The Reyes want grilled chicken and tilapia for dinner. Mrs.

seropon [69]

Answer:

Kilogram of chicken = 1

Kilogram of tilapia = 3

Step-by-step explanation:

Cost of chicken = 150 per kilo

Cost of tilapia = 100 per kilo

Number of kilos of each if total cost should not exceed 450

Let :

Number of kilo of chicken = x

Number of tilapia kilo = y

The constraint :

150x + 100y ≤ 450

We could choose some reasonable values of x and y then, test the constraint ;

If x = 1 and y = 3

150(1) + 100(3) = 450

Hence,

1 kilo of chicken with 3 kilos of tilapia offers the greatest combination of Number of kilograms of tilapia and chicken that could be purchased and still satisfy the maximum cost constraint.

What is the value of the expression 6 and 3 over four multiplied by negative 11. 5?.

Margarita [4]

The value of the expression (6¾) × -11.5 is; -77⅝

We want to find the value of;

(6¾) × -11.5

Let us change 6¾ to improper fraction to get;

27/4

Also,let's change -11.5 to an improper fraction to get; -115/10

Thus;

(6¾) × -11.5 = 27/4 × -115/10

>> (-115 × 27)/(40)

>> 3105/40

>> -77⅝

On his death, a wealthy businessman left R132 000 to charity. He declared that the money should be given to the following charit

Nutka1998 [239]

Answer:

The Reach for a Dream Foundation received R33000, NSPCA received R44000, and Smile received R55000.

Step-by-step explanation:

Total money for charity = R132,000

Ratio:

3 : 4 : 5

Charities:

The Reach for a Dream Foundation : NSPCA : Smile

x : y : z

3x + 4y + 5z = R132000

Charity 1 = Charity 2 = Charity 3

x = y = z

3x + 4x + 5x = R132000

x = 11000

The Reach for a Dream Foundation:

3(11000) = R33000

NSPCA:

4(11000) = R44000

Smile:

5(11000) = R55000

Double Check:

R33000 + R44000 + R55000 = R132000
