Answer:
161.63 tons
Step-by-step explanation:
Cement used per mile = total cement used / total miles
646.5 tons / 4 = 161.625 tons
161.63 tons to the nearest hundredth
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
the thousandth term is 5, so 1 would be added to 2
Answer:
c- 75
p- 25
Step-by-step explanation:
so haley has 2450 in total and the pig cost 25 so if the cows are 3 times more than the pigs . so the cows stuff cost 75 each so now multiply 75 x 30 = 2250 and the pigs cost 25 each multiply 25 x 8 = 200 then add 2250 + 200 = 2450 which means haley has the exact money to pay the stuff. haley spends 75 on each cow.
Perimeter is the sum of all 4 walls.
Divide the perimeter in half for the total of the width + the length:
26/2 = 13 meters
Subtract the difference in length:
13 - 3 = 10
Divide by 2 walls:
10/2 = 5
The width is 5 metes.
The length is the 5 metes + the 3 meter difference = 5 +3 = 8 meters.
The length is 8 meters and the width is 5 meters.
