Answer:
48
Step-by-step explanation:
The square pyramid has exactly the same four triangles.
In order to find the whole surface area, we must find the area of one of the triangles and multiply them by 4.
Surface area of square pyramid =
Where we know that b = 4 and h = 6.
Substituting into the formula should give us the answer 48.
<em><u>Solution:</u></em>
Given that,
David goes into a candy store with $5.00
Total amount with David = $ 5
He buys 9 peppermints for $0.15 each
And some sour candies. each sour candy costs $0.25
The equation is:
Let the number of sour candies bought be "x"
Then,
Remaining amount after buying pepper mint =
Each sour candy cost $0.25
<em><u>Now the number of sour candies bought is:</u></em>
x = 14.6
Thus david can buy 14 sour candies
<em><u>Thus the equation that will match the story problem is:</u></em>
Where, "x" means number of sour candies bought
