There is a cereal box and the dimensions are 10 inches tall, 3 inches wide and 7 inches long. If you were to fill the box with c

JulsSmile [24]

Answer:

$6.30

Step-by-step explanation:

First, get the volume of the cereal box with the equation V = lwh.

V = 7(3)(10) = 210 cubic inches

Since it costs $.03 per cubic inch, multiply this cost by the volume to get the total cost to fill the box.

.03(210) = $6.30

Company XYZ has 97 employees. 31 Of the employees are vegetarian, 36 of the employees owns a Nissan Leaf and 6 of the employees

FrozenT [24]

Answer: $\dfrac{61}{97}$

Step-by-step explanation:

Let V = Event of selecting vegetarian employee

N = Event of selecting employee who owns a Nissan Leaf.

Given: Total employees = 97

n(V) = 31

n(N) = 36

n(N and V) = 6

By formula,

n(N or V) = n(V) + n(V) - n(N and V)

= 31+36-6

=61

By probability formula,

$P(N \ or \ V)=\dfrac{n(N\ or\ V)}{Total }\\\\=\dfrac{61}{97}$

Hence, the probability that the employee is vegetarian or that she/he owns a Nissan Leaf = $\dfrac{61}{97}$

2x+3y=4

garri49 [273]

Answer:

Option D.

Step-by-step explanation:

we have

$2x+3y=4$ -----> equation A

$2x-5y=-12$ -----> equation B

Solve the system by elimination

Multiply both sides equation A by -1

$-1(2x+3y)=-1(4)$

$-2x-3y=-4$ -----> equation C

Adds equation C and equation B

$-2x-3y=-4\\2x-5y=-12\\------\\-3y-5y=-4-12\\-8y=-16\\y=2$

<em>Find the value of x</em>

substitute the value of y in either equation

$2x+3(2)=4\\2x+6=4\\2x=-2\\x=-1$

The solution is the point (-1,2)

In this problem Option A,B and C are correct

The option D not result in a system with a pair of opposite terms

because

Multiply both sides of equation B by -3

$-3(2x-5y)=-3(-12)$

$-6x+15y=36$ -----> equation C

Multiply both sides of equation A by 5 $5(2x+3y)=5(4)$

$10x+15y=20$ ----> equation D

equation C and equation D not have a pair of opposite terms
