2/3 is 2 × 1/3.
We can separate the exponent into 1/3 power raised to the 2nd power. 1/3 power is the same as cube root.
27 and 8 are both perfect cubes. 3^3 and 2^3.
Thats how you go from 27/8 to 3/2.
Then square it.

Answer:
B
Step-by-step explanation:
- First find the perdendicular slope (flip and change sign) : m= -
- Then set up your equation using the given ordered paired to find your y-intersept: -1 = -
(5) + b
- Caluclate the product: -1 = -
+ b
- Move the variable to the left-hand side and change its sign : -b - 1 = -
- Calculate the sum: -b = -
- Change the sign : b=
- Use the slope and y-intersept to creat the equation: y = -
Answer:
$4.41
Step-by-step explanation:
We have been given that Otis bought a flashlight for $8 and a sleeping bag for $55 he sales tax was 7% which means 0.07 times the price.
To find the amount of sales tax, we will add cost of sleeping bag and flashlight and multiply the sum by 0.07.
Therefore, Otis paid an amount of $4.41 in sales tax.
The 2nd way is that we can find sales tax of each product separately and then add the amount of sales of two items as:
Therefore, Otis paid an amount of $4.41 in sales tax.
