The presence of an angle bisector will result in what type of angles?
Complementary angles
Congruent angles
Vertical angles
Supplementary angles
Answer:
Congruent angles
Step-by-step explanation:
Angle bisectors, divides the given angle into two equal parts
thus if value of angle is x then angle bisector will divide this angle into parts
of equal value x/2 .
_______________________
complementary angles are two angles whose sum is 90 degrees.
since we do not the value of angle we cannot say with certainty that the angles are complementary
Congruent angles are angles who have the same angular measurement.
since, in above problem we have seen that angle bisector divides the angle in two equal parts.
hence angles are equal and thus they are congruent angle.
Congruent angles is the correct answer.
_______________________________________
vertical angles are angle opposite two one another when two line cross each other.
Since in the problem line is not intersecting each other thus, angles do not qualify to be vertical angles
Supplementary angles are two angles whose sum is 180 degrees.
since we do not the value of angle we cannot say with certainty that the angles are Supplementary.
Hence correct option is Congruent angles
Answer:
congruent angles

Step-by-step explanation:
or 130. let me know if I'm wrong
If the measure of arc AB is 50°, then the measure of its inscribed angle ACB is, 130°
What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
The measure of arc AB = 50°
The measure of its inscribed angle ACB = ?
Here, ACBP will make a quadrilateral
And, the sum of opposite angles of quadrilateral is 180°
So, ∠ACB + ∠AB = 180°
⇒ ∠ACB = 180° - 50°
⇒ ∠ACB = 130°
Hence, the measure is 130°

A rectangular garden has a length of x + 2 ft. and a width of x + 8 ft. What must x be in order for the garden to have an area of 91 sq. ft.?
Answer:
x=5
Step-by-step explanation:
5+2=7
5+8=13
13*7=91
Answer: 5 ft
Step-by-step explanation:
Our equation can be (x + 8)(x + 2) = 91. Now we solve:
(x + 8)(x + 2) = 91
x^2 + 2x + 8x + 16 = 91 expand
x^2 + 10x + 16 = 91 simplify
x^2 + 10x - 75 = 0 subtract 91 from both sides
(x + 15)(x - 5) = 0 factor
x + 15 = 0 x - 5 = 0
x [tex]\neq \\[/tex] -15 x = 5
x can't equal -15 because you cannot have negative feet, so x = 5 feet
Michael started a savings account with $100. After 6 weeks, he had $140, and after 12 weeks, he had $260. What is the rate of change of money in his savings account per week?
this question looks easy but nothing makes sense to me second half didn't line up with my answer
Answer:
Rate of change of money in Michael's account will be $20 per week.
Step-by-step explanation:
If we draw a graph for the duration of investment on x-axis and amount in the account on y-axis, ordered pairs for both the conditions will be,
After 6 weeks, amount in the account = $140
Ordered pair : (6, 140)
After 12 weeks, amount in the account = $260
Ordered pair : (12, 260)
Rate of change in hi account per week = [tex]\frac{\triangle y}{\triangle x}[/tex]
= [tex]\frac{260-140}{12-6}[/tex]
= [tex]\frac{120}{6}[/tex]
= $20 per week
Therefore, rate of change of money in Michael's account will be $20 per week.

WILL GIVE BRAINLIEST AND 20 POINTS! Which function is the inverse of f(x) = -5x -4?
Answer:
-1/5x -4/5 = y
Step-by-step explanation:
f(x) = -5x -4
y = -5x-4
Switch x and y
x = -5y -4
Solve for y
Add 4
x+4 = -5y
Divide by -5
-1/5x - 4/5 = -5y/-5
-1/5x -4/5 = y
Answer:
f(x) = -5x - 4
let f(x)= y
y = -5x -4
x = -5y - 4
-5y = x+4
y = - (x +4)/5
The inverse of f(x) is -(x +4)/5

A)
You take the four Aces, four 2's, and four 3's from a standard deck of 52 cards, forming a set of 12 cards. You then deal all 12 cards at random to four players, so that each player gets three cards. What is the probability that each player gets an Ace, a 2, and a 3?
B)
In the SuperLottery, three balls are drawn (at random) from ten white balls numbered from 1 to 10, and one SuperBall is drawn (at random) from ten red balls numbered from 11 to 20. When you buy a ticket, you choose three numbers from 1 to 10, and one number from 11 to 20.
Answer:
A) The probability that each player gets an ace, a 2 and a 3 with the order unimportant = (72/1925) = 0.0374
B) The probability of winning the jackpot = (1/1200) = 0.0008333
Step-by-step explanation:
A) There are four Aces, four 2's, and four 3's, forming a set of 12 cards
These cards are to be divided at random between 4 players.
What is the probability that each player gets an ace, a 2 and a 3.
We start with the first player, the probability of these cards for the first player, with order not important (because order isn't important, there are 6 different arrangement of the 3 cards)
6 × (4/12) × (4/11) × (4/10) = (16/55)
Then the second player getting that same order of cards
6 × (3/9) × (3/8) × (3/7) = (9/28)
Third player
6 × (2/6) × (2/5) × (2/4) = (2/5)
Fourth player
6 × (1/3) × (1/2) × (1/1) = 1
Probability that each of the players get different cards is then a multiple of the probabilities obtained above
= (16/55) × (9/28) × (2/5) × 1
= (288/7700) = (72/1925) = 0.0374
B) The concluding part of the B question.
To win the jackpot, the numbers on your ticket must match the three white balls and the SuperBall. (You don't need to match the white balls in order). If you buy a ticket, what is your probability of winning the jackpot?
Probability of wimning the jackpot is a product the probability of getting the 3 white balls correctly (order unimportant) and the probability of picking the right red superball
Probability of picking 3 white balls from 10
First slot, any of the 3 lucky numbers can fill this slot, (3/10)
Second slot, only 2 remaining lucky numbers can fill this slot, (2/9)
Third slot, only 1 remaining lucky number can fill this slot, (1/8)
(3/10) × (2/9) × (1/8) = (1/120)
Probability of picking the right red superball
(1/10)
Probability of winning the jackpot = (1/120) × (1/10) = (1/120) × (1/10) = (1/1200) = 0.0008333

algebra applications: find the value of x and y
Answer:
[tex]x = 14\\y = 20 \\[/tex]
Step-by-step explanation:
Finding x:
8x + 3x + 26 = 180 (Angle on a straight line add up to 180°)
11x = 180-26
11x = 154
Dividing both sides by 11
x = 14
Finding y:
3x + 5y + 38 = 180 (Angle on a straight line add up to 180°)
3(14) + 5y + 38 = 180
42 + 38 + 5y = 180
80 + 5y = 180
5y = 180-80
5y = 100
Dividing both sides by 5
y = 20
Answer:
x = 14, y = 20
Step-by-step explanation:
[tex](8x + 26) \degree + 3x \degree = 180 \degree..(straight \: line \: \angle s) \\ (11x + 26) \degree = 180 \degree \\ 11x + 26 = 180 \\ 11x = 180 - 26 \\ 11x = 154 \\ \\ x = \frac{154}{11} \\ \\ \huge \red { \boxed{x = 14}} \\ \\ (5y + 38) \degree = (8x + 26) \degree..(vertical \: \angle s) \\ 5y + 38 = 8 \times 14 + 26 \\ 5y + 38 = 112 + 26 \\ 5y + 38 = 138 \\ 5y = 138 - 38 \\ 5y = 100 \\ \\ y = \frac{100}{5} \\ \\ \huge \purple{ \boxed{ y = 20}}[/tex]

teenagers steadily decreases
Answer:
Option (1)
Step-by-step explanation:
Characteristics of the graph attached,
1). Heart rates of the teenagers (0 to 20 years) varies from 112 beats per minute to 72 beats per minute.
2). Heart rates of the adults (20 years to 50 years) remains constant (72 beats per minute)
Option 1). Since average resting heart rate of the teenagers decreases from 0 to 10 years, so at the 20 years of age heart rate will be less than a teenager of 20 years.
Therefore, statement is not supported by the graph.
Option (2). A 20-year-old has the same average resting heart as at 30-year-old. [True]
Therefore, this option is supported by the graph.
Option (3). A 40-year-old may have the same average resting heart rate for 10 years.
[True]
Therefore, this statement is supported by the graph.
Option (4). The average resting heart rate for teenagers steadily decreases.
[True]. There is a linear decrease in the teenagers heart rate shown in the graph.
Therefore, the given statement is true and supported by the graph.
Option (1) will be the answer.

Answer:
x = 27
Step-by-step explanation:
4(x−9)=4(9+1/3x).
Divide each side by 4
(x−9)=(9+1/3x)
Subtract 1/3 x from each side
x - 1/3x -9 = 9+1/3x -1/3x
2/3x -9 = 9
Add 9 to each side
2/3x -9+9 = 9+9
2/3x = 18
Multiply each side by 3/2
3/2 * 2/3x = 18*3/2
