4) Area is 48 I believe because 6x8 is 48
8) Same explanation but 4x8 making the area 32.
2) Area: 1 because 1x1 is 1
3) Area: 36 because 4.5x8 is 36
X=first train speed
y=second train speed
sum of speeds is 725.2
x+y=725.2
x is 10.8 more than y
x=10.8+y
subsitute 10.8+y for x
10.8+y+y=725.2
10.8+2y=725.2
minus 10.8 from both sides
2y=714.4
divide both sides by 2
y=357.2
x=10.8+y
x=10.8+375.2
x=386
the speed of first train is 386mph
second train is 357.2mph
Answer:
11.2 miles
Step-by-step explanation:
We can create a triangle from the information given.
<u>We can call the starting point (0,0) in the coordinate system.</u>
- <u>10 mi east</u> - 10 miles to the right. then,
- <u>5 mi north</u> - 5 miles above
<em><u>See the attached picture. The direct distance is labeled as x.</u></em>
Now we need to find x using pythagorean theorem.
Pythagorean Theorem = leg²+leg²=hypotenuse²
Solving for x:

<em>Rounding to nearest tenth, we have </em><em>11.2 miles</em>
