Point H is the circumcenter of triangle JKL.
Which must be true?
O FH ≈ DH
O JF ≈ JD
O JH ≈ LH
O KF ≈ LD
If H is the circumcenter of triangle JKL then true statement is JH ≈ LH.
What is Property of Circumcenter?The circumcenter of a triangle is the point of intersection of the perpendicular bisectors of the triangle's sides. It is the center of the circumcircle, which is the circle passing through all three vertices of the triangle.
The circumcenter is equidistant from the three vertices of the triangle.
This means that the distance from the circumcenter to each vertex is the same.
i.e., the distance of point H is equal from J, K and L.
Then, the length of each of is equal which is
JH = KH = LH

Fred and Wilma are in the 33% tax bracket. Their joint taxable income is $205,375. If the first $16,050 is taxed at 10%, with the remainder at 33%, how much tax will they owe?
Answer:
$64,082.25
Step-by-step explanation:
$205,375-16,050=189,325
189,325×33% (or .30)=62,477.25
16,050×10% (or .10)=1,605
1,605+62,477.25=$64,082.25
Classify the triangle.
Answer:
This looks like an acute triangle
Step-by-step explanation:
This looks like an actue triangle because all of the sides look less than 90 degrees
Also you can use prossess of elemination:
It is not a right triangle because it does not have a 90 degree angle
it is not a obtude triangle because the angles do not look grather than 90 drgress
and this is not an equlateral triangle because the angles and not all the same.
So this leave acute triangle

7 cm
2 cm
O 61.7 cm
O 110.7 cm
0 87.9 cm
O 114 cm?
Answer:
Volume of the cylinder is 87.9 cm³Step-by-step explanation:
Given that Radius of the cylinder is 2 cm and height is 7 cm. To find Volume of the Cylinder we will substitute the value of height and radius in given formula:
[tex] \\ \: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume_{(Cylinder)} = \pi r^2h}}}}}} \\ \\ [/tex]
Substituting the required values:
[tex] \\ \: \: \dashrightarrow \sf \: \: Volume = 3.14 \times {(2)}^{2} \times 7 \\ \\ [/tex]
[tex]\: \: \dashrightarrow \sf \: \: Volume = 3.14 \times 4 \times 7 \\ \\ [/tex]
[tex]\: \: \dashrightarrow \sf \: \: Volume = 3.14 \times 28 \\ \\ [/tex]
[tex]\: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume = 87.9 \: {cm}^{3}}}}}}} \\ \\ [/tex]
Hence,
Volume of the cylinder is 87.9 cm³Step-by-step explanation:
Given :-
Height of cylinder :- 7cmBase diameter of cylinder :- 2cm , radius :- 1cmTo find :-

Is 2/3 < 5/8? Help me with this
Answer:
No its 2/3 > 5/8
Step-by-step explanation:
To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as:
2/3 = 0.667
5/8 = 0.625
Then, we compare the two decimal numbers to get the answer.
0.667 is greater than 0.625. So 2/3 > 5/8
Answer:
No, 2/3 is bigger than 5/8
Step-by-step explanation:
If you convert 2/3 into a deciamal it is 0.666
and if you convert 5/8 into a decimal it is 0.625
therefore 2/3 is the bigger fraction and the statement is not correct.

How many solutions exist for the given equation? 12x 1 = 3(4x 1) – 2 zero one two infinitely many
An equation is formed of two equal expressions. The given equation 12x+1=3(4x+1)-2 has infinite numbers of solutions.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To find the solution to the equation we need to solve the given equatiopn. Therefore, the equation can be written as,
[tex]12x+1=3(4x+1)-2\\12x+1=12x+3-2\\12x+1=12x+1[/tex]
As we can see that both sides of the equation are similar to each other, therefore, for any value of x the equation will be satisfied.
Thus, the given equation 12x+1=3(4x+1)-2 has infinite numbers of solutions.

A crate weighing 500 pounds was delivered to the gym & set on the floor. To
move it, we need to get a set of dolly wheels under the edge. If we use a 15 foot
pry bar to lift the edge and place a 12 high fulcrum back 2 feet from the box,
how much downward force will need to be applied to the bar to raise the crate?
The downward force that will be needed to be applied to the bar to raise the crate is 389.65N.
How to calculate the force?From the information given, we'll first need to find the length of BC. This will be:
BC = 15 - (✓2 + ✓1)
BC = 15 - ✓5
The weight of the box will be:
= mg = 500 × 32.174 = 16087.05ft/s²
The force will then be:
= (16087.05 × ✓5)/(15 - ✓5)
= 389.65N

[tex] \frac{ \cos(x) + \sin(x) }{ \cos(x ) - \sin(x) } = \tan(45 + x) [/tex]
Answer:
First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...[tex]\frac{tan~x+1}{tan~x-1}[/tex]
Include 45 as one of the parameters and correlate with tan.[tex]\frac{tan~x+tan~45}{tan~x-tan~45}[/tex]
Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.Lastly, simplify, and you have the answer as tan(45 + x)What are the zeros of the quadratic function f(x) = 6x2 – 24x 1?
The zeros or roots of the quadratic function f(x) = 6x² – 24x +1 were found with the help of the formula.
The given quadratic equation is:
[tex]6x^{2} -24x+1=0[/tex]
What is a quadratic equation?Any equation of the form [tex]ax^{2} +bx+c=0[/tex] where a≠0 is called a quadratic equation.
We know the solution of a quadratic equation [tex]ax^{2} +bx+c=0[/tex] is given by:
[tex]x=\frac{-b +\sqrt{b^{2}-4ac } }{2a}[/tex]
[tex]x=\frac{-b -\sqrt{b^{2}-4ac } }{2a}[/tex]
So, the solution of the quadratic equation [tex]6x^{2} -24x+1=0[/tex] will be:
[tex]x=\frac{-(-24) +\sqrt{(-24)^{2}-4(6)(1) } }{2*6}[/tex]
[tex]x=\frac{12+\sqrt{138} }{6}[/tex]
[tex]x=\frac{12-\sqrt{138} }{6}[/tex]
