Answer:

$18.15

Step-by-step explanation:

We have been given that in Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Yuki is purchasing a handbag priced at \$220$220 before tax.

To find total sales tax paid by Yuki for her handbag purchase we will find 4.6% of $220 and 3.65% of $220 and add amount of both taxes.  

[tex]\text{Total sales tax amount}=\text{State sales tax amount+ County sales tax amount}[/tex]

[tex]\text{States sales tax amount for handbag}=\frac{4.6}{100}*220[/tex]

[tex]\text{States sales tax amount for handbag}=0.046*220[/tex]

[tex]\text{States sales tax amount for handbag}=10.12[/tex]

Now let us find county sales tax for handbag purchase.

[tex]\text{County sales tax amount for handbag}=\frac{3.65}{100}*220[/tex]

[tex]\text{County sales tax amount for handbag}=0.0365*220[/tex]

[tex]\text{County sales tax amount for handbag}=8.03[/tex]

Now let us add both amount to get total tax paid by Yuki.

[tex]\text{Total sales tax}=10.12+8.03[/tex]

[tex]\text{Total sales tax}=18.15[/tex]

Therefore, Yuki paid $18.15 sales tax for her handbag purchase.    

Answer:

Each shirt costs $22.95

Step-by-step explanation:

39.58 + 52.22 = 91.80

91.80/4= 22.95

Final answer:

Caitlan bought 4 shirts for a total cost of $91.80. Therefore, the price of each shirt was $22.95.

Explanation:

To find the price of each shirt Caitlan bought, we can use the equation:

x - 39.58 = 52.22

where x represents the total cost of the shirts before the store credit is applied. To solve for x, we can add 39.58 to both sides of the equation:

x = 52.22 + 39.58 = 91.80

Since Caitlan bought 4 shirts, we can divide the total cost by 4 to find the price of each shirt:

91.80 / 4 = 22.95

Therefore, the price of each shirt Caitlan bought was $22.95.

If the manager buys 2 or more chairs then he saves 31.99 dollars on each chair.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A manager needs to buy chairs for his office the price for 1 chair is 79.99 dollars.

If the manager buys 2 or more chairs then he get's a 40% discount on each chair.

Therefore, He saves 40% of the original cost of 1 chair which is,

= (40/100)×79.99.

= 31.99 dollars.

So, The manager saves 31.99 dollars on each chair if he buys 2 or more at a time.

Three-point Turns

Three-point turns are typically used to reverse direction on narrow, two-lane roads. They are tricky due to the narrowness of the road and the fact that your car completely blocks all traffic flow during part of the procedure.

Two-point turns (left side)*

If we’re going to get technical, then I must put a qualifier to these types of turns. Many driver’s ed professionals call these two-point turns and I have to agree albeit with an asterisk. Most professionals reserve three point turns for those turns which reverse direction on narrow streets without the aid of a side street. Therefore, any turn that reverses direction with the aid of a side street would be a two-point turn.

Answer:

[tex]\dfrac{3}{5}[/tex] of the height makes up the height.

Step-by-step explanation:

The length of an aquarium, which has the form of a rectangular solid, is [tex]5\ dm[/tex]

The width is [tex]\dfrac{4}{5}[/tex] of the length, so teh width is,

[tex]=5\times \dfrac{4}{5}=4\ dm[/tex]

Let us assume the height is 'h' dm.

So the volume will be,

[tex]=\text{Length }\cdot \text{ Width }\cdot\text{ Height}[/tex]

[tex]=5\times 4\times h[/tex]

[tex]=20h\ dm^3[/tex]

As 1 liter of water occupies volume of  1 dm³, so volume of 40 liters of water will be,

[tex]=40\times 1=40\ dm^3[/tex]

This [tex]40\ dm^3[/tex] is the [tex]\dfrac{2}{3}[/tex]th of total volume.

Hence total volume will be,

[tex]=\dfrac{40}{\frac{2}{3}}=40\times \dfrac{3}{2}=60\ dm^3[/tex]

Therefore,

[tex]\Rightarrow 20h=60[/tex]

[tex]\Rightarrow h=3\ dm[/tex]

Answer:

option A) New cars and used cars is correct option.

Step-by-step explanation:

loan Interest rate can be defined as the percentage of a loan paid by borrowers to lenders. For most loans, interest is paid in addition to principal repayment in order to compound over time.

since new cars have  more price than old cars that's why new cars have more greater loan interest than old cars

hence option a is correct

There is generally a significant difference in loan interest rates between new cars and used cars, with new cars usually having lower rates. Institutions regard new cars as less risky than used or refinanced cars, hence, they tend to offer lower interest rates to encourage new car loans.

There is typically a significant difference in loan interest rates between new cars and used cars. This is mainly because new cars tend to have lower interest rates than used cars. Financial institutions, such as banks and credit unions, usually perceive new cars as less risky because they have not been subjected to any wear and tear compared to used cars which could potentially have mechanical issues. Consequently, these institutions lower the interest rates for new car loans to encourage more borrowers.
Whereas, in the case of used cars and refinanced cars, the interest rates are significantly higher due to the increased risk that the lender has to take on.

The equation [tex]\(14,000 = 8 \cdot 2^{x+y}\)[/tex] correctly represents the area of the wildfire in terms of x and y (option C).

How to find the correct equation for the area in terms of x and y?

The initial size of the wildfire is 8 square feet.

It doubles its width every x hours, so the width grows by a factor of [tex]\(2^{\frac{1}{x}}\)[/tex] each hour.

It doubles its length every y hours, so the length grows by a factor of [tex]\(2^{\frac{1}{y}}\)[/tex] each hour.

The area (A) of a rectangle is given by the formula [tex](A = \text{length} \times \text{width}\))[/tex].

So, after a period of time, the area of the wildfire is given by:

[tex]A = 8 \times 2^{\frac{1}{x}} \times 2^{\frac{1}{y}}[/tex]

Combine the exponents:

[tex]A = 8 \times 2^{\frac{1}{x} + \frac{1}{y}}[/tex]

Now, if the area is 14,000 square feet, we can set up the equation:

[tex]14,000 = 8 \times 2^{\frac{1}{x} + \frac{1}{y}}[/tex]

To make it match one of the given options, we can express 8 as 2³:

[tex]\[ 14,000 = 2^3 \times 2^{\frac{1}{x} + \frac{1}{y}} \][/tex]

Combine the exponents again:

[tex]\[ 14,000 = 2^{3 + \frac{1}{x} + \frac{1}{y}} \][/tex]

So, the correct equation that represents the area of the wildfire in terms of x and y is:

[tex]\[ 14,000 = 8 \times 2^{x+y} \][/tex]

Therefore, option C. [tex]\(14,000 = 8 \cdot 2^{x+y}\)[/tex] is the correct representation.

Answer: (C) 108

Step-by-step explanation:

The corresponding angle to x and (x - 36) form a linear pair, which means they are supplementary angles, hence their sum is 180°

(x) + (x - 36) = 180

2x - 36 = 180

2x         = 216

 x         = 108

Answer:

The Answer is 108

Step-by-step explanation:

Few things to Note:

180 angles are linear (so two angles in straight line ADDS UP to makes 180 degree)

Corresponding angles equal each other (aka the two angles shown is corresponding..meaning BOTH are "x"; also, this problem tells you that)

Knowing this, x-36 and its adjacent(angle next to it) is x and they are on a 180 straight line, set equation (x-36)+x= 180 and solve

(x-36)+x= 180--->2x-36=180--->216/2=x

Final answer:

To find the height of the parallelogram with an area of 285 square centimeters and a base of 19 centimeters, divide the area by the base, resulting in a height of 15 centimeters.

Explanation:

The question pertains to finding the height of a parallelogram given the area and the base length. The formula for the area of a parallelogram is Area = base × height. Given an area of 285 square centimeters and a base length of 19 centimeters, we can solve for the height by rearranging the formula:

Height = Area / base

By substituting the given values:

Height = 285 cm² / 19 cm = 15 cm

So, the height of the parallelogram is 15 centimeters.

This is an exponential growth problem.

The formula for this is:

y = a(1+rate)^time

a = the starting value = 245,000

Rate is the percent of increase written as a decimal = 7% = 0.07

Time would be the number of years from the starting year to the year you are trying to find: 2020 - 2015 = 5 years

Now you have y = 245000(1 + 0.07)^5

Answer:

461 adults and 864 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 1,325 tickets were purchased, then s+a=1325.

We also know that a total of $3,169 was collected and adult tickets cost $5 each and students cost $1 each. We can write 1s+5a=3169.

We will solve by substituting one equation into the other. We first solve the first equation for s which is s=1325-a. Substitute s=1325-a into 1s+5a=3169. Simplify and isolate the variable a.

1(1325-a)+5a=3169

1325-a+5a=3169

1325+4a=3169

1325-1325+4a=3169-1325

4a=1844

a=461

This means that 461 adults attended and 864 students attended since 864+461=1325.

Answer:

X=3

Step-by-step explanation:

We have two linear functions which intersect at a point. This point is shown in the attached graph. Linear functions are lines which are made of points that satisfy the function or relationship.  This means at the intersection, this point (3,-1), both functions have the same values. An input of x=3 produces y=-1 in both functions.

Final answer:

To find the input value that yields the same output for both functions f(x) = -2/3x + 1 and g(x) = 1/3x - 2, we set the functions equal, combine like terms, and solve for x, getting the result x = 3.

Explanation:

The question asks which input value produces the same output value for the two functions f(x) = -2/3x + 1 and g(x) = 1/3x - 2. To find this value, we need to set the two functions equal to each other and solve for x.

Here are the steps to find the input value:

Set f(x) equal to g(x):
  -2/3x + 1 = 1/3x - 2

Combine like terms:
  -2/3x - 1/3x = -2 - 1

Combine the x coefficients on the left side and constants on the right side:
  -1x = -3

Divide both sides by -1 to solve for x:
  x = 3

Therefore, the input value that produces the same output value for both functions is x = 3.

[tex]=\frac{0.8+1.1+0.9+0.8+1.0+1.2+0.9+1.1+1.0+1.2}{10}\\\\=1[/tex]

Similarly,

Mean radii of unfertilized tomatoes is given by

[tex]\frac{1.4+1.6+1.3+1.5+1.1+1.5+1.6+1.2}{8}\\\\=\frac{11.2}{8}\\\\=1.4[/tex]

So, the difference between the mean radii of fertilized and unfertilized tomatoes will be

[tex]1.4-1=0.4\ cm[/tex]

Hence, Option 'B' is correct.

Nadia gave Pete 11 postcards to balance the numbers as described. This means Pete ended up with 2 more postcards than Nadia after the exchange.

To find out how many postcards Nadia gave to Pete, let's set up some equations based on the information given.

First, let's define the number of postcards Pete has as P.

Since Nadia has 20 more postcards than Pete, we know:

N = P + 20

Now, let's define the number of postcards Nadia gives to Pete as x.

After Nadia gives x postcards to Pete, Nadia will have N - x postcards and Pete will have P + x postcards.

According to the problem, after the exchange, Pete has 2 more postcards than Nadia: P + x = (N - x) + 2

Substitute the first equation (N = P + 20) into the second equation: P + x = ((P + 20) - x) + 2

Simplify the equation:

P + x = P + 20 - x + 2

P + x = P + 22 - x

Now, isolate x on one side of the equation by subtracting P from both sides:

x + x = 22

2x = 22

Divide both sides by 2: x = 11

The function [tex]p(x) = 0.1x+1[/tex] ,   where  x is the depth in meters.

Step-by-step explanation:

As per the statement: The pressure at sea level is 1 atmosphere and increases at a constant rate as depth increases.

Then, we have the two points i,e (0, 1) and (23, 3.3).

An equation of the line is in the form of y=mx+b where m is the slope or rate of the line and b is the y-intercept.

Let x represents the depth in meters and p(x)= y represents the pressure in atmosphere.

Calculate slope of the line:

Slope of line(m) is given by:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the given point we have;

[tex]m = \frac{3.3-1}{23-0} = \frac{2.3}{23} = 0.1[/tex]

Then, our equation of line become:

y = 0.1x + b                           .....[1]

To solve for b;

Substitute the point (0, 1)  in [1];

[tex]1 = 0.1(0)+b[/tex]

[tex]1 = b[/tex]

Our equation for this line become: y = 0.1x +1

Now, we write this for x as a function of p,

i.e, p(x) = 0.1x + 1

Then, the function formula become;

[tex]p(x) = 0.1x+1[/tex] where x is the depth in meters.

10: 2 * 5

22: 2 * 11

99: 3 * 3 * 11

GCF: 1

LCM: 2 * 5 * 11 * 3 * 3

     = 990

The Least Common Multiple (LCM) of the numbers 10, 22, and 99 is found by prime factorization and taking the highest power of all prime factors that appear, which results in an LCM of 990.

To find the Least Common Multiple (LCM) of the numbers 10, 22, and 99, we need to prime factorize each number and then take the highest power of all the prime factors that appear.

Prime factorization of 10 = 2 x 5

Prime factorization of 22 = 2 x 11

Prime factorization of 99 = 32 x 11

Now, identify the highest powers of all prime factors, which are 2, 32, 5, and 11. Then, multiply these together:

LCM = 2 x 32 x 5 x 11 = 2 x 9 x 5 x 11 = 990

Therefore, the LCM of 10, 22, and 99 is 990.
