Answer:

IJ = 68.6 feet

Step-by-step explanation:

In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=84°, and HI = 69 feet. Find the length of IJ to the nearest tenth of a foot.

We solve the above question using the Trigonometric function of Sine

sin x = Opposite/Hypotenuse

x = ∠H=84°

Opposite = IJ

Hypotenuse = HI = 69 feet.

Hence

sin 84 = IJ/69

Cross Multiply

IJ = sin 84 × 69

IJ = 68.62201078 feet

Approximately = 68.6 feet

Step-by-step explanation:

Given:

A  store manager purchased hoodies for $24.99 apiece.

He sells the hoodies for $32.

To find:

The markup percentage.

Solution:

We have,

Cost price (C.P.) = $24.99

Selling price (S.P.) = $32

We know that,

[tex]\text{Markup percentage}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{32-24.99}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{7.01}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{701}{24.99}[/tex]

[tex]\text{Markup percentage}\approx 28.05[/tex]

Therefore, the markup percentage is 28.05%.

Answer:

A = 50.24 cm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 4

A = (3.14) 4^2

A =3.14 * 16

A = 50.24 cm^2

Answer:

2)an = 5n + 1

Step-by-step explanation:

This is an arithmetic series.

6 , 11 , 16, 21 ,.....

First term = [tex]a_{1}[/tex] = 6

Common difference = d = second term - first term

                                = 11 - 6 = 5

nth term = [tex]a_{1}+(n-1)*d[/tex]

             = 6 + (n - 1) * 5

            =  6 + n * 5 - 1*5

            = 6 +5n - 5

           = 6 - 5 + 5n

           = 1 + 5n

Answer:

Step-by-step explanation:

You need to give us the choices. However, I will try and give you the answer.

The highest common factor is 8

8(x^2 - 3)     This is the answer I think the question expects.

8(x - √3 )(x + √3)  this is also possible

Answer:

If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

Answer: 6 2/3

Step-by-step explanation:

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:

= 10/3

= 3 1/3

She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:

= 3 1/3 × 2

= 10/3 × 2

= 20/3

= 6 2/3

Answer:

-7n is the answer

Step-by-step explanation:

It's easy.

Answer:

1. Move the variables to one side: 3(-4+4) = -3n

2. Distribute. You will end up with 0 = -3n

3. Divide both sides by -3. n = 0

Step-by-step explanation:

Answer:

n=0

Step-by-step explanation:

3(-4+4)+5n=2n

first distribute

-12+12+5n=2n

combine like terms

5n=2n

subtract 2n on both sides

3n=0

divide by 3 on both sides

n=0/3

which is also equal to

n=0

Step-by-step explanation:

10X+ 180= 500

10X= 500-180

10X= 320. .....divine both sides by 10 to solve for X

X = 32.

check

10(32)+180 = 500

320+180 =500

500 =500...confirmed

Answer:

Step-by-step explanation:

Look at 3%2At%2B7=%28+-8+%29.

Moved these terms to the left  %28 +8+ %29

It becomes 3%2At%2B7%2B _green%28+8+%29=0.

Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.

Added fractions or integers together

It becomes 3%2At% 2B % 28+15+%29=0.

Look at highlight_red%28+3%2At%2B15+%29=0.

Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0

It becomes highlight_green%28+0+%29=0.

Result: 0=0

This is an equation! Solutions: t=-5.

Answer: t= -1/3

Step-by-step explanation:

3t+7=-8

subtract 7 from 7 and 8 (this cancels out the 7)

left with 3t = -1

divide 3 into 3t and -1

the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3

Answer:

(-8)-(-7)=  -1

Step-by-step explanation:

Answer:

x=10, x=-2

Step-by-step explanation:

x^2-5x-3x+15=35

x^2-8x-20=0

Multiply to -20, add to -8: -10, 2

(x-10)(x+2)=0

x=10, x=-2

Answer:

x = −2 or x = 10

Step-by-step explanation:

(x - 3)(x - 5) = 35

x^2 − 8x + 15 = 35

x^2 − 8x + 15 − 35 = 35 − 35

x^2 − 8x − 20 = 0

(x+2)(x−10) = 0

x + 2 = 0 or x − 10 = 0

x = −2 or x = 10

Answer:

  0.666... = 6/9 = 2/3

Step-by-step explanation:

The repeating decimal 0.666... can be turned to a fraction as follows.

Let x represent the value of the number. Then 10x is ...

  10x = 10(0.666...) = 6.666...

Subtracting x gives ...

  10x -x = 6.666... - 0.666... = 6.000...

  9x = 6

Dividing by 9 and simplifying, we have ...

  x = 6/9 = 2/3

__

It can be worthwhile to remember that  1/9 = 0.111... repeating.

Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating

and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating

Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...

  2 ÷ 3 = 0.6666667 or 0.66666666667

or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.

Additional comment

A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.

Answer:

Monthly salary= $4,228

Step-by-step explanation:

Giving the following information:

Fixed salary= $2,500

Sales commission= 10%

Sales= $24,600

To calculate the monthly salary, we need to use the following formula:

Monthly salary= fixed income + commission

Commission= (24,600 - 15,000)*0.18

Commission= $1,728

Monthly salary= 2,500 + 1,728

Monthly salary= $4,228
