Pedro is building a spice rack with 4 shelves that are each 0.55 meter long. At the hardware store, Pedro finds that he can only buy the shelving in whole meter lengths. Exactly how many meters of shelving does Pedro need?

3 meters

Step-by-step explanation:

Number of shelves = 4

Length of each shelf = 0.55 meter long

Total length of 4 shelves = 4 × 0.55 meters

= 2.2 meters

Since he can only buy the shelving in whole meter lengths.

Pedro will need to buy 3 meters of shelving

He couldn't buy 2 meters because of the remaining .2 meters from 2.2 meters, therefore, the nearest whole meter length to 2 meters is 3 meters

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
