Answer:
The distance from hot air balloon to the ground
.
Step-by-step explanation:
Labelled diagram of given scenario is shown below.
Given that,
An angle of elevation of Hot air balloon by Angie is
°.
When she stepped back
then angle of elevation was
°.
Height of Angie is
.
To find: How far off the ground is a hot air balloon.
So, from figure
Height of Angie 
In triangle Δ
,
⇒ 
⇒
....................(1)
Now, In triangle Δ
⇒ 
⇒ 
Here, substituting the value
from Equation (1) we get,


⇒
⇒ 
⇒
Now, finding the value of
from equation (1)

Therefore Length of
= 
.
Hence,
The distance from hot air balloon to the ground
.
I think the answer is 320miles,
3hs at 60mph = 180miles
2hs at 70mph = 140miles
so 180+140=320miles
The answer is B :DD
that one doesnt make sense
The answer is -5 hope this works
Answer:
$25.5
Step-by-step explanation:
Sure, so the total of the
Item:
30 Dollars ($)
and the discount price is
15 percent (%)
So 30 times 0.15 because 30 is the price in total and 0.15 is the percentage but in a decimal form.
30 times 0.15 equals 4.5
4.5 is the amount that 15 % equals.
30 minus (-) 4.5 because once again the total is 30 and since we have a discount price then we minus (-) the discount price by the total and you get
A total with the discount price as 25.5 Dollars or $25.5
Hope this helps ;)
