Answer:

The area of the triangle is 13.5 square units

Step-by-step explanation:

The easiest way to find the area of of a triangle is to find the area of rectangle surrounding it, and divide by two.

In this case, we can use the bottom line and the distance from that to the top point as the side lengths of our "rectangle"

The bottom line has a length of 9, and the distance from that line to the top point is 3. We can say then that the area of the triangle is half of three times nine:

3 × 9 ÷ 2 = 3 × 4.5 = 13.5

So the total area of the triangle is 13.5 square units

4. At Eagle Rock High School, the probability that a student takes theatre and choir is 0.052.

Answer:

Step-by-step explanation:

Conditional probability is:

P(A given B) = P(A and B) / P(B)

Here, P(A and B) = 0.052 and P(B) = 0.17:

P(A given B) = 0.052 / 0.17

P(A given B) = 0.306

The area of a circle is 28.26 square meters. What is the circle's diameter?

ikadub [295]

Answer: area for circle is πr² so πr² =28.26 and we can sub 3.14 as pi

3.14*r²=28.26 we can divide by 3.14 to get r² on it's own

r²=28.26/3.14

then we root both sides to get r on it's own

28.26/3.14=9 √9=3

and the diameter is double the radius 3*2=6 so the diameter is 6

Pls pls pls pls help

Answer:

see below

Step-by-step explanation:

A. Reflection across the y-axis replaces each x coordinate with its opposite.

B. Rotation 90° CW does the transformation (x, y) ⇒ (y, -x)

C. This is a translation left 2 units.

D. Rotation 90° CCW does the transformation (x, y) ⇒ (-y, x)

E. This is a translation left 7 and down 2.

In the attached graphs, we have identified a point that is a corresponding point on each figure. This is so you can see how the various transformations move it and the rest of the figure in relation to it. 90° arcs are shown so you can see the rotations more easily.

The figures are labeled and color coded in accordance with the problem statement.
