Answer:
2
Step-by-step explanation:
Answer:
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
To divide the expression we proceed as follows:
12x⁴y²÷3x³y⁵
=12x⁴y²/3x³y⁵
=(12÷3)×(x⁴÷x³)×(y²÷y⁵)
when you divide number with the same base, you subtract the numerators:
=4×(x⁴⁻³)×(y²⁻⁵)
simplifying this we get
=4xy⁻³
Answer: 4xy⁻³
Answer:
B
Step-by-step explanation:
-8+2=-6 and im pretty sure negative of a power is just a regular power so its B
Answer:
D or 11/12
Step-by-step explanation:
5/8 + 3/4 / -2/3 - 5/6
= 11/8 / -9/6
= 66/72
= 22/24
= 11/12
