If x is 6, then 7x = ?

Answer:

$20

Step-by-step explanation:

0.50×8=4

4×5=20

50 cents per 1/8 of a pitcher so that would mean that 2/8 or 1/4 would be a dollar and if you keep going like that you will get to 4, then you multiply 4 and 5 to get 20.

Answer: 5

Step-by-step explanation:

The coordinate of the midpoint M = 5

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment ST, where the length of line segment ST  refers to the distance between its endpoints, S and T.

Given that M is the midpoint of ST

S______________M______________T

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

The endpoints of ST are -15 and 25.

So the midpoint between S and T is given by,

⇒ M = (25 - 15)/2,

⇒ M = 10/2

⇒ M = 5

Hence, the coordinate of the midpoint M = 5

Answer:

x²+8x+16

Step-by-step explanation:

f(x) = (x+4)²

= (x+4)(x+4)

= x² + 4x + 4x + 16

= x² + 8x + 16

23

Step-by-step explanation:

2 - [ -1]³ + [ 1 6 ] - [ - 1 - [ - 3 ]

= 2-[-1] + [16] -[-1]-[-3]

= 2+1+16+1+3

= 3+16+4

=3+20

= 23

   Sum of an arithmetic sequence is defined by the formula,

[tex]T_n=\frac{n}{2}[2a+(n-1)d][/tex]

Total length of the wooden boards will be [tex]14\frac{1}{6}[/tex] feet.

    It's given in the question,

Since, 1 inch = [tex]\frac{1}{12}[/tex] feet

Therefore, [tex]4[/tex] inch = [tex]\frac{4}{12}[/tex] feet

                             = [tex]\frac{1}{3}[/tex] feet

So, each stair is [tex]\frac{1}{3}[/tex] feet shorter than one below.

Now the sequence formed will be,

[tex]\frac{7}{2},[\frac{7}{2}-\frac{1}{3}],[\frac{7}{2}-\frac{2}{3}],......\frac{13}{6}[/tex]

[tex]\frac{21}{6},\frac{19}{6},\frac{17}{6}....\frac{13}{6}[/tex]

It's an Arithmetic sequence with common difference 'd' = [tex]-\frac{1}{3}[/tex] and first term 'a' = [tex]\frac{7}{2}[/tex] and nth term [tex]T_n=\frac{13}{6}[/tex]

If there are 'n' stairs, expression for the for the top stair of the arithmetic sequence will be,

[tex]T_n=a+(n-1)d[/tex]

[tex]\frac{13}{6}=\frac{21}{6}+(n-1)(-\frac{1}{3})[/tex]

[tex]\frac{13}{6}-\frac{21}{6}=-(n-1)\frac{1}{3}[/tex]

[tex]\frac{8}{6}=(n-1)\frac{1}{3}[/tex]

[tex]\frac{4}{3}=(n-1)\frac{1}{3}[/tex]

[tex](n-1)=4[/tex]

[tex]n=5[/tex]

Therefore, there are 5 stairs.

Now total length of the wooden boards = Sum of 5 terms of the sequence

                                                                    = [tex]\frac{n}{2}[2a+(n-1)(d)][/tex]

                                                                    = [tex]\frac{5}{2}[2(\frac{21}{6})+(5-1)(-\frac{1}{3})][/tex]

                                                                    = [tex]\frac{5}{2}[\frac{21}{3}-\frac{4}{3}][/tex]

                                                                    = [tex]\frac{17}{3}\times \frac{5}{2}[/tex]

                                                                    = [tex]\frac{85}{6}[/tex]

                                                                    = [tex]14\frac{1}{6}[/tex] ft

    Therefore, total length of the wooden boards will be [tex]14\frac{1}{6}[/tex] ft.

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

Explanation:

Let's say there are 1000 boards to be painted.

Working alone, Dan can paint 1000 boards in 10 hours, so his unit rate is 1000/10 = 100 boards per hour.

In 4.12 hours, he gets 4.12*100 = 412 boards painted. There are 1000-412 = 588 boards left which Natalie takes care of. This is when the two are working together.

Her unit rate is (588 boards)/(4.12 hours) = 142.718447 boards per hour. That value is approximate.

We multiply her unit rate by some unknown amount of time x, and this product will be the 1000 boards we started with. This way she would get the job down by herself.

So the equation we need to solve is

142.718447x = 1000

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

We divide both sides by 142.718447 to fully isolate x.

142.718447x = 1000

x = 1000/(142.718447)

x = 7.006803

That value is approximate.

If we round to the nearest whole number, then x = 7

So it takes about 7 hours for Natalie to get the job done if she works alone.

d=14

Step-by-step explanation:

1d/6+2/3=1(d-2)/4

Find the L.C.M.

d+4/6=d-2/4

Cross multiply

4d+16=6d-12

Collect like terms

16+12=6d-4d

28=2d

Divide through by the coefficient of d

2d/2=28/2

d=14

Answer:

d = 20

Step-by-step explanation:

1/6*d + 2/3 = 1/4*(d - 2) do the multiplying

d/6 + 2/3 = (d-2)/4 now add fraction

d/6 + 2/3 to add these up we need to multiply 2/3 with 1/2 and it will be 4/6

d/6 + 4/6 = (d+4)/6

(d+4)/6 = (d-2)/4 cross multiply

4d + 16 = 6d - 24 add like terms

16 + 24 = 6d - 4d

40 = 2d divide both sides by 2

20 = d

Answer:

Step-by-step explanation:

The revenue function is given to you, it's just not given in equation form. In equation form, the function is

R(p) = p(120 - 4p)

If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.

0 = p(120 - 4p). That means, by the Zero Product Property, that

p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that

p = 0 or

120 = 4p and

p = 30. The reasoning is the bold statement up above.

The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be

600 = p(120 - 4p)

Answer:

-220

Step-by-step explanation:

2,300-1 then we go into the negatives 0- -2,300
