It would be best to keep it the same. So if I knew the hypotenuse was 9 and that one side was 4 and I was looking for the other one I would right it like this:

4^2 + B^2 = 9^2
Then simplify
16 + B^2 =81
Then subtract
B^2 = 65
And then take the square root of both sides
<span>B = 8.0622577483 (since I came up with random numbers it ended up so uneven :P)


Does that make sense to you? I hope that helped you to understand! Feel free to let me know if you have any questions!

What is the surface area of the prism in square inches?
Snowcat [4.5K]

Answer:

176

Step-by-step explanation:

You multiply the length by the width to know the area or a square/rectangle (2D), so you multiply length by width by height to know the volume of a prism (3D). so 11*2"8=176

Dennis sister charges 550 per hour before 9 p.m. for babysitting and $8 per hour after 9 p.m. she finished babysitting at 11 p.m
LiRa [457]
Since we know what time Dennis' sister finished babysitting, we can calculate how much money she's made since 9p.m. Between 9 and 11 is 2 hours, so we know she made $16 ($8 per hour x 2 hours).

That means she made $22 before 9p.m. ($32 total - $16 made past 9p.m.)

So, you just need to figure out how many hours $22 is worth and subtract that number of hours from 9p.m. That will get you to the starting point of babysitting.

$22 / $5.50 = 4     so we know that $22 is 4 hours' worth of babysitting.

9p.m. - 4 hours is 5p.m., so we know that Dennis' sister started babysitting at 5p.m. 

Hope this helps! If you liked this answer please rate it as brainliest!! Thank you!!!

Alex is buying a sweater that originally costs $35 and a pair of jeans that originally cost $28.If the sweater is marked down 30
Sladkaya [172]

Answer: $47.66

Step-by-step explanation:

The cost of the sweater is calculated by multiplying .7 x $35. (70% represents the cost of the sweater since there is a 30% discount.). The sweater cost $24.50.

The cost of the jeans is .85 x $28 = $23.80.

The total cost is $24.50 + $23.80 = $43.80.

The tax rate is 8%, which is calculated by multiplying .08 x $43.80 = $3.86 in sales tax.

Including the sales tax, the total cost is $43.80 + 3.86 = $47.66
