Find the missing measure for a right circular cone given the following information. Find r if T.A. = 12pi and L.A. = 8pi

Answers

ARea of base = TA - LA = 4pi

pi r^2 = 4 pi where r is radius of base.

r^2 = 4

so r = 2 Answer

Answer:

r = 2 units

Step-by-step explanation:

Total area(T.A) of the circular cone is given by:

[tex]\text{T.A} =\pi r^2+ \pi r\sqrt{r^2+h^2}[/tex]

Lateral surface area(L.A) of the circular cone:

[tex]\text{L.A} = \pi r\sqrt{r^2+h^2}[/tex]

where

r is the radius and h is the height of the circular cone.

As per the statement:

[tex]T.A = 12 \pi[/tex] and [tex]L.A = 8 \pi[/tex]

then;

[tex]T.A -L.A = \pi r^2+ \pi r\sqrt{r^2+h^2}-\pi r\sqrt{r^2+h^2}[/tex]

⇒[tex]12 \pi -8 \pi = \pi r^2[/tex]

⇒[tex]4 \pi =\pi r^2[/tex]

Divide both sides by [tex]\pi[/tex] we have;

[tex]4 =r^2[/tex]

[tex]r^2 = 4[/tex]

⇒[tex]r= \pm\sqrt{4} =\pm 2[/tex]

r cannot be in negative

⇒[tex]r = 2[/tex] units

Therefore, radius of the circular cone is, r = 2 units

What does the property Additive Identity, Additive Inverse, Multiplicative Identity, and Multiplicative Inverse mean?

Answers

Additive identity is any number you can add plus zero. (So any number.)
Multiplicative Identity is any number multiplied by one.
Additive inverse is subtracting the positive number in an equation on both sides of the equal sign.
Here's an example since that was a bad explanation:
x+3=15
The next step is to do the inverse of adding three to both sides of the equal sign so you're subtracting three.
and multiplicative is pretty much the same besides instead of subtracting you're dividing. I hope that helped! :)

A state auto-inspection station has two inspection teams. team 1 is lenient and passes all automobiles of a recent vintage; team 2 rejects all autos on a ﬁrst inspection because their “headlights are not properly adjusted.” four unsuspecting drivers take their autos to the station for inspection on four different days and randomly select one of the two teams. a if all four cars are new and in excellent condition, what is the probability that three of the four will be rejected? b what is the probability that all four will pass?

Answers

The probability of passing and rejection is equally likely given that one of the teams are randomly selected for the inspection and that the drivers are unsuspecting.

Thus, P(passing) = 1/2
P(rejection) = 1/2

Part A:

The probability that three of the four will be rejected is given by

[tex]P(RRRP)=\ ^4C_3\times\left( \frac{1}{2} \right)^3\times\left( \frac{1}{2} \right) \\ \\ =4\times \frac{1}{8}\times \frac{1}{2} =\frac{1}{4}=25\%[/tex]

Part B:

The probability that all four will pass is given by

[tex]P(PPPP)=\ ^4C_4\times\left( \frac{1}{2} \right)^4\\ \\ =1\times \frac{1}{16} =\frac{1}{16}=6.25\%[/tex]

Work out the total amount Adam earned last week

Answers

Okay, so we know that Adam earns £200, plus 10% of (42*8) and 15% of (15*14)
To work out the payment for the magazines, you multiply 42 and 8, which gives 366 and find 10% of that, which is £36.60
To work out the payment for the books, you multiply 14 by 15, which gives 210 and find 15% of that, which is £31.50
Then add all the amounts together
£200+ £36.60+ £31.50= £268.10

За 7 кг груш заплатили 525 руб. Сколько рублей следует заплатить за 4,6 кг груш?

Answers

Answer: 345 руб.

Step-by-step explanation:

525 : 7 = 75 (руб.) - стоимость 1 кг груш.

4,6 * 75 = 345 (руб.) - следует заплатить за 4,6 кг груш.

Final answer:

To find out how much to pay for 4.6 kg of pears, calculate the price per kilogram from the given 7 kg cost (525 rubles) and multiply by 4.6 kg, resulting in a price of 345 rubles for 4.6 kg.

Explanation:

The cost for 7 kg of pears is 525 rubles. To determine how much one should pay for 4.6 kg of pears, we use a simple proportion based on the principle that the price per kilogram remains constant.

First, we find the price per kilogram by dividing the total cost by the weight:

Price per kilogram = Total cost / Total weight in kgPrice per kilogram = 525 rubles / 7 kg = 75 rubles/kg

Now, we multiply the price per kilogram by the desired weight to get the total cost for 4.6 kg:

Total cost for 4.6 kg = Price per kilogram * Weight of the pearsTotal cost for 4.6 kg = 75 rubles/kg * 4.6 kg = 345 rubles

Therefore, one would need to pay 345 rubles for 4.6 kg of pears.

What are the real and imaginary parts of the complex number? −6−i Enter your answers in the boxes. The real part: The imaginary part:

Answers

Answer:

Real part = -6 and imaginary part = -i

Step-by-step explanation:

A complex number can be written as a + bi,

where both a and b are real numbers,

While, i is an imaginary number ( equals to √-1, because √-1 does not defined as a real number ),

The product of a real number and imaginary number is imaginary number,

∴ bi is called imaginary part of a + bi

Also, a is real number ⇒ a is real part of a + bi

Here, the given complex number,

-6-i

By comparing,

Imaginary part = -i, real part = -6.

We want to see the real and imaginary parts of a given complex number.

The real part is: -6

The imaginary part is: -1

A general complex number is written as:

z = a + b*i

Where a is the real part and b is the imaginary part.

In this case, we have the number:

z = -6 - i

We can rewrite this as:

z = -6 + (-1)*i

Then the real part is the number that is alone, in this case, -6.

The imaginary part is the coefficient that multiplies the "i", which is -1.

On average nick walks 18000 steps every day he walks 1 mile every 3500 steps work out an estimate for the average distance in miles that nick walks in one year

Answers

First, we need to know how many miles he walks in one day. To do this we must do the following:
[tex] \frac{18000}{3500} =5.14miles[/tex]

Now that we know he walks 5.14 miles per-day we would multiply that by the number of days in a year, or 365.
[tex]5.14 *365=1846[/tex]

So Nick walks about 1,846 miles in one year.

Final answer:

To find the average distance Nick walks in a year, divide 18,000 steps by 3,500 steps per mile to get 5.14 miles per day, and then multiply by 365 days to estimate around 1,876.1 miles annually.

Explanation:

To estimate the average distance in miles that Nick walks in one year, we need to start with the information that Nick walks 18,000 steps every day and that he walks 1 mile every 3,500 steps. First, we need to calculate the number of miles Nick walks each day by dividing the total daily steps by the number of steps per mile:

Daily miles = 18,000 steps/day ÷ 3,500 steps/mile = 5.14 miles/day (rounded to two decimal places)
Next, we will calculate Nick's annual walking distance by multiplying the miles per day by the number of days in a year (365):

Annual distance = 5.14 miles/day × 365 days/year = 1,876.1 miles/year (rounded to one decimal place)

Therefore, we can estimate that Nick walks approximately 1,876.1 miles in one year.

You have purchased a 42 inch television with an aspect ratio of 16:9. You want to watch a movie which has an aspect ratio of 1.85:1. Find the following measurements & show all work: 1. Height of the television screen 2. Width of the television screen 3. Height of the black bars at the top and bottom of the screen. 4. Percent of the area of the television screen that is covered by the image.

Answers

(16x)2+(9x)2=422337x2=422x2=422337x=42337−−−√so dimensions are16×42377−−−√and9×42337−−−√

Final answer:

The TV's width and height are approximately 36.61 inches and 20.55 inches respectively. The black bar's height is approximately 1.29 inches each. The movie covers almost 87.4% of the TV's screen area.

Explanation:

This question involves the use of ratios and some geometry. Your TV's aspect ratio of 16:9 essentially means the width is 16 parts and the height is 9 parts. And, the total diagonal is given 42 inches.

1. Using Pythagorean theorem a² + b² = c² where c is the hypotenuse (diagonal), the width and height of the TV can be found: height(h)= ratio_height * √(c²/(ratio_width² + ratio_height²)) = 9 * √(42²/(16² + 9²)) ≈ 20.55 inches.

2. Similarly for width(w): w= ratio_width * √(c²/(ratio_width² + ratio_height²)) ≈ 36.61 inches.

3. The movie's aspect ratio is 1.85:1. The height of the black bars can be calculated using ratio of the heights of the movie and the TV: black bar height= (h - w/1.85) / 2 ≈ 1.29 inches. This height is subtracted from the TV's height because the movie with ratio 1.85:1 is wider than 16:9 TV.

4. The percentage coverage is given by (w * (h - 2* black bar height)) / (w * h) ≈ 0.874 or 87.4%

Arthro is making 5 pounds of snack mix from raisins and almonds. the raisins cost $3 per pound, and the almonds cost $8 per pound. he wants the cost of the snack mix to be $6.50 per pound. how many pounds of each item should he use?

Answers

This is a system of equations problem.
Let r = pounds of raisins
and a = pounds of almonds
We know that r + a = 5. this is our first equation
The second one is more tricky, 3r + 8a = 6.5*5
Now solve:
r = 5 - a
3(5 - a) + 8a = 6.5*5
15 - 3a + 8a = 32.5
5a = 17.5
a = 3.5
r = 5 - 3.5
r = 1.5
He should use 3.5 pounds of almonds and 1.5 pound of raisins

A person is strolling along a moving walkway at a constant velocity of +1.00 m/s with respect to the walkway, which moves at a constant velocity of +0.50 m/s with respect to the ground. an observer on the ground is walking at a constant velocity of -0.2 m/s. what is the velocity of the person on the walkway with respect to the observer on the ground?

Answers

Refer to the diagram shown below.

The velocity of the person on the walkway relative to the ground is the velocity of the walkway (relative to the ground) plus the velocity of the person relative to the walkway.
It is
1.0 + 0.5 = 1.5 m/s

The person on the ground moves at - 0.2 m/s, which is in the opposite direction to that of the walkway and the person on the walkway.
Therefore the velocity of the person on the walkway relative to the person on the ground is
105 - (-0.2) = 1.7 m/s

Answer: 1.7 m/s
