Answer:
He'll end up paying 5,382 more than he borrowed.
Step-by-step explanation:
12 months in one year right so multiply 10 by 12.
You get 120 months in 10 years. Multiply $179.85 times 120 months.
Then you'll get the total amount he'll end up paying in those 10 years which is 21,582.
Subtract 21,582-16,200 and you get the amount of how much more money he'll end up paying which $5,382.

4. Your job as a carpenter pays $20/hour and you worked 40 hours last week. The taxes
withheld from your wages were $83 federal tax and $19 state tax. Your total check is
a. $698
b. $720
c. $810
d. $912
Answer:
698.00 (A)
Step-by-step explanation:
20.00x40=800.00
83.00+19.00=102.00
800.00-102.00=698.00
The total amount of the check will be $698. Then the correct option is A.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Your job as a carpenter pays $20/hour and you worked 40 hours last week.
Then the amount that you earn in 40 hours will be
⇒ $20 x 40
⇒ $800
The taxes withheld from your wages were $83 federal tax and $19 state tax. Then the total amount of the check will be
⇒ $800 - $83 - $19
⇒ $800 - $102
⇒ $698
The total amount of the check will be $698. Then the correct option is A.

If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2
Answer:
A) 12-10
B)36+225
Step-by-step explanation:
A) 3x4=12, 5x2= 10= 12-10
B) 3x2=6x6=36, 3x5=15x15=225=36+225
For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.
What is substitution?Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.
When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.
Given, x = 3 and y = 5.
∴ 4x - 2y is,
= 4(3) - 2(5).
= 12 - 10.
= 2.
And
2x² + 3y².
= 2(3²) + 3(5²).
= 2(9) + 3(25).
= 18 + 75.
= 93.

1). What is the perimeter of the triangle?
с
5 mm
12 mm
Answer:
30
Explanation:
To begin, first find the length of the third side of the triangle. We are given that the two short sides of the triangle have lengths of 5 and 12. Use the Pythagorean Theorem to find the length of the third side:
a2+b2=c2,
where a and b represent the two shorter sides of the triangle, and c is the hypotenuse:
a2+b2=c2
52+122=c2
25+144=c2
169=c2
169−−−√=c2−−√
c=13
Now that we have the lengths of all three sides, add them together to find the perimeter:
5+12+13=30
The perimeter of the triangle is 30.
How would you define slope?
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.
Which equation shows the relationship 30% of 140 is x?
Answer:
Step-by-step explanation:
[tex]equation: \frac{x}{140} = \frac{30}{100} \\reduced: 100x = 4200\\ solved: \frac{100x}{100} = \frac{4200}{100} \\x = 42[/tex]
An equation is formed of two equal expressions. The equation that shows the relationship 30% of 140 is x is x=0.30×140.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that 30% of 140 is equal to x. Therefore, we can write,
[tex]\text{30\% of 140} = x\\\\\dfrac{30}{100} \times 140 = x\\\\x = 0.30 \times 140\\\\x=42[/tex]
Hence, the equation that shows the relationship 30% of 140 is x is x=0.30×140.

)Suppose is a real number with 0 < < 4 . Set = sin( − ), = cos( + ), = sin( − ), and = cos(2 − ). Arrange the values , , , and in increasing order, and explain how you determined their order.
Answer:
b < c < a < d
Step-by-step explanation:
P.S - The exact question is -
Given - Suppose x is a real number with 0 < x < [tex]\frac{\pi }{4}[/tex] . Set a = sin([tex]\pi[/tex] - x) ,
b = cos([tex]\pi[/tex] + x) , c = sin( x - [tex]\pi[/tex]) , d = cos(2[tex]\pi[/tex] - x)
To find - Arrange the values of a, b, c, d in increasing order , and explain
how you determined their order.
Proof -
Firstly draw a unit circle where you indicate the following
A = ( cos(x), sin(x) )
B = ( cos( [tex]\pi[/tex] - x) , sin ([tex]\pi[/tex] - x) )
C = ( cos([tex]\pi[/tex] + x), sin ([tex]\pi[/tex] + x) )
D = ( cos (2[tex]\pi[/tex] - x) , sin (2[tex]\pi[/tex] - x) )
As we have given that 0 < x < [tex]\frac{\pi }{4}[/tex]
⇒sin (x) and cos(x) are positive and sin(x) < cos(x)
The figure is as follows :
Now
By seeing point B , we can say that
sin ([tex]\pi[/tex] - x) = sin (x) = a
By seeing point C , we can say that
cos([tex]\pi[/tex] + x) = -cos (x) = b
By seeing point C , we can say that
sin( x - [tex]\pi[/tex]) = -sin(x) = c
By seeing point D , we can say that
cos(2[tex]\pi[/tex] - x) = cos(x) = d
As sin(x) < cos(x) ⇒ a < d
-sin(x) > -cos(x) ⇒ c > b ⇒ b< c
and as we know that -sin(x) < sin(x) ⇒ c < a
∴ we get
b < c < a < d

Answer:

Well look at it this way.
It will just a smaller piece of something but never everything. For example 1/8 of 1/100000 is still going to be a number. So, it will never sell all video games. This is a mathematical perspective, not a logical perspective since logically you cant sell a part of a video game.

Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At sunset, the temperature was -5 degrees Fahrenheit. How many hours will it take for the temperature to reach -19° F?
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
[tex]-5+x(-2)=-19[/tex]
Where we taking 2 negative because temperature decreases.
[tex]-5-2x=-19[/tex]
[tex]-5+19=2x[/tex]
[tex]14=2x[/tex]
[tex]x=\frac{14}{2}[/tex]
[tex]x=7[/tex]
Hence, it will take 7 hours for the temperature to reach -19° F.

1. Explain the slope y-intercept
2. Is it a function ? Explain
3. Under what conditions could the slope be positive? Explain
Answer: 1) The y-intercept seems to mean that if the price is 0, there would be 225 "sold" (given away). As the price increases, the number sold decreases.
2.) It is a function. For each x-value, price, there is a unique y-value. This graph passes the "vertical line test."
3.) The slope could be positive if "perceived value" correlates with the price of the item. People may be willing to buy more if they believe that the higher price means higher quality, better performance, longer lasting, etc.
Step-by-step explanation:
The equation of this graph is y= -25x +225
where the x represents the price and y represents the number sold.
For every unit increase in price, 25 fewer items are sold.
Regarding question 3: The slope might not be as steep, but it could be positive when people are attracted to brand names with reputations for higher quality, or simply because they trust the brand name and are willing to pay more. Or the packaging and advertising are more attractive!
