Mrs. Jones decided to buy some pencils for her class. She bought 3 packages of pencils, and each package contained 44 pencils. There are 22 students in her class and she divided up the pencils so that each student had the same amount of pencils. If there were no pencils left over, how many pencils did each student get?
A. 6
B. 66
C. 2
D. 25
Answer:
A
Step-by-step explanation:
First, multiple 3 by 44 to find the number of pencils total. 3x44=132.
Then, divide 22 into 132. 132/22=6.
Therefore, each student received 6 pencils.

Volume of a right circular cone that has a height of 9. 5 m and a base with a circumference of 10 m
hi pls help answer this!
Answer:
363-138=-5x
Step-by-step explanation:
Let c = cost
We know that the total cost is $363:
363-??????
We also know that he spent $138 on parts:
363-138?????
And we are solving for the cost of labor per hour:
363-138=5x
We can use this equation to find the total cost of labor per hour.
Hence, your equation will be 363-138=5x
A grain silo is composed of a cylinder and a hemisphere. the diameter is 4.4 meters. the height of its cylindrical portion is 6.2 meters. a half-sphere is stacked on top of a cylinder. they both share a circular base. the cylinder has a height of 6.2 meters and the sphere has a diameter of 4.4 meters. what is the approximate total volume of the silo? use 3.14 for π and round the answer to the nearest tenth of a cubic meter. 37.1 m3 71.9 m3 116.5 m3 130.8 m3
The total volume of the silo is 116.6 m³.
What is a grain silo in this problem?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.

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]
What is the product?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]

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

if secx+cosecy = 2, and sinx+cosy=k evaluate 3k/4.
Need help ASAP!
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]
How to evaluate 3k/4The 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]

If a five-gallon mixture of fifty percent ammonia is desired, how many quarts of the mixture need to be drained before the water is added
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

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

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.
Answer=1.2
