Answer:
The volume of the sphere is 
.
Step-by-step explanation:
The volume enclosed by a sphere is given by the formula
Where r is the radius of the sphere.
The diameter of a sphere is twice as long as any radius of the same sphere and is given by the formula
We know that the diameter of the sphere is 0.926 inch. The radius is
The volume of the sphere is
and rounding to the nearest thousandth we get .
Let the two number be x and y.
x+y=-1......i
2x+4y=-10.....ii
solving the simultaneous equation we have:
from equation i, making x the subject we get:
x=-1-y........iii
substituting iii in ii we get:
2(-1-y)+4y=-10
-2-2y+4y=-10
2y=-10+2
2y=-8
y=-8/2=-4
substituting the value of y in iii we get:
x=-1-(-4)
x=-1+4
x=3
therefore the first number is 3 and the second number is -4
Answer:
-2.5 + 2i.
Step-by-step explanation:
That would be (-9 + 4)/2 + (-i + 5i)/2
= -5/2 + 4i/2
= -2.5 + 2i (answer).
Answer:
yes
Step-by-step explanation:
according to cyclic quadrilateral properties the oppoaite angles are supplementry
Answer:
x = 14
Step-by-step explanation:
4x° + (3x + 20)° + (3x + 20)° = 180° (sum of interior angles; isocleces triangle)
10x + 40 = 180
10x = 140
x = 14
