A) $16
B) $20
C) $28
D) $40
Answer:
D) $40
Step-by-step explanation:
We need to find the DIFFERENCE between Susan's and Jim's lawn care business in the amounts they charge for 10 hours at work.
Solution:
First we will find the hourly charges of lawn care for both.
Given:
From the table of Jim we can see that
Charges of Jim for 1 hour = $20
So for 10 hour = Charges of Jim for 10 hour.
By using Unitary method we get;
Charges of Jim for 10 hour = [tex]10\times 20 =\$200[/tex]
Now From table of Susan we can see that;
for 2 hours = $48
So for 1 hour = Charges of Susan for 1 hour.
By Using Unitary method we get;
Charges of Susan for 1 hour = [tex]\frac{48}{2}= \$24[/tex]
Now we know that;
Charges of Susan for 1 hour = $24
So for 10 hour = Charges of Susan for 10 hour
again by using Unitary method we get;
Charges of Susan for 10 hour = [tex]24\times10 =\$240[/tex]
Now we need to find the difference between their charges.
Difference can be calculated by subtracting Charges of Jim for 10 hour from Charges of Susan for 10 hour.
framing in equation form we get;
Difference = [tex]\$240-\$200=\$40[/tex]
Hence The difference in the charges for 10 hour of work is $40.

Suppose x is directly proportional to y but inversely proportional to z. If x =3 when y = 6 and z =4, then what is z when y=3?
When y = 3, the value of z is 2.
Since x is directly proportional to y and inversely proportional to z, we can write this relationship as:
[tex]x = k \frac{y}{z}[/tex]
where k is a constant of proportionality.
We are given the values x = 3, y = 6, and z = 4. Let's use these values to find k.
[tex]3 = k \frac{6}{4}[/tex]
Simplifying this, we get:
[tex]3 = k \cdot 1.5[/tex]
Solving for k:
[tex]k = \frac{3}{1.5} = 2[/tex]
Now we know the constant k. We can use it to find z when y = 3.
We know the relationship:
[tex]x = 2 \frac{y}{z}[/tex]
We need to find z when x = 3 and y = 3.
[tex]3 = 2 \frac{3}{z}[/tex]
Rearranging to solve for z:
[tex]3 = 6 \div z[/tex]
[tex]z = 2[/tex]

The population of a small town is modeled by an exponential function of the form p t( ) = abt , where t represents the number of years since 2010. The population of the town was recorded as 425 in 2010 and 612 in 2012. Based on the data for the years 2010 and 2012, what is the value of b in the model?
To find the value of b in the exponential function, we can use the given data points for the years 2010 and 2012. By substituting the values into the equations, we can solve for b.
Explanation:To find the value of b in the exponential function, we can use the given data points for the years 2010 and 2012. Let's start by setting up two equations:
p(0) = ab0 = a = 425
p(2) = ab2 = 612
From the first equation, we know that a = 425. Substituting this value into the second equation:
425b2 = 612
Divide both sides of the equation by 425:
b2 = 612/425
Take the square root of both sides:
b = √(612/425)
Simplifying the expression gives us the value of b.

Thomas had 12 juice boxes he gave some to his sisters he now has more rhan 5 left.Which inequality can be used to find j the number of juice boxes thomas gave to his sisters?
Answer:
J < T - 5
Step-by-step explanation:
T = The number of juice boxes Thomas had
J = The number of juice boxes Thomas gave to his sisters
Thomas had 12 juice boxes
T = 12
He gave some to his sisters he now has more than 5 left.
T - J > 5
-J > 5 - T
J < -5 + T
J < T - 5
To determine the number of juice boxes Thomas gave to his sisters, the inequality 12 - j > 5 is used, which simplifies to j < 7, indicating that he gave away fewer than 7 juice boxes.
To find j, the number of juice boxes Thomas gave to his sisters, we start with the total number he had initially, which is 12. We know that he gave away some juice boxes and still has more than 5 left. If we let j represent the number of juice boxes given to his sisters, then 12 - j > 5 would be the inequality that can be used to determine j.
Since Thomas has more than 5 left, but we don't know the exact number, we use the inequality to represent the situation. Therefore, if we solve the inequality, subtracting 5 from both sides, we get j < 7. This means that Thomas gave away fewer than 7 juice boxes to his sisters because he had more than 5 remaining.

The first term is 1 in the geometric sequence 1, −3, 9, −27, . . . What is the SEVENTH term of the geometric sequence? Select your answer.
A. −243
B. −30
C. 81
D. 189
E. 729
Answer:
729
Step-by-step explanation:
The first term is 1 in the geometric sequence 1, −3, 9, −27, . .
First find out the nth term formula for the geometric sequence
[tex]a_n=a_1(r)^{n-1}[/tex]
where a_1 is the first term =1
r is the common ratio,
[tex]\frac{-3}{1}=-3[/tex]
[tex]\frac{9}{-3}=-3[/tex]
[tex]\frac{-27}{9}=-3[/tex]
r=-3, a_1=1
[tex]a_n=a_1(r)^{n-1}[/tex]
[tex]a_n=1(-3)^{n-1}[/tex]
Now find out the seventh term, n=7
[tex]a_7=1(-3)^{7-1}=729[/tex]
To find the seventh term of the geometric sequence 1, −3, 9, −27, ..., we calculate the common ratio and use it in the formula for the n-th term. The common ratio is −3 and the seventh term turns out to be 729. So the correct option is E.
Explanation:Calculating the SEVENTH Term of a Geometric Sequence
The given geometric sequence is 1, −3, 9, −27, ... and we are asked to find the seventh term. In a geometric sequence, each term after the first is found by multiplying the previous term by a constant called the common ratio (r). To find the common ratio, we can divide the second term by the first term, or the third term by the second term, and so on.
Common ratio (r) calculation:
Divide the second term (−3) by the first term (1), which gives us r = −3.
To find the seventh term, we use the formula for the n-th term of a geometric sequence, which is:
a_n = a_1 × r^(n-1), where a_n is the n-th term, a_1 is the first term, and n is the term number.
Seventh term calculation:
a_7 = 1 × (−3)^(7-1) = 1 × (−3)^6. Since −3 to an even power is positive, the answer is 1 × 3^6 = 729.
Therefore, the seventh term of the geometric sequence is 729.

A motorboat left a harbor and traveled to an island at an average rate of 10 knots. The average speed on the return trip was 10 knots. If the total trip took 4.0 hours, how far is the harbor from the island?
The distance between the harbor and the island is 20 nautical miles.
Explanation:To find the distance between the harbor and the island, we need to calculate the average speed of the motorboat for the entire trip. Since the average speed on the outbound trip was 10 knots and the average speed on the return trip was also 10 knots, we can conclude that the boat traveled at a constant speed throughout the trip. Let's assume the distance between the harbor and the island is 'd'.
Since speed = distance / time, we can calculate the time taken for each leg of the trip using the average speeds and the total time of 4.0 hours:
Time taken for the outbound trip = d / 10 knots
Time taken for the return trip = d / 10 knots
Since the total time is 4.0 hours, we can write the equation: d / 10 + d / 10 = 4.0
Simplifying the equation, we get: 2d / 10 = 4.0
Multiplying both sides by 10, we get: 2d = 40
Dividing both sides by 2, we get: d = 20
Therefore, the distance between the harbor and the island is 20 nautical miles.

The perimeter of a rectangle is 48 in the length of 6 in greater than the width Define a variable and write an equation to represent the situation solve the system by using substitution
Answer:
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of a rectangle is 48 in. It means that
48 = 2(L + W)
L + W = 48/2
L + W = 24 - - - - - - - - - 1
the length of the rectangle is 6 in greater than the width. It means that
L = W + 6
Substituting L = W + 6 into equation 1, it becomes
W + 6 + W = 24
2W + 6 = 24
2W = 24 - 6 = 18
W = 18/2 = 9
L = W + 6 = 9 + 6 = 15
Final answer:
The student's problem involves finding the length and width of a rectangle given its perimeter and the fact that the length is 6 inches greater than the width. To solve it, we defined the width as a variable, set up an equation based on the perimeter, and used substitution to find that the width is 9 inches and the length is 15 inches.
Explanation:
The perimeter of a rectangle is given by the formula 2(length + width). In the stated problem, we are given the total perimeter (48 inches) and told that the length is 6 inches greater than the width. We can define the width as w and the length as w + 6. So, the perimeter equation is:
2(w + (w + 6)) = 48
Simplify the equation: 2(2w + 6) = 48.Distribute the 2: 4w + 12 = 48.Subtract 12 from both sides: 4w = 36.Divide by 4 to find w: w = 9.Now that we have the width, we can find the length using substitution:
w + 6 = 9 + 6 = 15
Therefore, the width is 9 inches and the length is 15 inches.
A lone distance call costs 40 cents for the first three minutes and 10 cents for each additional minute. At most how many minutes can a person talk and not exceed $2?
Final answer:
A person can talk for at most 19 minutes on a long-distance call without exceeding a $2 limit, accounting for the initial charge and the cost of additional minutes.
Explanation:
To find out at most how many minutes a person can talk on a phone without exceeding $2, considering the initial charge is 40 cents for the first three minutes, and 10 cents for each additional minute, we need to calculate the total cost based on the number of minutes.
The problem can be broken down as follows:
The cost for the first 3 minutes is 40 cents.
After the initial 3 minutes, each additional minute costs 10 cents.
We have a budget of $2 (or 200 cents) to not exceed.
First, subtract the initial 40 cents from the total budget:
200 cents - 40 cents = 160 cents
With 160 cents left and each additional minute costing 10 cents:
160 cents[tex]\(\div\)[/tex] 10 cents = 16 additional minutes
Therefore, adding the initial 3 minutes:
3 + 16 = 19 minutes
A person can talk for at most 19 minutes without exceeding a $2 limit.

Company A charges $70.50 and 18 cents per mile. Company B charges $30.50 and 11 cents per mile. How much more does company A charge for x miles than company B?
Answer:
Step-by-step explanation:
Let x represent the number of miles with either company A or company B.
Company A charges $70.50 and 18 cents per mile. Converting 18 cents to dollars, it becomes
18/100 = $0.18
Total cost of x miles with company A would be
0.18x + 70.50
Company B charges $30.50 and 11 cents per mile. Converting 11 cents to dollars, it becomes
11/100 = $0.11
Total cost of x miles with company B would be
0.11x + 30.50
For the amount that company A charges more than company B, it becomes
0.18x + 70.50 - 0.11x + 30.50
0.18x - 0.11x + 70.5 - 30.5
0.07x + 40
Company A charges 0.07x + 40 more than company B
Grandma's Bakery sells single-crust apple pies for $6.99 and double-crust pies for $10.99. The total number of pies sold on Friday was 331.64. How many each type were sold?
Answer: the number of single-crust cherry pies that was sold is 16
the number of double-crust apple pies that was sold is 20
Step-by-step explanation:
Let x represent the number of single-crust cherry pies that was sold.
Let y represent the number of double-crust apple pies that was sold.
The total number of pies sold on a busy Friday was 36. This means that
x + y = 36
Grandma's Bakery sells single-crust apple pie for $6.99 and double-crust cherry pie for $10.99. If the amount collected for all the pies that day was $331.64, it means that
6.99x + 10.99y = 331.64 - - - - - - - - -1
Substituting x = 36 - y into equation 1, it becomes
6.99(36 - y) + 10.99y = 331.64
251.64 - 6.99y + 10.99y = 331.64
- 6.99y + 10.99y = 331.64 - 251.64
4y = 80
y = 80/4 = 20
x = 36 - y = x = 36 - 20
x = 16

The tax changed from 17.5% of the car's price to 20% of the car's price, an increase of 2.5% of the car's price.
The increased tax amount is ...
0.025 × £15000 = £375
The price of the car went up by £375 due to the increase in VAT.
A system of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. Can such a system have a unique solution? Explain.
Answer:
So such system with fewer equations than unknowns can never have a unique solution.
Step-by-step explanation:
Linear equations are equations which contain variable with degree 1.
The variables can be 1 or 2 or any other number
say there are n varaibles
Then to solve this we must have n independent equations.
If number of equations are less than number of variables we can have parametric solutions only with infinite points lying on it.
There is no chance for this to have a unique solution.
For unique solutions, there must be equal number of equations with the variables and the determinant formed by the coefficients should not be 0.
So such system with fewer equations than unknowns can never have a unique solution.
