7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
Answer:
1) Equation: x/3 + 8 = 36
(x = ticket cost)
Solution: x = $9.33
2) Equation: 4 + 8x = 36
(x = number of games played)
Solution: x =
Step-by-step explanation:
x + 8 = 36
<u> -8 -8 </u>
x/3 = 28
divide by 3
x = $9.33
_______________________
4 + 8x = 36
<u>-4 -4</u>
8x = 32
divide by 8
x = 4
They bowled 4 games
Answer:
between 45% and 51%
Step-by-step explanation:
Data provided:
Margin of error = plus or minus 3%
Confidence level = 95%
Number of voters asked = 1,000
Respondents considered themselves independent = 48%
Now,
adjusting the margin of error in the result
we get
the range as:
lowest value of range percentage of independents among voters in Maine
= 48% - 3%
= 45%
and,
Highest value of range percentage of independents among voters in Maine
= 48% + 3%
= 51%
Hence,
the percentage of independents among voters in Maine are between 45% and 51%
