Angle x and angle y are complementary. angle x is supplementary to a 128 angle.What are the measures of angle x and angle y?
Answer:
y = 38°
Step-by-step explanation:
If Angle x and angle y are complementary, then x + y = 90°
Also, if angle x is supplementary to a 128 angle, then x + 128° = 180°.
Solving the latter equation for x, we get x = 52°.
Therefore, by the first equation, x + y = 90° becomes 52° + y = 90°, yielding
y = 38°

what is the volume of the pyramid if the height is 215 and the base is 339
Final answer:
The volume of a pyramid with a height of 215 units and a square base of 339 units on each side is calculated using the formula V = (1/3)Bh, resulting in a volume of 1,304,688.67 cubic units.
Explanation:
To find the volume of a pyramid, we can use the formula V = (1/3)Bh, where B is the area of the base and h is the height of the pyramid. If the base is a square with each side being 339 units, then the area of the base (B) can be calculated as 339×339 square units. Given the height (h) of the pyramid is 215 units, the volume can then be calculated.
First, calculate the area of the base:
B = 339×339 = 114921 square units.
Then, use the volume formula by plugging in B and h:
V = (1/3)×114921×215 = 1,304,688.67 cubic units.
Therefore, the volume of the pyramid is 1,304,688.67 cubic units.

The dimensions of a triangle are multiplied by 1/4.The area
of the smaller triangle can be found by multiplying the area
of the original triangle by what number?
Please help
Thank you!
Answer:
1/16
Step-by-step explanation:
Area is the product of linear dimensions.
Suppose the area of the triangle is the product of two dimensions p and q*:
A = pq
Then the smaller triangle will have an area that is ...
A = (1/4p)(1/4q) = (1/4)²pq = (1/16)pq . . . . . . 1/16 of the original area
__
If each of the linear dimensions of the triangle is multiplied by 1/4, the area will be multiplied by (1/4)² = 1/16.
_____
* No doubt, you have learned the area formula for a triangle is ...
A = (1/2)bh
In the above, we might have p=1/2b and q=h. Or, there could be some other relationship between triangle dimensions and p and q.
Find the value of x and y. Round to the nearest hundredth (2 decimal places)
To find the values of x and y requires solving equations, refining the solution through iterative methods like the extended Newton-Raphson technique, and validating results with approximation checks.
Explanation:In answering this mathematical question, we are attempting to find specific values for the variables x and y. To solve for these variables, we employ various mathematical methods such as the Newton-Raphson technique for refinement.
Keeping the referenced data in consideration, the equations provided reveal that we manipulate these equations to gradually reach a more accurate result. For instance, taking the quadratic equation y²-0.30068y +0.022500 = 0 and using the quadratic formula y = 0.30068 ± √(0.30068)² – (4)(1)(0.022500) allows us to find the value for y, and an iterative process enhances the precision of x and y.
Remember to always retain a few extra significant figures to minimize rounding errors in the computational process. Additionally, entering our data into a calculator or a computer program will help in writing the linear equation, which needs to be rounded to an appropriate number of decimal places for accuracy. Examples mentioned illustrate evaluating the coordinates of a point, substituting values into equations, and analyzing the relation between variables through a graphical approach.
To validate our results, we compare the approximation to the actual value to ensure that our error margin is acceptable, especially when dealing with extrapolations from implicit differentiation in calculus contexts.

A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)
The area of flying disk is 452.16 square centimeters
Step-by-step explanation:
The disc is in circular shape so we will use the formulas for circle in this question.
Given
Circumference = C = 75.36 centimeters
We have to find the area of the disc for which we have to find the radius first.
Let r be the radius
Then
Circumference is given by:
[tex]C=2\pi r[/tex]
putting the values
[tex]75.36 = 2*3.14*r\\75.36 = 6.28r[/tex]
Dividing both sides by 6.28
[tex]\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm[/tex]
The area of circle is given by:
[tex]A = \pi r^2[/tex]
Putting the values
[tex]A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2[/tex]
Hence,
The area of flying disk is 452.16 square centimeters

What is its volume?
Answer:
Step-by-step explanation:

To find the volume of a cube with a given surface area, we can use the formula for surface area and rearrange it to find the side length. Once we have the side length, we can calculate the volume of the cube.
Explanation:To find the volume of a cube, we need to determine the length of one side. Since a cube has 6 equal sides, we can calculate the length of each side using the formula for surface area: surface area = 6 * side length * side length. Let's rearrange the formula to find the side length: side length = sqrt(surface area / 6). Once we have the side length, we can calculate the volume using the formula: volume = side length * side length * side length. Plugging in the given surface area of 6534 square feet, we find that the volume of the cube is approximately 2314 cubic feet.

Answer:
Slope, m = [tex]$ \frac{\textbf{-2}}{\textbf{3}} $[/tex].
Step-by-step explanation:
The slope of the line can be determined by simplifying the given equation to its standard form.
In the standard form, y = mx + c, m represents the slope of the line.
We are given: [tex]$ y - 2 = - \frac{2}{3}(x + 1) $[/tex]
[tex]$ \implies y = -\frac{2}{3}x - \frac{2}{3} + 2 $[/tex]
[tex]$ \implies y = - \frac{2}{3}x + \frac{(-2 + 6)}{3} $[/tex]

Jerry is building an indoor beach volleyball court.
He has ordered 14,000 cubic feet of sand.
The dimensions of the court will be 30 feet by 60 feet.
Jerry needs to have a 10-foot boundary around the
court for safety. Be a math detective and determine
how deep the sand will be if Jerry uses all the sand.
Answer:
The deep of the sand will be 3.5 feet
Step-by-step explanation:
step 1
Find out the area of the court plus a 10-foot boundary around the court for safety
[tex]A=(30+10+10)(60+10+10)\\A=(50)(80)\\A=4,000\ ft^2[/tex]
step 2
Find the deep of the sand
we know that
The volume of the sand is equal to
[tex]V=Ah[/tex]
where
A is the area of the base
h is the height or deep of the sand
substitute the given values
[tex]14,000=(4,000)h[/tex]
Solve for h
[tex]h=14,000/4,000=3.5\ ft[/tex]
Jerry's indoor beach volleyball court, including a 10-foot boundary, would have an area of 4,000 square feet, and with 14,000 cubic feet of sand, it would result in the sand being 3.5 feet deep.
Explanation:Since Jerry wants to build an indoor beach volleyball court with a 10-foot boundary around it and has ordered 14,000 cubic feet of sand, we need to calculate the volume of the sand to determine how deep it will be when spread evenly over the entire area, including the boundary. The dimensions of the volleyball court are 30 feet by 60 feet, and adding a 10-foot boundary around it increases each dimension by 20 feet (10 feet on each side), resulting in a total area dimension of 50 feet by 80 feet.
To calculate the depth of the sand, we first calculate the area of the court including the boundary: Area = length × width = 50 feet × 80 feet = 4,000 square feet. Next, we divide the total amount of sand by the area to find the depth: Depth = volume / area = 14,000 cubic feet / 4,000 square feet = 3.5 feet deep. Therefore, if Jerry uses all the sand, it will be 3.5 feet deep.

Given the sequence 2, 4, 8, , 16,........, where x = 0, 1, 2, 3, .......what is the function rule? f(x) = 2x + 2 f(x) = 2(2)x f(x) = (2x) f(x) = 2
f(x) = 2([tex]2^{x}[/tex])
Step-by-step explanation:
Step 1 :
Given
When x =0, f(x) = 2
x =1, f(x) = 4
x =2, f(x) = 8
x =3, f(x) = 16
Step 2 :
Substituting for x in the function f(x) = 2([tex]2^{x}[/tex]) we get,
When x =0, f(x) = 2
x =1, f(x) = 4
x =2, f(x) = 8
x =3, f(x) = 16
This matches the given sequence and this shows that the function represents the given sequence .
Final answer:
The function rule for the given sequence 2, 4, 8, 16, ... is [tex]f(x) = 2^x[/tex], representing the sequence's exponential growth pattern where each term is double the previous term.
Explanation:
The given sequence is 2, 4, 8, 16, ..., which is a geometric sequence where each term is multiplied by 2 to get the next term. This pattern corresponds to an exponential function where the base is 2 and the exponent is the position of the term, which can also be thought of as the function's input, x. Therefore, the function that represents this sequence is f(x) = 2x.
The other function choices given, such as f(x) = 2x + 2 or f(x) = 2, do not correctly represent the pattern observed in the sequence. The correct function rule for the given sequence is f(x) = 2x which fits the pattern where when x is substituted for each term's position (starting from 0), the function provides the corresponding term of the sequence.

Yo sup??
Equation of the given line is
y=12 - 0.5x
on the y axis the x coordinate will be , therefore at x=0 we get
y=12 - 0.5*0
y=12
Therefore the coordinates of the y intercept are (0,12).
Hope this helps.
Final answer:
The y-intercept for the equation y = 12 - 0.5x is found by setting x to 0, resulting in y = 12, giving us the coordinates of the y-intercept as (0, 12).
Explanation:
The equation of a straight line is given by y = mx + b, where m represents the slope of the line, and b is the y-intercept. In your case, the equation is y = 12 - 0.5x. To find the coordinates of the intercept on the y-axis, we set x to 0 and solve for y. This gives us the y-intercept directly from the equation without needing to graph it.
For the equation y = 12 - 0.5x, when x = 0:
y = 12 - 0.5(0)
y = 12 - 0
y = 12
Therefore, the coordinates of the intercept on the y-axis are (0, 12).

96 m
2 m/sec²
Step-by-step explanation:
Step 1:
In a velocity and time graph , the area which is under the plotted line represents the distance traveled
In the given graph , the plotted line from t=0 to t=4 ( for the first 4 secs) is a triangle with base = 4 and height = 8
Area of this triangle is (1/2) * b * h = (1/2)* 4*8 = 16 m
Step 2 :
The plotted line from t = 4 to t = 14 is a rectangle with length equal to 10 and breadth equal to 8
Hence its area = length * breadth = 10 * 8 = 80 m
Step 3 :
Total distance traveled is 80 + 16 = 96 m
Step 4 :
In the velocity time graph , slope denotes the acceleration at any given time. Since we want the acceleration for the first 4 secs, we need to find slope of line in from t = 0 to t= 4
when t = 0, v =0 and t= 4, v = 8
Slope = 8-0/4-0 =2 m/sec²
