Answers
The given triangles are congruent its that ΔA B C ≅ ΔX Y Z.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
If ΔA B C ≅ ΔX Y Z then the corresponding sides will be the same.
Its that AB = XY , BC = YZ
The distance associated with two points (x₁, y₁) and (x₂, y₂) is given by
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
So,
(AB) = [tex]\sqrt {\left( {5 - 1 } \right)^2 + \left( {2 - 5 } \right)^2 }[/tex]
AB = 5
(XY) = [tex]\sqrt {\left( {-3 + 7 } \right)^2 + \left( {3 - 6 } \right)^2 }[/tex]
XY = 5
Similarly BC = YZ and CA = ZX.

Find the geometric mean between pair of numbers.
1/5 and 60
Answers
The geometric mean of 1/5 and 60 is 2√3.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Solving for the geometric mean between 1/5 and 60 using the formula:
GM = n√x1 x2 . . . xn
where n = 2, x1 = 1/5, and x2 = 60
GM = √(1/5)(60)
GM = √12
GM = 2√3
Hence, the geometric mean of 1/5 and 60 is 2√3.

Zachary purchased a computer for $1,100 on a payment plan. Two months after he purchased the computer, his balance was $870. Six months after he purchased the computer, his balance was $410. What is an equation that models the balance y after x months?
Answers
Answer:
y = 1100 - 115x
Step-by-step explanation:
Let the monthly payment be $p
In two months Zach would have paid 2p dollars
Balance would be 1100 - 2p = y
We know after 2 months, balance y was actually 870
Substituting y = 870 we get
1100 - 2p = 870
Subtract 1100 on both sides
1100 - 1100 - 2p = 870 -1100
==> -2p = - 230
Divide by -2 on both sides
-2p/-2 = -230/-2
p = 115 which represents the monthly payment .
So the balance y after m months is given by the equation
y = 1100 - 115x
We can verify by plugging in the values for the second scenario
For 6 months
y = 1100 - 115 x 6 = 1100 - 690 = $410 which agrees with the given value so our equation is consistent
The radius, diameter, or circumference of a circle is given. Find the missing measure to the nearest hundredth.

A circle is a curve sketched out by a point moving in a plane. The radius and the diameter of the circle are 5.57x cm and 11.14x cm, respectively.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that circumference of the circle is 35x cm. Therefore, the radius and the diameter of the circle can be written as,
Circumference of circle = 2 × π × (Radius of the circle)
35x cm = 2 × π × (Radius of the circle)
(Radius of the circle) = 35x/ (2 × π)
The radius of the circle = 5.57x cm
Diameter of circle = 2 × (Radius of the circle)
= 2 × 5.57x cm
= 11.14x cm
Hence, the radius and the diameter of the circle are 5.57x cm and 11.14x cm, respectively.

The sum of the measures of the angles in △ABC is 180°. The sum of the measures of angle B and angle C is twice the measure of angle A. The measure of angle B is 32° less than the measure of angle C.
Answers
Answer:
< A = 60 degrees.
< B = 44 degrees
<C = 76 degrees.
Step-by-step explanation:
A + B + C = 180 --------(1)
2A = B + C -------(2)
B = C - 32 -------(3)
We see from equation 2 that B + C = 2A so we
replace The A + B in equation (1) by 2A:
A + 2A = 180
3A = 180
A = 60.
Substitute A = 60 in equation (2):
120 = B + C
Rearranging equation (3):
32 = -B + C
Adding theses last 2 equations:
152 = 2C
C = 152/2 = 76.
Substituting for A and C in equation (1):
60 + 76 + B = 180
B = 180 - 60 - 76 = 44 degrees.

Answers
The sequence -5,15,-45,135,-405,. . . . is a geometric sequence and its 10th term is a(10) = 98,415
To determine whether a sequence is an arithmetic or geometric one, we need to check the relation between two consecutive terms.
In an arithmetic sequence, the nth term is obtained by adding the (n-1)th term with a constant, called a common difference (d).a(n) = a(n-1) + dIn a geometric sequence, the nth term is obtained by multiplying the (n-1)th term by a constant, called a common ratio (r).
a(n) = a(n-1) . r
The given sequence is:
-5,15,-45,135,-405,....
In this sequence:
a(1) = -5
a(2) = 15
a(3) = -45
and so on.
Notice that:
15 = -5 . (-3) ⇒ a(2) = a(1) . (-3)
-45 = 15 . (-3) ⇒ a(3) = a(2) . (-3)
Since the n-th term is obtained by multiplying the (n-1)-th term by a constant, r = -3, hence, the given sequence is a geometric sequence.
The formula for the nth term in a geometric sequence is given by:
a(n) = a(1) . rⁿ⁻¹
Substitute n = 10, r = -3, and a(1) = -5
a(10) = (-5) . (-3)¹⁰⁻¹

If Elon earns $45 per hour, spend $75 on dry cleaning everyday and wants to make at least $260 a day then the inequality that shows the situation is 45x-75≥260 and he atleast work for 7 and half hour each day.
Given that Elon earns $45 per hour, spend $75 on dry cleaning everyday and wants to make at least $260 a day.
We are required to write the inequality that represent the situation of Elon.
Inequality is just like an equation that shows the relationship between two variables but in greater than, less than,greater than or equal to,less than or equal to signs.
Suppose the number of hours that Elon works be x hours each day.
The earning of Elon will be 45x.
Since the expenditure is $75,the saving will be 45x-75 and if he wants to make $260 a day, the inequality will be 45x-75≥260.
45x≥260+75
45x≥335
x≥335/45
x≥7.55
Hence if Elon earns $45 per hour, spend $75 on dry cleaning everyday and wants to make at least $260 a day then the inequality that shows the situation is 45x-75≥260 and he atleast work for 7 and half hour each day.

G is between points E and H
F is the midpoint of EG
The length of EH = 14 units
The length of FG = 3 units
We have to find the length of GH.
Here,
EH = EG + GH
Length of EG = FG + EF
F is the mid point of E and G. So, EF = FG ⇒ 3 units
Now,
EG = FG + EF
EG = 3 + 3
EG = 6 units

Step-by-step explanation:
Since m∠KQF = 90°, it's a complementary angle and is equal to 90°
Step 1: Write the equation. Since The whole angle equals 90° add everything together to equal 90°
(3x - 23)° + (2/3x + 3)° = 90
3x - 23 + (2/3)x + 3 = 90
Combine like terms
multiply the denominator by 3. (3 × 3) = 9 + 2 = 11
(11/3)x - 20 = 90
+ 20 +20
(11/3)x = 110

x = 30°
Step 2: Find m∠FQR

Answer:
Mean: 160
Median: 150
Mode: none
Range: 105
Standard deviation: 35.3
Step-by-step explanation:
Given:
Mean = 320Median = 300Mode = noneRange = 210Standard deviation = 70.6If each value in the data set is multiplied by a constant value, the mean, median, mode, range, and standard deviation will all be scaled by the same amount.
Therefore, if each value in the data set is multiplied by 0.5:
Mean: 320 × 0.5 = 160Median: 300 × 0.5 = 150Mode: none × 0.5 = noneRange: 210 × 0.5 = 105Standard deviation: 70.6 × 0.5 = 35.3Proof
Data set: {1, 2, 3, 4, 5}
[tex]\sf Mean\:\mu =\dfrac{\sum x_i}{n}= \dfrac{1+2+3+4+5}{5} = 3[/tex]
[tex]\sf Median = 3[/tex]
[tex]\sf Mode = none[/tex]
[tex]\sf Range = 5-1=4[/tex]
[tex]\sf Standard\:deviation\:\sigma=\sqrt{\dfrac{\sum (x_i-\mu)^2}{n}}=\sqrt{\dfrac{10}{5}}=\sqrt{2}[/tex]
If we multiply each value by 0.5, the new data set is:
{0.5, 1, 1.5, 2, 2.5}
[tex]\sf Mean\:\mu =\dfrac{\sum x_i}{n}= \dfrac{0.5+1+1.5+2+2.5}{5} = 1.5[/tex]
[tex]\sf Median = 1.5[/tex]
[tex]\sf Mode = none[/tex]
[tex]\sf Range = 2.5-0.5=2[/tex]
[tex]\sf Standard\:deviation\:\sigma=\sqrt{\dfrac{\sum (x_i-\mu)^2}{n}}=\sqrt{\dfrac{2.5}{5}}=\dfrac{\sqrt{2}}{2}[/tex]
Therefore, if each value in the data set is multiplied by 0.5, the mean, median, mode, range, and standard deviation are all scaled by the same amount.
