If a track is 400 meters around, how many laps around the track would it take to run 3.1 miles round to the nearest tenth
Answer:
Step-by-step explanation:
12.5
Number of laps in given distance is 12.5 laps.
Given:
Length of a track = 400 meter
Total distance = 3.1 miles
Find:
Number of laps in given distance
Computation:
We know that
1 miles = 1609.34 meter
So,
Total distance = 3.1 miles
Total distance = 3.1 × 1609.34
Total distance = 4988.954
Number of laps in given distance = 4988.954 / 400
Number of laps in given distance = 12.4723
Number of laps in given distance = 12.5 laps (Approx.)

A building has the shape of a pyramid with a square base. The midsegment parallel to the ground of each triangular face of
the pyramid has a length of 58 feet. The perimeter of the base of the pyramid is
feet.
Answer:
The length of the base the pyramid is 116 feet.
Step-by-step explanation:
See the diagram attached to this answer.
Let Δ OAB is the side triangle of the square pyramid, and A'B' is the mid segment parallel to the ground with length of 58 feet.
Now, Δ OAB and Δ OA'B' are similar triangle and the length of sides of the triangle Δ OA'B' are in the same ratio with the corresponding sides of Δ OAB.
Hence,
⇒ AB = 2 × 58 = 116 feet.
The length of the base the pyramid is 116 feet. (Answer)

A circle is centered at the point O (0,0) and has a radius of the square root of 38?
Where’s does the K (6,1) lie?
Answer:
The point (6,1) lies inside the circle.
Step-by-step explanation:
Equation of a Circle
A circle centered at the point (h,k) and with radius r, can be expressed with the equation:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
The center of the given circle is (0,0) and the radius is [tex]r=\sqrt{38}[/tex], thus the equation of the circle is:
[tex](x-0)^2+(y-0)^2=(\sqrt{38})^2[/tex]
Simplifying:
[tex]x^2+y^2=38[/tex]
Each point (x,y) meeting the condition of the equation lies exactly on its circumference. For example, the point [tex](\sqrt{2},6)[/tex] belongs to the circumference, but the origin (0,0) is inside the circle, and the point (5,5) is outside the circle.
We can tell the difference by evaluating the equation at each point. For the first point [tex](\sqrt{2},6)[/tex], the equation is:
[tex](\sqrt{2})^2+6^2=2+36=38[/tex]
The equation is satisfied.
For the origin (0,0):
[tex]0^2+0^2=0[/tex]
For the point (5,5):
[tex]5^2+5^2=50[/tex]
We can conclude that if the left side is greater than 38, the point is outside the circle, if it's less than 38, the point is inside the circle.
Let's test the point (6,1):
[tex]6^2+1^2=37[/tex]
The point (6,1) lies inside the circle.

Answer:
Charles: 17 points
Adam: 25 points
Bethany: 30 points
Answer:
Adam scored 25 points.
Bethany scored 30 points.
Charles scored 17 points.
Step-by-step explanation:
A = Adam, B = Bethany, C = Charles
What we know:
C + 8 = A
A + 5 = B
A + B + C = 72
Charles:
C + 8 + 5 = B
C + (C + 8) + (C + 13) = 72
72 - 8 - 13 = 51
51/3 = 17
Charles scored 17 points.
Bethany:
17 + 13 = 30
Bethany scored 30 points.
Adam:
17 + 8 = 25
Adam scored 25 points.

Solve the equation for h and r. x= r-h/y
[tex]r \times x = \frac{r - h}{y} \\ [/tex]
Multiply sides by y
[tex]r \times x \times y = r - h[/tex]
Subtract sides minus r
[tex]r \times x \times y - r = - h[/tex]
Multiply sides by -1
[tex] - r.x.y + r = h[/tex]
Factoring r
[tex]h = r(1 - x.y)[/tex]
