Final answer:
The inequality 5m - 7 > 16 is true for all numbers greater than 4 in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. After isolating m in the inequality, we find that m must be greater than 4.6. Since we're dealing with whole numbers, the inequality holds for numbers greater than 4.
Explanation:
To solve the inequality 5m − 7 > 16, we first isolate the variable m:
Add 7 to both sides of the inequality to get: 5m > 23.
Next, divide both sides by 5 to find the value of m: m > [tex]\frac{23}{5}[/tex], which simplifies to m > 4.6.
Since m must be greater than 4.6, and we are given a set of whole numbers, we are looking for all numbers greater than 4 in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. This means the inequality holds true for all numbers greater than 4 in the set.

X to the power of 2 equal 100 how to solve
Answer: {-10, +10}
Step-by-step explanation: A common mistake in this problem would be to say that if x² = 100, x must equal 10.
Remember however that before you do anything else you must set the equation equal to 0.
So our first step is to subtract 100 from both sides to get x² - 100 = 0. Next, factor the left side to get (x + 10)(x - 10) = 0.
So either x + 10 = 0 or x - 10 = 0.
Solving for x in each equation, we have x = -10 or x = +10.
So our answer is not just 10, it's -10 or +10.

Answer: C. (2, 4)The 4 people in your crew each spent 4 hours laying sod. How many person-hours is this?
Since there are 4 people and they each spent 4 hours working, all we have to do is multiply the number of people (4) by the amount of hours each person spent (4)
4 x 4 = 16
Therefore, the total amount of hours is 16
Hope this helps you
-AaronWiseIsBae
Answer:
16 hours
Step-by-step explanation:
Given: There are 4 people in your crew.
Each spent 4 hours of laying sod.
To find the person hours, we have to multiply the number of people (4) by the amount of hours each person spent (4).
Total number of hours = Number of persons * Number of hours spent
Total number of hours = 4 x 4 = 16 hours
Therefore, the total amount of hours is 16.

What are the discontinuities of the function f(x) = the quantity x squared minus 36 over the quantity 4x plus 24?

the factor (x + 6) cancels leaving the simplified version of f(x)
f(x) = [tex]\frac{x-6}{4}[/tex]
the removal of the factor (x + 6) from the numerator/denominator means there is a discontinuity at x + 6 = 0 , that is x = - 6

3. At a bargain store, Tanya bought 3 items that each cost the same amount. Tony bought 4 items that each cost the same amount, but each was $2.25 less than the items that Tanya bought. Both Tanya and Tony paid the same amount of money. What was the individual cost of each person's items?
(a) Write an equation. Let x represent the cost of one of Tanya's items.
(b) Solve the equation. Show your work.
(c) Check your solution. Show your work.
(d) State the solution in complete sentences.
By setting up an equation with x as the cost of Tanya's items, we find that each of Tanya's items cost $9.00. Tony's items, being $2.25 cheaper, cost $6.75 each. The solution is checked by ensuring both Tanya's and Tony's total expenditure was equal.
The question asks us to find the individual cost of items purchased by Tanya and Tony at a store, given that Tony's items each cost $2.25 less than Tanya's but both spent the same amount overall.
Equation Setup
Let x represent the cost of one of Tanya's items. Since Tanya bought 3 items, she spent 3x dollars. Tony's items each cost $2.25 less, so they cost (x - $2.25) each. Tony bought 4 items, spending 4(x - $2.25). Since both spent the same amount:
3x = 4(x - $2.25)
Solving the Equation
To solve for x:
Distribute the 4 on the right side of the equation to get 3x = 4x - $9.00.Subtract 4x from both sides to get -x = -$9.00.Divide both sides by -1 to get x = $9.00.So, each of Tanya's items cost $9.00.
Checking the Solution
To verify:
Tanya's total is 3($9.00) = $27.00.Tony's total is 4($9.00 - $2.25) = 4($6.75) = $27.00.Both totals match, confirming that the solution is correct.
Tanya's items each cost $9.00, while Tony's items, costing $2.25 less, each cost $6.75.
What is the remainder of 23870 divide by 38
The remainder when dividing 23870 by 38 is 16.
Explanation:To find the remainder when dividing 23870 by 38, you divide the larger number (the dividend) by the smaller number (the divisor). If the division operation does not produce a whole number, the 'left over' digits are considered the remainder. When you divide 23870 by 38, the quotient (or the answer) is 628, and the remainder is 16. Therefore, 16 is the remainder when 23870 is divided by 38.

Use the complex conjugate to find the absolute value of 8+12i
A. 12
B.Square root of 208
C. Square root of 84
D. 8
Answer:
A. 12
Step-by-step explanation:
i= use complicated conjugate to search out definite quantity of 8 + 12i
i = 12i
i= twelve × ei 90°
i = twelve × (cos 90° + i sin 90°)
r = |i| = twelve
The absolute value of the complex number 8 + 12i is found by squaring the real part, squaring the imaginary part, adding these two results, and then taking the square root. This results in the square root of 208.
Explanation:The absolute value of a complex number a + bi is calculated through the formula sqrt(a² + b²). So, to find the absolute value of the complex number 8 + 12i, we substitute a with 8 and b with 12. We can perform the calculations as follows:
Square the real part, a: 8² = 64,Square the imaginary part, b: 12² = 144,Add the results: 64 + 144 = 208,Take the square root of the sum: sqrt(208). Thus, the absolute value is the square root of 208.Learn more about Complex Numbers here:https://brainly.com/question/20566728

a boat is marked up to 20% on the original price . The original price was $50 what is the sales price of the boat before sales tax?
Answer:
60
Step-by-step explanation:
Answer:
60 dollars.
Step-by-step explanation:
Markup is nothing but the difference between the selling price of a good or service and its cost. It is expressed as a percentage above the cost. In short, we can say that it is the added price over the total cost of the good or service that provides the seller with a profit.
Original price = 50 dollars
ADD: 20% on original price = Markup price = 50(20/100) = 10 dollars
Hence Sales price = 50+10 = 60 dollars

Kelly bought a new car for $20,000. The car depreciates at a rate of 10% per year. Write an equation to model the car's value.
y=20,000-.10x
with x being the number of years
Answer:
[tex]y=\$20,000\cdot (0.90)^x[/tex]
Step-by-step explanation:
We have been given that Kelly bought a new car for $20,000. The car depreciates at a rate of 10% per year. We are asked to write an equation to model the car's value.
Since car's value depreciates by 10% per year, so value of car is depreciating exponentially.
We know that an exponential decay function is in form [tex]y=a\cdot (1-r)^x[/tex], where
a = Initial value,
r = Decay rate in decimal form.
Let us convert 10% into decimal form as:
[tex]10\%=\frac{10}{100}=0.10[/tex]
Upon substituting our given values in decay formula, we will get:
[tex]y=\$20,000\cdot (1-0.10)^x[/tex]
[tex]y=\$20,000\cdot (0.90)^x[/tex]
Therefore, our required equation would be [tex]y=\$20,000\cdot (0.90)^x[/tex].

3( x -5)- 5x= 25+ 6x What is the answer and how do you solve this??
To solve this equation, distribute, combine like terms, and isolate the variable, x.
Explanation:To solve this equation, we need to simplify both sides and isolate the variable, x.
Starting with the left side, distribute the 3 to the terms inside the parentheses: 3x - 15 - 5x = 25 + 6x.
Combine like terms on both sides of the equation: -2x - 15 = 25 + 6x.
Add 2x to both sides of the equation and add 15 to both sides: -15 - 25 = 6x + 2x.
Simplify the equation: -40 = 8x.
Finally, divide both sides by 8 to solve for x: x = -5.
