A jar contains n nickels and d dimes. There is a total of 206 coins in the jar. The value of the coins is $13.95. How many nicke
OLga [1]

Answer:

73 dimes and 133 nickels

Step-by-step explanation:

$13.95 = 1395 cents

5n + 10d = 1395     (since each nickel is 5 cents and each dime is 10 cents)

5n = 1395 - 10d      (subtract 10d from both sides to solve for n)

n = 279 - 2d

n + d = 206

279 - 2d + d = 206   (substitute n with the previous expression)

279 - d = 206         (add variable d and -2d)

-d = -73        (solve for d and divide both sides by negative 1)

d = 73          

n + 73 = 206 (solve for n and subtract both sides by 73)  

n = 133

The interest rate is 3.5%.

EXPLANATION

We substitute the given values into the formula;

A=P(1+\frac{r}{100})^t

to obtain

6427.35=6000(1+\frac{r}{100})^2

We divide through by 6000 to obtain,

\frac{6427.35}{6000}=(1+\frac{r}{100})^2

This implies that,

1.071225=(1+\frac{r}{100})^2

We take the square root of both sides,

\sqrt{1.071225}=(1+\frac{r}{100})

This gives us,

1.035=(1+\frac{r}{100})

Add -1 to both sides of the equation to obtain

0.035=\frac{r}{100}

Multiply through by 100 to obtain;

r=3.5%

Therefore the rate is 3.5%

Javier earns $7.50 per hour and works 20 hours per week. He wants to know how many weeks, w, he will need to work to save
disa [49]

Answer:

8 weeks

Step-by-step explanation:

So first you find out how much money he makes per week, by doing 7.5 x 20 you will find that. Now you need to find how many weeks it will take, find this by dividing 1200 by the amount he makes per week and you will end up with 8.
