Is BC=2.3 one of the options?
For that question, you can use the cosine rule, where;
In this case, we have..
Solving for BC with this will get you 2.250406, rounded off to the tenth is 2.3.
Explanation:
Model: 1903
5 inches= 16 feet
wingspan=12.5 inches
In feet is the actual wingspan. Basically you set up an equation
Next you can cross multiply which is 5*y / 16*12.5 and get 5y=200
After you isolate y by dividing by 5 on both sides.
Y=40
Answer: The wingspan of the actual flyer is 40 feet.
Answer:
135=15m+25 OR 15m+25=135
Step-by-step explanation:
To set this equation up you want to look at key words. It states that "Karina now saved $135" in meaning her total saved. Now it states she STARTED the account with 25 so that would be added to the amount she adds per month (which is $15). The equation can be set up as 15m+25=135. 15m because m stands for every month she added $15, 25 because she started the account with 25 and 135 because that's her total after the several months.
