At the Culver City Trampoline Park, customers leave their shoes in cubbies shaped like rectangular prisms while they jump. Each cubby is 11 inches deep, 6 inches tall, and has a volume of 396 cubic inches. So, each cubby is 6 inch wide.

Three-dimensional space is quantified by volume. It is frequently expressed as a numerical value using SI-derived units, other imperial units, or American customary units. 

Every object in three dimensions takes up that space. The volume of that kind of area is the one being measured. The area covered by such an object's boundaries in three-dimensional space generally said to as the volume. Other term for it would be an object's capacity.

Given that,

Each cubby is 11 inches deep,

6 inches tall, and

has a volume of 396 cubic inches.

Volume of rectangular prism = L × W × h

or, 396 = 11 × W × 6

or, W = 396 / 66

or, W = 6 inch

Thus, each cubby is 6 inch wide.

Pythagorean theorem \(a^{2} +b^{2} =c^{2}\)

Step-by-step explanation:

\(a^{2} +b^{2} =c^{2} \\x^{2} +3.6^{2} =7.4^{2} \\x^{2} +12.96=54.76\\x^{2} =\sqrt{41.8} \\x=6.47\\\)

The value of x is 6.46 inch.

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

Given: breadth = 3.6, diagonal= 7.4

Using Pythagoras theorem,

H²=P²+B²

(7.4)²= (3.6)²+B²

54.76=12.96 + B²

54.76-12.96=B²

41.8= B²

B= 6.46 inch.

Hence, the value of x is 6.46 inch.

Answer:

E) π/9

Step-by-step explanation:

The angles are complementary meaning they add up to 90°.

Convert radians to degrees:

7π/18 · 180/π = 70°

Now we know that we need the radian equivalent of 20°.

Convert degrees to radians:

70 · π/180 = π/9

Therefore, the measure of the missing degree is π/9.

A cross-segment is a plane segment that is a segment of a three-dimensional item that is parallel to one among its planes of symmetry or perpendicular to considered one of its traces of symmetry.

An instance of a go-segment would be a circle. A cross-section is seen whilst a 3-dimensional picture is reduce through a plane.

Then the case of the cone, a circular go-segment emerges while the cone is cut parallel with its base

The go-sectional region is the location of a 3-dimensional shape which is acquired whilst a three-dimensional object - inclusive of a cylinder - is sliced perpendicular to some designated axis at a point.

The equation of the line passing through two points is given by the point-slope form of the equation of a line, where m is the slope of the line and (x1, y1) is any point on the line. Plugging in the coordinates, we get: m = (-4 - 8) / (-4 - 2)m = -12 / -6m = 2. Now we can use one of the points to write the equation, which is y = 2x + 4.

The slope of the line passing through the points (2, 8) and (-4, -4) is 2.

To find the equation of the line passing through two points, we need to use the point-slope form of the equation of a line. This form is given by:

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is any point on the line.

First, we need to find the slope of the line passing through the points (2, 8) and (-4, -4). The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

m = (y2 - y1) / (x2 - x1)

Plugging in the coordinates, we get:

m = (-4 - 8) / (-4 - 2)

m = -12 / -6

m = 2

Now that we have the slope, we can use one of the points to write the equation of the line. Let's use the point (2, 8). Plugging in the values, we get:

y - 8 = 2(x - 2)

Simplifying this equation, we get:

y - 8 = 2x - 4

y = 2x + 4

Therefore, the equation of the line that passes through the points (2, 8) and (-4, -4) is y = 2x + 4.

Answer:

8.7 feet

Step-by-step explanation:

Use the square area formula, a = s², where s is the side length of the square.

Plug in the area and solve for s:

a = s²

75 = s²

√75 = s

8.7 = s

So, to the nearest tenth of a foot, the height is 8.7 feet

When 1,493,600 is divided by 8 the quotient is 186,700.

To divide 1,493,600 by 8, you can follow these steps:

We have to write down the dividend (1,493,600) and the divisor (8).

Now start with the largest place value in the dividend (the leftmost digit) and perform the division.

Divide 1 by 8. Since 1 is smaller than 8, you move to the next digit.

Bring down the next digit (4) and combine it with the previous quotient (0). This gives you 04.

Divide 4 by 8. Since 4 is smaller than 8, you move to the next digit.

Bring down the next digit (9) and combine it with the previous quotient (0). This gives you 09.

Divide 9 by 8. The quotient is 1, and the remainder is 1.

Bring down the next digit (3) and combine it with the remainder (1). This gives you 13.

Divide 13 by 8. The quotient is 1, and the remainder is 5.

Bring down the next digit (6) and combine it with the remainder (5). This gives you 56.

Divide 56 by 8. The quotient is 7, and there is no remainder.

Bring down the next digit (0) and combine it with the quotient (7). This gives you 70.

Divide 70 by 8. The quotient is 8, and there is no remainder.

There are no more digits to bring down, and the division is complete.

The quotient is the result of the division. In this case, 1,493,600 divided by 8 is equal to 186,700.

Therefore, the result of 1,493,600 ÷ 8 is 186,700.

The probability of observing no positive reading if all suspects are telling the truth is d. 0.59. Probability theory is a branch of mathematics that is used to model and analyze random events.

Probability can be used to predict the likelihood of different outcomes in a wide range of situations, from games of chance to scientific experiments to everyday events. Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain.

To solve this problem, we need to calculate the probability of observing no positive readings given that all suspects are telling the truth, which is equal to the probability that all 5 suspects receive a negative reading on the lie detector test. Since the lie detector will show a positive reading 10% of the time when a person is telling the truth, the probability that a suspect will receive a negative reading when telling the truth is 1 - 10% = 90%. Therefore, the probability that all 5 suspects will receive a negative reading when telling the truth is:

(90%)^5 = (0.9)^5 = 0.59049.

The correct answer is therefore (d) 0.59.

The expression "x > 100" is used to determine the range of values that x can take and the range is all positive integers greater than 100.

An expression is a combination of numbers, variables, and operators that can be evaluated to a numerical value. In this case, the expression "x > 100" is used to determine the range of values that the variable x can take.

The expression checks whether x is greater than 100. If x is indeed greater than 100, then the expression evaluates to True and the next decision in the sequence is reached. If x is not greater than 100, then the expression evaluates to False and the next decision is not reached.

Therefore, the range of values that x can take is all the integers greater than 100. For example, x can be 101, 102, 103, and so on. The range of values for x is not limited, meaning it can be any positive integer greater than 100.

In mathematical terms, the expression "x > 100" can be written as:

x ∈ Z, where Z is the set of all integers and x > 100

In other words, x can be any integer that belongs to the set of all integers, as long as it is greater than 100.

Step-by-step explanation:

You can easily graph this in desmos for a visual understanding.

The slope of a line is received by (y2-y1)/(x2-x1). Assuming that Days is X and the cost is Y, we get (160-90)/(4-2), and it makes 70/2, which equates out to 35. Because the prices become more and more expensive, the slope is positive 35.

The ball hits the ground at a time of 1.433 seconds.

In this problem we have the case of a ball that experiments a free fall, that is, an uniform accelerated motion due to gravity. The position of the ball in time is described by a quadratic equation:

y = y' + v' · t + 0.5 · g · t²

Where:

If we know that y' = 3 m, v' = 5 m / s, g = - 9.807 m / s², y = 0 m, then the time of the ball until it hits the ground is:

0 = 3 + 5 · t - 4.904 · t²

Then, by the quadratic formula:

t = - v' / g ± (1 / g) · √[v'² - 2 · g · y']

t = - 5 / (- 9.807) ± [1 / (- 9.807)] · [5² - 2 · (- 9.807) · 3]

t₁ = 1.433 s. or t₂ = - 0.424 s.
