Answer:
2 bags of stone
Step-by-step explanation:
Lets do one at a time. Cement first.
he needs 180 kg of cement.
1 bag is 25 kg, so in total he needs 8 because 7 would get him 175, so he would need just a little bit more. And I assume you can't but part of a bag he needs to but one full more bag. If he already has 8 then he doesn't need any more.
Needs 375 kg of sand
Each bag has 22.5 kg inside
he needs 17 bags total of sand because 16 would only give 360
Since he already has 19 bags he has 427.5 kg of sand so he doesn't need any more.
Needs 1090 kg of stone
Each bag has 50 kg of stone
He needs 22 bags since 21 would just give him 1050 kg
He has 20 so he needs two more bags
So in total he needs two bags of stone. Let me know if there was anything you didn't understand.
<u>Answer:</u>
$3.80
<u>Step-by-step explanation:</u>
We are given a graph showing the location of 3 houses where you had to do lawn work today, with the distances from your house.
Given that one truck gets 8 miles per gallon of gasoline and gas costs $1.52 per gallon, we are to find the total cost of the gas used.
Total distance = 7 + 3 + 4 + 6 = 20 miles
Gallons of gas used = 20 / 8 = 2.5
Total cost of gas used = 2.5 * 1.52 = $3.80
