Answer: 35% decrease
Step-by-step explanation: In this problem, we're asked to find the percent decrease if the price of an item changes from $180 to $117.
To find the percent decrease, we use the following formula.
The <em>amount of change</em> is the difference between the two numbers which in this case is 180 - 117 and the <em>original number</em> is the first number which is 180.
The difference between 180 and 117 is 63 and we put that over 180.
Now we have .
Now, we either use a calculator or long division. I will use my calculator but if you don't have access to one, long division is always available.
63 ÷ 180 = 0.35
Now since we want to find the percent increase, we need to change 0.35 to a percent and we can do this by moving the decimal point two places to the right.
0.35 ⇒ 35%
So when the price changes from $180 to $117, it is decreased by 35%.
<span>6.5 x 10^6
To answer this question, you need to divide the mass of the sun by the mass of mercury. So
2.13525 x 10^30 / 3.285 x 10^23 = ?
To do the division, divide the mantissas in the normal fashion
2.13525 / 3.285 = 0.65
And subtract the exponents.
30 - 23 = 7
So you get
0.65 x 10^7
Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving
6.5 x 10^6
So the sun is 6.5 x 10^6 times as massive as mercury.</span>
10xas much as 60? I'm confused at what u mean please explain
To find volume you use the formula
Volume=base× height
the base is 6×5
he height is 11
Volume=(5×6)×11
Volume=30×11
Volume=330 cubic centimeters
