Answer:
49.2 feet
Step-by-step explanation:
x=73/Tan56=49.2391=49.2
|3k-2|=2|k+2l
Do Distributive Property and take 2 times by everything in the parenthesis. That will leave you with |3k-2|=2k+4. Then add like terms. 3k+2k=5k. Then -2+4=2. So you end up with 5k+2. I believe I'm right. If not please tell me.
Answer:
You bought 5 erasers.
Step-by-step explanation:
You have the erasers sold for 4 dollars each and you have only 20 dollars left over to buy erasers so you divide 20 by 4 to get 5
There are 100 centimeters in 1 meter. So to start with you must multiply 10000 by 100 to determine the number of centimeters in each race. This answer will be 1000000. Then to determine the number of centimeters in fifty races, you must multiply 1000000 by 50. This answer is 50000000. Then you must put it in scientific notation.
To do this you must move the decimal place over to the left until there is only one, nonzero number in front of it. Because you will move it to the left, your exponent will be positive. Therefore, your answer will be B.
There is no different in both of them. if you used both of them in a math problem you would still get the same answer as if you use the other one.
