Answer:
20
Step-by-step explanation:
the pythagorean theory a^2 + b^2 = c^2
16^2 + 12^2 =
144 + 256 = 400
sqr root of 400 is 20

The point-slope form:
We have m = 56 and the point (-8, -4). Substitute:
Answer:
$7.20
Step-by-step explanation:
8% as a decimal would be 0.08.
To find the sales tax, you would multiply 0.08(90)
0.08(90)=7.2
In dollars, that would be $7.20

Step-by-step explanation:
<u>Step 1: Define</u>
d = 19 cm
<u>Step 2: Find </u><em><u>SA</u></em>
- Substitute [R]: r = 19 cm/2
- Divide: r = 9.5 cm
- Substitute [SAS]: SA = 4π(9.5 cm)²
- Exponents: SA = 4π(90.25 cm²)
- Multiply: SA = 361π cm²
- Multiply: SA = 1134.11 cm²
- Round: SA ≈ 1134 cm²
