A. 33 units
B. 36 units
C. 39 units
D. 42 units
find the volume of the figure
Answer:
1920
Step-by-step explanation:
Volume of larger rectangular prism: 10 * 8 * 14 = 1120
Volume of smaller rectangular prism: 10 * 10 * 8 = 800
Volume of whole prism: 1120 + 800 = 1920
Hence, your answer is 1920

How many different 12-letter arrangements can be made using the letters in the word CARELESSNESS?
From 12 different letters, 3326400 arrangements can be made using the letters in the word CARELESSNESS.
What is permutation?When the order of the arrangements counts, a permutation is a mathematical approach that establishes the total number of alternative arrangements in a collection. Choosing only a few items from a collection of options in a specific sequence is a common task in arithmetic problems.
Among the 12 letters in CARELESSNESS,
there are 4 S’s, 3 E’s, and 1 each of C, A, R, L, N.
There are 12! = 479,001,600 arrangements (permutations) of the 12 letters,
most of which are identical because of repeated letters.
In order that each permutation be distinct, repeat letters have to be accounted for.
4 S’s be in 4! = 24 ways,
3 E’s, in 3! = 6 ways.
And 1! = 1 way.
Distinct permutations as requested,
thus = 12!/(3!)(4!)(1!)
= 3326400.
Therefore, 3326400 different 12-letter arrangements can be made using the letters in the word CARELESSNESS.

What are the values of c and d in the matrix subtraction below? [ 6 8 -11 15 ]-[c+2 3 -5 d-4 ]=[ 22 5 -6 17] C=-14 d= -6 c=-18 d= -6 c=-14 d=2 c=-18 d=2
Answer:
c=-18 d=2
Step-by-step explanation:
[ 6 8 -11 15 ]-[c+2 3 -5 d-4 ]=[ 22 5 -6 17]
The equation tells that when the two matrices are subtracted we get the resultant matrix.
Each element of the first matrix corresponds to each element of the second matrix
From above
6- (c+2)= 22
6- c-2= 22
4-c= 22
-c= 22-4
-c= 18
c= -18
And
15-( d-4)= 17
15- d+4= 17
19-d= 17
-d= 17-19
-d= -2
d= 2
Answer:
D
Step-by-step explanation:
c= -18
d= 2

= 72cm³
Therefore, the volume is 72cm³
Bryce puts $100.00 into an account to use for schopl expenses. The account earns 3%
interest, compounded annually. How much will be in the account after 7 years?
Help!!!
Answer:
A = $122.99
Step-by-step explanation:
A = P + I where
P (principal) = $100.00
I (interest) = $22.99
First, convert R as a percent to r as a decimal
r = R/100
r = 3/100
r = 0.03 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 100.00(1 + 0.03/1)(1)(7)
A = 100.00(1 + 0.03)(7)
A = $122.99
Therefore:
The total amount accrued on a principal of $100.00 at a rate of 3% per year compounded 1 time per year over 7 years is $122.99.

Step-by-step explanation:
Please help me find the value of x!
Exact Answer: x = 16/3
Approximate Answer: x = 5.333
=======================================================
Work Shown:
base = 3x-1
height = x
area of triangle = (base*height)/2
40 = x*(3x-1)/2
40*2 = 3x^2 - x
80 = 3x^2 - x
0 = 3x^2 - x - 80
3x^2 - x - 80 = 0
Now apply the quadratic formula
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-1)\pm\sqrt{(-1)^2-4(3)(-80)}}{2(3)}\\\\x = \frac{1\pm\sqrt{961}}{6}\\\\x = \frac{1\pm31}{6}\\\\x = \frac{1+31}{6} \ \text{ or } \ x = \frac{1-31}{6}\\\\x = \frac{32}{6} \ \text{ or } \ x = \frac{-30}{6}\\\\x = \frac{16}{3} \ \text{ or } \ x = -5\\\\x \approx 5.333 \ \text{ or } \ x = -5\\\\[/tex]
A negative height doesn't make sense, so we ignore x = -5
The only solution is x = 16/3 which approximates to x = 5.333

Each of the letters of the word ALABAMA are written on a piece of paper and then
put into a bag. A piece of paper is drawn at random. What is the theoretical
probability of NOT drawing an A?
Answer:
3/7
Step-by-step explanation:
There are 7 letters in ALABAMA. And there are 4 A's in ALABAMA. So if you're trying to not get an A then you would subtract 4 from 7. Which you would get 3/7 of the letters in ALABAMA are not A.

Answer: 1/4 chance (second option on the screen)
Step-by-step explanation:
dw probability is confusing to a lot of ppl
so if you count the sections theres 8 in all
to see the probability we must find how many times we will get a positive outcome, or what we want (the multiple of 3)
lets see how many multiples of 3 there are
theres 3 and 6
thats two out of the eight possible outcomes at any moment u spin the spinner
so thats an 2/8 chance
you can simplify that fraction to a 1/4 chance, so its the second option on your screen

Answer:
B) 63 ft.
Step-by-step explanation:
To find how long it takes for a rotation, we need to find the circumference.
To do so, we use the formula 2(pi)r
To find the radius, we divide the diameter in half :
d = 20
r = d/2
r = 20 / 2
r = 10
Then, we plug that into the formula :
2(pi)10
Insert that into your calculator :
2(pi)10 = 62.83
Simplify :
62.83 = 63 ft.
