The answer is A. f(x)= -1/2x + 4 because it’s 4-2=2 over 0-4= -2 equal -1/2
Answer:
7.5
Step-by-step explanation:
given:
3/4 = x/10 (multiply both sides by 10)
(3/4)(10) = x
x = 30/4
x = 7.5
Answer: 
Step-by-step explanation:
Answer:
7.57 cm
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
r= radius
h = height
1,800 = 3.14 x r² x 40
r² = 1800 /(3.14 x 40)
r² = 14.33121
√14.33121 = r
r = 3.785658 cm
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
Diameter = 2 x 3.785658 cm = 7.57cm
Answer:
Step-by-step explanation:
Given data
breadth=9 in
Length=11 in
Now a square of side x is cutted for each corner such that the cardboard is made into a open-top box with
length=11-2x
breadth=9-2x
height=x
Here substract 2x because from both sides of length and breadth x units are reduced.
therefore volume of new open-top box is
Volume(v)=
