Hey!!
Here is the answer to your question
1- B
2-A
Answer:
$11.20 per hat.
and $5.60 per bag
Keisha has $13.20 left over
Step-by-step explanation:
First, I multiplied .70 by 16 and got 11.20 per hat
Then, I multiplied .35 by 16 and got 5.60 per bag
Lastly, I added 11.20 to 5.60 and got 16.80, and subtracted 16.80 from 30 and got 13.20.....

Answer:
-101 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relevant relation is ...
Tan = Opposite/Adjacent
Opposite = Adjacent × Tan
height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft
__
The usual relation between estimates and errors is ...
error = estimate - actual
Then ...
actual = estimate - error
For the given angle and error, the actual angle is ...
actual angle = 47° -(-1°) = 48°
actual height = (2640 ft)·tan(48°) ≈ 2932 ft
Then the change in the height of the mountain due to the error is ...
2831 ft -2932 ft = -101 ft
The error of -1° in angle estimate creates an error of -101 ft in the height estimate.
