Answer:

[tex]8n^7[/tex]

Step-by-step explanation:

Here is something to remember:

[tex]a^b[/tex] × [tex]a^c=a^{b+c}[/tex]

Start with:

[tex]8n^3[/tex] × [tex]n^4[/tex]

Multiply your bases.

[tex]8n[/tex] × [tex]n=8n[/tex]

Add your powers.

[tex]3+4=7[/tex]

Put them together.

[tex]8n^3[/tex] × [tex]n^4=8n^{3+4}[/tex]

Rewrite your answer.

[tex]8n^7[/tex]

Answer:

  23.  42 m^2

  24.  144 ft^2

  25.  68 cm^2

Step-by-step explanation:

The teacher should not need to spend any time teaching this. The area of the total figure is the sum of the areas of its parts. You already know that. And, you already know how to compute the areas of triangles and rectangles.

__

You may recall that the area of a triangle is ...

  A = 1/2bh

and the area of a rectangle with the same base and height is ...

  A = bh

So, a triangle with base b and height h has the same area as a rectangle with the same base (b) and half the height (h/2). Recognizing this makes these problems really simple.

__

23. The base of the rectangle and triangle is 7 m. The height of the triangle is 4 m, so its area is equivalent to adding 4/2 = 2 m to the 4 m height of the rectangle. Then the total area is ...

  A = (7 m)(4 m +(1/2)(4 m)) = (7 m)(6 m) = 42 m^2

__

24. Since there are two identical triangles of height 5, their total area is equal to that of a rectangle of height 5.

  A = (12 ft)(7 ft +5 ft) = 144 ft^2

__

25. The 5 cm height of the triangle makes it have an area equivalent to a rectangle 5/2 cm high.

  A = (8 cm)(6 cm +5/2 cm) = 68 cm^2

Note: we have read the fuzzy numbers as 8 cm wide, 6 cm high for the rectangle, and 5 cm high for the triangle. If your figure is different, please use the appropriate numbers in the calculation.

Answer:

The value is 9.7

Step-by-step explanation:

Use the Pythagorean theorem. [tex]a^{2} + b^{2}= c^{2}[/tex]

a=7 b=x c=12

[tex]7^{2} + x^{2}= 12^{2}[/tex]

[tex]49+x^{2} =144[/tex]

[tex]144-49=95[/tex]

[tex]x^{2} =95[/tex]

[tex]\sqrt{ x^{2}} =\sqrt{95}[/tex]

x=9.74679434481

x=9.7

Answer:

you end up with 75 divided by 3.

Step-by-step explanation:

75 divided by 3 - 8 + 8

add 60 and 15

3 - 2(4) + 2^3

multiply -2 by 4

3 - 8 + 2^3

multiply 2 by itself 3 times

3 - 8 + 8 (which gives you 3 again)

and you get 75 divided by 3

Answer:

multiply both sides by [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] x - 8 = 12

first step

Add 8 to both sides

[tex]\frac{2}{3}[/tex] x = 20

second step

Multiply both sides by [tex]\frac{3}{2}[/tex] to clear the fraction

x = [tex]\frac{3}{2}[/tex] × 20 = 30

Answer:

D(may not be D for everyone)

Step-by-step explanation:

The given statement is 2x + 5 = 11 :)

Answer:

Per pretty much means 1. So for example if I say I'm going 12 miles PER hour it means 12 miles every 1 hour.

Answer:

120 people

Step-by-step explanation:

The number of people as well as the number of chairs is 5

so that means there are exactly 120 ways in which they can be seated.

Answer:

3 units down

Step-by-step explanation:

Compared to

f(x) = |x|,

f(x) = |x| - 3 moves 3 units down.

h = 15√3/4

= 6.4875

≈ 6.5 cm

h = 3x

c₁ = 5 cm

c₂ = x

h² = c₁² + c₂²

(3x)² = 5² + x²

9x² = 25 + x²

8x² = 25

x² = 25/8

x = √25/8

x = 5/2√2

x = 5√2/4

h = 3x

= 3×5√2/4

= 15√2/4 cm

so each got 8.33

but practically we cannot give it 8.33 to each so we can give 8 to each

Answer:

5/7

Step-by-step explanation:

6/7-1/7=5/7

The answer is 6/7 - 1/7 = 5/7

Step by step explanation is in the image below. :)

Since PQ = QR = RS,

Let's set PQ equal to RS

2x + 3 = x + 10

Subtract x and 3 from both sides.

x = 7

PQ = 2x + 3 = 2(7) + 3 = 14 + 3 = 17

Since PQ = QR = RS,

QR = 17

Slope formula: y2-y1/x2-x1

We can use the points given to solve.

-2-4/3-(-2)

-6/5

Step-by-step explanation:

Answer:

[tex]-\frac{8}{45}[/tex]

Step-by-step explanation:

So when multiplying fractions, you would multiply the numerator of the first fraction by the numerator of the second fraction and make that product the numerator of the resulting fraction and multiply the denominator of the first fraction by the denominator of the second fraction and make that product the denominator of the resulting fraction. In other words:

[tex]\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}[/tex]

So lets multiply the two fraction together:

[tex]\frac{4}{5}*(-\frac{2}{9})==-(\frac{4*2}{5*9})=-\frac{8}{45}[/tex]

So now we found the product. Now we have to try to try to simplify the fraction. To do this, we must find the GCF of the numerator, 8, and the denominator, 45.

Factors of 8: 1, 2, 4, 8

Factors of 45, 1, 3, 5, 9, 15, 45

As we can see, the GCF of 8 and 45 are 1. The fraction is simplified as much as possible.

I hope you find my answer and explanation to be helpful. Happy studying. :)
