The time they would both meet at the starting point is 140 minutes (third option).
When would they meet at the starting point?The time they would both meet at the starting point will be a common multiple of the time it takes each of them to complete a lap.
A multiple of a number is the product of an integer and that number. A common multiple is a multiple that is common to two or more numbers.
Multiple of 20 = 20, 40, 60, 80, 100, 120, 140

(HELP) The town of Miami is mapped on a coordinate
grid with the origin being at City Hall. Jordan's house
is located at the point (-5, 7) and Ca'Miyah's house is
located at (-2, 3). To the nearest tenth, How far is it
from Jordan's house to Ca'Miyah's house?
(51)
Answer: 5.2
Step-by-step explanation:
If we put both points on a grid, Jordan's house would be 4 points above and 3 points to the left of Ca'Miyah's. We can plug these two amounts into the pythagorean theorem to find the distance between the houses: 4^2 + 3^2 = x^2. If we solve this equation, we get 5.196, which rounds to 5.2.

The increase in the money supply that causes prices to rise and leads to inflation, loses purchasing power.
What is inflation?
Inflation refers to the persistent rise in the general prices of commodities in the economy over a period of time. If the prices of goods and services increase in an economy without an increase in income of people, it reduces the purchasing power of individuals.
This follows the law of demand which states that; the higher the price, the lower the quantity demanded; the lower the price, the higher the quantity demanded.

2x + 3y = 1200, 3x + 2y = 1300. what is the value of 5x + 5y using substitution method
The value of 5x + 5y is 2500 by substitution method.
According to the given question.
We have two equations
2x + 3y = 1200
3x + 2y = 1300
Since, we have to find the value of 5x + 5y by substitution method.
From equation 2x + 3y = 1200
2x = 1200 - 3y
⇒ x = [1200 -3y]/2
Substitute the value of x in 3x + 2y = 1300.
⇒ 3[1200 - 3y]/2 + 2y = 1300
⇒ 3[600 -3y/2] + 2y = 1300
⇒ 1800 - 9y/2 + 2y = 1300
⇒ 1800 + (4y - 9y)/2 = 1300
⇒ (4y - 9y)/2 = -500
⇒ -5y = -1000
⇒ y = 200
So,
x = [1200 - 600]/2 = 600/2 = 300
Thereofore, the value of 5x + 5y by substitution method is given by
5(300) + 5(200)
= 1500 + 1000
= 2500
Hence, the value of 5x + 5y is 2500 by substitution method.

The least amount of hours of footage the observers need to review to see the Cape Sable seaside sparrow and the Florida leafwing butterfly in the area at the same time is B. 36 hours.
What is the least common multiple?The least common multiple (LCM) is the smallest multiple of two or more numbers.
The LCM of 9 and 4 is 36 (4 x 9).
Data and Calculations:The total number of hours of filming and recording by the stationary camera is 96.
The regularity of observing the Cape Sable Seaside Sparrows = every 4 hours
The regularity of observing the Florida Leafwing Butterfly = every 9 hours
Using their LCM as 36,
The Cape Sable Seaside Sparrows will be observed 9 times when they meet the Florida Leafwing Butterfly at its 4th observation.
Thus, the least amount of hours of footage the observers need to review to see the Cape Sable seaside sparrow and the Florida leafwing butterfly in the area at the same time is B. 36 hours.

The probability of either A or B occurring will be 0.8.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Being connected in a way that one excludes or prevents the other events from happening also: completely at odds despite the fact that their viewpoints did not conflict.
Suppose that A and B are mutually exclusive events for which P(A) = 0.3 and P(B) = 0.5.
Then the probability of either A or B occurring will be
P(AUB) = P(A) + P(B)
P(AUB) = 0.3 + 0.5
P(AUB) = 0.8

11. PARKS The Hillsborough State Park in

fee of $4 plus a camping fee of $20 per
night. This can be represented by the
function f(x)
20x +4, where f(x) is the total
cost and x is the number of nights spent
camping. What is the value of f(5), which is
the cost of 5 nights of camping? (Lesson 2-1)
A. 80
B. 100
C. 104
D. 120
Answer:
f(5) = 104
Step-by-step explanation:
To find the value of f(5), we have to plug in 5 into our equation f(x) = 20x + 4.
f(5) = 20(5) + 4
Following our order of operations, we multiply first, then add to get our answer.
f(5) = 20(5) + 4
f(5) = 100 + 4
f(5) = 104
The cost of 5 nights of camping is $104.

Answer:
Domain: [tex]x > -5[/tex] or [tex](-5,\infty)[/tex]
Range: [tex]y\geq -3[/tex] or [tex][-3,\infty)[/tex]
Step-by-step explanation:
The domain is essentially the set of x-values in a given graph. In this graph. we see that the lowest x-value is an unfilled dot when x=-5. The unfilled dot means that the function [tex]f(x)[/tex] doesn't include -5. We then see that the x-value goes to positive infinity. This means that [tex]x[/tex] must be greater than -5. It is not greater or equal to -5 because the dot is not filled.
Therefore, we have that [tex]x > -5[/tex]. To convert to interval notation we can take the lower value (-5) and put it on the left side and put the higher value ([tex]\infty[/tex]) and put it on the right side. Since the graph doesn't include -5, we can put parentheses around both values to get [tex](-5,\infty)[/tex].
Note: We always put parentheses around both [tex]\infty[/tex] and [tex]-\infty[/tex].
The range is basically the same as the domain but with the y-value. We can see that the lowest y-value is y=-3. This includes -3 since the line fills the point in. Then we see that the highest y-value is once again positive infinity. This means that [tex]y\geq-3[/tex].
Now when we convert to interval notation, we have -3 and [tex]\infty[/tex]. This time since y=-3 is included in the function, we put a hard bracket around -3. Thus, we get [tex][-3,\infty)[/tex].

What Is the Square Root of 175? The square root of 175 is defined as the value obtained on the multiplication of an integer by itself which will give the final product as 175. As there is no such integer which on multiplication with itself will give 175 exactly, the square root of 175 is not a whole number.

now when we simplify the inequality 2x on the both sides will be eliminated and we will be left with:

To solve, simplify the first part of the inequality by solving for x.
-x - 8 ≤ -15
Add 8 to both sides
-x - 8 + 8 ≤ -15 + 8
-x ≤ -7
Divide both sides by -1
Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.
-x/-1 ≥ -7/-1
x ≥ 7
Next, simplify the second part of the inequality by solving for x
-18 ≤ -x - 8
Rewrite as
-x - 8 ≥ -18
Add 8 to both side
-x - 8 + 8 ≥ -18 + 8
-x ≥ -10

[tex]f(t)=a\times(1/2)^{\frac{t}{h}}[/tex]
t = time passeda = y-intercepth = half lifeSolving the QuestionWe're given:
h = 28 million yearsa = 184 grams (this is the initial mass, after 0 time has passed)For most questions like this, we would have to plug these values into the equation mentioned above. However, this question asks for the time elapsed after 3 half-lives.
This can be calculated simply by multiplying the given half-life by 3:
