The cost is 3 times the amount of the apples.
C = 3a
<h3>
Answer: Choice B. 5*sqrt(10)</h3>
==========================================================
Explanation:
It helps to add point labels. Let's place point A at the very top point of the triangle. Then point B will be at the 90 degree angle. Point C is the far left point. Lastly, point D is on segment BC such that DC = 3.
Since BC = 8 and CA = 17, we can use the pythagorean theorem to get...
(AB)^2 + (BC)^2 = (AC)^2
(AB)^2 + (8)^2 = (17)^2
(AB)^2 + 64 = 289
(AB)^2 = 289-64
(AB)^2 = 225
AB = sqrt(225)
AB = 15
Now focus on triangle ABD and apply the pythagorean theorem again to find side AD
(AB)^2 + (BD)^2 = (AD)^2
AD = sqrt( (AB)^2 + (BD)^2 )
AD = sqrt( (AB)^2 + (BC-CD)^2 )
AD = sqrt( (15)^2 + (8-3)^2 )
AD = sqrt(250)
AD = sqrt(25*10)
AD = sqrt(25)*sqrt(10)
AD = 5*sqrt(10) .... answer is choice B
To start off answering this, you need to look at the first sentence. A number divided by 3 is 4 more than -11. That means that you can start off by using what you are given and bring it down to A number divided by 3 is -7. So -7*3=-21. I don't understand the rest of your question, but this is what I have come up with based on what I have been given.
let's firstly convert the mixed fraction to improper fraction.
