Answer:

So it will take 6 minutes to ring up 72 items.

Step-by-step explanation:

Well this seems pretty simple just have to reads the question and know what to find.

So what we know :

A cashier can ring up 12 items per minute

So :

1 minute = 12 Minutes

And we have to find :

How long for 72 items

So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.

So :

72 / 12

=

6

So it will take 6 minutes to ring up 72 items.

I hope this helps!

If you have any questions or concerns feel free to message me or comment. :)

Julie went to visit her aunt and uncle for the weekend. She took the following clothes: two pairs of slacks – one brown, one bla
kaheart [24]

Answer: 0.25

Step-by-step explanation:

The data we have is:

Slacks: one brown, one black.

Sweaters: one tan, one red, one white.

Shirts: one white, one gray.

If the clothes are selected at random, then the probability that Julie will wear brown slacks is equal to the number of brown slacks, divided the total number of slacks.

We have 1 brown slack and 2 slacks in total, so the probability is:

p1 = 1/2 = 0.5

We do the same for the white shirt, we have 2 shirts and one is white, so the probability is:

p2 = 1/2 = 0.5

And we do not have any condition in the sweater, so we can ignore that selection.

Then the probability of both events happening at the same time (that Julie will wear brown slacks and a white shirt) is equal to the product of the individual probabilities: P = p1*p2 = 0.5*0.5 = 0.25

What is a slope of a line represented by the equation 2x + 3y equals -12
Verizon [17]

Answer:

M = -2/3

Step-by-step explanation:

2x + 3y = -12 (subtract 2x from both sides)

3y= -2x -12 (divide everything by 3)

Y = -2/3x - 4


M= -2/3

Simplify the expression. 12x^-6 y^10 times 3x^7 y
Vlada [557]

We need to simplify the expression:

12x^{-6}y^{10} \times (3x^{7}y)

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,  

12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)

On simplifying the above expression we get:

36\times x^{(-6+7)}\times y^{(10+1)}

=36 \times x^{1}\times y^{11}

=36 \times x \times y^{11}

=36xy^{11}

So the simplified form of the expression 12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}.

Using graph paper, determine the line described by the given point and slope. Click to show the correct graph below.
gayaneshka [121]

When you know the coordinates of a point and the slope of a line, you can use the formula

y-y_0=m(x-x_0)

in your case, (x_0,y_0)=(0,0) and m=\frac{2}{3}, so you have

y-0=\dfrac{2}{3}(x-0) \iff y=\dfrac{2}{3}x
