The height of the triangle is 15 feet.
What is the simple definition of a Triangle?A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed. It implies that the interior angles of a triangle add up to 180 degrees. It is the polygon with the fewest sides.
What is a right-angled Triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest side of the three sides, known as the hypotenuse, is the third side.
What is the area of the Right-Angled Triangle?The formula for the area of a right-angle triangle is A = (½)×b×h square units.
Let the height of the triangle be h
Given:- The area (A) of the triangle is 120 ft^2.
The base (b) of the triangle is 16 feet.
From the formula, we know that area of the triangle is:-
A = (½)×b×h
By substituting the values of A and b
[tex]120=\frac{1}{2}*16*h\\ h=(120*2)/16\\h=15[/tex]
Hence the height of the triangle is 15 feet.

- A pole 3.8m high casts a shadow 1.3m long. A nearby tree casts a shadow 4.5m long
A. How tall is the tree, correct to one decimal place? Justify your answer.
The height of the tree is 13.2 m.
What is proportional ?
The concept of proportionality in mathematics denotes the linear relationship between two quantities or variables. The size of one item increases by twofold, whereas the size of the other quantity decreases by one-tenth of the earlier amount.
We can set up a proportion comparing the height of each object to the length of the shadow.
Then , [tex]\frac{h}{s}[/tex].
=> [tex]\frac{3.8}{1.3} = \frac{h}{4.5}[/tex]

a bag contains 14 blue, 6 red, 12 green, and 8 purple marbles. 25 marbles are removed from the bag randomly. how many of the removed marbles were green if the chance of drawing a green marble from the bag is now 3/5?
The number of green marbles removed from the bag is 3.
We will use the Formula of Probability:
In mathematics, the probability is defined as the ratio between the number of favorable outcomes and the total number of outcomes.
p(A) = n(A) / n(S)
p(A) is the probability of event A.
n(A) is the number of outcomes with respect to A.
n(S) is the total number of possible outcomes.
Given in the Question:
A bag contains 14 blue, 6 red, 12 green, and 8 purple marbles.
So the total number of marbles in the bag = 40
It is given that 25 marble are removed from the bag randomly
thus, the remaining marbles in the bag = 40 - 25 = 15
It is given that the probability of drawing a green marble from the bag after removing 25 marbles is 3/5.
So, for finding the number of green marbles in the bag after removing we can write,
n(A) = p(A) × n(S)
here, A is the event of drawing the number of green marbles and p(A) = 3/5 and n(s) = 15 (after removing)
Thus, the number of green marbles in the bag after removing = 3/5 × 15
So, the number of green marbles left in the bag = 9
then, the green marbles removed from the bag = 12 - 9 = 3.
Therefore, only 3 green marbles are removed from the bag.

A. The slope is undefined and the equation of the line is y=12.
B. The slope is zero and the equation of the line is x=3.
C. The dlope is zero and the equation of the line is y=12.
D. The slope is undefined and the equation of the line is x=3.
Slope equals the change in the vertical (Y value) divided by the change in the horizontal (X value), the slope of a horizontal line is zero and equation of line is Y =12. So option C is correct.
What is equation of line?A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis. This value c is known as the y-axis intercept.
Here,
Since the Y-axis is vertical, a line perpendicular to it would be horizontal.. The slope of a horizontal line is zero, because slope is the change in the vertical (Y value) divided by the change in the horizontal (X value), and the vertical coordinate does not change from the -3 of the point given.
If we start with the slope-intercept form of an equation of a line
Y = mX + b,
we can write Y = 0X + (12)
Y =12
Slope is the vertical change (Y value) divided by the horizontal change (X value); the slope of a horizontal line is zero, and the equation of the line is Y =12.

Answer:
Step-by-step explanation:
The number of fliers that he has not posted is 9
What is proportion?
Proportion can be defined as the mathematical comparison of two elements or numbers.
From the information given, we have that;
• Total number of fliers is 45
• First week, 1/3 of the floors were posted
• This week, 3/5 of the remaining were posted.
To determine the number of fliers remaining, we have that;
Remaining fliers for the First week
= 45 × 1/3
Multiply and find the quotient
= 15 fliers
Fliers remaining after the last week
= 15 × 3/5
Multiply and find the quotient
= 45/5
= 9 fliers
Thus, the number of fliers the he has not posted is 9

the measure of the middle ordinate of a yaw mark is 6 ft. the radius of the arc is 70 ft. what was the length of the chord used in this situation? round the answer to the nearest tenth of a foot.
The length of the chord used in this situation is approximately 40.54 ft.
To find the length of the chord used in the situation, we can use the formula for the chord length in a circular arc:
Chord length = 2√(r² - (r - h)²)
where r is the radius of the arc and h is the measure of the middle ordinate.
Given that the radius of the arc is 70 ft and the measure of the middle ordinate is 6 ft, we can substitute these values into the formula:
Chord length = 2√(70² - (70 - 6)²)
Chord length = 2√(4900 - 4489)
Chord length = 2√(411)
Chord length ≈ 2 * 20.27
Chord length ≈ 40.54 ft
