Algebra Mathematics
Question 1
Mr Brown has several models of famous people that each weigh the same. He decides to add in some new models that are of different weights to his old ones. In Room Number One, there are five old models along with a new model that weighs 240kg.
In Room Number Two, there are 3 old models along with a new model that weighs 510kg.
THE TOTAL WEIGHT OF THE MODELS IN ROOM ONE IS EXACTLY THE SAME AS THE TOTAL WEIGHT OF THE MODELS IN ROOM TWO.
What is the weight of an old model?
Answer:
135kg
Step-by-step explanation:
In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.
the equation will be as: 5x + 240 = 3x + 510
move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240
which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

A spinner has many equal sections of different colors. The probability that the spinner will not land on a
blue section is 34%. What is the probability that the spinner will land on a blue section?
A 34%
B 66%
C 68%
D can’t be determined
Answer:
B 66%
Step-by-step explanation:
100% (total) - 34% (P(not landing on blue)) = 66%
You are parasailing for the first time. The rope that connects you to the boat is 38 feet long. The distance along the water between the boat and you is 22 feet. About how high above the water are you?
Answer:
About 30.98386677 ft above the water.
Step-by-step explanation:
Use pythagorean theorem, a^2+b^2=c^2.
So when you plug in the numbers it would be x^2+22^2=38^2. Move 22^2 to the right side giving you x^2=38^2-22^2. Then subtract and take the square root of x^2.
Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?
Answer:
$1200
Step-by-step explanation:
You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.
InterestThe interest formula is ...
I = Prt
where P is the amount borrowed, r is the interest rate, and t is the number of years.
ApplicationUsing the given values, we have ...
86.40 = P·0.072·1
P = 86.40/0.072 . . . . . . divide by the coefficient of P
P = 1200
You have borrowed $1200.
Answer: 1200
Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200

Answer: The table on the left is s direct variation. The equation is y = x/2
The table on the right is indirect.
Step-by-step explanation:
See if the output y changes by the same amount for each x-value. The equation describes the amount of change for the values you see and predicts the ones you can't see.
How do you solve this?
Answer:
21. D = 5.67(rounded to the hundredths)
R = 2.84(rounded to the hundredths)
22. D = 13.4
C = 42.08(rounded to the hundredths)
23. C = 33.28(rounded to the hundredths)
R = 5.3
24. D = 1
R = 1.57 or pi/2
Step-by-step explanation:
Formula: C/pi = D
D = 2r
pi = 3.14
21. D = 17.8/3.14 = 5.67(rounded to the hundredths)
R = 5.67/2 = 2.84(rounded to the hundredths)
22. D = 6.7*2 = 13.4
C = 13.4 * 3.14 = 42.08 (rounded to the hundredths)
23. C = 10.6 * 3.14 = 33.28(rounded to the hundredths)
R = 10.6/2 = 5.3
24. D = 3.14/3.14 = 1
R = 3.14/2 = 1.57 or pi/2

Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)
Inez says you can plot 40 on a number line, but Jeremiah says you cannot. Who is correct?
Use the drop-down menus to explain your answer.
(Inez or Jeremiah) is correct because any number divided by zero is (undefined or equal to 0) and (can or cannot) be represented on a number line.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Answer:
Equation B!
Step-by-step explanation:
If she ate, 2/3 of her pastry, and 1/5 later, and its asking you the total amount of pastry she ate. The equation would be 2/3 + 1/5, and if you would solve that, you would get the answer 13/15! So the full equation is 2/3 + 1/5= 13/15 , which is equation B!

Now we have to,
→ Find the required value of x.
Let's find the value of x,
→ 21/35 = 18/x
→ 21x = 18 × 35
→ 21x = 630
→ x = 630/21
→ [ x = 30 ]
Hence, the value of x is 30.
