Answer:
d = 289
Step-by-step explanation:
The circumference is given by
C = pi *d
907.46 = pi *d
Using 3.14 for pi
907.46 = 3.14 d
Divide each side by 3.14
907.46 /3.14= 3.14 d/3.14
289 = d
Answer:
I think its y^-3
Step-by-step explanation:
Since y^-3/y^-2 are both negatives they would swap places to become positive - y^2/y^3
then using rules of exponents you would subtract the exponents witch would be y^-3
Step-by-step explanation:
a) 4x + 8 - 2x + 7
= 2x +15
b) 2n × 5 × 2a
= 10n × 2a
= 20an
Divide 2 feet into groups of 6 inches and get 4 groups. multiply 128 by 4 and 512 for your distance
