Which of the following values is NOT equal to 11(7-1)?
3 x 22
5 + 1(22-10)
6 x 7 + 8 x 3
1084 - 1018
(6+5)6
Answers
Answer:
5 + 1(22-10)
Step-by-step explanation:
3 × 22 = 66
5 + 1(22-10) =5(12) = 60
6 × 7 + 8 × 3 = 42 + 24 = 66
1084 - 1018 = 66
(6 + 5)6 = (11)6 = 66
Answer:
5 + 1(22-10)
Step-by-step explanation:
First we need to solve for 11(7-1). Since the 7 - 1 is in the parenthesis it is what you do first. We know 7 - 1 equals 6. Since we got 6 as our answer for 7 - 1 we would take the 6 and multiply it with the 11 in the equation 11(7-1). If we would multiply 6 x 11 we would have an answer of 66.
Now we need solve each equation to see which one doesn't equal 66.
3 x 22 = 66 therefore it wouldn't be our answer.
5 + 1(22-10), we should always remember that we solve the equation with the parenthesis first. So if we would solve 22 - 10 we would get 12. Next we need to solve 5 + 1 and we should know this equals to 6. Now since we have our answer to both equation we would need to add 12 + 5 If we added those two number we'd get 17. There this would be our ANSWER.
6 x 7 + 8 x 3, we'll need to multiply 6 x 7 and then 8 x 3 after we get our answers to those equations we would need to add them and see if we would get 66 or not. So first I would multiply 6 x 7 and when I multiplied it I got 42. Next we would multiply 8 x 3 and that would equal 24. Now we need to ad 42 + 24. When we add 42 + 24 we get the answer of 66. Therefore this wouldn't be our answer.
1084 - 1018, this one would be easy to solve so we would nee to solve 1,084 - 1,018. If you don't know how to solve that it's okay! We can do it together. So if you write it in a paper or on something you could write it like I'll use a board. You would need to have 1,084 written in the top because that's the biggest number and 1,018 in the bottom because that a smaller number then 1,084. So we would nee to solve the one's place first. We wouldn't be able to solve 4 - 8 so we need to go over to the tens place and take from there now since we took from the 8 it'd become 7 and now the 4 is 14. So we'd do 14 - 8 for the ones place and we have our answer as 6. Now we need to solve the tens place 7 - 1 we know that equals 6 so we need to put 6 under our tens place. Next we go to the hundred place and do 0 - 0 and that's really easy haha it'd equal 0. So under the hundred place we can put 0 or leave it blank I left mines blank. Now finally we would do 1 - 1 and we know that equals 0 as well. So we can put 0 under our thousand place or leave it blank, I left it blank. Therefore this equals 66 so this wouldn't be our answer. Below in the picture I showed my work. :)
(6+5)6, first we do what's in the parenthesis. Which is 6 + 5 that'd equal 11. So since now we have 11 as our answer for 6 + 5 we'd need to do 11 x 6 and that would equal 66. Therefore our answer for this equation would be 66 so it wouldn't be our answer..

Step-by-step explanation:
Add all the numbers in the graph together, you get 194.
Now, subtract 194 from 660, you get 466. That's how much profit the company makes.
The required generated profit on iPhone 4s is given as $466.2.
What is the cost price and selling price?The cost price is defined as the is the price of producing something while the selling price is the amount that the buyer pays.
Here,
As of the mentioned data,
Cost of making an iPhone = $193.8
The selling price of the iPhone = $660
Profit is meant how much money is generated from the product besides the product cost price.
Profit = selling price - cost price
Profit= 660 - 193.9
Profit = $466.2
Thus, the required generated profit on iPhone 4s is given as $466.2.

On which interval(s) is the function f(x) = x^3+3x^2−4x−12 increasing?
Answers
The interval at which the function x³ + 3x² - 4x - 12 increases is
x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).
We have,
x³ + 3x² - 4x - 12
We need to draw a graph to see at which interval the graph is increasing.
The graph is given below.
We see that the graph is increasing from x = -∞ to x = -2.5 and from x = -2.5 it decreases till x = 0.5 and again from x = 0.5 it increases to x = ∞.
So we can write the interval as:
x ∈ (- ∞, - 2.5) and x ∈ (0.5, ∞)
We can write it as one single interval as:
S = (- ∞, - 2.5) ∪ (0.5, ∞)
Thus the interval at which the function x³ + 3x² - 4x - 12 increases is
x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).

for the two given fractions 3/4 and 1/6 we have:
sum = 11/12product = 1/8quotient = 9/2How to work with fractions?Here we have two fractions, 3/4 and 1/6, and we want to find the sum, product, and quotient between them.
First let's do the sum:
3/4 + 1/6
We just need to find a common denominator, which can be 12, so we can rewrite it as:
9/12 + 2/12 = 11/12
The sum of the two fractions is 11/12
Now the product, it is, we multiply denominator with denominator and numerator with numerator, we will get:
(3/4)*(1/6) = (3*1)/(4*6) = 3/24 = 1/8
The product between the two fractions is equal to 1/8.
Finally, the quotient, this is:
The product between the first numerator and second denominator, and between the first denominator and second numerator, so the quotient becomes:
(3/4)/(1/6) = (3/4)*(6/1) = (3*6)/(4*1) = 18/4 = 9/2

How can you use the
Product of Powers, Power of a Product, and
Power of a Power Laws to evaluate and write
equivalent numerical expressions with whole-
number exponents?
Answers
Answer:
An equivalent numerical expression with whole-
number exponent using these laws can be written as:
1) 2² × 2³ = 2^5 => using product of Powers
2) 2² × 3² = (2×3)² = 6² => using power of a Product
3) (2²)³ = 2^6 => using power of a power
Step-by-step explanation:
First of all, let us understand some terms like;
1) Exponentiation: It is the mathematical process of raising one integer to the power of another. The base is the first integer, while the exponent is the second.
2) Power: A power is a phrase that depicts the same component being multiplied repeatedly.
3) Exponent: The number of times the base is used as a factor is represented by the exponent.
Now, let us understand the 7 Laws of Exponents;
1) a^m × a^n = a^(m+n) => Product With the Same Bases
2) a^m / a^n = a^(m-n) => Quotient with Same Bases
3) (a^m)^n = a^(m×n) => Power Raised to a Power
4) a^n × b^n = (ab)^n => Product to a Power
5) a^n / b^n = (a/b)^n => Quotient to a Power
6) a^0 = 1 => Zero Power
7) a^(-m) = 1/a^m => Negative Exponent Rule
Furthermore, an equivalent numerical expression with whole-
number exponent using these laws can be written as:
1) 2² × 2³ = 2^5 => using product of Powers
2) 2² × 3² = (2×3)² = 6² => using power of a Product
3) (2²)³ = 2^6 => using power of a power

The two values of y after factorizing the given quadratic equation are 0, -0.5
The given equation is quadratic as the order of the equation is 2. In a quadratic equation with a single variable, the variable will have two different values which satisfy the equation. These values of the variable can be real and different, real and equal, or imaginary.
So, there will be two values of y.
Consider the given equation,
10y^2 + 12y = 7y
10y^2 +12y - 7y = 0
10y^2 + 5y = 0
Since the coefficients of y and y^2 are both multiples of 5,
5*(2y^2 + y) = 0
2y^2 + y = 0
Taking y as a common factor,
y*(2y+1) = 0
Now, we get two cases,
y = 0 or 2y + 1 = 0 => y = -(1/2) = -0.5
Therefore, y = 0 or y = -0.5

What does the total rental cost of each company entails?
The total rental cost of each company consists the fixed service charges and the daily charge which can be multiplied by the total of number of days of rental to determine total charges overall.
Hertz:
total charges=32+42x
when x=6 days
total charges=32+(42*6)
total charges=$284
Enterprise:
total charges=24+46x
when x=6 days
total charges=24+(46*6)
total charges=$300
Renting for 4 days:
total charges(Hertz)=32+(42*4)
total charges(Hertz)=$200
total charges(Enterprise)=24+(46*4)

The baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.
What is are the approximate and exact cost of each pizza bought by a baseball coach?
In this problem we know that a baseball coach spends a total of $ 118.25 on buying 11 pizzas. First, we need to estimate the amount of money spent per each pizza bought, which is found by means of multiplication tables and the supposition of truncation, that is, finding the maximum integer less than or equal to the real total cost.
By direct inspection we find that 10 times the 11 pizzas is equal to $ 110, which is the maximum integer less than or equal to the real total cost. Then, we estimate a cost of $ 10 per each pizza bought. Second, the exact unit cost is found by dividing the total by the number of pizzas:
c = $ 118.25 / 11
c = $ 10.75
In a nutshell, the baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.

Find the average rate of change of
g(x)=-2x^3+5 from z=-4 to x=3
Answers
The average rate of change of the function from x == -4 to x = 3 is calculated as: -26.
How to Determine the Average Rate of Change of a Function?The formula for determining the average rate of change across a given interval of a function is expressed as:
Average rate of change = g(b) - g(a)/b - a.
Given the function, g(x) = -2x³ + 5 to find the average rate of change from x = -4 to x = 3, do the following:
a = -4
g(a) = g(-4) = -2(-4)³ + 5 = -2(-64) + 5 = 128 + 5 = 133
b = 3
g(b) = g(3) = -2(3)³ + 5 = -2(27) + 5 = -54 + 5 = -49
Substitute the values into g(b) - g(a)/b - a:
Average rate of change = (-49 - 133)/(3 - (-4))
Average rate of change = -182/7
Average rate of change = -26
Thus, the average rate of change of the function from x == -4 to x = 3 is calculated as: -26.
