Answers
Answer:
Angle C is 54 degrees
Step-by-step explanation:
Angle B is 67 degrees and Angle A is 59 degrees. You add those two together to get 126 and subtract that from 180 to get the measure of Angle C
The measure of angle C is 54°.
From the diagram given, triangle A'B'C is a reflection of triangle ABC, therefore, triangle A'B'C' is similar to triangle ABC.
This implies that:angle A = angle A' = 59°
angle B = angle B' = 67°
angle C = angle C' = ?
Therefore,angle C = 180 - (angle A + angle B) ---> Sum of angles in a triangle equals 180°.
Plug in the valuesangle C = [tex]180 - (59 + 67)\\[/tex]
angle C = 54°
Therefore, the measure of angle C is 54°.

What is Distance Formula?The distance between two points P(a, b)a nd Q(c, d) is
D = √(c- a)² + (d- b)²
Given:
Center at (-2,7) if a point on the circle has coordinates (3,-1).
Using Distance Formula
D = √( 3-(-2))² + (1-7)²
D = √ (3 +2)² + (-6)²
D = √5² + 36
D = √25+36
D = √61
D= 7.81 unit

The intensity of the sound, I watts/m², received from a loudspeaker is
inversely proportional to the square of the distance, d metres, from the
loudspeaker.
When d = 2,1 = 30
Work out the value of I when d = 10
PLEASE HELP
Answers
Answer:
The value of I for d = 10 will be 1.2 watts/m^3
Step-by-step explanation:
Let I be the intensity of sound and d be the distance
According to given statement, "The intensity of the sound, I watts/m², received from a loudspeaker is inversely proportional to the square of the distance, d meters, from the loudspeaker. "
[tex]I \propto \frac{1}{d^2}[/tex]
Removing the proportionality symbol
[tex]I = \frac{k}{d^2}[/tex]
Putting d = 2 and I = 30
[tex]30 = \frac{k}{(2)^2}\\30 = \frac{k}{4}\\k = 30*4\\k = 120[/tex]
Putting the value of k in the equation
[tex]I = \frac{120}{d^2}[/tex]
Putting d = 10
[tex]I = \frac{120}{(10)^2}\\I = \frac{120}{100}\\I = 1.2[/tex]
Hence,
The value of I for d = 10 will be 1.2 watts/m^3

It is one-half the area of a rectangle of length 4 units and width 5 units.
It is twice the area of a square of side length 5 units.
It is one-half the area of a square of side length 5 units.
Answers
Answer:
C) It is one-half the area of a rectangle of length 4 units and width 5 units.
The total area of the triangle is 10, which we get by multiplying the height (5) times the base (4), which will be 20, and then dividing by 2, which is 10!
Given this information, we can start eliminating answers.
A) It is twice the area of a rectangle of length 4 units and width 5 units. This is answer is wrong, as the area of a rectangle with a length of 4, and a width of 5, is 20. Meaning that in order for this to be true, the area of the rectangle must be 40, which it is not.
B) It is one-half the area of a rectangle of length 4 units and width 5 units.
This is answer is right, as the area of a rectangle with a length of 4, and a width of 5, is 20, and half of that would be 10, which is half of the area of the triangle!
C) It is twice the area of a square of side length 5 units.
This answer is also wrong because the area of a square with side lengths of 5 would be 25, which is not half of the area of the triangle. In order for this to be true, the area of the rectangle must be 50, which it is not.
D) It is one-half the area of a square of side length 5 units.
This answer is wrong because the area of a square with side lengths of 5, would be 25, which is not twice the the area of the triangle. In order for this to be true, the area of the rectangle must be 12.5, which it is not.

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 50.8 and 51 min.
Answers
Answer: the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Step-by-step explanation:
Given data;
lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min
hence, height = 1 / ( 52.0 - 50.0) = 1 / 2
now the probability that the class length is between 50.8 and 51 min = ?
P( 50.8 < X < 51 ) = base × height
= ( 51 - 50.8) × 1/2
= 0.2 × 0.5
= 0.1 ≈ 10%
therefore the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%

Answer:

Step-by-step explanation:
Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.
This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.
Set them equal to each other in an equation and solve for x.
6x + 12 = 8x - 8Subtract 6x from both sides.
12 = 2x - 8Add 8 to both sides.
20 = 2xDivide both sides by 2.
x = 10The value of 10 for x will make the given parallelogram a rhombus.
A bottle contains 24oz of liquid medication.If the average dose is 2/3oz. How many dose does the bottle contain
Answers
Answer:
36
Step-by-step explanation:
keep, flip, change...
24 ÷ [tex]\frac{2}{3}[/tex] would be the same as [tex]\frac{24}{1}[/tex] × [tex]\frac{3}{2}[/tex] which is equal to [tex]\frac{72}{2}[/tex] (36 if you simplify it)
The number of dose of 2/3oz of liquid medication does the bottle contain is 36.
What is the fraction number?Fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,
[tex]\dfrac{a}{b}[/tex]
Here (a) is the numerator and (b) is the denominator.
A bottle contains 24oz of liquid medication and the average dose is 2/3oz.
Let suppose the number of dose does the bottle contain is n. There is total 24oz of liquid medication in the bottol.
As the average dose is 2/3oz. Thus the number of dose in the bottle which has 24oz of liquid medication is,
[tex]n=24\div\dfrac{2}{3}\\n=24\times\dfrac{3}{2}\\n=36[/tex]
Thus, the number of dose of 2/3oz of liquid medication does the bottle contain is 36.
