Answer:
I would try going with 12.2
Step-by-step explanation:
If I'm correct this is very simple.
x=15
So plug that into the equation and you get
11.00+0.08x15
which equals 12.2
So I recommend trying that out :)
Answer:
Your answer will be C. $5.79.
Step-by-step explanation:
To get this answer, you have to take the original price (3.99) and multiply it by the mark up (45%)
3.99x0.45=1.79
Then, you add 3.99 and 1.79 to get your final answer.
3.99 + 1.79 = 5.78
The answer is off by one penny, BUT, it's tricky to get it exact when you're working with decimals and percentages.
Answer: 8 miles.
Step-by-step explanation:
If the library is 13 miles away from the house and the park is 5 miles away from the house, 13 - 5 = 8
Answer:
A.) 2752.8 feet
B.) 5044.3 feet
C.) 6182.9 feet
Step-by-step explanation:
A.) Given that the camp to the base of the mountain is 2,000 feet. And the angle of elevation is 54 degrees
Using SohCahToa, to calculate the height
Tan 54 = height/2000
Height = 2000 tan54 = 2752.8 feet
B.) Given that the base of the mountain is 2600 feet wide.
Let use pythagorean theorem to find the slant length
Adjacent = 2600/2 = 1300 feet
Slant length = root ( 1300^2 + 2752.8^2)
Slant length = 3044.3 feet
The total distance that Jacob and his dad hiked from their campsite to the top of the mountain will be
3044.3 + 2000 = 5044.3 feet
C.) Given that the angle of depression is 24 degrees while the height is 2752.8 feet
Using pythagorean theorem again
Tan 24 = 2752.8/distance
Distance = 2752.8/tan24
Distance = 6182.9 feet
