First, you need to multiply 6 by 7, then add 1

43/7

Answer:

[tex]\frac{43}{7}[/tex]

Step-by-step explanation:

6 x 7 + 1

there is 6 whole fractions so it would be [tex]\frac{7}{7}[/tex] 6 times then add the [tex]\frac{1}{7}[/tex]

which would be [tex]\frac{43}{7}[/tex]

hopefully that made sense!

Answer:

2376 square feet

Step-by-step explanation:

40 x 15 = 600

40 x 24 = 960

1/2 x (24 x 9) = 108

600 + 600 + 960 + 108 + 108 = 2376

Answer:

SA= 678.24 in^2

Step-by-step explanation:

SA = (pi)(r^2) + (pi)(r)(l)

r = radius

h = height

l = slant height

Pi = 3.14

Slant height:

l^2 = h^2 + r^2

l = sqrt (144+81)

= 15

SA = (pi)(9^2) + (pi) (9) (15)

SA = 254.34 + 423.9

SA= 678.24 square inches

If the slant height of the cone is 15 inches. Then the surface area of the cone will be 678.58 square inches.

Find the area that its outer surfaces possess. The Sum of all those surface areas is the surface area of the considered object.

If a right cone has a radius of 9 inches and a height of 12 inches.

Then the surface area of a right cone will be

The slant height is given as

l² = 9² + 12²

l² = 81 + 144

l² = 225

l = 15

Then the surface area will be

Surface area = πr² + πrl

Surface area = π x 9² + π x 9 x 15

Surface area = 81π + 135π

Surface area = 216π

Surface area = 678.58 square inches

Answer:

  √40 ≈ 6 4/13 ≈ 6.31

Step-by-step explanation:

The estimate by linear approximation starts with the recognition that ...

  40 = 36 +4 = 6² +4

and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.

The linear approximation to √40 is ...

  √40 ≈ 6 4/13 ≈ 6.31

__

There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.

  (82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places

_____

Additional comment

When you write the value in terms of a square and a remainder:

  n = s² +r

then the above linear approximation of √n can be written as ...

  √n ≈ s +r/(2s+1)

Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:

  √n ≈ s +r(2s+1)/(2s(2s+1) +r)

For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...

  n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.

Answer:

y=0x-5

Step-by-step explanation:

The required equations computed from the data given are :

Given the Parameters :

The Revenue Function, R(x) :

The Cost equation, C(x) :

The Profit function, P(x) ::

P(x) = R(x) - C(x)

P(x) = 860x - 5x² - (6000 + 120x)

P(x) = 860x - 5x² - 6000 - 120x

P(x) = 740x - 5x² - 6000

Number of apartments required to break even :

At break even ;

P(x) = 0

740x - 5x² - 6000 = 0

Divide through by 5

-x² + 148 - 1200 = 0

Using a quadratic calculator :

The roots are (139.39, 8.60)

Therefore. The company will break even at 139 apartments rented or 9 apartments.

Answer:

5 / 6

Step-by-step explanation:

2 [ ( 3x + 5 ) - 7 ] = 3 ( 4x - 3 )

2 [ ( 3x + 5 - 7 ] = 3 ( 4x - 3 )

2 [ 3x - 2 ] = 3 ( 4x - 3 )

6x - 4 = 12x - 9

12x - 9 = 6x - 4

12x - 6x = - 4 + 9

6x = 5

Answer:

Setting up problems like this requires a "system of equations." We'll call the two numbers "A" and "B." Make an equation out of the first sentence. "Sum" means the answer to an addition problem.

A + B = 45

After that, make an equation out of the second sentence. "Difference" means subtraction.

A - B = 3

There are two ways to solve this problem. The two ways are called "elimination" and "substitution." I don't know which way you usually do it, but for this case, elimination is more efficient, so I'll teach you how to do that. Look how "B" is positive in the first equation, but negative in the second equation. If these two equations get added together, the B-terms will cancel.

A + B = 45

A - B = 3

-------------

2A = 48

A = 24

Perfect, we got one of the numbers, which is 24. Plug in A = 24 into any of the equations to find B.

A + B = 45

24 + B = 45

B = 21

This means that our two magic numbers are 24 and 21. The product of these numbers can be found by multiplying them to get 504 (C). I hope this helps, and good luck with the rest of your math class!
