Determine if the two figures below are congruent. Use the drop-down menus below to justify why. Which point on Figure 2 corresponds to point CC on Figure 1?
From the figure, we observe that,
Non-rigid motions are used to map figure 1 onto figure 2.
Here, resizing (stretching horizontally, vertically, or both ways) is a non-rigid transformation.
So, the answer is,
The figures are congruent because non-rigid motions are used to map figure 1 onto figure 2.
The point corresponding to point C is H.

The measure of the supplement of an angle is 14 less than 3 times the measure of the
complement. Find the measure of the complement.
The complementary angle to 38° is 52°.
What is an angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves. Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius.
Let the angle be x°
Then the compliment of the angle = (90-x)°
and supplement of the angle = (180-x)°
According to question, (180-x) + 14 = 3(90-x)
or, 180-x+14 = 270-3x
or, -x+3x = 270-194
or, 2x = 76
or, x = 76/2 = 38°
Hence, the complementary angle to 38° is = 90-38 = 52°

1. A manufacturing line can produce 15 widgets
in 2 minutes. How many widgets can the line
procuce in 30 minutes?
Answer:
225
Step-by-step explanation:
number of 2 minutes in 30 minutes
= 30 ÷ 2 = 15
each 2 minutes produces 15 widgets , then
15 ( lots of 2 minutes ) produces 15 × 15 = 225 widgets
Among 6225 cases of heart pacemaker malfunctions, 346 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3
different pacemakers randomly selected from this batch of 6225 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire
batch will be accepted? Is this procedure likely to result in the entire batch being accepted?
The probability is. This procedure is
(Round to three decimal places as needed.)
to result in the entire batch being accepted.
P ( All three are not caused by firmware ) = 8423 %
The probability that the entire batch will be accepted = 0.8423
We are told that out of the 6225 cases of heart pacemaker malfunctions, 346 were found to be caused by firmware.
Thus,
Cases not caused by firmware = 6225 - 346 = 5879
So, the probability of the first case not being affected by the firmware is;
P( first case not caused by firmware ) = 5879/6225
Also,
The probability of the second case not being affected by the firmware is given as;
P(second case not caused by firmware|first case not affected by firmware) = 5878/6224
Similarly,
The probability of the third case not being affected by the firmware is given as;
P(third case not caused by firmware | first and second not caused by firmware) = 5877/6223
Now that we have the three probabilities, it is clear that the occurrences are not independent because the likelihood of one event depends on the likelihood of the others.
Thus, we will make use of the general multiplication rule which is;
P(A & B) = P(B) × P(A|B)
Thus;
P( All three not caused by firmware ) = P(first case not caused by firmware ) × P( second case not caused by firmware | first case not affected by firmware) × P( third case not caused by firmware | first and second not caused by firmware)
Substituting the values,
P(All three not caused by firmware) = ( 5879/6225 ) × ( 5878/6224 ) × ( 5877/6223 )
P(All three are not caused by firmware) = 0.84232558432 = 84.23 %

Titanium is used in aerospace (jet engines, missiles, and spacecraft), military, industrial processes (chemicals and petrochemicals, desalination plants, pulp, and paper), automotive, agriculture (farming), medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, cell phones, and other applications, titanium can be alloyed with iron, aluminum, vanadium, and molybdenum, among other elements. And it's half life as per question is [tex]A(t)=A(500)*0.5^{\frac{t}{6} }[/tex]
What is titanium?The chemical element titanium has atomic number 22 and the symbol Ti. A transition metal with a silver hue, low density, and high strength that is resistant to corrosion in sea water, aqua regia, and chlorine can be created by reducing the only form it is found in the nature—an oxide.
William Gregor found the titanium in Cornwall, Great Britain, in 1791. Martin Heinrich Klaproth gave the metal the Titans' name from Greek mythology. The element is found in practically all living organisms, as well as bodies of water, rocks, and soils. It is mostly found in the minerals rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere. The Kroll and Hunter procedures are used to separate the metal from its main mineral ores. Titanium dioxide, the most prevalent substance, is a well-liked photocatalyst and is utilized in the production of white pigments. In addition, there are other substances such titanium tetrachloride (TiCl4), which is used in smoke screens and catalysts, and titanium trichloride (TiCl3), which is a catalyst in the creation of polypropylene.
This equation can be used to calculate the quantity of unstable nuclei left after time t:
[tex]N(t)=N(0)*0.5^{\frac{t}{T} }[/tex]

Henry is younger than Cameron. Their ages are consecutive odd integers. Find Henry's age if the sum of Henry's age and 2 times Cameron's age is 85.
Since we used x and x+2 as consecutive odd integers. "x" to represent Henry's age, Henry's age is 27. Since we used the expression "x+2" to represent Cameron's age, Cameron's age is "27+2" which is just 29.
How to do age sums?So the consecutive odd integers, just means they're separated by a value of 2. This can be generally expressed as "a and a+2" where the these two values would be consecutive odd integers assuming "a" is an integer.
So let's express the Henry's age as the variable "x", since it's unknown. Since Cameron is older, and by definition of a consecutive odd integer, Cameron's can be expressed as "x+2"
So the equation we need to set up is 2(Cameron's age) + (Henry's age) = 85
So we can substitute variables we defined to express Cameron and Henry's age:
2(x+2)+x= 85
Distribute the 2:
2x+4+x
Add like terms:
3x+4=85
Subtract 4 from both sides:
[tex]3x= 81[/tex]
Divide both sides by 3:
x=27
Since we used "x" to represent Henry's age, Henry's age is 27. Since we used "x+2" to represent the Cameron's age, Cameron's age is "27+2" which is just 29.

Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseBeing "x" the number of miles driven, and knowing that:
Company A charges $20.40 monthly for up to 3 gigabytes of data and $9.80 per additional gigabyte. → Price of company A= 20.40 +9.80xCompany B charges $18.60 monthly for up to 3 gigabytes of data and $10.10 per additional gigabyte.→ Price of company B= 18.60 +10.10xIf the price charged by each company is the same, the equation is:
Price of company A= Price of company B
20.40 +9.80x= 18.60 +10.10x
