evaluate: 16^1/2 x 2^-3

Answers

Answer 1

Answer:

64

Step-by-step explanation:

16^1

---------------------- = 64

2 x 2 - ^3

Apply exponent rule

16^1 = 16

= 16

------------------

2x2 - ^3

16 = 2x 8

2 x 8

-----------

2 x 2 - ^3

Cancel the common factor <2>

8

---------

2-^3

Factor the number 8 = 2^3

2^3

----------

2-^3

Apply exponent rule.

= 2^3 - (-3) = 6

3- (-3) = 6

= 2^6

2^6 = 64

64 is the answer

Answer 2

Answer:

0.5

Step-by-step explanation:

[tex] {16}^{ \frac{1}{2} } \times 2 {}^{ - 3} [/tex]

[tex] \sqrt{16} \times \frac{1}{{2}^{3} } [/tex]

To rent a certain meeting room, a college charges a reservation fee of $34 and an additional fee of $9.90 and hour. The math club wants to spend less than $123.10 on renting the meeting room. What are the possible amounts of time that they could rent the meeting room? use t for the number of hours the meeting room is rented

Answers

Answer:

9 hours

Step-by-step explanation:

Firstly,

Minus $123.10 with $34

123.10-34

= 89.10

(bcuz $34 is the reservation fee)

Secondly,

Divide $89.10 with $9.90 to determine the hours

t = 89.10/9.90

= 9

Last answer = 9 hours

There are 133 students at a small school and 23 of them are freshmen. What fraction of the students are freshmen?

Answers

Answer:

23/133

Step-by-step explanation:

If your total is 133, that would become your denominator, your numerator is how many students of those are freshman in which this case is 23.

The total number of freshmen in the school is 23/133


The number of students in the small school is 133


23 out of the 133 students are freshmen


Therefore the fraction of freshmen in the school can be calculated by dividing 23 by 133


Fraction of freshmen is 23/133

2xy-yz=8 solve for z

Answers

The answer is: z = -8/y + 2x

The solution of the equation in terms of z will be; z = 2x - 8/y

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given the equation as;

2xy-yz=8

Now we have to solve for z;

2xy-yz=8

-yz = 8 - 2xy

Then divide by y on both sides;

z = 2xy/y - 8 / y

z = 2x - 8/y

Step-by-step explanation:

The mean is the average of a data set.  Given the values, 2, 9, 10, 12, 12:

Add all the numbers in the data set, and divide its sum by the number of items in the set:

Mean = [tex]\frac{2+9+10+12+12}{5}[/tex] =  [tex]\frac{45}{5}[/tex] = 9

Write an equation of the line that passes through (0,4) and (0,-3).

Answers

Answer:

It is a vertical line at x = 0

Step-by-step explanation:

An equation of a line in a slope-intercept form is y=mx+b

So with the coordinates given, we must find the slope (m), and the y-intercept (b).

In order to find the slope using these coordinates,

we have to use the formula (y2-y1)/(x2-x2).

So the slope would be -3 - 4 / 0.

Because the denominator is 0, the slope would be undefined.

It is easier to see the equation/graph by graphing the coordinates on the coordinate plane. You will see that it is a straight vertical line down x=0.

Hello there! :)

We can use the formula:

[tex]\frac{y2-y1}{x2-x1} \\[/tex]

First, let's take a look at the x-coordinates. They are the same, aren't they?

If the x-coordinates are the same, then the slope is undefined.

Put the x-coordinates into the formula. It turns out that we divide by 0, and division by 0 is undefined.

Hope this helps!
