Step-by-step explanation:
The height of a door is 1.4 feet more than 2.3 times its width. If the height of the door is 8.5 feet, which equation can be used to determine x, the width of the door.
Answer:
[tex]2.3x+1.4=8.5[/tex], width = 3.087 feet.
Step-by-step explanation:
Let as consider width of the door be x feet.
It is given that height of a door is 1.4 feet more than 2.3 times its width. So,
[tex]Height=2.3x+1.4[/tex]
The height of the door is 8.5 feet.
[tex]2.3x+1.4=8.5[/tex]
Therefore, the required equation is [tex]2.3x+1.4=8.5[/tex].
[tex]2.3x=8.5-1.4[/tex]
[tex]2.3x=7.1[/tex]
[tex]x=\dfrac{7.1}{2.3}[/tex]
[tex]x\approx 3.087[/tex]
So, the width of the door is about 3.087 feet.
7:00PM For dinner, you decide to go out to eat at a restaurant with your significant other. The bill is $32.43, and you would like to leave a 20% tip for your waiter. What will the amount of the tip be and what is the final amount of your bill? Remember to round all values to the nearest cent.
Answer:
Tip amount: $6.49
Final amount of the bill: $38.92
Step-by-step explanation:
We need to calculate the tip amount which is 20% of $32.43.
Then we will add the tip amount to $32.43.
To find a percent of a number, change the percent to a decimal by dividing the percent by 100 and multiply by the number.
20% of $32.43 =
= 0.2 * $32.43
= $6.486
We round off the tip amount to the nearest cent, $6.49
The tip amount is $6.49
To find the final amount of the bill, we add the tip amount to the bill amount.
$32.43 + $6.49 = $38.92

Answer:
9.29
Step-by-step explanation:
S₄ is the area using Simpson's rule and 4 intervals.
Simpson's rule can be calculated as:
Sᵢ = Δx/3 (f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + ... + 4f(xᵢ₋₂) + 2f(xᵢ₋₁) + f(xᵢ))
Or, Simpson's rule can be calculated as a combination of midpoint and trapezoid sums:
S₂ᵢ = (2Mᵢ + Tᵢ) / 3
Using the first method:
Δx = (4−0)/4 = 1
S₄ = 1/3 (1.00 + 4(1.41) + 2(2.24) + 4(3.16) + 4.12)
S₄ = 1/3 (27.88)
S₄ ≈ 9.29
Using the second method:
S₄ = (2M₂ + T₂) / 3
The midpoint area for 2 intervals is:
M₂ = (2) (1.41) + (2) (3.16) = 9.14
The trapezoid area for 2 intervals is:
T₂ = ½ (1.00 + 2.24) (2) + ½ (2.24 + 4.12) (2) = 9.60
Therefore:
S₄ = (2 (9.14) + 9.60) / 3
S₄ ≈ 9.29

Which of the following is an odd function? f(x) = 3x2 + x f(x) = 4x3 + 7 f(x) = 5x2 + 9 f(x) = 6x3 + 2x
The odd function from the following function is f(x) = 6x³ + 2x.
What is an odd function?The function f(x) is said to be an odd function if the output value of f(-x) is the same as the negative of f(x) for all values of x in the domain of f.
f(-x) = -f(x)
The functions are given below.
f(x) = 3x² + x
f(x) = 4x³ + 7
f(x) = 5x² + 9
f(x) = 6x³ + 2x
f(x) = 3(-x)² + (-x) = 3x² - x
f(x) = 4(-x)³ + 7 = -4x³ + 7
f(x) = 5(-x)² + 9 = 5x² + 9
f(x) = 6(-x)³ + 2(-x) = -6x³ - 2x = - (6x³ + 2x)

Alkena and Hsu together earn $84,369 per year, If alkena earns $12,468 more per year than Hsu, the how much of them earn per year?
Answer:
Hsu makes $35,950.50 and Alkena makes $48,418.50
Step-by-step explanation:
Create a system of equations, where h is the amount Hsu makes and a is the amount Alkena makes:
a + h = 84,369
a = h + 12,468
Solve by substitution by plugging in h + 12,468 as a:
h + 12,468 + h = 84,369
2h + 12,468 = 84,369
2h = 71,901
h = 35,950.50
Plug this into the equation, a = h + 12,468 , to solve for a
a = 35,950.50 + 12,468
a = 48,418.50
So, Hsu makes $35,950.50 and Alkena makes $48,418.50

Find the midpoint of the segment with the following endpoints.
(-6, -6) and (4, -2)
Answer:
(-1,-4)
Step-by-step explanation:
USE A1 + A2 / 2 AND B1 + B2 / 2
A1 + A2 / 2
= (-6+4) / 2
= -2/2
= -1
B2 + B1 / 2
= (-6+(-2)) / 2
= -8 / 2
= -4
therefore, (-1,-4) is your midpoint.

To find:
The probability that a 4 will come up exactly twice = ?
Solution:
Let 4 comes up exactly twice, let the third number be [tex]x[/tex].
The possible outcomes can be:
([tex]x[/tex], 4, 4) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.
(4, [tex]x[/tex], 4) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.
(4, 4, [tex]x[/tex]) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

Which statement is true about the expression 12 minus 7 + 3? The expression is equivalent to 12 minus (7 + 3) because of the associative property. The expression is equivalent to 12 + 3 + (negative 7) because of the associative property. The expression is equivalent to 12 minus 3 + 7 because of the commutative property. The expression is equivalent to 12 + 3 + (negative 7) because of the commutative property.
Answer:
The Expression is equivalent to 12+3+ negative 7
Step-by-step explanation:
When you sub tract something for example 5-3 the three can be looked at as a negative number. 5-3=2 but 5+ (-3)=2 as well
The associative property indicates that the true statement about the expression is the option;
''The expression is equivalent to 12 + 3 + (negative 7) because of the associative property''
What is the associative property?
The associative property is related to the grouping of the numbers in an operation. According to the associative property changing the grouping of numbers does not change the result of addition and multiplication.
The associative property allows us to change the grouping of the addition operation, so we can rewrite the expression as follows; (12 + 3) + (negative 7), which simplifies to 15 + (negative 7) or 8. The commutative property on the hand, allows us to change the order of the addition operation. However, with regard to the question, it is not relevant because the expression involves addition and subtraction

If C is a constant, and the domain of x is all real numbers, there is no minimum for y. It can approach negative infinity.
We're not sure what you want or what restrictions may exist. The given relation does not suggest any minimum. We'd have to say it Does Not Exist.
