Step-by-step explanation: 361 1/2

Step-by-step explanation:

V = 4/3 π r³

V = 4/3 π (5 m)³

V = 524 m³

Final answer:

The volume of a sphere with a radius of 5 meters rounded to the nearest whole number is 524 cubic meters, calculated using the formula V = (4/3)πr³.

Explanation:

The question is asking for the volume of a sphere with a radius of 5 meters. To find the volume of a sphere, we use the formula V = (4/3)πr³, where V is the volume and r is the radius of the sphere. In this case, the radius r is given as 5 meters.

Plugging in the values, we get:
V = (4/3)π(5³) = (4/3)π(125) = 523.6 cubic meters.
When we round to the nearest whole number, we get 524 cubic meters.

Therefore, the correct answer from the options provided is 524m³.

Answer:

4 and 13

Step-by-step explanation:

(a)

To evaluate f(3) substitute x = 3 into f(x), that is

f(3) = 3 + 1 = 4

(b)

To evaluate gf(3) substitute f(3) = 4 into g(x), that is

g(4) = 4² - 3 = 16 - 3 = 13

The distance between the building and the base of the ladder is 5√3 feet.

Step-by-step explanation:

Consider a right angle triangle,

From the Pythagorean theorem,

Base, x = [tex]\sqrt{hypotenuse^{2}-height^{2} }[/tex]

⇒ x = [tex]\sqrt{10^{2} -5^{2} }[/tex]

⇒ x = [tex]\sqrt{100-25}[/tex]

⇒ x = [tex]\sqrt{75}[/tex]

⇒ x = 5√3

The distance between the building and the base of the ladder is 5√3 feet.

Answer:

Below.

Step-by-step explanation:

The difference of the f(x) values divided by the difference in the corresponding x values.

That would be (f(2) - f(-2)) / (2 - (-2))

d) 4 × 1.98 = $7.92

Answer:

Exponential

Step-by-step explanation:

The change isn't constant for the volume, so it must be exponential.

Using quadratic regression, the equation is:

[tex]y=\frac{19}{63}x^{2}-\frac{968}{105}x+\frac{3312}{35}[/tex]

Answer:

I agree it's exponential, but it's so much simpler than you guys make it out to be. An easy way to check is to measure the distance in the x and y values to see if they change at a constant rate.

for instance; 1) abs(0-3) =3  95-69= 26  

2) abs(3-6) = 3     59-50= 19 ...

It's easier, faster, and less to memorize

Answer:

x>3

Step-by-step explanation:

add 2x to both sides and subtract 10 from both sides. Then divide by 6.

Answer:

x>3

Step-by-step explanation:

1- subtract 10 from both sides so (4x+10-10>28-2x-10)

2- Simplify (4x>-2x+18)

3- Add 2x to both sides (4x+2x>-2x+18+2x)

4- Simplify (6x>18)

5- Divide both side by 6 (6x/6>18/6)

6 Simplify which gives you (x>3)

Answer:

21.75

Step-by-step explanation:

To find how long she can run in a single mile, divide 14.5 by 2, giving you 7.25. If she runs three of those, (3 times 7.25), she runs 21.75 miles.

Answer: 21.75miles

Step-by-step explanation:

Let the number of miles for 3 hours be represented as x

If 2 hours = 14.5 miles

Then, 3 hours = x

We Cross multiply

2x = 14.5 × 3

2x = 43.5

Divide both sides by 2

x = 43.5/2

x = 21.75

In 3 hours, Jill will be able to run 21.75miles. I hope this helps.

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

1) let’s take the original number as “x”

So

3x=28-0.5x

Lol don’t worry I’ll show you how I got that

So it says 3 times a number. That tells me my number, X is multiplied by 3 so I have

3x so far

Next it says “is equal to”, this tells me my number 3x is equal to something so I have this now:

3x=

After that it says “half of a number” so I know I will have 0.5x subtracted from 28. Since it says subtracted from 28 that means my number will be subtracted from 28, not the other way around so

3x=28-0.5X

Now I can solve this by bringing “-0.5” to the left.

3x+0.5x=28

3.5x=28

Divide both sides by 3.5 and

X=8

Step 1:  Make common denominators

What is the LCM of 21 and 7:  7

So, we need to convert both fractions into a 21 denominator.

15/21 * 1/1 = 15/21

5/7 * 3/3 = 15/21

Step 2:  Subtract the numbers

15/21 - 5/7 is same as 15/21 - 15/21

15/21 - 15/21

Step-by-step explanation:

Answer:

The equation is, A =30,000 + 1875n.

He sold 9 cars the year he made that amount of money.

Step-by-step explanation:

Before calculating, let's assign letters to certain variables:-

✓ let "A" be used to represent the total amount earned after adding his base salary to the amount he earned as commission per car he sells.

✓ "P" will be used to represent his base salary (a constant = 30,000)

✓ "n" will represent the number of cars sold within a given year.

✓ "B" will be used to represent his commission per car he sells.

Fixing them into a formula, we have:

A = P + n(B)

Since "P" and "B" are constants of 30000 and 1875 respectively, we substitute the letters for their actual amount in the formula:-

A = 30,000 + n(1875)

A = 30,000 + 1875n +This is now the equation that can be used to calculate the number of cars he sold in the year he earned 46,875).

So, since "A" is now $46,875, we substitute accordingly to find the number of cars he sold in the year he earned such amount.

46,875 = 30,000 + 1875b

1875n = 46,875 - 30,000

1875n = 16875

n = 16875/1875

n = 9 cars

Therefore the equation to be used to determine how many cars he sold when he earned $46,875 is:

A = 30,000 + 1875n

He sold 9 cars the year he earned $46,875.

Answer:

3/4

Step-by-step explanation:

2/3= 0.6

1/8= 0.125

3/4= 0.75

I convert the fractions into decimals the decimal with the highest number in the tenths place is the biggest

Hope This Helps!

Answer:

3/4

Step-by-step explanation:

if you convert them all to have the same denominator you find that 3/4 has the biggest numerator.

2/3 = 16/24

1/8 = 3/24

3/4 = 18/24 ← has the greatest numerator so it's the greatest

Answer:

Slope is -5

Step-by-step explanation:

The slope is the number attached to the x.

In this problem:  y = -5x - 1, the slope is -5 because it is the number attached to the x

Example:  y = -23/5x + 6

In this case, the slope is -23/5 because it is the number attached to the x.

Answer:  Slope is -5

The odds or probability of picking a red marble from a bag that contains 9 red marbles, 5 green marbles, and 6 purple marbles is 0.45 or 45%.

Probability refers to the chance, likelihood, or odds that an event occurs out of many possible events.

Probability is a value that ranges from 0 to 1, depending on the level of certainty.

The number of red marbles in the bag = 9

The number of green marbles in the bag = 5

The number of purple marbles in the bag = 6

The total number of marbles in the bag = 20 (9 + 5 + 6)

The probability of choosing or picking a red marble = 9/20 = 0.45 or 45%.

Answer: 883 people

Step-by-step explanation: If the bleachers can hold 149,227 pounds and each person weighs 169 pounds, then you would do 149,227 divided by 169 to get 883.

149,227 ÷ 169 = 883

Answer:

883 people

Step-by-step explanation:

This is a division problem.

(149,227 lb)/(169 lb) = 883

Answer: 883 people.

Answer:

∅ i.e empty

Step-by-step explanation:

(x + 5 < 4) ∩ (x - 3 > -6)

Let A represent the set (x + 5 < 4)

Let B represent the set (x - 3 > -6)

For set A:

x + 5 < 4

subtract 5 from both side

x < 4 —5

x < —9

Possible values of x are - 10, - 11, - 12,...

A = {- 10, - 11, - 12,...}

For set B:

x - 3 > -6

Add 3 to both side

x > -6 + 3

x > - 3

Possible values of x are - 2, - 1, 0,...

B = {- 2, - 1, 0,...}

A= {- 10, - 11, - 12,...}

A ∩ B = ∅ i.e empty

Therefore, (x + 5 < 4) ∩ (x - 3 > -6) is ∅ i.e empty

Final answer:

To determine how many times 1/6 can be contained in 4, we multiply 4 by the reciprocal of 1/6, which is 6. The answer is 24.

Explanation:

To find out how many times 1/6 can go into 4, we need to perform a division operation. We are essentially asking how many sixths are there in 4 wholes. This can be written as a division expression:

4 ÷ (1/6)

To divide by a fraction, you multiply by its reciprocal. For the fraction 1/6, the reciprocal is 6, so you multiply 4 by 6 to find the answer:

4 × 6 = 24

Therefore, 1/6 can go into 4 a total of 24 times.
