Answer:
Need more information
Step-by-step explanation:
I need to know what percentage/fraction of the book she read in 1 hour or any other information about the rate she is reading
D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.
Set the two equations equal to each other and solve for X
Answer: 92
Step-by-step explanation:
Apply BODMAS
3×(24) -8) + 4 × (24-17)
3×24-8 +4×7
72-8 +28
64+28
92
Answer:
½bh units if height is known or
A = √S(s-a)+(s-b)+(s-c)units if height is not given. This is most definitely the right answer
Step-by-step explanation:
Hello,
In the question above, we don't have a dimension but we can solve this directly using it's formula and defining the angle
The triangle above is an isosceles triangle.
Isoscele triangles are triangles that have two of its side equal.
The area of a triangle is given as ½ × breadth × height.
The height can easily be calculated using one of it's slant height and it's breadth. This is done using pythagoras theorem. Which is given by
x² = y² + z²
In this case, the area of this triangle is ½b×h.
However, there are cases where by three sides are given known as a, b and c. We can easily use Heron's formula to find the area
A = √S(s-a)+(s-b)+(s-c)
Where s = (a + b + c) / 2
S = perimeter
