Alexa has finished her culinary training program and is now working full-time as a chef in a hotel resort restaurant. She has tr
otez555 [7]

Answer: The budget of Alexa is increased by $100.

Explanation:

It is given that the current income of Alexa is 3 times of her previous income.

Her previous salary was $800 and current salary was $2400.

Expenses =   Rent  + Utilities  + Groceries  + Savings  + Bus

The sum of previous expenses is,

Previous expenses = $300 + $60 + $200 + $100 + $30 = $690

The sum of current expenses is,

Current expenses = $300 + $60 + $250 + $150+ $30 = $790

Effect of income on expenses is the difference of current expenses and previous expenses.

Effect of income on expenses = $790 - $690 = $100

Therefore, the budget of Alexa is increased by $100.

Which expression is equivalent to 4√⋅3√⋅5√ ?
likoan [24]

Answer:

2\sqrt{15}

Step-by-step explanation:

To multiply radicals with the same root, you just need to multiply the numbers or expressions inside the root retaining the same root and then simplify the result.

In this case: \sqrt{3} \sqrt{4} \sqrt{5} = \sqrt{60} = 2\sqrt{15}

David has 3 1/2 cups of blueberries. He uses 1/4 of a cup of blueberries to make a breakfast smoothie. He uses 1/2 of the remain
dusya [7]

Answer:

1\frac{5}{8} cup of blueberries

Step-by-step explanation:

Since David starts out with 3 1/2 cups of blueberries and uses 1/4 cup to make a smoothie, we will need to subtract 1/4 from his starting amount of 3 1/2

  • 3\frac{1}{2}-\frac{1}{4}  =3\frac{1}{4} David now has 3 1/4 cup of blueberries

David then uses half of this new amount of blueberries to make his pancakes. We will need to divide by 2 in order to figure out how much half is

  • First we can turn 3 1/4 into an improper fraction to make it easier to work with → 3 1/4 = 13/4
  • Now dividing 13/4 by 2 gives us \frac{\frac{13}{4} }{2} =(\frac{13}{4})(\frac{1}{2}) = \frac{13}{8}
  • David used 13/8 cups of blueberries to make his pancakes
  • Turning this back into a mixed number leaves him with 1 5/8 cup of blueberries
