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.)
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

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.
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.

Sergio has *p* paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. Each of the 12 collectors will donate the same number of paintings. How many paintings will Sergio have in his art collection after his donation?
Answer:
p-4
Step-by-step explanation:
Sergio has p paintings in his art collection
He and other local painting collectors donated 48 paintings to the local museum
There are 12 collectors
Therefore each of them will donate
= 48/12
= 4 paintings
Since there are p paintings then the paintings in which Sergio will have in his art collection after donation is p-4
Answer:
p-4

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=?
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.".

The cost of a school lunch is $2.50. Complete the table to show the total cost of 1, 2, 3, and 4 lunche
Step-by-step explanation:
If 1 lunch =$2.50
2 lunches = $5.00 (2.50x2)
3 lunches =$7.50
4 lunches =$10.00
5 lunches= $12.50
basically just add $2.50
Using the multiplication principle, the completed table is shown below :
Quantity ___ cost 1 _________ 2.502 ________ 5.003 ________ 7.504 ________ 10.00The total cost for any quantity given can be obtained by taking the product of the quantity and the cost per lunch ;
Hence, the cost of quantities 1, 2, 3, and 4 are $2.50, $5.00, $7.50 and $10.00 respectively.

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∘
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.

Segments AB and CD intersect to form an angle of 89 degrees as shown. What is the measure of <2
Answer:
180-89= 91
Step-by-step explanation:
Answer:
2 = 91
Step-by-step explanation:
Angle 2 and the 89 degree angle are supplementary (They both add up to 180) because they form a straight line. So, you would do as follows:
180 - 89 =

Lawrence is making a pillow that has a five-sided design. The sides measure 18in, 12in 14 1/4in,12in and 14 1/4. What is the sum of the five sides of this pillow in simplest form
The sum of the 5 sides =
(18 + 12 + 14 1/4 + 12 + 14 1/4) inches
= 18 + 12 + 14+ 12 + 14 + (1/4 + 1/4)
= 70 (2/4)
= 70 1/2 inches
The sum of the five sides of this pillow in simplest form is 70 1/2 inches
#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. *
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

Lucy estimated that is would take 4000 grains of sand to make a pound. That would mean each grain of sand weighs 1/4000 of a pound. In a decimal form, each grain of sand would weigth 0.00025 pounds. Which number expressed in scienfic notation represent the weigth of a grain of sand?
Answer:
25x10^-5
Step-by-step explanation:
We are expected to represent the decimal number in scientific notation
the decimal number is 0.00025
Given that the number in decimal is 0.00025 pounds
in scientific notation we will have to count 4 decimal point to the left from the second number which is 2
=2.5x10^-4
or we can still write it as
25x10^-5
either of the above is correct, only take note of the number of places you count and the sign
