Answer:
384 and a half.
Step-by-step explanation:
Took me a while, but just add 48 for every 2 minutes.
Perimetr=4*side, so we know perimetr =64mm
so 4*side=64mm
side=64/4mm
side=16mm
Answer: side is 16 mm
Answer:
The door is 7 feet x 3 feet
Step-by-step explanation:
<em>AREA:</em> 7 x 3 = 21
<em>PERIMITER:</em> 7 + 7 + 3 + 3 = 20
If two line crosses, then the vertical angles are the angles opposite each other. In this way, these angles share the same vertex. So, the vertical angles are always equal. Therefore, in this problem, the right answers are:
1. ABE and CBD
Notice that the vertex is B, so these two angles share the same vertex. Accordingly, these two angles are vertical angles.
2. ABC and EBD
The same reasoning is applied here. The vertex is also B. Notice that <em>the angles CBD and ABD add up to 180 degrees. </em>
Now, a whole, will be 15/15 or 1 whole.
now, the sprinkler does 1/15 of the lawn in 1/3 of an hour, how long will it be to do the whole 15/15?
