Estimate 349.6-112.8

Answer:

0.

Step-by-step explanation:

I can't really explain it, but think of it is 4/5 - 4/5 instead of -4/5 + 4/5.

Step-by-step explanation:

Suppose the persons are a, b, c, d, e, f and g.

Let us also assume that a and b always sit together.

Let us then put the remaining 5 persons in a circular arrangement. It can be done in (5–1)! = 4! = 24 ways. Now, the pair (a,b) can be placed between any two persons already placed in circular order. There are 5 such gaps. Finally the pair (a,b) can be placed in two ways viz. (a,b) and (b,a).

So, total number of ways a group of 7 persons can be seated around a circular table where 2 specified persons always sit together is 24 X 2 X 5 = 240

This is an exponential expression with 10 as the base and 4 as the exponent.

=============================================

Explanation:

We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.

The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.

Side note: 10^4 = 10,000 = ten thousand

Answer:

27.5%

Step-by-step explanation:

Hi!

To do this problem, we have to set up a percent proportion:

[tex]\frac{3.3\\}{x}[/tex] = [tex]\frac{12}{100}[/tex]

In this problem, the denominators are the percent values and the numerators are the numerical value.

x = [tex]\frac{3.3*100}{12}[/tex]

x = [tex]\frac{330}{12}[/tex]

x = 27.5%

Hope this helped.

Answer:

Since from the laws of exponents we have that x−n=1xn , it implies that we may write 18=8−1 . 18=123=2−3.

Answer:

Turbo jetpack = 6(d + 7)

Xray vision glasses = 2d - 5

Invisible shield = 10d + 1

18d + 38 ;

128 dozen accessories

Step-by-step explanation:

Let the number of boxes sold = d

Turbo jetpack = 6(d + 7)

Xray vision glasses = 2d - 5

Invisible shield = 10d + 1

Combined number of accessories sold :

6(d + 7) + (2d - 5) + (10d + 1)

6d + 42 + 2d - 5 + 10d + 1

18d + 38

If 5 dozens are sold

d = 5

Number of accessories sold :

18(5) + 38

90 + 38 = 128 dozens accessories

(5 x + 7)(x^2 + 3)

Answer:

Width of the rectangle is 8 feet

Length of the rectangle is  13 feet

Step-by-step explanation:

Complete question -

The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 feet, what is its length?

Solution

Let the width  of the  rectangle be X feet

Length of the rectangle would be 2X -3  feet

Perimeter of the rectangle is 2 (length + breadth)

Substituting the given values, we get -

Perimeter =  2 (length + breadth)

[tex]42 = 2 [(2X-3) + X]\\42 = 4X - 6 + 2X\\48 = 6X\\X = 8[/tex]

Width of the rectangle is 8 feet

Length of the rectangle is  [tex]2*8 -3 = 16-3 = 13[/tex] feet

Answer:

4187 ft³

Step-by-step explanation:

[tex]\frac{4}{3}[/tex]πr³

π = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

Radius = 20 / 2 = 10 feet

(4/3) x 3.14 x 10³ = 4187 ft³

Answer:

175 in³

Step-by-step explanation:

First the area of the triangle:

S: ½a×b×SinC

½×7in×10in×Sin90°===> 35in²

and now the volume

35 in²×5 in=175 in³

Answer:

1/2 and 9/14

Step-by-step explanation:

Let the first fraction be 1/2

Let the second fraction be x

1/2 + x= 8/7

x= 8/7-1/3

= 16-7/14

= 9/14

Hence the two numbers are 1/2 and 9/14

Answer:

x^2+9x+8

Step-by-step explanation:

Expand the following:

(x + 1) (x + 8)

(x + 1) (x + 8) = (x) (x) + (x) (8) + (1) (x) + (1) (8):

x x + 8 x + x + 8

x x = x^2:

x^2 + 8 x + x + 8

Grouping like terms, x^2 + 8 x + x + 8 = x^2 + (8 x + x) + 8:

x^2 + (8 x + x) + 8

8 x + x = 9 x:

Answer: |

| x^2 + 9 x + 8

Answer:

D. 4 • 1 = 4

Step-by-step explanation:

In Mathematics, we have two kinds of Identity property

a) Identity property of Addition

This means that when you add a number to zero, it gives you that same number

Example: 6 + 0 = 6

b) Identity property of Multiplication,

This means that, when a number is multiplied by 1, it gives that same number.

Example: 8 × 1 = 8

Therefore, from the above question, the equation that demonstrates identity property is 4 • 1 = 4

Answer:

Mass = density * volume

Mass = 6 g/cm^3 / 34 cm^3

Mass = 0.1764705882 grams

Step-by-step explanation:

Answer:

204 g

Step-by-step explanation:

*I thinks you have made a mistake with the unit of the volume*

Density = mass / volume

Mass = volume * density

mass = 6 * 34

mass =204 g
