Answer:
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
Considering the first account,
T = 1 year
P = $10000
R = 5%
I = (10000 × 5 × 1)/100 = $500
The total amount = 10000 + 500 = $10500
he moved the total amount to a new account earning 6% interest. Therefore,
P = 10500
R = 6%
T = 1
I = (10500 × 6 × 1)/100 = $630
The amount of money that Marty would have at the end of the second year is
630 + 10500 = $11130
Answer: 12.6 miles
Step-by-step explanation:
Here the ship is doing a circular path.
We know that the ship is 120° from the north, and we want to find the distance that the ship has traveled so far from the most northern tip of the island.
This distance will be equal to the length of the arc of 120°
You can find this as:
Arc = (angle*3.14/180)*radius
arc = (120*3.14/180)*6 miles = 12.56 miles
Now we need to round it to the nearest tenth, so we need to round it up, and we get 12.6 miles
Answer:
170
Step-by-step explanation:
10 x 15 = 150
2.5 x 4 = 10
10 x 2 = 20
150 + 20 = 170
