A lamp manufacturer uses 714 meters of electrical cord each week. The cord comes on spools that hold 12 meters each. How many spools of electrical cord does the manufacturer use each week?

Answers

Answer 1

divide 714 by 12

714 / 12 = 59.5 spools per week

Answer 2
714/12
= 59.5
The lamp manufacturer uses 59 and a half spools of electrical cord. If you round to the nearest whole number, he uses about 60 spools of cord.

*PLEASE HELP, BRAINLIEST* A salesman must commute 1 hour and 48 minutes from his house to the airport, fly to another city and take a bus to his destination. What is the total travel time one way?

Answers

Final answer:

The total travel time one way is 288 minutes.

Explanation:

To find the total travel time one way, we need to add up the time spent on each part of the journey. The salesman spends 1 hour and 48 minutes commuting from his house to the airport. Let's convert this to minutes, which gives us 60 + 48 = 108 minutes.



Next, we add the flight time. The question doesn't specify the duration of the flight, so we can't determine that. We'll assume it takes 2 hours, which is 120 minutes. Finally, we add the time spent on the bus. Again, the question doesn't provide this information, so let's assume it takes 1 hour (60 minutes) by bus.



Adding up the commute time, flight time, and bus time, we get 108 + 120 + 60 = 288 minutes. Therefore, the total travel time one way is 288 minutes.

The only solution of the equation x2 + bx + 16 = 0 is x = 4. What is the value of b?

b = –16
b = –8
b = 8
b = 16

Answers

b equals negative 8. becasue 16 is too large

Answer:

Option B is correct.

value of b = -8

Step-by-step explanation:

Given the equation: [tex]x^2+bx+16= 0[/tex]

As per the condition: The only solution for the given equation is, x = 4.

Substitute this value of x =4 in given equation, to solve for b;

[tex](4)^2+b(4)+16= 0[/tex]

Simplify:

[tex]16+4b+16= 0[/tex]

or

[tex]32 + 4b= 0[/tex]  

Subtract 32 on both sides, we get;

32 + 4b -32 = 0-32

Simplify:

4b = -32

Divide both sides by 4 we get;

b = -8

therefore, the value of b = -8

Solve for b 2(b-2)=2b+9

Answers

2(b-2)=2b+9
Distribute. 
2b-4=2b+9
Subtract 9 on both sides.
2b-13=2b
Subtract 2b on both sides.
-13=0
Because -13 is not equal to 0, there are no values of b that satisfy the equation.

A website-hosting service charges businesses a onetime setup fee of $275 plus d dollars for each month. If a business owner paid $1,091 for the first 12 months, including the setup fee, what is the value of d? a. Create an equation to represent this situation.

b.Solve your equation above to find the value of d. Show all work to receive full credit

Answers

(a) The total amount that is to be paid by the company is equal to the setup fee and the total fee collected for each month. The equation that can be used in order to determine the answer is,
      S = 275 + dx

where S is the total amount paid, d is the monthly fee and x is the number of months. Substituting the known values from the given,
    1091 = 275 + d(12)

or,   1091 = 12d + 275

(b) To determine the value of d, follow the steps given below,
    Substract 275 in each side of the equation,
    1091 - 275 = 12d + 275 - 275

Simplifying,
     816 = 12d 

    Divide both sides of the equation by 12,
      816/12 = 12d/12

Simplifying,
   68 = d
  
  or d = 68

Hence, d = 68

Suppose that you work part-time as a sales representative at a car dealership. You earn a base salary of $125 per week plus a 18% commission on all sales that you make. Your best friend has exactly the same job at another car dealership but earning a base salary of 85$ per week plus a 21% commission on all sales. How much do you and your friend need to sell in order to earn the same amount in any given week?

Answers

Define the two friends as person A and person B.

Let x =  the sales in a week.

Person A:
$125 per week plus 18% commission on sales.
Earnings in a week on x sales is
125 + 0.18x

Person B:
$85 per week plus 21% commission on sales.
Earnings in a week on x sales is
85 + 0.21x

For the two earnings to be equal,
85 + 0.21x = 125 + 0.18x
0.03x = 40
x = 40/0.03 = $1333.33

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image.

A line, called the line of reflection, will allow an image to reflect through it. Every element inside a figure is thought to reflect another figure when they are all equally spaced apart from one another.

As per the mentioned data in the question,

The given point is (5, 9).

Under the reflection in the y-axis, points are converted as,

(x, y) ⇒ (-x, y)

A rectangle has perimeter 84 cm and length 35 cm. What is its width?

Answers

P = 2(L + W)
84 = 2(35 + W)
84/2 = 35 + W
42 = 35 + W
W = 42 - 35
W = 7

answer
its width 7 cm

Answer:  The required width of the rectangle is 7 cm.

Step-by-step explanation:  Given that a rectangle has perimeter 84 cm and length 35 cm.

We are to find the width of the rectangle.

Let w represents the width of the rectangle.

According to the given information,

length, l = 35 cm and perimeter, P = 84 cm.

Therefore, we get

[tex]P=2(l+b)\\\\\Rightarrow 84=2(35+w)\\\\\Rightarrow 42=35+w\\\\\Rightarrow w=42-35\\\\\Rightarrow w=7.[/tex]

Thus, the required width of the rectangle is 7 cm.

If $2500 is invested at an interest rate of 4.5% per year, compounded daily, find the value of the investment after the given number of years. (round your answers to the nearest cent.)

Answers

$2500 is invested at an interest rate of 4.5% per year, compounded daily for 2 years will amount to $5225.

What is compound interest?

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

Given,  $2500 is invested at an interest rate of 4.5% per year, compounded daily, and assuming it is for 2 years.

∴ The amount compounded daily will be,

A = P(1 + (r/365)/100)ⁿˣ³⁶⁵ as compounded daily.

A = 2500(1 + (4.5/365)/100)²ˣ³⁶⁵.

A = 2500( 1 + 0.00101)⁷³⁰.

A = 2500(1.00101)⁷³⁰.

A = 2500×2.09 dollars.

A = 5225 dollars.

Final answer:

To calculate the future value of an investment of $2500 at a 4.5% interest rate compounded daily for 5 years, we use the compound interest formula. Assuming 5 years of growth, the future value would be approximately $3117.14.

Explanation:

If $2500 is invested at an interest rate of 4.5% per year, compounded daily, we need to find the value of the investment after a certain number of years. The formula to calculate the future value of an investment with daily compounding is given by:


FV = P × (1 + r/n)^(n×t)

where:

FV is the future value of the investment,P is the principal amount ($2500),r is the annual interest rate (4.5% or 0.045),n is the number of times the interest is compounded per year (365 for daily),t is the time the money is invested for, in years.

To calculate the future value, we plug in the values into the formula. However, the number of years, t, has not been specified, so we'll need that to give a final answer. For our purposes, let's assume the student asks for the value after 5 years. Using the formula:


FV = $2500 × (1 + 0.045/365)^(365×t)


FV = $2500 × (1 + 0.00012328767)^(1825)


FV = $2500 × 1.246856823


FV = $3117.14 (rounded to the nearest cent)

After 5 years, the investment would be worth approximately $3117.14.

Kim, Laura and Molly share £385
The ratio of the amount of money Kim gets to the amount of money Mollley gets is 2:5
Kim gets £105 less than Molly gets

What percentage of the £385 does Laura get ?

With working out

Answers

Set x equal to the amount of money Kim gets, and y for Molly's money.

 x = 2/5y, since the ratio is 2:5.
y = 105 + x, since Molly has 105 more pounds than Kim.

Substitute x into this equation, so that y = 105 + 2/5y. Subtract 2/5y from both sides to get 3/5y = 105. Divide each side by 0.6 (equivalent to 3/5) and you get y = 175, which is how much Molly has. Kim gets 2/5 of Molly's share (or 105 fewer pounds), so she has 70.

70 + 175 (Kim and Molly's shares) is equal to 245. Therefore, Laura receives the remaining 140 pounds.

140/385 = a/100
Cross multiply so that 385a is 14000. Divide by 385 to get 36.4 (rounded).

Thus, Laura receives about 36.4% of the total money. Hope this helps (:

To factor the expression x² - a completely, we need to write it as a product of two binomials.

This can be done using the difference of squares formula, which states that a² - b² = (a + b)(a - b).

If we apply this formula to x² - a, we get:

x² - a = (x + sqrt(a))(x - sqrt(a))

This is a factorization of x² - a into two binomials, where the constant term a is represented by the square root of a.
