1.8, 2.85, 3.90, 4.95, 6
To find the rule for this sequence, you find the difference between 2 numbers ..
1.8 + n = 2.85
n = 1.05
2.85 + n = 3.90
n = 1.05
3.90 + n = 4.95
n = 1.05
4.95 + n = 6
n = 1.05
As you can see, each have a difference of +1.05
The rule for this sequence is adding 1.05
Answer:
area of rectangle = 120 cm²
area of triangle = 24 cm²
area of trapezoid = 144 cm²
Step-by-step explanation:
12 * 10 = 120
12 * 4 = 48
48 / 2
add the triangle and rectangle area together
60/15=4, 14*4= 56 BPM. 1512/56= 27 min
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
.
