Answer:

Step-by-step explanation:

You get 2640 and double it which is 5280 and then do 2640/5280 which is 0.5, that is the amount of miles in 2640 feet. So the answer is 0.5 mph which is C

Raymond wants to make a box that has a volume of 360 cubic inches. He wants the height to be 10 inches and the other two dimensi

agasfer [191]

The volume of the box is l*w*h, or l*w*10, and also the volume is 360. so, 10lw=360, meaning l*w=36, so we are looking for whole number factors of 36.
length: 1 2 3 4 6 9 12 18 36width:36 18 12 9 6 4 3 2 1
there are a total of 9 possible ways to make the base of the box so your answer would be 9

12. Solve the following inequality.

Feliz [49]

Answer:

C. The solution set is {x|x < 6}.

Step-by-step explanation:

Given :

7x + 4 < 46

Subtract 4 from both sides.

7x + 4 - 4 < 46 - 4
7x < 42

Divide 7 from both sides.

7x/7 < 42/7
x < 6

C. The solution set is {x|x < 6}.

Suppose the system below is consistent for all possible values of f and g. What can you say about the coefficients c and d? Just

morpeh [17]

Answer:

The answer is " $d \neq 3c,$ f and g are arbitrary".

Step-by-step explanation:

The matrix of the device is increased

$\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right]$

Reduce the echelon row matrix

$\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right] \\\\R_1 \leftrightarrow R_2 \\\\\frac{R_2 -1}{C R_1 \to R_2} \sim \left[\begin{array}{ccc} c&d&g\\ 0 & \frac{3c-d}{c}& \frac{cf-g}{c}\\ \end{array}\right]$

Therefore, if 3c $\neq$ 0 is d $\neq$ 3c, the device is valid. Therefore d $\neq$ are arbitrary 3c, g and f.

What is the length of line segment YX? 8 units 8 StartRoot 3 EndRoot units 12 units 12 StartRoot 3 EndRoot units.

timurjin [86]

Length of line segment YX is distance of both the ends of it. The length of line segment YX is $8\sqrt{3}$ units.

<h3>What is length of a line segment?</h3>

The length of a line segment is the measurement of the distance of both the ends of it.

Given information-

In the rectangle $YVWX$ the length of line line segment YV is 24 units.

The rectangle $YVWX$ is shown in the image below.

The angle given in the figure is,

$m\angle X=30\\m\angle W=90\\m\angle V=60$

Now in the figure of rectangle shown below, the triangle XWV is the right angle triangle.

In this right angle triangle the tan of angle is the ratio perpendicular to the base. thus,

$\tan 60=\dfrac{24}{VW}\\\sqrt{3}=\dfrac{24}{VW}\\VW=8\sqrt{3}$

As the opposite side of a rectangle are equal. Thus, the length of line segment is VW is equal to the length of the line segment YX. Therefore,

$YX=VW=8\sqrt{3}$
