Find the Nonpermissible replacement for y in this expression y-7/y+9
Answers
Answer:
y cannot be -9
Step-by-step explanation:
The other word is discontinuity
It is what y cannot be
The denominator cannot be zero so
y+9 cannot be zero
y cannot be -9
Y+9/Y+7
If Y= -7
You cannot divide by 0. If Y= -7, the denominator would be 0.
Zero in the denominator is NOT allowed.
Y= -9 is the non permissible replacement for Y in this expression.

I need help with 29 , 32, 33
Answers
Answer:
29) m∠A = 83°
m∠B = 7°
32) m∠A = 103°
m∠B = 77°
33) m∠A = 24°
m∠B = 156°
Step-by-step explanation:
Question 29Complementary angles: Two angles whose measures sum to 90°.
\(\implies m \angle A + m \angle B=90^{\circ}\)
\(\implies (16x - 13)^{\circ} + (2x - 5)^{\circ}=90^{\circ}\)
\(\implies 16x - 13 + 2x - 5=90\)
\(\implies 18x -18=90\)
\(\implies 18x =108\)
\(\implies x=6\)
Substitute the found value of x into the expression for angle A:
\(\implies m \angle A = \left(16 \cdot 6 - 13 \right)^{\circ}\)
\(\implies m \angle A = \left(96 - 13 \right)^{\circ}\)
\(\implies m \angle A = 83^{\circ}\)
As the sum of angles A and B is 90°:
\(\implies m \angle B = 90^{\circ}-m \angle A\)
\(\implies m \angle B = 90^{\circ}-83^{\circ}\)
\(\implies m \angle B = 7^{\circ}\)
-------------------------------------------------------------------------------------------------
Question 32Supplementary angles: Two angles whose measures sum to 180°.
\(\implies m \angle A + m \angle B=180^{\circ}\)
\(\implies (x+11)^{\circ} + (x-15)^{\circ}=180^{\circ}\)
\(\implies x+11+ x-15=180\)
\(\implies 2x-4=180\)
\(\implies 2x=184\)
\(\implies x=92\)
Substitute the found value of x into the expression for angle A:
\(\implies m \angle A = \left(92+11 \right)^{\circ}\)
\(\implies m \angle A =103^{\circ}\)
As the sum of angles A and B is 180°:
\(\implies m \angle B = 180^{\circ}-m \angle A\)
\(\implies m \angle B = 180^{\circ}-103^{\circ}\)
\(\implies m \angle B = 77^{\circ}\)
-------------------------------------------------------------------------------------------------
Question 33Supplementary angles: Two angles whose measures sum to 180°.
\(\implies m \angle A + m \angle B=180^{\circ}\)
\(\implies (9x-12)^{\circ} + (24x+60)^{\circ}=180^{\circ}\)
\(\implies 9x-12+24x+60=180\)
\(\implies 33x+48=180\)
\(\implies 33x=132\)
\(\implies x=4\)
Substitute the found value of x into the expression for angle A:
\(\implies m \angle A = \left(9 \cdot 4-12 \right)^{\circ}\)
\(\implies m \angle A = \left(36-12 \right)^{\circ}\)
\(\implies m \angle A =24^{\circ}\)
As the sum of angles A and B is 180°:
\(\implies m \angle B = 180^{\circ}-m \angle A\)
\(\implies m \angle B = 180^{\circ}-24^{\circ}\)
\(\implies m \angle B = 156^{\circ}\)

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Answer:
B 30°
Step-by-step explanation:
come now.
the sum of all angles around one point on one side of a line is 180°.
why ?
because any line with a point can be seen as a diameter of a circle with that point as center.
and every side of the line represents then a half-circle.
and a half-circle stands for 360/2 = 180°.
so,
180 = (2x + 70) + (x - 10) = 2x + 70 + x - 10 = 3x + 60
120 = 3x
x = 40
2x + 70 = 2×40 + 70 = 80 + 70 = 150°
x - 10 = 40 - 10 = 30°
180 = Q + (2x + 70) = Q + 150
30° = Q

Roxie is a show dog her trainer wants her to have a beautiful and brilliant coat. The veterinarian suggested a special diet for the trainer to follow each feeding Roxie eats 2/3 of a can of wet dog foods 1/8 of a bag of dry food and 3/5 a patty of special meat the special meat comes in a package of 6 patties Roxie has two meals a day
Answers
Answer: the answers are below
Step-by-step explanation:
1 meal = 2/3 of a can of wet dog food, 1/8 of a bag of dry dog food, and 3/5 a patty of special meat
Food for 1 day: 2 meals = 2(2/3) = 4/3 of a can of wet dog food, 2(1/8) = 1/4 of a bag of dry dog food, and 2(3/5) = 6/5 a patty of special meat
The trainer goes to the store and buys 24 cans of wet food, 4 bags of dry food and 3 packages of meat (3*6 = 18 patties)
He has:
there is wet food for: 24/(4/3) = 24*3/4 = 18 days
there is dry food for: 4/(1/4) = 4*4 = 16 days
there is special meat food for: 18/(6/5) = 18*5/6 = 15 days
since the minimum for 15, 16 and 18 is 15 the dog will have food for 15 days and first he will run out of special meat.
1. Roxie will be fed for 15 days before the trainer needs to buy more food.
2. The trainer will run out of the special meat first, as it will last for 15 days.
3. After the special meat runs out, there will be 3 cans of wet food and 1 bag of dry food left.
4. The trainer needs to buy 96 more cans of wet food, 19 more bags of dry food, and 36 more patties of special meat to last 90 days.
5. The minimum amount of food the trainer could buy is 80 cans of wet food, 15 bags of dry food, and 72 patties of special meat, which would last for 60 meals (30 days).
Step 1: Calculate the daily consumption of each type of dog food.
Wet food: 2/3 can per meal * 2 meals per day
= 4/3 cans per day.
Dry food: 1/8 bag per meal * 2 meals per day
= 1/4 bag per day.
Special meat: 3/5 patty per meal * 2 meals per day
= 6/5 patties per day.
Step 2: Calculate the total food available for Roxie.
Wet food: 24 cans purchased.
Dry food: 4 bags purchased.
Special meat: 3 packages (3 * 6 patties = 18 patties) purchased.
Step 3: Calculate the number of days the food will last.
Days of wet food: 24 cans / (4/3 cans per day)
= 24 * 3/4
= 18 days.
Days of dry food: 4 bags / (1/4 bag per day)
= 4 * 4
= 16 days.
Days of special meat: 18 patties / (6/5 patties per day)
= 18 * 5/6
= 15 days.
Step 4: Determine which type of dog food will run out first.
The special meat will run out first, after 15 days.
Step 5: Calculate how much of the other two types of dog food will be left after the first type runs out.
After 15 days, Roxie will still have
= 18 - 15
= 3 cans of wet food left.
After 15 days, Roxie will still have
= 16 - 15
= 1 bag of dry food left.
Step 6: Plan for 90 days.
The total number of patties needed for 90 days
= (6/5 patties per day) * 90 days
= 108 patties.
and, the trainer needs to buy
= 108 / 6 = 18 packages
- For wet food, Roxie needs
= (4/3 cans per day) * 90 days
= 120 cans.
The trainer already has 24 cans, so she needs to buy
= 120 - 24 = 96 more cans.
- For dry food, Roxie needs
= (1/4 bag per day) * 90 days = 22.5 bags.
Since the trainer can't buy half a bag, she needs to round up to 23 bags.
Step 7: Minimum amount of food to buy to finish all of it after a certain number of meals.
Minimum amount of wet food to buy:
= (4/3 cans per day) * 60
= 80 cans.
Minimum amount of dry food to buy:
=(1/4 bag per day) * 60
= 15 bags.
Minimum amount of special meat to buy:
=(6/5 patties per day) * 60
= 72 patties.
Therefore, the trainer could buy a minimum of 80 cans of wet food, 15 bags of dry food, and 72 patties of special meat, and Roxie would finish all of it after 60 meals (30 days).

*PLEASE ANSWER* What is the area of minor sector AOB?
Answers
===========================================================
Explanation:
The given reflex angle is 215 degrees. A reflex angle is anything over 180 degrees, but less than 360. Subtract 215 from 360 to get the measure of angle AOB
angle AOB = 360 - 215 = 145
angle AOB = 145 degrees
We'll use this later.
Now find the area of the full circle. Use the formula A = pi*r^2. The radius is r = sqrt(10) which can be found through the distance formula or the pythagorean theorem. You want to find the length of either OA or OB to get the radius.
The area of the circle is
A = pi*r^2
A = pi*(sqrt(10))^2
A = 10pi
This is the exact area of the full circle, but we want just a fractional portion of it. Specifically we want the pie slice that is formed by angle AOB
area of sector AOB = [ (angle AOB)/360 ] * (area of full circle)
area of sector AOB = (145/360)*10pi
area of sector AOB = 145pi/36
area of sector AOB = 145*3.14/36
area of sector AOB = 12.647 approximately
area of sector AOB = 13 square units approximately, after rounding to the nearest whole number

Pls help, 20 points! A number cube is rolled d360 times, and the results are recorded as follows: 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes. What is the experimental probability of rolling a 2 or a 3?
It would help if you could put the answer in decimal form but you don't have to :D
Answers
Answer:
The experimental probability of rolling a 2 or a 3 is 2/9 or 0.222222 (go as long as you like :D)
Step-by-step explanation:
Total number of times cube roller = T = 360,
we have 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes
The probability of rolling a 2 is,
since we get 31 twos out of 360 rolls,
P(2) = 31/360
The probability of rolling a 3 is,
since we get 49 threes out of 360 rolls,
P(3) = 49/360
the experimental probability of rolling a 2 or a 3 is the sum of these two,
so,
P(2 or 3) = P(2) + P(3) = 31/360 + 49/360 = 80/360 = 2/9
P(2 or 3) = 2/9
In decimal form, P(2 or 3) = 0.2222222
The experimental probability of rolling a 2 or a 3 is 2/9 or (0.2222) .
The number of times a 2 or a 3 was rolled is the sum of the occurrences of twos and threes,
P(2) = 31
P(3) = 49
P(2) + P(3) = 31 + 49 = 80.
The total number of rolls is given as 360.
Now, calculate the experimental probability:
Experimental probability of rolling a 2 or a 3 = Number of times a 2 or a 3 was rolled / Total number of rolls
P(2 or 3) = 80 / 360
After simplifying the fraction:
Experimental probability of rolling a 2 or a 3 = 2/9
Therefore, the experimental probability of rolling a 2 or a 3 is 2/9.

Triangles ABC and DEC are similar. Side DE is 1.8 feet, side EC is 4 feet, and side BE is 0.8 foot.
Part A: Describe how to draw triangles ABC and DEC separately. Be sure to give the lengths of sides BC, DE, and EC in the description.
Part B: Find side AB. Show each step of your work.
Answers
The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively. The length of side \(AB\) is approximately \(3.36\) feet.
What is the line segment?Part A:
To draw triangles \(ABC\) and \(DEC\) separately, follow the steps below:
Draw a straight line segment DE with length \(1.8\) feet.
From point D, draw a line segment DC perpendicular to DE with length 4 feet.
Connect point E and point C with a straight line segment EC.
From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.
Draw a straight line segment BC that intersects line segment DC at point A.
Connect point A and point B with a straight line segment AB.
The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively.
Part B:
Since triangles \(ABC\) and \(DEC\) are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:
\(AB/DE = BC/EC\)
Substituting the given values, we get:
\(x/1.8 = BC/0.8\)
Solving for BC, we get:
\(BC = 0.8x/1.8\)
Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:
\(BC^2 + EC^2 = DE^2\)
Substituting the given values, we get:
\((0.8x/1.8)^2 + 4^2 = 1.8^2\)
Solving for x, we get:
\(x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8\)
\(x \approx 3.36 feet\)
Therefore, the length of side \(AB\) is approximately \(3.36\) feet.
