if a number × is increased by 11,the result is 35.What is the number?​

Answer:

Box dimensions:

L = 3 ft

D = 6 ft

H = 1 ft

Volume  V = 18 ft³

Step-by-step explanation:

a) Each side of the future box is

L = 5 - 2*x     D = 8 - 2*x  

height of the box is   x

Then the volume of the box as function of x is:

V(x) =  ( 5 - 2*x ) * ( 8  - 2*x ) * x

V(x) = ( 40 - 10*x - 16*x + 4*x² ) * x

V(x) = 40*x - 26*x² + 4*x³

Tacking derivatives on both sides of the equation:

V´(x) = 40 - 52*x + 12x²     or     V´(x) = 20 - 26*x + 6*x²

If V´(x) = 0

6*x² - 26*x + 20  = 0

Solving for x

x₁,₂  = (-b ± √ b² - 4*a*c  ] /2*a

x₁,₂  = ( 26  ±  √ 676  - 480  ) / 12

x₁,₂  =  (26 ± 14 )/ 12

x₁  = 1

x₂ = 3,33        ( we dismiss this solution since is not feasible according to cardboard dimensions )

Then the sides of the box are:

L = 5 -2*x      L  =  5 - 2*1     L = 3 ft

D = 8 - 2*x    D  = 8 - 2*1     D = 6 ft

H = x = 1 ft

And the volume is    V = 6*3*1 = 18 ft³

Answer:

The nth term is [tex]a_n = 4 - 5(n-1)[/tex]

The 60th term of the sequence is -291.

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and it is called common difference.

The nth term is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

In which [tex]a_1[/tex] is the first term and d is the common difference.

4,-1,-6

The common difference is:

[tex]d = -1 - 4 = -5[/tex]

First term [tex]a_1 = 4[/tex]

So

[tex]a_n = a_1 + (n-1)d[/tex]

[tex]a_n = 4 - 5(n-1)[/tex]

60th term:

[tex]a_{60}[/tex]. Si

[tex]a_{60} = 4 - 5(60-1) = -291[/tex]

The 60th term of the sequence is -291.

Answer:

38.5ft²

Step-by-step explanation:

Triangle area formula = [tex]\frac{1}{2} * b * h[/tex]

Triangle area = [tex]\frac{1}{2} * 11 * 7[/tex]

Triangle area = 0.5 * 11 * 7

Triangle area = 38.5ft²

Step-by-step explanation:

Answer:

5/8 is in the simplest form already.

Step-by-step explanation:

It cant be lowered anymore, due to 5 not being divisible by 4, 2, or 8, which is what 8 is divisible by.

Answer:

Step-by-step explanation:

We're going to say Job A is the charge at Jim's shop. For h hours, that charge will be the sum of the parts cost and the hourly charge:

  j = 25 +55h

Job B is the charge at Myron's shop. Similarly, that charge is ...

  m = 50 +30h

__

The two charges are equal when ...

  j = m

  25 +55h = 50 +30h

  25h = 25 . . . . . . . . . . . subtract 25+30h from both sides of the equation

  h = 1 . . . . . . . . . . divide by 25

The charges are the same at the two shops for 1 hour worked.

Additional comment

You may be expected to write your equations using y for the charge and x for the hours. I like to use variable names that remind me what they stand for.

__

In general, when you have rates that have different fixed fees and different per-quantity costs, the "break even" quantity is the ratio of the difference in fees to the difference in per-quantity costs. Here the parts (fees) differ by $25, and the per-hour cost differs by $25, so the number of hours is 25/25 = 1 to make the charges equal.

Answer:

1. A

2.C

Step-by-step explanation:

1. 170+170+10+10=360

Answer:

A. Translation

Step-by-step explanation:

Given

Preimage

[tex]J = (-6,9)[/tex]

[tex]K = (-6,4)[/tex]

[tex]L = (-3,4)[/tex]

Image

[tex]J' = (2,9)[/tex]

[tex]K' = (2,4)[/tex]

[tex]L' = (5,4)[/tex]

Required

Which transformation occurred

The transformation that occurs is translation because each of the preimage were translated or shifter right by 8 units.

The rule applied here is:

[tex](x,y)=>(x+8,y)[/tex]

So, we have:

[tex]J = (-6,9)[/tex] [tex]==> (-6+8,9) = (2,9)[/tex]

[tex]K = (-6,4)[/tex] [tex]==> (-6+8,4) = (2,4)[/tex]

[tex]L = (-3,4)[/tex] [tex]==> (-3+8,4) = (5,4)[/tex]

Hence, the transformation is (a) Translation
