Part A--What is the measure of angle "a" and how do you know? Use vocabulary words to justify your answer. Show your work. Part B--What is the measure of angle "b" and how do you know? Show your work. Part C--What is the measure of angle "c" and how do you know? Show your work. Two straight lines intersect at a point to form angle a. The measure of the angle opposite to angle a is 30 degrees. Angle a is the angle of a right triangle having another angle equal to b. A triangle with one angle labeled c is on the left of the figure. The angle adjacent to c is labeled 75 degrees
The measure of angle a is 30° , angle b is 60° and angle c is 105° calculated from the properties of angles and of triangle.
When two straight lines intersect each other at some angle, say line AB intersect line CD, then the opposite angles formed by the two lines are called vertically opposite angles. A pair of vertically opposite angles are equal to each other.
Angle a is formed at the intersection of the two straight lines, say AB and CD. The angle opposite to angle is 30°.
Thus from the definition of vertically opposite angles we get,
Angle a = 30° , since pair of vertically opposite angles are equal to each other.
In a right angle triangle one of three angles is 90° and the other two angles are acute angles. The sum of all the angles of a triangle is 180°.
Say ΔMNO is a right angle triangle where angle a is one of the other two acute angles (where angle a = 30°).
The third angle (acute) is b.
Thus from the sum of triangle we get,
Angle a + Angle b + 90° = 180°
⇒ 30° + Angle b + 90° = 180°
⇒ Angle b = 60°
Here angle c is an angle labelled in a triangle (on the left of the previous triangle, say ΔMNO).
Two angles are said to be adjacent angles when they have a common vertex and side. The pair of adjacent angles sum to 180° , that is they are supplementary angles.
The adjacent angle of Angle c is 75°.
Thus, Angle c + 75° = 180°
⇒ Angle c = 105°

Calvin has a gift card which he is using to buy candy (x), and he has been tracking how much money (y) he spends. He noted that after buying 4 pieces of candy (in all) he has $28.00 left on his card and then after buying 10 pieces of candy (in all) he has $25.00 left on his card. Write the equation of the line that represents his spending on candy
Answer:
To write the equation of the line that represents Calvin’s spending on candy, we need to first find the slope and the y-intercept of the line.
We can use the two points given in the problem: (4, 28) and (10, 25)
Slope (m) = (y2 - y1) / (x2 - x1)
= (25 - 28) / (10 - 4)
= -3/6
= -1/2
The slope represents the rate at which Calvin is spending money on candy.
Now, we can use the point-slope form of the equation of a line to find the equation of the line.
y - y1 = m(x - x1)
y - 28 = (-1/2)(x - 4)
y - 28 = (-1/2)x + 2
y = (-1/2)x + 30
Therefore, the equation of the line that represents Calvin’s spending on candy is y = (-1/2)x + 30.
Answer: Equation that represents his spending on candy- y = (³⁄₁₀) x
X = number of candy
Step-by-step explanation:
y = money spend x = number of candy
y = (m)x
cost for 10 pieces of candy = $(28 - 25) = $3
⇛ 3 = (m)x10 (x = 10 & y = 3)
⇛m=(³⁄₁₀)
Therefore the equation representing his spending on candy is
⇛ y = (³⁄₁₀) x

According to the U. S. Bureau of the Census, in 2000 there were 35. 3 million residents of Hispanic origin living in the United States. By 2010, the number had increased to 50. 5 million. The exponential growth function A = 35. 3ekt describes the U. S. Hispanic population, A, in millions, t years after 2000. A. Find k, correct to three decimals places. B. Use the resulting model to project the Hispanic resident in population in 2015. C. In which year will the Hispanic resident population reach 70 million?
The value of k is approximately 0.034. The projected Hispanic resident population in 2015 is approximately 73.9 million. The Hispanic resident population will reach 70 million in approximately 24.7 years after 2000, which corresponds to the year 2024.
To find k, we can use the fact that A = 35.3 million when t = 0 (i.e., in 2000), and A = 50.5 million when t = 10 (i.e., in 2010). Substituting these values into the exponential growth function, we get
35.3 = 35.3e^0k
50.5 = 35.3e^(10k)
Dividing the second equation by the first equation, we get
50.5/35.3 = e^(10k)
Taking the natural logarithm of both sides, we get
ln(50.5/35.3) = 10k
Solving for k, we get
k ≈ 0.034
Therefore, the exponential growth function is A = 35.3e^(0.034t).
To project the Hispanic resident population in 2015, we need to find A when t = 15 (i.e., 15 years after 2000). Substituting t = 15 into the exponential growth function, we get
A = 35.3e^(0.034*15) ≈ 73.9 million
Therefore, the projected Hispanic resident population in 2015 is approximately 73.9 million.
To find the year in which the Hispanic resident population reaches 70 million, we need to solve the exponential growth function for t when A = 70. Substituting A = 70 into the exponential growth function, we get
70 = 35.3e^(0.034t)
Dividing both sides by 35.3, we get
e^(0.034t) = 70/35.3
Taking the natural logarithm of both sides, we get
0.034t = ln(70/35.3)
Solving for t, we get
t ≈ 24.7
Therefore, the Hispanic resident population will reach 70 million in approximately 24.7 years after 2000, which corresponds to the year 2024.

A scale model of a tower is 24 inches. The scale is 1.5 in. : 10 ft. What is the actual height, in feet, of the tower?
The actual height of the tower is 160 feet.
Given that, a scale model of a tower is 24 inches.
The scale is 1.5 inches:10 feet.
We know that, 1 foot = 12 inches
So, the scale 1.5 inches : 120 inches.
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
1.5/120 = 24/The actual height of the tower
1.5×The actual height of the tower = 24×120
The actual height of the tower=2880/1.5

A.
|t+4|<=48
B.
|t+48|<=4
C.
|t-4|>=48
D.
|t-48|<=54
The inequality to find the number of tablespoons of flour actually used in a recipe is |t - 48| <= 4. The correct answer is D.
Since the recipe calls for 3 cups of flour with a variation of up to 4 tablespoons, the total amount of flour used can vary between 3 cups - 4 tablespoons and 3 cups + 4 tablespoons. Converting tablespoons to cups, this becomes 3 cups - 1/4 cup and 3 cups + 1/4 cup.
Thus, the range of cups of flour used is [3 - 1/4, 3 + 1/4], which is [2.75, 3.25]. Multiplying by 16 to convert back to tablespoons, we get the range [44, 52].
So, the inequality that could be used to find the number of tablespoons of flour actually used in the recipe is
|t - 48| <= 4
where t is the number of tablespoons of flour used. So, the correct option is D).

b = 11.655
b = 12.516
b = 16.841
The measure of side ‘b’ in the given triangle ABC, with angle A measuring 54 degrees and angle C measuring 59 degrees and side BC measuring 11 is option-c:12.516, which is found using Sine-law.
What is Sine-law?In a scalene or oblique triangle (a non-right triangle), the law of sine describes the relationship between the sides and angles. Trigonometric laws such as the law of sines and law of cosines are crucial when "solving a triangle" by calculating the unknown angles or sides. The ratio of a triangle's side lengths to the sine of each of its opposite angles must be equal in order for the sine rule to apply. Triangle side length ratios to their corresponding opposite angles are connected by the law of sines. All three sides and the diagonal angles maintain the same ratio.
Given that ∠A= 54° ,∠C= 59° & side BC=a=11
We know that ∠A + ∠B + ∠C = 180° {angle sum property}
Consider △ABC,
54° + 59° + ∠B = 180°
113° + ∠B = 180°
∠B = 180°- 113°
∠B = 67°
Applying Sine-Law,
[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B} = \frac{C}{sin\ C}[/tex]
By using,
[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B}[/tex] , we get:
[tex]\frac{11}{sin\ 54} =\frac{B}{sin\ 67}\\ \\\frac{11}{0.80901} =\frac{B}{0.92050} \\\\B=\frac{11}{0.80901} \times 0.92050[/tex]

How do you find the hypotenuse of a 45-45-90 triangle if you know the length of the legs?
The length of the hypotenuse of a 45-45-90 triangle is √2x units.
To find the hypotenuse of a 45-45-90 triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the longest side (hypotenuse).
Let's denote the length of each leg of the triangle as "x". Since the triangle is isosceles, both legs are of equal length. Therefore, we can write:
Leg 1 = Leg 2 = x
To find the length of the hypotenuse (which we'll call "h"), we can use the Pythagorean theorem as follows:
x² + x² = h²
Simplifying this equation, we get:
2x² = h²
To solve for h, we need to take the square root of both sides of the equation:
√(2x²) = √(h²)

To determine the sample size needed to estimate a parameter, you must know the margin of error. (True or False)
The margin of error is an important factor in determining the sample size needed to estimate a parameter, it is not the only factor - False.
Other factors that need to be considered include the level of confidence desired, the variability of the population being sampled, and the size of the population.
The margin of error is the amount of error that is acceptable in the estimate of the parameter. The smaller the margin of error desired, the larger the sample size needed.
A higher level of confidence requires a larger sample size, as there is less room for error in the estimate. The variability of the population being sampled also plays a role in determining the sample size needed.
Finally, the size of the population being sampled also affects the sample size needed.
A smaller population requires a smaller sample size, while a larger population requires a larger sample size to ensure a representative sample.
In summary, while the margin of error is an important factor in determining the sample size needed to estimate a parameter, it is not the only factor.

The length of segment a in the given chords is determined as 2.
What is the length of segment a?The measure of length a is calculated by applying the following formula.
Based on the angle of intersecting chord theorem, we will have the following equation.
a x 6 = 3 x 4
6a = 12
divide both sides of the equation by 6;
6a/6 = 12/6
a = 2
Thus, the value of a in the given chords is determined by applying chord theorem.

For Exercises 16-18, use the following information. Brian invests $200 in an
account that pays 5% annual interest compounded continuously.
16. Write a function that models the amount y in the account after x years.
17. Write the domain and range using inequalities. Explain their meaning in this context.
18. How much will Brian have in the account after 8 years?
1. The function that models the amount in the account after x years is [tex]y(x) = 200e^{0.05t}[/tex]
2. The domain is [tex]x > = 0[/tex]. The range is [tex]y > = 200[/tex]
3. After 8 years, Brian will have $298.37 in the account.
How much money will Brian have after x years?Function defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The formula for continuous compounding is [tex]A = Pe^{rt}[/tex] where the A is the amount, P is the principal, e is Euler's number, r is the annual interest rate and t is the time in years.
Data:
A = ?
P = 200
t = ?
r = 5% = 0.05
Plugging in the values, we get: [tex]A = 200e^{0.05t}[/tex]which is the function.
2. The domain of the function is x >= 0 which means the number of years must be non-negative.
The range of the function is y >= 200 since the amount in the account cannot be negative and it starts with an initial investment of $200.
3. To get amount in the account after 8 years, we will plug in x = 8 into the formula:
[tex]y = 200 * e^{0.05*8}\\y = 200 * 1.49182469764\\y = 298.364939528\\ y = $298.37.[/tex]
