Answer:
B) 12 hours
Explanation
Max can read 150 words per minute. 350 words per page divided by 150 is 2.333, so max can read 1 page in around 2 minutes. There are 310 pages. 2.333 * 310 is around 723. 723 minutes converted to hours is 12 hours. Boom. Done.
Answer:
(-1,2)
Step-by-step explanation:
1. substitute y=2x+4 in for y
2. solve 2x+4=5x+7 and you get x=-1
3. sub in -1 for x and solve
4. y=2
5. solution is (-1,2)
Answer:
For 0° ≤ x ≤ 360° we have:
x=0, 360, arccos(1/6), -arccos(1/6)
Step-by-step explanation:
Replace cos(x) by y
6y²-7y+1=0
6y²-6y-y+1=0
6y(y-1) -(y-1)=0
(y-1)(6y-1)=0
Roots:
y=1, cos(x)=1, x=0 and 360
y=1/6, cos(x)=1/6, x=arccos(1/6) and x=-arccos(1/6)

Step-by-step explanation:
Givens
Wednesday is taller than Monday or Tuesday.
Thursday and Friday were more than double Wedensday
Solution
Graph A: Monday + Tuesday looks like they could add to Wednesday.
Further Thursday and Friday are both more than Wednesday.
Graph A is you answer.
Graph B: Thursday does not look like double Wednesday. B is not the answer.
Graph C:: Monday and Tuesday exceeded Wednesday. Graph C is not right.
Graph D: Just wrong. Thursday and Friday and not double Wednesday.
Okay so start by finding the cost of the sandwich and the drink together. Once you have that number you need to find what 7% (or 0.07) or that number is. HINT it should be less than $0.50. Add this 7% to your sandwich-drink total and ta-da!!!
