The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4
Let 3x and 4x are the seeds from the smaller and bigger pile.
= 4x + 2 (greedy hamster placed another 2 pounds of seeds in the bigger pile)
= 3x - 1/4 (ate 1/4 pound from the smaller pile)
4x + 2 = 5x
Because the quantities of seeds in those piles is in the ratio of 5:16
After solving:
x = 2
Smaller pile weight = 3x = 3(2) = 6
Bigger pile wieght = 4x = 4(2) = 8
Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

For the given functions f and g find f•g and state it’s domain
f(x) = 3x - 6; g(x) = 8x +4
The function is (c) (f.g)(x) = 24x^2 - 36x - 24; domain of all set of real numbers
How to determine the composite functions?The given parameters are:
f(x) = 3x - 6; g(x) = 8x +4
The composite function is calculated as:
(f.g)(x) = f(x) * g(x)
This gives
(f.g)(x) = (3x - 6) * (8x + 4)
Expand
(f.g)(x) = 24x^2 + 12x - 48x - 24
Evaluate the difference
(f.g)(x) = 24x^2 - 36x - 24
The above function is a quadratic function;
Quadratic functions have a domain of all set of real numbers
Hence, the function is (c) (f.g)(x) = 24x^2 - 36x - 24; domain of all set of real numbers

Does anyone know how to do this?
For all rectangles, the area is the length multiplied by the height. For squares (a special type of rectangle), the length and height are the same, so you just use [tex]s^2[/tex], where [tex]s[/tex] is the side length.
[tex]A=s^2=16^2=\boxed{256}[/tex]
(b) The circleThe formula for the area of the circle is [tex]\pi r^2[/tex], where [tex]\pi[/tex] is pi, a constant, and [tex]r[/tex] is the radius of the circle, or the length from the center point to the edge.
We're given the side length of the square, which is the same as the diameter of the circle (length from edge to edge going through the center point). Divide the diameter by [tex]2[/tex] to get the radius of [tex]8[/tex] kilometers.
[tex]A=\pi r^2=\pi8^2=\boxed{64\pi}\approx201.1[/tex]
(c) The blue sectionThe area of the blue section is simply the area of the square minus the area of the circle since we just want what's left over.
[tex]A=\boxed{256-64\pi}\approx54.9[/tex]
You can keep the answer exact (the boxed expression) or use the approximate value of 54.9, depending on the instructions for the assignment.

Find the height of the triangle by applying formulas for the area of a triangle and your knowledge about triangles.
This is a triangle. side a has a length of 12 inches. side b has a length of 12 inches. side c has a length of 8 inches. The altitude to side c has a length of X inches.
Using the Pythagorean Theorem, the altitude to side c has a length of 11.3 inches.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
To find the altitude relative to side c, we bisect this side, which cuts it's length into half(now of 4 inches), forming a right triangle in which:
The altitude is the other leg.The side of 12 inches is the hypotenuse.Hence:
[tex]x^2 + 4^2 = 12^2[/tex]
[tex]x = \sqrt{12^2 - 4^2}[/tex]
x = 11.3 inches.

Volume and surface area
Answer:
The 1st one is 540π
The 2nd one is 1696.46
Step-by-step explanation:
To find the volume of a cylinder, you do the following:
[tex](r)^2\pi \times h[/tex]
Where r represents the radius of the circle and h represents the height. Because it's multiplication, we can change it to:
[tex]r^2\times h \times \pi[/tex]
So since the radius is 6, 6^2 is 36. Then we multiply by 15, to get 540. Then now since we don't need to multiply the pi, you just leave it as 540π.
For the second one, multiply 540 by pi to get the answer, then round it to the nearest hudredth to get 1696.46.

The swimming pool at Spring Valley High School is a rectangle with a width of 70 meters and a length of 30 meters. Around the perimeter of the pool is a tiled floor that extends w meters from the pool on all sides. Find an expression for the area of the tiled floor.
The expression that can be used to find the area of the tiled floor is 4w² + 200w
Area of rectangleOriginal rectangle:Length = 70 Meters
Width = 30 meters
Area = length × width
= 70 × 30
= 2100
New rectangle(including tiled floor):Length = 70 + 2w meters
Width = 30 + 2w meters
Area = length × width
= (70+2w) (30+2w)
= 2100 + 140w + 60w + 4w²
= 4w² + 200w + 2100
Area of the tiled floor = Area of new rectangle - area of old rectangle
= (4w² + 200w + 2100) - 2100

This exercise is about Linear Functions. From the values given, we can state that:
The value of missing x = 6The value of missing y = 21 (Option D)What is the explanation for the above?Given that the table represents a linear function, so the function is a straight line.
Taking two points
(-12, 17)
(-10, 19)
To determine the slope between (-12, 17) and (-10, 19), we need to use the formula:
Slope = (y2-y1)/(x2 - x1)
Recall that:
(x1, y1) = (-12, 17); and
(x2, y2) = (-10, 19)
m = 19 -17/-10 -17
m = 1
Leveraging the point-slope to create the linear equation, we have:
y-y1 = m(x-x1)
where m is the slope of the line and (x₁, y₁) is the point substituting the values m = 1 and the point (-12, 17). Hence, we have:
y-y1 = m(x-x1)
→ y-17 = 1 (x-(-12))
→ y - 17 = x +12
y = x + 12 + 17
y = x + 29 ..................................Linear Equation
Next, we substitute x = -8 into the Linear Equation
y = (-8) + 29
y = 21
Hence, the missing y = 21; and
The missing x = -8
If we substitute y = 23 into the equation, we have:
y = x + 29
23 = x + 29
x = 29 - 23
x = 6
Thus, when the value of y = 23, the missing x is = 6
Conclusively,
The value of missing x = 6
The value of missing y = 21
