a washer and a dryer cost $809 combined. the washer costs $91 less than the dryer. what is the cost of the dryer?
Answer:
The Dryer cost is 450
Step-by-step explanation:
The washer cost $450. and together they have the cost is 787.
A washer and a dryer cost $809 combined.
Let the dryer cost x.
Then, the washer costs (x-91)
Together, they cost (x) + (x-91) =809
2x+91 = 809
We have to solve this equation
What is the equation?An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
2x = 718 ....... [subtract 97 from both sides]
x = 359 ....... [divide both sides by 2]
The dryer cost $359.
Therefore, the washer cost $450.
Together, they cost,
450+359=$787
The washer cost $450. and together they have the cost is 787.

Answer:
c = 11.3 yards
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 416.955, h = 20.9, a = 28.6 and b = c, thus
[tex]\frac{1}{2}[/tex] × 20.9 × (28.6 + c) = 416.955, that is
10.45(28.6 + c) = 416.955 ( divide both sides by 10.45 )
28.6 + c = 39.9 ( subtract 28.6 from both sides )
c = 11.3 yards

Luther is building a model rocket for a science fair project. He attaches a nose cone to a cylindrical body to
form the rocket's fuselage. The rocket has a diameter of 4 inches and a total height (including the nosecone)
of 19 inches. The nosccone is 7 inches tall. What is the surface area of the rocket?
The total approximate surface area of Luther's rocket is 219.8 square inches.
Luther is building a model rocket and needs to calculate its surface area. His rocket consists of a cylindrical body with a nose cone. The diameter of the cylinder is 4 inches, the height of the cylindrical part is 12 inches (since the total height is 19 inches and the nose cone is 7 inches), and the height of the nose cone is 7 inches.
First, we calculate the surface area of the cylindrical body. The formula for the lateral surface area of a cylinder is 2πr*h, where r is the radius and h is the height. Half the diameter gives us the radius, which is 2 inches. Thus, the lateral surface area is 2π*2*12 = 48π square inches.
Next, we find the surface area of the two bases of the cylinder. The formula for the area of a circle is π[tex]r^2[/tex]. So, the area of one base is π*[tex]2^2[/tex] = 4π square inches. There are two bases, so we double this to get 8π square inches.
For the nose cone, we'll assume it is a cone whose slant height is the same as its height (because we do not have enough information to calculate the slant height if it were to differ). The surface area of a cone is πr*l, where l is the slant/linear height. Therefore, for the nose cone, we have π*2*7 = 14π square inches.
Now, we add the surface areas of the cylindrical part and the nose cone to get the total surface area of the rocket: 48π + 8π + 14π = 70π square inches.
Finally, multiplying 70π by approximately 3.14, we get the total approximate surface area of Luther's rocket: 70 * 3.14 = 219.8 square inches.
The correct answer is:
The surface area of the rocket is approximately [tex]\(48\pi + 2\pi(2 + \sqrt{53})\)[/tex] square inches, without numerical calculation.
To find the surface area of the rocket, we need to calculate the surface area of both the cylindrical body and the nose cone separately, then add them together.
1. Surface Area of the Cylindrical Body:
The cylindrical body's surface area can be calculated using the formula for the lateral surface area of a cylinder: [tex]\( A_{\text{cylinder}} = 2\pi rh \)[/tex], where [tex]\( r \)[/tex] is the radius and [tex]\( h \)[/tex] is the height.
Given:
- Diameter = 4 inches (radius = 2 inches)
- Total height (including nose cone) = 19 inches
- Height of the nose cone = 7 inches
Radius r = 2 inches
Height of cylindrical body = Total height - Height of nose cone = 19 inches - 7 inches = 12 inches
[tex]\( A_{\text{cylinder}} = 2\pi \times 2 \times 12 = 48\pi \)[/tex] square inches
2. Surface Area of the Nose Cone:
The surface area of a cone can be calculated using the formula: [tex]\( A_{\text{nosecone}} = \pi r_{\text{nosecone}}(r_{\text{nosecone}} + \sqrt{h_{\text{nosecone}}^2 + r_{\text{nosecone}}^2}) \), where \( r_{\text{nosecone}} \) is the radius and \( h_{\text{nosecone}} \)[/tex] is the height.
Given:
- Height of nose cone = 7 inches
Since the diameter of the rocket is 4 inches, the radius of the nose cone is also [tex]\( \frac{4}{2} = 2 \)[/tex] inches.
[tex]\( A_{\text{nosecone}} = \pi \times 2 \times (2 + \sqrt{7^2 + 2^2}) = 2\pi(2 + \sqrt{53}) \)[/tex] square inches
3. Total Surface Area:
The total surface area of the rocket is the sum of the surface areas of the cylindrical body and the nose cone.
Total Surface Area = Surface Area of Cylindrical Body + Surface Area of Nose Cone
[tex]\( = 48\pi + 2\pi(2 + \sqrt{53}) \)[/tex] square inches

Factor (x^2 – 9) (x^2 – 5x + 4) completely.
Answer:
I believe the answer is (x+3)(x-3)(x-4)(x-1)
Step-by-step explanation:
Notice both terms are perfect squares, therefore you can factor using the difference of squares formula:
(x²-9)(x²-5x+4)
For the first term, we get (x+3)(x-3) because x²-9 is a perfect square.
For the second term, we get (x-4)(x-1) because x²-5x+4 is a perfect square trinomial.

Two containers designed to hold water are side by side, both in the shape of a
cylinder. Container A has a radius of 7 feet and a height of 11 feet. Container B has a
radius of 6 feet and a height of 16 feet. Container A is full of water and the water is
pumped into Container B until Container A is empty.
After the pumping is complete, what is the volume of water in Container B, to the
nearest tenth of a cubic foot?
please help!!
Answer:
1693.3 ft³
Step-by-step explanation:
The volume of a cylinder is given by; V = πr²h
For container A;
we are given;
Radius;r = 7ft
Height; h = 11 ft
Thus; Volume of container A = π•(7²)•11 = 1693.318 ft³
Similarly,
For container A;
we are given;
Radius;r = 6 ft
Height; h = 16 ft
Thus; Volume of container B = π•(6²)•16 = 1809.557 ft³
Now, since container A was full of water and all of it was pumped into container B, thus, the volume of the water in container B = Volume of container A = 1693.318 ft³
Approximating to the nearest tenth of cubic ft = 1693.3 ft³

A company usually sends 9 people to install a security system in an office building, and they do it in about 96 minutes. Today, they have only three people to do the same size job. How much time should be scheduled to complete the job?
Answer:
The Answer would be 288 minutes
Step-by-step explanation:
So we have 9 people working to install a security system in an office building. they take about 96 minutes.
Today we have 3 people doing the same job.
yesterday we had 9 people doing the same job
so we would multiply 96 minutes by 3 because we divided the amount of people by 3
96x3= 288
3 people takes 288 minutes to do the same job.
To complete the installation of a security system that normally takes 9 people 96 minutes, three people would require 288 minutes given each person works at the same rate and the work is additive.
Explanation:When a company usually sends 9 people to install a security system in 96 minutes, and today only has three people available for the same task, we need to calculate the expected time for completion. First, we assume that each person works at the same rate. With 9 people, it takes 96 minutes, so with one person, it would take 9 times longer, since the number of workers is inversely proportional to the time needed.
So, one person would take 9 × 96 = 864 minutes to do the job alone. Therefore, three people would take 864 ÷ 3 = 288 minutes to complete the installation of the security system.
This calculation is based on the assumption that the work done by each individual is additive and that they are working on the task continuously and independently without interruption.
