Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning.
Is triangle DCA congruent to triangle BCA? Explain.
Answers
Proving congruency:
CA = CA, reflexive
m ∠DCA = m ∠BAC, alt interior ∠
m ∠BCA = m ∠DAC, alt interior ∠
triangle DCA = triangle BCA, ASA
Supplementary angles means a pair of angles adding to 180 degrees.
180 degrees would be a straight angle.
∠DCA + ∠BCA = ∠DCB, not a straight angle.

Answers
Answer: Image will give answer
Step-by-step explanation: Look at image for answer
Answer:
480.0384
Step-by-step explanation:
to solve for the percentage you can start with this equation... [tex]\frac{27.78 * 1728}{100}[/tex]
which can be further simplified to [tex]\frac{48003.84}{100}[/tex]
which means the answer will be [tex]\frac{480.0384}{1}[/tex]
Answer these two questions:
Suppose that 60% of the students at your school favor a proposed school policy that would ban cell phones at school. Also suppose that every student in your class selected a different random sample of 50 students from your school and calculated the proportion of students in the
sample who favor the ban.
5. If your class constructed a dot plot of all these sample proportions, where would you expect the dot plot to be centered?
6. If every student had selected a random sample of size 25 instead of a sample of size 50, would you expect a dot plot of the sample proportions to be more spread out or less spread out than in a dot plot of sample proportions for samples of size 50?
Answers
Answer:
at 50 and 6 yes because 50 is more than 25 and will get bigger

We can see that both circles have the same radius. This means that the circles have same areas. Therefore, the area of the figure is the difference of the area of the rectangle and the sum of the area of the two circles.
Area of rectangle:The area of a rectangle is the vertical side length multiplied with the horizontal side length.
Area of rectangle = Length × WidthArea of rectangle = 12 × 6Area of rectangle = 72 ft²Area of circle:Substitute the radius in the formula to determine the area of the circle.
Area of circle = πr²Area of circle = π(3)²Area of circle = π(9)Area of circle ≈ (3.14)(9)Area of circle ≈ 28.26 ft²Area of shaded region:Area of shaded region ≈ Area (rectangle) - [Area (circle) + Area (circle)]Area of shaded region ≈ 72 - (28.26 + 28.26)Area of shaded region ≈ 15.48 ft² ≈ 16 ft² (Option E)Solution (Question 2):To determine the area of the shaded region, we need to determine the area of the square, then subtract it with the area of the circle.
Area of square:The area of a square is the measure of its side, squared. Therefore,
Area of square = (Side)²Area of square = (16)²Area of square = 256 in²Area of circle:The formula that determines the area of a circle is πr². We can tell that the radius of the circle is required to determine the area of the circle, as the formula to determine the area of a circle (πr²) includes the variable "r", which is the radius of the circle.
How to determine the radius of the circle?
Since we are given the diameter of the circle, we can determine the radius of the circle by creating an equation that represents the relationship between a diameter and radius. Then, substitute the diameter in the equation and solve for the radius of the circle.
Determining the radius of the circle:
It should be noted that the diameter is twice larger than the radius. Therefore, the equation that represents the relationship between the radius of the circle and the diameter of the circle is;
Diameter = 2(Radius)Substitute the diameter in the equation to determine the radius of the circle.
16 inches = 2(Radius)Divide 2 to both sides of the equation and simplify both sides:
16 inches = 2(Radius)16 inches/2 = 2(Radius)/2Radius = 8 inchesSubstitute the radius in the formula to determine the area of the circle.
Area of circle = πr²Area of circle = π(8)²Area of circle = π(64)Take π as 3.14
Area of circle = (3.14)(64)Area of circle ≈ 200.96 inches²Area of shaded region:Area of shaded region ≈ Area of square - Area of circleArea of shaded region ≈ 256 - 200.96Area of shaded region ≈ 55.04 inches² ≈ 55 inches² (Option C)Final answers:1) Option E2) Option CComplete the square for: 3[tex]x^2[/tex]-18x-12

Step-by-step explanation:
Alright lets take a deep look at the question. It is asking for the miles/gallon, or miles per gallon so we already have our format set. Now for the important information, how do we find unit rate?
Simply put, we divide the unit numerator by the quantity in the denominator. Alright, so we have 39.5/1.25 already, which gives us a highway to our answer through dividing the numbers as they are shown.
Therefore, our unit rate is 31.6 miles per every gallon of fuel.

God I love Triangles
1: b=36 units
2: C.
1st Explanation:
Given the triangle's sides are to scale, you can take the larger one and divide a side value by it's scaled version to find the rate of change.
In this instance, i took 45/10 and got 4.5, I checked with the other side and found 27/6 also was equivalent to 4.5. This meant the scale from Triangle 1 to Triangle 2 was upscaled by a multiple of 4.5 ...
I took the non-scaled side, and used the common multiple that is present on the other sides, and I found 8x4.5=36.
So, side b, the un-labeled, target side on Triangle 2, equals 36 units. (never forget the units when written, remember this for your future.)
2nd Explanation:
The word problem presents an estimated guess that we are to evaluate it's accuracy of.
I started by reading Laamars, prediction, and checked for any obvious answers. I did not find one, so I moved on to do the math to the estimated penny, by doing:
-Lamar has 1 Full Jar worth $51.45
Value: (51.45)
-Lamar has two identical (same, nearly) jars
Value: (2x51.45)
-Lamar has a 3/4 full jar. So, I converted 3 divided by 4 to .75,
Value: (.75x51.45)
-Lamar has a 1/2 full jar. So, I used one half of 51.45 with the equation: Value: (51.45/2 OR .5x51.45)
So, gathered the values and got the sum of:
Estimated Value = 51.45+(51.45x2)+(.75x51.45)+(.5x51.45) = $218.66
With this in mind, we know Lamar OVERESTIMATED, so we can eliminate answer choices A and B. When you read D, it is already known that the exact value may not be $51.45, so, by process of elimination, I concluded that Lamar most likely overestimated becuase "He has Just over 4 containers, and 4x50=200"
3+.75+.5=4.25, so the statement "just over 4" is true.

A concrete truck loaded with concrete weighs up to 26 tons. About how many pounds does the loaded truck weigh?
Answers
Answer:
Step-by-step explanation:
1 ton = 2000 ponds
Multiply: 2000x30=?
2000x30=60000
Answer:
52000 pounds
Step-by-step explanation:
On ton is equivalent to 2000 pounds.
We can use this information to set up a unit converter. See the format for a unit converter below:
[tex]\text{Unit We Have}\ \cdot\ \frac{\text{Unit We Want}}{\text{Unit We Have}}[/tex]
Substitute the given values into the equation:
[tex]26\text{ tons}\ \cdot\ \frac{2000 \text{ pounds}}{1 \text{ ton}}=26\ \cdot\ 2000 \text{ pounds}=52000 \text{ pounds}[/tex]
The truck weighs about 52000 pounds.
