Answer:
7 : 5 : 2
Step-by-step explanation:
The ratio is reduced by dividing by the greatest common factor. Since you know your multiplication tables, you know each of the numbers is a multiple of 8. When you divide that out, you get the reduced form.
56 : 40 : 16 = 56/8 : 40/8 : 16/8 = 7 : 5 : 2

plz someone help I will mark brainlest diameter is 8.8 yd
Answer:
60.79 square yards.
Step-by-step explanation:
d = 2r; d = 8.8.
8.8 = 2r
r = 8.8 / 2
r = 4.4 yards.
Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.
4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.
Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

Find the third term in the expansion of (a+b)^9 in the simplest form
Answer:
[tex]The\ third\ term\ is\ \boxed{36a^7b^2}\\[/tex]
Step-by-step explanation:
[tex]\left(\begin{array}{c}9\\ 1\end{array}\right)=\dfrac{9}{1} =9\\\\\left(\begin{array}{c}9\\ 2\end{array}\right)=\dfrac{9*8}{2*1} =36\\\\\\(a+b)^9=a^9+\left(\begin{array}{c}9\\ 1\end{array}\right)a^8b+\left(\begin{array}{c}9\\ 2\end{array}\right)a^7b^2+....+b^9\\\\\\The\ third\ term\ is\ \boxed{36a^7b^2}\\[/tex]
The given expression is:
[tex](a+b)^9[/tex]According to the question,
→ [tex]\binom{9}{1} = \frac{9}{1}[/tex]
[tex]= 9[/tex]
→ [tex]\binom{9}{2} = \frac{9\times 8}{2\times 1}[/tex]
[tex]= \frac{72}{2}[/tex]
[tex]= 36[/tex]
Now,
→ [tex](a+b)^9 = a^9+\binom{9}{1}a^8b+\binom{9}{2}a^7b^2+...+b^9[/tex]
hence,
The third term is "[tex]36a^7b^2[/tex]".
Thus the approach above is appropriate.

Find the volume of the following solid. Using cylindrical coordinates
z = 4 - 4(x^2 + y^2)
z = (x^2 + y^2)^2 -1
In cylindrical coordinates, the equations of the surfaces become
[tex]z = 4 - 4r^2 \\\\ z = (r^2)^2 - 1 = r^4 - 1[/tex]
These surfaces intersect on the cylinder of radius 1 with cross sections parallel to the x,y-plane:
[tex]4 - 4r^2 = r^4 - 1 \\\\ \implies r^4 + 4r^2 - 5 = (r-1)(r+1)(r^2+5) = 0 \\\\ \implies r=1[/tex]
Then in cylindrical coordinates, the volume of the space bounded by these surfaces is
[tex]\displaystyle \int_0^{2\pi}\int_0^1\int_{r^4-1}^{4-4r^2}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta = 2\pi \int_0^1 \int_{r^4 - 1}^{4-4r^2}r\,\mathrm dz\,\mathrm dr \\\\ = \pi \int_0^1 (4-4r^2)^2 - (r^4-1)^2 \,\mathrm dr \\\\ = \pi \int_0^1 (15-32r^2+18r^4-r^8)\,\mathrm dr = \boxed{\frac{352\pi}{45}}[/tex]

Answer and Step-by-step explanation:
This graph is a One to One Function.
For a function to be one-to-one, each x value must have its own y-value, which is the case for this graph.
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If you draw a vertical line on the graph, and it intersects more than once, then the graph does not define as a function because that x value has more than one output (y).

The ratio of qualified teachers to unqualified teachers is 1;2. Use the given ratio and determine how many qualified teachers there are if there are 540 unqualified teachers. show your calculations
Answer:
270
Step-by-step explanation:
by using the proportion rule:
let X be the number of qualified teachers then
1:2=X=540 i.e.
1/2 = X/540
by cross multiplication,
540x1=2xX
540=2X i.e.
X=540/2
X=270
There are 270 qualified teachers.
To solve this, we would apply the knowledge of proportion.
It is simply a way of stating that two ratios are of equal measure.
For example, [tex]a:b = x:y[/tex] or [tex]\frac{a}{b} = \frac{x}{y}[/tex]
Applying the following proportion rule given that:
Ratio of qualified teachers to unqualified teachers is 1:2.
Number of unqualified teachers = 540
Let number of qualified teachers be represented by x.
Therefore:
[tex]\frac{1}{2} = \frac{x}{540}[/tex]
Cross multiply
[tex]2x = 540(1)[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} = \frac{540}{2} \\x = 270[/tex]
Therefore, the number of qualified teachers is 270.

A corn refining company produces corn gluten
cattle feed at a variable cost of $82 per ton. If fixed costs are $120,000 per month and the feed sells for $134 per ton, how many tons must be sold each month for the company to have a monthly profit of $560,000?
With explaining pleaseee:)
The amount of tons that must be sold each month for the company to have a monthly profit is 13,076.923 tons per month
Let x represent the amount of tons sold each month
Hence,
560,000=134x-(82x+120,000)
Remove the bracket
560,000=134x-82x-120,000
560,000=52x-120,000
52x=560,000+120,000
52x=680,000
Divide both side by 52
x=680,000/52
x=13,076.923 tons per month
Inconclusion The amount of tons that must be sold each month for the company to have a monthly profit is 13,076.923 tons per month.
