People enjoyed attending the concert in the park.
Twice as many men as women attended the concert.
If the total attendance was 714, how
many women
attended the concert?

Answers

Answer:

w = 238

Step-by-step explanation:

So create a system of equations if the number of m = 2w where the men's number is twice the women's number.  and m + w = 714 so substitute 2w for m

2w + w = 714 so 3w = 714, divide both sides by 3, you get w = 238

[tex]\sqrt{x+7} -1=x\\[/tex]

Answers

Answer:

x = 2 and x = -3

Step-by-step explanation:

We need to find the value of x in the below expression.

[tex]\sqrt{x+7} -1=x[/tex]

Adding 1 to both sides,

[tex]\sqrt{x+7} -1+1=x+1\\\\\sqrt{x+7}=x+1[/tex]

Squaring both sides,

[tex]x+7=(x+1)^2\\\\x+7=x^2+1+2x\\\\x^2+1+2x-x-7=0\\\\x^2+x-6=0\\\\x=2\ and\ -3[/tex]

Hence, this is the required solution.

[tex]\bf\huge x=2 [/tex]

Step-by-step explanation:

Given that :

[tex]\sqrt{x+7} -1=x\\[/tex]

to find :

[tex]\sqrt{x+7} -1=x\\[/tex]

explanation :

⟼ [tex]\sqrt{x+7} -1=x\\[/tex]

⟼ √x + 7 = x + 1

⟼ x + 7 = x² + 2x + 1

⟼ x + 7 - x² - 2x - 1 = 0

⟼ -x + 6 -x² = 0

⟼ x² + x - 6 = 0

⟼ (x-2) (x+3) = 0

⟼ x = 2 and x = -3

When x = -3 the original equation √x+7-1 = x does not hold true. We will drop x = -3 from the solution set.

Therefore,

⟼ x = 2.

verification :

⟼ let take x = 2

⟼ [tex]\sqrt{x+7} -1=x\\[/tex]

⟼ √2+7 - 1 = 2

⟼ √9 - 1 = 2

⟼ 3 - 1 = 2

⟼ 2 = 2

hence verified ☑️

Answers

Answer:

  (x +3)² +(y -2)² = 185

  (x -10)² +(y +2)² = 185

Step-by-step explanation:

One possible equation comes from using one of the points as center. The other possible equation comes from using the other point as center.

The radius can be found from the distance formula:

  r² = (x2-x1)² +(y2-y1)² = (10-(-3))² +(2-(-2))² = 169 +16 = 185

The circle formula is ...

  (x -h)² +(y -k)² = r² . . . . . . for center (h, k) and radius r

solution of equation x^2-2x=-2

Answers

Answer:

[tex]x=1\pm i[/tex]

Step-by-step explanation:

The given equation is :

[tex]x^2-2x=-2\\\\x^2-2x+2=0[/tex]

The above equation is a quadratic equation whose solution can be given by :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Here,

a = 1, b = -2 and c = 2

So,

 [tex]x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(1)(2)} }{2(1)}[/tex]

So,

[tex]x=1+i,1-i\\\\x=1\pm i[/tex]

So, the solution of the equation is [tex]1\pm i[/tex].

Answers

Answer:

Inequality is 15 = 7.5 + 1.5x

x = 5, he can buy 5 sour straws

Step-by-step explanation:

For the inequality, just set the total money he has (15) equal to the total cost of the nachos (7.5) and sour straws (1.5)

Since we don't know how many straws he can buy, use a variable, I used x.

You get 15 = 7.5 + 1.5x, which solved out gives you x = 5.

Suppose Huang invests $720 into an annuity every month for five years. At the end of five years, the account has a balance
of $50,000. How much of this balance is interest?
Round your answer to the nearest dollar.
Do NOT round until you have calculated the final answer.

Answers

Answer:

$6,800

Step-by-step explanation:

The interest earn after 5 years will be $6800.

It is given that Huang invests $720 into an annuity every month for five years and at end of 5 years balance was $50000.

We have to find out the interest earn.

What do you mean by interest ?

Interest is an additional amount of money that is paid by the bank to customer on the amount deposited in his account.

As per the question ;

Investment made by Huang = $720 for five years

At end of five years , account balance = $50000.

So ;

Five years = 60 months

and the investment is an annuity every month for five years.

If Huang invests $720 every month for 5 years then total investment is ;

= $720 × 60

= $43200

And account balance at end of 5 years = $ 50000

So ;

Interest earn will be ;

= $50000 - $43200

= $6800

Thus , the interest earn after 5 years will be $6800.

Mohamad, owner of an residential furnished apartment's in Dubai, performed an economic analysis 4 years ago when he decided to place an new eefficient central AC unit for each apartments instead of old split units windows type in each room. The estimates used and the annual worth analysis at MARR = 12% are summarized below. Two different AC brands were compared. LG York Cost and installation, $ -26,000 -36,000 Annual maintenance cost, $ per year -800 -300 Salvage value, $ 2,000 3,000 Electrical power savings, $ per year 25,000 35,000 Useful life, years 7 10 The spreadsheet in below sheet is the one Mohamad used to make the decision. York was the clear choice due to its substantially larger AW value, hence York AC units were installed. MARR 12% LG York Investment Annual Repair Investment Annual Repair Years and salvage maintenance savings and salvage maintenance savings 0 $26,000 $0 $0 $36,000 $0 $0 1 $0 $800 $25,000 $o $300 $35,000 250 $800 $25,000 $0 $300 $35,000 3 $0 $800 $25,000 $0 $300 $35,000 4 $0 $800 $25,000 $0 $300 $35,000 5800 $25,000 $0 $300 $35,000 6 $0 $800 $25,000 $0 $300 $35,000 7$2,000 $800 $25,000 $0 $300 $35,000 8 $0 $300 $35,000 9 $0 $300 $35,000 10 $3,000 $300 $35,000 AW $6,068 $800 elementi $25,000 $7,025 $300 $35,000 Total AW $18,701.17 $28,499.52 5 $0 During a quick review (year 4 of operation), it was obvious that the maintenance costs and repair savings have not followed (and will not follow) the estimates made 4 years ago. In fact, the maintenance contract cost is going from $300 this year (year 4) to $1200 per year next year and will then increase 7% per year for the next 6 years. Also, the electrical power savings for the last 4 years were $31,312 ( year 1). $27,565 ( year 2), $30,493( year3), and $32,903( year4), as best as Mohamad can determine. He believes savings will decrease by $3,349 per year hereafter. Finally, these 4-year-old AC units are worth nothing on the market now, so the salvage is zero, not $3000. Q1 - With these new estimates, What is the AW of the Investment and Salvage value for YORK AC unit? Q2 - With these new estimates, What is the FW of the Investment and Salvage value for YORK AC unit? Q3 - With these new estimates, what is the recalculated AW maintenance cost for the YORK AC units? Q4 - With these new estimates, what is the recalculated PW maintenance cost for the YORK AC units? Q5 - With these new estimates, what is the recalculated Total AW cost for YORK AC units. Q6. With these new estimates, what is the recalculated Total FW cost for YORK AC units. Q7 - With these new estimates, what is the recalculated Total PW cost for YORK AC units. Q8 - If these estimates had been made 4 years ago, would YORK still have been the economic choice, why explain your answer Q9 - What is difference in capital recovery amount for the YORK units with these new estimates? Q10 - If MARR is changed to 8% for the upcoming 6 years what will be the Total PW for the YORK units? 0 -26000 1 2 3 -36000 0 0 0 0 0 -800 -800 -800 -800 -800 -800 -800 4 5 25000 25000 25000 25000 25000 25000 25000 -300 -300 -300 -300 -300 -300 -300 -300 -300 -300 35000 35000 35000 35000 35000 35000 35000 35000 35000 35000 6 0 2000 7 8 0 0 0 3000 9 10 a grating that has 3200 slits per cm produces a third-order fringe at a 24.0 angle.
