WATER DEPTH An echo sounder is a device used to determine the depth of water by measuring the time it takes a sound produced just below the water surface to return, or echo, from the bottom of the body of water. The accuracy of an echo sounder is the positive difference between the depth of water reading on the echo sounder and the actual depth of water w. Write two absolute value expressions equivalent to the accuracy of an echo sounder.
Answers
The absolute value expressions of the echo sounder are |r - w| and |w - r|
How to determine the absolute value expressions of the echo sounder?The statement in the question is represented as
The accuracy of an echo sounder is the positive difference between ...
To solve further, we use the following representations
Depth of water reading = r
Actual depth = w
So, the statement becomes
The accuracy of an echo sounder is the positive difference between r and w
The difference can be represented as
Difference = r - w or Difference = w - r
Represented as absolute value expressions
Difference = |r - w| or Difference = |w - r|
Hence, the expressions are |r - w| and |w - r|

4x + 3y = -24 (option D)
Explanation:To determine the orrect option, we would find the equation of the line.
Equation of line: y = mx + c
m = slope, c = y-intercept
Using the slope formula:
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex]We would use any two points on the graph.
Using points: (-6, 0) and (0, -8)
[tex]\begin{gathered} x_1=-6,y_1=0,x_2=0,y_2\text{ = -}8 \\ m\text{ = }\frac{-8-0}{0-(-6)} \\ m\text{ =}\frac{-8}{0+6}=\frac{-8}{6}=-\frac{4}{3} \end{gathered}[/tex]The y intercept is the point where the line crosses the y axis and the value of x is zero. It crosses the line at y = -8
The equation of line becomes:
y = -4/3 x + (-8)
y = -4/3x - 8
Multiply both sides by 3:
3(y) = 3(-4/3 x) - 3(8)
3y = -4x - 24
3y + 4x = -24
4x + 3y = -24 (option D)

Answers
There are 2 feet in real life be 3 inches long in the scale drawing.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The stage, which is 56 feet long in real life, is 84 inches long in the scale drawing.
Let the x feet in real life be 3 inches long in the drawing.
According to the given question, we can write a ratio as
56 feet : 84 inches = x feet : 3 inches
⇒ 56 / 84 = x / 3
Apply the cross-multiplication operation,
⇒ 56 × 3 = x × 84
⇒ 168 = 84x
⇒ 84x = 168
⇒ x = 168 / 84
⇒ x = 2
Therefore, there are 2 feet in real life be 3 inches long in the scale drawing.

Eric ordered a set of red and yellow pins. He received 70 pins in all. 21 of the pins were red. What percentage of the pins were red?
Answers
The percentage of red pins in total pins ordered by Eric is 30%.
According to the question,
We have the following information:
Eric received 70 pins in all.
21 of the pins are red.
Now, we will find the percentage of red pins:
Percentage of red pins = (Number of red pins*100/total number of pins)
Percentage of red pins = (21*100)/70
Percentage of red pins = 2100/70
Percentage of red pins = 30%
(In the same way, we can also find the number and percentage of yellow pins from the total pins.)
Hence, the percentage of red pins in total pins ordered by Eric is 30%.

Hello!
First, let's write the coordinates of each vertex of this parallelogram:
• A (-4, 2)
,• B (2, 2)
,• C (5, -2)
,• D (-1, -2)
As line AB is parallel to the x-axis, we can find its measurement without formulas. We just need to count the number of squares from one point to the other.
So,
AB = 6 units.We will follow the same reasoning to calculate CD (because it's also parallel to the x-axis).
CD = 6 units.Now we have to use the formula of the distance between two points to calculate the sides BC and DA. The formula is:
[tex]d_{A,B}=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}[/tex]As we know the formula, let's replace it with the coordinates:
BC: 5 units[tex]\begin{gathered} d_{B,C}=\sqrt{\left(x_C-x_B\right)^2+\left(y_C-y_B\right)^2} \\ d_{B,C}=\sqrt{(5-2)^2+(-2-2)^2} \\ d_{B,C}=\sqrt{3^2+(-4)^2} \\ d_{B,C}=\sqrt{9+16} \\ d_{B,C}=\sqrt{25} \\ d_{B,C}=5\text{ units} \end{gathered}[/tex]DA: 5 unitsWe can solve it using the same formula as I used to solve BC, but now I'll show you how to solve it using Pythagoras Theorem (I think it will be easier). Look:
Solving by Pythagoras, we'll obtain:
[tex]\begin{gathered} x^2=4^2+3^2 \\ x^2=16+9 \\ x^2=25 \\ x=\sqrt{25} \\ x=5\text{ units} \end{gathered}[/tex]Remembering: the perimeter is the sum of all the sides of a figure. So, we will have:

(7x-2)°

(11x - 34)°
Answers
The degrees of the following expression are
(7x-2)° => x = 2/7°
18y° => y = 0°
(11x - 34)° => x = 34/11°
Degrees:
Degree is the unit of measure is used to measure the magnitude of an angle.
1 degree = 1/360 of a complete revolution in magnitude.
Given,
Here we have the following expressions
(7x-2)°
18y°
(11x - 34)°
Now, we have to find the value of x and y from it.
In order to find the value x and y , we have to equate every equation with 0. then we get the value of variables x and y.
When we take the first expression, and then we have to equate it with zero, then we get,
(7x - 2)° = 0°
7x = 2°
x = 2/7°
Therefore, the value of x is 2/7°.
Now, we have to take the second one and equate it with zero, then we get,
18y° = 0
y = 0°
Therefore, the value of y is 0°.
Finally, the value of the expression in degrees,
11x - 34° = 0
11x = 34°
x = 34/11°
Therefore, the value of x is 34/11 degrees.

(g ∘ f)(6) = 216
Step-by-step explanation:
Pre-SolvingWe are given the functions f(x) = 2x - 6 and g(x)=x³
We want to find the value of (g∘f)(6), where we first find the value of f(6), and then substitute that value into g(x).
SolvingSubstitute 6 as x in f(x)=2x-6.
f(6)=2(6)-6
Multiply
f(6)=12-6
Subtract
f(6)=6
Now substitute 6, which is the value of f(6) as x in g(x) = x³.
g(6)=6³ = 6 * 6 * 6 = 36 * 6 = 216
The value of g(6) is the same as the value of (g ∘ f)(6), as the 6 that we plugged into g(x) is the value of f(6).
Therefore, (g ∘ f)(6) = 216.

containing no bluegrass seed (0%) should be added to the seed mixture for a resulting
blend that is 20% bluegrass seed? Construct a table, then solve.
Answers
Step-by-step explanation:
what table is your teacher taking about ?
in any case this is resistive easy to solve
80 pounds of 30% with x pounds of 0% result in 80+x pounds of 20% :
80×0.3 + x×0 = (80 + x)×0.2 = 80×0.2 + x×0.2
80×0.1 = x×0.2
x = 80×0.1/0.2 = 80/2 = 40 pounds
so, 40 pounds of 0% have to be added to the 80 pounds of 30% to get a mixture of 20% (80+40 = 120 pounds).
