Answers
Answer:
2/7
Step-by-step explanation:
First off you would want to get rid of the negative because a negative times a negative equal a positive making the -2/3 and -6/7 a positive then you would want to cancel out the greatest common factor of 2 making the equation now 1/3 x 6/7 then you'll want to cancel out the greatest common factor of 3 by dividing 3 by 3 and 6 by 3 making it 1/1 x 2/7 and then after you multiply you get your answer of 2/7
If using the method of completing the square to solve the quadratic equation x^2-20x+33=0, which number would have to be added to "complete the square"?
Answers
The number 67 must be added to form the complete square ( x - 10)² to solve the quadratic equation x² - 20x + 33.
Consider the quadratic equation,
x² - 20x + 33 = 0
Comparing the equation with general form of quadratic equation ax² + bx + c = 0
We have,
a = 1, b = - 20, and c = 33
x² - 20 x +33 =0
x² - 2 × 10 x + ( 10 )² - ( 10 )² + 33 =0
By using the identity ( a - b )² = a² - 2ab + b²
( x - 10)² -100 +33 =0
( x - 10)² - 67 =0
( x - 10)² = 67
Hence, the complete square:
( x - 10 )² = 67
x - 10 = ± √67
x - 10 = ± 8.1853
So,
x - 10 = 8.2
x = 10 + 8.2
x = 18.2
And;
x - 10 = - 8.2
x = 10 - 8.2 = 1.8

Compute the diameter of a circle with a circumference of 34 feet
Answers
Answer:
d ≈ 10.8 feet
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = πd ( where d is the diameter )
given C = 34 , then
πd = 34 ( divide both sides by d )
d ≈ 10.8 feet ( to 1 dec. place )
Answer:
The diameter of circle is 10.82 feet.
Step-by-step explanation:
Given :Circumference of circle = 34 feetTo Find :Radius of circle Diameter of circle Using Formulas :[tex]\longrightarrow\sf{Circumference_{(Circle)} = 2 \pi r}[/tex]
[tex]\longrightarrow\sf{Diameter_{(Circle)} = 2r}[/tex]
Where
π = 3.14r = radiusSolution :Finding the radius of circle by substituting all the given values in the formula :
[tex]\longrightarrow\sf{Circumference_{(Circle)} = 2 \pi r}[/tex]
[tex]\longrightarrow\sf{34 = 2 \pi r}[/tex]
[tex]\longrightarrow\sf{34 = 2 \times 3.14 \times r}[/tex]
[tex]\longrightarrow\sf{34 = 6.28 \times r}[/tex]
[tex]\longrightarrow\sf{ r = \dfrac{34}{6.28}}[/tex]
[tex]\longrightarrow\sf{\underline{\underline{ r \approx 5.41}}}[/tex]
Hence the radius of circle is 5.41 feet
[tex]\begin{gathered} \end{gathered}[/tex]
Now, calculating the diameter of circle by substituting the given value in the formula :
[tex]\longrightarrow\sf{Diameter_{(Circle)} = 2r}[/tex]
[tex]\longrightarrow\sf{Diameter_{(Circle)} = 2 \times r}[/tex]
[tex]\longrightarrow\sf{Diameter_{(Circle)} \approx 2 \times 5.14}[/tex]
[tex]\longrightarrow\sf{Diameter_{(Circle)} \approx 10.82}[/tex]
Hence, the diameter of circle is 10.82 feet.

Based on the given conditions.
First a farmer is conducting an experiment to determine which variety of apple tree, fuji or gala, will produce more fruit in his orchard.The orchard is divided into equally sized square plotsHe has 10 trees of each variety and randomly assigns each tree to a separate plot in the orchard.Since the plots are the things being measured, they serve as the experimental units. The explanatory variable is the type of apple trees because they induce change in the experimental unit by undergoing two distinct treatments. The experiment is being run by the farmer, and the outcome is the quantity of apples. Since each plot is being investigated separately, the orchard as a whole has no bearing on the experiment.Therefore,
The plots are experimental units in this study, then the farmer is conducting an experiment to determine which variety of apple tree, fuji or gala, will produce more fruit in his orchard. So ,the answer is the plots.

Find the value of the missing angles, marked a, b and c. Give a reason for each stage of your working.
Answers
The unknown angles of the diagram is as follows;
a = 32°b = 20°c = 128°How to find angles?The missing angles of the diagram can be found as follows:
The sum of angles in a triangle is 180 degrees.
Therefore,
32 + 128 + b = 180
160 + b = 180
b = 180 - 160
b = 20°
Therefore,
a = 32°(alternate angles)
Alternate angles are congruent.
180 - a - b = c (sum of angles on a straight line)
180 - 32 - 20 = c
c = 180 - 32 - 20
c = 128°

What is the slope of the line that passes through the points (2, -6) and (6, -12)? Write your answer in simplest form.
Answers
Answer:
4/-18 or 2/-9
Step-by-step explanation:
The slope of a straight line is a number that indicates how steep the line is. You can calculate the slope of a line by dividing the vertical change, called the rise, by the horizontal change, called the run, between two distinct points on the line.
Slope = change in y divided by change in x or rise divided by run
6 - 2 = 4
-12 - 6 = -18
Answer would be 4/-18
a bald eagle sits in his nest in a tree at the top of the mountain. the nest is 1284 feet above the ground the eagle can dive at a rate of 88 feet/second what is the eagles height h after 7 seconds? the function rule for the height of the eagle after s seconds is? after 7 seconds the eagles height is?
Answers
The function rule for the height of the eagle after s seconds is h(s) = 1284 - 88s.
The height of eagle after 7 seconds is 668 feet.
Given that:-
Height of nest = 1284 feet
Speed of the bald eagle = 88 feet/second
Hence, we can write, after s seconds,
Height of eagle after s seconds = height of the nest - Time (in seconds) * Speed of the eagle
Hence,
h(s) = 1284 - s*88
h(s) = 1284 - 88s.
From the above equation, we can find the height of the eagle after 7 seconds.
h(7) = 1284 - 88*7 = 1284 - 616 = 668 feet.

Given m || n, find the value of x and y.
Answers
Answer:
see my picture, bro. hope it can help
Answer:
x = 15
y = 50
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
The angles (8x + 10)° and y° form a linear pair.
Therefore, equate the sum of these angles to 180° and isolate y:
⇒ (8x + 10)° + y° = 180°
⇒ 8x + 10 + y = 180
⇒ 8x + 10 + y - 10 = 180 - 10
⇒ 8x + y = 170
⇒ 8x + y - 8x = 170 - 8x
⇒ y = 170 - 8x
Corresponding Angles Postulate
When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.
The angles y° and (3x + 5)° are corresponding angles and are therefore congruent:
⇒ y° = (3x + 5)°
⇒ y = 3x + 5
Substitute the second equation for y into the first equation for y and solve for x:
⇒ 3x + 5 = 170 - 8x
⇒ 3x + 5 + 8x = 170 - 8x + 8x
⇒ 11x + 5 = 170
⇒ 11x + 5 - 5 = 170 - 5
⇒ 11x = 165
⇒ 11x ÷ 11 = 165 ÷ 11
⇒ x = 15
Substitute the found value of x into one of the expression for y and solve for y:
⇒ y = 170 - 8x
⇒ y = 170 - 8(15)
⇒ y = 170 - 120
⇒ y = 50
Final solution:
x = 15y = 50heelp mee with thisssss
