One pack of pencils currently costs $1.19. The cost of one pack of pencils is projected to increase by 135% in the next 5 years. What is the projected cost of a pack of pencils 5 years from now? (Round your answer to the nearest cent.)

Answers

Answer: $2.80

Step-by-step explanation:

Given: Cost of one pack of pencils = $1.19

The cost of one pack of pencils is projected to increase by 135% in the next 5 years.

So, the cost of pack of pencils after 5 years = $1.19 + 135% of $1.19

= $ (1.19+1.35(1.19)) [135% = 1.35 since we divide each percent by 100 to convert in decimal]

= $ (1.19+1.6065 )

= $ 2.7965 ≈ $ 2.80 [Rounded to the nearest cent]

hence, the projected cost of a pack of pencils 5 years from now = $2.80

What are the values of m and d in the equation y = mx + such that the linear
function is its own inverse, and m is positive?
M=?
B=?

Answers

Answer:

The correct equation would be y=mx+b when trying to figure out the y-intercept and the slope of a coordinate. M would be the slope and b would be the y-intercept. For example, if the slope were to be 3 and the y-intercept would be 5, the equation would be, y=3x+5. I don't know if I helped but I hope I did!

The value is of the m and b such that equation y = mx + b is its own inverse will be 1 and 0 respectively.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

Given the linear b,

y = mx + b

Now inverse of this;

x = my + b

my = x - b

y = (1/m)x - b/m

Now,

For both functions equal

m = 1/m and -b = b

So m must be 1 and b must be 0.

Hence "The value is of the m and b such that equation y = mx + b is its own inverse will be 1 and 0 respectively.".

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe. Write an equation representing the cost, y, of renting a canoe for x hours. What is the cost of renting the canoe for 6 hours?

Answers

Answer:

use slope intercept form to write the equation y=mx+b m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.

y=30x+20

to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x

y=(30×6)+20

y=180+20=$200

Examine the diagram, where quadrilateral MNOP is inscribed in ⨀C such that m∠P=(2x)∘ and m∠N=(2x−12)∘.

What is the measure of m∠P and m∠N?

m∠P=96∘, m∠N=84∘
m∠P=84∘, m∠N=72∘
m∠P=90∘, m∠N=90∘
m∠P=72∘, m∠N=108∘

Answers

Answer:

Option (1)

Step-by-step explanation:

Since quadrilateral MNOP is a cyclic quadrilateral, sum of opposite angles of the quadrilateral will be 180°.

m∠P + m∠N = 180°

(2x)° + (2x - 12)° = 180°

4x - 12 = 180

4x = 192

x = 48

Therefore, m∠P = (2x)° = 2×48 = 96°

m∠N = (2x - 12)° = (2×48) - 12 = 84°

Option (1) will be the answer.

1) False
2) If two angles are 45 degrees then they are complementary and congruent.

Explanation: Complementary angles add up to 90 degrees and congruent angles are angles that are equal. Two 45 degree angles are equal to each other and add up to 90 degrees. The first statement is false because there are many combinations of angles that add up to 90 degrees that are not the same. (30 degrees and 60 degrees)

In ΔHIJ, \text{m}\angle H = (4x+1)^{\circ}m∠H=(4x+1) ∘ , \text{m}\angle I = (2x-6)^{\circ}m∠I=(2x−6) ∘ , and \text{m}\angle J = (6x-7)^{\circ}m∠J=(6x−7) ∘ . Find \text{m}\angle J.M∠J.

Answers

Given:

In ΔHIJ, m∠H=(4x+1)° , m∠I=(2x−6)°, and m∠J=(6x−7)° .

To find:

The m∠J.

Solution:

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.

In ΔHIJ,

[tex]m\angle H+m\angle I+m\angle J=180^\circ[/tex] [Angle sum property]

[tex](4x+1)^\circ+(2x-6)^\circ+(6x-7)^\circ=180^\circ[/tex]

[tex](12x-12)^\circ=180^\circ[/tex]

[tex]12x-12=180[/tex]

Add 12 on both sides.

[tex]12x=180+12[/tex]

[tex]12x=192[/tex]

Divide both sides by 12.

[tex]x=16[/tex]

Now,

[tex]m\angle J=(6x-7)^\circ[/tex]

[tex]m\angle J=(6(16)-7)^\circ[/tex]

[tex]m\angle J=(96-7)^\circ[/tex]

[tex]m\angle J=89^\circ[/tex]

Therefore, the measure of angle J is 89 degrees.

24-10b=9 what is the missing variable equal to

Answers

Answer:

b = 1.5

Step-by-step explanation:

Lets first set up the equation:

24 - 10b = 9

Okay now lets add 10b on both sides:

24 = 9 + 10b

Now let's subtract 9 from both sides so we can get the variable b by its self:

15 = 10b

Okay now we can divide each side by 10:

1.5 = b

Answer:

24-10(1.5)=9

b = 1.5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

b = 3 /2

Decimal Form:

b = 1.5

10(1.5) = 15

24 - 15 = 9

#12: Kara is deciding between The Lyme Point Inn and Ever After Farms for her wedding reception. The Lyme Point Inn charges $3,000 for the venue and $100 for each meal. Ever After Farm charges $5,400 for the venue and $70 for each meal. Write and solve an equation to find the number of meals at which the total cost charged by the two venues would be the same. *

Answers

Answer: Required euqtaion: 3000+100x = 5400+70x

Solution: x=80 i.e. The number of meals at which the total cost charged by the two venues would be the same = 80

Step-by-step explanation:

Let x= Number of meals.

For Lyme Point Inn, cost for x meals = 100x

Total cost = 3000+100x

For Ever After Farm, cost for x meals = 70x

Total cost = 5400+70x

When both cots same, then

3000+100x = 5400+70x

⇒ 100x-70x= 5400-3000

⇒ 30x=2400

⇒ x= 80

Hence, the number of meals at which the total cost charged by the two venues would be the same. =80

Which equation describes the line parallel to y = –7x + 15 that contains P(9, –6)?

Answers

Parallel means same slope. So you have to use point slope form. (x1,y1) is (9,-6) and the slope is -7

So it would be

y-(-6)=-7(x-9)

y+6=-7x+63

Solving for y gives you

y=-7x+57
