1. Let Triangle ABC be congrent to Triangle DEF. Find m< E.
the value of m< E is-----------------.
The value of m∠E is 120°
Define Congruent angles
Congruent angles are two or more angles that are identical to one another.Congruent angles can be acute, obtuse, exterior, or interior angles.Given,
The Δ ABC be congruent to Δ DEF.
Since, the triangles are congruent, B and E are automatically congruent, since they are corresponding angles.
First let's find the value of y,
To find y, equate the measure of y like this
95 + y = 6y - 30
95 + 30 = 6y - y
125 = 5y
y = 25
Now, substitute the value of y in ∠E
∠E = 6y - 30
∠E = 6* 25 - 30
∠E = 120°
Hence, the value of m∠E is 120°

Applying the Pythagorean theorem, the missing side of each of the right triangle are:
i. c = 15.8 m
ii. s = 24.1 cm
iii. a = 12.8 feet
iv. t = 4.6 inches
Pythagorean Theorem.Pythagorean theorem is one that can be used to determine the third unknown side of a right angled triangle. It is given by:
/Hyp/^2 = /Adj/^2 + /Opp/^2
The missing side of each of the right triangle can be determined as:
1. Let the value of unknown hypotenuse side by represented by c, so that:
/Hyp/^2 = /Adj/^2 + /Opp/^2
c^2 = /13/^2 + /9/^2

The probability that at least one die is a 5, given that the sum of the numbers on the dice is at least 8 = 2/5
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
The outcomes when the sum dice is 8 are

The percentage of population between 130 and 102 is 68%.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the mean is 116 and the standard deviation is 14. Therefore, the approximate population between the given range of 102 to 130 is,
P(102 ≤ X ≤ 130) = P(X ≤ 130) - P(102 ≤ X)

The school is 3.64 miles from Tonya's house and 1.27 miles from Jamal's house. How much farther from school is Tonya's house than Jamal's house? Complete the explanation on how you can use a quick picture to solve the problem.
Answer: Tonya's house is 2.37 miles farther from the school than Jamal's house.
Step-by-step explanation: To solve this problem using a quick picture, we can draw a line segment to represent the distance from the school to Tonya's house, and another line segment to represent the distance from the school to Jamal's house. We can then use a ruler to measure the length of each line segment and subtract the length of the line segment representing the distance to Jamal's house from the length of the line segment representing the distance to Tonya's house.
For example, if we draw a line segment that is 3.64 inches long to represent the distance from the school to Tonya's house and a line segment that is 1.27 inches long to represent the distance from the school to Jamal's house, then we can use a ruler to measure the lengths of the line segments and find that the line segment representing the distance to Tonya's house is 3.64 - 1.27 = 2.37 inches longer than the line segment representing the distance to Jamal's house. This means that Tonya's house is 2.37 miles farther from the school than Jamal's house.

Ashley's hair grew 1 and 1/2 inches in 2 and 3/4 of a month. At what
Rate did ashley's hair grow per month?
Ashley's hair grew at a rate of approximately 0.545 inches per month.
What is the rate of change?
Rate of change problems can generally be approached using the formula R = D/T, or rate of change equals the distance traveled divided by the time it takes to do so.
To find the rate at which Ashley's hair grew per month, we need to divide the total amount of hair growth by the number of months.
First, let's convert the units to a common denominator. 1 and 1/2 inches is the same as 3/2 inches, and 2 and 3/4 months is the same as 11/4 months.
Now we can divide the total amount of hair growth (3/2 inches) by the number of months (11/4 months) to get the rate at which Ashley's hair grew per month:
(3/2 inches) / (11/4 months) = (3/2) * (4/11) inches/month
= 6/11 inches/month
= approximately 0.545 inches/month

A. If the mA = 60, then ABC is an equilateral triangle.
B. If ABC is not an equilateral triangle, then the mA does not equal 60.
C. If the mA does not equal 60, then ABC is not an equilateral triangle.
Answer is C!
The true statement from the given options is C. If the mA does not equal 60, then ABC is not an equilateral triangle.
Equilateral triangle:An equilateral triangle is one in which the angles and all three sides are equal. An equilateral triangle is also called an equiangular triangle since each of its angles has a value of 60 degrees.
The equal angle in an Equilateral triangle = 60°
Here we have 3 options
A. If the mA = 60, then ABC is an equilateral triangle.
B. If ABC is not an equilateral triangle, then the mA does not equal 60.
C. If the mA does not equal 60, then ABC is not an equilateral triangle.
Here we need to justify which of the given point will be true in the case of Equilateral Triangles.
Given
Option A: If the mA = 60, then ABC is an equilateral triangle.
With the measurement of A = 60°, here we can't conclude that ABC is an equilateral triangle because there is a possibility that the remaining angles are not equal to 60°
Option B: If ABC is not an equilateral triangle, then the mA does not equal 60.
Any type of triangle can have an angle that is equal to 60° so the given statement is wrong.
Option C. If the mA does not equal 60, then ABC is not an equilateral triangle.
As we know each angle of an equilateral triangle is 60°, So it is true that If the mA does not equal 60, then ABC is not an equilateral triangle.

f'(x)=6/2 * x^2 + C ==> simplify the first derivative
f'(x)=3 * x^2 + C ==> f'(x)=3(x^2) + C
f'(-3)=3((-3)^2) + C ==> plug in -3 into the derivative equation
f'(-3)=3(9) + C ==> simplify

Define Geometric Progression
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is,
aₙ = a₁ · rⁿ⁻¹.
The geometric sequence,
5, -25, 125 ....
from here,we know
a₁ = 5
Calculate the ratios of all the adjacent terms ,
r = aₙ₊₁ / aₙ
r = -25/5 = -5
r = 125/-25 = -5
We know, the formula for geometric sequence is
aₙ = a₁ · rⁿ⁻¹
Where, a₁ = initial term
r = common ratio
Now, we need to find 12th term so for that n = 12
Now, plug in the values
aₙ = a₁ · rⁿ⁻¹
a₁₂ = 5 * (-5) ¹²⁻¹

LMNO is a parallelogram. If PN=7x-13PN=7x−13 and LP=8x-19LP=8x−19, find LPLP. Round to the nearest tenth, if necessary.
A parallelogram is a type of quadrilateral which has opposite sides to be equal. So that the value of LP required is 26 units.
Generally, all four sided shapes or figures can be classified as quadrilateral. Some of these examples are; cube, square, rectangle, rhombus, trapezoid, parallelogram etc.
A parallelogram is a form of shape which has four sides with two opposite sides to have equal length.
From the parallelogram LMNO, it can be deduced that;
