Hank: 1.3 pounds at a rate of 0.75 pounds per minute
Tom: 2.5 pounds at a rate of 0.5 pounds per minute
rate is given by
r = p / t
where p is the number of pounds picked during a fixed time
The number of berries picked by Hank during a certain time is given by the following equation
[tex]H=1.3+0.75t[/tex]For Tom, the equation is the following:
[tex]T=2.5+0.5\cdot t[/tex]Now, we need to find a time t when T and H are the same
[tex]\begin{gathered} H=T \\ 1.3+0.75t=2.5+0.5t \end{gathered}[/tex]We now just need to solve for t
Let's find t step by step
[tex]\begin{gathered} 1.3\cdot\: 100+0.75t\cdot\: 100=2.5\cdot\: 100+0.5t\cdot\: 100 \\ 130+75t=250+50t \\ 130+75t-130=250+50t-130 \\ 75t=50t+120 \\ 75t-50t=50t+120-50t \\ 25t=120 \\ \frac{25t}{25}=\frac{120}{25} \\ t=\frac{24}{5} \end{gathered}[/tex]Which is the same as t=4.8

Steve drives an electric car. He can drive 425 kilometres before he needs to stop and re-charge his car. It takes 10 minutes to charge 50 kilometres. How long does Steve have to wait for his car to fully charge?
Steve has to wait for 1 hour 25 minutes
Answer: 1 h 25 min
Step-by-step explanation:
Let us make the proportion:
10 min - 50 km
x min - 425 km
Hence,
[tex]\displaystyle\\x=\frac{425(10)}{50} \\\\x=\frac{85(5)(10)}{5(10)} \\\\x=85 \ min\\\\x=(60+25) \ min\\\\x=1\ hour\ 25\ min[/tex]

Use the following function rule to find f(–3a + 7). Simplify your answer.
f(b) = – 8b
f (–3a + 7) = ?
The functional value of f(-3a + 7) is 24a - 56
What is a function?
A rule that assigns a specific element of B to each element of A is known as a function from A to B. Both A and B are referred to as the function's domain and codomain, respectively. A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
There are different operations on functions like addition, subtraction, multiplication, division, and composition of functions.
Here we have,
the given function is
f(b) = -8b
f(-3a + 7) = -8(-3a + 7)
= 24a - 56
Hence, the functional value of f(-3a + 7) is 24a - 56

Given:
Exponential graph.
Find-: 1) Domain

Domain - The domain of a function is the set of its possible inputs, i.e., the set of input values where for which the function is defined. In the function machine metaphor, the domain is the set of objects that the machine will accept as inputs.
The input value is shown in the x-axis so in given graph possible value of x is:

Alpha Company sells their product for $ 1 each. The variable costs are $ 7 per unit and the fixed costs are $ 30,000 per year. How much should we sell the unit to: 1- Reach the break-even point 2- Achieve a net profit of $ 21,000 3- Achieve a net profit equal to $ 21,000.
we have that
Part 1
Remember that breakpoint is when the revenue (R) is equal to the cost (C)
so
C=7x+30,000
R=10x
equate both equations
10x=7x+30,000
solve for x
10x-7x=30,000
3x=30,000
x=10,000 units
the answer Part 1 is 10,000 unitsPart 2
net profit of $ 21,000
so
R-C=21,000
10x-(7x+30,000)=21,000
10x-7x-30,000=21,000
3x=21,000+30,000
3x=51,000
x=17,000 unitsPart 3
net profit equal to $ 60,000
so
R-C=60,000
10x-(7x+30,000)=60,000
10x-7x-30,000=60,000
3x=60,000+30,000
3x=90,000

Write an inequality whose solution is the possible size of each of the 4barrels.c. How are these two problems similar? How are they different? Solve ach problem.
According to the statement given in Part a, there is one table for 10 people and many tables for 4 and in total there are tables for 200 people. Taking x as the number of tables for 4 people, the inequality that represents this situation is:
[tex]\begin{gathered} 4x+10\leq200 \\ 4x\leq190 \\ x\leq47.5 \end{gathered}[/tex]It means that there must be less than or 47.5 tables in the cafeteria.
According to the statement given in Part b, there are 4 barrels that are the same size, and one that is 10 liters, in total they can hold 200 liters. Taking x as the volume hold by the 4 barrels , the inequality that represents this situation is:
[tex]\begin{gathered} 4x+10\leq200 \\ 4x\leq190 \\ x\leq47.5 \end{gathered}[/tex]It means that each barrel must hold less than or 47.5 liters of water.
These problems are similar because of the inequality used to find the solution is the same, they are different because of the variable that is found is completely different, the first one is the number of tables and the second one is the volume that can be hold by the barrels.

28. Find four consecutive integers with the sum of 54.
The four consecutive integers with the sum of 54 is 12, 13, 14, 15
Let the four consecutive integers be x, x+1 , x+2, x + 3
x + x + 1 + x + 2 + x + 3 = 54
4x + 6 = 54
4x = 48
x = 12
The consecutive integers are
x = 12
x + 1 = 12 + 1 = 13
x + 2 = 12 + 2 = 14
x + 3 = 12 + 3 = 15
Therefore, the four consecutive integers with the sum of 54 is 12, 13, 14, 15

I have attached a picture of the graph below.
Please do not answer if you don't know or are not sure. Thank you.
Answer:
x = 8 for f(x) and x = 3 for h(x)
Step-by-step explanation:
the axis of symmetry is a vertical line which passes through the vertex of the graph with equation
x = c ( c is the value of the x- coordinate of the vertex )
the equation of a parabola in vertex form is
f(x) = a(x - h )² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = - 4(x - 8)² + 3 ← is in vertex form
with vertex (h, k ) = (8, 3 )
equation of axis of symmetry of f(x) is x = 8
given the graph of h(x) with vertex = (3, 2 ) , then
equation of axis of symmetry of h(x) is x = 3

Rational number will be 1/4, 2/3, √4 and Irrational number will be √8, √90, π/2, π as "Any whole number, fraction, or decimal that ends or repeats is a rational number. Any number that cannot be divided into a fraction and thus does not meet the definition of a rational number is considered to be irrational."
What is rational number?If p and q are integers and q is not equal to 0, then the number is in the form of p/q and is said to be rational. Among the rational number examples are 1/3, 2/4, 1/5, 9/3, and so forth. P/Q is the format for rational numbers, where p and q are open-ended integers and q 0. Thus, natural numbers, whole numbers, integers, fractions of integers, and decimals are all examples of rational numbers (terminating decimals and recurring decimals).
What is irrational number?Any real number that cannot be expressed as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number. For instance, the square root of 2 cannot be expressed as an integer or a fraction. A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational. Example: The numbers 2, 3, 5, 11, 21, and (Pi) are all illogical.
Here,
Rational number=1/4, 2/3, √4
Irrational number=√8, √90, π/2, π
As "Any whole number, fraction, or decimal that ends or repeats is a rational number. Any number that cannot be divided into a fraction and thus does not meet the definition of a rational number is considered to be irrational." so Rational number will be 1/4, 2/3, √4 and Irrational number will be √8, √90, π/2, π.
