Answer: Acute Triangle

Step-by-step explanation:

Because when we look at it we can actually see each of the angles, they are less than 90 degrees then they are consider as acute angles, if it's greater than 90 degrees and smaller than 180 degrees then it will be consider as a obtuse, and if it's equal to 90 degrees then it's a right angle. This is not a equiangular, if it's then it should be have three 60degrees angles.

The change in elevation will be 12 feet.

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario. It is vital to note that an equation is a mathematical statement which is made up of two expressions that are connected by an equal sign.

The four criteria that can be used to prove triangles are congruent and can be used to prove the triangles are congruent.

Triangle congruence: Two triangles are said to be congruent if all three of their corresponding sides and all three of their corresponding angles have the same measurements. These triangles can be moved around, rotated, flipped, and turned to have a same appearance. They match up with one another when moved.

The four criteria that can be used to prove triangles are congruent are SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and SSS (Side-Side-Side). Additionally, CPCTC (Corresponding Parts of Congruent Triangles are Congruent) can be used to prove the triangles are congruent.

The required markup from the cost of $270 is 20% of the sale price.

The selling price of an item is ​$360. It is marked down by ​%10, but this sale price is still marked up from the cost of ​$270.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
Selling price after 10% marked down,
= [1 - 0.10] × 360
= 324
Now,
Percentage marked up of cost price of $270
= 324 - 270 / 270 × 100
= 20%

Thus, as of the given condition markup cost of $270 is 20% of the sale price.

Answer:

To determine if there is a proportional relationship between the temperature in degrees Celsius and the temperature in degrees Fahrenheit, we need to see if the ratio of the temperature in degrees Celsius to the temperature in degrees Fahrenheit is constant.

On the first day, the ratio of the temperature in degrees Celsius to the temperature in degrees Fahrenheit is 20°C / 68°F = 5/17.

On the second day, the ratio of the temperature in degrees Celsius to the temperature in degrees Fahrenheit is 10°C / 50°F = 1/5.

Since the ratio of the temperature in degrees Celsius to the temperature in degrees Fahrenheit is different on the two days, there is not a proportional relationship between the temperature in degrees Celsius and the temperature in degrees Fahrenheit.

Step-by-step explanation:

Since both data points satisfy the proportional relationship equation, we can conclude that there is a proportional relationship between the temperature in degrees Celsius and the temperature in degrees Fahrenheit.

To determine if there is a proportional relationship between the temperature in degrees Celsius (°C) and degrees Fahrenheit (°F), we can check if the data points given for both temperatures satisfy the proportional relationship equation:

°F = (9/5) * °C + 32

Let's calculate the proportional relationship using the given data points:

1. First data point: 68°F and 20°C

  °F = (9/5) * 20 + 32

  °F = 36 + 32

  °F = 68

  The first data point (68°F and 20°C) satisfies the proportional relationship equation.

2. Second data point: 50°F and 10°C

  °F = (9/5) * 10 + 32

  °F = 18 + 32

  °F = 50

The second data point (50°F and 10°C) also satisfies the proportional relationship equation.

         /         \

      /               \

H /                      \ J                       K

Now,

m∠JHI = (x+12)

m∠HIJ = (x−3)

m∠IJK = (5x−6)

The sum of the angles in the triangle IHJ is 180 degrees.

m∠JHI + m∠HIJ + m∠IJH = 180

x + 12 + x - 3 + m∠IJH = 180

2x + 9 + m∠IJH = 180

2x + m∠IJH = 180 - 9

2x + m∠IJH = 171

m∠IJH = 171 - 2x ____(1)

Now,

m∠IJK = 180 - m∠IJH

5x - 6 = 180 - m∠IJH

m∠IJH = 180 - 5x + 6

m∠IJH = 186 - 5x _____(2)

Now,

From (1 ) and (2) we get,

186 - 5x = 171 - 2x

186 - 171 = 5x - 2x

15 = 3x

x = 5

Now,

The value of m∠IJK.

The coordinate of the circumcenter of a triangle is (1,3).

Here we have to find the coordinates of the circumcenter of a triangle.

Given data:

The vertices of the triangle are:

A = (0,1)

B = ( 2,1)

C= ( 2,5)

The formula to find the distance between the two points:

Distance = [tex]\sqrt{(x2 - x1)^{2} + (y2-y1)^{2} }[/tex]

In the same manner distance between AB, BC, and AC are:

AB = [tex]\sqrt{(2-0)^{2} + (1-1)^{2} }[/tex]

    = 2

BC = [tex]\sqrt{(2-2)^{2} + (5-1)^{2} }[/tex]

      = 4

AC = [tex]\sqrt{(2-0)^{2} + (5-1)^{2} }[/tex]

     = 2√5

So by the Pythagoras, we get to know that the triangle is a right-angle triangle.

The circumcenter of a right-angle triangle is the midpoint of the hypotenuse.

Midpoint of AC = (0+2)/2 , (1+5)/2

                         = 2/2, 6/2

                         = 1,3

The two numbers whose difference is 86 and whose product is a minimum. The numbers are (43,-43) and therefore, the smaller number is  -43 and largest number is 43.

Given :

Two numbers whose difference is 86 and whose product is a minimum.

To find : The numbers

Let the largest number be x,

and smallest number be y.

According to question,

Two numbers whose difference is 86.

i.e.  x - y = 86                   -----------------------------(1)

Product of two number is minimum.

i.e.   xy = 86                     -------------------------------- (2)

where P is minimum.

Now substitute x from (1) in (2),

     x (x -86) = P

⇒ y(x) = x² - 86x = P               ------------------------------ (3)

Differentiating Equation (3), we get:

y'(x) = 2x - 86

and y'(x) = 0

After subtracting we get:

    2x - 86 = 0

⇒ x = 86 /2

⇒ x = 43

The vertex of the equation occur at x = 43.

Putting the value of x = 43 in equation (1) , we get:

    48 - y = 86

⇒ -y = 86 - 48

⇒ y = -43

So, the value of y is - 43.

Therefore, the numbers are (43,-43).

The angle x of the isosceles triangle is 64 degrees.

The side and angle of the similar polygon are 7.5 units and 20 degrees.

The triangle above is an isosceles triangle. An isosceles triangle is a triangle that has 2 sides equal to each other and two angles equal to each other.

Therefore, the base angle of the isosceles triangle are equal.

Hence,

52 + x + x = 180

52 + 2x = 180

2x = 180 - 52

2x = 128

x = 128 / 2

x = 64 degrees

Similar polygons are two polygons with the same shape, but not the same size.  Similar polygons have corresponding angles that are congruent, and corresponding sides that are proportional.

Therefore, let's find x and y in the polygon.

x / 5 = 6 / 4

cross multiply

4x = 30

x = 30 / 4

x = 7.5

y - 73 = 360 - 90 - 61 - 116

y - 73 = 93

y = 93 - 73

y = 20

Therefore, the angle x of the isosceles triangle is 64 degrees and the sides x of the polygon is 7.5 units and the angle y of the polygon is 20 degrees.

Answer:

1,728 small cubes are needed to completely fill a larger cube with side lengths of 30 cm.

Step-by-step explanation:

Answer:

To find the volume of water that was pumped from container A, we first need to find the volume of each container. We can use the formula for the volume of a cylinder to do this. The formula is V = πr^2h, where r is the radius of the cylinder and h is the height.

For container A, the volume is V = π * 13^2 * 18 = 8640π cubic feet

For container B, the volume is V = π * 11^2 * 20 = 7320π cubic feet

Since the water from container A completely filled container B, the volume of water that was pumped from container A is 8640π - 7320π = 1320π cubic feet.

To find the percent of container A that is full, we need to divide the volume of water remaining in container A by the total volume of container A and multiply by 100%. The total volume of container A is 8640π cubic feet, and after the water was pumped into container B, the volume of water remaining in container A is 8640π - 1320π = 7320π cubic feet.

Therefore, the percent of container A that is full is 7320π / 8640π * 100% = approximately 84.9% to the nearest tenth.

The limit of x/|x|  as x approaches 0 does not exists.

We need to find the limit of x/|x| as x approaches 0.

Consider left hand limit.

lim x -> 0- (x/|x|)

x/|x| = -1 for all negative values of x.

So, lim x -> 0- (x/|x|) = -1

Consider right hand limit.

lim x -> 0+ (x/|x|)

x/|x| = 1 for all positive values of x.

So, lim x -> 0+ (x/|x|) = 1

lim x -> 0- (x/|x|) ≠ lim x -> 0+ (x/|x|)
