This is the Equation: 2x + 6
Supplementary, and if they have a sum of 90 they are complementary.
Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
The 15% discount means that they only pay 100%-15% = 85% of the meal's bill.
This would cost 85% * 78.65.
However, they also have to pay a 20% tip of the meal cost.
This would cost 20% * 78.65.
Total Cost = (85% * 78.65) + (20% * 78.65)
= 105% * 78.65
= 1.05 * 78.65
= $82.58
Answer:
Step-by-step explanation:
(x+6)(x+4)(x-3)
= [(x+6)(x+4)](x-3)
= (x² + 4x + 6x + 24)(x - 3)
= (x² +10x + 24)(x - 3)
= x³ - 3x² + 10x² - 30x + 24x - 72
= x³ + 7x² - 6x - 72
