-20 less than or equal to 2x -20 less than or equal to 30
Answer = 0 ≤ x ≤ 25
Explanation:
Break the word equation into two for better understanding
-20 less than or equal to 2x -20 >>>> -20 ≤ 2x -20
2x -20 less than or equal to 30 >>>> 2x -20 ≤ 30
Keeping in view the question we deduce the equation
-20 ≤ 2x -20 ≤ 30
Solve and simplify the above equation accordingly, by breaking down the equation
-20 ≤ 2x -20 and 2x -20 ≤ 30
-20+20 ≤ 2x and 2x ≤ 30 +20
0 ≤ x (0/2) and x ≤ 25 (50/2)
So, 0 ≤ x ≤ 25

F(n) = 900 - 60(n-1) represent the amount oscar still need to repay on a loan at the beginning of month n .Find the amount oscar pays monthly and the month in which he will make his last payment.
Answer:Each installment will be of 60 and 16th will be the last payment.
Step-by-step explanation:
To find the monthly repayment by Oscar we first find the sequence.
For that first we put [tex] n=1 [/tex] in
[tex] F(n)=900-60(n-1)[/tex]
[tex] F(1)= 900-60(1-1) = 900 [/tex]
Now for [tex]n=2 [/tex]
[tex] F(2)=900-60(2-1)=840[/tex]
For [tex]n=3[/tex]
[tex] F(3)=900-60(3-1)=900-120=780[/tex]
So the sequenxe is 900,840,780......
As the amount is decreasing by 900-840=840-780=60
Therefore each installment will be equal to 60
For last payment amount will become 0
i.e.[tex]F(n) =0[/tex]
[tex] 900-60(n-1)=0[/tex]
[tex] 900-60n+60=0 [/tex]
[tex] 960=60n [/tex]
[tex]n = 960\div60[/tex]
[tex]n = 16 [/tex]
Last month will be 16th
The amount Oscar pays monthly is $900, and he will make his last payment in month 16.
Explanation:To find the amount Oscar pays monthly, we can subtract the amount he repays in each month from the previous month's balance. The formula F(n) = 900 - 60(n-1) represents the remaining amount Oscar needs to repay at the beginning of month n. By plugging in n = 1, we can find the initial balance and the amount he paid that month. To find the month in which he makes his last payment, we can set F(n) to zero and solve for n.

A piece of fabric is 1/3 yard by 3 5/8 yards. Irma solves 1/3⋅3 5/8 to find the area of the fabric in square yards. Enter numbers to complete irma's calculation for the area.
For this case we have:
The area of the piece of fabric is given by [tex]A = a * b[/tex]
Where
[tex]a = \frac{1}{3}yards[/tex]
[tex]b = 3 \frac{5}{8}yards[/tex]
Substituting in the formula of the area we have:
[tex]A = \frac{1}{3}* 3 \frac{5}{8}\\[/tex]
[tex]A = \frac{1}{3}* (3 + \frac{5}{8})\\[/tex]
[tex]A = 1 + \frac{5}{24}[/tex]
[tex]A = 1\frac{5}{24}yards ^ 2\\[/tex]

Factor the expression over the complex numbers.
x2+25
Answer:(x+5i) (x-5i) is the right answer
The expression x^2 + 25 can be factored over the complex numbers as (x + 5i) and (x - 5i). This is achieved using the sum of squares formula a^2 + b^2 = (a + bi)(a - bi).
Explanation:The expression you are tasked with factoring is x2 + 25.
This is a sum of squares expression and can be factored using the formula a2 + b2 = (a + bi)(a - bi), where 'i' represents the complex numbers.
So, x2 + 25 can be factored as (x + 5i)(x - 5i).
This is because the square root of 25 is 5, and 'i' represents the imaginary number.
So the factors of the expression x2 + 25 over the complex numbers are (x + 5i) and (x - 5i).

Why do the ratios of sine and cosine depend upon the angle being a part of a right triangle?
Step-by-step explanation:
Think of a right triangle (refer the attached image). If you increase or decrease the length of one of its legs, while keeping the other leg the same (the hypotenuse will increase as well) here we have increased the length of the perpendicular side. You can see that the *subtending* angle (the angle which is opposite to the increasing leg, x) gets larger, while the *adjacent* angle (the angle with the increasing leg as one of its rays) will decrease.
and we know that:
[tex]\sin x=\frac{AB}{AC}[/tex] and [tex]\cos x=\frac{BC}{AB}[/tex] in both the cases the variation of AB is causing the angles to change hence, the ratios of sine and cosine depend upon the angle being a part of a right triangle.

Nuclear power provided 78% of the energy used in france in 2005. Write 0.78 as a fraction in simplest form.
Here we are given first that Nuclear power provided 78% of the energy used in france in 2005.
Now this was written in decimal as 0.78.
Then we have to write it in fraction form.
So first we have here two digits after the decimal, so in denominator we will have 100,
[tex]\frac{78}{100}[/tex]
Now we have to convert this into simplest form.
For that we have to find HCF of 78 and 100.
The HCF of 78 and 100 is 2, so we will divide both numerator and denominator by 2,
[tex]\frac{78/2}{100/2}[/tex]
This gives us:
[tex]\frac{39}{50}[/tex]
Answer: The simplest form of 0.78 as as fraction is 39/50.

Ruben bought 6 new book which increased his collection by 12%. How many books did he have?
Answer:
The initial number of books he had=50
The number of books he has after adding new books=56
Step-by-step explanation:
Step 1: Derive formula for percentage increase
The formula for calculating the percentage increase is;
p={(f-i)/i}×100
where;
p=the percentage increase
f=the final number of books he had
i=the initial number of he had
In our case;
p=12%
(f-i)=defines the increase in the number of books=6
i=unknown
Substitute and solve for i;
12%=6/i
(12/100)=6/i
(12/100)×i=6
i=6×100/12
i=50
The initial number of books he had=50
The number of books he has after adding new books=50+6=56

Which of the following equations describes a line with an x-intercept of 3? A. x + y = −3 B. x − y = −3 C. x = 3
The correct equation which describes a line with an x-intercept of 3 is C. x = 3. This implies a vertical line where the x-value is always 3, regardless of the y-value.
Explanation:In response to your query about which of the following equations describes a line with an x-intercept of 3, the direct answer is C. x = 3. An x-intercept is the point where a line crosses the x-axis. For an equation to have an x-intercept of 3, it means that when y is 0, x equals 3. By plotting this on a graph, y can be any real number, but x will always stay 3. Therefore, the equation x = 3, which option C represents, is the correct description for a line with an x-intercept of 3.
It's important to note that, in terms of linear equations (generally represented as y = mx + b, where m represents the slope and b represents the y-intercept), x = 3 can be perceived as a vertical line that intersects the x-axis at point 3.

the perez family has a rectangle fish tank. How much water will the tank hold if its length is 3 feet, its width is 2 feet, and its high is 3 feet
Hello there
Since there is 1 foot water in the tank the total volume = 3*2 * 1
= 6 cubic feet.
volume of 6 cu. feet corresponds to 1 foot of water in height, this will help you find your answer
The Perez family's rectangular fish tank can hold 18 cubic feet of water by multiplying the length, width, and height (3ft x 2ft x 3ft).
To calculate the amount of water the Perez family's rectangular fish tank can hold, we use the formula for the volume of a rectangle, which is length * width * height.
Given:
Length (l) = 3 feetWidth (w) = 2 feetHeight (h) = 3 feetThe volume (V) is calculated as:
V = l * w * h
V = 3 feet * 2 feet * 3 feet
V = 18 cubic feet
Therefore, the rectangular fish tank can hold 18 cubic feet of water.

What is the range of f(x)?

{ f(x)| –∞ < f(x) ≤ 4}
{ f(x)| 4 < f(x) < ∞}
{ f(x)| 0 ≤ f(x) < ∞}
Answer:
best ans is { f(x)| –∞ < f(x) ≤ 4}
Step-by-step explanation:
usually to find the range of a fn, u need to see what the value can be. the graph show only a small range of x values. but u can see f(x) is definitely < 4. so the ans is { f(x)| –∞ < f(x) ≤ 4}
The range of the graph will be (–∞, 4]. Then the correct option is B.
What are domain and range?The domain means all the possible values of x and the range means all the possible values of y.
From the graph, we can conclude that the curve gets saturated at y = 4 and as the value of x approached to infinity, the value of y approach to negative infinity.
The range of the graph will be (–∞, 4].
Then the correct option is B.

A company can produce as many as 50 mountain bikes and as many as...
The other constrain would be the number of hours it takes to make each one.
4 hours for a mountain bike would be 4x
5 hours for a road bike would be 5y
The hours need to be less than or equal to a total of 300 hours.
The missing constraint would be 4x + 5y ≤ 300.
Answer:
4x + 5y ≤ 300
Step-by-step explanation:
x: no of mt bike n y: no. of road bike
