The total remaining length of road that needs to be paved after the four days is: b). 1 5/6.
How to determine total remaining length of road that needs to be paved?In order to determine total remaining length of road that needs to be paved after the four days, we would evaluate and simplify the fraction for the expressions as follows;
Length of road paved in four days = 35/6 + 39/6 + 52/6 + 25/6
Length of road paved in four days = (35 + 39 + 52 + 25)/6
Length of road paved in four days = 151/6
Total length of road = 27 miles = 162/6 miles
Therefore, the total remaining length of road that should be paved after the four days can be calculated as follows;
total remaining length = 162/6 - 151/6
total remaining length = 11/6
total remaining length = 1 5/6 miles.

Find the amount of air needed to fill a basketball whose diameter is 9.45 in. Use 3.14 for
Answer:
The amount of air needed to fill the basketball is approximately 533.16 cubic inches
Step-by-step explanation:
To find the amount of air needed to fill a basketball, we need to first calculate its volume. We can use the formula for the volume of a sphere, which is V = (4/3)πr^3, where π is approximately 3.14 and r is the radius of the sphere.
Since the diameter of the basketball is given, we need to first find the radius by dividing the diameter by 2:
r = 9.45 in / 2 = 4.725 in
Now we can plug in the value of r into the formula for the volume:
V = (4/3)πr^3 = (4/3)π(4.725 in)^3 = 533.16 in^3
Therefore, the amount of air needed to fill the basketball is approximately 533.16 approx cubic inches.

The matrix equation below can be used to solve a system of when your equation what is the solution to the system? [6,4][x]=[1], [9,6][y]=[3]
There is no solution from the given matrix equation.
Solving two by two matrix equations.
In a two by two matrix equation system, two matrices can be multiplied if and only if the number of columns in the first matrix is equal to the number of rows in the second matrix. It implies that the first matrix is 2×2 and the second matrix is 2×1.
Given that:
[tex]\left[\begin{array}{cc}6&4\\9&6\end{array}\right] \left[\begin{array}{c}x\\y \end{array}\right] = \left[\begin{array}{c}1 \\ 3 \end{array}\right][/tex]
We multiply each row in the first matrix by each column in the second matrix, so we get:
[tex]\left[\begin{array}{c}6x+4y\\9x+6y\end{array}\right] = \left[\begin{array}{c}1 \\ 3 \end{array}\right][/tex]
Then, we can express it as a system of linear equations:
6x + 4y = 1 --- (1)
9x + 6y = 3 --- (2)
Here, we decided to use the substitution method to solve the system of equations.
From equation (1)
x = 1/6 - 2y/3
Replace the value of x into equation (2) and solve for y, we get:
9(1/6 - 2y/3) + 6y = 3
By solving it, we get:
3/2 = 3
Thus, since 3/2 = 3 is not a true solution, then we can conclude that there is no solution.

A population is growing according to the exponential model given by, P(t)=500^0.25t where t is measured in years. How many years will it take for the population to reach 1500? (Round your answer to one decimal place.)
It will take approximately 8.6 years for the population to reach 1500.
We have,
We are given that the population is growing exponentially according to the model, P(t) = 500^(0.25t),
where t is measured in years.
We need to find the value of t when the population reaches 1500.
So we can set P(t) = 1500 and solve for t:
1500 = 500^(0.25t)
Taking the natural logarithm of both sides:
ln(1500) = ln(500^(0.25t))
Using the logarithmic identity, ln(a^b) = b ln(a):
ln(1500) = 0.25t ln(500)
Solving for t:
t = ln(1500) / (0.25 ln(500))
Using a calculator, we get:
t ≈ 8.6 years
Therefore,
It will take approximately 8.6 years for the population to reach 1500.

You're welcome.Carter was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 31%. What number should he multiply the cost of the meal by to find the total plus tip in one step?
The total cost of the meal is $65.50, with tip included.
Here, in this question we need to find the percentage Value, to find the total cost of the meal plus the tip, Carter needs to multiply the cost of the meal by a factor of 1 + the tip percentage, which is 1 + 31% = 1.31.
So, the number Carter should multiply the cost of the meal by to find the total plus tip in one step is 1.31.
For example, if the cost of the meal was $50, then the total cost including the tip would be addition of cost of meal and tip.
Total cost = Cost of meal + Tip
Total cost = $50 + 31% of $50
Total cost = $50 + $15.50

Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0
The equations that are true for x = -2 and x = 2 are x² + 4 = 0 and 4x² = 16. So, the correct option is A) and D).
To determine which equations are true for x = -2 and x = 2, we simply substitute these values into each equation and check if the equation is true or not. Here are the results
x² - 4 = 0
Substituting x = -2 gives (-2)² - 4 = 0, which is true. Substituting x = 2 gives 2² - 4 = 0, which is also true. Therefore, this equation is true for both x = -2 and x = 2.
x² = -4
Substituting x = -2 gives (-2)² = -4, which is not true. Substituting x = 2 gives 2² = -4, which is also not true. Therefore, this equation is not true for either x = -2 or x = 2.
3x² + 12 = 0
Substituting x = -2 gives 3(-2)² + 12 = 0, which is true. Substituting x = 2 gives 3(2)² + 12 = 24, which is not equal to zero. Therefore, this equation is true for x = -2 but not for x = 2.
4x² = 16
Substituting x = -2 gives 4(-2)² = 16, which is true. Substituting x = 2 gives 4(2)² = 16, which is also true. Therefore, this equation is true for both x = -2 and x = 2.
2(x - 2)² = 0
Substituting x = -2 gives 2(-2 - 2)² = 0, which is true. Substituting x = 2 gives 2(2 - 2)² = 0, which is also true. Therefore, this equation is true for both x = -2 and x = 2.
Therefore, the two equations that are true for both x = -2 and x = 2 are x² - 4 = 0 and 4x² = 16. So, the correct answer is A) and D).

The solution of the expression is 3.659
First, we will start with the expression inside the brackets, i.e., [(3 1/3 * 1.9) + (19.5 / (4 1/2)]. Here, we have two operations - multiplication and division. According to PEMDAS, we need to perform multiplication before division.
To simplify this expression, we will first convert 3 1/3 to an improper fraction. 3 1/3 is the same as 10/3. Therefore, the expression inside the brackets becomes
=> [(10/3 * 1.9) + (19.5 / (9/2)].
Next, we will simplify the multiplication first -
=> 10/3 * 1.9 = 19/3.
Now, let's simplify the division operation
=> 19.5 / (9/2) = 4.33
Therefore, the expression inside the brackets becomes
=> [(19/3) + 4.33] = 8.99
Moving on to the denominator of the given expression
=> [62/75 - 0.16]. Here, we need to perform subtraction first as it comes before division in PEMDAS.
62/75 = 0.8266
Therefore, the denominator of the given expression becomes
=> [0.8266 - 0.16] = 0.6666
Now, let's simplify the numerator of the given expression. We have
=> [(3.5 + 4 2/3 + 2 2/15) / (0.5 * (1 1/20 + 4.1))].
Let's first convert all the mixed fractions to improper fractions.
3.5 can be written as 7/2, 4 2/3 can be written as 14/3, and 2 2/15 can be written as 32/15.
Therefore, the numerator becomes
=> [(7/2 + 14/3 + 32/15) / (0.5 * (21/20 + 4.1))].
Let's first simplify the expression inside the brackets
=> 21/20 + 4.1 = 5.15.
Therefore, the numerator becomes
=> [(7/2 + 14/3 + 32/15) / (0.5 * 5.15)].
Now, let's simplify the addition operation in the numerator. We need to find a common denominator to add the fractions.
The common denominator for 2, 3, and 15 is 30.
Therefore, (7/2 + 14/3 + 32/15) can be written as
=> (105/30 + 140/30 + 64/30).
Adding the fractions, we get (309/30).
Therefore, the numerator becomes [(309// (0.5 * 5.15)].
Next, let's simplify the expression inside the brackets - 0.5 * 5.15 = 2.575.
Therefore, the numerator becomes
[(309/30) / 2.575] = 3.68
Now that we have simplified the numerator and denominator of the given expression separately, we can simplify the entire expression.
[(8.99) / (0.6666)] / [3.68]
Let's first simplify the expression inside the first set of brackets.
(8.99) / (0.6666) = 13.486
Therefore, the given expression becomes 13.486 / 3.68 = 3.659

There are 24 ways to pick two green marbles first and one red marble last.
The probability of picking a green marble on the first draw is 4/10, and then 3/9 on the second draw since there are only 3 green marbles left out of 9 total marbles remaining.
The probability of picking a red marble on the third draw is 4/8 since there are 4 red marbles left out of 8 total marbles remaining.
So the probability of picking two green marbles first and one red marble last is (4/10) x (3/9) x (4/8) = 2/45.
To calculate the number of ways to pick two green marbles first and one red marble last, we need to use combinations.

The capacity of a water tank is 1000 gallons. Don uses a bucket that can hold 2 gallons to fill the tank. It takes him 3 minutes to fill the bucket with water and pour it into the tank.
Don would take 1500 minutes to fill the 1000-gallon water tank using the 2-gallon bucket.
If the capacity of the water tank is 1000 gallons and Don uses a bucket that can hold 2 gallons to fill the tank, we can calculate the number of buckets Don needs to fill the tank.
Let's assume the number of buckets Don needs to fill the tank is represented by 'n'.
Capacity of the tank = 1000 gallons
Capacity of each bucket = 2 gallons
Number of buckets needed to fill the tank, n = Capacity of the tank / Capacity of each bucket
n = 1000 gallons / 2 gallons
n = 500
So, Don needs 500 buckets, each holding 2 gallons, to fill the 1000-gallon water tank.
Given that it takes Don 3 minutes to fill the bucket with water and pour it into the tank, the total time taken by Don to fill the tank would be the product of the number of buckets (500) and the time taken to fill each bucket (3 minutes).
Total time taken to fill the tank = Number of buckets × Time taken to fill each bucket

where
L=The lower limit of the median group
n = The total number of observations
F = The cumulative frequency up to the median group
f =The frequency of the median group
w = The width of the median group
median = 5 + ( ( 14/2 - 4 ) /9 × 4
= 6.33
Therefore, from the histogram the number of students exercised for ,
4 hours or more are 14.
9 hours or fewer are 13.

find the domain range and function
The domain of this relation is [0, 5].
The range of this relation is [-4, 3].
No, this relation is not a function.
What is a domain?In Mathematics and Geometry, a domain refers to the set of all real numbers (x-values) for which a particular function (equation) is defined.
How to identify the domain any graph?In Mathematics and Geometry, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.
By critically observing the graphs shown in the image attached above, we can reasonably and logically deduce the following domain and range for graph 4:
Domain = [0, 5].
Range = [-4, 3].

write the equation of a function whose parent function, f(x)= x+6, is shifted 4 units to the right
The transformed fuction shifted 4 units to the right of the parent function is g(x)= x + 2
Writing the equation of the transformed functionFrom the question, we have the following parameters that can be used in our computation:
Parent function, f(x)= x+6,
Transformation: shifted 4 units to the right
The rule of the above transformation is
g(x) = f(x - 4)
Substitute the known values in the above equation, so, we have the following representation
g(x)= x - 4 + 6,
Evaluate the terms
g(x)= x + 2
Hence, the transformed fuction is g(x)= x + 2

Match each logarithmic equation to its corresponding x-value.
The logarithm equations and corresponding x-value are
[tex]log_{2}x=5[/tex] has x=32
[tex]log_{10}x=3[/tex] then x=1000
[tex]log_{4}x=2[/tex] then x=16
[tex]log_{3}x=1[/tex] then x=1
We know that [tex]log_{a}x=b[/tex]
Then [tex]x=a^b[/tex]
(1) [tex]log_{2}x=5[/tex]
x=2⁵
=32
So [tex]log_{2}x=5[/tex] has x=32
(2) [tex]log_{10}x=3[/tex]
Then by using the above property of logarithmic function we have:
x=10³
x=1000
So [tex]log_{10}x=3[/tex] then x=1000
(3) [tex]log_{4}x=2[/tex]
x=4²
x=16
so [tex]log_{4}x=2[/tex] then x=16
(4) [tex]log_{3}x=1[/tex]

The missing sides of the right triangle were obtained below.
What is the Pythagoras theorem?Pythagoras' theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
We have that;
1) x = √26^2 - 10^2
x = 24
2) x = √20^2 + 14 ^2
x = 24.4
3) x = √50^2 - 30^2
x = 40
4) x = √15^2 + 5^2
x = 15.8
5) x = √12^2 + 20^2
x = 23.3
These are the sides that are missing.
