The value of x is 7 and the measure of unknown angle is 64°.
The angles of triangle are given 76°, (9x+1)° and 40°.
What is angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Now, sum of three angles of a triangle is
76°+(9x+1)°+40°= 180°
⇒ 116+9x+1 = 180
⇒ 9x + 117 = 180
⇒ 9x = 63
⇒ x = 7
So, 9x+1=64°
Therefore, the value of x is 7 and the measure of unknown angle is 64°.

hello thank you for viewing my question I seem to be stuck on this problem can you please help thank you
We have 9 boy kittens and 6 girl kittens, a total of 15 kittens.
9 cats will be selected and we have to calculate the probability that 5 boy kitttens and 4 girl kittens are chosen.
We could have modeled as a binomial experiment, but the probability of choosing a boy kitten is not constant after each selection. Then, we have to select an alternative method.
We can think of it of a combinatorial problem.
In this case, it is a combination problem, as the order of selection does not matter and each kitten is equivalent within its category.
Repetition is not allowed: a kitten selected can not be selected again.
We can start finding all the possible combinations for 9 kittens out of the total 15 kittens:
[tex]C(15,9)=\frac{15!}{9!(15-9)!}=\frac{15!}{9!6!}=5005[/tex]The probability of selecting 5 boys and 4 girls will be the relation between the outcomes where there are 5 boys and 4 girls and the total number of outcomes we have just calculated.
Then, we can now calculate how many combinations of 9 kittens have 5 boys and 4 girls as a product of two combinations: the combinations for the boys C(9;5) and the combinations for the girls C(6;4).
We can calculate this as:
[tex]\begin{gathered} C(9,5)=\frac{9!}{5!4!}=126 \\ C(6,4)=\frac{6!}{4!2!}=15 \\ =>C(9,5)*C(6,4)=126*15=1890 \end{gathered}[/tex]We can now calculate the probability as the ratio of combinations 1890/5005:
[tex]p=\frac{1890}{5005}\approx0.378[/tex]Answer: the probability is 0.378.

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
So, m∠D + m∠E + m∠F = 180°
(3x + 27) + (4x + 22) + 68 = 180
7x + 49 + 68 = 180
7x = 63
x = 9
So, m∠D = (3(9) + 27)° = 54°.
The exterior angle of D = 180- 54 = 126°.
Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

What is the solution for an equation?An equation is an expression that shows the relationship between two or more numbers and variables. The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.
We have been given a linear equation as; x - 2 = 16
We need to find the value of x as the answer to the equation x - 2 = 16.
Therefore, we will eliminate the 2.

What is Weight?
The weight of an object is the force exerted on it by gravity. Some standard textbooks define weight as a vector quantity, the force of gravity acting on an object. Some define weight as a scalar quantity that is the magnitude of gravity.
Cost of the different types of the apple have been given as,
Apple A = costing $4.90 for 4 lb
Apple B = costing $1.00 for 10 oz
Apple C = costing $0.45 for 1/2 lb
For Apple A,
Since, cost of 4 lb = $4.90
Therefore, cost of 1 lb = 4.90/4
= $1.225
For Apple B,
Since, 1 oz = 0.0625 lb
Therefore, 10 oz = 0.0625 × 10
= 0.625 lb
Since, cost of 10 oz = $1.00
Therefore, cost of 0.625 lb = $1.00
And cost of 1 lb = 1/0.625
= $1.6
For Apple C,
Since, cost of 1/2 lb = $0.45
Therefore, cost of 1 lb = 0.45 × 2
= $0.90
Hence, Cost of Apple A will be the least with $1.225 per pound.

The amount paid for each is;
1) Amount earned per game = $215625 per game
2) Amount earned per minute played = $4492.1875
3) Amount earned each minute for 2/3 games = $6738.28
4) Amount earned per hour = 4492.1875 * 60 = $269531.25
How to find the rate per game?We are given;
Amount earned by athlete = $17,250,000
Number of games played = 80 Games
Number of minutes per game = 48 minutes
1) Amount earned per game = Amount earned by athlete/Number of games played = 17250000/80 = $215625 per game
2) If he played entire games for the entire minutes;
Amount earned per minute played = 17250000/(80 * 48)
Amount earned per minute played = $4492.1875
3) He played 2/3 of every game. Thus;
Amount earned each minute for 2/3 games = 17250000/((2/3) * 80 * 48)
Amount earned each minute for 2/3 games = $6738.28
4) Since amount earned for every minute is $4492.1875, then we say that;

Answer:
C(x) = 75x + 1908
Step-by-step explanation:
C(x) is the cost function.
The cost of making x bicycles is the sum of the fixed costs and the cost per bicycle.
The fixed cost is $1908.
The cost per bicycle is $75, so the per bicycle cost for x bicycles is 75x.
Add the two costs, and you get:

m(3) = 70° because 180 - 110 = 70.
A total of 240 people drove to a meeting. Of those peoplewho attended the meeting, 80% drove there. How manypeople attended the meeting?
The total number of people that drove to the meeting is 240
80% drove to the meeting
Let the total number of people who attended the meeting be x
Using the percentage and whole relationship
Part = percentage x whole
whole = x
part = 240
percentage = 80%
240 = 80/100 * x
240 = 0.8x
Divide both sides by 0.8

The angles ∠IDA, ∠YDA, and ∠RDI measures 121°, 59°, and 29.5°.
The angle ∠YDF is equal to 121°. The ∠IDA is vertically opposite angle. So, ∠ADI is equal to the ∠YDF. Hence, ∠IDA = 121°.
The angle ∠YDA and the angle ∠ADI form a linear pair. It means ∠YDA and ∠ADI are complimentary angles.
∠YDA + ∠ADI = 180°
∠YDA + 121° = 180°
∠YDA = 180° - 121°
∠YDA = 59°
The ∠FDI is vertically opposite angle to ∠YDA. So, ∠FDI is equal to the ∠YDA. Hence, ∠FDI = 59°. The ray DR bisects the ∠FDI. So, the angle ∠RDI is half of the angle ∠FDI.
∠RDI = (1/2)∠FDI
∠RDI = (1/2)59
∠RDI = 29.5°
