The total volume of the silo is 116.6 m³.

It is a solid where a hemisphere is kept on top of a cylinder sharing common circular bases.

Diameter of the cylinder of the silo= 4.4m

So, the radius r of the cylinder will be = 2.2m

The radius r of hemisphere = 2.2m (same as cylinder due to common circular bases)

Height h of the cylinder = 6.2m

The total volume of the silo will be the combined volume of the cylinder and hemisphere.

The volume of cylinder = [tex]\pi r^{2} h[/tex]

The volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]

Total volume = [tex]\pi r^{2} h+ \frac{2}{3} \pi r^{3}[/tex]

total volume = [tex]\pi r^{2} (h+\frac{2}{3} r)[/tex]

Total volume = [tex]\pi *2.2^{2} (6.2+\frac{2}{3} *2.2)[/tex]

Total volume = 116.6 m³.

Therefore, the total volume of the silo is 116.6 m³.

Answer:

The volume of the 80% ammonia that is to be drained before water is added is 7.5 quartz

Step-by-step explanation:

The volume of the ammonia and water mixture = 5 gallons

The percentage of ammonia in the mixture = 80%

The volume of ammonia desired = 5 gallons

The percentage concentration of ammonia desired = 50%

The diluting solution = Pure water

The measure of 4 quarts = 1 gallon

Therefore, we have, by equivalence solutions;

80% × x gallon = 50% × 5 gallons

x gallon = 50% × 5 gallons/(80%) = 3.125 gallons

x = 3.125 gallons

The volume of the 80% ammonia that is to be drained = 5 gallons - 3.125 gallons = 1.875 gallons

4 quarts = 1 gallon

1 gallon = 4 quarts

∴ 1.875 gallons = 4 × 1.875 quartz = 7.5 quartz

The volume of the 80% ammonia that is to be drained before water is added = 7.5 quartz

Answer:

We add the two fractions:

6 3/8 + 7 2/5 = 13 31/40 boxes of candy bars.

Answer:

Add the two fractions 6 3/8 + 7 2/5 = 13 31/40

Step-by-step explanation:

First multiply the whole numbers by the denominator then add it to the numerator, then find the most common factor (in the denominators) which is 40 (8x5 and 5x8) and multiply the numerator by the same number as the denominator, you will get 255/40 and 296/40 add them then simplify then you will get 13 31/40, thank you.

Answer:

1.2

Step-by-step explanation:

How I would calculate it would be 10.80 divided by 9 or start timesing 1 with a decimal like 1.1 or 1.2.

but anyway 10.80 divided by 9=1.2 and if you just want to make sure then what is 1.2 x 9 it = 10.80

Here is my calculations for what is 1.20 x 9   

 1 . 20

       9

_________

 10   . 8 0  

Since there is no didget beside the 2 you would add a zero

since 9 x 2=18 you add a 1 for 1 x 9 =9 + 1=10 and there's your answer.

The product of the provided binomial numbers (9 t minus 4)(negative 9 t minus 4) is equal to the option B which is,

[tex]-81t^2+16[/tex]

Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,

[tex]p=a\times b[/tex]

Here, (a, b) are the real numbers.

The binomial given in the problem are,

[tex](9t-4)\\(-9t-4)[/tex]

Let the product of the above function is p. Thus,

[tex]p=(9t-4)\times(-9t-4)[/tex]

To find the product of these two binomials, multiply the first term of first binomial with both the terms of the second binomial.

Similarly, multiply the second term of first binomial with both the terms of second binomial. Thus,

[tex]p=9t(-9t-4)-4(-9t-4)\\p=-81t^2-36t+36t+16\\p=-81t^2+16[/tex]

Thus, the product of the provided binomial numbers (9 t minus 4)(negative 9 t minus 4) is equal to the option B which is,

The factorized form of the polynomial 6x³ – 12x² + 7x – 14 is (6x²+7)(x–2).

A factor of n is a number which when multiplied by another number gives us the number n.

In order to factorize the polynomial 6x³ – 12x² + 7x – 14, we need to take the common terms out of the given polynomial, therefore, the polynomial can be factorized as,

[tex]6x^3-12x^2+7x - 14 \\\\[/tex]

Taking the common term 6x² out from the first two terms, and then 7 from the next two terms, therefore, the polynomial can be written as

[tex]6x^3-12x^2+7x - 14 \\\\= 6x^2(x-2)+7(x-2)\\\\=(6x^2 +7)(x-2)[/tex]

Hence, the factorized form of the polynomial 6x³ – 12x² + 7x – 14 is (6x²+7)(x–2).

Step-by-step explanation:

Put the number of students that want to be a therapist AND have a fear of height (this would be 3) over the TOTAL amount of students in the sample, in this case it's 14.

so it's 3/14 and it doesn't simplify

Answer:

21%

Step-by-step explanation:

First we need to find the total amount of people that did the personality test. We can do that by adding all the numbers in the table

[tex]4+5+2+3=14\\[/tex]

now, to find the percentage of students that want to be a therapist and a fear of heights, we simply divide the number of students who fit that demographic by the total number of students

The equations secx+cosecy = 2, and sinx+cosy=k are trigonometry equations

The result of [tex]\frac {3k}4[/tex] is [tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]

The equations are given as:

secx+cosecy = 2, and sinx+cosy=k

Divide both equations

[tex]\frac{\sin(x) + \cos(y)}{\sec(x) + \csc(y)} = \frac k2[/tex]

Divide through by 2

[tex]\frac{\sin(x) + \cos(y)}{2[\sec(x) + \csc(y)]} = \frac k4[/tex]

Express sec and cosec as inverse ratios

[tex]\frac{\sin(x) + \cos(y)}{2[1/\cos(x) + 1/\sin(y)]} = \frac k4[/tex]

Take the LCM

[tex]\frac{\sin(y)\cos(x)[\sin(x) + \cos(y)]}{2[\cos(x) + \sin(y)]} = \frac k4[/tex]

Expand

[tex]\frac{\sin(y)\cos(x)\sin(x) + \sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]} = \frac k4[/tex]

Multiply through by 3

[tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]} = \frac {3k}4[/tex]

Rewrite as:

[tex]\frac {3k}4 =\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]

Hence, the result of [tex]\frac {3k}4[/tex] is [tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]
