Cassie is designing a wheelchair ramp for a school. her original design had a height of 3 feet and a base of 24 feet. Her new design must have a height of 3 feet and height-to-base ratio of 1:12.
How long will the base ramp be in the new design?
A 6 feet
B 12 feet
C 30 feet
D 36 feet
Answer:
D. 36 feet
Step-by-step explanation:
if Cassie's new ratio is 1:12 height-to-base, and her height is 3, plug that information into the ratio.
1:12 = 3:b
to go from 1 to 3, you multiply 1 by 3, so you will need to multiply 12 by 3 to get the new base.
3x12 = 36
D. 36 feet

Given:
Vertical angles.
One angle is 85°.
To find:
The measure of ∠1, ∠2 and ∠3.
Solution:
∠2 and 85° are vertically opposite angles and ∠1 and ∠3 are vertically opposite angles.
Vertical angle theorem:
If two lines are intersecting, then the vertically opposite angles are congruent.
⇒ m∠2 = 85°
Sum of the adjacent angles in a straight line = 180°
m∠2 + m∠3 = 180°
85° + m∠3 = 180°
Subtract 85° from both sides.
85° + m∠3 - 85° = 180° - 85°
m∠3 = 95°
By vertical angle theorem:
⇒ m∠1 = m∠3
⇒ m∠1 = 95°
Therefore m∠1 = 95°, m∠2 = 85° and m∠3 = 95°.
How many unique triangles can be drawn with side lengths 12 cm and 16 cm and a 50 ° included angle
Final answer:
Using the Law of Cosines with the given sides and angle, we find that only one unique triangle can be drawn since a specific third side length can be determined, allowing only one possible triangle to exist.
Explanation:
To determine how many unique triangles can be drawn with side lengths of 12 cm and 16 cm and an included angle of 50°, we use the concept of triangle construction. The Law of Cosines allows us to find the range of possible third sides that could form a triangle:
c² = a² + b² - 2ab*cos(C),
where:
c is the unknown side length,a and b are the known side lengths (12 cm and 16 cm), andC is the included angle (50°).The solution to this equation will determine if we have a single unique triangle, more than one triangle, or no triangle at all. In this case:
c² = 12² + 16² - 2*12*16*cos(50°)
Calculating the value, we can then check if 0 < c < 28 (because for a triangle to exist, the sum of any two sides must be greater than the third side). If the third side falls within this range, a unique triangle can be drawn. As a triangle with two sides and an included angle will only yield one possible third side length, there can be only one unique triangle formed.
So, the answer is that with the given two sides and included angle, only one unique triangle can be drawn.
I need the answer for that ^
so the right answer is of option D.

what is the area of the base in the figure below? A cylinder with height 12and diameter 6
Answer:
[tex]9\pi[/tex]
Step-by-step explanation:
I don't see a picture, so I'm assuming the cylinder looks like a soup can sitting on a table, resting on it's circular base.
The base of the cylinder is a circle, so you need to find the area of a circle with diameter 6. Use the formula
[tex]A=\pi r^2[/tex] where r is the radius of the cylinder. If the diameter is 6, then the radius is 3.
[tex]A=\pi (3)^2 = 9\pi[/tex]

what two numbers multiply to -8 and add to -4
Answer:
-2-2√3, -2+2√3
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:
x(-4-x) = -8
-4x -x^2 = -8 . . . . . eliminate parentheses
x^2 +4x = 8 . . . . . . multiply by -1
x^2 +4x +4 = 12 . . . add 4 to complete the square
(x +2)^2 = 12
x +2 = ±√12 = ±2√3
x = -2±2√3
The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.
To find two numbers that multiply to -8 and add to -4, we can guess and check until we find a pair that satisfies both conditions. The two numbers in this case are -4 and 2.
Explanation:
The question is asking for two numbers that, when multiplied together, equal -8 and, when added together, equal -4. This falls under the category of quadratic equations. To solve this problem, we would typically use the formula "x = [ -b ± sqrt(b² - 4ac) ] / 2a", but in this case, it's easier to guess and check numbers. The two numbers that satisfy the conditions are -4 and 2. Their multiplication gives us -8 (-4*2) and their addition gives us -4 (-4+2).

B.If a is between 0 and 1, the image of the polygon is congruent to the polygon.
C.If a is greater than 1, the image of the polygon is smaller than the polygon.
D.If a is between 0 and 1, the image of the polygon is smaller than the polygon.
9514 1404 393
Answer:
D. If a is between 0 and 1, the image of the polygon is smaller than the polygon.
Step-by-step explanation:
The given transformation represents a dilation by a scale factor of 'a'. Every linear dimension of the image polygon will be a factor of 'a' times the corresponding dimension of the original.
When a > 1, the image is larger.
When a = 1, the image is congruent to the original (no sizes have changed).
When 0 < a < 1, the image is smaller. This description matches choice D.
The correct answer is D. If a is between 0 and 1, the image of the polygon is smaller than the original polygon.
Given that a polygon is graphed on a coordinate grid with (x, y) representing the location of a certain point of the polygon.
The polygon is transformed using the rule (x, y) → (ax, ay).
We need to determine the possible result of the transformation.
When a transformation rule (x, y) → (ax, ay) is applied to a polygon on a coordinate grid, the value of a determines the scaling factor of the image.
If a is greater than 1, the image of the polygon will be larger than the original polygon because the coordinates are multiplied by a value greater than 1, resulting in an expansion or enlargement of the shape.
If a is between 0 and 1, the image of the polygon will be smaller than the original polygon because the coordinates are multiplied by a value between 0 and 1, resulting in a contraction or reduction of the shape.
Therefore, statement D is correct.

One way to notate the complement of an event A is not A. For instance, suppose that P(even) represents the probability of rolling an even number on a number cube. Then, P(not even) represents the probability of rolling a number that is not even on a number cube.
Consider the events from Activity 1.1, Questions 5 and 6—“rolling an even number” and “rolling a number that is not even.” What do you notice about the sum of the probabilities of these two complementary events?
Sum is always 1
Step-by-step explanation:
Step 1: Find the sum of probability of complementary events.The sum of probability of an event and its complementary event is always 1.
Here, the event is rolling an even number. Let it be P(even)
Its complementary event is rolling a number that is not even. Let it be P(not even)
P(even) = 1/6
P(not even) = 5/6
P(even) + P(not even) = 1/6 + 5/6 = 1
What function is represented by the mapping diagram shown?
O A. F(x)= x+3
O B. F(x)= x-3
O C. F(x) = 3x
O D. F(x) = 1
The mapping diagram displays how inputs are transformed into outputs; this relationship must match the transformation properties of the given functions to determine the correct answer.
Explanation:To understand which function is represented by the mapping diagram, one needs to look at how the inputs (or arguments) are being transformed into outputs (or values). A mapping diagram shows a set of ordered pairs, illustrating how each input is associated with a specific output. Considering the functions given: F(x) = x+3, F(x) = x-3, F(x) = 3x, and F(x) = 1, it is important to note the nature of transformations that each of these functions imply.
For the F(x) = x+3 function, every input value x is increased by 3, which is a shift to the right on the graph. On the other hand, F(x) = x-3 would decrease every input x by 3, showing a leftward shift. If we consider F(x) = 3x, this would imply each input x is being scaled by a factor of 3. Lastly, F(x) = 1 represents a constant function that maps every input to the same output, which is 1.
To determine the correct function from the mapping diagram, one would compare these transformations to the mapping shown and select the function that accurately describes the relationship between the inputs and outputs in the diagram.

Alona has some wood cutouts of two different shapes - square and triangle. Each square cutout is 6 mm thick and each triangular cutout is 8 mm thick. Both cutouts have the same area of cross-section. Alona makes an upright stack using 24 square cutouts. She is making an oblique stack using the triangular cutouts. How many triangular cutouts should she put in the oblique stack so that both stacks have the same volume?
Answer:
18
Step-by-step explanation:
Volume is a product of cross-sectional area and height and relresented as V=Ah where V is volume, A is cross-sectional area and h is height.
For the square, since each has a thickness of 6mm then for 24 of them the height will be 24*6=144 mm
Since the volume and cross sectional area of the triangle should be the same, then the height should also be the same.
Since for the triangle each has a thickness of 8mm then the number requred to achieve a height of 144 mm will be 144/8=18 stacks
To find the number of triangular cutouts needed for the oblique stack to have the same volume as the upright stack, we need to compare the volumes of the two shapes. The volume of a square cutout is 6mm × (the area of the square cross-section), while the volume of a triangular cutout is 8mm × (the area of the triangular cross-section).
Explanation:To find the number of triangular cutouts needed for the oblique stack to have the same volume as the upright stack, we need to compare the volumes of the two shapes. The volume of a square cutout is 6mm × (the area of the square cross-section), while the volume of a triangular cutout is 8mm × (the area of the triangular cross-section).
Since both stacks have the same area of cross-section, we can set up the equation 6mm × (area of a square) × 24 = 8mm × (area of a triangle) × (number of triangular cutouts). By finding the ratio of the volumes and solving for the number of triangular cutouts, we can determine the number needed.

Does this graph represent constant or changing speed? How do you know?
Find the average speed (1pt).
Answer:
yes because the no's.are different and they are moving high in the graph
The graph represents changing speed, and the average speed is 0.5 meters per second.
To determine whether the graph represents constant or changing speed, we examine the relationship between distance and time.
If the speed remains consistent over time, the graph represents constant speed.
Conversely, if the speed varies, the graph represents changing speed.
Upon examining the data provided, we observe that the distance traveled increases as time progresses, indicating changing speed.
This inference arises because the increments in distance over successive time intervals are not consistent, suggesting acceleration or deceleration.
To find the average speed, we divide the total distance traveled by the total time taken. In this case, the total distance covered is 100 meters (from 10 to 100 meters), and the total time elapsed is 200 seconds (from 20 to 200 seconds).
Therefore, the average speed is:
[tex]\[ \text{Average speed} = \frac{\text{Total distance}}{\text{Total time}} = \frac{100 \, \text{m}}{200 \, \text{s}} = 0.5 \, \text{m/s} \][/tex]
Hence, the graph represents changing speed, and the average speed is 0.5 meters per second.
