Which expression is equivalent to (7^3)^−2?

1 answer:

8 0

Use the exponent property regarding a power to power. When you have a power to power, you multiply both powers. In this case, you will get 7^-6. That is equivalent to the first option. I hope this helped, though it is a bit late xD.

Robert slices a large loaf of bread to make 12 sandwiches. He made 3 turkey sandwiches and 5 veggie sandwiches. The rest are ham

lions [1.4K]

We already know that there are 12 sandwiches.

If there are 3 turkey and 5 veggie then there's 8 out of 12 sandwiches that aren't ham.

12 sandwiches - 8 non-ham sandwiches = 4 ham sandwiches

Now we know there are 4/12 ham sandwiches

We need to simplify this now.
4/12 can be divided by 4

4 goes into 4 1 time and 4 goes into 12 3 times making the answer 1/3

1/3 of the sandwiches are ham.

Answer:

4 cm

Step-by-step explanation:

The ratio of AD to DC is 6:12 which is equivalent to 1:2. For the ratio of WZ to ZY, we want to find half of 8 cm from ZY, for this case, it is 4 cm which makes the ratio 4:8.
