Answer:
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Step-by-step explanation:
Let r be a ratio useful in determining how much of each ingredient Henry needs:
4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.
4/8 of the total 120 kg must then be 60 kg made up of cement;
3/8 must then be 45 kg made up of sand; and
1/8 must then be 15 kg made up of gravel
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Isn’t it the theoretical probability?
Answer:
I think it would be (1,-2)
Step-by-step explanation:
I can verify that it is a solution because y=1-3 is the same solution as y=-3+1
The results would be x=-2 for both
Answer:Roast beef- 32 turkey-80 Vegetarian-48
Step-by-step explanation:
This is the answer because if you divide 160 divide by 5 that gives you 32 for the roast beef. For the turkey you divide 160 and 3 that gives you 80. For the vegetarian you have to add 32 and 80 that gives you 112. Then, you subtract 160 and 112 that gives you 48. To check your answer you add 32, 80, and 48 that gives you 160.
I know the answer but let me just make sure that it is correct
