Answers
Answer:
The answer is:
Step-by-step explanation:
In order to determine the answer, we have to know about scientific notation.
In general the scientific notation is:
where:
a= rational number such that its absolute value has to satisfy:
b= the power of 10 required so that the scientific notation is mathematically equivalent to the original number.
We have to follow the next steps to determine the scientific notation of any number:
- Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is "a".
- Count how many places you moved the decimal point. This number is "b".
- If you moved the decimal to the left, "b" is positive. If you moved the decimal to the right, "b" is negative. If you did not need to move the decimal, "b" = 0.
- Remove trailing 0's only if they were originally to the left of the decimal point.
Finally, the number 0.000000028 written in scientific notation is:

140% of 35 is 25
x = 25
35= 100%
we know, that x is 140% of the output value, so we can write it down as↓
x= 140% which leads use to 2 simple equations now
35= 100%
x= 140%
where left side of both of them have the same units so, we can do something likee that ↓
35/x= 100%/140% now we have to solve the equation
35/x= 100/140
(35/x)·x= (100/140)·x
multiply both sides of the equation by x
35= 0.714285714286·x
divide both sides of the equation by
(0.714285714286) to get x
35/0.714285714286= x
which would be
49= x
x= 49
now we are here - 140% of 35= 49, THERE's YOUR ANSWER IK ITS LENGTHY BUT THATS ALL THE STEPS TO HELP U . HAVE GREAT DAY

$30 x .05 = $1.5
Take $1.5 off of the $30.
After discount, the price was $28.5.
Sales price needs to be added.
$28.5 x .05 = $1.4
$28.5 + $1.4 = $29.9
$29.9 is the final price of the wind chime.
Answer: 29.9
How to solve this problem
5%=.05
$30 x .05 = $1.5
Take $1.5 off of the $30.
After discount, the price was $28.5. Sales price needs to be added.
$28.5 x .05 = $1.4
$28.5 + $1.4 = $29.9
$29.9 is the final price of the wind chime.

3/8=9/24
2/3=16/24
Now add them together.
9/24+16/24=25/24
Next add the second two fractions 9/24 and 16/24.
9/24+16/24=25/24
Since all fractions equal 25/24, the equation was true!
Hope this helps!
