Un estanque tiene dos laves, una de las cuáles
que salen 117 litros en 8 minulos y un desagüe que por el que salen 42 litros en 6 minutos el estanque contenía 500 litros de agua y abriendo las dos llaves al mismo tiempo y el desagüe al mismo tiempo se acabo de llenar en 48 minutos
cuál es la capacidad del estanque
Answer:
8,688 litros.
Step-by-step explanation:
Dado que un estanque tiene dos llaves, de las cuáles salen 117 litros en 8 minutos y un desagüe que por el que salen 42 litros en 6 minutos, el estanque contenía 500 litros de agua y abriendo las dos llaves y el desagüe al mismo tiempo el estanque se acabó de llenar en 48 minutos, para determinar cuál es la capacidad del estanque se deben realizar los siguientes cálculos:
6 = 42
8 = X
8 x 42 / 6 = X
336 / 6 = X
56 = X
500 + 46 x (117 + 117 - 56) = X
500 + 46 x 178 = X
500 + 8,188 = X
8,688 = X
Así, la capacidad del estanque es de 8,688 litros.

Answer:
11. 78
12. 4x² - 3x - 1
Step-by-step explanation:
11. Sum of n whole numbers = ½(n² + n)
Multiply
½*n² + ½*n
= n²/2 + n/2
To find the sum of the first 12 whole number, substitute 12 for n into the equation.
= 12²/2 + 12/2
= 144/2 + 12/2
= 72 + 6
= 78
12. Area of trapezoid = ½(a + b)*h
Where,
a = 5x - 4
b = 3x + 2
h = x + 1
Area = ½(5x - 4 + 3x + 2)*(x + 1)
Area = ½(8x - 2)*(x + 1)
Area = ½[8x(x + 1) -2(x + 1)]
= ½[8x² + 8x - 2x - 2]
Add like terms
= ½(8x² - 6x - 2)
= ½(8x²) - ½(6x) - ½(2)
= 4x² - 3x - 1

Team A ships six times as many packages as Team B and one third as many as Team C. If Team C ships 287,450 packages, how many packages does Team B ship.
Answer:
95816.2222
Step-by-step explanation:
you divide 2874500 by 3
The number of packages that Team B ships is 15969
We make use of the following representations
[tex]A \to[/tex] Team A
[tex]B \to[/tex] Team B
[tex]C \to[/tex] Team C
From the first statement in the question
[tex]A = 6B[/tex] ---- 6 times as many as B
From the second statement
[tex]A =\frac{1}{3}C[/tex] ---1/3 as many as C
From the third
[tex]C = 287450[/tex] ---- packages by team C
To calculate the number of packages by team B,
Substitute [tex]C = 287450[/tex] in [tex]A =\frac{1}{3}C[/tex]
[tex]A = \frac{1}{3} * 287450[/tex]
[tex]A = \frac{287450}{3}[/tex]
Next, we calculate the number of packages by team A by substituting [tex]A = \frac{287450}{3}[/tex] in [tex]A = 6B[/tex]
[tex]\frac{287450}{3} =6B[/tex]
Make B the subject
[tex]B = \frac{287450}{3*6}[/tex]
[tex]B = \frac{287450}{18}[/tex]
[tex]B = 15969[/tex] -- approximated to the nearest whole number
