Ierofanga [76]

Answer:

To obtain equivalent amount from both foods we can eat 10 ounces of Food I and 5 Ounces of food II

To obtain minimum cholesterol, the individual should eat only 21 ounces of food II and zero ounce of food for the daily supplement of the individual

Step-by-step explanation:

Food I contains 32×C + 10×E per ounce

Food II contains 20×C + 14×E  

Here we have X × (Food I) + Y × (Food II) = 420 C + 170 E

32·X + 20·Y = 420 C

10·X + 14·Y = 170 E

Therefore

X = 10 and Y = 5

To minimize the cholesterol, we can increase amount of Food II to get

21 ounces of food II gives

420 units of vitamin E and 294 units of vitamin E with 273 units of cholesterol.

Annually The amount after 10 years = $ 7247.295

quarterly compound after 10 years = $7393.5

Continuously interest =$7,419

Given:

P = the principal amount

r = rate of interest

t = time in years

n = number of times the amount is compounding.

Principal =  $4500

time= 10 year

Rate = 5%

To find: The amount after 10 years.

The principal amount is, P = $4500

The rate of interest is, r = 5% =5/100 = 0.05.

The time in years is, t = 10.

Using the quarterly compound interest formula:

A = P (1 + r / 4)4 t

A= 4500(1+.05/4)40

A= 4500(4.05/4)40

A= 4500(1.643)

Answer: The amount after 10 years = $7393.5

Using the Annually  compound interest formula:

A = P (1 + r / 100) t

A= 4500(1+5/100)10

A= 4500(105/100)10

Answer: The amount after 10 years = $ 7247.295

Using the Continuously  compound interest formula:

e stands for Napier’s number, which is approximately 2.7183

A=Pex^{rt} \\A=4500(e)^{.5} \\A= 4500(2.71)^{.5}

A= $2,919

Answer: The amount after 10 years = $4500+$2,919=$7,419

Rewrite the equation below so that it does not have fractions.
Leviafan [203]

9514 1404 393

Answer:

  8x -24 = 9y

Step-by-step explanation:

We assume your equation is ...

  2/3x -2 = 3/4y

__

Fractions can be eliminated by multiplying the equation by the least common denominator of the fractions.

  LCM(3, 4) = 12

Multiplying the equation by 12 gives you ...

  12(2/3x -2) = 12(3/4y)

  8x -24 = 9y

2. The area of a square is 72 sq in. What is its side length?
defon

Answer:

6 \sqrt{2}

if you don't have to simplify it, it is

\sqrt{72}

Step-by-step explanation:

the equation for the area of a square is

a =  {s}^{2}

substitute 72 for a

72 =  {s}^{2}

take the square root of both sides to cancel out the square on the s

\sqrt{72}  =  \sqrt{ {s}^{2} }

\sqrt{72}  = s

if you need it simplified, find the perfect square that makes up 72. It is 36.

\sqrt{36 \times 2}  = s

take the square root of 36

6 \sqrt{2}  = s
