The statement does not make sense. A triangle cannot have two right angles as the sum of the three angles in a triangle is always 180 degrees. Two right angles would add up to 180 degrees, leaving no room for the third angle.
To determine the number of plants needed, first find the perimeter of the square flower bed by multiplying the length of one side by 4 (since there are four sides in a square). 8 x 4 = 32 feet. Then convert the spacing of 8 inches to feet by dividing by 12 (since there are 12 inches in a foot). 8 / 12 = 0.67 feet. Finally, divide the perimeter of the flower bed by the spacing of the plants to get the total number of plants needed. 32 / 0.67 = 47.76. Round up to the nearest whole number to get the final answer of 48 plants.

Find the extract value of x
Answers
Answer:
25 + 5√29
Step-by-step explanation:
(I added a photo below)
First, let's find BC using the Pythagorean theorem (from ∆BCD):
[tex] {bc}^{2} = {25}^{2} + {10}^{2} = 625 + 100 = 725[/tex]
[tex]725 > 0[/tex]
[tex]bc = \sqrt{725} =5 \sqrt{29} [/tex]
Then we see, that AB = 25 + x
So, now we can find AC:
[tex] {ac}^{2} = ({25 - x})^{2} - ({5 \sqrt{29} })^{2} = 625 - 50x + {x}^{2} - 25 \times 29 = 625 - 50x + {x}^{2} - 725 [/tex]
Now we have a quadratic equation:
[tex] {x}^{2} - 50x - 100 = 0[/tex]
[tex]d = {b}^{2} - 4 \times a \times c = ({ - 50})^{2} - 4 \times 1 \times ( - 100) = 2500 + 400 = 2900 > 0[/tex]
[tex]x1 = \frac{ - b - \sqrt{d} }{2a} = \frac{50 - 10 \sqrt{29} }{2} = 25 - 5 \sqrt{29} [/tex]
This is a negative number and we cannot use it, since x has to be a natural number
[tex]x2 = \frac{ - b + \sqrt{d} }{2 a} = \frac{50 + 5 \sqrt{29} }{2} = 25 + 5 \sqrt{29} [/tex]
Peyton drew a right triangle with sides 5

cm, and 13
cm long. Carter drew a similar triangle to Peyton’s. Which of the following can be the measurements of Carter’s triangle?
Answers
Option B. The length of the hypotenuse of Carter's triangle is 13cm.
Since Carter's triangle is similar to Peyton's triangle, the ratio of corresponding side lengths will be the same. Let's use x to represent the length of the hypotenuse of Carter's triangle.
We know that the ratio of the lengths of the hypotenuse and the shorter leg of Peyton's triangle is 13:5. So, the ratio of the lengths of the hypotenuse and the shorter leg of Carter's triangle must also be 13:5.
Thus, we have x/5 = 13/5, which simplifies to x = 13.
Therefore, the length of the hypotenuse of Carter's triangle is 13cm.
Therefore, the only possible length for Carter's hypotenuse is 13cm, and the correct answer is A.

The height after t seconds of a projectile that is launched upward with a velocity of 64 feet per second from the top of a 45 foot building is given by. When will the projectile attain a height of 85 feet?
Answers
The projectile will attain a height of 85 feet at approximately 0.775 seconds or 3.225 seconds.
Calculating the Time to reach a certain heightGiven that
Velocity = 64 feet per second --- v
Initial height = 45 feet --- h
The height function can be represented as
h(t) = -16t² + vt + h
So, we have
h(t) = -16t² + 64t + 45
where h is the height in feet and t is the time in seconds.
To find when the projectile will attain a height of 85 feet, we need to solve the equation for t
So, we have
-16t² + 64t + 45 = 85
-16t² + 64t - 40 = 0
Using a graphing tool, we have
t = 0.775 and t = 3.225
Therefore, the projectile will attain a height of 85 feet at approximately t = 0.775 seconds or t = 3.225 seconds.

Rajan baut a book for Rs 180 and sold it to sajan at a profit of 20%. Sajan sold that book to nirajan at a lost 20%. At what price nirajan should sell the book to receive 5% profit ?
Answers
Solution,
CP for rajan=180 rs
Sp for rajan=(20%+1)×180
=216
Cp for niranjan=216
And, Sp=.8×216
=172.8
Cp for niranjan=172.8
For 5% profit,
Sp for Niranjan=(5%+1)×172.8
=181.44
Hence, for Niranjan to gain 5% profit, he must sell it for 181.44 rs
Answer - 181.44
Explanation - For Rajan,
Cost Price = Rs 180
Profit Percent = 20%
Profit Percent = (S.P - C.P/C.P)*100
20 = (S.P - 180/180) *100
S.P = Rs 216
For Sajan,
C.P = Rs 216
Loss Percent= 20%
Loss = (C.P - S.P/C.P)*100
20 = (216-S.P/216)*100
S.P = Rs 172.8
For Niranjan to Sell Book and get 5% profit,
C.P = Rs 172.8
Profit Percent = (S.P - C.P/C.P)*100
5 = (S.P-172.8/172.8)*100
S.P = 181.44

The vertices of ∆A′B′C′ are A′(-6, 5), B′(-6, 8), and C′(-10, 5) upon the application of the translation rule.
What is the translation rule in geometry?
In geometry, a translation is a transformation that moves every point of a figure the same distance in the same direction. In the case of a triangle, a translation rule describes how to move each vertex of the triangle to a new location to create a new triangle with the same size and shape, but in a different position.
A translation rule for a triangle is given by a pair of numbers (a, b), which indicate the amount of horizontal and vertical movement of the vertices. Specifically, the rule is given by the formula:
(x, y) → (x + a, y + b)
This formula means that we move every point in the triangle a unit to the right or left (depending on the sign of a) and b units up or down (depending on the sign of b).
The translation rule (x, y) → (x − 3, y + 4) means that we move every point in the original triangle left by 3 units and up by 4 units. So, the translation is described as a leftward shift of 3 units and an upward shift of 4 units.
To find the vertices of ∆A′B′C′, we apply the translation rule to each vertex of ∆ABC:
Vertex A: (x, y) → (x - 3, y + 4)
(-3, 1) → (-3 - 3, 1 + 4) = (-6, 5)
So, vertex A of ∆A′B′C′ is located at (-6, 5).
Vertex B: (x, y) → (x - 3, y + 4)
(-3, 4) → (-3 - 3, 4 + 4) = (-6, 8)
So, vertex B of ∆A′B′C′ is located at (-6, 8).
Vertex C: (x, y) → (x - 3, y + 4)
(-7, 1) → (-7 - 3, 1 + 4) = (-10, 5)
So, vertex C of ∆A′B′C′ is located at (-10, 5).

AB=7.92,BC=5.76
Answers
In triangle ABC, the values of AB and BC are 9.68 and 7.04 respectively i.e. A.
What is a triangle's definition?
A triangle is a geometric form that has three straight sides and three angles. It is a fundamental geometric form that is frequently utilised in mathematics, science, and everyday life.
Triangles are distinguished by three sides and three angles. The sum of each triangle's three angles is always 180 degrees. Triangles are classified according to the length of their sides and the measurement of their angles.
Now,
As given ΔDEF ≈ΔABC
that means ratio of all sides will be equal
i.e. AB/DE=BC/EF=AC/DF
then AB/8.8=6.71/6.1
AB=1.1*8.8
AB=9.68
and BC/6.4=6.71/6.1
BC=1.1*6.4
BC=7.04
Hence,
the values of AB and BC are 9.68 and 7.04 respectively.

A graph of the image of ABC under a dilation whose center is P and scale factor is 1/2 is shown in the image below.
What is dilation?In Geometry, a dilation can be defined as a type of transformation which typically changes the size of a geometric shape, but not its shape.
In this exercise, we would use an online graphing calculator to plot the image of ABC after a dilation by a scale factor of 1/2 centered at P.
Based on the image (see attachment), we can logically deduce that each vertex is 1/2 times as far from center P as the original vertex and each segment is 1/2 times as long as the original:
Side length A'C' = 8.2/2 = 4.1
Side length A'B' = 5.7/2 = 2.85
Side length B'C' = 12.2/3 = 6.1

The problem can be translated into an equation as follows: 8x = (1/3)(x+2)
the answer that represents this situation is: 8x = (1/3)(x+2)
Simplifying the right side of the equation:
8x = (1/3)x + (2/3)
Multiplying both sides of the equation by 3 to eliminate the fraction:
24x = x + 2
Subtracting x from both sides of the equation:
23x = 2

x = 2/23

How to maximize the revenue?We know that the number of items sold for a prize p is:

Then the revenue will be:
R = (-2.35p + 470)*p
So we need to find the value of p that maximizes that quadratic equation, we can see that the maximum will be at the vertex, then let's write:
R = -2.35p² + 470p
The vertex is at:
p = -470/(2*2.35)

Answers
Thus, the obtained expression for the perimeter of the rectangle in centimeters is found as: P = 2(11v + 5w) cm.
Explain about the perimeter of the rectangle?The perimeter of a rectangle is the length measured around the edge of the rectangle. Although a rectangle has two dimensions, its perimeter only has one and is expressed in linear distances like feet or meters.
The perimeter calculation can be used, for instance, to calculate that many ft of brick border are required overall if somehow the rectangle depicts a garden which needs a brick border.
The sum of the lengths of a rectangle's four sides is known as its perimeter.
Rectangle perimeter = 2L + 2W.
Length = (6v+7w)
width = (5v - 2w)
P = 2 (length + width)
P = 2(6v+7w + 5v - 2w)
