x=0

Step-by-step explanation:

Simplify the equation first:

-8x+14=-2(4x-7)

-8x+14=-8x-14

-8x+14+14=-8x-14+14

-8x+28=-8x

-8x+28+8x=-8x+8x

28=0

Un productor agricola tiene que envasar huevos en cajas de 12, de 6 o de 30. Si sabemos que tiene un numero parecido a 1000 huev

musickatia [10]

Answer:

El productor tiene que envasar 960 huevos.

Step-by-step explanation:

Es necesario determinar el mínimo común múltiplo de 6, 12 y 30. En primer lugar, se determina cada número como productos de números primos:

$6 = 2\times 3$

$12 = 2^{2}\times 3$

$30 = 2\times 3\times 5$

El mínimo común múltiplo es:

$M.C.M. = 2^{2}\times 3\times 5$

$M.C.M. = 60$

El número total de huevos próximo a 1000 unidades es un múltiplo del mínimo común múltiplo:

$n = 60\times 16$

$n = 960$

El productor tiene que envasar 960 huevos.

A rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeter

maksim [4K]

Answer:

25%.

Step-by-step explanation:

Let E be the event that the dart lands inside the triangle.

We have been given that a rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeters.

We know that probability of an event represents the chance that an event will happen.

$\text{Probability}=\frac{\text{Favorable no. of events}}{\text{Total number of possible outcomes}}$

$\text{Probability that dart lands inside the triangle}=\frac{\text{Area of triangle}}{\text{Area of rectangle}}$

$\text{Probability that dart lands inside the triangle}=\frac{162}{648}$

$\text{Probability that dart lands inside the triangle}=0.25$

Convert into percentage:

$0.25\times 100\%=25\%$

Therefore, the probability that dart lands inside the triangle is 25%.
