The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

To find the volume of the cube just cube one of the sides, so 1/8^3 is 1/512

Yes it's the actual volume, it didn't get smaller it's just cubic inches instead of a line.

The rectangle's volume is 1/4*3/8*1/2 which if you change them to have the same denominator it's 2/8*3/8*4/8=3/64

Now convert 3/64 to have a denominator of 512

3/64*8/8= 24/512

24/512 divided by 1/512 is 24

You can fit 24 cubes in the rectangle.

The height of the right cone will be 9.86 units.

The area a cone takes up in a three-dimensional plane is known as its volume. A cone's base is circular, so it is made of a radius and a diameter.

Given that the volume of the cone is 2325 cubic units and the radius of the cone is 15 units.

The height of the cone will be calculated as:-

Volume = 2325

(1/3)πr²h = 2325

( 1/3 ) x π x 15)² x h = 2325

h = ( 2325 x 3 ) / ( 15 x 15 x π )

h = 9.86 units

Therefore, the height of the right cone will be 9.86 units.

Answer: See explanation

Step-by-step explanation:

Negative numbers are greater than other negative numbers with a higher numerical value, for example negative 1 is greater than negative 3.

Negative 10 means 10 below 0.

There is no negative number that is greater than 0.

You write a negative number by putting a subtraction sign before the number. For example, negative 3 would be -3 (or minus 3 from nothing).

1) The area of a circle circumscribed about a square is 307.7 cm².

2.a.) The angle ACB is 39 degrees.°.

2b.) The value of x is 5.42.

We shall find the radius to determine the area of a circle.

First,  find the side length of the square:

Since the perimeter of the square = 56 cm, then, each side of the square is 56 cm / 4 = 14 cm.

Next, find the diagonal of the square, using the Pythagorean theorem:

Diagonal = the diameter of the circumscribed circle.

Diagonal² = side length² + side length²

= 14 cm² + 14 cm²

= 196 cm² + 196 cm²

= 392 cm²

Take the square root of both sides:

Diagonal = √392 cm ≈ 19.80 cm (rounded to two decimal places)

Then, the radius of the circle which is half the diagonal:

Radius = Diagonal / 2 ≈ 19.80 cm / 2 ≈ 9.90 cm (rounded to two decimal places)

Finally, compute the area of the circle using the formula:

Area = π * Radius²

Area = 3.14 * (9.90 cm)²

Area ≈ 307.7 cm² (rounded to two decimal places)

Therefore, the area of the circle that is circumscribed about a square with a perimeter of 56 cm is 307.7 cm².

2. a) We use the property of angles in a circle to solve for angle ACB: an angle inscribed in a circle is half the measure of its intercepted arc.

Given that arc AB has a measure of 78°, we can find angle ACB as follows:

Angle ACB = 1/2 * arc AB

= 1/2 * 78°

= 39°

Therefore, the angle ACB is 39 degrees.

2b.) To solve for the value of x, we use the information that the angle ADB =  (3x - 12)⁴.

Given that angle ADB is (3x - 12)⁴, we can equate it to the measure of the intercepted arc AB, which is 78°:

(3x - 12)⁴ = 78

Solve the equation for x, by taking the fourth root of both sides:

∛∛((3x - 12)⁴) = ∛∛78

Simplify,

3x - 12 = ∛(78)

Isolate x by adding 12 to both sides:

3x - 12 + 12 = ∛(78) + 12

3x = ∛(78) + 12

Finally, divide both sides by 3:

x = (∛(78) + 12) / 3

x = (4.27 +12) / 3

x = 5.42

So, x is 5.42

Therefore,

1) The area of the circle is 154 cm².

2a.) Angle ACB is equal to 102°.

2b.) The value of x is 5.42

the optimal way is to do it with Cramer's rule.

Afterward, simply divide the determinant of variables by the usual determinant.

I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.

The probability that either event A or B will occur is 43/60

Using the parameters given

The probability of each event :

P(A) = 29/60

45 and 27.6 degrees are the two complementary angles.

The various angles or measurements include:

Angles that are complementary are those whose sum is 90 degrees. If the smaller angle has a measure of x, then the complementary angle's measure is 90 - x.

The issue shows that the greater angle (x + 17.4) is 17.4 degrees larger than the corresponding angle's measurement (90 - x). To find x, we can construct the following equation:

x + 17.4 = 90 - x + 17.4

When we simplify and find x, we obtain:

2x = 55.2

x = 27.6

The greater angle's measure is x + 17.4 = 45 degrees, while the smaller angle's measure is x = 27.6 degrees.

The two complementary angles are 27.6 and 45 degrees as a result.

The length of the missing base is approximately 6.67 cm.

By applying the formula for the area of a trapezoid, we will be able to solve for the missing base.

Recall that the formula for the area of a trapezoid is:

A = \(\frac{1}{2} * h * (b_{1} + b_{2})\)

where

A = area

h = height

b₁ and b₂ are the lengths of the parallel bases.

From the question, we are given:

A = 64 m²

h = 12 cm

b₁ = 4 cm.

Plug these values into the formula above to solve the missing base

64 = \(\frac{1}{2} * 12 * (4+ b_{2})\)

Multiplying both sides by 2:

128 = 12(4 + b₂)

Simplifying:

128 = 48 + 12b₂

80 = 12b₂

b₂ = 80/12 = 20/3

b₂ = 6.67

Therefore, the length of the missing base is approximately 6.67 cm.
