72 is the length d of how deep end in feet}
Answer:
$2.85
Step-by-step explanation:
First, add the bill up ($8.70 + $10.30 = 19). So now you need to find what 15% of $19 is...To find the percentage of something you need to turn it into a decimal, 0. (whatever the percentage number is). So in this case, 19 times 0.15, which is a tip of $2.85.
Answer:
15
Step-by-step explanation:
First, find x
set your formula up as 3x+5=6x-10, since AB and DC are the same length.
This means x = 5
Now substitute 5 for x in the line DA
4x-5
4 * 5 - 5 = 15
Answer:
x= -1/2
Step-by-step explanation:
1. Create an equation
8x+4=0
2. Subtract 4 from both sides of the equal sign
8x = -4
3. Divide 8 from both sides of the equal sign to get x by itself
x= -4/8
4. Simplify
x= -1/2
Answer: <em>tan35 = appr .700207..
</em>
<em>and 12tan35 = 8.40249...</em>
Step-by-step explanation:
<em>x/12 = TAN 35
</em>
<em>x = 12 (TAN 35)
</em>
<em>x = 12 (sqrt3 / 3)
</em>
<em>x = 6.9</em>
