Answer:

201.06

Step-by-step explanation:

This is because the formula of the area of a circle is A=(pi)(r) squared

Since the radius if half of the diameter, the radius would then be 8.

8 squared, or 8 x 8 = 64.

64 times pi (64 x 3.14159)= 201.06

Therefore the sum of the series is -16.

Answer: There are 43 white marbles.

Step-by-step explanation:

t = total number of marbles = 54

w = white marbles = 4b - 1

b = blue marbles

54 = b + (4b - 1)

b + 4b = 5b

54 = 5b - 1

+1

55 = 5b

/5

11 = b

There are 11 blue marbles.

4(11) - 1

44 - 1 = 43

43 + 11 = 54, therefore our solutions are correct.

Answer:

43

Step-by-step explanation:

W = 4B - 1

W + B = 54

4B - 1 + B = 54

5B = 55

B = 11

W = 4(11) - 1

W = 43

here's your reminder to fix your posture (you know you're slouching, that'll hurt your back when you're old lol) and go get some water! hydration is best because your body uses it to regulate body temperature, keep joints lubricated, prevent infections, deliver nutrients to cells, and keep organs functioning properly. being well-hydrated also improves sleep quality, cognition, and mood! also, if you don't drink water for 3-21 days (depends on age and body and stuff) you'll die. so there's that too.

The satellite's speed is approximately 45,216 kilometers per hour.

Calculating the Satellite's Speed

To find the satellite's speed in kilometers per hour, we can follow these steps:

1. Calculate the total distance traveled in one orbit:

The satellite's orbital distance is the circumference of its circular orbit around the Earth.

Circumference = 2 * π * radius

where:

π (pi) is a mathematical constant approximately equal to 3.14159

radius = distance from the satellite to the Earth's center = 6400 km + 2000 km = 8400 km

2. Calculate the orbital period in seconds:

We know the orbital period is 12 hours, but we need it in seconds for our calculations.

Convert hours to seconds: 12 hours * 60 minutes/hour * 60 seconds/minute = 43,200 seconds

3. Calculate the speed:

Speed = distance / time

Speed = total distance / orbital period

Speed = (2 * π * radius) / orbital period

Speed = (2 * 3.14159 * 8400 km) / 43,200 seconds

Speed ≈ 12.56 km/s

4. Convert speed to kilometers per hour:

Speed = 12.56 km/s * 3600 seconds/hour = 45,216 km/hr

Therefore, the satellite's speed is approximately 45,216 kilometers per hour.


The probable question can be: A satellite has recently been placed in a nearby circular orbit 2000 kilometers above the earth surface. Given that the radius of the earth is approximately 6400 kilometers and that the satellite completes its orbit in 12 hours, CALCULATE THE SPEED OF THE SATELLITE IN KILOMETERS PER HOUR.

What two numbers multiply to 15 and add to 8

5*3 = 15

5+3 = 8

(x+5) (x+3)

Answer:

x = 25

Step-by-step explanation:

Given

0.2(x + 5) + 1 = 7 ( subtract 1 from both sides )

0.2(x + 5) = 6 ( divide both sides by 0.2 )

x + 5 = 30 ( subtract 5 from both sides )

x = 25

Answer:

50.29

Step-by-step explanation:

(25 1/7)/(22/7) = diameter

8 = diameter -->

4 = radius

4^2 pi = area

16pi=area

16*22/7 = area

352/7 = area

50.29 is (approx.) area

Recall that the tangent of an angle is equal to the ratio of the opposite over adjacent sides

tan(angle) = opposite/adjacent

For reference angle Y, the opposite side is XZ = 6 and the adjacent side is XY = 7, so,

tan(Y) = XZ/XY = 6/7

For tan(Z), things will swap. The opposite side is now XY = 7 and the adjacent side is now XZ = 6

tan(Z) = XY/XZ = 7/6

We do not use the hypotenuse sqrt(85) at all in this problem because the tangent ratio does not involve the hypotenuse.

To represent the total cost of admission for the number of visits in a season, an arithmetic sequence can be created with a common difference of $45. The cost of admission for the first visit is $45, and the sequence can be extended to five terms. To determine when a season pass becomes the better deal, compare the total cost of admission with the cost of a season pass. A person would have to visit the park at least 3 times for a season pass to be the better deal.

a. To represent the total cost of admission for the number of visits in a season, we can create an arithmetic sequence. The common difference will be the cost of admission each time a person visits the park, which is $45. The first term can be the cost of admission for the first visit, which is also $45. So, the arithmetic sequence will be:

b. To find out how many times a person has to visit the park for a season pass to be the better deal, we need to compare the total cost of admission for the number of visits with the cost of a season pass. In this case, the season pass costs $112 per person, so we need to find the number of visits that would equal or exceed the cost of a season pass. From the arithmetic sequence we created in part a, we can see that a person would have to visit the park at least 3 times for the total cost of admission to equal or exceed the cost of a season pass. Therefore, a person would have to visit the park at least 3 times for a season pass to be the better deal.

To find the menu price of an item after a total charge of $16.7 with a 7.6% local sales tax, calculate the total sales tax amount and then deduct it from the total cost to obtain the menu price of $15.43.

Explanation:

To find the menu price of the item after being charged $16.7 in total for a meal with a 7.6% local sales tax:

Calculate the sales tax amount: 7.6% of $16.7 = $1.27

Subtract the sales tax from the total cost: $16.7 - $1.27 = $15.43

Therefore, the menu price of the item was $15.43. Make sure to round off correctly based on the question requirements.

Answer: The estimated 15% tip would be $4.50.

Step-by-step explanation: Basically, first you will need to round the bill amount, $31.51 to the nearest ten dollars. 31.51 rounded to the nearest ten dollars is $30. Next, you will need to find the estimated tip amount. To do this multiply $30 by the tip 15%. Before you can find the tip amount, you will need to covert 15% to a decimal. To convert 15% to a decimal, divide 15 by 100 to get 0.15. Now, you can multiply 30 by 0.15 to get 4.50. So, $4.50 would be the tip if $31.51 was rounded to the nearest ten dollars.

Answer:

The volume of the cone with the same radius and height as the given cylinder is approximately [tex]\(459.325 \, \text{cm}^3\)[/tex].

Explanation:

To find the volume of a cone with the same radius and height as the given cylinder, we'll use the formula for the volume of a cone:

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

Given that the cylinder has a volume of 1884 cm³, and the radius [tex](\(r\))[/tex] and height [tex](\(h\))[/tex] of the cone are the same as the cylinder, we can first find the radius and height of the cylinder.

The volume of the cylinder is given by:

[tex]\[ V_{\text{cylinder}} = \pi r^2 h \][/tex]

Given [tex]\(V_{\text{cylinder}} = 1884 \, \text{cm}^3\)[/tex], we can solve for [tex]\(r^2 h\)[/tex], the product of the square of the radius and the height:

[tex]\[ r^2 h = \frac{1884}{\pi} \][/tex]

Now, we need to find the radius and height of the cylinder. Since we're told that the cone has the same radius and height as the cylinder, we can use these values for the cone as well.

[tex]\[ r^2 h = \frac{1884}{\pi} \][/tex]

Given that [tex]\( r = h \)[/tex], we can substitute [tex]\(r\)[/tex] for [tex]\(h\)[/tex] to get:

[tex]\[ r^3 = \frac{1884}{\pi} \][/tex]

[tex]\[ r = \sqrt[3]{\frac{1884}{\pi}} \][/tex]

Now that we have the value of [tex]\(r\)[/tex], we can find the volume of the cone using the formula for the volume of a cone:

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

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \sqrt[3]{\frac{1884}{\pi}} \right)^2 \left( \sqrt[3]{\frac{1884}{\pi}} \right) \][/tex]

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{1884}{\pi} \right)^{2/3} \left( \frac{1884}{\pi} \right)^{1/3} \][/tex]

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{1884^2 \cdot 1884}{\pi^2} \right)^{1/3} \][/tex]

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{1884^3}{\pi^2} \right)^{1/3} \][/tex]

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi \left( \frac{671161856}{9.869604401} \right)^{1/3} \][/tex]

[tex]\[ V_{\text{cone}} \approx \frac{1}{3} \pi \left( 67968372.82 \right)^{1/3} \][/tex]

[tex]\[ V_{\text{cone}} \approx \frac{1}{3} \pi \cdot 438.327 \][/tex]

[tex]\[ V_{\text{cone}} \approx 459.325 \, \text{cm}^3 \][/tex]

Answer:

Lin = 48 seconds  

Diego = 30 seconds  

Step-by-step explanation:

Hi, to answer this question we have to divide the total ounces of drink by the amount that each one drank per second, for each case.

Mathematically speaking:

Lin = 12 ounces / (1/4) ounces/second = 12/ (1/4) = 48 seconds  

Diego = 20 ounces / (2/3) ounces/second = 20/ (2/3) = 30 seconds  

Feel free to ask for more if needed or if you did not understand something.

Lin = 48 seconds  

Diego = 30 seconds  

Lin = 12 ounces ÷ (1/4) ounces/second = 12 ÷ (1/4) = 48 seconds  

Diego = 20 ounces ÷ (2/3) ounces/second = 20 ÷  (2/3) = 30 seconds
