6% purchased model and 26% model b. Because you add up the all of the people who were and weren’t happy for both so it was 35 people in total.
So for a you divide 2 by 35 and then multiply that by 100 and then round and you get 6%
For b you divide 9 by 35 mult. By 100 and then round you get 26%
3p=p(1+0.06)^t
3=(1.06)^t
T=log(3)÷log(1.06)
T=18.9 years
2 classes of 21 students each
21 × 2 classes = 42 students in total
42 × 3 mins = 126 minutes for 42 students
10 mins for 2 class pics = 20 minutes
126 + 20 = 146 minutes = 2 hours and 26 minutes
It should take 146 minutes (2 hours and 26 minutes) to take all the pictures.
Answer:
$18.20/0.65=28 minutes
Step-by-step explanation:
$18.20 was the cost of the rental divide it by the cost per minute and that will give you the total number of minutes used which is 28.
Your answer would be 31.5 (so 32 when rounded up)
For triangles you basically multiply them together, and the divide your answer by two.
A= 1/2 b x h
A= 1/2 7 x 9
A= 1/2 63
A= 31.5 (rounded up to 32)
