Answer:

x=22

Step-by-step explanation:

To solve, use an important geometry theorem.

  • The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Know this theorem, write 6x-7 = 103-x+2x and solve for x.

6x-7=103-x+2x

6x-7=103+x

5x-7=103

5x=110

x=22

A microscope was originally priced at $100 but went on sale for 10% off. If Adele bought the microscope and paid 10% sales tax,
AfilCa [17]

Answer:

$99

Step-by-step explanation:

First, it was on sale for 10% off. 10% = 0.1 = 1/10. 1/10 of 100 is 10, so we subtract 10 (because 10% off) to get $90. Then, the sales tax, which we add, is 10%. 1/10 of 90 is 9, so we add 9 to 90 to get our total to be $99

marissa [1.9K]
The formula is V = (4/3) pi * r^3
r = 10 cm^3 = 1000 cm^3 That let's out D
V = (4/3) * 3.14 * 1000
V = (1.3333) * 3.14 * 1000
V = 1333 * 3.14
V = 4185 cm^3
