PLEASE HELP I HAVE 21 POINTS PLEASE Part A: The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. How many ergs of rad

Ahat [919]

Answer:

Step-by-step explanation:

Part A;

$\frac{3.9\times10^3^3}{1} = \frac{x}{1.44\times 10^7} \\Cross\Multiply\\x = 3.9\times 10^3^3 \times 1.44 times 10^7\\\\x = 6.045\times 10^4^0$

Part B ;

$1.435 \times 10^3 \:mm = 1.4\m\\1.435 \times 10^-^3\: mm = 0.001435\m$

The more reasonable one is 1.4m .0.001435 is too small(its not even up to 1)

Peter invests $525 at a simple interest rate of 4%. How much interest will he earn after 6 years?

Anna71 [15]

He will earn $126 in interest.
How did I solve this:
Find the decimal of 4%:
4% = 0.04
Multiply 0.04 times 525:
0.04 x 525 = 21
Multiply $21 times 6 years:
21 x 6 = 126
126 is your correct and finale answer.
Hope this helps! =)
