Answer:
Step-by-step explanation:
m is number of miles
A: 45+0.21m (45 is the initial cost)
B: 28+0.38m (28 is the initial cost)
To know how in many miles the cost will be equal,
45+0.21m=28+0.38m
0.38m-0.21m=45-28
0.17m=17
m=17/0.17 = 100
So, at 100 miles the cost will be same for company A and B.
Answer:
3. 15 Cubes
4. 60 ft per sec , 180 ft
5. 58 yards per min
6. $7.50, $18.00
Step-by-step explanation:
3. Number of Cubes in 7 bowls = 35
Number of Cubes in 1 bowls = 
Number of Cubes in 3 bowls =
4. Distance ran by Zebra = 420 ft
Time taken = 7 seconds
Speed =
=60 ft per sec
Hence
Distance = speed x time
Distance covered in 30 seconds = 60 x 30 = 180 Ft
5. Distance travelled = 870 yards
Time taken = 15 mins
Speed =
yards per min
6. Cost of 3 pounds of apple = $4.50
Cost of 1 pounds of apple =
=$1.50
Cost of 5 pounds of apple = 5 x $1.50 =$7.50
Cost of 12 pounds of apple = 12 x $1.50 =$18.00
