Answer:
1. 0.30
2.4 over 20
3. x is greater than 1.5
4. 19.2
5. 468.11
Step-by-step explanation:
1) 1.4m = 0.42.
Divide both sides by 1.4
1.4m/1.4 = 0.42/1.4
m = 0.30
2) 13/20=j+9/20
Flip equation
j + 9/20 = 13/20
Substract 9/20 from both sides
j + 9/20 - 9/20 = 13/20 - 9/20
j = 13 - 9/20
j = 4/20
3) x − 1.3 = 1.5?
Add 1.3 to both sides
x - 1.3 + 1.3 = 1.5 + 1.3
x = 2.8
So, x is greater than 1.5
4) x/6 + 0.4 =3 + 0.6
Substract 0.4 from both sides
x/6 + 0.4 - 0.4 = 3 + 0.6 -0.4
x/6 = 3 + 0.2
x/6 = 3.2
Multiply both sides by 6
x/6 • 6 = 3.2 • 6
x = 19.2
5) k − 173.54 = 294.57.
Add 173.54 to both sides
k - 173.54 + 173.54 = 294.57 + 173.54
k = 468.11
The value of m from the given equation is 0.3.
The given equation is 1.4m = 0.42.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
1) 1.4m = 0.42
⇒ m = 0.42/1.4
⇒ m = 0.3
2) 13/20 = j+9/20
⇒ j = 13/20 - 9/20
⇒ j = 4/20
⇒ j = 1/5
3) x - 1.3 = 1.5
⇒ x = 1.5 + 1.3
⇒ x = 2.8
4) x/6 + 4/10 = 3 + 6/10
⇒ x/6+0.4=3.6
⇒ x/6 = 3.2
⇒ x = 19.2
5) k − 173.54 = 294.57
⇒ k = 294.57+173.54
⇒ k = 468.11
Therefore, the value of m from the given equation is 0.3.

A square swimming pool is surrounded by a cement sidewalk that is 3 feet wide. Enter two different function representations for the total area that the swimming pool and sidewalk enclose, A(x), if the length of the pool is x feet long
Step-by-step explanation:
the area function for the square pool itself is
A(x) = x² ft²
the area function for the pool and its sidewalk is
A(x) = (x + 6)² = x² + 12x + 36 ft²
simply because in this case the side length of the square is x+3+3 ft long (3ft added on both edges).

b. Find the depth of a submerged object if the pressure is 672 pounds per square foot.
The pressure is 672 pounds per square foot at a depth of 10.5 feet.
When a force is delivered to an object's surface perpendicularly to the region across which it is applied, the force is known as pressure (symbol: p or P).
The pressure in relation to the surrounding air is known as gauge pressure, also spelled gage pressure.Pressure is expressed using a variety of units. The standard unit of pressure in the imperial and U.S. customary systems is the pound-force per square inch (psi), which is equal to one newton per square meter (N/m²) in the SI. Some of these conclusions come up as a result of dividing a unit of force by a unit of area.a. The given formula is is P=64d

A farmer with 1700 m of fancy ones to enclose a rectangular plot the borders on a river if no fence is required along the river what is the largest area that can be enclosed?
Answer
Largest Area that can be enclosed = 361250 m²
Explanation
Let the length of the fencing along the river be L
Let the width of the fencing be W
A sketch of the problem will make it clearer
Perimeter = L + 2W
Perimeter is giving as the total length of the fencing to be 1700 m
L + 2W = 1700
L = 1700 - 2W
The area of the structure is given as
Area = LW
The area is what we want to maximize
Recall, L = 1700 - 2W
Area = LW = (1700 - 2W) × W = 1700W - 2W²
A = 1700W - 2W²
At maximum point, the derivative of any function is zero
Hence,
(dA/dW) = 1700 - 4W
At maximum point,
(dA/dW) = 0
1700 - 4W = 0
4W = 1700
Divide both sides by 4
(4W/4) = (1700/4)
W = 425 m
Recall, L = 1700 - 2W
L == 1700 - 2(425)
L = 1700 - 850
L = 850 m
Maximum Area
= (Length at maximum area) × (Width at maximum area)
= 850 × 425
= 361250 m²

A ball is dropped from a height of 180 inches onto a level floor. After the second bounce it is still 5 inches off the ground. Presuming that the height the ball bounces is always the same fraction of the height reached on the previous bounce, what is that fraction?
The fraction which is a constant is equal to 1/6
How to find the fraction of the bouncing ballGiven data
A ball is dropped from a height of 180 inches
After the second bounce it is still 5 inches
the height the ball bounces is always the same fraction of the height reached on the previous bounce
Let the first height be x, this the initial drop height = 180
Let the second height be, the first bounce y
Let the third height be w, the second bounce = 5
the fraction is said to be:
height of y / height of x = height of w / height of y
y / x = w / y
y / 180 = 5 / y
y^2 = 180 * 5
y^2 = 900
y = √900
y = 30
the fraction is then 30 / 180 = 1 / 6

Solve The Equation
-1.9 = 0.5(p +1.7)
Whoever answer first gets brainliest!
Answer:
p=-5.5Step-by-step explanation:
To solve this equation, use the distributive property. Isolate the difference between the numbers from one side of the equation.
Distributive property:
A(B+C)=AB+AC
-1.9 = 0.5(p +1.7)
First, switch sides.
0.5(p+1.7)=-1.9
Divide by 0.5 from both sides.
[tex]\sf{\dfrac{0.5\left(p+1.7\right)}{0.5}=\dfrac{-1.9}{0.5}}[/tex]
Solve.
-1.9/0.5=-3.8
p+1.7=-3.8
Then, you subtract by 1.7 from both sides.
p+1.7-1.7=-3.8-1.7
Solve.
Add or subtract the numbers from left to right.
-3.8-1.7=-5.5
[tex]\rightarrow \boxed{\sf{p=-5.5}}[/tex]
Therefore, the correct answer is p=-5.5.
I hope this helps, let me know if you have any questions.
The value of p on the equation - 1.9 = 0.5(p +1.7) is - 5.5.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, we have to solve for p in the equation - 1.9 = 0.5(p +1.7).
0.5(p + 1.7) = - 1.9
First, we'll distribute the terms.
0.5p + 0.85 = - 1.9.
0.5p = - 1.9 - 0.85.
0.5p = - 2.75.
p = - 2.75/0.5.
p = - 5.5

Angle 4 is a vertical angle to the 115 degrees angle. Therefore, it must be the same in degree measure. So, we know angle 4 is 115 degrees.

Zachary has a container of worms for fishing. When empty, the mass of the container is 225 grams. With the worms in it, the container has a total mass of 751.4 grams. Each worm has a mass of 11.2 grams. How many worms are in the container? Write and solve an equation to model this equation.
Solving a linear equation we will see that there are 47 worms in the container
How many worms are in the container?We know that the mass of the container is 225 grams, and the mass of each worm is 11.2 grams.
Then if there are x worms on the containers, the total mass is:
M(x) = 225g + x*11.2g
In this case, we know that the total mass is 751.4 grams, then we can write:
751.4 g = 225g + x*11.2g
Solving this linear equation we get:
751.4g - 225g = x*11.2g
526.4g = x*11.2g
