A space plane skims the edge of space at 4000 miles per hour. Neglecting altitude, if the circumference of the planet is approx

posledela

Answer:

6 hour 20 minutes

Step-by-step explanation:

We are given that a space plane skims the edge of space at 400 miles per hour.

Circumference of the planet=25000 miles approximately

We have to find the time taken by the plane to travel around the planet.

Speed of plane=4000 miles per hour

Total distance traveled by the plane= approximately 25000 miles

Because plane travel in circular path therefore, distance

traveled by plane=Circumference of planet

Time = $\frac{distance}{speed}$

Substitute the values then we get

Time = $\frac{25000}{4000}=\frac{25}{4}=6\frac{1}{4} hours$

Time= $6 hour +\frac{1}{4}\times 60 minutes= 6\;hour\;20 minutes$

1 hour=60 minutes

Hence, the plane takes time to travel around the planet=6 hour 20 minutes

A lawn sprinkler sprays water 5 feet in every direction as it rotates. What is the area of the sprinkled lawn?

Ann [662]

So if the lawn sprinkler rotates in a circular motion, then what you're left with is a circle with a radius of 5 feet. You can then just use the formula Area = π × radius^2 to do π × 5^2 = 25π = 78.5 feet^2. I hope this helps!

Thirteen plums weigh as much as two apples and one pear. Four plums and one apple have the same weight as one pear. How many plu

cluponka [151]

Let U be plums, A be apples and P be pears.
13U = 2A + P
4U + A = P

Substituting P from the second equation to the first:
13U = 2A + 4U + A
9U = 3A
A = 3U

Now, substituting the value of A into the second equation:
4U + 3U = P
7U = P
7 plums weigh the same as one pear.

Which step is the same when constructing an inscribed regular hexagon and an inscribed equilateral triangle?.

Naddik [55]

Step is the same when constructing an inscribed regular hexagon and an inscribed equilateral triangle is shown below:

<h3 /><h3>What is construction?</h3>

Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler.

Construction of an inscribed regular hexagon

1) Set compass width to the radius of the circle

2) Make an arc on the circle with the set radius.

3) From the previous arc draw another arc with the same radius.

4) Continue this process for the other vertex.

5) Connect all the vertices.

Construction of an inscribed equilateral triangle

1) Set compass width to the radius of the circle

2) Make an arc on the circle with the set radius.

3)From the previous arc draw another arc with the same radius.

4)Continue this process for the other vertex.

5) Connect the every other vertices point by drawing a line between every other adjacent vertex point to form an inscribed equilateral triangle.
