There are about 30.2 million small businesses in the u.s and about 30,000 other larger businesses. What percent of all businesse

Leni [432]

<h3>Answer:</h3>

99.90%

<h3>Step-by-step explanation:</h3>

STEPS:

Find the total amount
Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
Turn into a percentage by multiplying by 100

Find the total sum

30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total

Find the fraction that small businesses make up of the total

$\frac{small~businesses}{total~businesses} = \frac{30,200,000}{30,230,000} = 0.9990$

Convert to percentage

0.9990 → % = 0.9990 × 100 = 99.90%

Hope this helps,

Five friends have access to a chat room. Is it possible to determine who is chattingif the following information is known? Eithe

fenix001 [56]

Answer:

Kevin and Vijay are chatting

Step-by-step explanation:

Consider: Kevin=k

Heather=h

Randyor=v

Vijay=v

Abby=a

The values or the variables can be =o if they are not chatting and =1 if they arre chatting, then:

k+h>=1

v+r=1

a=r

v=k

if h=1 then a=1 and k=1, then as a=r, r=1 and as v=k, v=1, but then v+r=2, which is not possible because v+r=, then we can fisrt conclude than h=0.

.As k+h>=1, and h=0, then k=1. As k=v, then v=1.

As v+r=1, and v=1, then r=0. As r=a, a=0

So in conclusion, a=0, r=0, v=1, k=1 and h=0, so Kevin and Vijay are chatting

ADDITION METHOD

The whole problem with solving a system of equations is that you cannot solve an equation that has two unknowns in it. You need an equation with only one variable so that you can isolate the variable on one side of the equation. Both methods that we will look at are techniques for eliminating one of the variables to give you an equation in just one unknown, which you can then solve by the usual methods.
The first method of solving systems of linear equations is the addition method, in which the two equations are added together to eliminate one of the variables.
Adding the equations means that we add the left sides of the two equations together, and we add the right sides together. This is legal because of the Addition Principle, which says that we can add the same amount to both sides of an equation. Since the left and right sides of any equation are equal to each other, we are indeed adding the same amount to both sides of an equation.

You buy a storage case that holds 170 collectible die-cast cars. You have 137 die-cast cars. Write an inequality that describes

Murljashka [212]

Answer:

137 + x <= 170

Step-by-step explanation:

The following inequality will describe this scenario.

137 + x <= 170

the variable x in this scenario represents the total number of cars that you will purchase. This number is added to the number of toy cars that you already own which is 137. As long as this sum is less than or equal to 170 then your storage case will hold them.
