If Gina has $90 and pays:

$20 for beginning
$5 per hour

Then 90 - 20 is 70. 70 divided by 5 is 14.

She can rent a surfboard to surf for 14 hours.

Help me quickkkk!!<br> A = 1/2(a+b)h solve for b
nasty-shy [4]

Answer:

2A/h - a = b

Step-by-step explanation:

Using A= 1/2(a+b)h

Divide both side by h

⇒A/h = 1/2(a + b)

Mutiply both sides by 2

⇒2A/h = a + b

Take the 2 over to the other side

2A/h - a = b

Keep in mind, that the (a) is not on the bottom, rather on its own

Dexter has 83 tiles left over from tiling his bathroom floor and he would like to use them to tile the front entrance of his hou
creativ13 [48]

Answer: [0, 396]

Step-by-step explanation:

The domain is the acceptable values of x in the function.  In this case, x = t, the number of tiles.  If you think about it, the minimum number of tiles is 0 (you can't have a negative number of tiles), and the maximum number of tiles is 44 (you only have 44 tiles).  So, the domain for this function is from 0 to 44.

0 to 44 written in interval notation is [0,44].

The range is the acceptable values of y in the function.  In this case, y = A, the area given.  A(t) = 9t, so you can use the acceptable values of t to get the range.  Again, the minimum area is 0 because you can't have negative area. To find the maximum area, plug in the maximum number of tiles: 9.

A(t) = 9t

A = 9(44)

A = 396

With the maximum number of tiles, 44, the area you get is 396 cm².  Therefore, the acceptable values of A are from 0 to 396.

0 to 396 written in interval notation is [0, 396].
