A sequence is given by the equation a, = an 1-2. If a1 =12, what is the
value of the term of A4 ?

Answer:

he makes $112.50

Step-by-step explanation:

first you have to find out how much he makes before tax is taken out. all you do is multiply 12.50 by 30, which gives you $375.00. then, you can either put in the calculator 30%375 or 0.3×375(both are the same thing) and you should get $112.50

Answer:

y - 4 = -2(x - 5)

Step-by-step explanation:

point slope form is  y-y1 = m(x-x1)

the original equation is given in slope intercept form y = mx + b

Parallel lines have equal slopes so from the given equation  y = -2x-3

the slope m = -2.

Use the given point (5,4) as (x1, y1).

y - 4 = -2(x - 5)

Answer:

[tex]\displaystyle y - 4 = -2(x - 5)[/tex]

Step-by-step explanation:

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so −2 remains as is as you proceed with plugging the information into the Point-Slope Formula:

[tex]\displaystyle [5, 4] \\ \\ \boxed{y - 4 = -2(x - 5)}[/tex]

21=x

3x-10+2x+30=180(linear pair)

5x+20=180

5x=160

Answer:

60

Step-by-step explanation:

The number is represented as x.

81 is added to a number is

81 + x

39 less than three times the number

3x - 39

So

81 + x = 3x - 39

Solve for x.

81 + x = 3x - 39 Add 39 to each side so 39 cancels on the right.

81 + x + 39 = 3x - 39 + 39

81 + x + 39 = 3x

81 + 39 + x = 3x

120 + x = 3x Subtract x from each side.

120 + x - x = 3x - x

120 = 3x - x

120 = 2x    Divide each side by 2

120/2 = 2x/2

120/2 = x

60 = x

Answer:

Step-by-step explanation:

8/12 ÷ 1/12 = 8/12×24/1=192/12=16

The required number of books that can be fitted to the 8/12 yard long bookshelf is 16 books.

Given that,
A small bookshelf is 8/12 yards long. how many books can fit on the shelf if the width of each book is 1/24 yard is to be determined.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

here,
The total length of the shelf = 8 / 12 yard
Width of a book = 1 / 24 yard
So the total number of books that can be accumulated on the shelf will be the ratio of the total length of the shelf to the width of a book. So,
Total books = 8 / 12 / {1 / 24]
                    = 8 * 24 / 12
                    = 16

Thus, the required number of books that can be fitted to the 8/12 yard long bookshelf is 16 books.

#SPJ2

Answer:

denote the number of hits that sanchez had with since washington had 18 more hits than sanchez we can say that washington had + 18 hits.

since the total number of hits is 308 we can write

+ ( + 18) = 308.

This is an equation for finding .

2 + 18 = 308

2 = 290

= 145.

so sanchez had 145 hits.

to find the number of hits by washington add 18:

+ 18 = 145 + 18 = 163.

Answer: sanchez had 145 hits and washington had 163 hits.

Step-by-step explanation

There are many ways to prove this identity. But, I will use the simplest one. If you have a right triangle, the length of the horizontal side is x, the length of the vertical side is y, and the hypotenuse is r. So, the relation between x and r can be written in cosine form:

[tex]\cos\theta=\frac{x}{r}[/tex]

The relation between y and r can be written in sine form:

[tex]\sin\theta=\frac{y}{r}[/tex]

Pythagoras told you that for the right triangle [tex]x^{2}+y^{2}=r^{2}[/tex] should be satisfied. Substitute x and y from the cosine and sine form:

[tex](r\cos\theta)^{2}+(r\sin\theta)^{2}=r^{2}[/tex]

[tex]r^{2}\cos^{2}\theta+r^{2}\sin^{2}\theta =r^{2}[/tex]

the square of r will cancel out, and you can get your identity:

[tex]\cos^{2}\theta+\sin^{2}\theta=1[/tex]

Question:  What is 40, percent of 10?

Answer:  4

Answer:

x = 14

Step-by-step explanation:

1/2(x - 4) = 5                     - Given

1/2x - (1/2 * 4) = 5             - Distribute

1/2x - 2 = 5                       - Multiply 1/2 by 4

1/2x = 7                             - Add 2 to both sides of the equation

x = 14                                 - Divide both sides of the equal by 1/2

Answer:

Step-by-step explanation:

You should substitute x = -1 to the f(x) and you will find:

[tex]f(-1)=\left(\frac{1}{2}\right)^{-1}=\frac{1}{2^{-1}}=2[/tex]

So, the answer for the ? is 2.

Using the exponential distribution, it is found that there is a 0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The probability of finding a value higher than x is:

[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]

In this problem, the mean is of two minutes, hence the decay parameter is given by:

[tex]\mu = \frac{1}{2} = 0.5[/tex]

The probability that it takes more than 3 minutes for the next call to occur is given by:

[tex]P(X > 3) = e^{-0.5 \times 3} = 0.2231[/tex]

0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.
