Step-by-step explanation: 9/7 you had to make a whole then make the fraction 2/7. 7/9 you literally just had to subtract 8-1 to gt 7 and because the denominator didn't need to change it so that makes it 7/9.

Given: ΔABC, AB=12, m∠A=60°,m∠C=45°, AB =8 Find the perimeter of ΔABC
Answers
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
\(\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}\)
∴ \(\frac{SinA}{a} = \frac{SinC}{c}\)
In the diagram, \(a = /BC/\) and \(c = /AB/ = 12\)
m∠A=60° and m∠C=45°
∴ \(\frac{Sin60}{/BC/} = \frac{Sin45}{12}\)
\(/BC/ = \frac{12 \times Sin60}{Sin45}\)
\(/BC/ = 6\sqrt{6}\)
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
\(\frac{SinB}{b} = \frac{SinC}{c}\)
From the diagram, \(b = /AC/\)
\(\frac{Sin75}{/AC/} = \frac{Sin45}{12}\)
\(/AC/ = \frac{12 \times Sin75}{Sin45}\)
\(/AC/ = 6 + 6\sqrt{3}\)
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
= \(12 + 6\sqrt{6} + 6+6\sqrt{3}\)
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
Answer:
Using the figure above, if AB = RT and ∠R = 70°, then ________.
ΔABC ~ ΔRTS
m ∠ S = 50°
ΔABC ≅ ΔRTS
m ∠ S = 60°

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0
Answers
Answer:
Step-by-step explanation:
254
Answer: We are given that the area of the rectangular room is 750 square feet, and the width of the room is 5 feet less than the length of the room.
Let's use y to represent the length of the room in feet. Then, the width of the room would be y - 5.
The area of a rectangle is given by the product of its length and width. Therefore, we can set up an equation:
y(y - 5) = 750
Expanding the left-hand side, we get:
y^2 - 5y = 750
This is one equation that can be used to solve for y.
Another option is to rearrange the previous equation to get:
y^2 - 5y - 750 = 0
This is a quadratic equation that can be solved using the quadratic formula or factoring.
A third option is to use the equation:
(y + 25)(y - 30) = 0
This equation can be obtained by factoring the previous quadratic equation. The solutions to this equation are y = -25 and y = 30, but since the length of the room cannot be negative, the only valid solution is y = 30.
Therefore, the three equations that can be used to solve for y are:
y(y - 5) = 750
y^2 - 5y - 750 = 0
(y + 25)(y - 30) = 0

In the game of roulette, a player can place a $6 bet on the number 10 and have a 1/38 probability of winning. If the metal ball lands on 10, the player gets to keep the $6 paid to play the game and the player is awarded an additional $210. Otherwise, the player is awarded nothing and the casino takes the player's $6.
(a) What is the expected value of the game to the player? (Round to the nearest cent as needed.)
(b) If you played the game 1000 times, how much would you expect to lose?
Note that the expected value is the amount, on average, one would expect to gain or lose each game. (Round to the nearest cent as needed.)
Answers
The expected value of the game to the player is $5.95, and if they play 1000 times, they would expect to lose $5950.
The expected value of the game to the player is the average amount of money they can expect to win or lose in the long run. To calculate the expected value, we must multiply the probability of winning (1/38) by the amount of money won ($210) and subtract the probability of losing (37/38) by the amount of money paid to play ($6). This gives us an expected value of (1/38) x ($210) - (37/38) x ($6) = $5.95. If you played the game 1000 times, you would expect to lose $5950 in total, as the expected value of each game is -$5.95. This means that, on average, you would lose $5.95 for every game you play. Multiplying this amount by 1000 gives us our expected total loss of $5950.
The calculation for the expected value of the game and the total expected loss for playing it 1000 times is as follows:
Expected value = (1/38) x ($210) - (37/38) x ($6)
= ($5.526) - ($5.684)
= -$0.158
Therefore, the expected value of each game is -$0.158, which means that on average, a player can expect to lose $0.158 for every game played.
Total expected loss for playing 1000 times = (-$0.158) x 1000
= -$158
Therefore, if the game is played 1000 times, the total expected loss is -$158

What is Polynomial function ?
A polynomial function is a type of mathematical function that consists of a sum of terms, where each term is a product of a constant coefficient and one or more variables raised to non-negative integer powers. In other words, a polynomial function is an algebraic expression that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents.
Thank you for providing the graph of the polynomial f(x). Based on the graph, we can see that the polynomial has roots at x = -2, x = -1, x = 2, and x = 7. Therefore, (x+2), (x+1), and (x-2) are factors of f(x) because they correspond to the roots of the polynomial.
However, since there is no point on the graph where f(x) is equal to zero when x = -7, we can conclude that (-x+7) is NOT a factor of f(x).
Therefore, (x+2), (x+1), and (x-2) are factors of f(x) because they correspond to the roots of the polynomial.

What is the probability that exactly one of the selected bulbs are rated 75-watt? b. What is the probability that all three of the elected bulbs have the same rating? c. What is the probability that one bulb of each type is selected? d. What is the probability that at least two of the selected bulbs are rated 75-watt?
Answers
Answer:
A) 0.2967
B) 0.0747
C) 0.2637
D)0.6933
Step-by-step explanation:
We are told the box contains four 40-watt light bulbs, five 60-watt bulbs, and six 75-watt bulbs.
Thus, total number of bulbs = 4 + 5 + 6 = 15 bulbs
This is a combination problem.
Thus;
A) probability that exactly one of the selected bulbs are rated 75-watt will be = ((6C2) × (9C1))/(15C3)
= (15 × 9)/455
= 0.2967
B) probability that all three of the elected bulbs have the same rating;
Number of ways to select three 40 watt bulbs out of the 4 in the box = 4C1 = 4!/(3! × 1!) = 4
Number of ways to select three 60 watt bulbs out of the 5 in the box = 5C1 =
5!/(3! × 2!) = 10
Number of ways to select 75 watt bulbs out of the 6 in the box = 6C1 = 6!/(3! × 3!) = 20
Total number of ways = 4 + 10 + 20 = 34.
Thus, probability that all three of the elected bulbs have the same rating = 34/15C3 = 34/455
= 0.0747
C) probability that one bulb of each type is selected =
[(4C1) × (5C1) × (6C1)]/(15C3)
= (4 × 5 × 6)/455
= 0.2637
D) probability that at least two of the selected bulbs are rated 75-watt =
[(4C1 × 5C1 × 6C2)/15C3] + 6C3/15C3
= (4 × 5 × 15/455) + 20/455
= 0.6493 + 0.044
= 0.6933
Melody picks a number. She triples the number, squares the result, divides the square by 2, subtracts 30 from the quotient, and gets 42. What are the possible numbers that Melody could have picked?
Answers
The possible numbers that Melody could have picked are -4 and 4.
The operation that prevents us from knowing with 100% certainty the number Melody had picked is multiplication which is implied by the phrase "double the number".
Given, Let x be the number Melody had chosen.
Thus, tripling the number will give 3x, and
squaring this will result to (3x)² which is equals to 9x².
Dividing the square of the number by 2 and subtracting 30 from its quotient will give 42:
9x²/2 ₋ 30 = 42
9x²/2 = 42 ₊ 30
9x²/2 = 72
9x² = 72 × 2
9x² = 144
x² = 144/9
x² = 16
x = ±√16
x = ±4
x = ₊4 or x = 4
hence melody could have picked ₊4 or ₋4 numbers.
