Answer:

$104.31

Step-by-step explanation:

First let's calculate the sale price of the shoes. If they are 24% off, that means they will be worth 76% of the initial price. So, we can multiply 76% by 129 to find the sale price:

129 * 0.76 = 98.04

The sale price is $98.04. To find the value of the sales tax, multiply the sale price by the percentage of the sales tax:

98.04 * 0.064 = 6.27456

The sales tax rounds to 6.27. Finally, to find the total price, add the value of the sales tax to the sale price:

98.04 + 6.27 = 104.31

The total price Zach will pay is $104.31.

Answer:

3.87 miles

Step-by-step explanation:

The attached figure gives the relative locations of the courthouse, the library and the pool.

The three locations represent a right triangle with the distance between courthouse - pool as the hypotenuse and the distance between courthouse - library as the vertical leg

By the Pythagorean theorem if c is the hypotenuse and a, b the other two legs

\(c^2 = a^2 + b^2\)

a = distance between courthouse and library = 7 miles
c = distance between courthouse  and pool = 8 miles
and we have to find b

So plugging in known values
\(8^2 = 7^2 + b^2\\\\b^2 = 8^2 - 7^2\\\\b^2 = 64 - 49\\\\b^2 = 15\\\\b= \sqrt{15} = 3.87298 \approx 3.87 \;miles\)

The price that Maura sell each scarf would be =$33. Maura sells each scarf for $33. That is option A.

To calculate the amount of money that Maura spends on each scarf the following is carried out.

The amount of money that she spends on the scarf material = $5.50

The percentage selling price of each scarf = 600% of $5.50

That is ;

= 600/100 × 5.50/1

= 3300/100

= $33.

Therefore, each price that is sold by Maura would probably cost a total of $33.

a. The function h(x) is undefined for x = 0 and x = ±√7.

b. These values correspond to vertical asymptotes for the function h(x).

c. The function h(x) has a hole at x = 0.

d. The limit of h(x) as x approaches 0 is either positive infinity or negative infinity, depending on the direction from which x approaches 0.

A function is an association between inputs in which each input has a unique link to one or more outputs.

To determine the behavior of the function h(x) = (4x² + 9x²) / (-x³ + 7x), let's analyze each question separately:

i) The function h(x) is undefined when the denominator equals zero since division by zero is undefined. Thus, we need to find the value(s) of x that make the denominator, (-x³ + 7x), equal to zero.

-x³ + 7x = 0

To find the values, we can factor out an x:

x(-x² + 7) = 0

From this equation, we see that x = 0 is a solution, but we also need to find the values that make -x² + 7 equal to zero:

-x² + 7 = 0

x² = 7

x = ±√7

So, the function h(x) is undefined for x = 0 and x = ±√7.

ii)  A vertical asymptote occurs when the denominator approaches zero, but the numerator does not. In other words, we need to find the values of x that make the denominator, (-x³ + 7x), equal to zero.

From the previous analysis, we found that x = 0 and x = ±√7 make the denominator zero. Therefore, these values correspond to vertical asymptotes for the function h(x).

iii) A hole in the function occurs when both the numerator and denominator have a common factor that cancels out. To find the values of x that create a hole, we need to factor the numerator and denominator.

Numerator: 4x² + 9x² = 13x²

Denominator: -x³ + 7x = x(-x² + 7)

We can see that x is a common factor that can be canceled out:

h(x) = (13x²) / (x(-x² + 7))

Therefore, the function h(x) has a hole at x = 0.

iv) To simplify the expression and find the limit of h(x) as x approaches 0, we can factor out common terms from both the numerator and denominator.

h(x) = (4x² + 9x²) / (-x³ + 7x)

We can factor out x² from the numerator:

h(x) = (4x² + 9x²) / (-x³ + 7x)

    = (13x²) / (-x³ + 7x)

Now, we can cancel out x² from both the numerator and denominator:

h(x) = (13x²) / (-x³ + 7x)

    = (13) / (-x + 7/x²)

Next, we substitute x = 0 into the simplified expression:

lim x→0 (13) / (-x + 7/x²)

Now, we can evaluate the limit by substituting x = 0 directly into the expression:

lim x→0 (13) / (-0 + 7/0²)

    = 13 / (-0 + 7/0)

    = 13 / (-0 + ∞)

    = 13 / ∞

The result is an indeterminate form of 13/∞. In this case, we can interpret it as the limit approaching positive or negative infinity. Therefore, the limit of h(x) as x approaches 0 is either positive infinity or negative infinity, depending on the direction from which x approaches 0.

The main difference between a short futures contract and an option is the obligation involved. In a short futures contract, the seller is obligated to deliver the underlying asset at a predetermined price and date, regardless of market conditions.

In contrast, an option provides the buyer with the right, but not the obligation, to buy (call option) or sell (put option) the underlying asset at a specified price and date. Both short futures contracts and options are derivative financial instruments that allow investors to speculate on price movements, but options provide more flexibility as they do not carry the same obligation as futures contracts.

Obligation: In a short futures contract, the seller (short position) is obligated to deliver the underlying asset at a specified price and date in the future.

Potential Profit/Loss: The seller profits if the price of the underlying asset decreases, but faces losses if the price increases.

Market Exposure: The seller is exposed to unlimited downside risk, as there is no cap on potential losses.

Margin Requirements: Sellers need to maintain margin accounts to cover potential losses and ensure contract performance. Futures contracts require the seller to deliver the asset, while options provide the buyer with the right, but not the obligation, to buy or sell. Options offer more flexibility but come with a premium cost, while futures contracts have unlimited downside risk and require margin accounts.

Answer: 96%

Step-by-step explanation:

Morgan's average grade was 92% after the third test.

Lets say all the tests were out of 100 to help you understand.

We can say that she got 92 out of 100 on all three tests.

Her total point would be 92 * 3 which would be 276, out of 300 points available.

Now she takes her fourth test and she wants an average of 93

Out of 100, if she gets a score of X, her total point after the fourth test would be 276 + X out of 400 points available.

so the percentage of 276 + X / 400 should be 93%.

( 276 + X / 400 ) * 100% = 93%

multiply 400 on each side,

( 276 + X ) * 100 % = 93 * 400 %

now divide each side by 100

276 + X = 93 * 4

93 * 4 = 372

Subtract each side by 276

X = 96

So she needs to get a 96 out of 100 or higher, which is 96%.

Step-by-step explanation:

Perimeter is the distance around the outside of the shape. Add up all the sides. See image.

The statement should be: "On its domain, the curve Y = f(x) attains its maximum value at X = 0 and does not have a minimum value."

To determine the maximum and minimum values of the function f(x) = \(20x^2e^{(-3x)\) on the domain [0, ∞), we can analyze its behavior.

First, let's consider the limits as x approaches 0 and as x approaches infinity:

As x approaches 0, the term \(20x^2\) approaches 0, and the term \(e^{(-3x)\)approaches 1 since \(e^{(-3x)\) is continuous. Therefore, the overall function approaches 0 as x approaches 0.

As x approaches infinity, both terms \(20x^2\) and \(e^{(-3x)\) tend to 0, but the exponential term decreases much faster. Thus, the overall function approaches 0 as x approaches infinity.

Since the function approaches 0 at both ends of the domain and the exponential term dominates the behavior as x increases, there is no maximum value on the domain [0, ∞). However, since the function is always positive, it does not have a minimum value either.

11.7b

Step-by-step explanation:

If you do 339.30 divided by 29 it equals 11.7 but the full equation would be c=11.7b

The proportional equation for the total cost 'c' in terms of the number of boxed lunches 'b' is:

c = (339.30 / 29) * b

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

Let's assume that each boxed lunch costs the same amount, denoted by the variable 'x'.

We are given that the company ordered 29 boxed lunches for a total cost of $339.30. Therefore, we can write the equation:

29x = 339.30

To find the cost 'c' for any number 'b' of boxed lunches, we can set up a proportion:

29x / 29 = 339.30 / b

Simplifying this equation, we get:

x = 339.30 / 29

Now, we can substitute this value of 'x' back into the equation:

c = bx = b * (339.30 / 29)

Therefore, the proportional equation for the total cost 'c' in terms of the number of boxed lunches 'b' is:

c = (339.30 / 29) * b

Londell needs to deliver newspapers for 24 weeks to have enough money to buy the bicycle.

Londell currently has $40 saved, and he needs a total of $400 to buy the bicycle. Each week, he earns $15 delivering newspapers.

To calculate the number of weeks Londell needs to work, we can set up an equation:

$40 (current savings) + $15 (weekly earnings) × (number of weeks) = $400 (total cost of the bicycle)

Simplifying the equation:

$40 + $15 = $400

Subtracting $40 from both sides of the equation:

$15 = $400 - $40

$15 = $360

Dividing both sides of the equation by $15:

= $360 / $15

≈ 24

Therefore, Londell will have to deliver newspapers for approximately 24 weeks to have enough money to buy the bicycle.

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg

What is a unit amount in math?

When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio

1 k + 6.6 k = 617.3

Where “k” is a constant value, a multiplier.

Solving for k:

7.8 k = 617.3

k = 617.3 /7.8  

k= 79.17

So:

Amount of onion used:

Answer:

The number of hours Moran wold have driven before Andre catches up with him is 14 hours

Step-by-step explanation:

The given information are;

The speed with which Andre will drive = 70 miles per hour

The speed with which Morgan will drive = 55 miles per hour

The time of departure of Morgan = 3 hours before Andre departs

Let the time at which Andre catches up with Morgan be, t

We have, from the definition of distance traveled;

Distance traveled =Speed × Time

The distance Morgan would have driven in t hours = 55 × t

Given that to catch up with Morgan, Andre has to travel the same distance, and that Andre starts 3 hours late, we have;

The distance Andre would  drive when Morgan has driven for t hours = 70 × (t - 3)

Therefore, since the distance at the point they meet is the same distance for them both, we have;

55 × t = 70 × (t - 3)

55 × t = 70 × t - 210

210 = 70 × t - 55 × t  = 15 × t

t = 210/15 = 14 hours

Therefore, Morgan would have driven for 14 hours before Andre catches uo with him.
