Answer:

2) 520

3) 135

4) 490

5) 850

Step-by-step explanation:

2) 10 regular for every 2 premium. so 12 total. Then we do 624 divided by 12 so we get 52. So we multiply 10 by 52 and 520. So they have 520 regular subscribers.

3) 3 short sleeves for every 9 long sleeves. So 12 in total. 540 divided by 12 is 45. 45 times 3 is 135. So 135 short sleeves were sold.

4) 7 teens for every 2 adults. so 9 in total. 630 divided by 9 is 70. 70 times 7 is 490. So 490 of the people who voted were teens.

5) For every 10 songs he like there was 5 he disliked. So 15 in total. 1275 divided by 15 is 85. 85 times 10 is 850. He liked a total of 850 songs.

I hope I helped! <3

Sylvia read that the height of the Empire State Building is 443.2 m and wants to build a scale model of the building in her room

Answer:

Scale of 181: 1

Step-by-step explanation:

The first thing to do is to pass the feet by the meter, to work in the same units and thus create a consistent scale:

We know that one foot equals 0.3048 meters, therefore:

8 feet * 0.3048 meters / 1 foot = 2.4384 meters

So the scale would be:

443.2 / 2.4384 = 181.75

Which means that it is best to make a scale of 181: 1

Where 181 meters from the Empire State Building would equal 1 meter at home 0 181 inches would equal 1 inch at home

If a is an arbitrary nonzero constant, what happens to a/b as b approaches 0

Stolb23 [73]

It depends on how b approaches 0

If b is positive and gets closer to zero, then we say b is approaching 0 from the right, or from the positive side. Let's say a = 1. The equation a/b turns into 1/b. Looking at a table of values, 1/b will steadily increase without bound as positive b values get closer to 0.

On the other side, if b is negative and gets closer to zero, then 1/b will be negative and those negative values will decrease without bound. So 1/b approaches negative infinity if we approach 0 on the left (or negative) side.

The graph of y = 1/x shows this. See the diagram below. Note the vertical asymptote at x = 0. The portion to the right of it has the curve go upward to positive infinity as x approaches 0. The curve to the left goes down to negative infinity as x approaches 0.
