Answer:

  1/8, 3/8

Step-by-step explanation:

Let x and y represent the two fractions. Then we are given ...

  x + y = 1/2

  x + 5y = 2

Subtracting the first equation from the second, we get ...

  (x +5y) -(x +y) = (2) -(1/2)

  4y = 3/2 . . . . . simplify

  y = 3/8 . . . . . . divide by 4

  x = 1/2 -3/8 = 1/8

The two numbers are 1/8 and 3/8.

What is the total cost of a sweatshirt if the regular price is $42 and the sales tax is 5 1/2
leonid [27]

Answer:

$44.31

Step-by-step explanation:

Regular Price = $42

Sales Tax Rate = 5  1/2% or 5.5%

The total cost would be the regular price PLUS the sales tax. We find the sales tax by finding 42's 5.5%.

First, converting percentage to decimal (dividing by 100):

5.5% = 5.5/100 = 0.055

Now finding 5.5% of $42:

42 * 0.055 = $2.31

Now, the total price is the SUM of regular and this sales tax:

Total Price = 42 + 2.31 = $44.31

Anthony has $3750 that he wants to invest. He plans to leave the money there for 9 years. If his investment gets 6.35% interest
xenn [34]

Answer:

A= P(1+\frac{r}{n})^{nt}

P = 3750

r = 6.35% = 0.0635

n = 365

t = 9

A= 3750(1+\frac{0.0635}{365} )^{365*9}\\\\

    = 3750(1+\frac{0.0635}{365})^{3285} = 6640.63

Answer  = $6641
