A common number is 6 so divide 18 and 24 by 6. you get the total of 3/4 <span />
If cosΦ is lesser than zero (negative) it must be in quadrant 2 or 3 because cos is always positive in quadrants 1,4.
Answer:
see the explanation
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
Triangle BAE and CAD are similar -----> given problem
so
using proportionality
we have
substitute the values
solve for x
therefore
There is only one value of x that makes BAE and CAD triangles similar
The answer is 9. I notice you keep asking the same questions over and over again, all simple and trivial answers. Please either stop trolling or consult a parent or teacher to help you!
Complete question :
An ice cream stand uses the expression 2 + 0.5x2 to determine the cost (in dollars) of an ice cream cone that has x scoops of ice cream. How much does an ice cream cone with 5 scoops cost?
Answer:
$14.5
Step-by-step explanation:
Give the expression for the cost of ice cream cone with x scoops of ice cream :
Cost = 2 + 0.5x²
Cost of ice cream cone with 5 scoops of ice cream.
x = 5
Cost = 2 + 0.5(5²)
Cost = 2 + 0.5(25)
Cost = 2 + 12.5
Cost = 14.5
Hence, the cost of ice cream is $14.5
