The sides of a right triangle are x, x+21, and x+27. what is the length of the hypotenuse
mina [271]
Answer: 51 uinits

The three numbers are x , x + 21 and x + 27. 
The greatest of the 3 numbers is x + 27, so x + 27 has to be the hypotenuse.

----------------------------------------------
Pythagoras Theorem
----------------------------------------------

a² + b²  = c²

x² + (x+21)² = (x+27)²

x² + x² + 42x + 441 = x² + 54x + 729

x² - 12x -288 = 0

(x - 24)(x + 12) = 0

x = 24 or x = -12 (rejected, length cannot be negative)

----------------------------------------------
Find hypotenuse
----------------------------------------------
 Hypotenuse = x + 27 = 24 + 27 = 51 units

-----------------------------------------------
Answer: 51 units

Fernando bought 8 pints of milk. How many fluid ounces of milk did Fernando buy?
nordsb [41]

Answer: 128 fluid ounces

Step-by-step explanation:

First and foremost, we need to realize that:

1 pint = 16 ounces

Therefore, since Fernando bought 8 pints of milk, to convert it to ounces, we just have to multiply 16 by 8. This will be:

= 16 ounces × 8

= 128 ounces

The scale of a map is 6 km = 4 mi. What is the length on the map if the actual is 40.1<br> miles.
beks73 [17]

Answer:

60.15 km

Step-by-step explanation:

If 6 km on the map represents 4 mi on land, then we'd get the answer by using the relation

6 km -> 4 mi

x km -> 40.1 mi

Where x km is the length on the map we're looking for. If we cross multiply

6 * 40.1 = 4x

240.6 = 4x

x = 240.6/4

x = 60.15 km.

That is the length we're looking for
