Answer:

Omar

Step-by-step explanation:

to find the base, which i am to assume they want to find the triangle base based on the formula they are using,

you should multiply base * height, then divide by 2, since it is a triangle, you not solving for a rectangle.

dividing by 2 and multiplying by 1/2 is the same thing!

so,

1/2 (7* 24) is the right answer to finding the base!

Kari looked at he direct base of 7*28, however, that shape is actually a rectangle... so Kari is wrong because he multiplied that dimension by 1/2, which is the formula for a triangle.

Omar is correct because he chose the dimensions of a triangle, and properly used the triangle formula!

i hope this helped you out!

stay safe!

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?. a. using a paid
Paraphin [41]

<u>Answer</u>

c. buying it at a 10 percent discount without sales tax.


<u>Explanation</u>

We are going to compare the 3 choices and then determine the most cost effective.

<em>a. using a paid membership card to buy it at a 10 percent discount.</em>

10% of $100 = 10/100×100 = $10

cost = $100 - $10 = $90

On top of this $90 there is the charges of the membership card.

<em> b. buying it online at a 10 percent discount with a $5 shipping charge.</em>

100%-10% = 90%

90% of 100 = $90

Cost: $90 + $5 = $95

<em>c. buying it at a 10 percent discount without sales tax.</em>

100% - 10% = 90%

90/100 × 100 = $90. This is the must cost effective method since there is no other cost involved.
