A company makes cones out of solid foam. Each cone has a height of inches, and its base has a radius of inches. How much foam is needed to make cones? Use for , and do not round your answer.
Answer:
[tex]Amount = 55440in^3[/tex]
Step-by-step explanation:
Given [Missing piece]
[tex]h = 9in[/tex] --- height
[tex]r = 7in[/tex] --- radius
[tex]n = 120[/tex] --- number of cones
Required
How much foam for 120 cones
First, calculate the volume of 1 cone
[tex]V = \frac{1}{3}\pi r^2h[/tex]
[tex]V = \frac{1}{3} * \frac{22}{7} * 7^2 * 9[/tex]
[tex]V = \frac{1}{3} * 22 * 7 * 9[/tex]
[tex]V = 22 * 7 * 3[/tex]
[tex]V = 462in^3[/tex]
So, the amount of foams needed for 120 is:
[tex]Amount = 120 * V[/tex]
[tex]Amount = 120 * 462in^3[/tex]
[tex]Amount = 55440in^3[/tex]

In y=mx+b form
Answer:
y = 3x + 3
Step-by-step explanation:
m = 3 because the slope rises 3 and runs 1, therefore 3/1 = 3
b = 3 because the y-intercept is (0,3), therefore y-int = 3

Step-by-step explanation:
If me and my husband want to save 75000 over the next 13 years and I make 25 dollars and hour and he makes 12 dollars an hour how do I write this in a word problem involving a system of equations
Answer:
The general form of the equation is;
25·x + 12·y = 75,000
x + y ≤ 6,250
When they work the same duration, the time the husband and wife works is approximately 2,071 hours each
When they contribute the same amount, the wife, works for x = 1,500 hours, while the husband works for y = 3,125 hours
Step-by-step explanation:
The amount the couple intends to save in 13 years = $75,000
The amount the wife makes per hour = $25
The amount the husband makes per hour = $12
The number of working hours in 13 years is given as follows;
Total number of hours = 40 hr/week × 52 weeks/year × 13 years = 27,040 hours
However, when the husband alone works, we have;
75,000/12 = 6,250 hours
Let 'x' and 'y' represent the number of hours the wife and husband works respectively, we have the following system of equations;
The general form of the equation is;
25·x + 12·y = 75,000
x + y ≤ 6,250
When the couple work equal times
25·x + 12·y = 75,000...(1)
x = y...(2)
From equation (1), we have;
25·x + 12·y = 75,000
25·x + 12·x = 75,000
x = 75,000/37 ≈ 2,071 hours = y
The number of hours each will work is approximately 2,071 hours
When the husband and wife contribute the same amount, we have;
25·x = 12·y = 75,000/2
x = 75,000/(2 × 25) = 1,500
∴ x = 1,500 hours
The number of hours the wife works = 1,500 hours
y = 75,000/(2 × 12) = 3,125
∴ y = 3,125 hours
The number of hors the husband works = 3,125 hours
In the figure shown, what is the measure of the indicated angle? °
Answer:
105 degrees
Step-by-step explanation:
Since there mus tbe 180 degrees in a triangle 180-80=100 and then -25 is equal to 75. since the line is 180 degrees, 180-75 = 105
an mark obthe meatin by 9 students of class 6 in exam is 50 among them the mark obtain by 8 student are 60, 40, 50, 30, 80, 40, 45, and 40 what is the mark of remaining 1 student
Answer: 65
Step-by-step explanation:
Since the mean mark of the 9 students is 50. Their total marks will be:
= 9 × 50
= 450
Since the marks obtained by 8 students are given, we add the marks together and this will be:
= 60+40+50+30+80+40+45+40
= 385
The score of the 9th student will be:
= 450 - 385
= 65

Step-by-step explanation:
In parts (a) through (e) below, mark the statement True or False. Justify each answer.
(a) In some cases, a matrix may be row reduced to more than one matrix in reduced echelon form, using different sequences of row operations.
Is this statement true or false?
A. The statement is false. Each matrix is row equivalent to one and only one reduced echelon matrix.
B. The statement is false. For each matrix, there is only one sequence of row operations that row reduces it.
C. The statement is true. It is possible for there to be several different sequences of row operations that row reduces a matrix.
D. The statement is true. The echelon form of a matrix is alwaysunique, but the reduced echelon form of a matrix might not be unique.
Answer:
The correct option is option A
A. The statement is false. Each matrix is row equivalent to one and only one reduced echelon matrix
Step-by-step explanation:
The matrix in echelon form is not in a unique form, as such row reduction can yield an infinite amount of answers. However a row reduced echelon form is unique and will give the same answer in every order that the row operation is performed
The statement is false. Each matrix has only one unique row echelon form, therefore, the correct option is option A.
Circle with the center at (2,4) which goes through the point (-1,0). What is the equation of that circle?
Answer:
(x-2)²+(y-4)² = 25
Step-by-step explanation:
Standard equation of a circle is expressed as
(x-a)²+(y-b)² = r²
Center = (a, b)
Radius = r
Get the radius
r² =(0-4)²+(-1-2)²
r² = (-4)²+(-3)²
r² = 16 + 9
r² = 25
Centre = (2, 4)
Substitute into the equation
(x-2)²+(y-4)² = 25
This gives the required equation

How do you write a linear equation that relates the height of a bunny hop to the weight of the bike. X is weight, y is height in inches. (19,10.2) (21,9.8) (23,9.4)
Answer:
y= -0.2x+14
Step-by-step explanation:
you have to do y2-y1/x2-x1 of any two coordinates or points so you could do 9.8-10.2/21-19 then you get -0.4/2 and that equals -0.2 so -0.2 is now ur slope or M. Next you pick any coordinate like (19,10.2) and you plug that into ur y=mx+b to find the b since you have found the m already from y2-y1/x2-x1. You could do 10.2= 19(-0.2)+b once you do the algebra to solve this you get 14 as your b or y intercept

La probabilité d'un évènement A ne se réalise pas est 3/7 donc:
- P(A) = 3/7 - P(A) = 4/7
- P(A) = 4/10
- P(A) = 7/4
Answer:
P(A) = 4/7.
Step-by-step explanation:
Probability it does not occur = 3/7 so probability it does is 1 - 3/7.
P(A) = 1 - 3/7 = 4/7.

Answer:
Dog - K.C.
Horse - Bo
Bird - Cricket
Cat - Tuffy
The solution is
The name of the dog = K.C.
The name of the horse = Bo
The name of the bird = Cricket
The name of the cat = Tuffy
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A can be calculated as
The species of pets in set A = { Dog , Horse , Bird , Cat }
The names of the pets in set B = { K.C. , Bo , Cricket , Tuffy }
The expressions are
Now , Tuffy and K. C. cannot fly or be ridden
So , Tuffy and K.C. are either the cat or the dog
And , Tuffy runs from the dog
So , Tuffy is the cat and K.C. is the dog from the expression
The bird talks to Bo , so Bo is not the bird
So , from the expression , we get
Therefore , the name of the horse is Bo and name of the bird is Cricket
Hence ,
The name of the dog = K.C.
The name of the horse = Bo
The name of the bird = Cricket
The name of the cat = Tuffy
