Answer:
Step-by-step explanation:
Given the expression , to solve the expression, we need to write both scientific notation to the same power of 10.
The expression above becomes . On taking the difference;
The final expression gives the right answer
Formula Multiply the number by -3/4
The number 48 is 3/4 of 64 but it is negative so the result of -48 should be multiplying 64 by negative 3/4
64x-3/4 =-48
after 48 will be a positive number since (-)x(-)=(+)
So it will be alternating positive and negative
Answer:
Step-by-step explanation:
<u>Set inequality as per question:</u>
<u>We know that:</u>
- V = πr²h
- h = 10 cm
- π = 3.14
<u>Substitute and solve for r:</u>
- 2000 ≤ 3.14*10r² ≤ 2500
- 2000 / 31.4 ≤ r² ≤ 2500 / 31.4
- 63.69 ≤ r² ≤ 79.62
- 64 ≤ r² < 81
- r² = 64 ⇒ r = 8 cm is the possible radius
