Answer:
P(water)=11/22=1/2
Step-by-step explanation:
The number of bottles with water is 11
The total number of bottles is 11 +9+2=22
Sothe probability that Ronald chooses a bottle of water is
P(water) =N(water)/N(total)=11/22=1/2
Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
The postulate that is used in order to prove the congruency of the triangles is the ASA which means (Angle – Side – Angle). The property that is applicable for the congruency of DB to itself is the reflexive property. Therefore, the answer to this item is the second choice.
Hope I helped! :)
Answer:
<u>Michelle has 17 pencils</u>
Step-by-step explanation:
Number of pencils Leslie has = 8 (She has 9 fewer pencils than Michelle)
Number of pencils Michelle has = 9 more than Leslie
How many pencils does Michelle have?
If Leslie has 8 and she has 9 fewer than Michelle, then:
Michelle has 9 more than Leslie
<u>Michelle has 9 + 8 = 17 pencils</u>
