42 times 2 because 84 divided by 24 equals 2. Also, 84 divided by 2 equals 24.
I believe it is that you multiply
In fact, both Amanda's and Stephen's profs are correct; they are just using different supplementary angles. Amanda's is using the supplementary angles <span>∠1 and ∠4, and</span> ∠3 and ∠4, whereas Stephen is using ∠1 and ∠2, and <span>∠2 and ∠3.</span><span> </span>Please check the picture to visualize this more effectively.
Answer:
Option D) 64
Step-by-step explanation:
see the attached figure with letters to better understand the problem
<em>In the right triangle BCD find BC</em>
Applying the Pythagoras Theorem

<em>In the right triangle ABC</em>

substitute the values
-------> equation A
<em>In the right triangle BDC</em>

substitute the values
-------> equation B
equate equation A and equation B

we are given
initial amount =1800
so,
P=1800
doubles in value every 7 years
so, we can find function

now, we can plug P=1800

now, we can plug t=42
