goldfiish [28.3K]

Answer:

a) He needs to consume 600 kcal from protein.

b) 22 kcal come from fat.

Step-by-step explanation:

a) Lee needs to consume 2400 kcal each day and 25% of this income should come from protein.

We are going to use percentages to solve this problem, to find out how many kcal from protein he should consume we need to multiply 2400 by .25.

2400 (.25) = 600

Lee needs to consume 600 kcal from protein.

b)  A cup of chili contains 220 kcal If 15% of kcal come from fat how many kcal come from fat?

We are going to solve this in a similar way.

We should multiply the total amount of kcal by .15 which is the amount of fat calories.

220 (.15) = 33

33 kcal come from fat.

Cupro-nickel coins are minted by mixing copper and nichel in the ratio 4:1
Softa [21]
Copper:   Nickel =  4:1

a) How much copper needed for 20 kg nickel
                 C:N = 4: 1 
                 C:20 = 4:1

C/20 = 4/1       Cross Multiply
C*1 = 4*20
C = 80     

80kg Copper would be needed.

b) How much Nickel would be needed for 20 kg of Copper
                 C:N = 4: 1 
                 20:N = 4:1

20/N = 4/1       Cross Multiply
4*N = 1*20
4N = 20   Divide both sides by N.  

N = 20/4 = 5

5kg Nickel would be needed.
