The values of x is 13.42, y is 12 and z is 26.83 for right angle triangle ABC shown below.
Describe the term right angle triangle?The Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides, is a fundamental property of right triangles.
By the figure apply Pythagorean theorem in right angle ΔABC;
x² + z² = (24+6)² = 30²
x² + z² = 900 (eq. 1)
Apply Pythagorean theorem in right angle ΔAEB;
y² + 24² = z²
z² - y² = 576 (eq. 2)
Apply Pythagorean theorem in right angle ΔAEC;
y² + 6² = x²
x² - y² = 36 (eq. 3)
subtract eq. 2 and 3; then we get,
z² - x² = 540 (add this eq. with eq. 1)
2z² = 1440
z = √720 = 26.83
put in eq. 1
x² + 720 = 900
x = √180 = 13.42
put x value in eq. 3
180 - y² = 36
y = 12
Therefore, the values of x is 13.42, y is 12 and z is 26.83

Triangle ABC is similar to triangle FGH. Given the following angle measures, find the missing angle measures.
m∠A = 22 degrees
m∠B = 75 degrees
Enter your answers as numbers only.
m∠F = _____ degrees
m∠G = _____ degrees
m∠H = _____ degrees
m∠C = _____ degrees
Answers
The missing angle measures are:
m∠F = 22 degrees
m∠G = 75 degrees
m∠H = m∠C = 83 degrees
m∠C = 83 degrees
The angle measuresSince triangles ABC and FGH are similar, their corresponding angles are equal. Therefore:m∠F = m∠A = 22 degrees
m∠G = m∠B = 75 degrees
m∠H = m∠C, since they are corresponding angles, but we still need to find the measure of m∠C.
To find m∠C, we can use the fact that the sum of the angles in a triangle is always 180 degrees. So:m∠A + m∠B + m∠C = 180 degrees
Substituting the given values, we get:22 degrees + 75 degrees + m∠C = 180 degrees
Simplifying, we get:m∠C = 180 degrees - 22 degrees - 75 degrees = 83 degrees
Therefore, the missing angle measures are:
m∠F = 22 degrees
m∠G = 75 degrees
m∠H = m∠C = 83 degrees
m∠C = 83 degrees

Complete the equation of the circle that includes the points (-5,4), (3,4), and (3,0)
Answers
The equation of circle is ( x + 1 )² + ( y - 2 )² = 20
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the points on the circle be A ( -5 , 4 ) , B ( 3 , 4 ) and C ( 3 , 0 )
Now , the equation of the circle is of the form
ax + by + c = x² + y²
Substituting the values in the equation , we get
-5a + 4b + c = 41 be equation (1)
3a + 4b + c = 25 be equation (2)
3a + c = 9 be equation (3)
Subtracting equation (2) from equation (1) , we get
-8a = 16 be equation (4)
Divide by -8 on both sides of the equation , we get
a = -2
Substitute the value of a in equation (3) , we get
3 ( -2 ) + c = 9
-6 + c = 9
c = 15
Substitute the value of a and c in equation (2) , we get
-6 + 4b + 15 = 25
4b + 9 = 25
4b = 16
b = 4
So , the value of a , b and c are -2 , 4 and 15 respectively
Now , the equation of circle will be
-2x + 4y + 15 = x² + y²
On simplifying the equation , we get
x² + y² + 2x - 4y - 15 = 0
( x² + 2x + 1 ) - 20 + ( y² - 4y + 4 ) = 0
So , the equation will be
( x + 1 )² + ( y - 2 )² = 20
Hence , the equation of circle is ( x + 1 )² + ( y - 2 )² = 20

The population in a small town is increasing annually by 2.8%. What is the quarterly rate of population increase?
Answers
Answer:
To find the quarterly rate of population increase, we first need to find the annual rate of population increase in decimal form, which is 2.8% expressed as 0.028.
To find the quarterly rate, we need to divide the annual rate by 4, since there are 4 quarters in a year:
0.028 / 4 = 0.007
Therefore, the quarterly rate of population increase is 0.007 or 0.7%
While shopping after her birthday, Annie bought 2 pairs of jeans and 3 shirts and spent $127. Her twin sister Hallie bought the same items consisting of 1 pair of jeans and 4 shirts and spent $116 how much does one pair of jeans cost and how much does a shirt cost
Answers
Let's use j for the cost of one pair of jeans and s for the cost of one shirt.
From the problem, we know that:
2j + 3s = 127 (Annie's purchase)
1j + 4s = 116 (Hallie's purchase)
We can use these two equations to solve for j and s. One way to do this is to use substitution. Solving one of the equations for one of the variables and then substituting that expression into the other equation, we get:
j = 116 - 4s (from the second equation)
2(116 - 4s) + 3s = 127 (substituting into the first equation)
Simplifying and solving for s, we get:
232 - 8s + 3s = 127
-5s = -105
s = 21
Now that we know the cost of one shirt is $21, we can substitute that value back into one of the equations to solve for j:
1j + 4(21) = 116
1j + 84 = 116
1j = 32
Therefore, one pair of jeans costs $32.
So, the cost of one pair of jeans is $32 and the cost of one shirt is $21.
Answer:
The shirt costs $21
Step-by-step explanation:
2x + 3y = 127 ....eq 1
Her twin sister Hallie bought 1 pair of jeans and 4 shirts for $116.
So, x + 4y = 116 ....eq 2
Multiplying eq 2 by 2, we get :
2x + 8y = 232 ....eq 3
Subtracting eq 1 by eq 3, we get :
(2x + 8y) - (2x + 3y) = 232 - 127
5y = 105
Thus, y = 21
Putting this value of y in eq 2, we get :
x + 4(21) = 116
x = 116 - 84 = 32
Therefore, the cost of a pair of jeans = x = $32
And the cost of a shirt = $21
Meginnis corporation's relevant range of activity is 3,000 units to 7,000 units. When it produces and sells 5,000 units, its average costs per unit are as follows:.
Answers
As per the concept of average, the cost of producing 6,000 units is $79,200.
The average, also known as the mean, is a mathematical representation of a set of data. It is calculated by adding all the values in the set and dividing the result by the number of values in the set.
When it comes to calculating the total amount of direct manufacturing cost incurred when 6,000 units are produced, it is important to use the average cost per unit. To do this, we need to multiply each average cost per unit by the number of units produced.
The total direct manufacturing cost incurred can be calculated as follows:
Direct materials = $5.20 * 6,000 = $31,200
Direct labor = $3.75 * 6,000 = $22,500
Variable manufacturing overhead = $1.65 * 6,000 = $9,900
Fixed manufacturing overhead = $2.60 * 6,000 = $15,600
The total direct manufacturing cost incurred is $79,200.

Answers
Jet could fly a distance of 752 miles in 8 hours if it travels at the same rate.
What is Speed?Speed is defined as the unit rate in terms of distance travelled and the time taken to travel the distance.
Speed has only magnitude and no direction and therefore is a scalar quantity.
Given that,
a jet travels 470 miles in 5 hours.
Distance travelled = 470 miles
Time taken to travel the distance = 5 hours
Speed of the jet = 470 miles / 5 hours = 94 miles per hour
Given that jet is travelling at the same rate. So the speed is constant.
We have to find the distance travelled in 8 hours.
Let d be the distance.
Speed = Distance / Time
Distance = Speed × Time
d = 94 × 8
d = 752 miles
Hence the distance travelled is 752 miles in 8 hours.

Answers
Answer:
Ann will owe $15,258.23 after 6 years, assuming she makes no payments.
What is Compound Interest ?
Compound interest is a method of calculating interest on a loan or investment, where interest is earned on both the initial principal amount and on any interest that has already been earned. In other words, interest is added to the principal, and then interest is calculated on the new total amount (the principal plus the previously earned interest). This results in the interest earned growing exponentially over time.
According t o given condition :
To calculate the amount Ann will owe after 6 years, we can use the formula for compound interest:
A = P(1 + r/n)^(n*t)
where:
A = the amount Ann will owe after 6 years
P = the initial principal amount borrowed, which is $8000 in this case
r = the annual interest rate as a decimal, which is 15% or 0.15
n = the number of times interest is compounded per year, which is once annually in this case
t = the number of years, which is 6 in this case
Plugging in these values, we get:
A =
A =
A = $15,258.23
Therefore, Ann will owe $15,258.23 after 6 years, assuming she makes no payments.
