Answer:

1. y = 6x + 8

2. 4 hours.

Step-by-step explanation:

x is each hour of work.

y is the total that Carolina is paid.

y = mx + b

32 = 6(x) + 8

<em>Subtract 8 from both sides.</em>

6x = 32 - 8

6x = 24

<em>Divide both sides by 6.</em>

x = 4

Carolina is works 4 hours to be paid 32.

Answer:

F(t) = 8 + 6(t)

Step-by-step explanation:

6*4 = 24

32-24 = 8

so her initial fee is $8

so function is:

F(t) = 8 + 6(t)

A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting i
dedylja [7]

Answer: C.  \dfrac{1}{3}

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = \dfrac{\text{favorable outcomes}}{\text{total outcomes}}

Probability of selecting a purple ball (second pick)= \dfrac{4}{12}

=\dfrac{1}{3}

The required probability =\dfrac{1}{3}, so C is correct option.

Let an integer be chosen at random from the integers 1 to 30 inclusive. Find the probability that the integer chosen is not even

Exactly half of these integers are odd (1, 3, 5, ..., 29) so the probability of selecting an odd number is \dfrac12.

An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 4 ft long with a diameter of 2.2 ft. S
gavmur [86]

Answer:

8\:\mathrm{minutes}

Step-by-step explanation:

The volume of a cylinder is given as:

r^2\cdot\pi\cdot h

Since the diameter is 2.2, the radius is \frac{2.2}{2}=1.1.

Therefore, the volume of this cylinder is:

1.1^2\cdot 3.14\cdot 4=15.1976\:\mathrm{ft^3}, using \pi=3.14 as requested in the problem.

Since the tank is emptied at a constant rate of 1.5\:\mathrm{ft^3\:per\:minute}, it will take

\frac{15.1976}{1.5}=7.5988=\fbox{$8\:\mathrm{minutes}$} to empty the tank.

What multiplies to be 280 and adds to be negative 36
photoshop1234 [79]
The two numbers are -18+ 2√(11) and -18 -2√(11).

-18+ 2√(11)+ [-18 -2√(11)]= -36
[-18+ 2√(11)]* [-18 -2√(11)]= 280.

Hope this helps~
