Answer:
14
Step-by-step explanation:
Given the indicinal expression 64^5/6 + 27^2/3 - 81^3/4
According to indices;
[tex]a^{m/n} = (\sqrt[n]{a}) ^m[/tex]
Applying this to the question
[tex]64^{5/6} \\= (\sqrt[6]{64}) ^5\\= 2^5= 32[/tex]
Similarly
[tex]27^{2/3}\\= (\sqrt[3]{27}) ^2\\= 3^2\\= 9\\[/tex]
Also;
[tex]81^{3/4}\\= (\sqrt[4]{81}) ^3\\= 3^3\\= 27[/tex]
Substitute inti the original equation
64^5/6 + 27^2/3 - 81^3/4
= 32 + 9- 27
= 41 - 27
= 14
Hence the required answer is 14

johns dinner costs $52.30. Sales tax is 6.5% and he wants to leave a 20% tip for the waitress. what is the total cost for johns meal ???????
Answer:
The total cost for john's meal would be $66.84
Step-by-step explanation:
6.5% of 52.30 = 3.3995
52.30 plus 3.3995 = 55.6995
20% of 55.6995 = 11.14$
55.6995 + 11.14 = $66.84
Which value of x satisfies the inequality below?
13< x
Answer:
20
Step-by-step explanation:
since the sign is pointing to the "greater number"
any number over 13 is fine
The value of x can be 14, 15, .... and so on.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12. This is a real-world example of an inequality.
Given:
13< x
So, we have to choose the value which are greater than 13.
The value of x cannot be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.
Thus, the value of x can be satisfies by 14, 15, .... and so on.

Evaluate 6 + x when x = 3.
Answer:
6 + x = 9
Step-by-step explanation:
We know that x = 3, and that we need to add x (which equals 3) to 6.
So, all we need to do is add 6 + 3.
6 + x = 9
We know this because for the expression 6 + x, we replace x with it's given value, which is 3.
⬇
6 + 3 = 9

Which function or functions have a slope equal to the slope of Function 1?
Answer:
function 2 only
Step-by-step explanation:
The Function that have a slope have 1 is Function 1.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
From function 1, the slope is
Slope = (0-2)/ (1- 3)
Slope = (-2)/ (-2)
Slope = 1
Now, for function 2 the slope is
Slope = 2
and, for Function 3 the slope is
Slope = 0
and, For function 4 the slope is
Slope = 3/2
Thus, Slope of function 1 have slope 1.

spell the word ENVELOPE?
A.
3/28
B.

c.
1/1120
D.
1/6720
The probability the letters will spell the word ENVELOPE is 1/6720 option (D) 1/6720 is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
If all the letters in the word ENVELOPE are randomly rearranged,
As we know, a permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
From the definition of the permutation and combination we can calculate the total number of arrangements:
E :: 3
N :: 1
V :: 1
L :: 1
O :: 1
P :: 1
The arrangement Letters:
E,L,N,O,P,V
Total Number of Letters:
8
Total Number of Unique Letters:
6
Total arrangements = 8!/3!
Total arrangements = 8×7×6×5×4
Arrangements = 6720
Total number of outcomes = 6720
Number of favorable outcomes = 1
Probability = 1/6720
Thus, the probability the letters will spell the word ENVELOPE is 1/6720 option (D) 1/6720 is correct.

A business owner receives a $5,000 loan with 13%
interest,charged at
the end of each year.
Write an expression to represent the amount owed, in dollars, after the
given number of years of making no payments.
1. after 1 year
2. after 2 years
3. after tyears
Answer:
Step-by-step explanation:
Given;
Loan = $5,000
Interest rate = 13% charged at the end of each year
Question 1. Expression to represent the amount owed, in dollars, after;
a. After 1 year.
Owed amount = Loan + accrued interest= $5000 + ( 13% * $5000 * 1 year )
= 5650
b. After 2 years.
Owed amount = Loan + accrued interest
= $5000 + ( 13% * $5000 * 2 years )
= $6300
c. After t years
Owed amount = Loan + accrued interest= $5000 + ( 13% * $5000 * t years )= $5000 + $650t
Question 2. Explain how to convince someone that your expression for t years is correct.
Amount owned= borrowed amount + accrued interest
Accrued interest = Interest rate per year * Loan amount * time in years ( for simple interest case )
Loan amount = $5000
Time = t years
Interest rate = 13% per year
Accrued interest = 13% * $5000 *t years= $650t
Amount owned will therefore be; = Loan amount + Accrued interest
= $5000 + $650t

How long is the wire that supports the tree?
5.6 ft
3.3 ft
Answer:
6.5 ft
Step-by-step explanation:
You must use Pythagoras theorem, which is a² + b² = c², then square root c to get answer
if 5.6 = a and 3.3 = b
5.6²+3.3²=42.25(=c²)
42.25 = c²
square root both sides
6.5 = c
Answer:
6.5 ft.
Step-by-step explanation:
To find this you can use the Pythagorean Theorem. [tex]a^2+b^2=c^2[/tex]
[tex]5.6^2 + 3.3^2=C^2[/tex]
31.36+10.89=[tex]C^2[/tex]
42.25=[tex]C^2[/tex]
NOW you have to square root both sides of the equation
[tex]\sqrt{42.25} = \sqrt{C^2}[/tex]
You square root both sides so you can get ride of the exponent on C
So, your answer is 6.5=C
hope this helps :)
p.s. for further questions, [tex]c^2[/tex], is always the opposite side of the right angle. :)
solve the linear equations elimination -2x+3y= 7 5x+8y= -2
Answer:
x=-2, y= 1
Step-by-step explanation:
Given data
-2x+3y= 7 --------------1
5x+8y= -2--------------2
Multiply 1 by 5 and 2 by 2 and add
-2x+3y= 7 X 5
5x+8y= -2 X 2
-10x+15y= 35
10x+16y= -4
0x+31y= 31
31y= 31
y= 31/31
y= 1
put y= 1 in eqn 1
-2x+3y= 7
-2x+3(1)= 7
-2x+3=7
-2x= 7-3
-2x= 4
x=- 4/2
