Andrew earned $125.00 last year on his investment of $10,000.00

Artemon [7]

Answer:

1,25%

Step-by-step explanation:

Aby policzyć stopę procentową należy wykorzystać podzielić otrzymany zarobek (125$) przez kwotę zainwestowaną (10.000$) a następnie pomnożyć przez 100, aby otrzymać wartość wyrażoną w procentach.

I tak mamy

$\frac{125}{10000}$ x 100 [%] = 1,25%

Tom, Sam and Matt are counting drum beats.

umka2103 [35]

Answer: $40\ beats$

Step-by-step explanation:

Knowing the information provided in the exercise, you need to find the Least Common Multiple (L.C.M) in order to solve it.

You can follow these steps:

1- You must descompose 2, 5 and 8 into their prime factors:

$2=2\\5=5\\8=2*2*2=2^3$

2- And finally, you must multiply the commons and non commons with the highest exponent:

$L.C.M=2^3*5=40$

Therefore, the answer is: $40\ beats$
