the exact volume is what?
Answer:
7680πyd³
Step-by-step explanation:
The formula to calculate the volume of the cylinder is πr² h
Here radius (r) = 16 yd
height (h) = 30 yd
Now
the volume is
= πr²h
= 16² * 30 * π
= 7680 π yd³

Terell jackson opened a savings account by depositing his $1,050 paycheck his bank pays 12% interest compound a monthly basis he doesn't make any other deposits or withdrawals after three years how much interest will he earn
Answer:
Interest= $516.93
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $1,200
Number of periods (n)= 12*3= 36 months
Interest rate (i)= 0.12/12 = 0.01 monthly
First, we need to calculate the future value of the investment using the following formula:
FV= PV*(1 + i)^n
FV= 1,200*(1.01^36)
FV= $1,716.93
Now, the interest earned:
Interest= 1,716.93 - 1,200
Interest= $516.93

The length of a rectangle is 7 cm longer than it's width, x cm. So, write down an equation in term of x, for the length of this rectangle
Answer:
Length = (7 + x)
Step-by-step explanation:
In this question we have to convert the verbal expression to algebraic expression.
Let the width of the rectangle = x cm
"Length of the rectangle is 7 cm longer than it's width"
Length = 7 + Width
Length = (7 + x) cm
Therefore, equation for which length of the rectangle is defined will be,
Length = (7 + x)
in a random School sampling of 50 middle school students it was found that 18 students bring their lunch to school everyday if there are 942 students in the school predict how many bring their lunch to school each day
Answer:
340
Step-by-step explanation:
We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.
0.36*942= 339.12 which we can round to 340

The total number of animals in a shelter is modeled by f(x) = 2x2 - 45x, where x represents the number of
cages at the facility. How many cages are at the facility if it has a total of 243 animals there?
A. 25
B. 27
C. 33
D. 39
Answer:
B: 27
Step-by-step explanation:
The total number of animals in a shelter is modeled by the function:
[tex]f(x)=2x^2-45x[/tex]
Where x is the number of cages at the facility.
We want to determine the number of cages if there are a total of 243 animals at the shelter.
So, we can set our function to 243 and solve for x:
[tex]243=2x^2-45x[/tex]
Subtract 243 from both sides:
[tex]2x^2-45x-243=0[/tex]
Solve the quadratic. Factoring and completing the square seems too difficult, so we can use the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
In this case, a = 2, b = -45, and c = -243. Substitute:
[tex]\displaystyle x=\frac{-(-45)\pm\sqrt{(-45)^2-4(2)(-243)}}{2(2)}[/tex]
Evaluae:
[tex]\displaystyle x=\frac{45\pm\sqrt{3969}}{4}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{45\pm63}{4}[/tex]
Therefore, our two solutions are:
[tex]\displaystyle x=\frac{45+63}{4}=27\text{ or } x=\frac{45-63}{4}=-\frac{9}{2}[/tex]
Since we cannot have negative or half a cage, we can ignore the second solution.
Therefore, there are a total of 27 cages at the shelter.
Our answer is B.
Answer:
B. 27 is the answer.

1) Find the missing side.
Answer:
25inch
Step-by-step explanation:
Ok so there is something called a Pythagorean theorem.
It's a²+b²=c²
It works on right triangles
C is the longest side or the side not touching the right angle
and a and b is the other 2 sides
so the missing side is 24²+7²=Missing side or c²
24²=576 and 7²= 49

Which algebraic expression is equivalent to the expression below? 6x+15y A. 3(2x - 5y) B. 3(5x - 2y) C. 3(2x + 5y) D. 3(5x + 2y)
Answer:
C. 3(2x + 5y) is the algebraic expression equivalent to the expression
Step-by-step explanation:
From the question, the given expression is 6x + 15y.
Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).
Checking the remaining options
A. 3(2x - 5y)
Expanding this gives 6x - 15y. It is not equivalent to the given expression
B. 3(5x - 2y)
Expanding this gives 15x - 6y. It is not equivalent to the given expression
D. 3(5x + 2y)
Expanding this gives 15x + 3y. It is not equivalent to the given expression.
Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.
the universal set = {-4, -3, -2, -1, 0 , 1, 2, 3, 4} and A = {0}. what is the complement of A?
The complement of a set are the set of elements in the universal set but not in the original set. The complement of set A is: [tex]A' = \{-4, -3, -2, -1, 1, 2, 3, 4\}[/tex]
Given that:
[tex]A =\{0\}[/tex]
[tex]U = \{-4, -3, -2, -1, 0 , 1, 2, 3, 4\}[/tex]
The complement of set A are the set of elements in the universal set but that are not in set A.
So, the complement of set A is:
[tex]A' = \{-4, -3, -2, -1, 1, 2, 3, 4\}[/tex]

what are the coordinates of point B on AC such that the ratio of AB to BC is 2:3
The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).
What are the coordinates of a point within a line segment?
In this problem we must use the concept of segment ratios and linear algebra operations to determine the location of a point within a line segment generated by two distinct points:
B(x, y) = A(x, y) + (AB / AC) · [C(x, y) - A(x, y)]
B(x, y) = (0, 4) + (2 / 5) · [(6, 13) - (0, 4)]
B(x, y) = (0, 4) + (2 / 5) · (6, 9)
B(x, y) = (0, 4) + (12 / 5, 18 / 5)
B(x, y) = (12 / 5, 38 / 5)
The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).
RemarkThe statement is incomplete, complete form is shown below:

If two lines are parallel and they are defined by the equations, y=4x-5 and y=ax+2, what is the value of a?
Answer:
[tex]a=\dfrac{4x-7}{x}[/tex]
Step-by-step explanation:
The equations of lines are :
y=4x-5 and y=ax+2
From above equations,
4x-5 = ax+2
4x-ax = 5+2
4x-7 = ax
[tex]a=\dfrac{4x-7}{x}[/tex]
So, the value of a is equal to [tex]\dfrac{4x-7}{x}[/tex].
3) Bella recorded data and used her graphing calculator to find the equation for
the line of best fit. She then used the correlation coefficient to determine the
strength of the linear fit. Which correlation coefficient represents the strongest
linear relationship?
-0.9
0.3
-0.5
0.8
Answer:
-0.9
Step-by-step explanation:
my guess
it's supposed to be the a number closest to 1 or-1
so
-0.9 is the closest number to 1 or -1
The answer to this question is:
0.8
What is line of best fit and correlation coefficient?
A straight line that best approximates the given set of data is known as a line of best fit. It is a line that, on a graph, roughly straddles the center of each scatter point. The association is stronger the closer the points are to the line of greatest fit.
The equation of a line of a best fit is represented as: y=mx + c
To gauge how closely two variables are related to one another, correlation coefficients are used.
Solution:
In order to determine how closely related two sets of data are, correlation coefficient formulas are used. The formulas provide a value in the range of -1 and 1, where
1 denotes a strongly positive association.A score of -1 indicates a very adverse association.A result of zero means there is absolutely no associationThe strength of the link between the variables increases with the distance between the coefficients of +1.0 and -1.0.
-0.9 is a value which is greater than -0.8, so the values which are greater than -0.8 are not considered as strong correlation coefficient.
Whereas the values which are less than 0.8 are also not considered as strong coefficients.
Hence 0.8 is the correlation coefficient which represents the strongest linear relationship.
