The visitor should run approximately 10.588 miles before swimming to minimize the time it takes to reach the island.
Here, we have,
To minimize the time it takes to reach the island, the visitor should run until the point where the time spent running is equal to the time spent swimming.
At this point, the total time taken to reach the island will be minimized.
Let's assume the distance the visitor runs is x miles.
Then the distance the visitor swims is (15 - x) miles.
Time spent running = Distance / Running rate
Time spent swimming = Distance / Swimming rate
Time spent running = x / 6
Time spent swimming = (15 - x) / 2.5
Now, we want to find the value of x that makes the time spent running equal to the time spent swimming:
x / 6 = (15 - x) / 2.5
To solve for x, cross-multiply:
2.5x = 6 * (15 - x)
2.5x = 90 - 6x
Add 6x to both sides:
2.5x + 6x = 90
8.5x = 90
Now, divide by 8.5:
x = 90 / 8.5
x ≈ 10.588
Now, the visitor should run approximately 10.588 miles before swimming to minimize the time it takes to reach the island.

Step-by-step explanation:
Angle PQS is found by 180-80=100
180- 100-30=50
Answer:
50 degrees
Step-by-step explanation:
<PQS +<RQS = 180°(sum of angles in a straight line)
#+80=180
#=180-80
#=100°
30° + x + # = 180°(sum of angles in a Δ)
30+x+100=180
x+130=180
x=180-130
x=50°

2. cube: V = s³; A = 6s². prism: V = lwh; A = 2(lw +h(l+w))
3. 400 cm²
Step-by-step explanation:
1, 2. Answers shown above. The formulas are from your list of formulas.
__
3. Cube surface area is ...
A = 6(20 cm)² = 2400 cm²
Prism surface area is ...
A = 2((40 cm)(20 cm) +(10 cm)(40 cm +20 cm))
A = 2(800 cm² +10(60) cm²) = 2(1400 cm²) = 2800 cm²
The difference in areas is ...
2800 cm² -2400 cm² = 400 cm² . . . . difference in surface area

Answer:
area of square = 100
area of circle = 15.7
the area of the shaded = im not really sure but im thinking its 50
Step-by-step explanation:
so u see the line in the middle it say 10 cm and the square is equal on all sides so it would be 10cm for the lenth and with so it would be 10 times 10 witch is 100 and u would use the 10 for the circle aswell witch u would use 3.14 times 10 divided by 2 to get the area of the circle
Answer:
The Area of the square is 100cm^2
The Area of the Circle is 78.54cm^2
The Area of the Yellow is 21.46cm^2

What is the Surface Area of this figure?
Answer:
[tex]174 cm^{2}[/tex]
Step-by-step explanation:
There are two triangles and two rectangles in the figure.
To find the area of the triangles:
6 x 9 = [tex]54cm^{2}[/tex]
To find the area of the rectangles:
9 x 8 = [tex]72cm^{2}[/tex]
6 x 8 = [tex]48cm^{2}[/tex]
Add all of this together for your answer:
54 + 72 + 48 = [tex]174cm^{2}[/tex]

Irma and Kate have summer jobs selling newspaper subscriptions door-to-door, but their
compensation plans are different. Irma earns a base wage of $15 per hour, as well as $1 for
every subscription that she sells. Kate gets $2 per subscription sold, in addition to a base
wage of $6 per hour. If they each sell a certain number of subscriptions in an hour, they will
end up earning the same amount. How many subscriptions would that be? How much would
each one earn?
If Irma and Kate sell

Select all expressions equivalent to 6x- - 24.
Answer:
the answer should/could be 6(x-4) & 3(2x-8)
Answer:
6(x - 4) & 3(2x - 8) is the answer
Step-by-step explanation:
6(x - 4) = 6x - 24
2(3x - 24) = 6x - 48
3(2x - 8) = 6x - 24
3(3x - 21) = 9x - 63

In the figure below, $AB=75,$ $AC=70,$ and $BY=60$. Compute $CX$.
Compute the area A of ∆ABC.
• Take AB to be the base and CX (which is an altitude of ∆ABC) to be the height. Then the area is
A = 1/2 • AB • CX = 1/2 • 75 • CX
• Now take AC to be the base and BY (also an altitude) to be the height. Then
A = 1/2 • AC • BY = 1/2 • 70 • 60 = 2100
The areas must be equal, so we have
2100 = 1/2 • 75 • CX → CX = 4200/75 = 56

A point is reflected over the y-axis, but the x-coordinate does not change. What is the location of the point ?
Answer:
(0, 3)
Step-by-step explanation:
Any point on the y-axis doesn't move when reflected across the y-axis. The x-coordinate must be zero. The only choice with that x-coordinate is (0, 3).
