Answer:
h=7.5 in
Step-by-step explanation:
see the attached figure with letters to better understand the problem
In the right triangle ABC
sin(CAB)=15/18 ----> opposite side divided by the hypotenuse
In the right triangle CDE
sin(DCE)=h/9 ----> opposite side divided by the hypotenuse
In this problem
∠CAB=∠DCE ------> by corresponding angles
therefore
sin(CAB)=sin(DCE)
15/18=h/9
solve for h
h=15*9/18
h=7.5 in
Answer:
3/10 (see picture for work)
<h2>Correction:</h2>
- I meant to write down
, not
.
Simply add all of it together.
13+6=19
19+8=27
27+7=34
34 is the perimeter
The correct answer is B. Multiply input number by 4
Answer:
56 messages.
Step-by-step explanation:
So, from the $79 you subtract $45.37, which results in $33.63. That is the amount he has left for the text messages. So, you divide $33.63 by 0.60c, which results in 56.05. However, you cannot have a .05 of a text message, so it rounds to 56 messages.
