Answer:
12 and 5 inches since squaring them would equal 144+25, which is 169, and ✓169=13. the two legs have to equal the hypotenuse when combined to be a right triangle.
Use Systems of Equations:
x+y=160 ----> 1400x+1400y=224,000
1400x+1000y=182,800 ----> 1400x+1000y=182,800
Subtract the two-----> 400y=41200
Solve for y-----> 400y/400=41200/400---------> y=103
Plug in Y to the first equation then solve for X-----> x+103=160----> x=57
So the answer is 57 trucks and 103 cars
Answer:
quadratic
Step-by-step explanation:
25 x^2 +3x-2=0
The highest power of x is x^2 which makes the function quadratic
Answer:
r ≥ -1/3
Step-by-step explanation:
Answer:
e/4 = 2.5
e/ 4 × 4 = 2.5 × 4
e = 10
His mistake was in step 2 since
2.5 × 4 = 10
Hope this helps
