11:30 and 1:00
assuming that it is
11:30 AM to 1:00 PM and not 11:30 AM to 1:00 AM

11:30 to 1:00 cannot be directly counted
the hours go like this
1,2,3,4,5,6,7,8,9,10,11,12=AM
then after 12AM then
1,2,3,4,5,6,7,8,9,10,11,2=PM

60 minutes in 1 hour so
11:30=11 hours and 30 mins
how far to 12 AM?
12 AM=12 hours=11 hours and 60 minutes
11 hours and 60 minutes-(11 hours and 30 mins)=30 minutes

then from 12 AM to 1 PM=1 hour so
time total difference is 1 hour and 30 minutes

his class lasts for 1 hour and 30 minutes because all you have to do is count how long the hours are then subtract 30 minutes and there you go 1 hour and 30 minutes.

13. Write the equation of a horizontal line that passes through the point (3, -3).

Step2247 [10]

Answer:

O y = -3

Step-by-step explanation:

The line is horizontal.

x = -3 and x = 3 are vertical lines, so they are incorrect.

The line passes through (3, -3).

(x , y)

Put y as -3.

y = 3

(-3) = 3

Line y = 3 is incorrect.

(-3) = -3

Line y = -3 is correct.

Which equation is perpendicular to 3x - y = 9 and goes through the point (6,6)

Lelechka [254]

Answer:

y = - $\frac{1}{3}$ x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x - y = 9 into this form by subtracting 3x from both sides

- y = - 3x + 9 ( divide all terms by - 1 )

y = 3x - 9 ← in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{3}$ , thus

y = - $\frac{1}{3}$ x + c ← is the partial equation

To find c substitute (6, 6) into the partial equation

6 = - 2 + c ⇒ c = 6 + 2 = 8

y = - $\frac{1}{3}$ x + 8 ← equation of perpendicular line

A) x= all real #s B) x>0 C) x=5 D) x=12

sashaice [31]

Answer:

Set of all real numbers

Step-by-step explanation:

When we talk of domain, we mean the possible values of x that the equation can take without being undefined

So x-values that makes the equation defined are the domain of the graph

From the diagram, we can see that the graph extends from negative infinity to positive infinity

What this mean is that the possible values here come from the top right and extends to the left

So this means that the range of possible values are the set of all real numbers

Jodi built a rectangular sandbox for her daughter. The sandboxmeasures6 feet by 5feet by 1.2 feet. Jodi purchases 20cubic feet o

Mamont248 [21]

For this case, the first thing to do is to model the rectangular sandbox as a rectangular prism.

The volume of the prism is given by:

$V = w * l * h$

Where,

w: width
l: length
h: height

Therefore, replacing values we have:

$V = 6 * 5 * 1.2\\V = 36 ft ^ 3$

We observed that:

$36 ft ^ 3> 20 ft ^ 3$

Therefore, the sandbox is not completely filled.

Answer:

the sandbox will hold $36 ft ^ 3$ of sand

Jodi purchase is not enough sand to fill the sandbox to the top.

$36 ft ^ 3> 20 ft ^ 3$
