Answer:
18=x*.20
15=x*.25
12=x*.30
24=x*.40
39=x*.60
78=x*.30
Step-by-step explanation:
To solve for x on each, divide the number on the left of the equal side by the number x is being multiplied by. For example, 18/.20=x
This is the concept of volume of solid materials, we are required to find the diameter of cone with height 8 and volume 150 m^3.
volume of cone is given by;V=1/3 (pi*r^2*h)
making r^2 the subject we get;
V/(pi*h)=r^2
inserting the values in our formula we get:
150/(pi*8)=r^2
r^2=5.97
thus;
r=sqrt(5.97)=2.44
But ;
diameter=2*radius
thus
diameter=2.44*2
=4.88 m
**4/5** is equal to .8, so 4/5 is the answer. to check, multiply .8 x 5 = 4
Now CHECK by substituting into the angles in your question, 8(17-10)=56 and 90-34=56, so x=10 and y=17, and they each make up the angle of 56 degrees
The place value is 6 Hundred million.
