Answers
Answer:
The speed of a car is x miles per hour.
The total distance the car travels in
30 minutes is y. ....>>> y = 0.5x
The cost to produce a table, y, is two
times the cost to produce a chair, x. ..> y = 2x
The time required to bake a chocolate
muffin, y, is 2 minutes more than the
time required to bake a vanilla muffin, x.....>> y = x + 2
Tina’s age, y, is 5 years more than
her brother Tim’s age, x. .......>> y = x + 5
Step-by-step explanation: The only really tricky one is the "speed of the car ..." because the speed is given in miles per hour and the time is given in minutes so that is 0.5 hour times time
Otherwise, "times" means multiplication and "more than" means addition.
HELPP (ESPECIALLY PART B) Answer the questions in this part of the task based on your understanding of the definition and the standard equation for the conic you chose. part a Inspect the equation for the type of conic section you chose. What attributes are necessary to graph it? Be sure to include specific points or equations to complete your answer. part b Explain how, if you have the attributes given below for the conic you chose, you can derive its equation in standard form.
Answers
The conic section chosen is a parabola, and the attributes for graphing of
a parabola as well as the standard form of the equation are as follows;
Part A: The attribute necessary to graph the equation of the parabola are three points, including, the vertex, the y-intercept and the image of the reflection of the y-intercept across the axis of symmetry.Part B: The equation in standard form is x = -0.25·y² + y + 3Reasons:
Part A:
The equation of the conic section of a parabola is; (x - 3)² = 12·(y - 2)
The vertex form of the equation of a parabola is; y = a·(x - h)² + k
Where (h, k) = The vertex
Rearranging the given equation gives;
(x - 3)² = 12·y - 24
12·y - 24 = (x - 3)²
12·y = (x - 3)² + 24
\(\displaystyle y = \frac{1}{12} \cdot \left(x - 3\right)^2 + \frac{24}{12} = \frac{1}{12} \cdot \left(x - 3\right)^2 + 2\)
\(\displaystyle y = \frac{1}{12} \cdot \left(x - 3\right)^2 + 2\)
Therefore, the vertex of the parabola, (h, k) = (3, 2)
At the y-intercept, x = 0, which gives;
\(\displaystyle y = \frac{1}{12} \cdot \left(0 - 3\right)^2 + 2 = \frac{9}{12} + 2 = 2+\frac{3}{4}\)
\(\displaystyle y = 2+\frac{3}{4} = 2.75\)
The y-intercept = (0, 2.75)
The x-intercept is given at the point where y = 0, which gives;
(x - 3)² = 12·(0 - 2) = -24
x - 3 = √(-24) = An imaginary number
Therefore, the graph has no x-intercept
Given that a parabola is symmetrical about the vertex, we have a third
point on the parabola at the image of the y-intercept reflected across the
axis of symmetry as follows;
The y-intercept (0, 2.75) is 3 units to the left of the axis of symmetry, x = 3,
therefore, the third point will be 3 units to the right of the axis of symmetry
at the point (3 + 3, 2.75) = (6, 2.75)
Therefore, using the three points, (0, 2.75), (3, 2), and (6, 2.75), the curve
representing the parabola, (x - 3)² = 12·(y - 2), can be drawn.
Please find attached the graph of the parabola created with MS Excel
Part B; Given the attributes of the parabola; Vertex: (4, 2) and focus: (3, 2), we have;
The focus of a parabola is the point (h + p, k)
Where, (h, k) = The vertex
Therefore, by comparison, we have;
(h, k) = (4, 2)
h + p = 3
Therefore;
4 + p = 3
p = 3 - 4 = -1
The vertex form of the equation of the parabola is; (y - k)² = 4·p·(x - h)
Therefore, we get;
(y - 2)² = 4 × (-1) × (x - 4) = -4·(x - 4)
y² - 4·y + 4 = 16 - 4·x
4·x = 16 - (y² - 4·y + 4) = -y² + 4·y + 12
Which gives, the standard form as follows;
\(\displaystyle x = -\frac{y^2}{4} + y + 3 = -0.25 \cdot y^2 + y + 3\)
Standard form of the the equation of the parabola; x = -0.25·y² + y + 3Learn more about the graph of a parabola here:

Step-by-step explanation:
it has to add up to 360 degrees
so 111 + 111 = 222 since those two angles are the same
then 360 - 222 so you get the sum of the two smaller angles
which is 138
and 138/2 is 69
Answer: 69
Step-by-step explanation: 111 + 111 = 222
360 - 222 = 138

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answers
Answer:
0.32 (rounded to the nearest hundredth)
Step-by-step explanation:
If you have any questions ask me please! :)
Answer:
0.32 km
Step-by-step explanation:
Using the formula r = c / (2 * π), where c = 2 kilometers and π = 3.14, we can calculate the radius as:
r = 2 km / (2 * 3.14)
r = 2 km / 6.28
r = 0.31847133758 km
Rounding this to the nearest hundredth gives:r ≈ 0.32 km
Therefore, the approximate radius of the circle is 0.32 kilometers.

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answers
Answer:
I. Length: 43 inches
II. Width: 15 inches
III. Height: 5.5 inches
Step-by-step explanation:
To determine the dimensions of the new box, we need to calculate the space required for a dozen donuts lying flat, including the additional space of one inch.
Since the diameter of each donut is 3.5 inches, the width of the box must be greater than or equal to 3.5 x 4 = 14 inches to accommodate four donuts placed side by side.
Similarly, since the height of each donut is 1.5 inches, the height of the box must be greater than or equal to 1.5 x 3 = 4.5 inches to accommodate three donuts stacked on top of each other.
Finally, since the length of each donut is 3.5 inches, the length of the box must be greater than or equal to 3.5 x 12 = 42 inches to accommodate a dozen donuts lying flat.
Adding one inch to each dimension gives us a final box size of:
Length = 42 + 1 = 43 inches
Width = 14 + 1 = 15 inches
Height = 4.5 + 1 = 5.5 inches
Therefore, the dimensions of the new box should be:
I. Length: 43 inches
II. Width: 15 inches
III. Height: 5.5 inches

HELP NEEDED NOW Measure the difference between the lower quartile of Data Set A and the lower quartile of Data Set B. Round to the nearest tenth when performing all operations.
Answers
Answer:
29
Step-by-step explanation:
The formula for lower quartile(Q1) = 1/4(n + 1)th term
Where n = number of terms.
For Data set A = 73, 75, 79, 81, 84, 85, 86, 86, 89, 91, 94, 95
n = 12
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(12 + 1) th term
Q1 = 1/4(13) th term
Q1 = 3.25th term
The 3.25th term is data set A is between the 3rd and 4th term
3rd term = 79
4th term = 81
3.25th term = 79 + 81/2
= 160/2
= 80
For Data set B = 47, 49 , 51, 51, 55, 56, 57, 58, 59, 59, 61, 62
n = 12
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(12 + 1) th term
Q1 = 1/4(13) th term
Q1 = 3.25th term
The 3.25th term is data set A is between the 3rd and 4th term
3rd term = 51
4th term = 51
3.25th term = 51 + 51/2
= 102/2
= 51
The difference between the lower quartile of Data Set A and Data Set B =
80 - 51 = 29
