Answer:

<em>You would need 5,555,556 hours to count 1 billion.</em>

Step-by-step explanation:

<u>Proportions</u>

If you count one number every 20 seconds, then you can count 3 numbers in a minute.

Counting 3 numbers in a minute will allow counting 3*60 = 180 numbers in an hour.

At the same counting rate, if you wanted to count 1 billion numbers, we can calculate the hours needed by dividing:

1,000,000,000 / 180 = 5,555,555.55

Rounding to the nearest hour, you would need 5,555,556 hours to count 1 billion.

Q= 4(a+b) solve for d

alukav5142 [94]

Answer:

$b= \frac{q - 4a}{4}$

Step-by-step explanation:

ill suppose that you mean : "solve for b" not for d, since there is no d term in the formula given. So:

$q = 4(a + b) \\ q = 4a + 4b \\ 4a + 4b = q \\ 4a + 4b - 4a = q - 4a \\ 4b = q - 4a \\ b = \frac{q - 4a}{4}$

A 100 gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. the function f(

Alexxx [7]

Answer:

Shifted 5 unit right side then stretched vertically by the factor 100

Step-by-step explanation:

Here, parent function,

$f(x)=\frac{1}{x}$

Transformed function,

$f(x) = \frac{100}{x-5}$

Since, if a function f(x) gives cf(x), where c is any number,

Then the function was vertically stretched by factor c,

While, the function gives f(x-c),

Then the function was shifted c unit right.

Hence, the graph of $f(x)=\frac{1}{x}$ was shifted 5 unit right side then stretched vertically by the factor 100 to create the graph of $f(x)=\frac{100}{x-5}$

Samuel bought 32 and 1/2 ft of window trim at a hardware store the trim cost $1.75 per foot including sales tax if Samuel paid w

Sergio [31]

Answer:

The amount of change he should received is

$100 - $56.875

= $43.125

= $43.13

Step-by-step explanation:

Length of window trim = 32 and 1/2 ft

Cost per foot = $1.75

Amount paid = $100

Total cost of window trim = 32.5×1.75 = $56.875

The amount of change he should received is

$100 - $56.875

= $43.125

= $43.13
