Using a system of equations, the amounts in grams of each mix that should be used are given as follows:

  • A: 60 grams.
  • B: 50 grams.
  • C: 40 grams.

<h3>What is a system of equations?</h3>

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.

For this problem, the variables are given as follows:

  • Variable a: number of grams of substance A.
  • Variable b: number of grams of substance B.
  • Variable c: number of grams of substance C.

The mix has 23g of protein, hence, from the table:

0.2a + 0.1b + 0.15c = 23.

The mix has 6.2g of fat, hence:

0.02a + 0.06b + 0.05c = 6.2.

The mix has 16g of moisture, hence:

0.15a + 0.1b + 0.05c = 16.

Hence the system is given by:

  • 0.2a + 0.1b + 0.15c = 23.
  • 0.02a + 0.06b + 0.05c = 6.2.
  • 0.15a + 0.1b + 0.05c = 16.

Using a calculator, the solution for the system is given as follows:

a = 60, b = 50, c = 40.

Which are the amounts in grams of each substance.

<h3>What is the missing information?</h3>

The table containing the compositions of the mix is missing, and is given at the end of the answer.

14 and 11/12 + 3 and 1/6
Stells [14]

let's firstly convert the mixed fractions to improper fractions and then add them up, bearing in mind that the LCD from 12 and 6 will just be 12.

\bf \stackrel{mixed}{14\frac{11}{12}}\implies \cfrac{14\cdot 12+11}{12}\implies \stackrel{improper}{\cfrac{179}{12}}~\hfill \stackrel{mixed}{3\frac{1}{6}}\implies \cfrac{3\cdot 6+1}{6}\stackrel{improper}{\cfrac{19}{6}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{179}{12}+\cfrac{19}{6}\implies \stackrel{\textit{using the LCD of 12}}{\cfrac{(1)179~~+~~(2)19}{12}}\implies \cfrac{179+38}{12}\implies \cfrac{217}{12}\implies 18\frac{1}{12}

A hot air balloon descends 15 feet each minute after having reached an altitude of 362 feet above the ground. What is the altitu
salantis [7]

Answer:

182 feet

Step-by-step explanation:

The equation that describes the motion of the hot air ballon is:

h(t) = h_0 - vt

where:

h_0 is the initial altitude

v is the rate of descend of the balloon

t is the time

The balloon starts from a height of

h_0 = 362 ft

and has a rate of descend of

v=15 ft/min

Therefore, after time

t = 12 min

Its altitude will be

h(12)=362 - (15)(12)=182 ft
