Answer:

2.178 × 10^6

Step-by-step explanation:

Multiply 4840 × 450 to get 2,178,000

Move the decimal 6 places left then multiply by 10 to the 6th power, the number of places the decimal moved, to put it into scientific notation form. Scientific notation always has only one digit to the left of the decimal point.

PLEASE HELP ME!!!

<h3>Answer:  15 years old</h3>

=============================================

Explanation:

m = Maggie's age (some positive whole number)

4m = four times her age

4m-7 = seven years younger than 4m = brother's age

Add up her age (m) and her brother's age (4m-7) to get a sum of 68.

m+(4m-7) = 68

5m-7 = 68

5m = 68+7

5m = 75

m = 75/5

m = 15

Maggie is currently 15 years old.

Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.

Their current year ages add to: 15+53 = 68 which confirms the answer.

Find the selling price of a $270 bicycle with a 24% markup.
lisov135 [29]
1 percent of $270 is 2.70 (you just move the decimal point). then multiply your 1 percent by 24 and you have the answer. I get $64.80, doing it on paper.
Add the 24 percent to the original price and you have your retail price: $334.80.  If you have a calculator, check my maths.
