Latoya, Henry, and Manuel served a total of 112 orders Monday at the school cafeteria. Latoya served 7 more orders than Henry. M

Anarel [89]

Answer:

Henry: 21

Latoya: 28

Manuel = 63

Step-by-step explanation:

x = orders henry served

x + 7 = orders latoya served

3x = orders manuel served

x + (x + 7) + 3x = 112

5x + 7 = 112

5x = 105

x = 21

x + 7 = 21 + 7 = 28

3x = 3 * 21 = 63

A certain system has two components. There are 6 different models of the first component and 10 different models of the second.

Alisiya [41]

Answer: 1800

Step-by-step explanation:

Given : A certain system has two components.

Number of different models of the first component = 6

Number of different models of the second component = 10

A salesman must select 2 of the first component and 3 of the second to take on a sales call , so we use combinations ( ∵ order of selection not matters)

The number of different sets of components can the salesman take = $^{6}C_2\times^{10}C_3$

$\dfrac{6!}{2!(6-2)!}\times\dfrac{10!}{3!(10-3)!}\ \ [\because\ ^nC_r=\dfrac{n!}{r!(n-r)!}]$

$=1800$

Hence, the number of different sets of components can the salesman take = 1800
