Curtis sees a maple tree and a pine tree in the forest. He knows that the pine tree is 20.68 feet tall. On a sunny day, the shadow of the pine is 4.2 feet long while the maple's shadow is 20.02 feet long. Estimate the height of the maple tree.
Answer:
The height of the maple is 98.6 feet
Step-by-step explanation:
Similar Triangles
The triangles formed by each tree's height, their shadow, and the projection of their shadow in the ground are right and similar triangles since the sun has the same elevation at the same time in the same place. It's shown in the image attached.
Curtis sees a maple tree of unknown height Hm and a pine tree of height Hp=20.68 feet. He also measures the projection of the shadow of the pine of Xp=4.2 feet and the same measure of the maple of Xm=20.02 feet.
Since both triangles are similar, the proportion between their sides is equal, thus:
[tex]\displaystyle \frac{Hm}{Hp}=\frac{Xm}{Xp}[/tex]
Solving for Hm:
[tex]\displaystyle Hm=\frac{Xm*Hp}{Xp}[/tex]
[tex]\displaystyle Hm=\frac{20.02*20.68}{4.2}[/tex]
Hm = 98.6 feet
The height of the maple is 98.6 feet

Step-by-step explanation:
Se ha decidido repoblar con 150 000 árboles una zona asolada por un incencio. Se quieren plantar los árboles formando un cuadrado con el mismo número de árboles y la misma separación entre ellos. ¿Cuántos árboles se podrán plantar para formar el cuadrado más grande posible?
Responder :
Se plantarán 149769 árboles
Explicación paso a paso:
Dado que:
Número de árboles a plantar = 150.000
Los árboles deben disponerse para formar un cuadrado;
La cantidad de árboles que se pueden plantar para hacer el cuadrado más grande posible:
Área de un cuadrado = s²
Dónde; s = Longitud de cualquier lado; ya que todos los lados son iguales.
El mayor número de árboles que se pueden plantar es el cuadrado perfecto más alto hasta 150.000.
Esto se puede obtener tomando la raíz cuadrada de 150000
Cuadrado (150.000)
= 387,29833
El cuadrado del número entero da el valor cuadrado perfecto más alto antes de 150 000
Por lo tanto,
s = 387 =; 387
Cantidad total de árboles; s² = 387² = 149769

solve for X
The sum of the inside angles of a 6 sides figure is 720
Add the known angles together:
90 + 112 + 131 + 154 + 118 = 605
Subtract the sum of the known angles from 720 for x:
x = 720 - 605 = 115
x = 115 degrees.
Answer:
The sum of the interior angles of the hexagon is 720°
[tex]x + 154 + 131 + 112 + 90 + 118 = 720 \\ x + 605 = 720 \\ x = 720 - 605 \\ \boxed{x = 115}[/tex]

Answer: 57
Step-by-step explanation: The shorter segment of the lines that cross the centroid are always half of the longer segment. This means segment QM equals 19, since it is half of 38. When 38, and 19 are added together, it equals 57.

Ashlynn played six rounds of golf. Her scores were 72, 79, 74, 76, 76, and 75. She really wants to have a mean of 75 after her next round of golf. What must she shoot in order to have a mean of 75?
72
75
66
73
Answer:
73
Step-by-step explanation:
Set up as if you're finding the average: total the 6 scores and add 'x', then divide by 7 and set this equal to 75
'x' = score she must meet or exceed to achieve an average of 75
452 + x = 75
7
cross-multiply: 452 + x = 75(7)
452 + x = 525
x = 73

Which statement is true when comparing how a student would complete the solution for the linear equation -2x + 3 = 6 to how the student would complete the solution for the linear inequality -2x + 3 < 6?
Completing the solution for the equation is the same as completing the solution for the inequality. The student would divide both sides by -2 in either case.
Completing the solution for the equation is the same as completing the solution for the inequality. The student would divide both sides by -2 in either case.
Completing the solution for the equation is the same as completing the solution for the inequality. The student would multiply both sides by -2 in either case.
Completing the solution for the equation is the same as completing the solution for the inequality. The student would multiply both sides by -2 in either case.
Completing the solution for the equation is not the same as completing the solution for the inequality. The student would divide by -2 to complete the solution for the equation and would divide by -2 and change the less than sign for the inequality to greater than.

Answer:
1st year: 100-5=95
36000/100 X 95 = 34200
2nd year: 100 + 10 = 110
34200/100 X 110 = 37620
3rd year 100 + 12.5 = 112.5
37620/100 X 112.5 = 42322.50
