Step-by-step explanation:
first, you need to know the formulas for volumes for a sphere, cone, and cube.
sphere volume is defined: V=4/3πr^3
cone volume is defined: V=πr^2(h
/3)
cuboid volume is defined: V=lwh
Then just plug in:
sphere volume=4/3π6^3=904.78
cone volume=π5^2(13
/3)=340.34
cuboid volume=11*6*5=330
Given:
BD is parallel to XY.
One of the angle is 85°
To find:
The value of y.
Solution:
Parallel lines BD and XY cut by a transversal line.
Angle y and 85° are alternate interior angles.
Alternate interior angle theorem:
If two parallel lines are cut by a transversal line, then the pairs of alternate interior angles are congruent.
⇒ y = 85°
The value of y is 85.
So 7 friends with similar. Phone plans. 3 of them pays an extra 4 bucks, so that means that x+ 4 is what 3 of the 7 r paying. The other 4 pay just x Amt of money for their plan. So go find the total bill, it would be (x+4)+(x+4)+(x+4)+x+x+x+x. Now simplify, (x+4)^3, because there are three of the 7 using that, and then x^4, because 4 of the 7 r using that plan. So in total it would be (x+4)^3+ x^4. Hope this helps
