Answer:

58.50

Step-by-step explanation:

Multiply 50 and .17 which equals 8.5 then add that to 50.

The amount of money in the account in December with a rate of 17% of the initial amount of $50 is $58.5.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A teenager puts $50 into an investment account in January.

Let, he deposited on first January.

If by December the balance in the account increases by 17%,

Let the amount by the 31 first of December will be

Then the amount will be given as

[tex]A = P (1 + \dfrac{r}{100})^t[/tex]

P = $50

r = 17%

t = 1

Then we have

[tex]\rm A = 50(1 + \dfrac{17}{100})^1\\\\A = 50(1 + 0.17)\\\\A = 50 * 1.17 \\\\A = 58.5[/tex]

Answer:

1.[tex]\:\left(-\infty \:,\:1\right)[/tex]
2.[tex]\:[11,\:\infty \:)[/tex]

Step-by-step explanation:

Given the following questions:

[tex]x-5 < -4[/tex]
[tex]-7x+6\leq-71[/tex]

To find the answer we solve as if it is a two-step equation where we add/subtract on both sides.

Question one:
[tex]x-5 < -4[/tex]
[tex]-5+5=0[/tex]
[tex]-4+5=1[/tex]
[tex]x < 1[/tex]
[tex]\:\left(-\infty \:,\:1\right)[/tex]

Question two:
[tex]-7x+6\leq-71[/tex]
[tex]6-6=0[/tex]
[tex]-71+-6=-77[/tex]
[tex]-7x\leq-77[/tex]
[tex]-7x\div-7=x[/tex]
[tex]-77\div-7=11[/tex]
[tex]x\leq11[/tex]
[tex]\:[11,\:\infty \:)[/tex]

Which means your answers are "(-∞, 1) and [11, ∞)."

Answer: x = 52.1 degrees

Step-by-step explanation:

The tangent of an angle is the opposite side divided by the adjacent side.

Therefore, tan(x) = 45/35.

We can find thte value of x by doing the arc tangent of 45/35, which makes x about 52.1 degrees.

Answer:

40/9

Step-by-step explanation:

Use the work formula, [tex]\frac{1}{A}[/tex] + [tex]\frac{1}{B}[/tex] = [tex]\frac{1}{T}[/tex], where A is the amount of time it takes one person, B is the amount of time it takes another person, and T is the time it takes for them to work together.

Plug in the times for David and Alex alone:

[tex]\frac{1}{10}[/tex] + [tex]\frac{1}{8}[/tex] = [tex]\frac{1}{T}[/tex]

Find the least common denominator, which is 40.

[tex]\frac{4}{40}[/tex] + [tex]\frac{5}{40}[/tex] = [tex]\frac{1}{T}[/tex]

[tex]\frac{9}{40}[/tex] = [tex]\frac{1}{T}[/tex]

Cross multiply and solve for T:

9T = 40

T = 40/9

So, if they worked together, it would take them 40/9 hours

Answer:

x=11

x=−5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  6*x+55-(x^2)=0

 -x2+6x+55  =0

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     -1

                     B   =    6

                     C   =   55

Accordingly,  B2  -  4AC   =

                    36 - (-220) =

                    256

Applying the quadratic formula :

              -6 ± √ 256

  x  =    ——————

                     -2

Can  √ 256 be simplified ?

Yes!   The prime factorization of  256   is

  2•2•2•2•2•2•2•2  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 256   =  √ 2•2•2•2•2•2•2•2   =2•2•2•2•√ 1   =

               ±  16 • √ 1   =

               ±  16

So now we are looking at:

          x  =  ( -6 ± 16) / -2

Two real solutions:

x =(-6+√256)/-2=3-8= -5.000

or:

x =(-6-√256)/-2=3+8= 11.000

To solve this you set up the equation:  x(8) +12 =y. In this equation x=, the number of paintbrushes and y=, the total cost of the purchase. If you plug in the number of paintbrushes that are being bought you should be able to get your Y(total cost).
