Answer:

x=34

Step-by-step explanation:

2x =68

-----------             (68 divided by 2 is 34)

2        2

x=34

Answer:

the answer would be A. x=34

Step-by-step explanation:

to solve for x in this equation, you need to get x all by itself to do this, you need to remember that what you do to one side of the equation, you must do to the other. so:

we start with 2x=68, and to get rid of the 2 in front of the x, divide each side by 2.

2x/2=68/2

so now x is alone:

x=68/2

and now divide 68 by 2, which is 34.

so, x=34

Answer:

[tex]L_2 = 2\frac{2}{15}\ ft[/tex]

Step-by-step explanation:

Given

Original

[tex]Length(L_1) = 8\ in[/tex]

[tex]Height (H_1) = 15\ in[/tex]

New

[tex]Height (H_2) = 4\ ft[/tex]

Required

Determine the new length (L2)

Since the original photographs was blown up; the original and the new photographs would have the same ratio

i.e.

[tex]Ratio = L_1 : H_1[/tex]

and

[tex]Ratio = L_2 : H_2[/tex]

Equate both ratios

[tex]L_1 : H_1 = L_2 : H_2[/tex]

Rewrite as fraction

[tex]\frac{L_1}{H_1} = \frac{L_2}{H_2}[/tex]

Substitute values for L1, H1 and H2

[tex]\frac{8}{15} = \frac{L_2}{4}[/tex]

Multiply both sides by 4

[tex]4 * \frac{8}{15} = \frac{L_2}{4} * 4[/tex]

[tex]4 * \frac{8}{15} = L_2[/tex]

[tex]\frac{4 * 8}{15} = L_2[/tex]

[tex]\frac{32}{15} = L_2[/tex]

[tex]2\frac{2}{15} = L_2[/tex]

[tex]L_2 = 2\frac{2}{15}\ ft[/tex]

The new length must be [tex]2\frac{2}{15}\ ft[/tex]

The new picture must be [tex]2\frac{2}{15}[/tex] feet or 2.1334 feet in length.

We know, [tex]1\ inch= \frac{1}{12}\ feet[/tex]

Given to us:

Initial length, [tex]L_i =8 inches[/tex];

Initial height, [tex]H_i =15\ inches[/tex];

Final height, [tex]H_f = 4\ feet[/tex];

We know that a when a picture is blown up(enlarged), it is always done in a specific ratio, therefore

Ratio, [tex]r=\dfrac{Length}{Height}[/tex]

So,

[tex]\dfrac{Initial\ Length}{Initial\ Height} =\dfrac{Final\ Length}{Final\ Height}[/tex],

[tex]\dfrac{8}{15} =\dfrac{Final\ Length}{4}\\\\{Final\ Length}=\dfrac{8}{15} \times 4 \\\\{Final\ Length}=\dfrac{32}{15}\\\\{Final\ Length}=2\frac{2}{15}\ feet[/tex]

Hence, the new picture must be [tex]2\frac{2}{15}[/tex] feet or 2.1334 feet in length.

Answer:

the area is 2

Step-by-step explanation:

The area of the triangle will be 1 inch².

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.

Given that the height of the triangle is 1/8 inches and the base of the triangle is 16 inches. Therefore, the area of the triangle will be,

Area of the triangle = 0.5 × Height × Base

                                 = 0.5 × (1/8) inches × 16 inches

                                 = 1 inch²

Hence, the area of the triangle will be 1 inch².

The speed of a wave is the product of the wavelength and its frequency.

The speed of the wave is 20m/s

Given

[tex]\lambda = 10m[/tex] --- the wave length

[tex]f =2Hz[/tex] --- the frequency

[tex]A = 3m[/tex] --- the amplitude

The speed of wave (v) is calculated as follows:

[tex]v =f\lambda[/tex]

Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]

[tex]v = 2Hz \times 10m[/tex]

[tex]v = 20ms^{-1}[/tex]

Hence, the speed of the wave is 20m/s
