Answer:
Original number: 923076
Step-by-step explanation:
Original number = 9????? let's use x to represent ?????
Then the original number = 900000 + x
when 9 be moved to the end ?????9 i.e. 10x + 9
900000 + x = 4 * (10x + 9)
900000 + x = 40x + 36
39x = 899964
x = 23076
Original number: 923076
check: 230769 x 4 = 923076 .... correct
Answer:
(0,-8) and (2.6,0)
Step-by-step explanation:
according to desmos
15h > = 200
h > 200/15
h > 13 1/3.......1/3(60) = 60/3 = 20
13 hrs and 20 minutes is correct...nice job :)
Answer:
Area = 24.75 sqr units
Step-by-step explanation:
You will need these formulas:
Midpoint =
Area = b x h
Let us treat CD as the base. Find the length of the base with the distance formula. Use the coordinates for points C & D.
The base is .
The height is the distance between point E and the midpoint of line CD.
Midpoint of CD = = (, )
Use the distance formula to find the height.
Find the area with the two distances that were found.
Area =
Area =
Area = 24.75 sqr units
