A) A mark dwon greater than 99% and less than 100%

Mark down 99.1% of x

Original price: x

Final price: original price -  mark down = x - 0.991 x = 0.009x

=> If orginal price is 1000 and mark down is 99.1% , final price = 0.009*1000 = 9

You can check that the mark down is 99.1% of 1000 = 991.

b) A mark down that is less than 1%

Mark down: 0.1%

Original price: 10,000

Mark down: 10,000 * 0.1% = 10

Final price: 10,000 - 10 = 9,990

c) A mark up that is more than 200%

Mark up: 300%

Original price: 100

=> final price = 100 + 100*300% = 100 + 300 = 400

What is 31 billion in scientific notation? <br><br> explain clearly &lt;3 :D
MArishka [77]

Answer:

3.1*10^10

Step-by-step explanation:

31 billion would be written like that because... there are 9 0's left, and that goes up to 10 because i turned 31 to 3.1 not 31, so that value after a decimal point adds 1

A ball is thrown into the air with an initial velocity of 22 meters per second.
lbvjy [14]

Answer:

27.4 metres

Step-by-step explanation:

Um, your question is missing the x's. I'm going to assume, -4.9x^2+22x+5.5

= -4.9(3)^2+22(3)+5.5

= 27.4

At 3 seconds the ball is 27.4 metres above the ground.

Seven less than one-fourth of a number is 2. What is the number?
insens350 [35]

Based on the equation given, it can be deduced that the value of the number will be 36.

Let the number be represented by x

Therefore, seven less than one-fourth of a number will be:

=(1/4 × x) - 7

= 0.25x - 7

Now, seven less than one-fourth of a number is 2 will be written as:

0.25x - 7 = 2

0.25x = 2 + 7

0.25x = 9

x = 9/0.25

x = 36
