Answer:

1. 2700 ÷ 15 = 180. However, this is theoretical and assumes that no ribbon is destroyed when a cut is made.

2. The area of the land in square meters is 412, 500.

500 pesos is the price per square meter of the land.

Step-by-step explanation:

Word Problem

Since the first question asks for the area of the land in "square meter", we need to convert 0.75 kilometers to meters.

Steps in Converting the Units

Choose the appropriate conversion factors.

Multiply the given unit measure by the conversion factor.

Simplify the product.

\begin{gathered}0.75\:\text{km}\times\left(\begin{aligned}\text{Conversion}\\\text{Factor}\end{aligned}\right)\end{gathered}

0.75km×(

Conversion

Factor

)

Now, we know that 1 km = 1000 m, so our conversion factor should be \frac{1000\:\text{m}}{1\:\text{km}}

1km

1000m

. We intended to have a unit km in the denominator so that during the multiplication process, we can cancel the km unit.

\begin{gathered}\begin{aligned}0.75\:\text{km}\times\left(\frac{1000\:\text{m}}{1\:\text{km}}\right)&=0.75\times 1000\:\text{m}\\&=750\:\text{m}\end{aligned}\end{gathered}

0.75km×(

1km

1000m

)

=0.75×1000m

=750m

The area of a rectangle is given by the formula, A = l \times wA=l×w . So, to solve for the area, substitute the value of l=750\:\text{m}l=750m and w=550\:\text{m}w=550m into the area formula then simplify.

\begin{gathered}\begin{aligned}A&=l\times w\\&=750\:\text{m}\times550\:\text{m}\\&=412, 500\:\text{m}^2\end{aligned}\end{gathered}

A

=l×w

=750m×550m

=412,500m

2

So, the area of the rectangular lot is 412, 500 square meters.

If he is selling the whole land for 206, 250, 000 pesos, then to solve the price per square meter is given by the formula, C=\frac{\text{Price of the whole land}}{\text{Area of the whole land}}C=

Area of the whole land

Price of the whole land

.

So, to solve for the price per square meter, substitute the price of the whole land and the area of the whole land into the equation.

\begin{gathered}\begin{aligned}C&=\frac{206,250,000}{412,500}\\&\boxed{C=500}\end{aligned}\end{gathered}

C

=

412,500

206,250,000

C=500

3. 1.184 liters

4. The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.

5. 2.5 kg to grams is 2500

(n kg x 1000 = n g)

2500 ÷ 250 = 10

so you will need 10 of 250 grams to get 2.5 k

6. 0.6 kilograms of powder milk can produce 60 cups of milk.

14.22 liters is 60 cups of milk.

7. 10 hours per day

B. dunno about this 29 hr and 45 min
