Answer:

Step-by-step explanation:

Assuming he jogs 6 miles a day (Monday to Saturday?)

6 miles * 6 days = 36 miles

Sunday = 5 miles

In one week he runs a total of 41 miles

36 + 5 = 41 miles

In 3 weeks he runs a total of 123 miles

41 * 3 = 123 miles

Can someone help me with this? :)

Answers

C is the answer
Step by step explanation:
To get the answer you must expand the brackets (multiply the number or numbers outside the brackets with the ones within to remove them)
To do this you must first in 2(8+6) multiply 2 times 8 which is 16
Then you would multiply 2 times 6 which is 12
As the operation is a + that would mean the answer is 16+12
Hope this helps!
The answer is c! 16 + 12

Find the annual simple interest rate. I=$17, P=$500, t=2 years

Answers

Answer:

The annual simple interest is 1.7%

Step-by-step explanation:

We are given I=$17, P=$500, t=2 years

Formula:

SI= PRT

where,

SI = Simple Interest (SI=$17)

P = Principle (P=$500)

R = Rate of interest  (R=?)

T = Time (T=2)

Substitute the values into formula

17 = 500 x R x 2

R = 1.7%

Hence, The annual simple interest is 1.7%
