Find the ratio of the longest side to the perimeter of the right-triangular-shaped billboard. 20 feet 21 feet 29 feet
Solution:
we have been asked to find the ratio of the longest side to the perimeter of the right-triangular-shaped billboard.
Sides of the right-triangular-shaped billboard are 20 feet 21 feet 29 feet.
As we know perimeter is just the sum of all the sides.
Perimeter[tex]=20+21+29=70\\[/tex]
And the longest side is 29 feet.
Hence the required ratio [tex]=\frac{29}{70}=29:70[/tex]
Leyla drops a penny from a height of 150m. How long will it take to hit the ground? Round to the nearest tenth of a second. use the formula h(t)=-4.9t²+v₀t+h₀, where v₀ is the initial velocity and h₀ is the initial height.
It will take approximately 5.5 seconds for the penny to hit the ground.
To determine the time it takes for the penny to hit the ground, we can use the given formula for the height as a function of time:
[tex]\[ h(t) = -4.9t^2 + v_0t + h_0 \][/tex]
Given that the penny is dropped and not thrown, the initial velocity [tex]\( v_0 \)[/tex] is 0. The initial height [tex]\( h_0 \)[/tex] is 150 meters. We want to find the time [tex]\( t \)[/tex] when the height [tex]\( h(t) \)[/tex] is 0, which is when the penny hits the ground.
Plugging in the known values, we get:
[tex]\[ 0 = -4.9t^2 + 0 \cdot t + 150 \][/tex] Simplifying, we have:
[tex]\[ 4.9t^2 = 150 \][/tex]
Now, we solve for [tex]\( t \)[/tex]:
[tex]\[ t^2 = \frac{150}{4.9} \][/tex]
[tex]\[ t^2 \approx 30.612244898 \][/tex]
Taking the square root of both sides to solve for [tex]\( t \)[/tex]:
[tex]\[ t \approx \sqrt{30.612244898} \][/tex]
[tex]\[ t \approx 5.532851414 \][/tex]
Rounding to the nearest tenth of a second, we get:
[tex]\[ t \approx 5.5 \][/tex]

how fast is the water level rising in a rectangular fish tank whose base is 20 ft^2 if the tank is being filled at a rate of 0.5ft^3/min
The water level is rising at a rate of 0.025 ft/min.
To determine how fast the water level is rising in the rectangular fish tank, you can use the formula for the volume of a rectangular prism:
V = base area × height
Given that the base area is 20 [tex]ft^2[/tex] and the tank is being filled at a rate of
0.5 cube ft/min, you want to find the rate at which the height (h) is changing [tex](\frac{dh}{dt} )[/tex].
V = base area × height
[tex]\frac{d V}{d t}=\text { base area } \times \frac{d h}{d t}[/tex]
Substitute the known values:
0.5 = 20 x [tex](\frac{dh}{dt} )[/tex]
Now, solve for [tex](\frac{dh}{dt} )[/tex]
[tex]\frac{d h}{d t}=\frac{0.5}{20}[/tex] = 0.025 ft/min
Thus, the required answer is 0.025 ft/min.

A rectangle is 7 feet long by 2 feet wide. If 2 feet are added to the length of the rectangle, what would be the area, in square feet, of the new rectangle?
If a rectangle is 7 feet long by 2 feet wide and 2 feet are added to the length of the rectangle then the area of rectangle is 18 square feet.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given that a rectangle has a length of 7 feet.
The width of rectangle is 2 feet.
We have to find the area of rectangle when 2 feet is added to the length of rectangle
Initial length is 7 feet
When 2 feet is added the length will be 7+2, 9 feet.
Area of rectangle = Length × width
=9×2
Nine times two is eighteen.
=18 square feet.
Hence, if a rectangle is 7 feet long by 2 feet wide and 2 feet are added to the length of the rectangle then the area of rectangle is 18 square feet.

The triangles are congruent by SSS or HL. The diagram shows the sequence of three rigid transformations used to map ABC onto A"B"C". What is the sequence of the transformations? rotation, then reflection, then translation rotation, then translation, then reflection reflection, then translation, then rotation reflection, then rotation, then translation
Answer:- The sequence of the transformations for the given diagram must be reflection, then rotation, then translation.
Explanation:-
Given : Four triangles which are congruent by SSS postulate or HL theorem.
According to the given diagram , the rigid transformations are as follows
1. Reflection: ΔABC is flipped about BC to form ΔA'BC such that AC=A'C and its is already given that they are congruent thus the rigid transformation used here is reflection.
2. Rotation:- ΔA'BC is rotated about point A' at some angle to form ΔA'B'C' , and they are congruent (given). Thus the rigid transformation used here is rotation.
3.Translation:- ΔA'B'C' is translated exactly right by some factor to form ΔA"B"C" ∵ all the points have changed but as these triangles are congruent (given) then corresponding parts must be equal.Thus the rigid transformation used here is translation.
The sequence should be in the order for the given transformation as, reflection, then rotation, then translation. Thus the option D is the correct option.
How to rotate, reflect, and translation the figure?Rotation, reflection and translation is the way of transformation of an figure.
Rotation- Rotation of an object is rotating it about a fixed point without changing its shape and size.Reflection- Reflecting of an object is flipping it across a line without changing its shape and size.Translation- Translation of an object is the shifting of the object without changing its dimensions, without rotating it and without reflecting it.Given information-
In the given diagram the, triangle ABC is transformation into the three stages.
First the figure ABC is just flipped into the triangle A'BC by keeping the side BC fixed.Then the triangle A'BC is rotated around the point A' and to place of A'B'C'.Finally the figure is transact right from one place to another which is A"B"C".Hence the correct sequence of the transformations is reflection, then rotation, then translation. Thus the option D is the correct option.

A horizontal line goes through the point (–7,10). Which statements are true about this line? Check all that apply. The slope of the line is zero. Another point on the line is (3,10). The y-intercept of the line is –7. The equation of the line is y = 10.
The statement 1,2, and 4 are true and 3 is not true below given the reason behind it.
What is a graph?The link between lines and points is described by a graph, which is a diagrammatic representation of a network.
A graph is made up of some points and the distance between two It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.
The given statement is a line passing through ( -7, 10 ) so
Option 1 ⇒ the slope of that line will be zero because it is a horizontal line so it will be true.
Option 2 ⇒another point on this line will be (3,10) since it is a horizontal line so the y coordinate is the same and the x coordinate can vary so it is also true.
Option 3 ⇒ the y-intercept of this line will be 10 which is not true and can be confirmed by options 1 and 2.
Option 4 ⇒ the equation of the line will be y =10 which is true hence it is a horizontal line.
