You deposit $100 in an account earning 4% interest compounded annually. How much will you have in the account in 10 years? Round
rosijanka [135]

Answer:

$148.02

Step-by-step explanation:

In the question

Principal = $100, rate(R) = 4% compounded annually, time(T)= 10 years

we know that the formula for compound interest

A=P\times_(1+\frac{R}{100} )^{T}   where A is amount

now putting values in the above formula we get

A=100\times_(1+\frac{4}{100} )^{10}

therefore A= $148.024428

rounding off to the nearest penny we get amount as $148.02 and compound interest will be $48.02

5. which ordered pair is a solution pf the equation y = -5x + 4
Liono4ka [1.6K]

1. Replace x with the given values and see if the equation equals the Y value:

y = -5x +4  

 -5(5)+4 - -25 +4 = -21

The answer is D.


2. -4 = g+1

Subtract 1 from each side:

-5 =g

The answer is C.


3.  The 2nd chart is correct, ( the top one on the picture with 2) because when Tony is 5 the line is on Y = 0, when the line is on 6 it is on Y=1, which keeps Tony at 5 years older.

Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.
emmasim [6.3K]

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n  = 3.48

n = \frac{3.48}{0.29}

  = 12

Therefore, Kamila bought 12 pens.
