Answer:
Area of triangle is 25.
Step-by-step explanation:
We have been given an isosceles right triangle
Isosceles triangle is the triangle having two sides equal.
Figure is shown in attachment
By Pythagoras theorem

AD is altitude which divides the triangle into two parts
DC=5 implies BC =10 since D equally divides BC
Let AC=a implies AB=a being Isosceles
On substituting the values in the Pythagoras theorem:




WE can find area of right triangle by considering height AB and AD
Area of triangle ABC is:
(1)

And other method of area of triangle is:
(2)
Equating (1) and (2) we get:



Using area of triangle is: 
Now, the area of triangle ABC=

Answer:
u = 156.25
Step-by-step explanation:
Step 1: Write equation
31.25 = u/5
Step 2: Solve for <em>u</em>
- Multiply both sides by 5: 156.25 = u
- Rewrite: u = 156.25
Step 3: Check
<em>Plug in u to verify it's a solution.</em>
31.25 = 156.25/5
31.25 = 31.25
Step-by-step explanation:
multiply
when 1 number is given and many is asked means multiply
Part 1
Add up the values in the table: 90+36+54+45+63+72 = 360
This means 360 total drinks were sold. Of that total, 54 were medium regular.
The percentage of medium regular is 54/360 = 0.15 = 15%
Apply this percentage to the 640 customers he plans to sell to
15% of 640 = 0.15*640 = 96
<h3>Answer: 96</h3>
============================================
Part 2
It sounds like your teacher wants you to find the probability of picking pink lemonade. The table says that 36 small, 45 medium, and 72 large pink lemonades were sold. That means 36+45+72 = 153 pink lemonades were sold out of the 360 total
153/360 = 0.425
Then go through each answer choice to note that 17/40 = 0.425 as well
Therefore, 153/360 = 17/40
Answer: 17/40
