Answer:
720 miles
Step-by-step explanation:
180mi/2.5hr=72 mph
72mph (10hr)=720 miles
$1100 - $160 = $940
$940 ÷ 8 ≤ $117.50
Greatest amount to the nearest dollar = $117
Answer: $117
Step-by-step explanation:
you cannot just put the actual numbers in and calculate ?
and you can't provide the correct problem statement, as it seems.
I assume you mean
an = 3n² - 1
a sequence starts with a1, so, n>=1
a1 = 3×1² - 1 = 3-1 = 2
a2 = 3×2² -1 = 3×4 - 1 = 12 - 1 = 11
a3 = 3×3² - 1 = 3×9 - 1 = 27 - 1 = 26
a4 = 3×4² - 1 = 3×16 - 1 = 48 - 1 = 47
a5 = 3×5² - 1 = 3×25 - 1 = 75 - 1 = 74
there, that is all there is to it. you really needed help with that ?
A is 45 b is 90 and c if 90
The answer is C 66 square inches
