We have that
2r−9≤−6------> 2r ≤ -6+9-------> 2r ≤ 3-----> r ≤ 1.5
the solution is the interval (-∞, 1.5]
using a graph tool
see the attached figure
Answer:
140
Step-by-step explanation:
5%/100 = 7/?
7 times 100 = 700
700 divided by 5 = 140 coins

Solving triangles</h3>
Based on the information given, it should be noted that the sine formula will be used.
Therefore, the equation to solve the question will be:
Sin 16° = x/3.5
x = Sin 16° × 3.5
x = 0.2756 × 3.5
x = 0.9646
