Answer:
n= 5.57 years
Step-by-step explanation:
Giving the following information:
your final balance on an investment of 270$ invested at 10% was $459.00
<u>To calculate the time passed between values, we need to use the following formula:</u>
n= ln(FV/PV) / ln(1+i)
FV= 459
PV= 270
i= 0.1
n= ln(459/270) / ln (1.1)
n= 5.57 years
Hello!
∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:
∠E + 119 = 180
Now subtract 119 from both sides of the equation:
∠E = 61
We have now proven that ∠E is equal to 61 degrees.
I hope this helps!
Answer:
92 92 238
Step-by-step explanation: 92 because a proton and electron have the same and first is 92 and well 238
Answer:
C. 18°
Step-by-step explanation:
The <em>order of symmetry</em> (n) is the number of times a shape fits onto itself during a complete turn through 360°.
The <em>angle of rotational symmetry</em> (θ) is the smallest angle through which the shape must be rotated to coincide with itself.
To find the angle, y<em>ou divide the number of degrees in a circle by the order of symmetry</em>.
θ = 360/n
= 360/20
= 18°
