Step-by-step explanation:
The segment AC is the angle bisector of angle BAD and angle BCD.
What is an angle bisector?A ray, segment, or line that divides a given angle into two equal angles is known as an angle bisector.
When something is bisected or bisected, it is split into two equal sections. In geometry, an angle bisector is a line or ray that divides a triangle into two equal angles.
here, we have,
Given that ΔABC ≅ ΔADC Prove: AC bisects ∠BAD and AC bisects ∠BCD
From the given data it is concluded that all the corresponding angles of the triangle are equal to each other.
In the triangle ABC and ADC:-
∠BAC = ∠DAC
∠BCA = ∠DCA
From the above proof, it is concluded that the AC bisects ∠BAD and ∠BCD.
Therefore, the segment AC is the angle bisector of angle BAD and angle BCD.

Use f(x)=3x/x+1 and g(x)=-2/x+1 to find the following
Answer:
a) 3x-2/x+1
b)14/5 as an improper fraction or 2 and 4/5 as a mixed number
Step-by-step explanation:
a) You just have to add f(x) and g(x) together and since the denominator is the same you can just add the numerators which gives you 3x-2/x+1
b)You have to plug in 4 to every x value in both functions so you get 3(4)/4+1 for f(x) and -2/4+1 for g(x) this simplifies down to 12/5 and -2/5 you then have to subtract those two fractions as stated in part b which gives you 14/5 as an improper fraction or 2 and 4/5 as a mixed number

The zoom feature on a camera lens allows you to dilate what appears on the display. When you change from 100% to 600%, the new image on your screen in an enlargement of the original image with a scale factor of 5. If the new image is 36 millimeters wide, what was the width of the original image?
A: 6 mm
B: 2mm
C: 12 mm
D:5 mm
Answer:6mm
Step-by-step explanation:
So we know that you started with 100% and ended with 600% to get from 100 to 600 you would need to multiply by 6
100 * 6 = 600
So you know that to get back to your original number you would need to divide by 6
If you are trying to figure out what the original width is you would divide your current number by 6 to get the original number
36 / 6 = 6
A cheese can be classified as either raw-milk or pasteurized. 82% of cheeses are classified as pasteurized.
a. Two cheeses are chosen at random. What is the probability that both cheeses are pasteurized?
b. Four cheeses are chosen at random. What is the probability that all four cheeses are pasteurized?
c. What is the probability that at least one of four randomly selected cheeses is raw-milk? Would it be unusual that at least one of four randomly selected cheeses is raw-milk?
Answer:
Step-by-step explanation:
A cheese is said to be classified as either raw-milk or pasteurized.
Given that: 82% is pasteurized,
Then:
Supposed two cheeses are chosen at random;
P(both cheeses are pasteurized) = 0.82 × 0.82
= 0.6724
If four cheeses are chosen at random;
P(that all four cheeses are pasteurized) = 0.82 × 0.82 × 0.82 × 0.82
P(that all four cheeses are pasteurized) = 0.452
The required probability for at least one of the four randomly selected cheeses is raw milk is:
P(at least one of the randomly selected cheese is raw milk) = 1 - P(that all four cheeses are pasteurized)
P(at least one of the randomly selected cheese is raw milk) = 1 - 0.452
P(at least one of the randomly selected cheese is raw milk) = 0.548
However, since the probability that at least one of the randomly selected cheese is raw milk is greater than one; then we can conclude that;
It is not unusual that at least one of four randomly selected cheeses is raw-milk.

Answer:
[tex]a_n=11-10\,n[/tex]
Step-by-step explanation:
Notice that in the sequence :
1, -9, -19, ... one term differs from the following by a constant number that is subtracted from the first one. There is what is called a "common difference" (d = -10)
the first term is "1", and we can apply the formula for the nth term of an arithmetic sequence for which we know the first term , and the common difference:
[tex]a_n=a_1+(n-1) * d\\a_n=1\,+\,(n-1)*(-10)\\a_n=1-10\,n+\,10\\a_n=11-10\,n[/tex]
Suppose you play a coin toss game in which you win $1 if a head appears and lose $1 if a tail appears. In the first 100 coin tosses, heads comes up 42 times and tails comes up 58 times.
Answer:
Percentage of heads = 42 %
Net loss = $16
Step-by-step explanation:
Given:
Total number of tosses = 100
Number of heads come = 42
Number of tails come = 58
Find:
Percentage of heads
Net loss
Computation:
Percentage of heads = Number of heads come / Total number of tosses
Percentage of heads = 42 / 100
Percentage of heads = 42 %
Net loss = 58(1) - 42(1)
Net loss = $16
#8 Mina buys a phone case on sale. If the phone case usually costs $34.99, and it was on sale for 18% off, how much did Mina pay? Round to the nearest cent. *
Answer:
28.6918 or 28.69
Step-by-step explanation:
Answer:
$28.69
Step-by-step explanation:
First, let's find how much 18% of $34.99 is. We can do this in one step by multiplying 34.99 by .18.
[tex]34.99*.18=6.30[/tex]
Now, just subtract the sale from the original cost.
[tex]34.99-6.30=28.69[/tex]
Mina paid $28.69.

Which best describes how to solve the equation for x.
x/c = d
A. Multiply both sides by d.
B. Multiply both sides by c.
C. Divide both sides by d.
D. Divide both sides by c.
Answer:
B. multiply both sides by c.
Step-by-step explanation:
To solve the equation for x, you have to isolate the x variable on one side of the equation. To do this, do the opposite of any operation applied to x to remove other variables from the x's side of the equation:
x/c = d
multiply both sides of the equation by c to isolate x:
(x/c) * c = d * c
x = dc
Now x can be solved for.

Find the area of a square with side length x when x is equal to the given value. Is the area of a square and the length of its side directly proportional? Justify your answer.
1. x=15 ft.
2. x=10 in.
3. x=3 in
Answer:
x = 3 in
Step-by-step explanation:
Since it's a square, to find the area, all you have to do is multiply one side of the square by another. Since this is a square, all the sides are equal. so 3x3 = 9. 9 sq. in.
Based on experience, the probability that an incoming email is spam (an undesired message of solicitation) is 38%. If three emails are in my inbox, what is the probability that:A. All three messages are spam.B. At least one of the three messages are spam.C. None of the three messages are spam.
Answer:
0.0549
0.7617
0.2383
Step-by-step explanation:
Given that:
Probability that incoming email is spam ;
P(spam) = 0.38
If three emails are in my inbox, what is the probability that:
A. All three messages are spam.
P(1st message being spam) * p(second message being spam) * p(3rd message being spam)
= (0.38) * (0.38) * (0.38)
= 0.054872
= 0.0549
B. At least one of the three messages are spam.
1 - p(none of the 3 messages are spam)
P(none of the 3 messages are spam)
P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62
1 - [P(not spam) * p(not spam) * p(not spam)]
1 - (0.62 * 0.62 * 0.62)
= 1 - 0.238328
= 0.761672
= 0.7617
C. None of the three messages are spam.
P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62
P(not spam) * p(not spam) * p(not spam)
(0.62 * 0.62 * 0.62)
= 0.238328
= 0.2383

What is the Area of a Rectangle?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
Area of a rectangle = length × width.
The amount of square feet of outdoor carpet needed
= area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)
The amount of square feet of outdoor carpet needed
= 12 × 4 - (3 × 2 + 2 × 1)
= 48 - (6 + 2)
= 40 ft²
Thus, 40 ft² outdoor carpet needed.
