This number line shows the solution set for the inequality x≥9

Answer:

972

Step-by-step explanation:

Given that QT is the perpendicular bisector of PR.The bisector of any line segment divides it into two equal parts, each of which has the same measure.To begin, let's define a few terms.

Angle bisector - An angle bisector is a line or segment that divides an angle into two equal parts.The given figure is shown below: We are given QT is the perpendicular bisector of PR. That means QT is perpendicular to PR and it bisects it. That is, it divides it into two equal halves.Suppose, PR = 2xFrom the given information, we know that the perpendicular bisector QT divides PR into two equal halves.

So,PQ = QR

Now, In right triangle

TPQ,QT² = TP² + PQ²QT² = TP² + QR² (since PQ = QR)QT² = TP² + (2x)² (since PQ = QR = 2x)QT² = TP² + 4x²

Also, In right triangle

TRQ,QT² = TR² + QR²QT² = TR² + (2x)²QT² = TR² + 4x²

We now have two equations:

QT² = TP² + 4x² QT² = TR² + 4x²

The above two equations can be equated:

TP² + 4x² = TR² + 4x²TP² = TR²

Thus, we can say that

TP = TRLet TP = TR = a

By Pythagoras theorem in right angled triangle

TPQ,TP² + PQ² = TQ²a² + (2x)² = QT²a² + 4x² = QT²

The answer is 4x² + a² = QT².

Answer:

1/16

Step-by-step explanation:

The probability of selecting an Independent on the first draw is 5/16, since there are 5 Independents out of 16 total members.

Assuming that the first person selected is an Independent, there are now 4 Independents left out of 15 total members for the second draw. So the probability of selecting a second Independent given that the first person selected was an Independent is 4/15.

Therefore, the probability of selecting two Independents in succession is:

(5/16) * (4/15) = 1/16

So the probability of selecting two Independents is 1/16 or approximately 0.0625.

The first step is to calculate the total area of 600 bricks.

Area of one brick = 12 inches x 18 inches = 216 square inches

Area of 600 bricks = 600 x 216 = 129,600 square inches

Next, we need to convert the height of the wall from feet to inches since the area of the bricks is in square inches.

10 feet = 120 inches

Now, we can divide the total area of the bricks by the height of the wall to find the length of the wall.

Length of the wall = Area of 600 bricks / Height of the wall
Length of the wall = 129,600 square inches / 120 inches
Length of the wall = 1080 inches

Finally, we can convert the length of the wall back to feet by dividing by 12 since there are 12 inches in a foot.

Length of the wall = 1080 inches / 12 inches/foot
Length of the wall = 90 feet

Therefore, the length of the wall is 90 feet.

To solve this problem, we need to use the formula for calculating area which is length x width. We also need to convert units from feet to inches and vice versa as necessary to ensure we are working with the same units throughout the problem.

The length of the wall is 90 feet.

Answer: Which Option do You Drag and Drop into the Box?

Step-by-step explanation:

Let's call the number of rotations of the larger gear "L" and the number of rotations of the smaller gear "S". We know that when the larger gear completes 1 rotation, the smaller gear completes 1 3/4 rotations.

We can set up a proportion to solve for S:

S/1 3/4 = L/1/4

Simplifying the right side of the equation, we get:

S/1 3/4 = 4L

Multiplying both sides by 7/4 to get rid of the fraction on the left side, we get:

S = 28/4 L

Simplifying, we get:

S = 7L

This means that the smaller gear completes 7 rotations every time the larger gear completes 1 rotation.

Therefore, the correct value to drag and drop into the box is 7.

The value of Tan θ is -5/12

Given that 8 Sin θ = 4 + Cos θ, we need to find Tan θ,

So,

8 Sin θ = 4 + Cos θ

Dividing by Cos θ,

8 Sin θ / Cos θ = (4 + Cos θ) / Cos θ

8 Tan θ = 4 Sec θ + 1

Squaring both sides,

64 Tan² θ = 16 Sec² θ + 1 + 8 Sec θ

64 Tan² θ - 16 Tan θ + 1 = 16 (1 + Sec² θ)

48 Tan² θ - 16 Tan θ - 15 = 0

4 Tan θ(12 Tan θ + 5) -3(Tan θ + 5) = 0

(12 Tan θ + 5) (4 Tan θ - 3) = 0

Tan θ = 3/4 or Tan θ = -5/12

Since Tan θ = 3/4 does not satisfy the equation so Tan θ = -5/12

The gradient of the trail you hiked up is approximately 754.6 ft/mi. This means that for every mile you hiked horizontally, the elevation increased by about 754.6 feet.

The gradient of the trail is essentially the steepness of the trail, or the rate at which the elevation changes per unit of horizontal distance. To find the gradient in ft/mi, we need to calculate the total change in elevation and divide it by the total horizontal distance.
The total change in elevation is the difference between the elevation at the summit and the elevation at the trail head, which is:
6,849 ft - 645 ft = 6,204 ft

The total horizontal distance of the trail is 8.2 mi. To convert the total change in elevation to ft/mi, we divide it by the total horizontal distance
6,204 ft / 8.2 mi = 754.63 ft/mi
Rounding this to the tenths place gives us:
Gradient = 754.6 ft/mi

Answer:

The angle between building 1 and building 3 at building 2 is not a right angle, and hence, the buildings do not form a right triangle.

Step-by-step explanation:

The statement "In the study of logic, p q is to be understood in the exclusive sense, whereby if 'p' and 'q' are both true, the compound claim pvq is, as a whole claim, true" is true.

This principle is known as the exclusive disjunction, which means that the truth value of p v q is only true if either p or q is true, but not both.

In other words, if both p and q are true, then the statement p v q is still considered true because only one of them needs to be true for the whole statement to be true. This concept is essential in the study of logic as it helps to clarify the relationship between different statements and propositions.

Furthermore, this principle is often used in mathematics, computer science, and other fields that rely heavily on logical reasoning. It enables us to make accurate predictions and draw valid conclusions from a set of given premises or statements.

In conclusion, the exclusive disjunction is a crucial concept in the study of logic that helps us understand the truth value of compound claims. Therefore, the statement "In the study of logic, p q is to be understood in the exclusive sense, whereby if 'p' and 'q' are both true, the compound claim pvq is, as a whole claim, true" is true.

In the study of logic, the statement "p ∨ q is to be understood in the exclusive sense, whereby if 'p' and 'q' are both true, the compound claim p ∨ q is, as a whole claim, true" is actually false. This is because the given description refers to the "inclusive" sense of the disjunction (OR) operator, rather than the exclusive sense.

In logic, there are two types of disjunctions: inclusive and exclusive. The inclusive disjunction, represented by p ∨ q, is true when at least one of p or q is true. This means that if both p and q are true, the compound claim p ∨ q is also true, which matches the given description in the question.

On the other hand, the exclusive disjunction, represented by p ⊕ q or p XOR q, is true only when either p or q is true, but not when both are true. If p and q are both true, then the compound claim p ⊕ q is false.

So, the statement in the question actually describes the inclusive disjunction, not the exclusive disjunction, and is therefore false.
