As a reward for achieving their goals, all students in the ninth grade are invited to an ice cream party.

Arlecino [84]

Answer:

The expression that represents the estimated cost for the party is T=s×i

Step-by-step explanation:

1) We can get an estimated cost for the party by using the following expression:

T=s×i

where:

T: total cost of the ice cream party ($)

s: number of ninth students (person)

i: unit cost of ice cream ($/person)

2) If we choose the letter "s", it can take whole number values.

For example: s={1,2,3,4,5,...,25}

If we choose the letter "i", it can take rational values (sometimes the price of the items are not expresed as a whole number).

For example: s={1.25,2.50,3.00,4.75,5.00}

Your Turn: In the diagram, AB = 12, BX = 2.5, and DX = 5. Find CD. Show all work. *

rjkz [21]

<span>CD = 24 Triangles ABX and CDX are similar triangles. So the ratio of lengths between corresponding legs of the triangles will have the same value. You know that they're similar triangles because both of them are right triangles (so you know that one angle is the same in both) and that arc draw on both angles AXB and CXD indicate that those angles match as well. That tells you there's a second angle that's matching in both triangles, and because two of the angles match, you also know that the unmarked angle matches as well since all the angles in a triangle have to add up to 180 degrees. So you know that AB/CD = BX/DX. Substitute known values and you get AB/CD = BX/DX 12/CD = 2.5/5 Now solve for CD 12/CD = 2.5/5 12/CD = 1/2 24/CD = 1 24 = 1 * CD 24 = CD So the value of CD is 24.</span>

The number of radians in a 540540540-degree angle can be written as a\piaπa, pi, where aaa is a constant, what is the value of a

Art [367]

Using proportions, it is found that the value of a is of 3.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, a 180º angle has a measure of $\pi$ radians. What is the measure of a 540º angle? The <em>rule of three</em> is given by:
