Pretty sure the answer would be 16.
Because 7.6 rounds to 8 and 1.4 would round up to 2. Then you multiply 8 & 2 and get 16.
Take the root of both sides and solve.
Answer:
r = 3.
Step-by-step explanation:
16 = 10 + √(3r + 27)
√(3r + 27) = 6
Square both sides:
3r + 27 = 36
3r = 36 - 27 = 9
r = 3.
Check the result:
Left side of the equation = 16
Right side = 10 + √(9 + 27)
= 10 + √36 = 16
Answer:
0.0325
Step-by-step explanation:
3.25% = 3.25 over 100 or,
3.25%=3.25100
3.25 over 100 is the same as 3.25 divided by 100. Completing the division we get:
3.25 ÷ 100 = 0.0325
Therefore, we have shown that
3.25% = 0.0325
