Answer:
19.4 =u
Step-by-step explanation:
17/7 = u/8
We can use cross products to solve
17*8 = 7u
Divide each side by 7
17*8/7 = 7u/7
19.42857143 = u
To the nearest tenth
19.4 =u
Answer:
2850
Step-by-step explanation:
You pay 3% on the first 10,000, 5% on the next 40,000, and 5.5% on the last 10,000.
10,000x.03=300
40,000x0.05=2000
10,000x.055=550
2000+550+300=2,850
Use the Pythagorean theorem
a^2 + b^2 = c^2
a^2 + 15^2 = 25^2
a^2 + 225 = 625
a^2 = 400
a = 20
