The time taken by the rock will be 8.77 seconds.
<h3>What is speed?</h3>
Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
Given that:-
The equation for free fall at the surface of some planet (s in meters, t in seconds) is s = 2.86t²
The time will be calculated by using the speed formula.
Speed = Distance \ Time
25.1 = 2.86t² \ t
t = 25.1 / 2.86
t = 8.77 seconds
Therefore the time taken by the rock will be 8.77 seconds.

Answer:
B. 1/10 the value of
Step-by-step explanation:
In our base-10 place-value number system, the place value of a number is multiplied by 10 when it moves 1 place to the left. It is multiplied by 1/10 when it moves 1 place to the right.
A digit has 1/10 the value of the same digit one place to its left.
The number of squares of whole pita bread Min will have to cut up is;
<u><em>21 squares of whole pita bread</em></u>
- Since the triangle is isosceles, and has base of 4 cm with 2 equal sides of 6 cm, it means the height is 5.7 cm.
- Thus, area of triangle is;
A = ¹/₂ × 4 × 5.7
A = 11.4 cm²
- She will cut 3 pita triangles for every guest. This means that;
Area for each guest = 3 × 11.4 = 33.2 cm²
- There are 250 guests and so the total needed for the 250 guests is;
Total area = 250 × 33.2
Total area of pita bread = 8300 cm²
- The bread comes in 20 cm sides of a square shape.
Area of square = 20 × 20 = 400 cm²
- Number of squares of whole pita bread she will have to cut = 8300/400
⇒ 20.75 ≈ 21 squares of whole pita bread
