Answer:

2.33 hours

Step-by-step explanation:

Given

Veteran Tutor

Charges = \$15 --- first session

Hourly\ Rate = \$60

College Graduate

Charges = \$45 --- first session

Hourly\ Rate = \$50

Required

Determine the number of hours they earn the same amount

Represent the hours with x

First, we need to calculate the total charges for the veteran tutor for x hours;

Total = 15 + 60x

Next, we need to calculate the total charges for the college graduate tutor for x hours;

Total = 45x + 50

For them to earn the same amount, we have:

15 + 60x = 45x + 50

Solving for x

60x - 45x = 50 - 15

15x = 35

Divide through by 15

x = \frac{35}{15}

x = 2.33\ hours

zzz [600]

Answer:

The probability is 0.25

Step-by-step explanation:

Here is a probability question.

We want to know the probability of picking a card which is in the spades suit.

Now, what we know is that there are a total of 52 cards and we have 4 suites.

Each suite have equal number of cards. So definitely the number of cards in the spades suit will be 52/4 = 13 cards

Thus, the probability of picking any card in the spades suit = number of cards in the spades suit/ Total number of cards in the deck

Mathematically that would be 13/52 = 1/4 = 0.25

All factors of x cubed minus 6x squared plus 11x minus 6
miv72 [106K]

Answer:

Step-by-step explanation:

x³-6x²+11x-6

put x=1

1³-6×1²+11×1-6=1-6=11-6=0

by synthetic division

1| 1 -6  11   -6

|     1  -5    6

|----------------

| 1  -5  6 |0

x²-5x+6=0

x²-2x-3x+6=0

x(x-2)-3(x-2)=0

(x-2)(x-3)=0

x=1

x-1=0

so x³-6x²+11x-6=(x-1)(x-2)(x-3)
