Answer: 48 arrangements

Step-by-step explanation:

Total persons = 5

Total seats = 5

Total arrangements

= 2 * 4!

= 2 * (4 * 3 * 2)

= 2 * 24

= 48

Answer:

a)[tex]-\frac{1}{12}[/tex]

d)[tex]-\frac{1}{8}[/tex]

Step-by-step explanation:

a) Find a common denominator. 12 (3 × 4 = 12)

Convert the fractions to have a denominator of 12.

[tex]\frac{2}{3}[/tex] → [tex]\frac{8}{12}[/tex]

[tex]\frac{3}{4}[/tex] → [tex]\frac{9}{12}[/tex]

[tex]\frac{8}{12}[/tex]- [tex]\frac{9}{12}[/tex] = [tex]-\frac{1}{12}[/tex]

d) Find a common denominator. 8 (4 × 2 = 8; 8 × 1 = 8)

Convert the fractions to have a denominator of 8.

[tex]\frac{3}{4}[/tex] → [tex]\frac{6}{8}[/tex]

[tex]\frac{5}{8}[/tex] → [tex]\frac{5}{8}[/tex]

- [tex]\frac{6}{8}[/tex] - (-[tex]\frac{5}{8}[/tex])=?

Remember, 2 subtractions signs cancel each other out.

- [tex]\frac{6}{8}[/tex] + [tex]\frac{5}{8}[/tex] = [tex]-\frac{1}{8}[/tex]

Answer:

Ok, here goes:  f(3) means take f(x) and plug in 3 wherever we see x.  So

f(3) = 12*39 + 3 = 236196 + 3

f(3) = 236199

Likewise, f(-3) means take f(x) and plug in (-3) wherever we see x.  So

f(-3) = 12*(-3)9 + (-3) = -236196 - 3

f(-3) = -236199

Putting those two things together, we get

f(3) + f(-3) = 236199 - 236199 = 0

Answer:

Step-by-step explanation:

Step-by-step explanation:

x = the total money she had first.

x - x×1/4 - (x - x×1/4)×1/2 = 15

you see, first we needed to deduct 1/4 of x from x. that left us with (x - x×1/4). and from that we need to deduct 1/2.

now, we can simplify :

(x - x×1/4) = (x×4/4 - x×1/4) = x×3/4

x×3/4 - x×3/4 × 1/2 = 15

x×3/4 - x×3/8 = 15

we multiply both sides by 8 (4 is a factor of 8, so this handled both fractions perfectly) :

x×3×2 - x×3 = 120

6x - 3x = 120

3x = 120

x = $40

she had $40 at the beginning.

Answer:

3k + 20

Step-by-step explanation:

5(k + 4) - 2k

First distribute

5k + 20 - 2k

Then subtract (combine) the like terms

3k + 20

Answer:

The answer is 3k + 20

Step-by-step explanation:

5k + 20 - 2k

Combine like terms: 5k - 2k = 3k

which makes your answer 3k + 20

Answer:

the range is {7,5,1}

Step-by-step explanation:

To find the range, just plug in the domain into the function.

f(-1) = -2(-1) + 5 = 7

f (0) = -2(0) + 5 = 5

f(2) = -2(2) + 5 = 1

Answer:

Step-by-step explanation:

Let the total number of action figures = x

75% of x = 48

[tex]\dfrac{75}{100}*x=48\\\\Multiply \ by \ 100\\\\75*x =48*100\\\\Divide \ by \ 75\\\\x=\dfrac{48*100}{75}\\\\\\x=16*4\\\\x= 64[/tex]

Remaining action figures need to be collected = total figures - number of action figures I have

= 64 - 48 = 16

Number of weeks = 16 ÷ 2 = 8

It will take 8 weeks to collect 16 action figures.

Answer:

compound and elements

Step-by-step explanation:

a single atom is known as an element

a compound is two elements bonded together.

the given figure shows single atoms as well as two atoms bonded together therefore the figure is showing elements as well as compounds

Answer:

h(2) =0

h(-2) =4

h(0) = 2

h(2) = 0

Step-by-step explanation:

h(2) = 2^2-3(2)+2 =4 - 6 + 2 = 0

h(-2) = 2^-2 -3(-2) +2 = -4+ 6+2=4

h(0) =0^2 - 3(0)+2 = 0-0 +2 = 2

h(2) = 2^2-3(2)+2 =4 - 6 + 2 = 0

Answer:

0

Step-by-step explanation:

basically plug a and b back into the equation so (0)÷(48) will equal 0 which is equal to C because 0 out of any number is always equal 0 because you're not taking taking any value out of it

Answer:

Step-by-step explanation:

zero is always a nasty piece of work. You need to be careful how you handle it.  What do you get when you divide 0 by 48?

Answer, you don't get anything because no matter if b is 1 or 48, you get 0 as the result.

Answer: B

Answer:

Step-by-step explanation:

First, let's find the surface area of both the triangles

5x3=15

So, the surface area of the triangles is 15 sq.cm

Now, let's find the surface area of the base (large rectangle in the middle)

12x8=?

10x8=80

2x8=16

80+16=96

12x8=96

So, the surface area of the base, is 96sq.cm

Now, let's find the surface area of both of the side rectangles

12x5=60

60x2=120

So, the surface area of the two side rectangles is 120sq.cm

Now, let's find the total surface area by adding all of our answers.

120+96=216

216+15=231
