In geometry, a prism is a three-dimensional solid shape that consists of two congruent bases (which can be any polygon) and a set of parallel line segments that connect the corresponding vertices of the two bases. The bases are usually parallel and of the same shape and size, and the line segments connecting the vertices are known as the lateral faces of the prism.

Prisms are commonly found in architecture and engineering, where they are used to create structures such as buildings, bridges, and towers. They are also used in optics, where they are used to refract and reflect light, and in mathematics, where they are used to study geometric properties and relationships.

To find the total space that the energy prisms will take up, we need to multiply the number of prisms by the amount of space each prism takes up. We can use scientific notation to simplify the calculation:

3.5 x 10⁵ energy prisms * 2 x 10² cubic feet per prism

= (3.5 * 2) x 10⁵⁺² cubic feet

= 7 x 10⁷ cubic feet

Therefore, the total space that the cargo will take up is 7 x 10⁷ cubic feet.

Therefore, the probability of Mrs. Vo winning is 1 - 91/300 - 8/21 = 11/30.

Probability refers to the likelihood or chance that a particular event or outcome will occur. It is a mathematical concept that quantifies the degree of uncertainty associated with an event or situation. Probability is typically expressed as a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that it is certain to occur.

by the question.

let's consider the first case: Mrs. Vo spins a number greater than 65 on her first spin. There are a total of 8 numbers greater than 65 on the wheel: 70, 75, 80, 85, 90, 95, 100. Since there are 21 sections on the wheel, the probability of spinning a number greater than 65 on the first spin is 8/21.

The number of possible outcomes for Mrs. Vo's spin is 21, since there are 21 equal portions on the wheel. However, we need to exclude the outcomes that would cause Mrs. Vo's sum to exceed 100, since that would result in an automatic loss. The largest possible outcome on the wheel is 100, so Mrs. Vo cannot spin a number greater than or equal to 35 on her first spin.

The number of outcomes that would give Mrs. Vo a winning sum of at least 66 is the number of outcomes greater than 65, which are 70, 75, 80, 85, 90, 95, and 100. There are 7 such outcomes.

If Mrs. Vo spins a number less than or equal to 65 on her first spin, the probability of this happening is 13/21. The probability of her second spin being between 1 and 35 is 35/100 (since there are 35 numbers between 1 and 35 on the wheel). So, the probability of her total sum being less than or equal to 65 is (13/21) * (35/100) = 91/300.

The volume of the sphere is approximately 33.51 cubic centimeters.

The volume of a sphere can be calculated using the formula:

V = (4/3)π[tex]r^{3}[/tex]

where r is the radius of the sphere

V is the volume of the sphere

Since the diameter of the sphere is 4 centimeters, the radius is half of that, or 2 centimeters.

Plugging this value into the formula, we get:

V = (4/3)π([tex]2^{3}[/tex])

V = (4/3)π(8)

V = (32/3)π

The evaluation of expression 7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2) and simplification to get the final result of 2√5 - 2√6 + 6.

To evaluate the expression is

7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2)

we need to rationalize the denominators of each fraction. To do this, we can multiply both the numerator and denominator of each fraction by the conjugate of the denominator.

For the first fraction, we can multiply the numerator and denominator by (√10 - √3):

7√3(√10 - √3) / [(√10 + √3)(√10 - √3)]

Simplifying the denominator gives:

7√3(√10 - √3) / 10 - 3

For the second fraction, we can multiply the numerator and denominator by (√6 - √5):

-2√5(√6 - √5) / [(√6 + √5)(√6 - √5)]

Simplifying the denominator gives:

-2√5(√6 - √5) / 6 - 5

For the third fraction, we can multiply the numerator and denominator by (√15 - 3√2):

-3√2(√15 - 3√2) / [(√15 + 3√2)(√15 - 3√2)]

Simplifying the denominator gives:

-3√2(√15 - 3√2) / 15 - 9

Now, we can simplify each expression separately and then combine them:

7√3(√10 - √3) / 7 = √30 - 3

-2√5(√6 - √5) / 1 = -2√6 + 2√5

-3√2(√15 - 3√2) / 6 = -√30 + 9

Combining the expressions gives:

√30 - 3 - 2√6 + 2√5 - √30 + 9

Simplifying further gives:

2√5 - 2√6 + 6

Therefore, the value of the expression 7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2) is 2√5 - 2√6 + 6.

If b is not equal to 0, an ordered pair of numbers a and b, denoted as a / b, is a ratio and the ratio in the given situation is 3a:2b = 6:1.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0.

A proportion is an equation that sets two ratios at the same value.

For instance, if there is 1 boy and 3 girls, you may express the ratio as 1: 3 (there are 3 girls for every boy), meaning that there are 1 in 4 boys and 3 in 4 girls.

Ratios contrast two figures by ordinarily dividing them. A/B would be your formula if you were comparing one data point (A) to another data point (B).

So, we know that:

a+b/a-b = 5/3

Now, solve as follows:

3 ( a + b) = 5 ( a - b)

3 a + 3 b = 5 a - 5 b

5 b + 3 b = 5 a - 3 a

8 b = 2 a

2 a = 8 b

a = 4 b

3 a = 3 × 4 b

3 a = 12 b

3 a: 2 b = 12 b : 2 b

Then: 3a:2b = 6:1

The area of the triangle with vertices (-1, 1), (-1, 5), and (4, 1) is 10 square units.

The area of a triangle is a measure of the amount of space inside the triangle. It is defined as half the product of the base of the triangle and its corresponding height.

If a triangle has base length b and corresponding height h, then its area A is given by the formula:

A = (1/2) × b ×h.

In the given question,

To find the area of the triangle with vertices (-1, 1), (-1, 5), and (4, 1), we can use the formula: A = (1/2) × b ×h.

where the base is the distance between two vertices of the triangle and the height is the perpendicular distance from the third vertex to the base.

We can choose any two points as the endpoints of the base, but it may be easiest to use the points (-1, 1) and (4, 1), since the height will be the vertical distance from the third vertex (which is ( -1, 5)) to the base.

The distance between (-1, 1) and (4, 1) is: base = 4 - (-1) = 5

To find the height, we need to determine the perpendicular distance from the point (-1, 5) to the line containing the base. This can be done by finding the equation of the line containing the base and then finding the distance from the point (-1, 5) to that line.

The equation of the line containing the base is: y = 1

since the line is horizontal and passes through the point (4, 1) and (-1, 1).

The distance from the point (-1, 5) to the line y = 1 is:

height = |5 - 1| = 4

where the absolute value is taken to ensure that the height is positive.

Now, we can substitute the values of the base and height into the formula for the area:

Area = (1/2) × base × height

= (1/2) * 5 * 4

= 10

Therefore, the area of the triangle with vertices (-1, 1), (-1, 5), and (4, 1) is 10 square units.

The dimensions of the box are 30 cm by 50 cm by 25 cm.

Area is a measure of the amount of space enclosed by a two-dimensional object, such as a shape or a surface. It is usually expressed in square units, such as square meters (m²), square inches (in²), or square centimeters (cm²), depending on the unit system used.

Let x be the side length of the squares that are cut out of each corner of the cardboard.

When the squares are cut out and the sides are folded up, the resulting box will have dimensions (80-2x) cm by (100-2x) cm by x cm.

The area of the base of the box is:

(80-2x) cm × (100-2x) cm = 8000 - 360x + 4x² cm²

We know that the area of the base is 4000 cm², so we can set this equal to the expression we just found:

8000 - 360x + 4x² cm² = 4000 cm²

Simplifying and rearranging, we get a quadratic equation:

4x² - 360x + 4000 = 0

Dividing both sides by 4, we get:

x² - 90x + 1000 = 0

This quadratic can be factored as:

(x - 40)(x - 25) = 0

Therefore, the possible values of x are x = 40 cm and x = 25 cm.

If we use x = 40 cm, then the dimensions of the box are:

Length = 80 - 2x = 0 cm (not possible)

Width = 100 - 2x = 20 cm

Height = x = 40 cm

If we use x = 25 cm, then the dimensions of the box are:

Length = 80 - 2x = 30 cm

Width = 100 - 2x = 50 cm

Height = x = 25 cm

Therefore, the dimensions of the box are 30 cm by 50 cm by 25 cm.

The answer is  option (A)  BC=YZ ,to show that AABC = AXYZ by ASA, we need to know that angle C is congruent to angle ∠Y, angle ∠Z is congruent to angle ∠B, and BC is congruent to ZY.

An angle is a geometric figure formed by two rays with a common endpoint, called the vertex of the angle. The two rays are called the sides of the angle, and they can be named in any order. The measure of an angle is the amount of rotation needed to bring one of the rays into alignment with the other.

To show that AABC = AXYZ by ASA, we need to show that two angles and the included side of one triangle are congruent to two angles and the included side of the other triangle. Since we are given that ZZZC and CB ZY, we know that angle ∠C is congruent to angle ∠Y, and angle ∠Z is congruent to angle ∠B. Therefore, we need to find another piece of information that shows that the included sides are congruent.

Looking at the diagram, we can see that side BC is congruent to side ZY, since they are opposite sides of a rectangle. Therefore, we have BC = ZY, which means that statement A, BC=YZ, is true.

So, to show that AABC = AXYZ by ASA, we need to know that angle ∠C is congruent to angle ∠Y, angle ∠Z is congruent to angle ∠B, and BC is congruent to ZY. Since we have all three of these conditions, we can conclude that AABC = AXYZ by ASA.

Answer:

sin(theta) = -3/5.

Step-by-step explanation:

We know that tan(theta) = 3/4, which means that the ratio of the opposite side to the adjacent side of a right triangle with angle theta is 3/4. We can use the Pythagorean theorem to find the hypotenuse of the triangle:

hypotenuse^2 = opposite^2 + adjacent^2

hypotenuse^2 = (3^2) + (4^2)

hypotenuse^2 = 9 + 16

hypotenuse^2 = 25

hypotenuse = 5

Since 180 degrees < theta < 270 degrees, we know that theta is in the third quadrant, where the sine function is negative. Therefore, sin(theta) = -opposite/hypotenuse = -3/5.

So, sin(theta) = -3/5.

An exponential function can be used to model this situation.

In this case, we know that each hour following the initial dose, 80% of the concentration remains in the body from the preceding hour. This means that the amount of penicillin remaining in the body is decreasing exponentially.

We can use the formula for exponential decay, which is:

A = A0 * e^(-kt)

where A is the amount of penicillin remaining in the body at time t, A0 is the initial amount of penicillin (in this case, 500 milligrams), k is the decay constant, and e is the mathematical constant approximately equal to 2.718.

The decay constant, k, can be calculated using the following formula:

k = ln(0.8)

where ln is the natural logarithm.

So the exponential function that can be used to model this situation is:

A = 500 * e^(-0.2231t)

where t is the time in hours since the initial dose was administered.

This function will give us the amount of penicillin remaining in the body at any time t, based on the initial dose and the rate of decay.

We can conclude after answering the provided question that Therefore, diameter m GFH = 21° and m GZH = 116°.

In geometry, the diameter of a circle is any straight line segment that has an endpoint on the circle and travels through its centre. Another way to put it is the longest chord of a circle. Either concept can be used to define the diameter of a sphere. The diameter is the length of the line that runs tangent to the two points at either end of the circle. If you consider length to be the distance between two points, diameter equals length. The diameter of a circle is the distance between its two furthest points.

We know that angle EGF is a right angle (90°) because EG is a diameter.

Given that m FG = 116°, we can calculate m FGE by subtracting it from 180° (the sum of triangle angles):

m FGE = 180 degrees - m FG = 180 degrees - 116 degrees = 64 degrees

m GFH = 180° - m ZGF - m ZGFH = 180° - 90° - 69° = 21°

Finally, we can calculate m GZH by subtracting m FGE from 180° (the sum of triangle angles):

180° m GZH - 180° m FGE - 64° = 116°

Therefore, m GFH = 21° and m GZH = 116°.
