Answer:
64
Step-by-step explanation:
He will run 30 laps in 60 minutes because 10 times 3 and so if you divide 20 by 10 then he runs one lap in 2 minutes so 2 times 32 is 64 so it will take him that long
$210.67 is the answer. Rounded, of course, from 210.666666667
Answer:
400
Step-by-step explanation:
429 is closest to 400 on the number line so it would be 400
Answer: -112
Step-by-step explanation:
Given: Rate of lost money on an investment = $4 per day.
Since 1 week = 7 days
So, Amount of money she lost in 1 weeks = $ 4 x 7 = $28
⇒ Amount of money she lost in 4 weeks = $ 28 x 4 = $112
Since in integers, a loss is represented by negative integer.
So, Mrs. Rockwell lost $112 after 4 weeks which is represented by "-112" integers.
Answer: 97 degrees
Step-by-step explanation:
I drew some letters on your attachment to make it easier for you to understand.
To find angle y you need to find angle x first, you do that by doing (180=A+B+C) and you solve for A which is x degrees (A=180-B-C)
When you use angle C you must combine the 26 degrees and 55 degrees because if you use only 55 let's say, that would be the angle for triangle CDB, and we need C for triangle ABC.
So: A=180-42-81 -> A=57 degrees
Now you know Angle A (57 degrees) and Angle ACD (26 degrees)
All you have to do to find Y is to do: y=180-x-26
So y would be: 97 degrees
Keep in mind this is one of two solution methods I can see, if you want me to show you the other one as well just tell me in the comments, you are welcome.
