Jerónimo ha fabricado pequeñas pelotas típicas como la que se muestra en la figura 1 (en mi libro aparecen cuatro pelotas). Para cada pelota se emplean 216 centímetros cuadrados de tela típica determina el radio de la pelota y aproxima su valor al decimal cercano.
Expresión r = área superficial / 4 * pi elevado al cubo, permite determinar el radio de cada pelota. Les pido ayuda con esta tarea
Answers
Answer:
r = 4,2 cm
Step-by-step explanation:
El área de una pelota es la siguiente:
[tex] A = 4\pi r^{2} [/tex] (1)
En donde:
A: es el área superficial = 216 cm²
r: es el radio =?
Resolviendo la ecuación (1) para r podemos determinar el radio de cada pelota:
[tex] r = \sqrt{\frac{A}{4\pi}} = \sqrt{\frac{216 cm^{2}}{4\pi}} = 4,2 cm [/tex]
Por lo tanto, el radio de cada pelota es de 4,2 cm.

Find the coordinates of the missing endpoint if B is the midpoint of AC.
C(5/3,-6),B(8/3,4)
Answers
Given :
[tex]C(\dfrac{5}{3},-6)\ , \ B(\dfrac{8}{3},4)[/tex] .
B is the mid-point of AC .
To Find :
The missing endpoint if B is the midpoint of AC.
Solution :
Let , coordinate of point A is ( h, k) .
So , mid-point B is given by :
[tex](\dfrac{\dfrac{5}{3}+h}{2},\dfrac{-6+k}{2})[/tex]
Comparing above point with [tex]B(\dfrac{8}{3},4)[/tex] , we get :
[tex]\dfrac{\dfrac{5}{3}+h}{2}=\dfrac{8}{3}\\\\h+\dfrac{5}{3}=\dfrac{16}{3}\\\\h=\dfrac{11}{3}[/tex] [tex]\dfrac{-6+k}{2}=4\\\\k=14[/tex]
Therefore , the value of point A is [tex](\dfrac{11}{3},14)[/tex] .
Hence , this is the required solution .

A rectangular garden is surrounded by a path of uniform width 3m. If breadth of the garden is 40m and area of the path is 588m², find the length of the garden.
Answers
Answer:
52 m
Step-by-step explanation:
Width of the path = 3 mBreadth of the garden = 40 mLength of the garden = xArea of the path = 588 m²Area of the path is the difference of the of full area and the area of the garden.
Full area will have the sides:
40 + 3*2= 46 and x + 3*2 = x + 6Area of the garden is
40*xSo the difference is:
588 = (x + 6)*46 - 40*x588 = 46x + 6*46 - 40x588 = 6x + 2766x = 588 - 2766x = 312x = 312/6x = 52 mThe length of the garden is 52 m
The length of a rectangle is three more than twice the width. The perimeter is 96. What are the dimensions?
Answers
Answer:
Width =15
Length =33
Step-by-step explanation:
Take width as x
And length as 2x+3
Perimeter as 96
Formula of the perimeter of a rectangle is 2l+2w
X+×+2×+3+2×+3=96
6x+6=96
6x=96-6
6×=90
X=15
Width =x and x =15 so width =15 while length =33

There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716. Find the number of orchestra seats and the number of balcony seats sold for the performance.
Answers
x = # of balcony seats
y = # of orchestra seats
We have to create a system of equations to solve this problem
x + y = 256
$8x + $12y = $2,716
We will solve this system of equations by elimination.
Multiply the first equation by -8
-8x - 8y = -2048
8x + 12y = 2716
Let's add the equations together
0 + 4y = 668
Simplify the left side
4y = 668
Divide both sides by 4
y = 167
We can subtract 167 from 257 to get the number of balcony seats.
257 - 167 = 90 balcony seats
There are 167 orchestra seats and 90 balcony seats
The number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716.
Let x be the number of Orchestra seats and y be the number of balcony seats. Then the equation will be
x + y = 257 ...1
12x + 8y = 2716 ....2
From equations 1 and 2, then we have
12x + 8(257 - x) = 2716
4x = 660
x = 165
Then the value of the variable y will be
165 + y = 257
y = 92
Thus, the number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
