It takes Jill 2 hours to run 14.5 miles, At this rate, how far could she run in 3 hours? Btw, I am giving a lot of points if you get it correct!
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:
A bag contains 9 red marbles,5 green marbles, and 6 purple marbles.
What are the odds of picking a red marble?
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%.

How many times can 1/6 go into 4
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.

Step-by-step explanation:
Eduardo earns a base salary of $30,000 per year and earns $1,875 per car he sells. Which equation can be used to find the number of cars, c, that Eduardo sold in a year he made 46,875 ?
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.

Paula leaned a 10 ft ladder against a building as shown below. if Paula wants the top of the ladder to reac
h exactly 5 feet up in the building, what is x the distance between the building and the base of the ladder, in feet?
The distance between the building and the base of the ladder is 5√3 feet.
Step-by-step explanation:
Consider a right angle triangle,
Hypotenuse = Paula leaned a 10 ft ladder against a building.Height = the top of the ladder is exactly 5 feet up in the building.Base = 'x' ft, distance between the building and the base of the ladder.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.

Second time asking plz help. Linear or exponential. plz help me :(
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.

Solve (x + 5 < 4) ∩ (x - 3 > -6)
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
Can I get help please ?
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

Joyce is thinking of a 3 - digit number. Her number has the digits 8,4, and 6. To the nearest hundred, it rounds to 600. What is the number?
Answer:
684 :)
Step-by-step explanation:
Joyce's number is 648.
To determine Joyce's number, we need to use the information that it has the digits 8, 4, and 6, and it rounds to 600 to the nearest hundred. Here's how we can approach this:
The number must round to 600, so it must be closer to 600 than to 500 or 700. This means it must be in the range 550 to 649.We need to form numbers using the digits 8, 4, and 6: 486, 468, 846, 864, 684, and 648.Comparing these numbers, only 648 falls within the range of 550 to 649.Therefore, Joyce's number is 648.

560m
314m
340m
524m
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.
