A 2-gallon container of laundry detergent costs $27.76. What is the price per quart?
The price of the cost per quart of laundry detergent is A = $ 3.47
Given data ,
Let the unit cost rate be A
Now , There are 4 quarts in a gallon, so a 2-gallon container contains 8 quarts.
To find the price per quart, we can divide the total cost by the number of quarts:
Price per quart = Total cost / Number of quarts
Price per quart = $27.76 / 8 = $3.47
Hence , the price per quart of laundry detergent is $ 3.47

A formula for calculating A, the area of trapezoid, is A = 1/2 h ( b + b ), where h is height of the trapezoid, and b1 and b2 are the lengths of the parallel sides. What is A when h=4 centimeters, b1 = 10 centimeters, and b2 = 5 centimeters ? A. 35 cm 2 B. 30 cm 2 C. 25 cm 2 D. 45 cm 2 ?
The area of the trapezium is 30 square centimeters at the values of h = 4 cm, b = 10 cm, and b' = 5 cm.
We can use the formula for the area of a trapezoid:
A = 1/2 * h * (b + b')
Substituting the given values, we get:
A = 1/2 * 4 cm * (10 cm + 5 cm)
Simplifying the expression inside the parentheses:
A = 1/2 * 4 cm * 15 cm
Multiplying:
A = 30 cm²
Therefore, when h = 4 cm, b = 10 cm, and b' = 5 cm, the area of the trapezoid is 30 square centimeters.

Use the given zero to find the remaining zeros of the function.
h(x)=3x^4+10x³+19x^2+90x-72; zero: -3i
The remaining zeros of h are ___
(Use a comma to separate answers as needed. Use integers or fractions for any numbers in the expression.)
Answer:
Since the coefficients of the polynomial function h(x) have real values, if -3i is a zero of h(x), then its complex conjugate 3i must also be a zero of h(x). This is known as the Complex Conjugate Root Theorem.
Therefore, the remaining zeros of h(x) can be found by dividing the polynomial by the factors (x - (-3i)) and (x - 3i), using either polynomial long division or synthetic division. Here, we'll use synthetic division:
3i | 3 10 19 90 -72
| 9i -63 -216 -294
+-----------------------
3 10+9i -44 -126 -366
Step-by-step explanation:
The quotient is 3x^3 + (10+9i)x^2 - 44x - 126, and the remainder is -366. This tells us that:
h(x) = (x - (-3i))(x - 3i)(3x^3 + (10+9i)x^2 - 44x - 126)
The remaining zeros of h(x) can now be found by solving the cubic polynomial 3x^3 + (10+9i)x^2 - 44x - 126. This can be done using various methods such as the Rational Root Theorem, factoring by grouping, or numerical methods. However, these methods can be quite involved and may not always lead to exact answers.

A monument outside city hall has dimensions as shown in the figure below. If one gallon of paint can cover 140 ft ^2, how many gallons of paint must be bought in order to paint the monument? Assume that the base of the monument cannot be painted and that paint can be bought only by the gallon.
The monument has a surface area of 432 square feet to be painted. Dividing this area by the coverage of one gallon of paint, we get a requirement of 4 gallons of paint to paint the monument.
As per the given figure, the monument has a rectangular shape with dimensions of length 12 feet, width 6 feet and height 18 feet.
The area of the monument that needs to be painted can be calculated by subtracting the area of the base that is not to be painted from the total surface area of the monument.
The area of the base that is not to be painted is 12 feet x 6 feet = 72 square feet.
The total surface area of the monument that needs to be painted is:
2 (length x height) + 2 (width x height) - area of base
= [tex]2 (12 ft x 18 ft) + 2 (6 ft x 18 ft) - 72 ft^2[/tex]
= [tex]432 ft^2[/tex]
Now, we can divide the total surface area of the monument by the area that can be covered by one gallon of paint:
[tex]432 ft^2 / 140 ft^2/gallon = 3.0857 gallons[/tex]
Since we can buy paint only by the gallon, we must round up to the nearest gallon. Therefore, we need to buy 4 gallons of paint to paint the monument.

stack height
in cm
The table shows the height of a stack of books based on the number of copies. Each copy of the book is 2.1 cm thick. Adding a new copy of the book increases the height of the stack by 2.1 cm, and the height increases by a factor of 1 for each new copy.
To complete the table, we need to find the stack height for each number of copies of the book. Since each copy of the book is 2.1 cm thick, we can use multiplication to find the total height of the stack for each number of copies
For 0 copies, the stack height is 0 cm.
For 1 copy, the stack height is 2.1 cm.
For 2 copies, the stack height is 4.2 cm (2.1 cm x 2).
For 3 copies, the stack height is 6.3 cm (2.1 cm x 3).
For 4 copies, the stack height is 8.4 cm (2.1 cm x 4).
Therefore, the completed table looks like
copies of book | 0 | 1 | 2 | 3 | 4
stack height | 0 | 2.1 | 4.2 | 6.3 | 8.4
Looking at the table, we can see that each time a new copy of the book is added, the height of the stack increases by 2.1 cm.
We can also observe that the factor by which the height of the stack changes when a new copy is added is always 1. This is because each copy of the book is the same thickness, so adding one copy always adds the same amount of height to the stack.

Watermelons needed to be loaded up from the farm to go to the local market.
The mass of the load on the truck is 56 kilograms. If the mass of each watermelon is 7 kilograms, how many watermelons are on this load?
Show your work.
If the mass of each watermelon is 7 kilograms, there are 8 watermelons on the load.
To find the number of watermelons on the load, we need to divide the total mass of the load by the mass of each watermelon. We can set up an equation to represent this:
Number of watermelons = Total mass of load / Mass of each watermelon
Plugging in the given values, we get:
Number of watermelons = 56 kg / 7 kg per watermelon
Simplifying, we get:
Number of watermelons = 8
Therefore, there are 8 watermelons on the load.
It's important to note that this calculation assumes that all the watermelons have the same mass of 7 kg. In reality, there may be some variation in the mass of the individual watermelons, which could affect the total number of watermelons on the load. Additionally, other factors such as the size and shape of the watermelons may also affect how many can fit on the truck.

The perimeter of parallelogram ABCD is cm. AD is cm more than twice AB. Find the lengths of all four sides of ABCD.
So the lengths of all four sides of ABCD are:
AB = BC = 15 cm
CD = DA = 31 cm
Let AB = x. Then AD = 2x + 1, since AD is 1 cm more than twice AB.
Since ABCD is a parallelogram, opposite sides are equal in length. So, BC = AB = x, and DC = AD = 2x + 1.
The perimeter of the parallelogram is the sum of the lengths of all four sides:
AB + BC + CD + DA = x + x + (2x + 1) + (2x + 1) = 6x + 2
We are given that the perimeter is 92 cm, so we can set this expression equal to 92 and solve for x:

4 |3x + 5| ≤ 16
The solution to the inequality is -3 ≤ x ≤ -1/3
Solving inequality with modulusGiven the inequality:
4|3x+5| ≤ 16
Let us simplify it by dividing both sides by 4 to get:
|3x+5| ≤ 4
Next, we can break the inequality into two cases, depending on whether 3x+5 is positive or negative:
First: 3x+5 ≥ 0
In this case, the inequality simplifies to:
3x+5 ≤ 4
Subtracting 5 from both sides, we get:
3x ≤ -1
Dividing by 3 (which is positive) gives:
x ≤ -1/3
Second: 3x+5 < 0
In this case, the inequality simplifies to:
-3x-5 ≤ 4
Adding 5 to both sides, we get:
-3x ≤ 9
Dividing by -3 (which is negative and requires us to flip the inequality), gives:
x ≥ -3
