Answer:

The total weight would be 5 lbs 12 oz.

Step-by-step explanation:

First, combine the ounces:

13 + 15 = 28 ounces

Next, convert that into pounds and ounces.

28 oz = 1 lb + 12 oz

Finally, add the weight back to the 4 lb.

1 lb + 4 lb + 12 oz = 5 lb + 12 oz

Find the size of angle XZY<br> Give your answer to 1 decimal place<br> 15cm<br> 6cm
Natali [406]

Answer:

The equation would be 6^ + b^ = 15^

First we bring each number to the power of two, 6^ = 36, and 15^ = 225

Then we subtract 36 from 225 and we get 189.

Then we "Square root" 189 because of the 2nd power on top of B

The correct answer is 13.8

I hope this helps :)

STAY SAFE!! :D
