When a transversal cuts parallel lines, how can one angle measurement be used to determine all of the other measurements?
Answer: If two parallel lines are cut by a transversal, then corresponding angles are congruent.
Step-by-step explanation:
A rectangular piece of paper with length 25 cm and width 12 cm has two semicircles cut out of it, as shown below.
Find the area of the paper that remains. Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.
The area of the rectangular paper left after two semi circles are cut out of it is 186.96 cm².
What is a rectangle?A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°).The opposite sides of a rectangle are equal and parallel.
To caluculate the area of the paper that remains, we use the formula below.
Formula:
Ar = lb-π(b/2)²............ Equation 1Where:
Ar = Area of the paper that remainl = Length of the rectangular paperb = width of the rectangular paperr = Radius of the semi circleFrom the question,
Given:
l = 25 cmb = 12 cmr = 12/2 = 6 cmπ = 3.14Substitute these values into equation 1

Using trigonometric ratio the distance to the control tower is 750.7ft
Trigonometric RatioIn trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec(or csc), and cot in short.
The values of these trigonometric ratios can be calculated using the measure of an acute angle, θ in the right-angled triangle given below. This implies that the value of the ratio of any two sides of the triangle here depends on angle C.

A ball is dropped from a height of 10 ft and bounces 83% of its previous height on each bounce. How high off the ground is the ball at the top of the 4th bounce?
Answer:
The height of the 4th bounce would be 4.7458321; rounded would be 4.8.
Step-by-step explanation:
We can figure this question out by first converting the 83% into a decimal, by bringing back 2 decimal places:
0.83.
And then setting up this equation:
0.83 x 10 = 8.3
Now, this is for 1 bounce. We have to do this 4 more times:
0.83 x 8.3 = 6.889
3rd time:
0.83 x 6.889 = 5.71787
4th time:
0.83 x 5.71787 = 4.7458321.
Now, we can round this answer to:

tic is an isosceles triangle with a vertex angle i if the measure of i90
Applying the definition of an Isosceles triangle, given that isosceles triangle TIC has a vertex angle I of 90 degrees, the measure of angle T is 45 degrees.
In geometry, an isosceles triangle is a triangle that has at least two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. Examples of isosceles triangles include the isosceles right triangle, the golden triangle, and the faces of bipyramids and certain Catalan solids.
The two equal sides are called the legs and the third side is called the base of the triangle. The other dimensions of the triangle, such as its height, area, and perimeter, can be calculated by simple formulas from the lengths of the legs and base. Every isosceles triangle has an axis of symmetry along the perpendicular bisector of its base. The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.
An Isosceles triangle has a vertex angle and two equal base angles.
Given that triangle TIC is an isosceles triangle:
angle I is the vertex angle = 90 degrees
angle T is a base angle
angle C is also a base angle
Thus:
angle C and angle T are congruent or equal to each other.
Therefore,
Angle T = (180 - 90)/2
⇒ Angle T = 90/2
⇒ Angle T = 45 degrees.
applying the definition of an isosceles triangle, given that isosceles triangle TIC has a vertex angle I of 90 degrees, the measure of angle T is 45 degrees.

Initial population of fox = 20400
Rate of growth = 9 percent per year
These parameters can be presented as
Initial population of fox, a = 20400
Rate of growth, r = 9%
An exponential function is represented as
P(t) = a(1 + r)⁺
So, we have:
P(t) = 20400(1 + 9%)⁺
Evaluate
P(t) = 20400(1,09)⁺
The population in 2008Recall that
t = 0 in 2000
So, the value of t in 2008 is
t = 2008 - 2000
t = 8
Substitute t = 8 in P(t) = 20400(1,09)⁺

company charges $17 a month for basic service and $0.05 a minute for each long
distance call, how many minutes can be spent on long distance calls each month?
(Define a variable, create an equation, solve using algebra, and answer in a sentence.)
Answer:
160 minutes can be spent on long distance calls each month.
Step-by-step explanation:
first we know that there is standard charge of $17 for basic service, $0.05 cost per minute with a budget of $25.
let's write that into an equation to solve for (a) which will be number of minutes.
17 + a(0.05) = 25
solving:
17 + a(0.05) = 25
carry across the 17 whilst changing the sign, or some people is also thought to minus on both sides to get rid of a certain variable.
a(0.05) = 25 - 17
a(0.05) = 8
carry across the multiplication of 0.05 which will then turn into division, or divide by 0.05 on both sides to remove it.
[tex]a = \frac{8}{0.05} [/tex]
a = 160
therefore 160 minutes can be spent on long distance calls each month.

What is a Parallelogram ?
A unique variety of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
Parallelograms' characteristics
(1) The opposing sides of a parallelogram are parallel to one another. In this case, AB || CD and AC || BD
(2) A parallelogram has equal-length opposing sides. In this case, AB = CD and AC = BD
(3) In a parallelogram, the measurements of the opposing angles are equal. In this case, A Equals C and B = D.
(4) The total of all the angles of a parallelogram, like all other quadrilaterals, is 360°.
(5) A parallelogram has neighboring or contiguous angles that sum to 180 degrees. As a result, A + B, B + C, C + D, and D + A all equal 180 degrees.
(6) A parallelogram's diagonals cut each other in half. In this case, OA = OC and OB = OD
(7) The parallelogram in the figure is split into two congruent triangles by the diagonals AC and BD.
The diagonals of a parallelogram bisect each other AC = 2 CE
Substitute AC= 50 into AC = 2CE = 50 = 2CE
Calculate 50 = 2 CE=> CE = 25
The diagonals of a parallelogram bisect each other BD = 2DE
Substitute BD= 30 into BD = 2DE => 30 = 2DE
Calculate 30 = 2DE => DE = 15
Opposite sides of parallelogram are congruent AB = CD
Substitute AB = 18 into AB = CD => CD = 18
Perimeter of a triangle PΔCDE = CE + CD + DE
Substitute CE = 25, DE = 15, CD = 18.
PΔCDE = CE + CD + DE
PΔCDE = 25+ 18 + 15
