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.
<span>The
graph of y against x in inverse proportion is a rectangular hyperbola
but I don't see at all how this knowledge/observation is any help in
solving the problem.
Inverse proportion means that as x doubles y will halve and the equation
is xy = k where k is some number. A good example of inverse proportion
is speed and time taken over some fixed distance. In this case x could
represent the speed (mph) and y the time (h) and then k is the distance
in miles.
Since we know y=3 when x=2 we have xy = 6. Now it's easy to see when x=6 y=1.</span>
Answer:
n = 5.4
Step-by-step explanation:
Equation: 4n = 21.6
To solve this equation for n, divide both sides by 4 to get n by itself.
<u />
<u>Step 1: Divide both sides by 4</u>
4 * n / 4 = 21.6 / 4
n = 5.4
Answer: n = 5.4
Answer:
0 (zero)
Step-by-step explanation:
Plug in the variable for -4 and solve
y= 2(-4)2-4(-4)
y= -8(2)-4(-4)
y=-16+16
y=0
