Answer:
x = 20
Step-by-step explanation:
Simplifying
1250 + 27.50x = 1400 + 20x
Solving
1250 + 27.50x = 1400 + 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
1250 + 27.50x + -20x = 1400 + 20x + -20x
Combine like terms: 27.50x + -20x = 7.5x
1250 + 7.5x = 1400 + 20x + -20x
Combine like terms: 20x + -20x = 0
1250 + 7.5x = 1400 + 0
1250 + 7.5x = 1400
Add '-1250' to each side of the equation.
1250 + -1250 + 7.5x = 1400 + -1250
Combine like terms: 1250 + -1250 = 0
0 + 7.5x = 1400 + -1250
7.5x = 1400 + -1250
Combine like terms: 1400 + -1250 = 150
7.5x = 150
Divide each side by '7.5'.
x = 20
Simplifying
x = 20
Answer:
A reflection across the x axis
Step-by-step explanation:
Parallelogram ABCD was reflected across the x axis to create parallelogram A'B'C'D'
The volume of the outer layer is 2670.57 cubic centimeters.
Given
The aspherical object has a diameter of 18 cm.
It has a spherical inner core with a diameter of 9 cm.
<h3>The volume of outer layer;</h3>
The volume of the outer layer is given by the following formula;
The volume of the outer layer is given by;
Entire sphere - Inner sphere= Outer layer
Radius of Entire sphere = 9 cm
Radius of Inner sphere = 4.5 cm
Therefore,
The volume of the outer layer is;
Hence, the volume of the outer layer is 2670.57 cubic centimeters.
