What is the measure of E, in degrees?
A. 130
B. 155
C. Cannot be determined
D. 125
Please don't answer just for points!
The measure of angle E is 0 degrees not provided in the options (A, B, C, or D), and the correct answer is "Cannot be determined."
To find the measure of angle E in degrees that the sum of angles in a triangle is 180 degrees.
From the given triangle, two angles with measures 50 degrees each (angle A and angle B), and one angle with a measure of 80 degrees (angle D).
To find the measure of angle E, we can use the equation:
Angle E = 180° - (angle A + angle B + angle D)
Angle E = 180° - (50° + 50° + 80°)
Angle E = 180° - 180°
Angle E = 0°

What is the distance between points
(9, −7)
and
(9, 4)
on a coordinate plane?
Final answer:
The distance between the points (9, -7) and (9, 4) is calculated by finding the absolute difference between the y-coordinates since the x-coordinates are the same. The distance is 11 units.
Explanation:
To calculate the distance between two points on a coordinate plane, you can use the distance formula, which is derived from the Pythagorean theorem. However, in this particular case, since the x-coordinates of the points (9, -7) and (9, 4) are the same, the distance is simply the absolute difference between the y-coordinates.
The formula to find the distance between two points (x1, y1) and (x2, y2) is:
d = √((x2 - x1)² + (y2 - y1)²)
So, substituting the known values:
d = √((9 - 9)² + (4 - (-7))²) = √(0 + 11²) = √121 = 11
Therefore, the distance between the points (9, -7) and (9, 4) on a coordinate plane is 11 units.

Write about a real-world situation that can be solved using a two-step equation. Then write the equation and solve the problem.
A real-world situation that can be solved using a two-step equation is calculating the total cost of a shopping trip. Let's say you go to a store and buy some items. Each item costs $5, and you buy 3 items. You also have a $10 coupon. To find the total cost, we can use a two-step equation: 3 * 5 - 10 = x. Solving the equation, we get x = 15.
Explanation:A real-world situation that can be solved using a two-step equation is calculating the total cost of a shopping trip. Let's say you go to a store and buy some items. Each item costs $5, and you buy 3 items. You also have a $10 coupon. To find the total cost, we can use a two-step equation:
Step 1: Write the equation. Let x be the total cost.
Step 2: Solve the equation. The cost of the items is $5 per item, so the first step is to multiply 3 (number of items) by 5 (cost per item). Then subtract the $10 coupon from the total cost. The equation becomes 3 * 5 - 10 = x. Solving the equation, we get x = 5. Therefore, the total cost of the shopping trip is $15.

What is the area of this polygon 15m 10m 8m 9m
The provided data is insufficient to accurately calculate the area of the polygon. With an assumption that the shape is a rectangle and the lengths are 15m and 8m, the area would be 120 square meters.
Explanation:To calculate the area of a polygon, it's ideal to break down the polygon into simpler shapes like rectangles or triangles, for which we have well established formula for area. However, the information you've provided is inadequate to define a specific polygon shape like a rectangle or a square. Four sides could suggest a rectangle or a quadrilateral, but we don't know two essential properties: the arrangement of these sides and the measure of angles. For instance, if it was a rectangle, we'd look for pairs of equal lengths. If your shape is indeed a rectangle, and we assume that 15m and 8m are the length and width (or vice versa), we could calculate the area. For a rectangle, the area is calculated as length multiplied by width. In this case, it would be 15m*8m = 120 square meters.

A box of cereal contains 23.4 ounces. It costs $5.49. What is the cost to the nearest cent of the cereal per ounce
Answer:
The cost of one ounce of cereal is $0.24
Step-by-step explanation:
We are given the following information in the question:
Amount of cereals a box contain = 23.4 ounces
Cost of one box = $5.94
Cost of cereal per ounce =
Formula:
[tex]\text{Cost of one ounce of cereal} = \\\\\displaystyle\frac{\text{Cost of cereal}}{\text{Amount of cereal in a box}}[/tex]
Putting the values, we have:
[tex]\text{Cost of one ounce of cereal} = \displaystyle\frac{5.49}{23.4} = 0.2347 \approx 0.24[/tex]
Hence, the cost of one ounce of cereal is $0.24

crystal's mother kept a record of. crystal's. height at different ages. she recorded the information in a table. is the relationship between crystal's age and her height proportional? explain.
The relationship between Crystal's age and her height is determined by examining the ratios of age to height for different entries in the table. If the ratios are equal, then the relationship is proportional.
Explanation:To determine if the relationship is proportional, compare the ratios of Crystal's age to her height for different entries in the table. If the ratios are equal, then the relationship is proportional. If the ratios are not equal, then the relationship is not proportional.
For example, if Crystal's age is 10 and her height is 50 inches, the ratio would be 10/50 = 0.2. If Crystal's age is 20 and her height is 100 inches, the ratio would be 20/100 = 0.2. Since the ratios are equal, the relationship between Crystal's age and her height is proportional.
