Answer:
Option A - 
Step-by-step explanation:
Given : Expression 
To find : Solve the expression ?
Solution :
Step 1 - Write the expression
Step 2 - Multiply the first two bracket in multiplication if base are same power get added and apply symbol rule of multiplication 
Step 3 - Again multiply the bracket,
Therefore, Option A is correct
3/5 = 0.6 = 60%
60% of the total take Spanish.
That leaves 40% for the other languages.
1/4 of 40% is 10% that take German.
40% - 10% = 30% take French.
Answer:
$19575
$20945.25
Step-by-step explanation:
The current price of the car is $43500 but if I wait for 18 months, then it will be 55% cheaper.
So, the after 18 months the price of the car will be 
dollars.
If sales tax is 7%, then the total price of the car after waiting for 18 months will be 
dollars. (Answer)
Answer
0.47qt a sec
Reason
Convert the gallons to quart using the formula “q=4g”
q=4(7)= 28
So we learn that it’s 28 quarts a minute. To figure it out by the second divide by 60.
28 divided by 60 equals 0.4667
Round to the nearest hundredth and it equals
0.47
There for it is 0.47 quarts a second.
Okay, so in order to find scientific notation you're going to either move the decimal place to the left or right in order to make your answer a number between 1 and 9. In this case you're going to need to move it right, because you need to make it bigger in order to make it a number between 1 and 9. You'll have to move the decimal 9 places to the right, which will give you the number 2. Since you are making the number bigger, your exponent will be negative. That happens anytime you move the decimal place to the right. To the left, your exponent will be positive. Therefore the answer to 1 is:
2.00X10^-9
As for number two, you must first start by using the area formula of a triangle. That equation would be
A= 1/2bh or A=bh/2 (b=base and h=height)
By plugging that in you get an area of 83,200 miles. As mentioned before, when finding scientific notation, you want a number between 1 and 9. To do so, we have to make this number smaller by moving the decimal 4 places to the left (making the exponent positive) and resulting in an answer of:
8.32X10^4 miles
