In the equation a= 3/b is a positive, real number. As the
value of b is increased so it becomes closer and closer to
infinity, what happens to the value of a ?

Answers

Answer:

The value of a tends to zero

Step-by-step explanation:

Given the expression a = 3/b

as the denominator of the of the expression b increases the value of the output is known to be decreasing. if the value of b now goes so large to become an infinite, value then the value of a will goes to zero as shown;

If b = ∞

a = 3/∞

a = 0

Note that for any constant value a, the ratio a/∞ will always tends to zero

Avery is in the business of manufacturing phones. She must pay a daily fixed cost to
rent the building and equipment, and also pays a cost per phone produced for
materials and labor. The labor and materials cost $100 for each phone manufactured,
and the total cost of producing 3 phones in a day would be $600. Write an equation
for C, in terms of p, representing total cost, in dollars, of producing p phones in a
given day.
Answer: C=?

Answers

Answer:

The equation that represents the total cost in dollars is C = 100p + 300

Step-by-step explanation:

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

m is the slope ⇒ rate of changeb is the y-intercept ⇒ fixed amount

∵ Avery must pay a daily fixed cost to  rent the building and equipment

∴ There is a fixed amount b

∵ She pays a cost per phone produced for  materials and labor

∴ There is a rate m

C represents the total cost of producing p phones in dollars

→ Form the linear equation for the situation

∴ The equation is C = m p + b

∵ The labor and materials cost $100 for each phone

m = 100

→ Substitute it in the equation above

C = 100p + b

∵ The cost of producing 3 phones in a day would be $600

p = 3 and C = 600

→ Substitute them in the equation above to find b

∵ 600 = 100(3) + b

∴ 600 = 300 + b

→ Subtract 300 from both sides to find b

∵ 600 - 300 = 300 - 300 + b

300 = b

→ Substitute it in the equation

C = 100p + 300

The equation that represents the total cost in dollars is C = 100p + 300

solve the equation

it takes Louis 1 2/3 hours to write 5/6 of a short story how long will it take louis to complete the story?​

Answers

Answer:

2 hours to write the story.

1/3 of an hour remaining to complete the story.

20 minutes remaining.

(Read the explanation for further details.)

Step-by-step explanation:

1.Based on the given information, set up an equation;

(1 2/3) hours ; (5/6) story

Convert to improper fractions;

(1 2/3) ; (5/6)

(5/3) ; (5/6)

2. Solve;

(5/3) ; (5/6)

divide both sides by (5/6)

(5/3) ; (5/6)

/(5/6)   /(5/6)

Dividing a fraction is the same as multiplying by its reciprocal

(5/3)/(5/6) ; (5/3)/(5/3)

(5/3)*(6/5) ; (5/3)*(3/5)

2 ; 1

2 hours; 1 story

3. Solve for the time remaining;

Subtract the amount of time elapsed from that total amount of time

total time - time used

2 hours - 1 2/3 hours

Convert to improper fractions

2 - 5/3

1/3 hour

Convert to minutes

Combine terms:

[tex]x+\frac{1}{2}x=\frac{3}{2}x \frac{3}{2}x=315[/tex]

Write a system of equation for the following scenario.
Roshaun has saved $150 and continues to save $10 each week. Keegan starts with $0 and saves $25 each week.

Answers

Answer:

Let's start out with the amount of money each person will have over any period of time. Let t = time in weeks.

Roshaun will have 150 + 10t. Keegan will have 25t. we want to know when they will have the same amounts, so we set the 2 equations equal and solve for t:

150 + 10t = 25t

150 = 25t - 10t

150 = 15t

150/15 = t

10 = t

Therefore, in 10 weeks they will both have the same amount:

Roshaun: 150 + 10(10)--->150 + 100 = $250

Keegan; 25(10) = $250

Hope this helps!

Step-by-step explanation:

Please mark me as the brainliest answer and please follow me

to find the amount of savings roshaun and keegan will have, let x represent the no. of weeks.
total savings roshaun has = $150 + $(10x)

Can you explain to me how to solve this problem?

Answers

Answer:

110

Step-by-step explanation:

Ok so you will do 22 times 5 first

Which will be 110!

You can double check

110 divided by 5 is.. 22!

So it’s basically asking what number divided by 5 = 22
You want to move the variable to one side and the actual numbers to the other side of the equal sign.
When you move the number 5 to the right, you take the division sign with it, and when you move something, the sign in front of it becomes its opposite. The division sign will now become a multiplication sign.

Now the equation looks like this: r = 22 times 5
R would equal 110

Travis goes to the book fair where paperback books are $1.50 and hardback books are $3. Travis buys five paperback books and two hardback books. How much change will Travis receive from a $20 bill?

Answers

5x1.50 = 7.5
2x3 = 6

7.5 + 6 = 13.5
Change Travis will recieve
= 20 - 13.5
= $6.5

Using the appropriate arithmetic operations, the amount of change Travis is entitled to is :$6.50

Total cost of paper back books :

($1.50 × 5) = $7.50

Total cost of hardcover books :

($3 × 2) = $6

Total cost = $7.50 + $6.00 = $13.50

Change = $20 - $13.50 = $6.50

Therefore, Travis will get a change of $6.50

Some equations have the form y=kx, where k is a number.

Which equation CANNOT be written in the form y=kx?

y=x

y=x+3

y/2=x

y= ‐1/10x

Answers

Answer:

y=x+3

Step-by-step explanation:

The equation "y=x+3" cannot be written in the form y=kx because the form doesn't use addition as a basic operation. Let's try verifying the choices:

y=x is possible if the value of k is 1, provided that both y and x are of the same value.

y/2=x is possible because y=2x, provided that 2 is the value of k.

y=-1/10x is possible because -1/10 is the value of k. This is just the same with y=kx.

Here,
The slope of the function y =7x - 10 is m = 7, and the slope of the function in the graph is m = 6.
The intercept of the function in equation form is -10 while the intercept of the function shown in the graph is -6.

triangle ABC ~ triangle XYZ , where AB = 18 cm, BC = 30 cm , and CA = 42 cm . The longest side of triangle XYZ is 25.2 cm. What is the perimeter of triangle XYZ ?

Answers

Answer:

The perimeter of triangle XYZ is 54 cm

Step-by-step explanation:

In similar triangles, their corresponding sides are proportional, which means the ratios of the corresponding sides are equalTheir perimeters have the same ratio as their corresponding sides, which means P1 = r × P2, where r is the ratio of similarityTheir areas have the square of the ratio as their corresponding sides, which means A1 = r² × A2

Δ ABC is similar to Δ XYZ

∵ The longest side in Δ XYZ is 25.2 cm

→ That means its corresponding side in Δ ABC is the longest side

∵ AB = 18 cm, BC = 30 cm, CA = 42 cm

∴ The longest side in Δ ABC is CA

∴ CA is the corresponding side of the side of length 25.2 cm

The ratio of similarity = [tex]\frac{25.2}{42}[/tex] = 0.6 ⇒ (r)

∵ The perimeter of Δ ABC = AB + BC + CA

∴ The perimeter of Δ ABC = 18 + 30 + 42

∴ The perimeter of Δ ABC = 90 cm

→ Use the 2nd fact above

∵ P of Δ XYZ = r × P of Δ ABC

r = 0.6 and P of Δ ABC = 90

∴ The perimeter of Δ XYZ = 0.6 × 90

The perimeter of Δ XYZ = 54 cm
