Answer:

360 cm^2.

Step-by-step explanation:

Area of the base = 10*10 = 100 cm^2.

We find the slant height of the sides using Pythagoras:

h = sqrt ( 12^2 + 5^2)

h = sqrt 169

h = 13.

Area of the triangular sides = 4 * 1/2 * 10* 13

= 260 cm^2

So the total surface area = 100 + 260

= 360 cm^2.

A train travels 95 kilometers in 1 hours, and then 97 kilometers in 1 hours. What is its average speed?

aleksandrvk [35]

Average speed is given by [Total Distance] ÷ [Total Time]

Average speed = $\frac{95+97}{1+1} = \frac{192}{2}=96$ km/hour

Please help me. I'm stupid.

Gwar [14]

Answer:

$\displaystyle 36\:units$

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100$
