Answer:

Step-by-step explanation:

Solving Exponential Equations with Different Bases.

Step 1: Determine if the numbers can be written using the same base. If so, stop and use Steps for

Solving an Exponential Equation with the Same Base. If not, go to Step 2.

Step 2: Take the common logarithm or natural logarithm of each side.

Step 3: Use the properties of logarithms to rewrite the problem. Specifically, use Property 5 which

says

Step 4: Divide each side by the logarithm.

Step 5: Use a calculator to find the decimal approximation of the logarithms.

Step 6: Finish solving the problem by isolating the variable.

$(2^8 \times 5^{-5} \times 19^0)^{-2} \times (\dfrac{5^{-2}}{2^3})^4 \times 2^{28} =$

$= 2^{-16} \times 5^{10} \times 1 \times \dfrac{5^{-8}}{2^{12}} \times 2^{28}$

$= 2^{-16} \times 5^{10} \times 5^{-8} \times 2^{-12} \times 2^{28}$

$= 2^{-16} \times 2^{-12} \times 2^{28} \times 5^{10} \times 5^{-8}$

$= 2^{-16-12+28} \times 5^{10-8}$

$= 2^{0} \times 5^{2}$

$= 1 \times 25$

$= 25$

You need 23 yards of fabric to make five dresses. How many yards of fabric would be needed to make 8 dresses?

olasank [31]

Answer:

36.8 or 37 yards of fabric

Step-by-step explanation:

23 yards of fabric = five dresses

23 divided by five equals four point six

four point six multiplied by eight dress equals 36.8

23 yds of fabric = 5 dresses

23÷5=4.6

If you need to know how many yards of fabric, then you'd do:

4.6×8

4.6 is the amount of each yards 5 dresses are in and so if you times that by how many dresses you need now, you'll get:

36.8 yards of fabric

To round, it'd be 37 yards of fabric
