The value of the angle m∠BDC is 105°.
What is third angle theorem?If the other two sets are both congruent, then the third angles are equal.The third pair of angles must be congruent if two angles in one triangle are congruent with two angles in another triangle. The Third Angle Theorem refers to this.The Triangle Sum Theorem can be thought of as an extension of the Third Angle Theorem. The Triangle Sum Theorem states that once two angles in a triangle are known, you automatically know the third. This indicates that if you have two triangles with two pairs of congruent angles between them, you will receive the same result both times when you apply the Triangle Sum Theorem to each triangle to determine the third angle. The third pair of angles must therefore likewise be similar.Let separate the triangles and find missing angle in triangle with given angles.

by applying third angle theorem,
∠CAD=∠DBC=45°
∠ADC=∠BCD=30°
Then, ∠DBC+∠BCD+∠BDC=180°
45°+30°+BCD=180°

Two trains, Train A and Train B, weight a total of 301 tons. Train A is heavier than Train B. The difference of their weights is 217 tons. What is the weight of each train?
Answer:
Train A = 259
Train B = 42
Step-by-step explanation:
Answer:
Train A's weight is 259 tons
Train B's weight is 42 tons
Step-by-step explanation:
Let x represent train A's weight, and y represent train B's weight.
Since they both weigh 301 tons
The equation is: x+y = 301
The difference in their weight is 210, and train A is heavier
So equation is: x - y = 217
x+ y =301
x- y = 217
2x = 518
x = 259 tons
Now find train B
301 - 259 = 42 tons

triangle A"B"C" is formed using the translation (x+1,y+1) and the dilation by a scale factor of 3 from the origin. Which equation explains the relationship between BC and B"C"
Answer:
the equation that explains the relationship between BC and B"C" is:
BC = 2 * B"C"
This equation states that the length of BC is equal to twice the length of B"C".
Step-by-step explanation:
If triangle A"B"C" is formed using the translation (x+1,y+1) and the dilation by a scale factor of 3 from the origin, then the coordinates of the vertices of triangle A"B"C" can be expressed as follows:
A" (x+1, y+1)
B" (3x+3, 3y+3)
C" (3x+6, 3y+6)
To find the equation that explains the relationship between BC and B"C", we can use the distance formula to find the length of both segments. The distance formula is:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
Where (x1, y1) and (x2, y2) are the coordinates of the two points.
Using the distance formula, we can find the length of BC as follows:
BC = √((3x - x)^2 + (3y - y)^2)
= √((2x)^2 + (2y)^2)
= √(4x^2 + 4y^2)
= 2√(x^2 + y^2)
We can also find the length of B"C" as follows:
B"C" = √((3x+6 - 3x-3)^2 + (3y+6 - 3y-3)^2)
= √((3)^2 + (3)^2)
= √(9 + 9)
= √(18)
= 3√(2)
Which of the following is equal to the square root of the cube root of 6? (4 points)
A. 6 to the power of one sixth
B. 6 to the power of one third
C. 6 to the power of two thirds
D. 6 to the power of three halves
Answer:
A. 6 to the power of one sixth
Step-by-step explanation:
To find the square root of the cube root of 6, you need to first find the cube root of 6, which is equal to 2. Then, you need to take the square root of 2, which is equal to 1.4142135623730951. Therefore, the square root of the cube root of 6 is equal to 1.4142135623730951.
To express this value using exponents, you can use the property that the square root of x is equal to x to the power of one half. Therefore, the square root of the cube root of 6 is equal to 6 to the power of one half of one third, which simplifies to 6 to the power of one sixth.

A rectangular poter ha an area of 504 quare centimeter. The width of the poter 14 centimeter. How long i the poter? Write equation to how your work
Answer:
36 cm.
Step-by-step explanation:
In the question, we have been given ,
Area of the rectangle=504cm2
The width of the rectangle=14cm
The length of the rectangle=?
The formula for the area of the area of the rectangle is L×B. Thus A=L×B(W).
So 504cm2= L×14.
Now divide both sides by 14
504cm2/14=14L/14
Therefore L= 36cm
if the p value is less than a in a two-tailed test, a. the null hypothesis should not be rejected. b. the null hypothesis should be rejected. c. a one-tailed test should be used. d. more information is needed to reach a conclusion about the null hypothesis.
In a two-tailed test, the null hypothesis should be rejected in favor of the alternative hypothesis if the p-value is smaller than a. Therefore option (b) is the right answer.
What is null hypothesis?A common statistical theory called the null hypothesis asserts that there is no statistical relationship or significance between two sets of observed data and measured events for a given single observed variable.
A p-value less than 0.05 (usually 0.05) is considered statistically significant when using the P-value technique to conduct any hypothesis test. With less than a 5% chance that the null is true, it provides strong evidence against the null hypothesis (and the results are random). The alternative hypothesis is thereby accepted, whereas the null hypothesis is rejected.

The total number of boxes of inventory which is loading on the truck by the workers are 1,200 boxes.
What is percentage of a number?
Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.
Workers are loading boxes onto a truck . So far, they have loaded 48 boxes onto the truck.
According to their inventory, they still need to load 96% of boxes on the truck. There must be 100% box at the start of the loading. Thus, the percentage of boxes they have load,
p=100-96 = 4%
Thus the percentage of boxes they have load in the truck is 4%. This is equal to the 48 boxes they have loaded.
Let suppose there is x number of total boxes. Thus the 4 percent of x will be equal to the 48.
(4/100)x=48
x = 4800/4 = 1200
Thus, the total number of boxes of inventory which is loading on the truck by the workers are 1,200 boxes.

You would add 5x + 2x = 7x
Substitute 5 for x and that = 5(5)= 35 +2(5)= 10= 45
and do it for 7(5)= 35-1 = 34 too
You can't make them equal
Following the pattern in (5)(3)+(2)(3) = (5+2)(3), we could do the same thing with 5x+2x = (5+2)x. We're basically un-distributing the common factor from each term.
And now with (5+2)x, we can add the 5 and 2 to get 7x.
If we substitute different values into 5x+2x, it works out to add up to 7 times that same substituted value. For example:
(5)(9)+(2)(9)=45+18=63
(7)(9)=63
If we substitute 9 into 7x-1, then we end up with 63-1 = 62.
In fact, any number we put into 5x+2x will always be one more than 7x-1. So, no, there doesn't seem to be any value of x that would make these equal. Since 5x+2x=7x, then 7x-1 will always be one less than 7x.

Answer:
Step-by-step explanation:
Rewrite equations: x+y=6;2x−3y=4
Solve x+y=6 for x: x+y+−y=6+−y (Add -y to both sides)
x=−y+6
Substitute −y+6 for x in2x−3y=4: 2x−3y=4
2(−y+6)−3y=4
−5y+12=4 (Simplify both sides of the equation)
−5y+12+−12=4+−12 (Add -12 to both sides)
−5y=−8
−5y/−5=−8/−5 (Divide both sides by -5)
y=8/5
Substitute 8/5 for y in x=−y+6:
x=−y+6
x=−8/5 +6
x=22/5 (Simplify both sides of the equation)
Answer: x=22/5 and y=8/5

In this triangle, what is the value of x?
Answer: 4.46cm
Step-by-step explanation:
Use [SOH CAH TOA]
We have two sides that are labeled. Use 85cm and x.
Using the angle 63 degrees would mean you are using SOH.
SOH = Opposite/Hypotenuse.
If the above is true, then: Sin63 = x/85
Since we don't know what x is, you want to move 85 to the other side.
85(Sin63) = x
Now, you can find x. Multiply 85 and Sin63. Your answer should be 4.46 (if rounded to 2 decimals).
