The amount of mass after 5 minutes is 75.74 grams.
It is given that
The amount initially = 330grams
After every minute mass decays by 25.5%
<h3>What is the percentage?</h3>
The percentage is the value per hundred.
Amount after 1 min = 330-330*25.5/100 = 245.85grams
Amount after 2 min = 245.85-245.85*25.5/100 = 183.16grams
Amount after 3min = 183.16-183.16*25.5/100 = 136.45grams
Amount after 4 min = 136.45-136.45*25.5/100= 101.66grams
Amount after 5 min =101.66-101.66*25.5/100 = 75.74grams
Therefore, the amount of mass after 5 minutes is 75.74 grams.

Answer:
Basically you plug the numbers in. x=-2, so it would be 3(-4+1)^3. That can be simplified to -81, e. Please give Brainliesttt!!!!
Step-by-step explanation:
Answer:
146°; 34°
Step-by-step explanation:
Supplementary angles are two angles whose measures sum up to equal 180°. The supplement of one angle = 180° - its measure.
Given that an angle measures 112° more than its supplementary angle,
let x = the angle (larger angle)
Supplement of x = (180 - x) (smaller angle)
x = (180 - x) + 112
Solve for x
x = 180 - x + 112
x + x = 180 - x + 112 + x
2x = 180 + 112
2x = 292
2x/2 = 292/2
x = 146
The angle is 146°
Its supplement is 180 - 146 = 34°
