Answer:
50 inches, or 4 1/6 feet
Step-by-step explanation:
If one inch is equal to 6 1/4 feet, we can translate this number from feet to inches.
4 1/6 feet = 75 inches.
Now we can take 75 and find out 2/3 of it.
2/3 of 75 is 50.
The answer is 50 inches.
If you want to convert the answer from feet to inches, its simple.
12 × 4 = 48
50 - 48 = 2
2 inches is equal to 1/6 of a foot.
The answer in feet, is 4 1/6 foot.

During WW! mortars were fired from trenches 3 feet down The mortars had a velocity of 150 ft/s. Determine how long it will take for the mortar shell to strike its target?
In 0.02 seconds, the mortar shell will make contact with the target.
How to determine the time it will take the mortar shell to strike the targetThe formula for velocity, which is equal to distance / time, is used to calculate how long it will take to hit the target.
In the problem, the distance is 3 feet, and the velocity is given to be 150ft/s
therefore
150 = 3 / time

The perimeter of a rectangle is 34 centimeters. The length is two more than twice the width. Find the length and the width of the rectangle.
The length of a rectangle is 12 units and width is 5 units.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
To determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given that the Perimeter of a rectangle = 34 cm.
and, length is two more than twice the width.
Thus the width be x.
So, the length = 2x + 2
So,
Perimeter of rectangle = 2 ( l +w )
34 = 2( x+ 2x+ 2)
17 = 3x +2
3x = 15
x= 5

which property in math is (n+2.9)+0.3=n+(2.9+0.3)
Notice that the order the numbers are written on both sides is the same:
n, then 2.9, then 0.3
Because the order is the same and all that changed were the parentheses (the way the numbers were grouped), this is the associative property of addition.
The associative property is about the groupings. You can remember this by thinking about that fact that associations are groups.

if you have a square with a length of 5x, write an expression for the perimeter of the square.
The perimeter of a square with a length of 5x can be represented by the expression 45x. This is because the perimeter of a square is equal to the length of any side of the square multiplied by the total number of sides, which is 4 for a square. So, for a square with a length of 5x, the perimeter would be 45x, or 20x.
If $8000 is invested at an annual interest rate of 5% and compounded annually, what is the balance after 4 years?
Answer: 7 years
Step-by-step explanation:
We make the assumption that 8000 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $10\%=8000$.
Step 4: In the same vein, 100%=8000$.
So divide that by 5% 0.05%
Then multiply it by 5 0.0025%

What is meant by a function?A function from a set X to a set Y in mathematics assigns to each element of X exactly one element of Y. The domain of the function is the set X, and the codomain of the function is the set Y.
The first known attempt to define function can be found in the writings of Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. The concept of a function was codified in terms of set theory at the end of the nineteenth century, which substantially expanded its realms of applicability. The range of possibilities for variation or the distances between them: pricing for various grades of steel; a variety of designs. a thing's operation or action's reach or extent: accessible to the eye. a projectile's range is how far a weapon can or will shoot it.

What is the estimated salary for an employee with 7 years of experience?
The estimated salary for an employee with 7 years of experience will be;
⇒ Estimated Salary = 41,842.71
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The estimated regression equation was determined to predict salary based on years of experience is,
⇒ Estimated Salary = 22,717.59 + 2732.16(Years of Experience)

Greg works two part time jobs. One job is at a gas station that pays $12 an hour and the other is delivering groceries for $15.50 an hour. Between the two jobs Greg wants to earn at least $390 a week. Let x be the number of hours he works at the gas station and let y be the number of hours he works delivering groceries. Write an inequality that models this situation.
The required inequality model for this situation is 12x + 15.5y ≥ 390.
What are inequalities?
The mathematical expressions with inequalities are those with unequal sides on both sides. Unlike equations, we compare two values when we work with inequality. The equal sign is substituted between by the less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
"A connection is termed an inequality if two real numbers or algebraic expressions are connected by the symbols ">,"< "," <="," or ">=."
For instance, x>3 (x should be greater than 3)
If there is just one variable, the inequality is said to have an open sentence.
Instance: x 6 (x is less than 6)
Double Inequalities: If the statement demonstrates a double relation between the expressions or the numbers, the inequality is said to be a double inequality.
Instance: 3 x 8 ( x is greater than or equal to 3 and less than 8)
Given, the gas station pays $12 an hour and delivers groceries for $15.50 an hour.
And, x be the number of hours he works at the gas station and let y be the number of hours he works delivering groceries.
Then, total earnings in gas station = 12x
total earnings for delivering groceries = 15.5y
So, based on the given inequality condition
12x + 15.5y ≥ 390
Hence, the required inequality model for this situation is 12x + 15.5y ≥ 390.

Cari is searching online for airline tickets. Two weeks ago, the cost to fly from boston to denver was $220. Now the cost is $295. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
The percent increase with the additional baggage fee for airline would be $125 / $220 x 100% = 56.82%.
What is meant by the term percentage?A number can be expressed as a fraction of 100 using a percentage. It may be computed by dividing the number by the total and multiplying by 100. It is commonly represented by the sign "%". The percentage of men, for instance, would be 25/100 x 100, or 25%, if there were 100 persons in all.
In a variety of areas, including statistics, finance, and education, percentages are often employed. For instance, in finance, percentage increase in stock prices are used to gauge a market's or company's success. In education, grades are frequently given as percentages to represent class marks.
How to solve?
The increase in the cost of the ticket is $295 - $220 = $75
The percent increase is $75 / $220 x 100% = 34.09%.
If the airline charges an additional $50 baggage fee, the new ticket price would be $295 + $50 = $345.
The increase in the cost of the ticket with the additional baggage fee would be $345 - $220 = $125.
The percent increase with the additional baggage fee would be $125 / $220 x 100% = 56.82%.

What is the average rate of change of this function on the interval from x = 1 to x = 3? f(x)=10(2)x Enter your answer in the box.
Answer:
30
Step-by-step explanation:
The way to figure out the average rate of change is to divide the change in f(x) and divide that by the change in x. A formula for this is [tex]\frac{f(x_{1})-f(x_{2})}{x_{1}-x_{2}}[/tex]
1.) By this definition, we need to figure out our x1 and x2. We can say the x1 = 3 and x2 = 1
2.) Next, we plug it into the formula. We will get [tex]\frac{f(3)-f(1)}{3-1}[/tex].
3.) If we simplify, we will get 10(2)^3 - 10*2 divided by 2, which is equal to 10*4 - 10 = 30.
10/8 = n/10 proportions please
[tex]\displaystyle n=\frac{25}{2}[/tex]
Step-by-step explanation:A proportion is a set of equal ratios.
Cross Multiplication
The most common (and easiest) way to solve a proportion is cross multiplication. To cross-multiply, multiply the numerators by the opposite denominators. So, you are multiplying across the proportion.
After cross multiplying you get 10*10 = 8n.
Solving For n
Now, we can use algebra to find n.
100 = 8nJust, divide both sides by 8.
[tex]n=\frac{100}{8}[/tex]Then, simplify.
[tex]n=\frac{25}{2}[/tex]Checking The Answer
To check your answer all you have to do is plug n back into the equation.
[tex]\frac{10}{8}=\frac{25/2}{10}[/tex]This can be rewritten as
[tex]\frac{10}{8}= \frac{25}{2} *\frac{1}{10}[/tex]Then, the right side can be solved.
[tex]\frac{10}{8}= \frac{10}{8}[/tex]
