You can write it with a double barred R.
Answer:
AB = 20 tan55°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan55° =
=
=
( multiply both sides by 20 )
20 tan55° = AB
A dot above 7, 4, 10, 2, and 20. Draw a box around the median, first quartile, and and the third quartile. Then connect the box to the minimum and maximum by drawing a line. Should look like this:
1L=1000mL
2800 mL=2.8L
If she needs 3.5 L, she currently has 2.8L,
so 3.5-2.8=0.7 L more or .7x1000=700 more mL
