The ratio of the amount of vitamin A in cow milk to the amount of vitamin A in goat milk is
miv72 [106K]

Answer:

2080 IU

Explanation:

Given

Ratio of vitamin A in cow milk to goat milk = 3 : 4

Required

Determine the content of vitamin A in goat milk if cow milk has 1560 IU

The given parameters shows a direct proportion.

Let G represents Goat and C represent Cow

Given that there exists a direct proportion;

C = K * G where K represents the constant of proportionality.

Solving for K when C = 3 and G = 4

C = K * G becomes

3 = K * 4

3 = 4K

Divide through by 4

¾ = K

K = ¾

Now, solving for G given that C = 1560IU;

We'll make use of the same formula as above

C = K * G

Substitute 1560 for C and ¾ for K; the expression becomes

1560 = ¾ * G

Multiply both sides by 4

4 * 1560 = 4 * ¾ * G

6240 = 3 * G

Multiply both sides by ⅓

⅓ * 6240 = ⅓ * 3 * G

2080 = G

G = 2080

Hence, the vitamin A in the goat milk is 2080IU

alina1380 [7]

Answer:

The shipping weight of one dining chair without the cushion is 10.8 lbs

Explanation:

First find the total weight of the cushions by multiplying the weight of the cushions by the amount of cushions:

2.4x8=19.2

Then, find the weight of chairs without cushions by subtracting the weight of the cushions from the total weight of the chairs with the cushions on it:

105.6-19.2=86.4

Finally, find how much one chair without a cushion weighs by dividing the total weight of the chairs without cushion by the amount of chairs:

86.4÷8=10.8

A person buying a personal computer system is offered a choice of three models of the basic unit, two models of keyboard, and tw
Anit [1.1K]

The number of distinct computer systems that this person can purchase is equal to twelve (12).

<u>Given the following data:</u>

  • Number of basic units = 3 models.
  • Number of keyboard = 2 models.
  • Number of printers = 2 models.

<h3>How to calculate the number of distinct systems.</h3>

In order to determine the number of distinct computer systems that this person can purchase, we would use a mathematical model referred to as combination.

Mathematically, combination is given by this mathematical equation:

_nC_r = \frac{n!}{r!(n-r)!}

<u>Where:</u>

  • n is the number of items.
  • r is the number of times of choosing items.

Substituting the given parameters into the formula, we have;

³C₁ × ²C₁ × ²C₁ = 3 × 2 × 2

Distinct systems = 12.
