Answer:
5y=2
Step-by-step explanation:
8y + 4 = 6 + 2y + 1y
Combine like terms
8y+4 = 6+3y
Subtract 3y from each side
8y-3y+4 = 6+3y-3y
5y +4 = 6
subtract 4 from each side
5y+4-4 = 6-2
5y=2
Answer: 102°
Step-by-step explanation:
First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.
Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:
t + 39° + 39° = 180°
t + 78° = 180°
t = 180° - 78°
t = 102°
The third angle is 102°.
The word inscribed means that the sphere is inside the cylinder and its diameter is equal to the height and diameter of the cylinder. The surface area of the sphere is equal to
SA (sphere) = πd²
where d is the diameter.
That of the cylinder is,
SA (cylinder) = πd(h + d/2)
Since h is also equal to d
SA (cylinder) = πd(d + d/2) = 3πd²/2
Therefore, the surface area of the cylinder is approximately 1.5 times that of the sphere.
Answer:
No solution
Step-by-step explanation:
2(9x-5)=6(3x+4)
Step 1 is to do distributive property.
so you will get this:
18x-10=18+24
step 2 is combining like terms.
so you will subtract 24x from both sides.
(this:) 18x-10=18x+24
(into this:) -10=24
I got this because when you subtract 18 from 18 you will get zero (0).
So your answer will be:
No solution
Around 4.5π. This can be determined by the volume of a sphere formula.
