Answer:
x = 80 degrees
y = 25 degrees
Step-by-step explanation:
First find angle BCA.
We know a line is 180 degrees, and angle BCD is 130. So 180-130 = 50 degrees for angle BCA.
Since it is isosceles (two lines on both sides of triangle ABC) this means the bottom two angles are the same. Now we know the two angles to find missing angle X.
50+50+ x = 180 degrees
x= 180 - 100 = 80 degrees
Next we know triangle BCD is isosceles, so angle BDC and angle CBD are the same. We know the third angle is 130 degrees.
So 180 - 130 = 50 degrees split between two angles that are the same. So one angle is 50/2 = 25 degrees.

IF AABD
ACBE, find the value of x.
27 cm
12 cm
SE
E
23.4 cm
Answer:
[tex] x = 10.4 [/tex]
Step-by-step explanation:
Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:
[tex] \frac{BD}{BE} = \frac{AD}{CE} [/tex]
BD = 12 cm
BE = x
AD = 27 cm
CE = 23.4 cm
Plug in the values
[tex] \frac{12}{x} = \frac{27}{23.4} [/tex]
Cross multiply
[tex] x \times 27 = 23.4 \times 12 [/tex]
[tex] 27x = 280.8 [/tex]
Divide both sides by 27
[tex] x = 10.4 [/tex]
A rental car company charges $68.80 per day to rent a car and $0.08
for every mile driven. Paisley wants to rent a car, knowing that:
• She plans to drive 325 miles.
• She has at most $370 to spend.
Write and solve an inequality which can be used to determine d, the
number of days Paisley can afford to rent while staying within her
budget.
Answer:
5 days maximumStep-by-step explanation:
Given
Daily charge = $68.80Charge per mile = $0.08Target distance = 325 milesMoney limit = $370Required inequality:
68.8d + 325*0.08 ≤ 370Solving for d:
68.8d + 26 ≤ 37068.8d ≤ 344d ≤ 344/68.8d ≤ 5Up to 5 days is the answer

A court holds jurisdiction over five counties, and the juries are required to be made up in a representative manner from the eligible populations of these five counties. An investigator notices that the county where she lives has 14% of the total population of the five counties eligible for jury duty, yet records reveal that over the past five years only 122 out of the 1386 jurors used by the court reside in her county. Do you feel that this constitutes reasonable evidence that the jurors are not being randomly selected from the total population
Answer:
Yes.
I feel that since only about 9% of the jurors are being appointed from the county, instead of the more representative 14%, this constitutes reasonable evidence that the jurors are not being randomly selected from the total population.
Step-by-step explanation:
a) Data and Calculations:
County population proportion = 14%
This implies that the country is supposed to have at least 1,386 * 14% = 194 of the jurors used by the court.
Evidence from records show that the county has only 122 of 1,386 = 9% (122/1,386)
This means that about 72 (194 - 122) jurors are not being appointed from the county.
And 72 represents about 5% of 1,386 (72/1,386). This number is more than half of those being appointed from the county or more than 50% or precisely 59%.
Therefore, this constitutes reasonable evidence that the jurors are not being randomly selected from the total population. The selection is not representative of the population characteristics.

Step-by-step explanation:
The key to finding the distance between two points is to remember that the geometric definition of subtraction is the distance between the two numbers as long as we subtract the smaller number from the larger.
If ABCD is a rectangle, find the measure of angle ABD.
Answer: 31 degrees
Step-by-step explanation: Angle ABD and BDC are alternate interior angles, meaning that they are congruent. Therefore, the measure of angle ABD is 31 degrees.
The measure of angle ABD is 31°
What are alternate interior angles?Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.
Given;
Angle CDB= 31°
Now
Angle ABD= Angle CDB (alternate interior angles)
Angle ABD= 31°
Therefore, angle ABD will be 31°

Given the problem below what mistake did Bob make in solving the equation? Bob and his friends paid $30 for 3 sandwiches and and 3 bottles of water.
-Each sandwich cost the same amount.
-The bottles of water cost $1.50 each.
The equation 3(x + 1.50) = 30 can be used to determine x, the cost of each sandwich. Bob solved the equation using these steps: 3(x + 1.50) =30
3x + 1.50 = 30
3x = 28.50
x = 9.50
Answer:
Bob forgot to distribute 3 to 1.50 in the parentheses
Step-by-step explanation:
Bob made the mistake in his first step.
In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.
But, Bob only distributed it to x, which led him to get the wrong answer.
So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50

determine the coordinates
Answer:
Thus, the rule of a point P(x, y) reflected over the line y = -x
P(x, y) → P'(-y, -x)
we conclude that:
A(3, 4) → A'(-4, -3)B(3, 2) → B'(-2, -3)C(-1, 2) → C'(-2, 3)Step-by-step explanation:
We know that If a point P(x, y) is reflected over the line y = -x, the x-coordinate and y-coordinate tend to change places and the signs are reverses.
Thus, the rule of a point P(x, y) reflected over the line y = -x
P(x, y) → P'(-y, -x)
Thus, we conclude that:
A(3, 4) → A'(-4, -3)B(3, 2) → B'(-2, -3)C(-1, 2) → C'(-2, 3)A 13-ounce box of cereal sells for $3.25. An 18-ounce box of cereal sells for $3.60. Which statement describes the difference in the unit prices of the two boxes of cereal?
