You have a gift certificate to a book store worth $95. Each paperback books is $10 and each hardcover books is
$17. You must spend at least $20 in order to use the gift certificate. Write and graph a system of inequalities to
model the number of each kind of books you can buy. Let x = the number of paperback books and y = the number
of hardback books
Answer: You make a system of inequality to spend at least $20. The word "at least" means you can spend equal to $20 or higher than $20. Or you can write it as,
⇒ what you buy should be ≥ 20
Input the price to the inequality above
⇒ what you buy should be ≥ 20
⇒ paperback price + hardcover price ≥ 20
⇒ 10x + 17y ≥ 20
Because the number of paperback books and the number of hardcover books can't be negative, make new inequality forms
⇒ x ≥ 0
⇒ y ≥ 0
So this is the summary
10x + 17y ≥ 20
x ≥ 0
y ≥ 0

Use the diagram and the given angle measure to find the other three measures
The other three measures are:
∠1 = 159°∠2 = 21°∠4 = 21°What is Angle?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.This, I assume, refers to two lines that cross and create four angles.
The sum of the additional angles 2 and 3 is 180°.Angles 2 and 3 equal 180°.159⁰ + angle 2 = 180⁰angle 2 = 180⁰ - 159⁰angle 2 = 21⁰The same applies to angles 2 and 4 since angles 1 and 3 are vertical angles.
Since vertical angles are congruent in measure, it is simple to determine their measurements.

Ada lives 12 4/5 miles from her aunt's house. she lives 17 3/8 miles from her grandmother's house. how many more miles does jada live from her grandmother's house than her aunt's house?
Answer:
[tex]4 \frac{23}{40}\; \rm miles[/tex]
Step-by-step explanation:
To find how many more miles Ada lives from her grandmother's house than her aunt's house, we need to subtract the distance to her aunt's house from the distance to her grandmother's house.
Ada lives 17 3/8 miles from her grandmother's house.
Ada lives 12 4/5 miles from her aunt's house.
Convert both mixed numbers into improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:
[tex]17 \frac{3}{8}=\dfrac{17 \cdot 8+3}{8}=\dfrac{139}{8}[/tex]
[tex]12 \frac{4}{5}=\dfrac{12 \cdot 5+4}{5}=\dfrac{64}{5}[/tex]
As both improper fractions have a different denominator, we need to change both fractions into equivalent fractions with the same denominator. To do this, find the least common multiple (LCM) of the denominators, 8 and 5.
The LCM of 8 and 5 is 40. Therefore, convert the fractions into their equivalent fractions (with 40 as their denominator) by multiplying the numerator and denominator by the same number:
[tex]\dfrac{139}{8}=\dfrac{139 \cdot 5}{8 \cdot 5}=\dfrac{695}{40}[/tex]
[tex]\dfrac{64}{5}=\dfrac{64 \cdot 8}{5 \cdot 8}=\dfrac{512}{40}[/tex]
Now the fractions have the same denominator, we can carry out the subtraction by simply subtracting the numerators:
[tex]\dfrac{695}{40}-\dfrac{512}{40}=\dfrac{695-512}{40}=\dfrac{183}{40}[/tex]
Finally, convert the improper fraction into a mixed number by dividing the numerator by the denominator:
[tex]183 \div 40=4\;\rm remainder \;23[/tex]
The mixed number answer is the whole number and the remainder divided by the denominator:
[tex]4 \frac{23}{40}[/tex]
Therefore, Ada lives 4 23/40 miles more from her grandmother's house than her aunt's house.
each day for five days, you collect a sample of 200 buns coming out of a commercial oven. you record the number of burned buns in the table below. the standard deviation (sigma) is 0.025. what is the upper control limit? state your answer to two decimal places, for example 0.12
The upper limit is 0.79
The class interval's upper limit is its highest value. Similarly, the lower limit is the class interval's smallest value.
Given that n = 200 and standard deviation σ = 0.025
σ = (√n/√n) = 0.025
Now calculate p
P = defectives/total inspected
= 145/200
P = 0.72
Q= 1-p
= 1- 0.72
= 0.18
Now calculate the upper limit
UCL = p – (-3 x σ)
= 0.72 – ( -3 x 0.025)
= 0.72 – (-0.075)
= 0.72 + 0.075
= 0.795
= 0.79
Therefore the upper limit is 0.79

To compleate a task in 16 days a company needs 5 workers each working 6 hours per day
The company decides to have 8 people each working 4 hours per day
Assuming that each person works at the same rate
How many days will the task take to complete?
Answer:
10 days
Step-by-step explanation:
This is a type of proportion either direct or indirect .16 days for 5 workers.so for 8 workers the days will reduce .Now for 8 workers it will be 10daysSuzette ran and biked for a total of 50 mi in 4 h. Her average running speed was 5mph and her average biking speed was 15 mph.
Let x= total hours ran
Let y= total hours biked
How many hours did suzette run?
How many hours did she bike?
In total 4 hours Suzette ran for 1 hour and biked for 3 hours having average speed 5mph and 15mph respectively.
What is Average Speed?
Average speed is defined as total distance covered by the body divided by the time taken.
Average speed = Total distance covered/ total time taken
According to the given question:
Let x = total hours ran and y = total hours biked
Total time she ran and biked = 4h
∴ x + y = 4 ----- 1)
Total distance she biked and ran = 50 miles
Now, average running speed = 5 mph
Distance she ran = 5x
Similarly average biking speed = 15 mph
Distance she biked = 15y
∴ 5x + 15y = 50 ----- 2)
Solving 1) and 2) to get the values of x and y
Substituting x = 4 - y from 1) in 2)
5 (4 - y) + 15y = 50
On solving further we get y = 3
Substituting y = 3 to get x
x = 4 - 3
x = 1
Hence the Suzette ran for 1h and biked for 3h.

Using g as variable which is the number of games to be played we have
total amount gotten from games = 9 * g
prizes of winners = 207.35
The inequality equation as described in the problem is represented using linear function as as follows
9g - 207.35 > 100
for the owner to make more than 100 we have the equation
total amount gotten from games - prizes of winners > 100
9g - 207.35 > 100
100 + 207.35 < 9g
9g > 307.35
g > 34.15

The table represents points on a line. What is the slope
X 1 4 7 10
Y 8 6 4 2
Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 8) and (x₂, y₂ ) = (10, 2) ← 2 ordered pairs from the table
m = [tex]\frac{2-8}{10-1}[/tex] = [tex]\frac{-6}{9}[/tex] = - [tex]\frac{2}{3}[/tex]
