Manny has $650 in his savings
Bumek [7]

Answer:

Interest Manny earns after 2 years is  $52

Step-by-step explanation:

Amount deposited = $650

Simple annual interest rate = 4%

To find: Interest after 2 years

We know that the formula to calculate the interest amount is

Simple interest (S.I.) =  \frac{Prt}{100}

where,

P is the initial amount deposited

r is the rate of simple interest in percentage

t is the time in years for which interest is to be calculated

Substituting the known values in the formula, we get

S.I =  \frac{650 x 4 x 2}{100}

   = 52

Hence the interest Manny earns after 2 years is  $52

Find the distance between each pair of points <br>L(-7,0) ,Y(5,9)​
Sedbober [7]

Answer:  The distance is 15

Step-by-step explanation:

To find the distance between L and Y find the difference in the x and y coordinates then square them and add them to find their square root.

-7-5= -12

0-9 = -9

12^2 + 9^2 = d^2   where d is the distance

144 + 81 = d^2

225 = d^2

d= \sqrt{225}  

d= 15
