Step-by-step explanation:
she wrote it to solve the total amount spent on both T shirt.
30+6x=20+8x-8x
30+6x-8x=20
30-30-2x=20
-2x=20-30
-2x/-2=-10/-2
<u>x=5</u>
Answer:
(5sqrt(2), 45 deg)
(-5sqrt(2), 225 deg)
Step-by-step explanation:
(x,y)=(5,5)
So theta=arctan(5/5)=arctan(1)=45 degrees
Now r! r=sqrt(x^2+y^2)=sqrt(5^2+5^2)=sqrt(50)=sqrt(25)sqrt(2)=5sqrt(2)
So one polar point is (5sqrt(2) , 45 degrees)
Now if we do 180+45=225 degrees... this puts us in the 3rd quadrant... to get back to quadrant 1 we just take the opposite of our r
so another point is (-5sqrt(2) , 225 degrees)
When is cos (x) = 0? <em>at 90° (aka π/2)</em>
Answer: 
The question is incomplete. The complete question is as follows.
Juan, Carlos and Maria went to the museum. The entrance ticket cost $5 per person, but, as they are students, there is a discount of $1 per ticket. After, they bought: 3 combos of chicken and fries costing $4 each; 3 bottles of water costing $1 each; 3 vanilla cookies costing $1 each; How much money each student paid if they divided the costs in equal amount?
Answer: $10
Step-by-step explanation: As each students split the bill in equal parts, to find how much they spent, we can calculate how much one of the three spent.
For ticket: 5 - 1 (because of the students discount) = $4
Each combo of chicken and fries cost $4, so: combo = $4
Each bottle of water costs $1, so: water = $1
and each vanilla cookie costs $1: cookie = $1
Total spent is:
T = 4+4+1+1
T = 10
Each student spent a total of $10 for this outing.
