<em>C. 315 units^2</em>

Step-by-step explanation:

The formula for the area of a triangle is:

$A=\frac{1}{2}bh$

In this case, the base (b) will be 30 and the height (h) will be 21.

We can plug these numbers in the equation and make the 1/2 a .5.

$A=.5*30*21$

A = 315

<u>315 units^2</u>

Find the missing length of the triangle.

Hey there!

Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²

Here,

Base = 9 mm

Hypotenuse = 15 mm

Altitude = b

Hypotenuse² = Base² + Altitude ²

15² = 9² + b²

225 = 81 + b²

225 - 81 = b²

144 = b²

√144 = b

<u>1</u><u>2</u><u> </u><u>mm </u>= b

Hope it helps ya!

The low temperatures for 5 days was 5, -2, -11 ,0 and-3.What was the average low temperature for those days

Daniel [21]

Data:
Average (A): ?
Arithmetic mean (A.M) = 5, -2, -11, 0, -3sum of n numbers = 5

Solving:
$A = \frac{AM}{n} = \frac{5+(-2)+(-11)+0+(-3)}{5} = \frac{5-2-11-3}{5} = \frac{\diagup\!\!\!\!3-11-\diagup\!\!\!\!3}{5} = \frac{-11}{5} = - 2.2$

Answer:

<span>The average low temperature of these days is -2.2</span>
