2.54 cm/ 1 in = 60 in/ 1. Then you would multiply 2.54 by 60 and get 152.4 cm
Here is the set using D = rt.
Jet 1:
rate = 377 mph
time = x
Distance = 9128 miles
Jet 2:
rate = 275 mph
time = x
Distance = 9128 miles
Equation:
377x + 275x = 9128
You finish.
Answer: -4/3
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Making the appropriate substitutions, we get
3/7 r + 5/8 s => 3/7 (14) + 5/8 (8).
Notice how this can reduced:
3(14) 5(8)
----------- + --------- = 6 + 5 = 11
7 8
Answer:
Step-by-step explanation:
The better buy is the one where you get more area of pizza per dollar (area/price).
Since the problem gives diameter, we assume the pizzas are circle-shaped.
Circle Area = pi x (radius)², and radius r = 1/2 of diameter d.
*************************************************************************************
Pizza 1: d = 8 and price is $10
r = 1/2 x d = 4
Area of Pizza 1 = πr² = π(4)² = 16π
*** area/price for Pizza 1 = 16π/$10 = 1.6π area per dollar
**********************************************************************************
Pizza 2: d = 14 and price is $16
r = 1/2 x d = 7
Area of Pizza 2 = πr² = π(7)² = 49π
*** area/price for Pizza 2 = 49π/16 = 3.0625π area per dollar
***********************************************************************************
Pizza 2 is the better buy, with more pizza per dollar.
