Answer:
-2 and 2/3
Step-by-step explanation:
(2/3) / (-1/4) is equivalent to (2/3) x (-4/1)
This equals -8/3, of which simplifies down to -2 and 2/3
answer: i think that it would increase by about 20 percent
i am not sure, if i m wrong then i am very sorry!
Step-by-step explanation:
The question mark is equal to -5 and if you need f than f is equal to -15
The <em><u>correct answer</u></em> is:
negative six and thirty-three fortieths
Explanation:
To multiply (2 5/8)(-2 3/5), we first change each mixed number to an improper fraction. To do this, we multiply each whole number by the denominator and add the numerator:
(2*8)+5 = 16+5 = 21; this makes 2 5/8 = 21/8
(2*5)+3 = 10+3 = 13; this makes -2 3/5 = -13/5
This gives us
(21/8)(-13/5) = (21*-13)/(8*5) = -273/40
40 will go into 273 6 times; this gives us the number -6. There is then 270-240 = 33 left over; this gives us 33/40, and a total of -6 33/40.
Answer: 
Step-by-step explanation:
For this exercise you need to apply the Pythagorean Theorem. This is:
Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.
In this case, you can identify that:
Knowing these values, you can substitute them into :
Now you must solve for "c":
Evaluating, you get:
To simplify the result:
- Descompose 32 into its prime factors:
- By the Product of powers property, you know that:
- Make the substitution:
- Finally, knowing that ![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
, you get:
