Answer:
DF,DE,EF
Step-by-step explanation:
Each piece should be 4.2 feet
the whole rope is 21 feet long and you divide it by 5 because you want 5 equal pieces.
21/5 (21 divided by 5) equals 4.2 feet
Answer:
center: (-10,-4)
radius: 9
Step-by-step explanation:
Let's start off by moving the 35 to the other side and grouping the x and y terms we have
(x²+20x)+(y²+8y)= -35
Next we take the term with the x coeficcent, divide it by 2, and square it
so
for the x we would do (20/2)²=100
and make sure we add that to the 35
(x²+20x+100)+(y²+8y+16)= -35+100+16
next factor everythign to get
(x+10)²+(y+4)²=81
therefore the center is (-10,-4)
and the radius is √81 or 9
Look in the table at the column that has 1 minute and 4.25 pages. Printer A prints 4.25 pages in 1 minute which is a rate of 4.25 pages per minute. The rate of printing is the slope in the equation. A rate of 4.25 pages per minute is represented by the equation y = 4.25x, where 4.25 ids the slope of the equation.
We are told that Printer A prints faster than Printer B, so Printer B must have a lower rate of printing than Printer A. The equation for Printer B must have a slope less than 4.25.
There are two choices which have a slope less than than 4.25.
Answer: y = 4.2x; y = 4x
Answer:
76 minutes
Step-by-step explanation:
The computation is shown below:
Since mark would take 1 hour and 15 minutes i.e. 60 + 15 = 75 minutes
And, emily takes for a minute = 1 minute
So, the number of minutes taken by Mars to drive is
= 75 + 1
= 76 minutes
