Answer:
Question 2: The first function represents the amount of money she'll have from her 450 under her bed.
s(x) = 450
The second function represents the amount of money she'll earn from babysitting per hour (x):
a(x) = 6(x - 2)
To figure the combined amount, we can add the two functions:
f(x) = s(x) + a(x)
f(x) = 450 + 6(x - 2)
From there, she can simplify the function by distributing, then combining the like terms to simplify:
f(x) = 450 + 6x - 12
f(x) = 438 + 6x
Answer:
f(x) = 438 + 6x
Question 4: His functions are;
h(x)=$350
s(x)=(1.04)^x-1
To find total amount of money in Tommy's account using the functions above, we substitute the first equation x=$350 in the second function.
simplify
(a^m/a^n)^m+n×(a^n/a^p)^n+p8×(a^p/a^m)^p+m
step by step
Answer:
m+a-1mn+m2+a-1np+n2n+a-mp+p2p8

From an 18-pound cut of meat, Mr. Rand cuts off steaks weighting 1 pound 15 ounces, 3 1/8 pounds, and 4 1/2 pounds. He divides up the rest into 9-ounces patties and sells them at 3 for $3.12. How much money does he receive for the patties?
Answer is in the picture
The amount of money received by him will be $15.60.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
The amount will be calculated as follows:-
The cut off amount = 18 - ( 1(15/16) -3(1/8)-4(1/2) = 8(7/16)
Now 16 ounces make a pound so divide by 16 we get:-
(135/16) ÷ ( 9 / 16 ) = ( 135/16 ) x ( 16 / 9 ) = 15
Dividing 15 by 3 we get 5 packs of 3 patties for $3.12
So amount = 3.12 x 5 = $15.60
Therefore the amount of money received by him will be $15.60.

Eva conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 3 hours. What does this range say about the data?
A. The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
B. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
C. All the students surveyed spend exactly 3 hours surfing the Internet.
D. All the students surveyed spend an average of 3 hours surfing the Internet.
Answer
The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
Explanation
The meaning of range is the difference between the largest and smallest numbers in a set.
In this case, it's possible that one of the students spends no time surfing the internet, and another student spends 3 hours. The range of the data would be 3. It's also possible that some students spend 20 hours surfing the internet, and other students spends 23 hours surfing the internet (although, that's obviously unreasonable).
Answer:
B. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.

Answer:
A) ≈ 6.93
B) ≈ 0.02
Step-by-step explanation:
A)
Formula : a² + b² = c²
2.4² + 6.5² = c²
5.76 + 42.25 = c²
c = √48.01
c ≈ 6.93
B)
Formula = c² - a² = b²
1/3² - 1/4² = b²
1/9 - 1/16 = b²
b = √7/144

y varies inversely as the square of x

Find y when x=5
Answer:
3.84
Step-by-step explanation:
Given that , y varies inversely as the square of x . Mathematically we can write this statement as ,
[tex]\implies\rm y \propto \dfrac{1}{x^2}[/tex]
Let k be the constant . Therefore ,
[tex]\implies\rm y = k \dfrac{1}{x^2}[/tex]

Plug in the respective values ,[tex]\implies\rm y = k \dfrac{1}{x^2} \\\\\implies\rm 1.5 = k \times \dfrac{1}{8^2} \\\\\implies\rm k = 1.5 \times 64 \\\\\implies\rm k = 96[/tex]
When x = 5 :-
[tex]\implies\rm y = k \dfrac{1}{x^2} \\\\\implies\rm y = 96 \times \dfrac{1}{5^2}=\dfrac{ 96}{25} \\\\\implies\rm\boxed{ y = 3.84 }[/tex]

What is the solution of the system of equations?
(12, 6)
(6, 12)
(9, 9)
(15, 3)
Answer:
12, 6
Step-by-step explanation:
we have two equations
x + y = 18 .... . (i)
and x = 2y .... .(ii)
substituting the value of x from eq. (ii) in eq. (i)
2y + y = 18
3y = 18
y = 6
putting this value if y in equation (ii) to get x
x = 2 × 6
= 12
therefore,
(12, 6) is the solution to the system of equations

Answer:
B) 28 inches.
Step-by-step explanation:
After 1/8 of a ribbon is thrown away, the remaining part is cut into two pieces whose lengths are in the ratio 4 : 5.
And we want to find the length of the shorter ribbon from the two remaining pieces.
We are given that 9 inches of the original ribbon was thrown away. Since this is 1/8 of the total length, we can write that:
[tex]\displaystyle \frac{1}{8}L=9[/tex]
Where L represents the total length of the ribbon.
Solve for the total length:
[tex]\displaystyle L=72\text{ inches}[/tex]
So, the original length of the ribbon was 72 inches.
Since we threw away 9 inches of it, we now only have 63 inches.
This is then cut into two pieces in a ratio of 4 : 5. Let x represent the constant. Thus:
[tex](4x)+(5x)=63[/tex]
Solve for x:
[tex]9x=63\Rightarrow x=7[/tex]
Hence, the two remaining ribbons measure 28 inches and 35 inches.
Therefore, our answer is B.
Help pls, can you solve for x?
Answer:
X=1.5, but I may be incorrect, hope this helps!
Step-by-step explanation:
FACTS I KNOW:
X has to be less than 2 but greater than 1
Angle B and D are 90 degrees
The complete bottom side is equal to 10
All triangle angles add up to 180 degrees
All angles in rectangles and squares are 90 degrees
All rectangles have 2 sets of 2 of the same sides.
If you take a piece of the top right you could make a rectangle
It would take about .5 of the 2
Therefore X=1.5 approximately, but I may be wrong.
You are writing a science research paper for your Chemistry class. You can type four pages per hour and you have already typed two pages. Write a function where t represents the number of hours and W(t) is the total pages written.
Answer: W(t) = 4t + 2
Step-by-step explanation:
y = ax + b
Because you have already typed two pages, the y-intercept(b) will be 2
The slope(a) is the number of pages typed per hour, which is 4.
So if you put it together:
W(t) = 4t + 2
