The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
What is the value of x?
Enter your answer in the box.
Answers
Answer: x= 34
Step-by-step explanation:
Given: The measurement of the angles of the quadrilateral are as
First angle=88°
Second angle=108°
Third angle= 2x°
Forth angle =(3x-6)°
Now, The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
Therefore,
Answer: x=59
Step-by-step explanation: first you would do (2x+3)×2+2x=360°
Which simplifies to 6x+6=360°
then solve to get x=59°
then substitute the x=59°
Which will then add up to 360°

1/3 (x+6)= 1/2 (x-3)
1/3x+6/3x = 1/2x-3/2
2/6x-3/6x = -4/2-3/2
-1/6x = -7/2
x = -7 * 6/2-1
x=42/1
x=42
Answer: For the first question ( 0.25(x+4)-3=28) the answer is x=120. How did I found out the answer? I Isolate the variable by dividing each side by factors that don't contain the variable.

The second one is x=6. Isolate the variable by dividing each side by factors that don't contain the variable.

The correct answer for the last one is x=21. Solve for x by simplifying both sides of the equation, then isolating the variable.
Round 4,756 to the nearest thousand.
Answers
Answer:
5,000
Step-by-step explanation:
4 is the thousands digit.
The answer has to be 4,000 or 5,000.
Since the first digit to the right of the 4 is 7, round up to 5.
Answer: 5,000
4,756 would have to be rounded to either 4,000 or 5,000.
4,756 is closer to 5,000 than 4,000 since the second number is over 5 so you round up instead of down.
A triangular prism is attached to a rectangular prism as shown below.
If w = 8 inches, x = 5 inches, y = 20 inches, and z = 11.3 inches, what is the total surface area of the EXTERIOR FACES of the figure?
(Answer choices in picture!!) (I WILL GIVE BRAINLIEST)
Answers
Surface area of the triangular prism:
The triangular prism has two triangular faces and three rectangular faces.
The triangular faces have base (x) of 5 inches and height (y) of 20 inches. The surface area of each triangular face is (1/2) * base * height = (1/2) * 5 * 20 = 50 square inches.
The rectangular faces have dimensions (w, y, and z) of 8 inches, 20 inches, and 11.3 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the three rectangular faces, we get: 2 * (w * y) + 2 * (w * z) + 2 * (y * z) = 2 * (8 * 20) + 2 * (8 * 11.3) + 2 * (20 * 11.3) = 320 + 180.8 + 452 = 952.8 square inches.
Surface area of the rectangular prism:
The rectangular prism has six rectangular faces.
The dimensions of the rectangular prism are (w, x, and y) of 8 inches, 5 inches, and 20 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the six rectangular faces, we get: 2 * (w * x) + 2 * (w * y) + 2 * (x * y) = 2 * (8 * 5) + 2 * (8 * 20) + 2 * (5 * 20) = 80 + 320 + 200 = 600 square inches.
Total surface area of the exterior faces:
To find the total surface area of the exterior faces, we add the surface areas of the triangular prism and the rectangular prism: 50 + 952.8 + 600 = 1,602.8 square inches.
Therefore, the total surface area of the exterior faces of the figure is approximately 1,602.8 square inches. However, none of the given answer choices match this value. Please recheck the given dimensions or options provided.
If Figure A is multiplied by a scale factor of .5, reflected over the x-axis, and translated 3 units left and 8 units down, which is true about A′?
Answers
Answer:
A' has the same shape but not the same size as Figure A.
Step-by-step explanation:
Answer:
A1 has the same shape but not the same size as Figure A.
Step-by-step explanation:
Let's imagine this in our heads:
1. Figure A is multiply by a scale factor of 0.5
Remember when you learned about similarity? Similar figures have a scale factor between them, so the shape that you have at this step is similar to the original.
2. Reflected over the x-axis.
Remember reflection? Reflection is a congruence transformation: the product of a reflection is the same shape and size as the original. Therefore, the figure stays the same at this step, just reflected over the x-axis.
3. Translated 3 units left and 8 units down.
Translation is a congruence transformation as well. The location of the figure will change, but the size and shape will not.
So, the end result is a figure that is similar to the original, and has a scale factor of 0.5 with the original.
This means that it is smaller than the original shape: so we can rule out the first option.
A reflection across the x-axis means that the resulting figure will be on the opposite side of it. Since the original shape is above the x axis, the resulting figure after a reflection will be below. We can rule out the second option.
Now, we get to the third one. A1 has the same shape but not the same size as Figure A. This is true. That is the definition of similar triangles, and we know that triangles A and A1 share a scale factor of 0.5

what is 12 divided by 3/4?
correct answer gets brainliest!
Answers
Step-by-step explanation:
To divide by a fraction, we can invert the fraction and multiply.
So, 12 divided by 3/4 can be written as:
12 * 4/3
Simplifying this expression, we get:
= 48/3
= 16
Therefore, 12 divided by 3/4 is equal to 16.
12 divided by 1/3 is 1
9 divided by 1/4 is 2.25
1/8 divided by 4 is 0.5
12 divided by 1/3 is 4

Based on the information in the histogram, a reasonable conclusion would be that the exact time it took the students to finish the test is not indicated. Therefore, option B is the correct answer.Mrs. Brim made a chart to see how long it took her students to finish a test. However, the chart or histogram only shows how many students took a certain amount of time to finish the test and not their exact finishing time. Therefore, it's not possible to determine how long each student took to finish the test accurately.

Karim multiplies two numbers written in scientific notation and finds that the product is 0.0258 × \(10^{-8 }\)
Explain the next steps Karim should take to solve this problem. Be specific.
Answers
Answer:
To solve the problem, Karim can follow these specific steps:
Understand scientific notation: Ensure that Karim understands the basic concept of scientific notation, which represents numbers as a product of a decimal number between 1 and 10 and a power of 10. For example, 0.0258 × 10^-8 is in scientific notation.
Convert to standard notation: Karim should convert the given numbers in scientific notation to standard notation. In this case, he can multiply 0.0258 by 10 raised to the power of -8. The result will be a decimal number in standard notation.
Perform the multiplication: Multiply the two numbers without considering the scientific notation. Multiply 0.0258 by 10 raised to the power of -8. This will give the actual product of the two numbers in standard notation.
Adjust the answer to scientific notation: After performing the multiplication, Karim should evaluate the result and adjust it to scientific notation if necessary. If the result is a very small or very large number, it is often expressed in scientific notation for convenience.
Finalize the answer: Write down the final answer in scientific notation, if applicable. Make sure to include the decimal number between 1 and 10 and the corresponding power of 10.
By following these steps, Karim will be able to solve the problem and obtain the accurate result in scientific notation, if necessary.

Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous
Answers
Answer:
This example represents discrete data.
Step-by-step explanation:
Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.
In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.
Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

Please help, I really struggle with math a lot and now these two different answers are confusing me even more. If you can also explain why which of the two answers are correct that would be amazing! If you can't answer please comment! Thank you so so so much!!!
Answers
Answer:
x = 1
Step-by-step explanation:
4x + 8=-7x +19
add 7x to both sides
4x + 7x+8=-7x+7x +19
11x + 8=19
subtract 8 from both sides
11x + 8-8= 19-8
11x=11
x = 1
Answer: X=1
Step-by-step explanation:
Add 7x over to the 4x to get 11x. 11x+8=19 subtract 8 on both sides to get 11x=11. Divide and you get 1.
