What is 300 in scientific notation
elena55 [62]
Hey there! 

The answer would most likely be: 3 × 10^2

Because, 10^2 = 100 and the problem becomes: 3 × 100 ← that gives you 300

Good luck on your assignment and enjoy your day!

Which polynomial is 4x+3 a factor
Lilit [14]
 <span>B. 
First look to simplify: 
(40x^2 + 22x - 6) = (2)(20x^2 + 11x - 3) 

now factor knowing one side must be (4x + 3) 
(2)(20x^2 + 11x - 3) = 
(2)(4x + 3)("SomethingX" + "something") 

4x times SomethingX must = 20x^2 
Something must be 5 (4x * 5x = 20x^2) 

now we know: 
(2)(20x^2 + 11x - 3) = 
(2)(4x + 3)(5X + "something") 

3 times "something" must equal -3 
that must be -1... therefore: 
(2)(20x^2 + 11x - 3) = 
(2)(4x + 3)(5X + -3) 

The fact that this works and the others don't means the answer is B.</span>

Which inequality models this problem? Miranda started a car-washing business. She spent $75 to purchase supplies to get started
ycow [4]

Given

Miranda started a car-washing business

She spent $75 to purchase supplies to get started and she uses about $0.50 worth of supplies per car washed.

Miranda charges $9 for each car washed

Find out the minimum number of cars Miranda will need to wash to make a profit.

To proof

As given

let c represent the number of cars.

She spent to purchase supplies to get started = $ 75

she uses worth of supplies per car washed = $ 0.50

Miranda charges  for each car washed = $ 9

than the inequality be

9c> 75+0.50c\\9c-0.50c>75\\8.5c> 75\\c> 8.8

i.e the minimum number of cars  Miranda will need to wash to make a profit is 9 .

Hence proved
