Answer:
2e3t = 32 since you can divide by 3 on both sides.
in which of the following quadrilaterals does a diagonal not always divide the quadrilateral into two regions of equal area: rhombus, square, rectangle, trapezoid, parallelogram?
The trapezoid is the only quadrilateral in the given list in which a diagonal does not always divide the quadrilateral into two regions of equal area.
This is because a trapezoid has two parallel sides of different lengths, so the diagonal that connects the non-parallel sides will not bisect the trapezoid's area. In contrast, a rhombus, square, rectangle, and parallelogram all have diagonals that bisect their areas, meaning that each half of the quadrilateral has an equal area.
In a trapezoid, a diagonal does not always divide the quadrilateral into two regions of equal area. Unlike squares, rectangles, and parallelograms, where diagonals create congruent triangles, trapezoids do not guarantee this property. In a trapezoid, diagonals can create triangles with different areas due to the uneven side lengths and angles. Thus, the trapezoid is the quadrilateral in which a diagonal may not always create equal-area regions.

Find the percent decrease from 133 to 120. Round your answer to the nearest tenth
Answer:
Approximately - 9.7%
Step-by-step explanation:
By using the percent change formula, you will be able to calculate the percent decrease.
(b-a)/a times 100 <-- (percent change formula)
(120-133)/133 times 100
-13/133 times 100
-9.7744%
Answer:
9.8% decrease
Step-by-step explanation:
You want the percent decrease from 133 to 120.
Percent changeThe amount of change as a percent can be found using the formula ...
percent change = ((new value)/(old value) -1) × 100%
Here, the new value is 120, and the old value was 133. The change is ...
percent change = (120/133 -1) × 100% ≈ (0.90226 -1) × 100%
= -0.09774 × 100% ≈ -9.8%
The change from 133 to 120 is a 9.8% decrease.
__
Additional comment
When the sign of the change is negative, as here, the change is a decrease. If the sign is positive, the change is an increase. That is, a change of -9.8% is a 9.8% decrease. (You can use either the minus sign or the word "decrease" to indicate the direction of the change. The acceptable form of the answer will depend on your grader.)

Answer:
1) AD = 9 in
2) DE = 9.25 in
3) ∠EDC = 36°
4) ∠AEB = 108°
5) 11.5 in
Step-by-step explanation:
1) AD = BC = 9in
2) AC = BD (diagonals are equal)
⇒ BD = 14.25
⇒ BE + DE = 14.25
⇒ 5 + DE = 14.25
DE = 9.25
3) Since AB ║CD,
∠ABE = ∠EDC = 36°
4) ∠ABE = ∠BAE = 36°
Also ∠ABE + ∠BAE + ∠AEB = 180 (traingle ABE)
⇒ 36 + 36 + ∠AEB = 180
∠AEB = 108
5) midsegment = (AB + CD)/2
= (8 + 15)/2

A fish is swimming at a vibrant rate toward the ocean floor. The equation y=-7x-3 can be used to represent this distinction, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming. Which statement best describes the depth of the fish,given this equation.
A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second .
C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
Answer:
C. From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
Answer:
C
Step-by-step explanation:
y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.

The Pythagorean theorem states that for any given right triangle a+b+=c. Using the Pythagorean theorem, what should be that the relationship between the areas of the three squares
The Pythagorean Theorem is a fundamental concept that relates to the sides of a right-angled triangle, and it can also be used to understand the relationship between the areas of the squares constructed on the sides of the triangle.
The area of a square is given by the formula A = s², where s is the length of one of its sides. Therefore, the areas of the three squares are:
Area of the square with side a = a²
Area of the square with side b = b²
Area of the square with side c = c²
Now, let's compare the areas of the squares. We can start by subtracting the area of the square with side a from the area of the square with side c:
c² - a²
Using the Pythagorean Theorem, we know that c² = a² + b². Substituting this into the above expression, we get:
c² - a² = (a² + b²) - a² = b²
This tells us that the difference between the area of the square with side c and the area of the square with side a is equal to the area of the square with side b. In other words:
c² - a² = b²
This is known as the Pythagorean identity. It states that in any right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. We can also rearrange this identity to obtain the following:
c² = a² + b²
This is the Pythagorean Theorem that we are familiar with. Therefore, we can conclude that the relationship between the areas of the squares constructed on the sides of a right-angled triangle is given by the Pythagorean identity: the difference between the area of the square on the hypotenuse and the area of the square on the shorter side is equal to the area of the square on the other shorter side.

Demand over the past three months has been 700, 750, and 900. Using a three-month moving average, what is the forecast for month four?
The three-month moving average is calculated by adding up the demand for the past three months and dividing the sum by three.
To calculate the forecast for month four, we need to find the average of the demand over the past three months: 700, 750, and 900.
Step 1: Add up the demand for the past three months:
700 + 750 + 900 = 2350
Step 2: Divide the sum by three:
2350 / 3 = 783.33 (rounded to two decimal places)
Therefore, the forecast for month four, based on the three-month moving average, is approximately 783.33.
Keep in mind that the three-month moving average is a method used to smooth out fluctuations in data and provide a trend. It is important to note that this forecast may not accurately capture sudden changes or seasonal variations in demand.
Can you use SSA to prove triangles congruent?
No, we can not use SSA to prove triangles are congruent.
The side-side-angle congruence rule also referred to as the SSA congruence rule, deals with the congruence of two triangles.
According to the SSA congruence rule, two sides and an angle that is not contained between them must be equal to two sides and an angle of the other triangle in order for the two triangles to be equal. Due to the possibility that the sides of the two triangles may not be on the same corresponding sides, this congruence rule does not consider two triangles to be congruent. It's possible that the two triangles will wind up being of different sizes and shapes. The SSA congruence rule is therefore invalid.

The population of a town is increasing at a constant rate of 4.7% each year. At the beginning of 2010 the population was 42,000. Find the size of the population at the beginning of 2016. Give your answer to 3 sf.
Answer:
The population at the beginning of 2016 is 55,326.
Step-by-step explanation:
Giving the following information:
Population 2010 (PV)= 42,000
Growth rate (g)= 4.7% = 0.047
Number of years (n)= 6 years
To calculate the population at the beginning of 2016, we need to use the following formula:
FV= PV*(1+g)^n
FV= 42,000*(1.047^6)
FV= 55,326
The population at the beginning of 2016 is 55,326.

To find:
The measure of angle 1.
Solution:
Exterior angle theorem: In a triangle, the measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.
Using Exterior angle theorem, we get
\(101^\circ =31^\circ +m\angle 1\)
\(101^\circ -31^\circ =m\angle 1\)
\(70^\circ =m\angle 1\)
Therefore, the measure of angle 1 is 70 degrees.
