Answer:
Step-by-step explanation:
Assumed the starting point is the sea level 0.
<u>After 2.8 min the diver is at position:</u>
- 20 1/2 * 2.8 =
- 20.5 * 2.8 =
- 57.4 feet below sea level
<u>The position change after next 2 minutes:</u>
<u>The position of the diver after 4.8 min:</u>
- 57.4 - 50 = 7.4 feet below sea level
Answer:
2.8
Step-by-step explanation:
0.2 (n -6) = 2.8 equation
An isosceles triangle is a triangle that has one pair of equal sides. The Formula in finding the perimeter of a triangle is PΔ=S₁+S₂+S₃. Since two legs are missing, and the given are the base and perimeter, we will use the formula : S₁+S₂ = PΔ-S₃, where: S₁+S₂ are the legs and <span>S₃ is the base.
Substitute values:
</span><span>S₁+S₂ = 43cm - 7 cm
</span> = 36 cm
since S₁ and S₂ are equal, divide 36cm by 2. Therefore S₁ and <span>S₂ measures 18cm.
Check: </span><span>PΔ=S₁+S₂+S₃
</span><span> = 18cm + 18 cm + 7cm
= 43cm

A shape that has four corners and four sides like a square, rectangle, or dimond
Answer:
3 machine
Step-by-step explanation:
It is given that 6 machine each working at the same rate can complete the work in 12 days
We the has to complete in 8 days
Let we need x extra machine to complete the work in 8 days
So total number of machines =x+6
Now according to man work day equation 
x=3 machine
