Answer:
22
Step-by-step explanation:
We know that 1 miles = 5280 ft and 1 hour = 3600 seconds
15 miles 5280 ft 1 hour
--------------- * ------------- * -------------- =
1 hour 1 mile 3600 second
The units cancel leaving us ft/s
22 ft/s
This is a question of randomness so there really is no answer. I would guess 7 since that is the center page and you're more likely to open it up in or near the middle
Let's find the total cost before the tax and tip.
14+16+2*1.25+2*4.25 = $41
The tip is added before the tax so let's calculate it first.
1.15 * 41 = $47.15
Now add the 7% tax.
1.07 * 47.15 = $50.45
Answer:
Step 1: 4, 1.5
Step 2: 120, 45
Step-by-step explanation:
Step 1:
4, 1.5
Step 2:
30*4 = 120
30*1.5 = 45
1. 12a²b² + -7a²b² + 9a²b²
= 14a²b² (the terms a²b² are like terms so don't look at them, just add 12 + (-7) + 9.
= 14 (ab)² (you can write like this too because both a & b are squared).
2. y² - (-5y²)
= 6y² (subtract -5 from 1, y² is the like term).
