Step-by-step explanation:
Answer:
Step-by-step explanation:
-2/7x -5 =13
-2/7x = 13 + 5 = 18
x = 18 (-2/7)
x = -5.14
To work out the area of a semicircle<span> you can use the formula A = (Pi*r^2)/2. This is because the </span>area<span> of a full</span>circle<span> is A = Pi*r^2 and a </span>semicircle<span> is </span>half<span> the </span>area<span> of a full</span>circle<span> so you divide this by 2. Just be careful to substitute the radius into the formula and not the diameter!

Let the relative speed will be given by:
38/4=9.5 km/h
Let the speed of the first tourist be x km/h
the speed of the second one is (9.5-x) km/h
distance covered by the first one is:
4*x+2=4x+2 km
distance covered by the second one is:
(9.5-x)4 km
=(38+4x) km
total distance will be given by:
(38+4x)+(4x+2)=38
40+8x=38
8x=-2
x=-1/4 km/h
this mean that he was traveling in the opposite direct thus the speed was 1/4 km/k
The speed of the second one will be:
9.5-1/4=9.25 km/h
Answer:
Tip given to the server be $6.44 .
Step-by-step explanation:
As given
The Edwards family's bill for dinner is $42.95.
The normal tip is 15%.
15% is written in the decimal form .
= 0.15
Tip given to the server = 0.15 × Cost of the dinner
Putting all the values in the above
= 0.15 × 42.95
= $6.44 (Approx)
Therefore the tip given to the server be $6.44 .
