The height of the tree to the nearest foot is 27 feet.

The height of the tree can be found as follows:

The height of the tree can be found using trigonometric ratios. Therefore,

let

tan ∅ = opposite / adjacent

Therefore,

opposite side = adjacent tan ∅

Hence,

height of the tree = 20 + x tan 45° = x tan 75°

20 + x tan 45° = x tan 75°

20 tan 45 + x tan 45° = x tan 75°

20 tan 45 =  x tan 75° -  x tan 45°

20 tan 45 =  x(tan 75 - tan 45)

20 tan 45 = x(3.73205080757 - 1)

2.73205x = 20

x = 20 / 2.73

x  = 7.32600732601

x = 7.34

Therefore,

height of the tree = x tan 75°

height of the tree = 7.34 × tan 75°

Answer: Since triangle QRS and triangle TUV are both triangles, we can use the fact that the sum of the interior angles in a triangle is 180 degrees.

In triangle QRS, the measure of angle Q is 117 degrees and the measure of angle R is 180 - 117 = 63 degrees. The measure of angle S is 180 - 63 = 117 degrees, since the angles in a triangle add up to 180 degrees.

In triangle TUV, the measure of angle T is 180 - 30 = 150 degrees and the measure of angle U is 30 degrees. The measure of angle V is 180 - 150 = 30 degrees, since the angles in a triangle add up to 180 degrees.

The measures of LQ and LS can be found using the fact that the exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

The measure of LQ is equal to the sum of the measures of angles R and T:

LQ = 63 + 150 = 213 degrees

The measure of LS is equal to the sum of the measures of angles Q and U:

LS = 117 + 30 = 147 degrees

So the measure of LQ is 213 degrees and the measure of LS is 147 degrees.

Step-by-step explanation:

The height of the rectangle must be greater than 4 inches if the perimeter of the rectangle is greater than 30 inches.

In geometry, a rectangle is a quadrilateral with four right angles, and opposite sides are equal in length. The perimeter of a rectangle is the total distance around it.

Let's assume that the height of the rectangle is x inches. According to the problem, the base is 7 more than its height, which means the base is (x + 7) inches.

Now, we can calculate the perimeter of the rectangle using the formula:

Perimeter = 2(length + width)

In a rectangle, the length and width are the same as the base and height, respectively. So, in our case, the perimeter of the rectangle will be:

Perimeter = 2(x + (x + 7)) = 4x + 14

As we are given that the perimeter of the rectangle is greater than 30 inches, we can write the inequality:

4x + 14 > 30

Solving for x, we get:

4x > 16

x > 4

The area of the trapezoid would be 42.5 m².

What is the area of a trapezoid?

The area of a trapezoid is given by the formula:

Area = (1/2) × (sum of the bases) × height

where the bases are the two parallel sides of the trapezoid and the height is the perpendicular distance between the bases.

The parameters of the trapezoid are;

Short base length = 3 m

Height = 5

Large base length = 4 + 3 + 7 = 14 m

Thus;

Area of a trapezoid = 1/2 * (Short base + Large base) * h

Area = 1/2 * (3 + 14) * 5

= 1/2 * 17 * 5

= 42.5 m²

Chandra spends 3 minutes on each math problem if she spends a total of 15 minutes on math problems and spends the same amount of time on each problem

Chandra spends the same amount of time on each math problem. Let's call the amount of time she spends on each problem "t".

We know that Chandra spends a total of 15 minutes on math problems. If she spends the same amount of time on each problem, then the total time spent on all the problems is equal to the number of problems multiplied by the time spent on each problem.

So, we can write the following equation:

total time spent on all problems = number of problems * time spent on each problem

We know that the total time spent on all problems is 15 minutes, so we can substitute this into the equation:

15 = number of problems * t

We don't know the number of problems, but we can solve for t by rearranging the equation:

t = 15 / number of problems

So, the amount of time Chandra spends on each math problem is equal to 15 divided by the number of problems.

For example, if Chandra works on 5 math problems, then the amount of time she spends on each problem is:

t = 15 / 5 = 3

So, Chandra spends 3 minutes on each math problem if she spends a total of 15 minutes on math problems and spends the same amount of time on each problem.

The tip of the minute hand on a clock travels approximately 26.4 cm in 11 minutes if the minute hand is 23 cm long.

What is Circle?

A circle is a two-dimensional geometric shape that is defined as the set of all points in a plane that are a fixed distance away from a given point, called the center of the circle. This distance is known as the radius of the circle.

A circle can also be defined as the locus of a point that moves in a plane in such a way that its distance from a fixed point is constant. The constant distance is the radius of the circle.

The minute hand on a clock makes a full rotation in 60 minutes, which means it travels the circumference of a circle with a radius of 23 cm in 60 minutes. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14.

Therefore, the circumference of the circle traced by the tip of the minute hand is:

C = 2πr = 2 × 3.14 × 23 cm ≈ 144.44 cm

To find out how far the minute hand travels in 11 minutes, we need to calculate what fraction of the circumference it covers in that time. Since 11 minutes is about 18.3% of an hour (60 minutes), the minute hand travels 18.3% of the circumference of the circle in that time:

Distance traveled = 0.183 × 144.44 cm ≈ 26.4 cm

Therefore, the tip of the minute hand on a clock travels approximately 26.4 cm in 11 minutes if the minute hand is 23 cm long.

It says that raise school is 1. 7 miles from his house the student walks 17 miles in a 5-day school week

If the school is 1.7 miles from the student's house, then the round trip distance between the house and school is 2 times 1.7 miles, or 3.4 miles per day.

A mile is defined as the unit of length, which is exactly equal to 5280 feet, or 1760 yards, and standardized as exactly 1609.344 meters by the International agreement in 1959. It is the largest unit that is commonly used to measure the distance between places that are far from each other.

To find out how many miles the student walks in a 5-day school week, we can multiply the daily distance by the number of school days in a week:

3.4 miles/day x 5 days/week = 17 miles/week

The function operation (f-g)(x) in the functions f(x) = 2√3x and g(x) = -4√3x is 6√3x and  the value of (f-g)(12) is 36.

A function is simply a relationship that maps one input to one output.

Given that;

First, set up the function;

(f - g)(x) = f(x) - g(x)

Replace the function designators with the actual function.

(f - g)(x) = f(x) - g(x)

(f - g)(x) = 2√3x - (-4√3x)

(f - g)(x) = 2√3x + 4√3x

(f - g)(x) = 6√3x

Now, we evaluate when x = 12.

(f - g)(x) = 6√3x

Replace x with 12

(f - g)( 12 ) = 6√3(12)

(f - g)( 12 ) = 6√36

(f - g)( 12 ) = 6 × 6

(f - g)( 12 ) = 36

If Lin walks at a speed of 2. 5 miles per hour. Andre walks at a speed of 3 miles per hour. It will take 4 hours until Lin and Andre meet on the path.

Lin and Andre are walking toward each other on a 22-mile trail, so they will meet when the sum of the distances they have walked is equal to 22 miles. Let's call the time they walk until they meet "t".

During this time, Lin will have walked a distance of 2.5t miles, and Andre will have walked a distance of 3t miles. The sum of these distances is equal to 22 miles, so we can set up the equation:

2.5t + 3t = 22

Combining like terms, we get:

5.5t = 22

Dividing both sides by 5.5, we get:

t = 4

So it will take Lin and Andre 4 hours to meet on the path.

Note that we could have also solved this problem by using the formula:

time = distance / speed

For Lin, the time to cover the 22-mile distance would be:

time = distance / speed = 22 / 2.5 = 8.8 hours

For Andre, the time to cover the 22-mile distance would be:

time = distance / speed = 22 / 3 = 7.33 hours

Since they are walking towards each other, we can add their times to get the time it takes for them to meet:

time = 8.8 + 7.33 = 16.13 hours

However, we can see that this answer is not correct, as it is greater than the time it would take for either of them to cover the entire distance. This is because the time it takes for them to meet is less than the sum of their individual travel times, due to them moving towards each other.

So we go back to our original equation and solve for "t" to get the correct answer of 4 hours.

Using the vertices given, the area of triangle PQR is 18 squared units

The area of triangle PQR can be found using the Shoelace Theorem. This theorem states that the area of a polygon can be calculated by taking the sum of the products of the coordinates of its vertices and subtracting the sum of the products of the coordinates of its vertices in reverse order.

In this case, the vertices of triangle PQR are P(-8, 2), Q(-2, 4), and R(-6, 8), so the area can be calculated as follows:

A = 1/2 * |(-8 * 4) + (-2 * 8) + (-6 * 2) - (2 * -2) - (4 * -6) - (8 * -8)| = 1/2 * |-32 + 16 + -12 - 4 + 24 + 64| = 1/2 * |36| = 18 square units
