Total volume = 3 litres
Volume of each glass = 1/4 litre
Divide 3 by 1/4
3 / (1/4)
3* (4/1)
= 12 glasses
The triangle has a base of 7 so 1/2 the base is 3.5.
The height = 7.5 (from graphic)
Area of "left triangle" = 3.5*7.5 / 2 =
<span>
<span>
<span>
13.125
</span>
</span>
</span>
The entire triangle area = 2 * 13.125 =
26.25
Triangle perimeter both legs = 16.6 + base (7) = 23.6
Answer:
-2 ≤ x ≤ 14
Step-by-step explanation:
x - 6 + 7 ≥ -1
x + 1 ≥ -1
x ≥ -2
-(x - 6) + 7 ≥ -1
-x + 6 + 7 ≥ -1
-x + 13 ≥ -1
-x ≥ -14
x ≤ 14
