The revised Daily Value for calcium is 1,300 mg per day. How many servings of this food would you have to eat to get 100% DV for
Ne4ueva [31]

Answer:

Taking into account the values showed for this food (image attached). It is required

5  

Servings.  

Step-by-step explanation:

The total calcium (Cat) required is 1300 mg/day.  

One serving of this food can have 260 mg.  

First step is to suppose one day of calculation. t = 1 day.

Cat = (1300 mg/day)(1 day) = 1300 mg Calcium.

One single serving can have 260 mg Calcium (Cas). So, we need to calculate the amount of servings (N) required to complete 1300 mg.

Cat = Cas*N

N = Cat/Cas = 1300 mg/260mg

N = 5.

Finally amount of servings is five N = 5.

cupoosta [38]
Number of sides= 10
Side length= 4.6 ( or in this case base)

161 sq inches / 10 = 16.1 area of triangle.

Area of triangle =(b<span>ase * </span>height)/2 

16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)

32.2=4.6*h
divid 32.2 by 4.6

<span>7 is the height of the triangle</span>
