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.

Small Town USA has a population of 4•10 to the power of 4. Big town has a population of 2•10 to the power of 5. How many times l

Kryger [21]

Big town is 5.121 times larger than Small town.

Step-by-step explanation:

Step 1:

In order to determine how much larger Big town's population is to Small town's population is, we need to convert the exponentials into actual numbers.

Small town's population $= 4.10\times 10^{4} = 41,000.$

Big town's population $= 2.10\times 10^{5} = 210,000.$

Step 2:

In order to determine how much larger Big town's population is to Small town's population is, we divide Big town's population by Small town's population.

$\frac{210,000}{41,000} = 5.121.$

So Big town is 5.121 times larger than Small town.

aleksandrvk [35]

Answer:

1022.25 square feet

Step-by-step explanation:

The length and width sum to half the perimeter, so the length is ...

P/2 -W = length = 134/2 -23.5 = 43.5 . . . . feet

The area is the product of length and width, so is ...

A = LW = (43.5 ft)(23.5 ft) = 1022.25 ft^2

The area of the garden is 1022.25 ft^2.

Multiply (2.5x10^-10) (7x10^-6)

serious [3.7K]

We want to multiply $2.5\cdot10^{-10}$ by $7\cdot10^{-6}$ .

The numbers are written in scientific notation. So we expect the answer also to be in scientific notation.

the multiplication of the 10's, using the exponents rule is :

$10^{-10}\cdot 10^{-6}=10^{-10+(-6)}=10^{-10-6}=10^{-16}$

the multiplication of the other 2 numbers is:

$2.5\cdot7=17.5=1.75\cdot10$

(we write the number so that it has only one digit to the left of the decimal point).

Thus,

$(2.5\cdot10^{-10})\cdot(7\cdot10^{-6})=1.75\cdot10\cdot10^{-16}=1.75\cdot10^{-15}$

Answer: $1.75\cdot10^{-15}$
