How can you use a unit cube to find the volume of a prism? Explain.
(points)
Answer:
with times hight
Step-by-step explanation:
multiply with and hight together to get a full lay out of the prisms and if the are halves i usauly add them together to form one unite hope this help and that were on the same page
Answer:
To use a unit cube, you have to multiply the length and the width just like finding the area of a 2D shape. You will then take your "area" and multiply that by the height of the object.
Step-by-step explanation:
Example, if I have a rectangular prism that is 10 inches long, 4 inches wide, and 6 inches tall, I can multiply 10 and 4 to get 40. I will then take the 6 inches, and multiply it to 40. 40x6=240. The volume of my prism is 240.
I would also like to point out that you can multiply the factors in any order because of the commutative property
4. If the length and width of the figures below are doubled, how will it affect the volume of the figure?
7 in.
6 in.
9 in
The volume will be doubled.
0
The volume will be quadrupled.
The volume will be 8 times greater
The volume will be 14 times greater
CLEAR ALL
Answer:
8 times greater.
Step-by-step explanation:
Lengths are times 2 so:
Volume = 2^3 times greater
Answer:
8

factorise 4a-6ab-18ac
Answer:
Step-by-step explanation:
4a-6ab-18ac
=2a(2-3b-9c)
The required factorisation of the given equation is 4a-6ab-18ac = 2a(2 - 3b - 9c).
What is factorisation?In mathematics, factorisation or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.
The given equation is,
4a-6ab-18ac
So factorising each term we have,
4a = 2*2*a
6ab = 2*3*a*b
18ac = 2*3*3*a*c
Thus the equation becomes,
4a-6ab-18ac = 2*2*a - 2*3*a*b - 2*3*3*a*c
taking 2*a common we get,
4a-6ab-18ac = 2a(2 - 3b - 3*3*c)
or, 4a-6ab-18ac = 2a(2 - 3b - 9c)
which is the the required factorisation of the equation.
Thus, the required factorisation of the given equation is 4a-6ab-18ac = 2a(2 - 3b - 9c).

Answer :
1. Choose A, 2. Choose B, 3. Choose C, 4. Choose A, 5. Choose A
Explanation :
1. 91, 85, __, 73, __, 61
We see that each number has a difference of 6. Therefore, 91 minus 6 is 85. 85 minus 6 is 79, 79 minus 6 is 73, 73 minus 6 is 67, 67 minus 6 is 61.
Therefore, the missing numbers are :
91, 85, 79, 73, 67, 61
So, choose A.
2. 38, 46, __, 62, __, 78
We see that each number has a difference of 8. So, 38 plus 8 is 46, 46 plus 8 is 54, 54 plus 8 is 62, 62 plus 8 is 70, 70 plus 8 is 78.
Therefore, the missing numbers are :
38, 46, 54, 62, 70, 78
So, choose B
3. 34, 39, __, __, 54, 59
We see that each number has a difference of 5. So, 34 plus 5 is 39, 39 plus 5 is 44, 44 plus 5 is 49, 49 plus 5 is 54, 54 plus 5 is 59.
Therefore, the missing numbers are :
34, 39, 44, 49, 54, 59
So, choose C
4. 15, 30, __, 60, __.
We see that each number has a difference of 15. So, 15 plus 15 is 30, 30 plus 15 is 45, 45 plus 15 is 60, 60 plus 15 is 75.
Therefore, the missing numbers are :
15, 30, 45, 60, 75.
So, choose A.
5. 829 x __ = 829
∴ 829 x 1 = 829
So, choose A.
Use the definition of the derviative to compute the derivative of f(x)= 1- 7x^2 at the specific point x=2.
Answer:
[tex]f'(x) = -28 \ at \ x = 2[/tex]
Step-by-step explanation:
[tex]f'(2) = \lim_{h \to 0}\frac{f(2+h)) -f(2)}{h} \\\\f(2+h) = 1 - 7(2+h)^2 = 1 - 7(4 +h^2 +4h) = 1 - 28 - 7h^2 - 28h = - 7h^2 -28h - 27\\\\f(2) = 1 - 7(2^2) = 1 - 28 = -27\\\\f(2+h) - f(2) = -7h^2 - 28h - 27 - (-27) = -7h^2 -28h -27 + 27 = -7h^2 -28h\\\\f'(2) = \lim_{h \to 0}\frac{-7h^2 - 28h}{h} \\\\[/tex]
[tex]= \lim_{h \to 0} \frac{h(-7h -28)}{h}\\\\= \lim_{h \to 0} (-7h -28)}\\\\= -7 (0) - 28\\\\= -28[/tex]

Step-by-step explanation:
The students are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question, we have that:
13 + 7 = 20 teachers, which means that N = 20.
7 history teachers means that k = 7.
Two teachers for each student, which means that n = 2.
What is the approximate probability that a random student on the trip will be assigned to a group led by two history teachers?
This is P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,20,2,7) = \frac{C_{7,2}*C_{13,0}}{C_{20,0}} = 0.1105[/tex]
So close to 11.1%, and the correct answer is given by option A.

Rachel uses 75 inches of ribbon to make 4 bows. She uses the same amount of ribbon to make each bow. 1 foot = 12 inches 1 yard = 3 feet How many yards of ribbon will Rachel use to make 12 bows? Enter the answer in the box. yards
Answer: 6.25 yards
Step-by-step explanation:
75 inches = 4 bows
To get 12, you have to multiply 4 by 3. Therefore, you also have to multiply 75 by 3.
75*3 is 225.
225 inches = 12 bows
225 inches is 6.25 yards. Hope this helps :)

The operation is defined on the set R of real numbers by ab=ab+a.
Determine whether or not the operation is associative.
Please I need help.
Answer:
ab=ab+a
We need to check the following:
(ab)c=a(bc) or not
LHS
(ab)c=(ab+a)c
=(ab+a)c+(ab+a)
=abc+ac+ab+a
RHS
a(bc)=a(bc+b)
=a(bc+b)+a
=abc+ab+a
as LHS ≠ RHS, the operation is not associative

You are looking to save money to start a business. You currently have $500 saved up. We JustWantUrMoney Bank offers a savings account with 12%
interest, compounded annually. How much money would you have after 10 years? Round to the nearest cent, if necessary.
Answer:
You would have $1552.9 after 10 years.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
You currently have $500 saved up.
This means that [tex]P = 500[/tex]
12% interest, compounded annually.
This means that [tex]r = 0.12, n = 1[/tex].
How much money would you have after 10 years?
This is A(10). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(10) = 500(1 + \frac{0.12}{1})^{10}[/tex]
[tex]A(10) = 1552.9[/tex]
You would have $1552.9 after 10 years.
