Answer:
9/7
Step-by-step explanation:
Since the pitch is found the same way as the slope of a line
Tangent= slope = pitch
But; Tangent = Opposite/Adjacent
Therefore;
Tan x = 9/7
Thus;
The pitch of the roof is 9/7

You can't build a triangle with those dimensions
How much water must be evaporated from 36 ounces of a 8% salt solution to make a 9% salt solution?
To obtain a solution that is 9% salt, how many ounces of water must be evaporated
(Simplify your answer.)
Answer:
4 oz of water must be evaporated
Step-by-step explanation:
If we let x represent the amount of water to be evaporated, the relation between the solutions is ...
0.08 · 36 oz = 0.09 · (36 -x) oz
0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36
x = 36· 0.01/0.09 = 36/9 = 4
4 ounces of water must be evaporated.
Answer:
Step-by-step explanation:
The price of gas was $1.80 in September then $2.07 in October. Find the percent change from September to October.
twenty seven percent.
The percent change in the price of gasoline from September to October is calculated using the formula for percent change. Subtracting the September price from the October price and dividing by the September price yields a 15% increase.
To calculate the percent change in the price of gasoline from September to October, we use the formula for percent change, which is
(New Price - Old Price) / Old Price
x 100%. In this case, the price in September was $1.80, and the price in October was $2.07.
The percent change can be calculated as follows:
Subtract the old price from the new price: $2.07 - $1.80 = $0.27.Divide the change by the original price: $0.27 / $1.80.Convert this number to a percentage by multiplying by 100, which gives us the percent change: ($0.27 / $1.80)Therefore, the percent change in the price of gasoline from September to October is 15%.

Which equation represents the graph
Answer:
y= 3|x|+5
Step-by-step explanation:
Remember the graph for |x| is shown on the attached picture
Since the picture you show tell us that y=5 when x=0
we have something like the following y=a|x|+5, where 'a' is a constant that represents the slope of the line (whether is the line from one side of the 'y' axis or from the other), we can see that, when x=1, y=8, so we have another point
we can use the equation for slopes using points 1 (0,5) and 2 (1,8)
thus we have that [tex]a=\frac{8-5}{1-0}=3[/tex]
So the answer is y= 3|x|+5
determine if the given point is a solution of the given system of linear equations y=3× + 6 y= -2× + 9 (3,3)
Answer:
The point (3, 3) is not a solution of the first equation, therefore is not a solution of the given system of equations.
Step-by-step explanation:
[tex]y=3x+6\ and\ y=-2x+9[/tex]
[tex](3,\ 3)\to\text{put x = 3 and y = 3 to the equations of the functions}\\\text{and check the equality.}\\\\y=3x+6\\\\3=3(3)+6\\3=9+6\\3=15\qquad\text{FALSE!}[/tex]
To determine if the given point (3,3) is a solution of the given system of linear equations y=3x+6 and y=-2x+9, we substitute the values of x and y into both equations and check if the equations hold true. If both equations are true, then the given point is a solution of the system of equations.
Explanation:To determine if the given point (3,3) is a solution of the given system of linear equations y=3x+6 and y=-2x+9, we substitute the values of x and y into both equations and check if the equations hold true.
Substitute x = 3 and y = 3 into the first equation: 3 = 3(3) + 6. Substitute x = 3 and y = 3 into the second equation: 3 = -2(3) + 9. If both equations are true, then the given point (3,3) is a solution of the system of equations.
Let's perform the calculations:
3 = 3(3) + 6 simplifies to 3 = 9 + 6, which is false. 3 = -2(3) + 9 simplifies to 3 = -6 + 9, which is true.
Since only one of the equations is true, the given point (3,3) is not a solution of the system of equations.

Find the value of x.
Answer options: 82, 88, 76, 94
Answer:
x = 76°
Step-by-step explanation:
We can solve this by using the angles of intersecting chords theorem. This tells us that when two chords intersect inside a circle, the angle formed is half of the sum of the intercepted arcs of the angle.
This implies that the angle 94° should be half of the sum of Arc measuring x° and the arc measuring 112°. So we can write the equation as:
[tex]94=\frac{1}{2}(x+112)\\[/tex]
We can simplify and solve for x:
[tex]94=\frac{1}{2}(x+112)\\\\94=\frac{1}{2}x+56\\94-56=\frac{1}{2}x\\38=\frac{1}{2}x\\x=38*2=76[/tex]
Hence, x = 76°
What is the solution to the following system of equations?
Answer:
D. (2,1)
Step-by-step explanation:
Fill in the value for y from the first eq (6x-11) into the second:
-2x - 3(6x-11) = -7
Now simplify:
-2x -18x + 33 = -7
-20x = -7-33
20x = 40
x = 2
Now that we have x, plug it into the top eq to get y:
y = 6*2 - 11 = 1
Et voila, x=2 and y=1, so the solution is (2,1).
Answer:
X= 2 and Y=1
Step-by-step explanation:
✯Hello✯

Factor the GCF:

A.) -1(4y^2-12y+16)
B.) -4y(y^2-3y+4)
C.) -(y^2-3y+4)
D.) -4(y^2+3y-4)
The expression for when the GCF is factored is -4(y² - 3y + 4). Option D
To factor out the Greatest Common Factor (GCF) from the expression [tex]-4y^2 + 12y - 16[/tex] first, find the GCF of the terms.
The GCF of the coefficients 4, 12, and 16 is 4.
Additionally, there is a common factor of y² in all terms.
Now, we have to actor out the GCF, which is -4, we get;
-4(y² - 3y + 4)
Therefore, the expression -4(y² - 3y + 4) represents the factor GCF from the original expression

Answer:
C) 3(5)^6
Step-by-step explanation:
Note the amount of 5's inside the expression and 3's inside the expression.
In the given expression (3 x 5 x 5 x 5 x 5 x 5 x 5), there are 6 5's and 1 3's.
Note that, when changing multiplication into powers, the amount of the same number multiplied together will equal the number you put as a power. For example:
5 x 5 = 5²
5 x 5 x 5 = 5³
In this case:
5 x 5 x 5 x 5 x 5 x 5 = 5^6
Note that there is still a 3 multiplied inside the expression, and so remember to keep it in the answer.
3(5)^6, or C) is your answer.

what is the constant of proportionality for the relationship between the length of the arc intercepted by 80 angle and the radius of the circle ?
Eight hundred thousands
Final answer:
The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.
Explanation:
The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.
This can be determined by using the formula for arc length: L = 2πr(A/360), where L is the length of the arc, r is the radius of the circle, and A is the angle in degrees. Since we know that A = 80 degrees, we can substitute the values into the formula to find the constant of proportionality.
L = 2πr(80/360) = (π/9)r

Answer:
[tex]V=250\ cm^{3}[/tex]
Step-by-step explanation:
step 1
Find the length of the base L
we know that
The surface area of a rectangular prism is equal to
[tex]SA=2B+PH[/tex]
where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
substitute
[tex]SA=2(LW)+2(L+W)H[/tex]
we have
[tex]W=5\ cm[/tex]
[tex]H=10\ cm[/tex]
[tex]SA=250\ cm^{2}[/tex]
substitute in the formula and solve for L
[tex]250=2(5L)+2(L+5)10[/tex]
[tex]250=10L+20L+100[/tex]
[tex]30L=250-100[/tex]
[tex]L=5\ cm[/tex]
step 2
Find the volume of the rectangular prism
The volume is equal to
[tex]V=(LW)H[/tex]
we have
[tex]W=5\ cm[/tex]
[tex]L=5\ cm[/tex]
[tex]H=10\ cm[/tex]
