2. Solve this problem: There will be 460 people at the sport's award banquet. If each table seats 8 people, how many tables are needed?
A. 3,680 tables
B. 57 tables
C. 58 tables
D. 452 tables
Answer:
C. 58 tables
Step-by-step explanation:
If there are 460 people, and each table seats 8 people, then we divide 460 by 8, giving us 57.5 tables. We cannot have a half of a table, so the answer is 58 tables.

Solve for X 4x−1 =3 Answer:
Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and x = 1.
Answer:
x= 1
Step-by-step explanation:
4x-1=3
+1 +1
4x=4 (divide both sides by 4 to get x alone)

Your boss asks you to interpret the following from a custom paint report he has just received. µ ≥400 ml
The true mean volume of paint in each can is
Blank
or
Blank
400 ml.
Answer:
The true mean volume of p
aint in each can is greater than or equals to 400ml
Step-by-step explanation:
The symbol of μ represents the mean of a data.
Mean can be defined as the average value of a set of data
Let consider the question.
We know that
μ ≥ 400ml
Where the sign ≥ means "greater than or equals to"
Which means that μ is greater than or equals to 400ml
So the solution is:
1st blank = greater than
2nd blank = equals to

The value of x must be equal to 1000
What is the logarithmic function?In mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as
For x > 0 , a > 0, and a ≠1,
y= logₐ x if and only if x = a^y
Then the function is given by
f(x) = logₐx
Given here log x= 3 ⇒x=10³
⇒x=1000
Hence, The value of x must be equal to 1000

If f(x) = x2 − 81 and g(x) = x+9/x-9, find g(x) · f(x).
Answer:
f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares
g(x) = x+9/x-9
g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)
= ( x + 9)(x +9)
= ( x + 9)²
= x² + 18x + 81

Which ordered pair is the solution to the system of linear equations y = negative 7 x + 2 and y = 9 x minus 14?
Answer:
(1, -5) is the solution of the system
Step-by-step explanation:
y = negative 7 x + 2 should be written as y = -7x + 2, and
y = 9 x minus 14 as y = 9x - 14
Use elimination by substitution to solve this system. Equate the two equations together to eliminate y: y = 9x - 14 = -7x + 2.
Combining like terms, we get 9x - 14 = -7x + 2 => 16x = 16
Dividing both sides by 16 yields x = 1.
Substituting 1 for x in the first equation yields the corresponding y-value:
y = -7(1) + 2 = -5
Thus, the ordered pair (1, -5) is the solution of the system.

Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
51/12
as a mixed number
4 1/4
Step-by-step explanation:
first you add 8 to 4 which is 12
so the improper fraction would be 51/12
how to turn it in to a mixed number in simplest form
step 1 - Find Whole Number
Calculate out how many times the denominator goes into the numerator. To do that, divide 51 by 12 and keep only what is to the left of the decimal point:
51 / 12 = 4.2500 = 4
Step 2 - Find New Numerator
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
51 - (12 x 4) = 3
Step 3 - Put Together
Keep the original denominator and use the answers from Step 1 and Step 2 to get this:
4
3
12
Step 4 - Minimize
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 3, which is the greatest common factor, to get the final answer. 51/12 as a Mixed Number is:

A backyard pool has a concrete walkway around it that is 5 feet wide on all sides. The total are of the pool and the walkway is 950 feet. If the length of the pool is 6 feet longer than the width, find the dimensions of the pool.
Answer:
Step-by-step explanation:
Pool:
Width = x ft
Length = (x+6) ft
Pool along with walkway:
Width = x + 5 + 5 = (x + 10) ft
Length = x + 6 + 5 + 5 = (x + 16) ft
Total area of the pool with walkway = 950 sq.ft
length * width = 950
(x+16) * (x + 10) = 950
Use FOIL method,
x*x + x *10 + 16*x + 16 *10 = 950
x² + 10x + 16x + 160 -950 = 0 {Add like terms}
x² + 26x - 790 = 0
Answer:
29.4 length and 21.4 width.
Step-by-step explanation:
To fin the dimensions of the pool we need to use the total area of the pool plus the concrete walkway. Lets say that W is the width and L the length. We know that, the walkway has 3 ft wide, this means that the width and length are increased by 6ft (3ft on each side). So, the total
