△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions.
Answer:
As Given :The coordinates of the vertices of △JKL are J(3, 0) , K(1, −2) , and L(6, −2) . The coordinates of the vertices of △J′K′L′ are J′(−3, 1) , K′(−1, 3) , and L′(−6, 3) .
⇒As we can see the two triangles are congruent because length of sides are equal.i.e By SSS ΔJKL and ΔJ'K'L' are congruent.
⇒ As you can see from the figure depicted below the triangle JKL is rotated by an angle of 180° then translation of y coordinate by 1 unit up has taken place.
So , Option (3) is correct which is :△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions.

Male: Sprints- 16 Middle distance- 11 Long distance- 9 Female: Sprints- 12 Middle distance- 14 Long distance- 5 To the nearest hundredth, what is the probability that a randomly chosen female runs sprints? This obviously says that order doesn't matter as they mention "randomly chosen". I am just having trouble figuring out how to solve this.
Answers
Answer: Approx 0.39 will be the required probability.
Step-by-step explanation:
Here,Number of,
Male: Sprints=16, Middle distance=11, Long distance= 9
So, total males=36
And, Female: Sprints= 12, Middle distance=14, Long distance=5
So, total females=31
Thus, If one female randomly chosen,
Then, The probability that female runs sprint= Number of females who run sprint / total number of females
⇒ The probability that female runs sprint=12/31= 0.38709677419≈0.39

What is the radius of a circle whose equation is x2 + y2 + 8x – 6y + 21 = 0?
Answers
center(-2,4)
Answer: The required center of the given circle is 2 units.
Step-by-step explanation: We are given to find the radius of a circle with the following equation:
[tex]x^2+y^2+8x-6y+21=0~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
The standard equation of a CIRCLE with radius 'r' units and center at the point (h, k) is given by
[tex](x-h)^2+(y-k)^2=r^2.[/tex]
From equation (i), we have
[tex]x^2+y^2+8x-6y+21=0\\\\\Rightarrow (x^2+8x+16)+(y^2-6y+9)-16-9+21=0\\\\\Rightarrow (x^2+2\times x\times 4+4^2)+(y^2-2\times x\times 3+3^2)-4=0\\\\\Rightarrow (x+4)^2+(y-3)^2=4\\\\\Rightarrow (x-(-4))^2+(y-3)^2=2^2.[/tex]
Comparing the above equation with the standard equation (i), we get
radius, r = 2 units and center, (h, k) = (-4, 3).
Thus, the required center of the given circle is 2 units.
N a trip to his grandparents, donny drove 60 miles per hour for 45 minutes and 50 miles per hour for 30 minutes. how many miles did donny drive?
Answers
The solution is, donny drove 70 miles.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
here, we have,
we know that,
Speed: The ratio of distance to time.
To find the distance we use the following formula.
Given that
donny drove 60 miles per hour for 45 minutes and 50 miles per hour for 30 minutes.
so, we get,
In 45 minutes, she traveled = ( 60/60 * 45)
= (1 * 45)
=45 miles.
again, we have,
The she drove 50 miles per hour for 30 minutes.
so, we get,
In 30 minutes, she traveled = ( 50/60 * 30 )
=50/2
= 25 miles
Therefore donny drove (45+25) miles= 70 miles.
Hence, The solution is, donny drove 70 miles.

What is the maturity value of a 3-month, 14% note for $50,000? (round your answer to the nearest dollar.)
a.$57,000
b.$51,750
c.$50,000
d.$52,000?
Answers
The maturity value of a 3-month, 14% note for $50,000 is calculated by first determining the interest over the 3-month period and then adding it to the principal. The interest is $1,750, resulting in a maturity value of b) $51,750.
The maturity value of a 3-month, 14% note for $50,000 can be calculated using the formula for simple interest: M = P + (P × r × t), where M is the maturity value, P is the principal amount, r is the annual interest rate (as a decimal), and t is the time in years. Let's calculate the interest first and then add it to the principal to find the maturity value.
First, convert the annual interest rate to decimal: 14% = 0.14.
Then, because the note is for 3 months (which is 3/12 or 0.25 of a year), the time period t is 0.25.
Now, calculate the interest: I = P × r × t = $50,000 × 0.14 × 0.25 = $1,750.
Finally, add the interest to the principal to get the maturity value: M = P + I = $50,000 + $1,750 = $51,750.
So, the correct answer is b. $51,750.

Step-by-step explanation:
The distance formula gives the length of the radius:
r = √(-3-1)^2 + (- 1-2)^2 = √25 = 5
Substituting h = -3, k = -1, and r = 5 into the standard form (x - h)2 + (y - k)2 = r2, you get (x + 3)2 + (y + 1)2 = 52 = 25.

A polyhedron with 4 vertices and 6 edges would have 4 faces, according to Euler's formula.
Explanation:This question involves the understanding of Euler's formula applied on polygons. Euler's formula, as given in the question is V – E + F = 2, where V is the number of vertices, E is the number of edges, and F is the number of faces. To answer your question, we need to solve the formula for F. Let's replace V and E with the given numbers, which are 4 for vertices and 6 for edges.
So the formula becomes 4 – 6 + F = 2. Simplifying this, we get -2 + F = 2. Solving for F, we find F = 1 + 2, which means F = 4. So, a polyhedron with 4 vertices and 6 edges would have 4 faces.

Answer:
B - The melting point is a lower temperature than the boiling point.

Melting point is the temperature at which any given solid will melt. The state of the solid changes from solid to liquid.
Boiling point is the temperature at which a given liquid boils and changes to vapor state. Like water starts to boil at 100 degrees Celsius.
The boiling point of a substance cannot be lower than its melting point.

The expression V = 2x3 + 6x2 can be used to find the volume of the trapezoidal prism below. If x = 12 cm, what is the volume of the prism?
Answers
x = 12
V = 2(12^3) + 6(12^2)
V = 2(1728) + 6(144)
V = 3456 + 864
V = 4320
The volume of the prism is 4320 cubic units
The expression for the volume is given as:
V = 2x^3 + 6x^2
When x = 12, the expression becomes
V = 2 * 12 ^3 + 6 * 12^2
Evaluate the exponent
V = 2 * 1728 + 6 * 144
Evaluate the products
V = 3456 + 864

Find the equation of a line parallel to y - 5x = 10 that passes through the point (3, 10). (answer in slope-intercept form)
Answers
y = 5x + 10
The slope-intercept form is y = mx + b, where m = slope, and b = y-intercept.
In this case, the 5 is the slope.
Parallel lines have equal slopes, so the line we need to find also has a slope of 5. Its equation is
y = 5x + b
We need to find what b is.
We can use the given point, (3, 10), in for x and y and solve for b.
10 = 5 * 3 + b
10 = 15 + b
-5 = b
