When Bill Nye was first learning to type, he typed at a rate of 7.8 words per minute. How many words could he type in 4.7 minutes? I KNOW HOW TO DO THIS BUT CAN SOMEONE TELL ME IF IM SUPPOSED TO ROUND OR KEEP IT AT 36.66 CAUSE ITS WORDS

Since the question gives a one-place decimal for his rate, it will be appropriate to have a one-place decimal in your answer.

Step-by-step explanation:

It's about "significant digits" and since words consist of individual letters, it is possible to type a partial word.

b. hoped i'm right lol

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
