We know that

• The new charge was $0.50 to mail a letter weighing up to 1 ounce, and $0.21 for each additional ounce.

Based on the given information, the expression is

y=0.50+0.21x

Where <em>x</em> represents additional ounces, and <em>y</em> represents a cost.

<h2>Hence, the function is</h2>f(x)=0.21x+0.50

Can you please help me out?
larisa86 [58]

Answer:

- 3.5229

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

log_{10} 10^{n} = n

Given

log_{10} 3 ≈ 0.4771, then

log_{10} 0.0003

= log_{10} (3 × 10^{-4} )

= log_{10} 3 + log_{10} 10^{-4}

≈ 0.4771 - 4

≈ - 3.5229 ( to 4 dec. places )

What is the dollar value of 7 nickels and 8 quarters
victus00 [196]

Answer:

$2.35

Step-by-step explanation:

Nickels are worth 5 cents each and quarters are worth 25 cents.

7 nickels = 7 * 5 cents = 35 cents

8 quarters = 8 * 25 cents = 200 cents

Total = 200 + 35 = 235 cents

There are 100 cents per dollar, so we can find the dollar value by:

235/100 = $2.35
