9) Volume of the cone: [tex]9152 mm^3[/tex]

10) New volume of the cone: [tex]339 mm^3[/tex]

11) The volume of the cone shrinks by a factor of [tex]3^3=27[/tex]

12) Volume of the composite  figure: [tex]15 ft^3[/tex]

Step-by-step explanation:

9)

The volume of a cone is given by the equation

[tex]V=\frac{1}{3}\pi r^2 h[/tex]

where

[tex]\pi r^2[/tex] is the area of the base, where

r is the radius of the cone

h is the height of the cone

For the cone in this problem, we have:

r = 18 mm (radius)

h = 27 mm (height)

Therefore, the volume of this cone is

[tex]V=\frac{1}{3}\pi (18)^2 (27)=9152 mm^3[/tex]

10)

In this second exercise, the radius and the height of the cone are divided by 3. Therefore we have:

[tex]r'=\frac{r}{3}=\frac{18}{3}=6 mm[/tex] is the new radius of the cone

[tex]h'=\frac{27}{3}=9 mm[/tex] is the new height of the cone

Therefore, the new volume of the cone is

[tex]V=\frac{1}{3}\pi r'^2 h'[/tex]

And substituting, we find

[tex]V=\frac{1}{3}\pi (6)^2 (9)=339 mm^3[/tex]

11)

We can understand what happened to the volume of the cone after dividing its dimensions by 3 by calculating the ratio of the original volume to the new volume:

[tex]\frac{V}{V'}=\frac{9152}{339}=27[/tex]

This means that the new volume of the cone is 27 times smaller than the original volume.

We see that this "factor of shrinking" corresponds to the total factor of shrinking ofits dimensions, to the power of 3. In fact:

- Each the radius and the height of the cone has shrunk by a factor of 3

- However, the cone is a figure in 3  dimensions, so the total factor of shrinking of its volume is [tex]3^3 = 27[/tex]

12)

The composite figure consists of a squared pyramid + a parallelepiped.

The volume of the square pyramid is given by:

[tex]V_1 = \frac{1}{3}Lwh[/tex]

where

L = 5 ft is the length of the base

w = 1 ft is the width of the base

h = 6 ft is the height of the pyramid

Substituting,

[tex]V_1 = \frac{1}{3}(5)(1)(6)=10 ft^3[/tex]

The volume of the parallelepiped is given by

[tex]V_2=Lwh[/tex]

where

L = 5 ft is the length of the base

w = 1 ft is the width of the base

h = 1 ft is the height

Substituting,

[tex]V_2 = (5)(1)(1)=5 ft^3[/tex]

So, the total volume of the composite figure is

[tex]V=V_1+V_2=10+5=15 ft^3[/tex]

Answer:

Dealer B

Step-by-step explanation:

Maintenance cost per year = 75$

Dealer "A' wants $4.995.00.

Dealer "B" wants 55,595.00 with free maintenance cover for a year.

It is obvious that the best deal is what dealer B is offering, with free maintenance cover per year. for example, if i pick dealer A, calculate the maintenance cover for 3years = $2700

whereas for dealer B, a whole year maintenance cost is free, it implies that one will start paying the next coming year i.e a year lesser than dealer A. by that time the one who picked dealer A must have paid $3600 for maintenance while the one who picked dealer B will about to pay $1800.

The best deal is what dealer B is offering coupled with the free maintenance cover for 1year.

Final answer:

After calculating the total costs for one year, Dealer B offers a better deal on the Jeep by saving $300, as it includes free maintenance, contrasting with Dealer A which results in higher overall costs after adding maintenance payments.

Explanation:

To determine which car deal from the dealers is the better option, we need to calculate the total cost of each option over the course of one year, including the average monthly maintenance cost on a used car. According to AAA, this cost is $75 per month.

For Dealer A, the cost of the car is $4,995 with no free maintenance, so the total cost after one year is the price of the car plus 12 months of maintenance:

Cost of the car: $4,995

12 months of maintenance: 12 * $75 = $900

Total cost for Dealer A after one year: $4,995 + $900 = $5,895

For Dealer B, the car costs $5,595 but comes with free maintenance for one year, which means:

Total cost for Dealer B after one year: $5,595

Comparing these totals, we see that Dealer B offers the better deal, with the overall savings being:

Savings: $5,895 - $5,595 = $300

Answer:

Step-by-step explanation:

When you talk about "unit price," you need to define the unit of interest. Unit prices on grocery store shelves don't always use the same unit, even for like items. Here it might be convenient to use any of the following as the "unit":

The "unit price" is computed as ...

  unit price = (price for some number of units)/(the number of units)

The "number of units" may be larger, smaller, or equal to 1.

Then the price per cup (8 ounces) would be ...

  unit price = (price for 15 oz)/(15/8 cups) = ($2.79)(8/15)

  = $1.488 per cup

__

The price per ounce would be ...

  unit price = ($2.79)/(15 oz) = $0.186/oz

__

We assume that the unit of interest is probably 1 ounce, but it could be something else. Your grader may expect the value to be rounded to the nearest cent, $0.19 per ounce.

The unit price of shampoo is approximately $0.186 per ounce.

To find the unit price of shampoo, divide the cost of the bottle by the number of ounces it contains. In this case, the cost is $2.79 and the bottle is 15 ounces. So, the unit price can be calculated as $2.79 divided by 15 ounces, which gives us approximately $0.186 unit price per ounce.

Answer: 90 tarts

Step by Step: 150/5 = 30

30 multiplied times 3 = 90

Final answer:

Jake initially had 750 tarts, sold 450 of them, and had 150 tarts remaining after giving some to his friends.

Explanation:

Jake initially had a total number of tarts. He sold 3/5 of them and then gave 1/4 of the remainder to his friends. If he had 150 tarts left, we need to calculate the number he sold. Let's denote the total number of tarts as T. After selling 3/5 of T, Jake would have 2/5T left. Then, he gives away 1/4 of 2/5T, which means he's giving away 1/4 * 2/5T = 1/10T. So, he is left with 2/5T - 1/10T = 1/5T. We know that 1/5T equals 150, so T equals 150 * 5 = 750. Jake sold 3/5 of these, which is 3/5 * 750 = 450 tarts.

Answer:

$883.40

Step-by-step explanation:

Calculate the amount of money needed to pay after the discount.n

$1049 × 88% = $923.12

Calculate the amount of money needed to pay after the tax.

$923.12 × 104.5% = $883.3684210526

=$883.40(rounded off to nearest cents)

hope  this helps

To find the final price of the television on sale, calculate the discount amount, subtract it from the original price, and then add the sales tax amount.

To find the final price of the television, we first need to find the discount amount by multiplying the original price ($1,049) by the discount percentage (12%).

Discount amount = $1,049 × 0.12 = $125.88

Next, subtract the discount amount from the original price to get the sale price:

Sale price = $1,049 - $125.88 = $923.12

Finally, add the amount of sales tax to the sale price. To find the sales tax amount, multiply the sale price by the sales tax rate (4.5%):

Sales tax amount = $923.12 × 0.045 = $41.54

Final price = Sale price + Sales tax amount = $923.12 + $41.54 = $964.66

Step-by-step explanation:

Answer: x = 995

Step-by-step explanation:

In this equation our log doesn't have a base so it is given the default base of 10. This makes our equation really.

[tex]log_{10}(x+3) + log_{10}(2) = 3[/tex]

Now we put every equation as the exponent of our base 10 looks like this:

[tex]10^{log_{10} (x+3)} + 10^{log_{10} (2)} = 10^{3}[/tex]

Now we cancel out the log base 10 and the 10. We are left with:

(x+3) + (2) = 10^3

Lastly solve for x

x + 5 = 1000

x = 995

Answer:

See photo

Step-by-step explanation:

The line is in slope-intercept form which looks like y = mx + b.

"x" and "y" represent points on the line.

"m" is the slope (how steep the line is) and if the line goes up (+) or down (-).

"b" is the y-intercept, which is where the graph hits the y-axis.

Take information from the equation y=-2x+6. Use the slope and the y-intercept to graph to line.

m = -2  =  [tex]-\frac{2}{1}[/tex]   (Fraction form).

b = 6

Plot a point at the y-intercept on the y-axis

If the y-intercept is 6, so you plot the point at (0, 6). (The y-intercept occurs when x = 0).

Find another point

Count the number of rise and run from the y-intercept.

Remember the slope is [tex]\frac{rise}{run}[/tex]

Run is the number of squares moving right. Rise is the number of squares moving up (if positive) or down (if negative).

Since the slope is -2/1, move two squares down and one square to the right to find another point on the line.

Connect the points

You only need two points to make a line. If you want the line to be longer, you can extend it with a ruler.

Other formatting rules

Remember to add arrows at the ends of the x and y axis.

Also, add arrows to the ends of the the line that you graphed.

Most teachers ask you to label the line with the equation.

It takes about 14.55 years for quadruple your money

Solution:

Given that,

At 10 percent interest, how long does it take to quadruple your money

Rule of 144:

The Rule of 144 will tell you how long it will take an investment to quadruple

Here,

Rate of interest = 10 %

Therefore, number of years to quadruple your money is obtained by dividing 144 by 10

Rule of 144 Formula:

[tex]N = \frac{144}{R}[/tex]

Where:

N = Number of many years times.

144 = Is the constant variable.

R = Rate of interest.

[tex]\rightarrow N = \frac{144}{10} = 14.4[/tex]

Thus it takes about 14.4 years for quadruple your money.

Another method:

If initial amount is $ 1 and it if quadruples it should be $ 4

We have to find the number of years if rate of interest is 10 %

Let "n" be the number of years

Then we can say,

[tex]Amount = Principal(1+\frac{R}{100})^n[/tex]

[tex]4 = 1(1+\frac{10}{100})^n[/tex]

[tex]4 = 1(1+0.1)^n\\\\4= 1(1.1)^n\\\\4 = 1.1^n\\\\We\ know\ that,\\\\(1.1)^{14.55} = 1.1^n\\\\We\ know\ that\\\\If\ a^m = a^n\ then\ m = n\\\\Therefore,\\\\14.55 = n\\\\n = 14.55[/tex]

Thus Option D 14.55 years is correct
