13.23 miles
Step-by-step explanation:
The vector creates an inverted right-angled triangle. The westbound car will have covered 20 miles while the southbound car will ahve covered 15 miles in 30 mins;
40 miles /hr * ½ hr = 20 miles
30 miles/ hr * ½ hr = 15 miles
To find the hypotenuse (distance between the two cars), we shall use the formulae;
a² + b² = c²
20² + 15² = c²
c² = 20² – 15²
c² = 175
c = 13.23

Answer:
(x,y)=(2,12).
Step-by-step explanation:
Let's find the answer using the given equations:
y1=5x+2
y2=-3x+18
Using the intersection method:
y1=y2 so:
5x+2=-3x+18
5x+3x=18-2
x=16/8=2
Using x=2 in the first equation we have:
y1=5*(2)+2=12
So, the answer is (x,y)=(2,12).
Let's check our answer:
y1=5x+2
12=5*(2)+2
12=12
y2=-3x+18
12=-3*(2)+18
12=12

Answer $273.90
Step-by-step explanation:
170 x 6.7 = 1139
1139 move the decimal to 113.9
113.9 + 170 = 283.90
The answer is -2.67. You move 48 to the other side of the = sign and that = -48, then you divide -48 by 18 and you get -2.67.
