Answer:

x=47

Step-by-step explanation:

Let's solve your equation step-by-step.

180=x+3x−8

Step 1: Simplify both sides of the equation.

180=x+3x−8

180=x+3x+−8

180=(x+3x)+(−8)(Combine Like Terms)

180=4x+−8

180=4x−8

Step 2: Flip the equation.

4x−8=180

Step 3: Add 8 to both sides.

4x−8+8=180+8

4x=188

Step 4: Divide both sides by 4.

4x4=1884

x=47

Answer:

Square B 9 × 7.5

Step-by-step explanation:

The computation is shown below:

9 × 7 = 63 > 55

8 × 5 = 40 < 55

5 × 10 = 50 < 55

As it can be seen that in only one condition the total of square feet is less and in the other conditions the total of square feet is more

Therefore the option Square B is correct

And, the rest of the options are incorrect

Step-by-step explanation:

the breadth of the rectangle is 3

A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).

Area =9x -6 ,

length=3x-2,

 breath =?​

Therefore, the area of a rectangle formula states that:

Area of rectangle = Length x Width

A = L * W, where A is the area, L is the length, W is the width or breadth.

now put the given value in the formula

9x-6 = (3x-2 )*W

3( 3x -2) / (3x-2) = W

W =3

Hence , the breadth of the rectangle is 3

Answer:

10,000

Step-by-step explanation:

f = feet above ground

r = rate of descent

m = minutes

f = 30000 - r · m

f = 30000 - 20000m

After five minutes:

f = 30000 - 2000(5)

f = 30000 - 10000

f = 20000

After five minutes the plane is at 10,000. feet.

Answer:

Total boxes= 75

Step-by-step explanation:

Giving the following information:

A baseball bat factory produces 24,000 bats per day and uses 50 boxes for packing the bats.

First, we need to determine the number of bats that fits into a box:

Bats per box= 24,000 / 50

Barts per box= 480

Now, the number of boxes for 36,000 bats:

Total boxes= total bats / bats per box

Total boxes= 36,000/480

Total boxes= 75

Answer:75

Step-by-step explanation:

Bats 24000/50

Box 480

Answer: A. [tex]2\times10^{-6}[/tex].

Step-by-step explanation:

Given: The diameter of bacterium = 0.0000029 meter

≈  0.000002 meter  [ with 6 decimal places]

[tex]=\dfrac{2}{1000000}=\dfrac{2}{10^6}[/tex]

[tex]=2\times10^{-6}[/tex] meters    [[tex]\dfrac{1}{a^n}=a^{-n}[/tex]]

i.e. [tex]2\times10^{-6}[/tex] closest to 0.0000029.

Hence, the correct option is A. [tex]2\times10^{-6}[/tex].

Use property : [tex]x^{-a}=\dfrac{1}{x^a}[/tex]

[tex]3x^7{\cdot} (\dfrac{4}{x^5})^2\\ =3x^7{\cdot} \dfrac{16}{x^{10}}\ \ [\because (x^a)^b=x^{a\times b}]\\\\=\dfrac{48}{x^3}[/tex]

So, the simplified form of the given expression is [tex]\dfrac{48}{x^3}[/tex]

I need measurements please to add an answer

By using trigonometric functions and law of sines, the length h indicated in the figure is approximately 87.997 feet.

In this system we find a picture of a geometric system formed by the two triangles, one of which with a right angle. We need to use trigonometric functions, law of sines and law of cosine to determine the missing length. First, use the law of sines:

(129 ft) / sin 33.7° = r / sin 26°

r = 129 ft × sin 26° / sin 33.7°

r ≈ 101.920 ft

Lastly, we find the value of the length h by trigonometric functions:

h = r · sin 59.7°

h = (101.920 ft) · sin 59.7°

h ≈ 87.997 ft

The length h indicated in the figure is approximately 87.997 feet.

Answer:

Volume = 251.2 cubic inches

Step-by-step explanation:

You get the volume of a cylinder by multiplying the area of the base with the height.

Since the diameter is 4 inches, the radius of the base is 4/2 = 2 inches

So, volume = base area* height

                  = 2² * 3.14 * 20

                  = 251.2

The approximate volume of the cylinder mailling tube, to the nearest tenth of a cubic inch is 251.2 in³.

Volume of cylinder is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

Volume of cylinder is the can be given as,

[tex]V=\pi r^2h[/tex]

Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.

A cylindrical mailing tube has a length of 20 inches and diameter of 4 inches. The radius is half of the diameter of the cyilnder. Thus the radius of the cylinder is,

[tex]r=\dfrac{4}{2}\\r=2\rm\; in[/tex]

Put the value of radius and height of the cylinder in the above formula as,

[tex]V=3.14 (2)^2(20)\\V=251.2\rm\; in^3[/tex]

Thus, the approximate volume of the cylinder mailling tube, to the nearest tenth of a cubic inch is 251.2 in³.

Answer:

Step-by-step explanation:

no. of people = x

total parking costs = 10.25x

total tickets cost = 35.25x

total = 10.25x + 35.25x

suppose 3 people go, then the total cost will be

10.25(3) + 35.25(3) = 136.5 and this is greater than 116

Suppose 2 people go then the cost will be

10.25(2) + 35.25(2) = 91 which is less than 116

so only 2 people can go.
