The probability of randomly selecting a purple marble first is a 1/2 chance or .50 in decimal form. If we take that marble out then randomly getting a blue marble would be 5/39 chance or 0.13 chance.

Write and solve an equation to find the value of x and a missing angle in the triangle below.
Oksi-84 [34.3K]

Answer:

angle UTS +TSU =TUV

THEREFORE, 81 + 12X =24X+9

THEREFORE, 81 - 9 = 24X - 12X

THEREFORE, 72 = 12X

THEREFORE, 72/12 =X

THEREFORE, x = 6

THEREFORE, ANGLE TSU = 12 * X

= 12 *6

= 72

YOUR ANSWER IS

X=6

TSU=72

juin [17]

Answer: Profit = 0.4x - 25

Step-by-step explanation:

Let x represent the number of cookies that he makes and sells.

Profit = Revenue - total cost

Manny purchased a set of cookie cutters for $25. The ingredients for his cookies will cost him $0.35 per Cookie. This means that his total cost of producing x cookies is

0.35x + 25

He plans to sell cookies for $0.75 each. This means that the revenue generated from selling x cookies is 0.75x

Therefore, the equation giving Manny's total profit per cookie as a function of the number of cookies he makes is

Profit = 0.75x - (0.35x + 25)

Profit = 0.75x - 0.35x - 25

Profit = 0.4x - 25

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

A.)

The percentile ranking of Tine is,

Tina's Ranking = [1 - (54/300)] × 100% = 82%

Tina's soster Ranking = [1 - (23/175)] × 100% = 86.85%
