Three boards are placed end to end to make a walkway. The first board is 3 feet 7 inches long, the second board is 5 feet 4 inches long, and the third board is 3
feet 10 inches long. How long is the walkway?
Write your answer in feet and inches. Use a number less than 12 for inches.
C
Answers
The walkway is 12 feet 9 inches long.
To find the total length of the walkway, we need to add the lengths of the three boards together.
The first board is 3 feet 7 inches long, which can be written as 3'7".
The second board is 5 feet 4 inches long, which can be written as 5'4".
The third board is 3 feet 10 inches long, which can be written as 3'10".
Now, let's add the lengths together:
3'7" + 5'4" + 3'10"
When adding feet and inches, we need to carry over any extra inches beyond 12 to the feet.
Adding the inches first:
7" + 4" + 10" = 21"
Now, let's add the feet:
3' + 5' + 3' = 11'
So, the total length of the walkway is 11 feet 21 inches.
We need to convert the inches to feet by dividing by 12:
11' + 21" ÷ 12 = 11' + 1'9" = 12'9"

Answers
ANSWER
4/3 pounds of salt
EXPLANATION
We are given that Kayla mixes 1/6 pound of salt with 1/8 bucket of water to make a saline solution.
We want to find out how much salt she will need to mix with a bucket of water.
To do this, we will compare and cross multiply,
That is, let the amount of salt needed be x:
\(\begin{gathered} \frac{1}{6}\text{ pound of salt = }\frac{1}{8}\text{ bucket of water} \\ \Rightarrow\text{x pound of salt = }1\text{ bucket of water} \\ \text{Cross-multiply:} \\ 1\cdot\text{ }\frac{1}{6}\text{ = x }\cdot\text{ }\frac{1}{8} \\ \Rightarrow\text{ x = }\frac{8\cdot\text{ 1}}{6}\text{ = }\frac{8}{6} \\ \Rightarrow\text{ x = }\frac{4}{3}\text{ pounds of salt or 1}\frac{1}{3}\text{ pounds of salt} \end{gathered}\)Kayla will need 4/3 pounds of salt or 1 1/3 pounds of salt

Answer:
y = 8/27
Step-by-step explanation:
given
x = 7
y = 4x*y - 4(2)
y = 4*7*y - 8
y = 28y - 8
8 = 28y - y
8 = 27y
8/27 = y
to prove
y = 4x*y - 4(2)
8/27 = 4*7*y - 8
8/27 = 28*8/27 - 8
8/27 = 224/27 - 8
8/27 = 224 - 27*8/27
8/27 = 8/27
hence it is proved that y is 8/27 .

Using an algebraic equation to represent the word problem, the smallest integer is 1
Word ProblemThis is a way of representing mathematical problems with words. To solve this, we have to use algebraic equations or expressions.
Let the integers be represented as
xx + 2x + 4We can write an equation from the word problem given as
7 × (x + 2) = 15 + [x + (x + 4)]
7x + 14 = 15 + x + x + 4
7x + 14 = 15 + 2x + 4
collect like terms
7x - 2x = 15 - 14 + 4
5x = 5
Divide both sides by coefficient of x
5x / 5 = 5 / 5
x = 1

Kerry wants her stopping distance to not exceed 75ft. At what range of speeds can she travel?
Answers
The range of speeds that she can travel is determined as 30 mph or less.
Range of speed of KerryThe range of speed of Kerry is calculated as follows;
d = v + (v²)/20
d = (20v + v²)/20
75 = (20v + v²)/20
20(75) = 20v + v²
1500 = 20v + v²
v² + 20v - 1500 = 0
v² + 50v - 30v - 1500 = 0
v(v + 50) - 30(v + 50) = 0
(v + 50)(v - 30) = 0
v = 30 mph or - 50 mph
Thus, the range of speeds that she can travel is determined as 30 mph or less.

HURRY!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
8/21 of the lawn still needs to be mowed.
To compare fractions, we need a common denominator. The least common multiple of 7 and 3 is 21.
Miss Lianto's fraction: (2/7) x (3/3) = 6/21
Son's fraction: (1/3) x (7/7) = 7/21
To calculate how much of the lawn still needs to be mowed, we can subtract the combined fractions mowed from the total:
Combined fractions mowed: 6/21 + 7/21 = 13/21
So, Remaining fraction: 1 - 13/21 = 8/21
Therefore, 8/21 of the lawn still needs to be mowed.

Find an autonomous differential equation with all of the following properties:
equilibrium solutions at y=0 and y=3,
y' > 0 for 0
y' < 0 for -inf < y < 0 and 3 < y < inf
dy/dx = ______
Answers
dy/dx = (y-3)(y+3) is the autonomous differential equation that satisfies all of the given properties.
The autonomous differential equation that satisfies all of the given properties is dy/dx = (y-3)(y+3). This equation has two equilibrium solutions at y = 0 and y = 3, and is positive for -inf < y < 0, and negative for 0 < y < 3, and positive for 3 < y < inf.
To demonstrate this, let's consider the equation at y=-3. Since y=-3 is less than 0, the equation can be simplified to dy/dx = 6. Since 6 is positive, y' is also positive, meaning that y is increasing. Similarly, if y=3, dy/dx = 0 which is neither positive nor negative, so y remains constant. Finally, for y>3, dy/dx = -6, which is negative, so y is decreasing.
Therefore, dy/dx = (y-3)(y+3) is the autonomous differential equation that satisfies all of the given properties.
