Answer:

2.25 inch

Step-by-step explanation:

The current volume of box :

Volume = height * width * depth

Volume = 12 * 9 * 2

Volume = 216 in³

New dimension :

Height and volume are the same

Width = 9 - 1 = 8

Depth = x

Volume = height * width * depth

216 = 12 * 8 * x

216 = 96x

x = 216 / 96

x = 2.25 inch

Answer:

d = 637 ft below the surface

Step-by-step explanation:

Given

P = 14 + [tex]\frac{6}{13}[/tex] d

To find d when P = 308, then

14 + [tex]\frac{6}{13}[/tex] d = 308 ( subtract 14 from both sides )

[tex]\frac{6}{13}[/tex] d = 294 ( multiply by 13 to clear the fraction )

6d = 3822 ( divide both sides by 6 )

d = 637 ft

Answer:

Step-by-step explanation:

[tex]P=14+\dfrac6{13}d\\\\\\P=308\,,\qquad\qquad d=??\\\\\\308=14+\dfrac6{13}d\\\\ 308-14=\dfrac6{13}d\\\\294=\dfrac6{13}d\\\\d=294:\frac6{13}\\\\ d=294\cdot\frac{13}6\\\\d=637\,ft[/tex]

Given:

The diagram of two right triangles.

To find:

The value of d and a.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

(a) In first triangle,

[tex]\tan 60^\circ=\dfrac{d}{4}[/tex]

[tex]\sqrt{3}=\dfrac{d}{4}[/tex]

[tex]4\sqrt{3}=d[/tex]

Therefore, [tex]d=4\sqrt{3}[/tex].

(b) In second triangle,

[tex]\sin 45^\circ=\dfrac{a}{2}[/tex]

[tex]\dfrac{1}{\sqrt{2}}=\dfrac{a}{2}[/tex]

[tex]\dfrac{2}{\sqrt{2}}=a[/tex]

[tex]\sqrt{2}=a[/tex]

Therefore, [tex]a=\sqrt{2}[/tex].

Answer:

(2/3, 13/3)    (Exactly one solution)

Step-by-step explanation:

Write these equations in a column:

 x+y=5

2x-y=-3

Note that we can eliminate y immediately by adding these two equations together. We get:

3x = 2, so that x = 2/3.

Substituting 2/3 for x in the first equation, we get:

2/3 + y = 5.  Clear out fractions by multiplying all three terms by 3:

2 + 3y = 15, or 3y = 13.  Then y = 13/3, and the solution is

(2/3, 13/3)      There is exactly one solution.

Step-by-step explanation:

5.75x10=57.50

57.5+11.5=69(nice)

69+5.75= 74.75

74.75+5.75=80.5

80.5+5.75= 86.25

86.25+5.75=92

basically this formula should help

Step-by-step explanation:

Answer:

 translate the graph 5 units left and down 2 units

Step-by-step explanation:

To translate the function f(x) by an amount h units right and k units up, make the transformation ...

 g(x) = f(x -h) +k

Comparing this to your equation,

 g(x) = f(x +5) -2

we see that the translation is h = -5, k = -2.

The graph of f(x) is translated 5 units left and 2 units down to make the graph of g(x).

Triangle inequality theorem:

Combined the inequality is:

The length of the third side can't be 2 or smaller or 18 or greater

Answer:

5.618773 m2

I hope that this is the answer.

Answer:

answer is 60.48 m squared

Step-by-step explanation:

use the formula

a=1/2(b1+b2)h

a=1/2(15.8+6.6)h

a=1/2(22.4*5.4)

a=1/2(120.96)

a=120.96/2

a=60.48m

Answer:

Least to greatest: 2, 3, 1

Step-by-step explanation:

Square root of 8 over 2 is about 1.41 which makes it the least value

2 is obviously equal to 2 which puts it in the middle

Square root of 7 is about 2.64 which makes it the greatest value

Answer:

neither a function or a relation

Step-by-step explanation:

The graph does not pass the vertical line test, thus not a function.

In the graph, x-coordinates are not related to y-coordinates through a relation, thus not a relation.

Answer:

Square; x=2; y=1

Step-by-step explanation:

Being that the following quaderlateral has equal sides and angles equal to 90 degrees each, it would be classified as a square.

Now, knowing that they have all equal sides, you could say that

1). 5x-4=3x

as well as

2).2y+4=5y+1

Now, solve for each of the variables:

1). 5x-4=3x

    (Minus 3x from both sides and add 4 to both sides)

     2x=4

     (Divide by 2)

     x=2

2). 2y+4=5y+1

    (Minus 5y from both sides and minus 4 to both sides)

   -3y=-3

   (Divide by -3)

      y=1

Hope it helped! (:

Answer: 5 + 0.5m

Step-by-step explanation:

Let the number of miles be represented by m.

Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:

= 5 + 0.5m

For example if the number of miles taken is 100miles, the amount charged will be:

= 5 + 0.5m

= 5 + 0.5(100)

= 5 + 50

= $55

Answer:

The maximum height of the rocket is about 391.1 feet.

Step-by-step explanation:

The height of the rocket y in feet x seconds after launch is modeled by the equation:

[tex]y=-16x^2+125x+147[/tex]

We want to find the maximum height reached by the rocket.

Since this is a quadratic equation, the maximum height occurs at the vertex. The vertex of a quadratic is given by:

[tex]\displaystyle \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In this case, a = -16, b = 125, and c = 147.

Thus, the x-coordinate of our vertex is:

[tex]\displaystyle x=-\frac{125}{2(-16)}=\frac{125}{32}[/tex]

To find the maximum height, we will substitute this value back in. So:

[tex]\displaystyle y_{\text{max}}=-16\left(\frac{125}{35}\right)^2+125\left(\frac{125}{32}\right)+147\approx391.1\text{ feet}[/tex]

The maximum height of the rocket is about 391.1 feet.
