Zepler [3.9K]

A fraction/probability is created by taking what we want and putting that over the total.

In this case, we want yellow out of the total number of marbles.

Yellow Marbles = 1

Total Marbles = 6 + 1 + 2 + 3 = 12

Probability/Fraction = 1 / 12

Hope this helps!

Sonja [21]

The correct answer for this question is this one: "Roughly 1.7 meters."

The height is 828 meters tall. The scale model is 1 meter is equal to 500 meters.

To the nearest tenth, Brody's model of the Burj Khalifa should be
= 828 / 500
= 1.656 meter
Roughly 1.7 meters.

Hope this helps answer your question and have a nice day ahead.

D = b^2 -4ac solve for a 2/3 (x-18y) = 6y solve for x

seropon [69]

Answer:

a = $\frac{b^2-d}{4c}$

x = 27y

Step-by-step explanation:

Order of Operations: BPEMDAS

Question 1

Step 1: Write out discriminant

d = b² - 4ac

Step 2: Subtract b² on both sides

d - b² = -4ac

Step 3: Divide both sides by -1

b² - d = 4ac

Step 4: Divide both sides by 4c

a = $\frac{b^2-d}{4c}$

Question 2

Step 1: Write out equation

2/3(x - 18y) = 6y

Step 2: Distribute parenthesis

2/3x - 12y = 6y

Step 3: Isolate x by adding 12y on both sides

2/3x = 18y

Step 4: Divide both sides by 2/3

x = 27y
