Hey there!

To start, this is a compound interest problem, meaning you will have to use this formula:
A=P(1+\frac{r}{n})^nt

P represents the principal amount, r represents the rate as a decimal, n represents the amount of times compounded, and t represents the number of years compounded.

Now, plug in your known values:
P=300 (your initial amount)
r=0.02 (your rate of 2%)
n=1 (compounded annually, meaning once every year)
t=4 (the number of years you need to find)

A=300(1+0.02/1)^(1*4)

Now, simplify:
A=300(1+0.02)^4
=300(1.02)^4
=300(1.08243216)
=324.729648

Finally, round to the nearest cent and you get $324.73 as your final answer.

Jack has twice as many dimes as quarters. If the total value of the coins is $6.30, how many dimes does he have?
ycow [4]

Answer:

Number of dimes = 28

Step-by-step explanation:

Given that:

Worth of coins = $6.30 = 6.30 * 100 = 630 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement;

x = 2y    Eqn 1

10x+25y = 630    Eqn 2

Putting x = 2y in Eqn 2

10(2y) + 25y = 630

20y + 25y = 630

45y = 630

Dividing both sides by 45

\frac{45y}{45}=\frac{630}{45}\\y=14

Putting y=14 in Eqn 1

x = 2(14)

x = 28

Hence,

Number of dimes = 28

Perimeter of a triangle is 27cm,if two sides measure 9cm and 7.8cm,find the measure of third side?
fredd [130]

Answer:

10.2cm

Step-by-step explanation:

Perimeter is the sum of the lengths of all sides.

1st side: 9cm

2nd side: 7.8cm

Perimeter: 27cm

Perimeter = 1st + 2nd +3rd side of a triangle

27cm = 9cm +7.8cm + 3rd side

3rd side = 27cm - 9cm -7.8cm

              = 10.2cm
