Answer:

Obtuse  

Step-by-step explanation:

Plugging the numbers into the Pythagorean Theorem (a^2 + b^2 = c ^2)

20^2 = 12^2 + 15^2

400 > 144 + 225

400 > 369

Because of the Converse of the Pythagorean Theorem, which tells us if c is greater than a+b, it is obtuse

Mice21 [21]

Answer:

~~

Step-by-step explanation:

Ok so first 2.4 will have to be changed to 24 which means we multiplied it by ten making it 24/10 since it is tan it is opposite side/ adjacent side so your one of your legs will be 24 and one will be 10. Now we just plug that into the Pythagorean Theorem to find the hypotenuse and we get 26. The area is 24b10/2=120 the area is 120.

Leg a= 24

Leg b= 10

Hypotenuse=26

Area=120

A pipe is leaking at 1.5 cups per day. How many gallons per week is the pipe leaking?
neonofarm [45]
1.5 cups per day...7 days per week....1.5 * 7 = 10.5 cups per week
16 cups = 1 gallon

16/1 = 10.5/x....16 cups to 1 gal = 10.5 cups to x gal
cross multiply
(16)(x) = (1)(10.5)
16x = 10.5
x = 10.5/16
x = 0.65625 rounds to 0.66 gallons per week

If Anita has read 55 of the 245 pages in her book, what percent of the book has she read?
givi [52]

Answer:

22.45%

To two decimal places

Step-by-step explanation:

A book has 245 pages and she has only read 55 of the pages. To get the percentage:

55/245 and then multiply it by 100.

55/245

=O.2245 (To four decimal places)

0.2245 x 100

22.45% (To two decimal places)

She has only read 22.45% of the book. To convert it to a whole number, that's 22% of the book has been read
