a boat is 180 in Long in private plane is 85% longer than the boat how long is the plane
Answer:
The length of the plane is 333 in.
Step-by-step explanation:
Plane length = (1.85)(Boat length)
The 0.85 in (1.85) above represents the added length; the (1.85) represents the length of the boat PLUS 0.85 time the length of the boat.
Plane length is (1.85)(Boat length) = 1.85(180 in) = 333 in
The length of the plane is 333 in.

Judy is working at a retail store over summer break. A customer buys a $50 shirt that is on sale
for 20% off. Judy computes the discount, adds sales tax of 10%, and tells the customer how
much he owes. The customer insists that Judy first add the sales tax and then apply the discount.
He is convinced that this way he will save more money because the discount amount will be
larger.
Answer:
Same final price, no differenceStep-by-step explanation:
Way 1, final price
Apply discount and then apply tax
(50 - 20%) + 10% =50*0.8*1.1 = $44Way 2, final price
Apply tax and then apply discount
(50 + 10%) - 20% = 50*1.1*0.8 = $44As we see both ways reveal same final price so no difference
Answer:
It does not matter in which order the discount and tax are computed.
Step-by-step explanation:
Judy first takes 20% off which gives a new price of $50(0.8)=$40. She then adds the 10% sales tax for a final price of $40(1.1)=$44. The customer first adds 10% for a new price of $50(1.1)=$55. He then takes 20% off for a final price of $55(0.8)=$44.
The customer is right to say that the discount amount will be larger, it is $11 opposed to $10 with his method. But the additional $1 just gets subtracted from the tax amount that was added in the first step. So the final price is the same in both cases.

mass of water vapor (g) / mass of dry air (kg)
is the humidity measure of....
-the mixing ratio.
-relative humidity.
-vapor pressure.
-absolute humidity.
The mass of water vapor (g) / mass of dry air (kg) is the humidity measure of the mixing ratio
The mixing ratio is defined as the mass of water vapor in grams divided by the mass of dry air in kilograms in a mixture of air and water vapor. It is a useful parameter for meteorologists and atmospheric scientists to describe the amount of water vapor in the atmosphere, particularly in the upper atmosphere where the relative humidity may be very low.
Relative humidity is the ratio of the partial pressure of water vapor in the air to the equilibrium vapor pressure at a given temperature and pressure, expressed as a percentage. Vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Absolute humidity is the mass of water vapor per unit volume of moist air.

Ileana have to invest for 8 years :
What is Simple interest?Simple interest is a simple and straightforward formula for figuring out how much interest will be charged on a loan. Simple interest is calculated by dividing the daily interest rate by the principle and the number of days between payments.
How do you calculate simple interest?The principal amount must be multiplied by the time, interest rate, and time period in order to calculate simple interest. Simple Interest = Principal x Interest Rate x Time is the written formula.
Given Data:Principal amount = $15,500
interest = $5,084
Time = ?
Rate = 4.1% simple interest
Solution:to find the simple interest :
I = \(\frac{(p*t*r)}{100}\)
Then:
Time = \(\frac{I*100}{P*R}\)
= \(\frac{(5084*100)}{(15500*4.1)}\)

3.Match each function notation with the transformation that has been performed:A._______ B._______ C._______ D._______ E._______ F._______A. f(x-3)B. f(-x)C. 2f(x)D. -f(x)F. f(x)+2G. f(3x)U. Horizontal translationV. Vertical translationW. Horizontal compressionX. Vertical stretchY. X-axis reflectionZ. Y-axis reflection
So,
First, remember that:
Given a function f(x). If we make the following changes to it (where c is a number), they will represent:
1. Horizontal translation.
\(f(x\pm c)\)The expression above represents a horizontal translation.
So, if we have f (x - 3) this is a horizontal translation 3 units to the right.
If the sign is positive, the graph moves to the left and if it's negative, it moves to the right.
2. Vertical translation:
\(f(x)\pm c\)The expression above represents a vertical translation.
So, if we have f(x) + 2, this change represents a vertical translation 2 units up.
If the sign is positive, the graph moves c units up, and if it is negative, the graph moves c units down.
3. X-axis reflection.
\(-f(x)\)The expression above represents a X-axis reflection.
So, given -f(x), that's a reflection over the x-axis.
4. y-axis reflection.
\(f(-x)\)The expression above represents a y-axis reflection.
So, given f(-x), that's a reflection over the y-axis.
5. Horizontal compression:
\(f(cx)\)If |c| is greater than 1, this is a horizontal compression.
If |c| is between 0 and 1, this is a horizontal stretch.
In our problem, we are given f(3x), and, as 3 is greater than 1, we have a horizontal compression.
6. Vertical stretch:
\(cf(x)\)If |c| is greater than 1, this is a horizontal compression.
If |c| is between 0 and 1, this is a horizontal stretch.

In the third blank column, write down a lim f(x) = x value of x and f(x) (any value you want) that would refute the claimx→5-
The statement "Since
f(5)
is undefined,
lim f(x) = [infinity]"
is incorrect. The reason for this is that the existence of the limit requires that the function approaches a specific value as x approaches a certain point, not that the function is defined at that point.
The student's statement is incorrect because it assumes that since f(5) is undefined, the limit of f(x) as x approaches 5 must be infinity. However, the existence of the limit does not depend on the value of the function at that particular point.
Based on the values given in the table, it is evident that as x approaches 5 from the left, f(x) tends to increase without bound (evidenced by the increasing values of f(x) as x approaches 5 from the left). However, as x approaches 5 from the right, f(x) tends to decrease without bound (evidenced by the decreasing values of f(x) as x approaches 5 from the right). This inconsistency suggests that the limit of f(x) as x approaches 5 does not exist.
In the first blank column, we can choose a value of x and f(x) that would support the claim lim f(x) = [infinity]. For example, we can select x = 10 and f(10) = 100, where f(x) tends to increase significantly as x gets larger.
In the second blank column, we can choose a value of x and f(x) that would refute the claim lim f(x) = [infinity]. For example, we can select x = 3 and f(3) = -100, where f(x) tends to decrease significantly as x gets smaller.
Based on the table, including the chosen values, it would be reasonable to conclude that lim f(x) as x approaches 5 does not exist since the function does not approach a specific value from both the left and right sides of x = 5. The values of f(x) for x approaching 5 from different directions do not exhibit a consistent pattern, suggesting that the limit does not converge to a single value.

Brandon has 36000 to invest and wants to earn 5% interest per year. He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year. How much money should he put into each account so that he earns 5% annually
Answer:
The money in an account that earns 4.4% interest per year = 22500
The rest into an account that earns 6% interest per year = 13500
Step-by-step explanation:
Interest = Principal × Rate × Time
Let x = money saved in account A
Let y = money saved in account B
Brandon has 36000 to invest and wants to earn 5% interest per year
x + y = 36000..... Equation 1
x = 36000 - y
He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year.
Hence:
4.4% × x × 1 + 6% × y × 1 = 36000 × 5% × 1
0.044x + 0.06y= 1800....... Equation 2
Substitute 36000-y for x in Equation 2
0.044(36000 - y) + 0.06y = 1800
1584 -0.044y + 0.06y = 1800
-0.044y + 0.06y = 1800 - 1584
0.016y = 216
y = 216/0.016
y = 13500
Note that:
x = 36000 - y
x = 36000 - 13500
x = 2250
Therefore,
The money in an account that earns 4.4% interest per year = 22500
The rest into an account that earns 6% interest per year = 13500

Suppose you have an outdoor pool measuring 25 ft by 10ft . You want to add a cement walkway around the pool. If the walkway will be 1 ft thick and you have 304 ft³ of cement, how wide should the walkway be?
The area covered by the pool and the cement walkway is 304 square feet. The width of the walkway would be 5 feet
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
Let x be represent the width of the walkway.
The pool measures 25 ft by 10ft . If the walkway must have a uniform width around the entire pool, then the total length of the pool and the walkway = 25+ x + x = 25 + 2x
The total width of the pool and the walkway = 10 + x + x = 10 + 2x
The area covered by the pool and the cement walkway is 304 square feet. This means that;
(25 + 2x)(10 + 2x) = 304
250 + 50x + 20x + 4x^2 = 304
4x^2 + 70x + 250 - 304 = 0
4x^2 + 70x - 54 = 0
x(x + 20) - 5(x + 20) = 0
(x - 5)(x + 20) = 0
x = 5 or x = - 20
Thus The width cannot be negative.
Therefore, the width of the walkway is 5 feet.
