Answer:
Step-by-step explanation:
If you are rounding to nearest tenth
2.6 1.9
Nearest hundredth
2.6 1.87
If the number to the right of the one you want to round is 5 or above, you go up a number. If it's below, you go down 1.
Hope this helps.
Plug all the point into your calculator. Not sure if you need it y=mx+b but the R for that is r= -1
Answer: 12 hours
Step-by-step explanation:
Given : Working together, it takes Sam, Jenna, and Francisco two hours to paint one room.
When Sam works alone, he can paint one room in 6 hours. When Jenna works alone, she can paint one room in 4 hours.
Let 't' be the time taken by Francisco to paint one room on his own.
Then , we have
Rate of work of Sam +Rate of work of Jenna + Rate of work of Francisco =Rate of work they all do together

i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. t= 12
Hence, Francisco would take 12 hours to paint one room on his own.
<u>y = 3x - 2</u>
-- The ' 3 ' is the slope. If you double it to ' 6 ', the line is steeper.
-- The ' -2 ' is the y-intercept. If you double it to ' -4 ', the line crosses the y-axis lower.
Choice <u>(a)</u> says that . . . "... steeper, and lower y-intercept".
Answer:
7 miles per hour
Step-by-step explanation:
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
Hope this helps :)
