The local toy store has a bin of toy vehicles for sale. The bin holds b bikes and c cars. If the store sells 1/3 of the vehicles in the bin, which expression represents the number of vehicles remaining in the bin?
The expression that can be used to represents the number of vehicles remaining in the bin is (b + c) - 1/3(b + c)
How to write a mathematical expression?Number of bikes = bNumber of cars = cTotal vehicles = b + c
Number of vehicles sold = 1/3 of total vehicles
= 1/3(b + c)
Number of vehicles remaining = (b + c) - 1/3(b + c)

The expression that represents the number of vehicles remaining in the bin is 2/3 (b + c).
To determine the number of vehicles remaining in the bin after selling 1/3 of them, we start by calculating the total number of vehicles initially present. This total number is represented by b + c, where b is the number of bikes and c is the number of cars.
If the store sells 1/3 of the vehicles, the number sold can be represented as:
(b + c) / 3
The number of vehicles remaining in the bin would be the original total minus the number sold:
(b + c) - (b + c) / 3
We can simplify this expression by finding a common denominator:
(b + c) - (b + c) / 3 = 3(b + c)/3 - (b + c) / 3 = (3(b + c) - (b + c)) / 3 = (2(b + c)) / 3
Therefore, the expression that represents the number of vehicles remaining in the bin is 2/3 (b + c).

a square reflecting pool has an area of 183.84 square meters. What is the approximate perimeter of the reflecting pool?
The perimeter of a square reflecting pool with an area of 183.84 square meters is approximately 54.24 meters.
Explanation:The area of a square is calculated by squaring the length of one of its sides. So, to find the side length of the square reflecting pool, we need to take the square root of the area. The square root of 183.84 is approximately 13.56 meters.
Now considering that a square has four equal sides, the perimeter is calculated by multiplying the side length by 4. So, the perimeter of the pool is 13.56 multiplied by 4, which gives us approximately 54.24 meters. Therefore, the approximate perimeter of the reflecting pool is 54.24 meters.

Suppose a railroad rail is 3 kilometers and it expands on a hot day by 12 centimeters in length. Approximately how many meters would the center of the rail rise above the ground
The center of the rail would rise approximately 0.06 meters above the ground.
The expansion of the railroad rail is given as 12 centimeters. To convert centimeters to meters, you divide by 100 since there are 100 centimeters in a meter.
So, the expansion in meters is 12/100 meters.
Now, the center of the rail would rise approximately half of this expansion because the rail expands equally on both sides. Therefore, the rise in the center of the rail above the ground would be
=1/2 × 12/ 100.
Let's calculate that:
Rise in the center= 1/2 × 12/100
Rise in the center=6/100
Now, to express this fraction in decimal form, you divide the numerator by the denominator:
Rise in the center= 0.06
So, the center of the rail would rise approximately 0.06 meters above the ground.

What is the total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months
The total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months can be calculated using the formula: Total Finance Charge = Total Amount Repaid - Principal Amount.
Explanation:The total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months can be calculated using the formula:
Total Finance Charge = Total Amount Repaid - Principal Amount
First, calculate the total amount repaid:
Convert the annual interest rate to the monthly interest rate by dividing it by 12: 13.25% / 12 = 1.1042%Convert the loan term from months to years: 24 months / 12 = 2 yearsCalculate the total amount repaid using the formula: Total Amount Repaid = Principal Amount + InterestNow, calculate the principal amount:
Principal Amount = Loan Amount = $4,250
Finally, substitute the values into the formula and calculate the total finance charge:
Total Finance Charge = Total Amount Repaid - Principal Amount

Which graph below shows a system of equations with infinitely many solutions?
A)coordinate plane with two parallel lines
B)coordinate plane with two intersecting lines
C)coordinate plane with two coinciding lines
D)coordinate plane with two intersecting lines
Answer: C)coordinate plane with two coinciding lines has infinitely many solution.
Step-by-step explanation:
Since, By option A) If there is a coordinate plane with two parallel lines.
Then, It has no solution ( because, we get the solution at the the intersection point of the two lines but parallel lines do not intersect each other).So, it does not have infinite many solution.
By Option B) If there are two intersecting lines then we can get only one solution. So, it does not have infinite many solution.
By Option C) If there are two coinciding lines then we can get infinite number of intersection points therefore the system must have infinite number of solution.
Note: here, Option D) is same as Option B)
Therefore Only option C) is correct.
In the time a person on a bicycle travels 4 miles a person in a car travels 30 miles assuming a constant speed how far will the car travel while the bicycle travels 40 miles
The car will travel 300 miles while the bicycle travels 40 miles
Explanation:Let's first calculate the ratio of distances traveled by the bicycle and the car in the given scenario:
Ratio of distances = Distance traveled by car / Distance traveled by bicycle
Ratio of distances = 30 miles / 4 miles = 7.5
This ratio represents the speed ratio between the car and the bicycle. Now, we can use this ratio to find the distance the car will travel while the bicycle travels 40 miles:
Distance traveled by car = Ratio of distances * Distance traveled by bicycle
Distance traveled by car = 7.5 * 40 miles = 300 miles

7.88 units is the distance between points T(13, 1.6) and V(5.4, 3.7).
To find the distance between the points T(13, 1.6) and V(5.4, 3.7), we can use the distance formula:
Distance formula:
For two points [tex](x_1, y_1)[/tex]and [tex](x_2, y_2)[/tex], the distance between them is [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.[/tex]
Let's plug in the coordinates of points T and V:
Distance = [tex]\sqrt{(5.4 - 13)^2 + (3.7 - 1.6)^2}[/tex]
= [tex]\sqrt{(-7.6)^2 + (2.1)^2}[/tex]
= √(57.76 + 4.41)
= √62.17
= 7.88.

Part 2. 2,6,18,54,162.. Step 1. State whether this sequence is arithmetic or geometric and find the explicit formula. show your work. Step 2.find the recursive formula. Show your work
Final answer:
The first sequence is arithmetic with an explicit formula of a_n = 10 + (n - 1) × 5 and recursive formula a_n = a_(n-1) + 5, a_1 = 10. The second sequence is geometric with an explicit formula of a_n = 2 × 3^(n-1) and recursive formula a_n = a_(n-1) × 3, a_1 = 2.
Explanation:
Analysis of Sequences
The first sequence: 10, 15, 20, 25, 30... increases by a constant amount of 5 which is an indication of an arithmetic sequence. The explicit formula for an arithmetic sequence is a_n = a_1 + (n - 1)d, where a_1 is the first term and d is the common difference between the terms. In this case, a_1 = 10 and d = 5. Hence, the explicit formula is a_n = 10 + (n - 1) × 5. The recursive formula for an arithmetic sequence is a_n = a_(n-1) + d, which would translate to a_n = a_(n-1) + 5 with a_1 = 10.
The second sequence: 2, 6, 18, 54, 162... multiplies by a common ratio of 3 which classifies it as a geometric sequence. The explicit formula for a geometric sequence is a_n = a_1 × r^(n-1), where a_1 is the first term and r is the common ratio. For this sequence, a_1 = 2 and r = 3, so the explicit formula is a_n = 2 × 3^(n-1). The recursive formula for a geometric sequence is a_n = a_(n-1) × r, which for this sequence is a_n = a_(n-1) × 3 with a_1 = 2.

A 12 foot ladder is placed 4 feet away from a house as shown. What is the value of x, rounded to the nearest degree ?
Answer: The value of x is 70.52°.
Step-by-step explanation:
Since we have given that
Length of ladder = 12 foot
Length of base = 4 feet
We need to find the value of 'x'.
We will use "Cosine of triangle":
[tex]\cos x=\dfrac{4}{12}\\\\x=\cos^{-1}(\dfrac{1}{3})\\\\x=70.52^\circ[/tex]
Hence, the value of x is 70.52°.

f(x)=(x^3+6) inverse
The inverse of this function is f(x) = [tex] \sqrt[3]{x - 6} [/tex]
You can find the value of any inverse function by switching the f(x) and the x value. Then you can solve for the new f(x) value. The end result will be your new inverse function. The step-by-step process is below.
f(x) = x^3 + 6 ----> Switch f(x) and x
x = f(x)^3 + 6 ----> Subtract 6 from both sides
x - 6 = f(x)^3 ----> Take the cube root of both sides
[tex] \sqrt[3]{x - 6} [/tex] = f(x) ----> Switch the order for formatting purposes
f(x) = [tex] \sqrt[3]{x - 6} [/tex]
And that would be your new inverse function.
