Mr. Fry is building a fence around his pool. •Length of the fence is 60 feet. •Width of the fence is 30 feet. How many yards of fence will Mr. Fry build? A) 30 yards B) 60 yards C) 90 yards D) 540 yards i need help!!!!!!!!!
Answers
Mr. Fry will need 60 yards of fencing to encircle his pool, as the perimeter of the rectangular pool area is 180 feet and there are 3 feet in a yard.
To determine the total amount of fencing Mr. Fry will need, we calculate the perimeter of the rectangular area around the pool. The perimeter can be found by doubling the length then adding this to double the width. Therefore:
Perimeter = 2× Length + 2× Wid
= 2 × 60 feet + 2 × 30 feet
= 120 feet + 60 feet
= 180 feet
Now, knowing that 1 yard equals 3 feet, we can convert feet into yards:
Yards = Feet ÷ 3
= 180 feet ÷ 3
= 60 yards
Hence, Mr. Fry will need 60 yards of fence for his pool.
To determine the number of yards of fence Mr. Fry will build, we calculate the perimeter of the rectangular area (2 x (60 + 30) feet = 180 feet) and then convert it to yards (180 feet / 3 = 60 yards).
Mr. Fry is building a fence around his pool and wants to know how many yards of fence he will need. The fence has a length of 60 feet and a width of 30 feet. To find the total length of the fence in yards, we first calculate the perimeter of the rectangular fence which is 2 x (length + width). So, the perimeter in feet is 2 x (60 + 30) = 180 feet. Since 1 yard is equal to 3 feet, we divide the total number of feet by 3 to get the measurement in yards: 180 feet / 3 = 60 yards. Therefore, Mr. Fry will build 60 yards of fence.
Sally has a photograph that has an area of 35 square inches. She creates 2 enlargements of the photograph. The enlargements have areas of 140 square inches and 560 square inches. In each photograph, the length is 1 2/5 times the width. Select which of thr following could be th dimensions of the original photograph or one of the enlargements. Mark all that apply
5 inches by 7 inches
20 inches by 28 inches
7 inches by 20 inches
21 inches by 15 inches
10 inches by 14 inches
Answers
A = (w) * (l)
Where,
w: width
l: long
Substituting:
35 = (w) * (1.4w)
35 = 1.4 * w ^ 2
w = root (35 / 1.4)
Dimensions of the original photograph:
w = 5 in
l = 1.4 * (5) = 7 in
Dimensions of extension 1:
k = (140) / (35) = 4
w = 4 * 5 = 20 in
l = 4 * 7 = 28 in
Dimensions of extension 2:
k = (560) / (35) = 16
w = 16 * 5 = 80 in
l = 16 * 7 = 112 in
Answer:
5 inches by 7 inches
20 inches by 28 inches
The potential dimensions that could represent the original photograph and its enlargements, with the length being 1 2/5 times the width, are 5 by 7 inches for the original photograph, and 20 by 28 inches and 10 by 14 inches for the enlargements.
To find the dimensions of Sally's original photograph and the enlargements with the area having the given ratio of length to width as 1 2/5, we need to understand the relationship between the area of two similar objects and their linear dimensions. We are given that the original photograph has an area of 35 square inches, and the enlargements have areas of 140 and 560 square inches. With the length being 1 2/5 times the width in each case, we can work out the possible dimensions for these photographs.
Now, let's consider the list of dimensions provided and determine which ones correspond to an area ratio that matches the original photograph or the enlargements:
5 inches by 7 inches: This has an area of 5 x 7 = 35 square inches, so it could be the original photograph.20 inches by 28 inches: This has an area of 20 x 28 = 560 square inches, which is one of the enlargements.7 inches by 20 inches: The ratio of length to width here is not 1 2/5, so this option is not correct.21 inches by 15 inches: This does not have an area that matches either the original photograph or the enlargements and the ratio of length to width is also not 1 2/5.10 inches by 14 inches: This gives an area of 10 x 14 = 140 square inches, which matches the first enlargement.Conclusively, only some of the dimensions given match the requirements: 5 inches by 7 inches for the original photograph, 20 inches by 28 inches and 10 inches by 14 inches for the enlargements. They adhere to the concept that the ratio of their areas equals the ratio of the squares of their linear dimensions due to scaling.
A large tank is filled to capacity with 400 gallons of pure water. brine containing 3 pounds of salt per gallon is pumped into the tank at a rate of 4 gal/min. the well-mixed solution is pumped out at the same rate. find the number a(t) of pounds of salt in the tank at time t. a(t) = lb
Answers
Final answer:
The student's question involves setting up and solving a differential equation for the amount of salt in a tank where brine is added and mixed solution is removed at constant rates.
Explanation:
The problem is related to a differential equation modeling the amount of salt in a tank of water where the concentration changes over time. We are given a tank with an initial volume of 400 gallons of pure water. Brine with 3 pounds of salt per gallon is added at a rate of 4 gallons per minute, and the well-mixed solution leaves the tank at the same rate.
To find the number of pounds of salt a(t) in the tank at any time t, we can set up a differential equation based on the rates of salt entering and leaving the tank:
[tex]\(\frac{dA}{dt} = rate_{in} - rate_{out}\)[/tex]
Where A represents the amount of salt in the tank, \(rate_{in}\) is the rate at which salt enters the tank, and \(rate_{out}\) is the rate at which salt leaves the tank.
[tex]\(rate_{in} = 3 pounds/gallon \times 4 gallons/minute = 12 pounds/minute\)[/tex]
[tex]\(rate_{out} = \frac{A(t)}{400} \times 4 gallons/minute = \frac{A(t)}{100} pounds/minute\),[/tex] since the concentration of salt leaving is[tex]\(\frac{A(t)}{400}\) pounds/gallon.[/tex]
The differential equation becomes:
[tex]\(\frac{dA}{dt} = 12 - \frac{A}{100}\)[/tex]
This equation can be solved using the separation of variables or an integrating factor method, depending on the student's level of mathematical knowledge.

Jeanne thinks that x+x is the same as x•x. Is this true? Why? Why not?
Answers
and x+x means "x plus x" or "x added to x"
let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x•x" is false, then it is not true
let's try x=4
x+x=x•x
4+4=4•4
8=16
false
so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x•x, we would get that it is only true for x=2 and x=0)
it is not always true
It depends on the number. Generally, it is false, expect in a few certain cases, such as 2 for example, as:
2 + 2 = 4
2 x 2 = 4
however, most other numbers do not work, such as, for example, 5
5 + 5 = 10
5 x 5 = 25
So it really depends on what "x" is.

Explanation:The intersection of two planes can be found by solving the system of equations formed by the equations of the planes.
To find the intersection, we can set the two equations equal to each other and solve for x, y, and z.
Rewrite the equations in standard form: 5x - 5 + 2y + z + 1 = 0 and x - 1 + 7y - z - 1 = 0Add the equations together: 6x + 9y = 4Solve for x in terms of y: x = (4 - 9y) / 6Substitute the value of x into one of the original equations to solve for z: 5((4 - 9y) / 6 - 1) + 2y + (z + 1) = 0Simplify and solve for z: z = -3 - (23y/6)Therefore, the intersection of the two planes is given by the equations x = (4 - 9y) / 6, y = y, and z = -3 - (23y/6), where y can be any real number.
tevin is 202 years old Catherine is 30 years old how many years until Tevin age is 5 * Katherine's age
Answers
tevin+x = 5 times (catherine+x)
202+x=5(30+x)

minus 150 both sides
52=4x
divide both sides by 5
13=x
in 13 years
To find out how many years until Tevin's age is 5 times Katherine's age, we set up an equation and solve for x, finding that it will take 13 years.
The question is asking us to find out how many years until Tevin's age is 5 times Katherine's age. Let's denote the number of years until this happens as 'x'.
Currently, Tevin is 202 and Katherine is 30.
In x years, Tevin will be 202 + x years old and Catherine will be 30 + x.
Therefore, we want to find x such that:
202 + x = 5(30 + x)
This can be solved as follows:
202 + x = 150 + 5x
Now, we subtract 5x from both sides:
202 - 4x = 150
Subtract 202 from both sides:
-4x = -52
Divide by -4:
x = 13
Therefore, it will take 13 years for Tevin's age to be 5 times Katherine's age.

Answers
Answer:
The guinea pig is 210 mm longer than Naomi's fish
or
The guinea pig is 21 cm longer than Naomi's fish
Step-by-step explanation:
Remember that
1 cm=10 mm
Convert cm to mm
guinea pig ------> 25 cm=25*10=250 mm
Subtract the length of Naomi's fish from the length of her guinea pig
so
250-40=210 mm
Convert to cm
210 mm=210/10=21 cm
