Write a congruency statement for the pair of triangles.
Answer:
ΔABP is congruent to ΔBAQ
ΔABP ≡ ΔBAQ
Explanation:
We are given two triangles; ΔABP and ΔABQ
In these two triangles, we have:
AB as a common side
∠ABP = ∠BAQ
AQ = BP
We can conclude that these two triangles are congruent by SAS (side-angle-side) postulate which states that:
"When two sides and the included angle between them in the first triangle are congruent to the corresponding two sides and the included angle between them in the second triangle, then the two triangles are congruent"
Note that when writing congruency statements, the order of the letters is critical as each angle/side in the first triangle must be congruent to its corresponding angle/side in the second triangle.
Based on the above, the congruency statement would be:
ΔABP is congruent to ΔBAQ

Help please. Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
A.5√2 /2
B.5√3
C.5√2
D.5√3 /2
Answer: The value of the variable is [tex]x=\dfrac{5\sqrt2}{2}.[/tex]
Step-by-step explanation: We are given to find the value of the variable 'x' in the figure.
We can see that the figure is a right-angled triangle with the length of the hypotenuse as follows:
h = 5 units.
Now, with respect to the angle of measure 45°, the length of the perpendicular is x units.
That is, p = x units.
From relations between trigonometric ratios, we have
[tex]\sin 45^\circ=\dfrac{\textup{perpendicular}}{\textup{hypotenuse}}\\\\\\\Rightarrow \dfrac{1}{\sqrt2}=\dfrac{p}{h}\\\\\\\Rightarrow \dfrac{1}{\sqrt2}=\dfrac{x}{5}\\\\\\\Rightarrow x=\dfrac{5}{\sqrt2}\\\\\\\Rightarrow x=\dfrac{5\sqrt2}{(\sqrt2)^2}\\\\\\\Rightarrow x=\dfrac{5\sqrt2}{2}.[/tex]
Thus, the value of the variable is [tex]x=\dfrac{5\sqrt2}{2}.[/tex]
What is the slope of a line that is perpendicular to the line v= 3/4x-6?
A. 3/4
B. -4/3
C. -3/4
D. 1/6
The slope of line which is given to be perpendicular to the line represented by equation "v = (3/4)x - 6" is : (b) -4/3.
To determine the slope of a line that is perpendicular to the given line v = (3/4)x - 6, we use the property that perpendicular lines have slopes that are "negative-reciprocals" of each other.
The slope of the given line is 3/4. To find the slope of the perpendicular line, we take the negative reciprocal of 3/4.
The negative reciprocal of 3/4 is -4/3. So, the slope of the line that is perpendicular to the given-line v = (3/4)x - 6 is -4/3.
Therefore, the correct answer is (b) -4/3.

A swimming pool is 15 by 30 feet and a consistent 5 feet deep. you are painting the walls and floor of the pool. if a gallon can of paint covers 250 square feet, how many gallon cans would you need to buy
the bottom of the pool is 15 x 30 = 450 sq feet.
you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet
then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet
for a total of 450 +300 +150 = 900 square feet
1 can covers 250 sq ft
so 900/250 = 3.6
so you would need 4 cans of paint
find the center of the circle that can be circumscribed about triangle EFG, E(6,4) F(6,2) and G(10,2)
Final answer:
The center of the circumscribed circle about triangle EFG with given vertices is found by calculating the perpendicular bisectors of the triangle's sides and locating their intersection point, which is the center (8,3).
Explanation:
To find the center of the circumscribed circle about triangle EFG with vertices E(6,4), F(6,2), and G(10,2), we need to determine the perpendicular bisectors of at least two sides of the triangle and then find their intersection point, which will be the center of the circumscribed circle.
First, find the midpoint of side EF, which has the same x-coordinate (since E and F have the same x-coordinate), so the midpoint is (6,3).Next, we need the equation of the perpendicular bisector of EF. Since EF is vertical, its perpendicular bisector is a horizontal line that passes through the midpoint, hence the equation is y = 3.Then, find the midpoint of side FG. As the endpoints have the same y-coordinate, the midpoint will have that y-coordinate (2) and the x-coordinate will be the average of the x-coordinates of F and G, which is (6+10)/2 = 8. So, the midpoint of FG is (8,2).The slope of side FG is 0 (since it's horizontal), so the slope of its perpendicular bisector is undefined, meaning it's a vertical line. Consequently, the equation of this perpendicular bisector is x = 8.Last, by solving the system of equations formed by the two perpendicular bisectors x = 8 and y = 3, we find the intersection point, which is the center of the circumscribed circle: (8,3).Determine the angular velocity in radians per second of 4.9 revolutions in 5 seconds. Use 3.14 for pi.

b) 117 miles per hour

Find the measure of each angle: Complementary angles with measures (5x)° and (4x−18)°.
The measure of the complementary angles (5x)° and (4x−18)° are 60° and 30° respectively.
What are complementary angles?Complementary angles are a pair of angles whose sum is always equal to 90°.
If A and B are complementary angles, then A + B = 90°.
How to solve the given question?In the question, we are asked to find the measure of each angle, given that the angles (5x)° and (4x - 18)° are complementary angles.
As we know that these angles are complementary, we can write the equation to solve for x as,
5x + (4x - 18) = 90
or, 5x + 4x - 18 = 90
or, 9x = 90 + 18 = 108
or, x = 108/9 = 12.
Therefore, the value of these angles are:
(5x)° = (5*12)° = 60°.(4x - 18)° = (4*12 - 18)° = (48 - 18)° = 30°.Therefore, the measure of the complementary angles (5x)° and (4x−18)° are 60° and 30° respectively.

Find all polar coordinates of point p where p = ordered pair 5 comma pi divided by 3.
Find all polar coordinates of point p where p = ordered pair 5 comma pi divided by 3.
The polar coordinate of any point can be written as:
(r, θ) = (r, θ + 2nπ) --> when positive
(r, θ) = [ - r, θ + (2n + 1)π ] --> when negative
where n is any integer.
The polar coordinates of this given point P is: P = (r, θ) = (5, π/3).
When the value of r is positive, the polar coordinate is written as P= (5, π/3) = (5, π/3 + 2nπ)
where n is any integer.
When the value of r is negative, the polar coordinate is written as P = (5, π/3) = [ - 5, π/3 + (2n + 1)π] where n is any integer.
Therefore all polar coordinates of point P are (5, π/3 + 2nπ) and [ - 5, π/3 + (2n + 1)π ].
The polar coordinates of point P are (5,[tex]\pi[/tex]/3) = (5, [tex]\pi/3[/tex] + 2n[tex]\pi[/tex]) to (-5,[tex]\pi[/tex]/3) = (-5, [tex]\pi/3[/tex] + 2n[tex]\pi[/tex])
The coordinates of point p are given as:
p = (5, [tex]\pi[/tex]/3)
A point represented as (r, θ) has the following polar coordinates
(r, θ + 2n[tex]\pi[/tex]) for positive r, and (- r, θ + [2n + 1][tex]\pi[/tex]) for negative r
By comparing (r, θ) and (5, [tex]\pi[/tex]/3), we have:
r = 5
[tex]\theta = \pi/3[/tex]
So, we have:
(r,[tex]\theta[/tex]) = (r, [tex]\theta[/tex] + 2n[tex]\pi[/tex])
The equation becomes
(5,[tex]\pi[/tex]/3) = (5, [tex]\pi/3[/tex] + 2n[tex]\pi[/tex])
Also, we have:
(-5,[tex]\pi[/tex]/3) = (-5, [tex]\pi/3[/tex] + 2n[tex]\pi[/tex])
Hence, the polar coordinates of point P are (5,[tex]\pi[/tex]/3) = (5, [tex]\pi/3[/tex] + 2n[tex]\pi[/tex]) to (-5,[tex]\pi[/tex]/3) = (-5, [tex]\pi/3[/tex] + 2n[tex]\pi[/tex])

As a salesperson at Scrapbooks and Treasures, Alysse receives a monthly base pay plus commision on all that she sells. If she sells $400 worth of merchandise in one month, she is paid $388. If she sells $1,000, she is paid $520. Find Alysse's salary when she sells $3,300 worth of merchandise.
Answer:
Step-by-step explanation:
In order to solve this we just have to create a system of equations, because we have to unknown values, for the base salary we are going to use X and for the comission we will use Y, now we know that when she sold $400 in merchandise she earned $388 and and when she sold $100 se got paid $520 both equations would look like this:
[tex]x+400y=388\\x+1000y=520][/tex]
Now we can solve them by elimination, multiplying one function by -1.
[tex](-1)(x+400y=388)= -x-400y=-388\\x+1000y=388\\1000y-400y=132\\600y=388\\y=\frac{132}{600} \\y=0.22=22%[/tex]
Now we know that the percentage that she earns is 22% of the merchandise she sells.
Now to know how much does she makes on her base pay we just put the value into one of the functions:
[tex]x+1000y=520\\x+1000(.22)=520\\x+220=520\\x=300[/tex]
So her base pay is $300.
To calculate how much she will earn when she sells $3,300 in merchandise we just put that value into the formula:
[tex]x+3300y=\\300+3300(.22)\\300+726=1026[/tex]
So when she sells 3300 she will make 1026 total.
