Answer:
The door should be 1.6cm wide on the drawing.
Step-by-step explanation:
1 meter is 100 centimeters.
Elena's bedroom door is 80 centimeters wide.
To find how wide it should be on the drawing, divide by 50.
= 1.6cm
The door should be 1.6cm wide on the drawing.
Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box =
ft
Height of the box = 2 ft
Volume of the box = length × width × height

= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube =
ft
Volume of the cube = length × length × length

Volume of the cube = 0.125 ft³

= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.
The first leg of the graph represents Manuel riding his bike for 3 units of time going 5 units distance gradually increasing his speed. The second line segment represents Manuel staying where he his for 4 1/2 units of time. The third represents Manuel going a fast speed back to where he started. I think.
Or the first is him going that distance picking up speed, the second him going a constant speed, and the third him slowing down/speeding up.
Well I know this is not linear becuase then the y-values would be going up by a constant number. So, B and C are gone. Personally, A looks a bid odd. So, If I were you I'd go with D.
Just my opinion, not 100%
