Mai has a rectangular poster. The poster is 1.6 meters long and 1.2 meters wide.
dangina [55]

Answer:

19,200 cm^2.

Step-by-step explanation:

The area = 1.2 * 1.6 = 1.92 m^2.

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.

PLEASE HELP Find the value of x.<br> X<br> 15<br> 12
zlopas [31]

Answer: x = 9

Step-by-Step Solution:

Hypotenuse = 15 units

Base = 12 units

Altitude = x units

Using Pythagoras Theorem,

=> Hypotenuse^2 = Base^2 + Altitude^2

(15)^2 = (12)^2 + x^2

225 = 144 + x^2

225 - 144 = x^2

81 = x^2

x^2 = 81

x = √81

=> x = 9

Therefore, Altitude = 9 units

The square of a whole number 'n' lies between 80 and 150. Find all possible values for 'n'.
pychu [463]
The square of a whole number n lies between 80 and 150, so n lies between √80 and √150.

\sqrt{80} \approx 8.9 \\&#10;\sqrt{150} \approx 12.2

n is a whole number and lies between 8.9 and 12.2, so n can be 9, 10, 11, or 12.

The possible values for n are 9, 10, 11, and 12.
