Find the measure of angle b.

Answer:

a. Profit from each book = $15

b. No, Travis was wrong.

c. Travis isn't correct because Mr. Roberts made $15 from the sales of each book.

Step-by-step explanation:

Given the following data;

Number of books bought = 500

Selling price = $35

Robert savings (cost price) = $9,512 + $488

Robert savings (cost price) = $10,000

Purchasing price = $10,000/500 = $20

Revenues from book sold = 500 * 35 = $17,500

Total profit = Revenues - Cost price

Total profit = $17,500 - $10,000

Total profit = $7,500

To find the amount earned from each book;

[tex] Profit \; from \; each \; book = \frac {Total \;profit}{Numbers \; of \; book} [/tex]

Substituting into the equation, we have;

[tex] Profit \; from \; each \; book = \frac {7500}{500} [/tex]

Profit from each book = $15

Therefore, Mr. Roberts earned $15 from selling each book.

Check:

Selling price = purchasing price + profit = $20 + $15 = $35

8a+8+5a−6

=8a+8+5a+−6

=8a+8+5a+−6

=(8a+5a)+(8+−6)

=13a+2

=> (8a + 8) + (5a – 6)

=> (8a + 5a) + (8 – 6) [Combine like terms]

=> (13a + 2)

Answer:

Why?:

The interest formula is A = P(1+r/m)^mt

A is the Amount, P is principal (initial investment), R is rate, M is times per year (not used) and T is time.

So if we want 1000 = 800(1+r)^4, we need to find R. In this case, R is about 5 percent.  (I'm not super confident, so see if you have other answers)

Answer:

  c = 17.8, A = 25.7°, B = 64.3°

Step-by-step explanation:

Side c can be found from the Pythagorean theorem:

  c = √(a² +b²)

  c = √(7.7² +16²) = √315.29

  c ≈ 17.8 . . . feet

__

The tangent relation is ...

  Tan = Opposite/Adjacent

  tan(A) = a/b = 7.7/16

  A = arctan(7.7/16)

  A ≈ 25.7°

  B = 90° -25.7°

  B = 64.3°

Answer:

  2876 books

Step-by-step explanation:

If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...

  y1 = 12841 +24.25x

  y2 = 48072 +12x

These costs will be equal when ...

  y1 = y2

  12841 +24.25x = 48072 +12x

  12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x

  x = 2876 . . . . . . . . . . divide by 12.25

The costs will be the same for production of 2876 books.

Answer:

About 46 pples

Step-by-step explanation:

Answer: 35

the age of Roberto is x (x > 3)(x ∈ N)

because Roberto is 3 years older than Carolyn => the age of Carolyn is x - 3

in 7 years, the age of Roberto is x + 7; the age of Carolyn is x - 3 + 7 = x + 4

because  In 7 years the sum of their ages will be 81 =>

x + 7 + x + 4 = 81

⇔ 2x + 11 = 81

⇔ 2x = 70

⇔ x = 70/2 = 35

=>  the age of Roberto is 35

Can you add how much money is in the problem for each of the 2 clubs for 3, 8 and 12 months? Then people will help you I think

The expressions to represent the costs of each club is $10 + ($15 * m)

Let's begin by writing expressions for the costs of each club:

Multiplayer Madness:

Joining Fee: $50 (one-time payment)

Monthly Fee: $0 (since it's not mentioned, we assume there's no additional monthly fee)

The total cost for Sharleen to join Multiplayer Madness would be the joining fee only, which is $50.

Games Galore:

Joining Fee: $10 (one-time payment)

Monthly Fee: $15 (recurring monthly charge)

The total cost for Sharleen to join Games Galore would be the joining fee plus the cumulative monthly fees over time. Let's represent the total cost of Games Galore as a function of the number of months (m) Sharleen stays in the club:

Total Cost of Games Galore = Joining Fee + (Monthly Fee * Number of Months)

Total Cost of Games Galore = $10 + ($15 * m)

Complete Question:

Your friend Sharleen is thinking about joining an online gaming club. She's trying to decide between Multiplayer Madness and Games Galore. Her brother insists that Multiplayer Madness is a better deal. Multiplayer Madness charges a joining fee of $50. It's a bit more expensive than Games Galore, a club that charges a $10 joining fee. But, Games Galore charges a fee of $15 a month. That's $5 more each month than the fee charged at Multiplayer Madness! Checklist Did You... Write expressions to represent the costs of each club?

1.option D and 2 is option D too

Answer:

Y=1x-7

Step-by-step explanation:

First use two points to find the slope. I used the first 2. The formula is (y1-y2)/(x1-x2). So (6-8)/(1-3)= -2/-2 = 1. Then you plug in a point and the slope for the equation y1-y2=m(x1-x2). I am using the first point and m is the slope which is 1. Y-6 = 1(x-1)

y-6 = 1x -1 then get y by itself

y=1x-7

Answer: 1.1818^37 kg

Step-by-step explanation:

Given that:

Orbit speed = 1300 km/s

Radius (r) = 18 light days

Mass of object the star is orbiting :

Using the relation :

M = rv² / G

Where ; r = Radius in m ; v = velocity in m/s

G = 6.67 * 10^-11 = gravitational constant

18 light days in meters = 4.662 * 10^14 m

v = 1300km/s to m/s

v = (1300 * 1000)m /s = 1300000 m/s = 1.3 * 10^6 m/s

Hence ;

M = (4.662 * 10^14 * (1.3 * 10^6)^2 / (2/3) * 10^-10

M = (4.662 * 10^14) * (1.69 * 10^12) / (2/3) *10^-10

M = (7.87878 * 10^26) / 6.67 * 10^-11

= 1.1818^37 kg

Step-by-step explanation:

If y=mx+b, m is the slope and b is the y-intercept.

If we replace the variables with y=-2x+1, we can see -2 is the slope and the y-intercept is (0,1).

Answer:

The equation of the given situation is y = 15x + 50

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

∵ A caterer charges $275 for 15 people

∵ A caterer charges $425 for 25 people

∵ x represents the number of people

∵ y represents the cost

∴ (x1, y1) = (15, 275)

∴ (x2, y2) = (25, 425)

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{425-275}{25-15}=\frac{150}{10}[/tex]

∴ m = 15

→ Substitute it in the form of the equation above

∴ y = 15x + b

→ To find b substitute x by 15 and y by 275

∵ 275 = 15(15) + b

∴ 275 = 225 + b

→ Subtract 225 from both sides

∴ 275 - 225 = 225 - 225 + b

∴ 50 = b

→ Substitute it in the equation

∴ y = 15x + 50

∴ The equation of the given situation is y = 15x + 50
