Answer:
$20.06
Step-by-step explanation:
17 x 0.18 = 3.06 Multiply the cost by the tip percent
17 + 3.06 = $20.06 Add the tip amount to the original cost
Answer:
B. 2
Step-by-step explanation:
1) all the perpendicular lines are: y=x+C, where C - number;
2) in order to calculate C: to substitute (2;4) into the equation y=x+C:
4=2+C; ⇒ C=2;
3) finally, the required equation is: y=x+2.
The answer is B. 2.
Paul's age = 6 years + Corinne's age
<span>(Paul's age - 10 years) = 3 times (Corinne's age - 10 years) </span>
<span>Let's rewrite it so it's cleaner: </span>
<span>P = 6 + C </span>
<span>P - 10 = 3(C - 10) </span>
<span>Question is P = ? years. </span>
<span>P = ? = 6 + C </span>
<span>We need to know what C is... the second equation can tell us: </span>
<span>P - 10 = 3C - 30 </span>
<span>P + 20 = 3C </span>
<span>P/3 + 20/3 = C </span>
<span>So now we know what C is... we can replace it into the first equation: </span>
<span>P = 6 + [P/3 + 20/3] </span>
<span>we just need to simplify now... it's easiest to get rid of the fractions first: </span>
<span>3P = 18 + P + 20 </span>
<span>2P = 38 </span>
<span>P = 19 </span>
<span>Answer is Paul's age is now 19 years.</span>
Answer:
c=10 units
Step-by-step explanation:
The Pythagorean Theorem states that a^2+b^2=c^2.
This means that the sides are represented by a^2+b^2. In order to find the hypotenuse in this problem, we substitute a and b for 6 and 8.
6^2+8^2=c^2
we do what it shows us and get:
36+64=c^2
from there, we add the left side altogether then square each side to get rid of the root.
100=c^2
√100=√c^2
and we get c =<em> 10 units.</em>
