of the triangle and C the angle between them

here a = 13 , b = x , C = 30° and A = 26 , then

[tex]\frac{1}{2}[/tex] × 13 × x × sin30° = 26 ( multiply both sides by 2 to clear the fraction )

13x × sin30° = 52 ( using the exact value of sin30° = [tex]\frac{1}{2}[/tex] )

13x × [tex]\frac{1}{2}[/tex] = 52 ( multiply both sides by 2 to clear the fraction )

13x = 104 ( divide both sides by 13 )

The annual depreciation rate is $163.33.

Depreciation rate is calculated using the formula

Annual Depreciation Rate =(Total Depreciable Cost)/(time)    ..where time is in years.

In the given Question

The original cost of item = $500

Cost of item after 3 years = $10

Total Depreciable Cost = (original cost of item) -(Cost of item after 3 years)

=500-10

=$490

So,

Annual Depreciation Amount = (Total Depreciable Cost)/(time)

Annual Depreciation Amount =490/3=163.33

Hence, the item cost would depreciate $163.33 per year.

which means every year the amount will depreciate by $163.33

Therefore, the annual depreciation rate is $163.33 .

We can find whether three points are coplanar by using vector approach.

In geometry, a of group points in space are coplanar if there exists a geometric plane that contains them all. For instance, three points are always coplanar, and if the points are distinct and non-collinear, the plane they exist is unique.

We can check whether the given point F,Q and P are coplanar by first forming vectors of the each given point. The vector form for general point (a,b,c) can be written as [tex]a\hat{i}+b\hat{j}+c\hat{k}[/tex].

The vector forms of point F,Q and P can be given as 'f', 'q' and 'p'. The scalar triple product of the vectors 'f', 'q' and 'p' can be found out by finding the scalar product of vector 'f' with the cross product of the vectors 'q' and 'p' .

An unlimited number of acute triangles can be formed from two sides without an angle measurement, such as a = 10 m and b = 10 m.

As an illustration -

If our side lengths are 10m and 10m, and our angle value goes from 0 to 90 degrees, how many different acute triangles can we create?

Construct a triangle with sides of 10 and 10 metres, an angle of 45 degrees, and a third side that can be extended to the desired length. You have built a triangle.

By changing the third side's length and angle, we can make a whole different triangle that is identical to this one.

Never forget to choose the side lengths and angles. There is a suggestion that you might decide to take a different step. The same angles can be used to make an unlimited number of different triangles.

As a result, with a single angle and a single side length, we can create an endless number of triangles.

Answer: x has no solutions, y has no solutions

Step-by-step explanation:

y = x² - 3

x - y = 1

x - x² - 3 = 1

- x² - x - 3 = 1

- x² - x - 4 = 0

- x² - x - 16/4 = 0

- x² - x - 1/4 - 15/4 = 0

- (x² + x + 1/4) - 15/4 = 0

- (x+1/2)^2 - 15/4 = 0

- (x+1/2)^2 = 15/4

(x+1/2)^2 = -15/4 ==> x has no solutions, y has no solutions

any number to an even power, in this case to the power of 2, has to be positive, but -15/4 is negative.

The following set of numbers 15, 20, and 24 can be the measures of the sides of an acute triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 15, b = 20, and c = 24

a + b > c     15 + 20 > 24     35 > 24     True

a + c > b     15 + 24 > 20     39 > 20     True

b + c > a     20 + 24 > 15     44 > 15      True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

15^2 + 20^2 = 625

2. Compare it to the square of the largest side.

24^2 = 576

625 > 576

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

if they are smaller, then it is an obtuse triangle.

Hence, 15, 20, and 24 can be the measure of the sides of an acute triangle.

The coordinate of point P is -8.

We are given that the endpoints of AB are -16 and -4.

This means that A is at -16 and B is at -4

Therefore, the total length of the line AB will be-

-16 - (-4) = -12 units

But since length cannot be negative, we take only the absolute value, the length of AB comes out to be 12 units.

Now, point P divides AB in the ratio 2:1

The length of these two parts will be

12 × 2/3 and 12 x 1/3

= 8 units and 4 units

This means that AP = 8 units and PB = 4 units

y+2=-2(x-1) is in point-slope form, it is neither in slope-intercept form nor standard form.

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope.
