10:57 AM , if you subtract each amount from 2:40 PM, you should get 10:57 AM.
The measure of angle 1 is 75 degrees because it is a corresponding angle with the one given of 75 degrees
the measure of angle 2 is 105 degrees because it forms a supplementary angle with the one next to it that is 75 degrees. (this means they add up to 180 degrees.
Sheldon would have $21,386, while Howard would have $20,073.
The equation for each of these will be in the form
,
where A is the total amount in the account, p is the principal invested, r is the interest rate expressed as a decimal number, and t is the amount of time.
For Sheldon:
A=15000(1+0.03)¹²=15000(1.03)¹²=21386.41≈21386
For Howard:
A=15000(1+0.06)⁵=15000(1.06)⁵=20073.38≈20073
63.3% decrease
49 - 18 = 31
31/49 = 0.63265 x 100
= 63.3 rounded to the nearest tenth of a percent
