Answer:

95

Step-by-step explanation:

Im pretty sure It's 95 because if you get a 90% on a test with 50 questions, you would've gotten 45 correct. If you get an 80% on a test with 50 questions, you would've gotten 40 correct. Then add them.

How many 2-digit numbers are among the terms of the arithmetic sequence 2, 7, 12, 17, ...?
Snowcat [4.5K]

Answer:

20

Step-by-step explanation:

It seems like the rule of this sequence is to add 5 (since 2 + 5 = 7 and 7 + 5 = 12). We already are given that we have 2 2-digit numbers (12 and 17) so let's see if there are any more. The sequence continues to 22, 27, 32, 37, 42, 47, ..., 92, 97. We need to count how many numbers are in the list 12, 17 ... 92, 97. To do this, let's add 3 to every term in the list to get 15, 20, ... 95, 100. Since the list is now full of multiples of 5 we can divide the list by 5 to get 3, 4, ... 19, 20 and then subtract 2 to get 1, 2, ... 17, 18 which means that there are 18 2-digit numbers.

The value of y varies directly with x. Which function represents the relationship between x and y if y=20/3 when x=30
kkurt [141]
Set it up as a direct variation: y/x=k, where k is the constant of variation. (20/3)/30=k gives us a k value of 8/9. The function would be y=8/9x
