Answer:

C. 336 cm²

Step-by-step explanation:

Area formulas:

Area of a right triangle: a × b ÷ 2

Area of rectangle: length × width

-----------------------------------------------------------------------------------------------------------------

In this figure, there is a rectangle with a width of 12 and a height of 6.

; the area of the rectangle is 72 cm².

There are two right triangles with legs of 6 and 8.

There are two right triangles so..

The area of a single triangle is 24 cm²; the area of the triangles combined is 48 cm.

There is a rectangle in the middle with a width of 8 and a height of 12.

The area of the rectangle is 96 cm².

Lastly, there is a rectangle with a width of 10 and a height of 12.

The area of the rectangle is 120 cm².

Now, add the areas of every shape to find your answer.

T = 3U / E solve for U

Rashid [163]

<span>T = 3U / E solve for U

3U = T * E
U = (</span>T * E)/3
U = 1/3(TE)

This Venn diagram shows the pizza topping preferences for 9 students. Let event A = The student likes pepperoni. Let event B = T

Lelechka [254]

Answer:

$P(A\ or\ B)=\frac{7}{9}$

Step-by-step explanation:

We need to use the formula to calculate the probability of (A or B) where

A=Probability a student likes pepperoni

B=Probability a student likes olive

A and B =Probability a student likes both toppings in a pizza

A or B =Probability a student likes pepperoni or olive (and maybe both), a non-exclusive or

The formula is

$P(A\ or\ B)=P(A)+P(B)-P(A\ and\ B)$

Since 6 students like pepperoni out of 9:

$P(A) = \frac{6}{9}$

Since 4 students like olive out of 9:

$P(B) = \frac{4}{9}$

Since 3 students like both toppings out of 9

$P(A\ and\ B) = \frac{3}{9}$

Then we have

$P(A\ or\ B)=\frac{6}{9}+\frac{4}{9}-\frac{3}{9}$

$P(A\ or\ B)=\frac{7}{9}$
