Total number of students is 126
Part A: About ⅔ of the students chose to go to the arcade. Calculate the number of buses needed for the arcade trip if each bus can transport 42 students. Explain your step
Answer:
2 buses would be needed for the Arcade trip
Step-by-step explanation:
Step 1
Total number of students = 126
We find 2/3 of the total number of students
2/3 want to go to the Arcade.
Hence,
2/3 × 126 = 252/3
= 84 students.
84 students want to go to the Arcade
Step 2
We are told in the question that
1 bus can transport 42 students
Hence,
42 students = 1 bus
84 students = x bus
Cross Multiply
42 × x = 84 × 1
x = 84 /42
x = 2 buses.
Hence, 2 buses would be needed for the Arcade trip

-3
Step-by-step explanation:
4x+1=2x-5
Get x on one side by subtracting 2x
2x+1=-5
Get x alone by subtracting 1
2x=-6
Simplify by dividing by 2
X=-3
Answer: x=-3
Step-by-step explanation: Pic is Attached. Hope this helps.
Isolate the variable to one side of the equals sign by adding or subtracting. Consolidate the constants (like 1 or 5) to the other side of the equals sign.Get the x alone by dividing out the 2 from the x on both sides.If you have a coyote at your house what should you do if its trying to kill your animals at your ranch ???? plz help me out cause the coyote is in my ranch right now PLZZZZZZZ

The half-life of a certain radioactive substance is 45 days. There are 6.2 grams present initially. On what day
will there be less than 1 gram remaining? Day
Answer:
There will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days
Step-by-step explanation:
The given parameters are;
The half life of the radioactive substance = 45 days
The mass of the substance initially present = 6.2 grams
The expression for evaluating the half life is given as follows;
[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]
Where;
N(t) = The amount of the substance left after a given time period = 1 gram
N₀ = The initial amount of the radioactive substance = 6.2 grams
[tex]t_{1/2}[/tex] = The half life of the radioactive substance = 45 days
Substituting the values gives;
[tex]1 = 6.2 \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]
[tex]\dfrac{1}{6.2} = \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]
[tex]ln\left (\dfrac{1}{6.2} \right ) = {\dfrac{t}{45} \times ln \left (\dfrac{1}{2} \right )[/tex]
[tex]t = 45 \times \dfrac{ln\left (\dfrac{1}{6.2} \right ) }{ln \left (\dfrac{1}{2} \right )} \approx 118.45 \ days[/tex]
The time that it takes for the mass of the radioactive substance to remain 1 g ≈ 118.45 days
Therefore, there will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days.

Car A costs $25.95 to rent and $0.35/km to drive. Car B costs $19.95 to rent and $0.55/km to drive. Let y represent the total cost to rent a car and m represent the number of kilometers a person drives. If you are solving the equation, how many km would you have to drive for the total cost to be the same?
0.35m + 25.95= 0.55m + 19.95
1) 60 kilometers for them to be the same
2) 6 kilometers for them to be the same
3) 12 kilometers for them to be the same
4) 30 kilometers for them to be the same

A sales agent makes 40 calls a day. About 15% he calls result in a sale. How many days
will it take for the sales agent to meet a quota of 120 sales?
Answer: 20 days
Step-by-step explanation:
Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:
= 15% × 40
= 0.15 × 40
= 6
6 sales out of every 40 calls per day.
The number of calls to make 120 sales will be:
= 15% of x = 120
0.15 × x = 120
0.15x = 120
x = 120/0.15
x = 800 calls
Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:
= 800/40
= 20 days

Fred is 4 times as old as Nathan and is also 27 years older than Nathan. Let f be Fred's age and let n be Nathan's age.
Answer:
The system of equations is
and
Fred's age is 36 years old and Nathan's age is 9 years old
Step-by-step explanation:
Let
f -----> Fred's age
n ----> Nathan's age
we know that
-----> equation A
----> equation B
equate the equations and solve for n
Find the value of f
therefore
Fred's age is 36 years old and Nathan's age is 9 years old

How many candy bars must be sold to make a profit of $700?
Answer:800
Step-by-step explanation:
I'm assuming (P) represents profit
Apply out 700 in the equation
700=1.50n-500
Add 500 to each side
1200=1.50n
Divide each side by 1.50
800=n.
800 bars must be sold
800 candy bars must be sold to make a profit of $700.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, p = 1.50n - 500, assuming no. of candy bars to be n and we had a profit of $700.
∴ No. of candy bars sold to make a profit of $700 is,
700 = 1.50n - 500.
700 + 500 = 1.50n.
1.50n = 1200.
n = 1200/1.50.
n = 800 candy bars.
