Answer:
So, Darmal needs to work more than 8.96 hours to earn more than $128.
Step-by-step explanation:
The situation represented by the inequality 14.25x > 128 is B. Darmal earns $14.25 per hour at his job. How many hours does he need to work to earn more than $128?
The inequality states that the product of 14.25 and x (representing the number of hours worked) is greater than 128. Solving for x, we can find the number of hours Darmal needs to work to earn more than $128:
14.25x > 128
x > 128 / 14.25
x > 8.96
So, Darmal needs to work more than 8.96 hours to earn more than $128.
A guy wire supporting a radio tower is positioned 145 feet up the tower. It forms a 45 angle with the ground. To the nearest tenth, about how long is the wire?.
The approximate length of the guy wire supporting the radio tower, as determined using trigonometry with the given information of a 45 degree angle and a height of 145 feet up the tower, is 145 feet.
We can use trigonometry to solve this problem. Let's call the length of the guy wire "x". The opposite side of the right triangle formed by the guy wire and the ground is 145 feet (the height of the tower where the guy wire is attached), and the angle opposite the guy wire is 45 degrees.
Using the trigonometric function tangent, we can set up the following equation:
[tex]tan(45)[/tex] = opposite / adjacent
where "opposite" is 145 feet and "adjacent" is the length of the guy wire, x. Simplifying this equation, we get:
1 = 145 / x
Multiplying both sides by x, we get:
x = 145
Therefore, the length of the guy wire is approximately 145 feet to the nearest tenth.

What is the percentage increase in the estimated number of millionaire households from 2017 to 2018 ? Round to the nearest tenth of a percent
Answer:
Step-by-step explanation:
To calculate the percentage increase in the estimated number of millionaire households from 2017 to 2018, we need to follow these steps:
Determine the estimated number of millionaire households in 2017 and 2018. Let's call these numbers A and B, respectively.
Subtract the 2017 number from the 2018 number: B - A = C
Divide the result from step 2 by the 2017 number: C / A = D
Multiply the result from step 3 by 100 to convert it to a percentage: D * 100 = E
Round the result from step 4 to the nearest tenth of a percent.
In this case, we are given the percentage increase, so we can skip steps 1-4 and simply round the given percentage increase to the nearest tenth of a percent.

A typical glass of wine contains about 22 grams of alcohol. Consider a 103-pound woman, with approximately 6 liters (6000 milliliters) of blood, who drinks two glasses of wine. Complete parts (a) and (b) below.
If all the alcohol were immediately absorbed into her bloodstream, what would her blood alcohol content be? (Round to two decimal places as needed.) g/100 mL
Answer: The amount of alcohol the woman consumed can be calculated as follows:
Two glasses of wine * 22 grams of alcohol per glass = 44 grams of alcohol
To convert this amount to milliliters, we need to know the concentration of the alcohol, which is typically around 12% for wine. So, 44 grams of alcohol is equivalent to 44 grams / 0.12 g/mL = 367 mL.
Next, we can calculate the woman's blood alcohol content (BAC) using the following formula:
BAC = (Alcohol consumed in mL) / (Blood volume in mL) * 100%
The blood volume for a 103-pound woman with approximately 6 liters of blood can be estimated as follows:
6 liters * 1000 mL/liter = 6000 mL
So, the BAC can be calculated as follows:
BAC = (367 mL) / (6000 mL) * 100% = 0.0612 * 100% = 6.12%
Therefore, the woman's blood alcohol content would be 6.12% if all the alcohol were immediately absorbed into her bloodstream.

Select the correct answer. A line t runs downward to the right through two parallel horizontal lines a and b, forming 8 angles numbered from 1 to 8. In the diagram, transversal t cuts parallel lines a and b. Which equation is necessarily true? A. m∠1 = m∠7 B. m∠3 = m∠6 C. m∠5 + m∠8 = 90° D. m∠6 + m∠7 = 180°
Answer:
Step-by-step explanation:
The correct answer is D. m∠6 + m∠7 = 180°.
When a transversal cuts two parallel lines, corresponding angles are equal and alternate interior angles are supplementary. This means that the sum of alternate interior angles is equal to 180°. In this diagram, ∠6 and ∠7 are alternate interior angles, so it is necessarily true that m∠6 + m∠7 = 180°.
The other options are not necessarily true. Option A states that m∠1 = m∠7, but this is only true if the two lines being cut by the transversal are perpendicular. Option B states that m∠3 = m∠6, but this is only true if the two lines being cut by the transversal are parallel. Option C states that m∠5 + m∠8 = 90°, but this is only true if the two lines being cut by the transversal are perpendicular.
You (or your parents) are debating about whether to buy a new car for $19,072.00 or a used car for $15,635.00. Sales tax is 4.5%. You (or your parents) plan to make a down payment of $1,200.00 and your credit rating is fair. What is the difference in interest accrued by the end of the first month?
The difference in the interest accrued by the end of the first month, given the credit rating and the cost is $ 21. 97
How to find the difference ?First, find the amount borrowed to pay for the new car or the used car.
New car :
= ( 19, 072 x ( 1 + 4. 5 % sales tax )) - 1, 200 down payment

Question 4
Component of mix Year 1 Year 2 Standard weight
A Po Pn W
3.00 6.00 16
B 6.80 8.50 6
C 20.80 17.68 2
Using information in the table above, Compute the weighted average of relatives and the weighted average price index.
The weighted average price index is 171, which means that the average price of the components in Year 2 was 171% of their average price in Year 1.
How to find the weighted average price index?To compute the weighted average of relatives, we need to find the weighted average of the ratio of the prices of each component in Year 2 to Year 1. Let's call this ratio the "relative price".
Relative price for component A = Po Year 2 / Po Year 1 = 6.00 / 3.00 = 2.00
Relative price for component B = Pn Year 2 / Pn Year 1 = 8.50 / 6.80 = 1.25
Relative price for component C = Pn Year 2 / Po Year 1 = 17.68 / 20.80 = 0.85
Next, we'll find the weighted average of the relatives by summing the product of each relative price and its corresponding standard weight, and dividing by the sum of the standard weights.
Weighted average of relatives = (2.00 * 16 + 1.25 * 6 + 0.85 * 2) / (16 + 6 + 2)
= (32 + 7.5 + 1.7) / 24
= 41.2 / 24
= 1.71
The weighted average of relatives is 1.71, which means that the average price of the components increased by 71% from Year 1 to Year 2.
To compute the weighted average price index, we'll use the weighted average of relatives as a reference point and multiply it by 100.
Weighted average price index = Weighted average of relatives * 100
= 1.71 * 100
= 171
Therefore the weighted average price index is 171, which means that the average price of the components in Year 2 was 171% of their average price in Year 1.

what is the pattern for each hypotenuse in the pythagorean spiral?
i have:
Hypotenuse = (Triangle # + 1) X 9
(square root the answer)
does this make sense?
The pattern for the hypotenuse in the Pythagorean spiral is √(a² + b²)
How to get the patternThe Pythagorean spiral is formed by drawing squares whose side lengths are given by the Pythagorean triples, which are sets of three positive integers (a, b, c) that satisfy the equation a² + b² = c².
In the Pythagorean spiral, the hypotenuse of each square is the diagonal of the square, which is given by the square root of the sum of the squares of the sides. For a square with side lengths a and b, the hypotenuse (diagonal) is given by:
√(a² + b²)
Since the side lengths of each square in the Pythagorean spiral are given by the Pythagorean triples, the hypotenuse of each square can be calculated using the Pythagorean theorem. Therefore, the pattern for each hypotenuse in the Pythagorean spiral is that it is given by the square root of the sum of the squares of the side lengths, where the side lengths are integers that form a Pythagorean triple.

An assiatant receies a 10% raise, bringing the salary to 47,585. What was the salary before the raise?
Answer:
Step-by-step explanation:
here's a more detailed explanation:
The assistant received a raise of 10%, which means that their salary increased by 10% of the original salary. The new salary after the raise is given as 47,585.
To find the original salary before the raise, we need to reverse the effect of the raise. To do this, we divide the new salary by the factor that represents the increase, which is 1 plus the raise as a decimal.
The raise as a percentage is 10%, which is equivalent to 0.10 as a decimal. Therefore, the factor that represents the increase is 1 + 0.10 = 1.10.
We can now use this factor to find the original salary by dividing the new salary by the factor:
Original salary = New salary / (1 + Raise as a decimal)
Original salary = 47,585 / (1 + 0.10)
Original salary = 47,585 / 1.10
Original salary = 43,259.09
So the salary before the raise was 43,259.09.

The derivative of the composite function f(x) = (3 · x · cos x + √x) / [5 · x² · (sin x + 1)] is equal to f'(x) = [[3 · cos x - 3 · x · sin x + (1 / 2√x)] · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · [5 · x · (sin x + 1) + 5 · x² · cos x]] / [5 · x² · (sin x + 1)]².
How to determine the derivative of a composite function
In this problem we must determine the derivative of the composite function f(x) = (3 · x · cos x + √x) / [5 · x² · (sin x + 1)]. This can be done by using the following derivative rules:
Derivative of the addition of two functions
d [f(x) + g(x)] / dx = df(x) / dx + dg(x) / dx
Derivative of the product of two functions
d [f(x) · g(x)] / dx = [df(x) / dx] · g(x) + f(x) · [dg(x) / dx]
Derivative of the division of two functions
d[f(x) / g(x)] / dx = [[df(x) / dx] · g(x) - f(x) · [dg(x) / dx]] / [g(x)]²
Derivative of a function and a constant
d [c · f(x)] / dx = c · df(x) / dx
Derivative of a power function
d [xⁿ] / dx = n · xⁿ⁻¹
Derivative of cosine
d [cos x] / dx = - sin x
Derivative of sine
d [sin x] / dx = cos x
Now we proceed to determine the derivative of the function by derivative rules:
f'(x) = [d [3 · x · cos x + √x] / dx · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · d [5 · x² · (sin x + 1)] / dx] / [5 · x² · (sin x + 1)]²
f'(x) = [[3 · cos x - 3 · x · sin x + (1 / 2√x)] · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · [5 · x · (sin x + 1) + 5 · x² · cos x]] / [5 · x² · (sin x + 1)]²

You asked the players to shoot the ball on the targets 4 times. You added that if
they hit one of the targets, they get the target points.
Test 1:
Messi shot the ball. His ball followed the path of the equation where x is the target
points:
3(3x - 4) = 24
6.8 (2.3x + 5.7) = 132.6
The first equation 3(3x - 4) = 24 can be solved for x as follows:
3(3x - 4) = 24
9x - 12 = 24
9x = 36
x = 4
So, if Messi hit the target, he would score 4 points.
The second equation 6.8 (2.3x + 5.7) = 132.6 can be solved for x as follows:
6.8 (2.3x + 5.7) = 132.6
2.3x + 5.7 = 132.6 / 6.8
2.3x + 5.7 = 19.55
2.3x = 13.85
x = 6
So, if Ronaldo hit the target, he would score 6 points.
