I really need help please c:
U^-3=1/125
U=?

Answers

Answer 1

Answer: $a^(-n)=(1)/(a^3)\n-----------------------\n\nU^(-3)=(1)/(U^3)\n\ntherefore\n\n(1)/(U^3)=(1)/(125)\ \ \ \ \ |inverse\ both\ sides\n\nU^3=125\n\nU=\sqrt[3]{125}\n\n\boxed{U=5}\ because\ 5^3=125$

Answer 2

Answer: the answer is: U =5

first, you take the U^-3 and put it as 1/U^3, that is because you cannot have a negative exponent, you MUST turn the exponent into a positive....
now you have 1/U^3 = 1/125... now you find the uncubed version of 125::::::

the cube root of 125 is 5

so, when you have U^-3, you are looking at 5^-3..

Amy bought 0.4 kg of tomatoes for $4.00.

What is the cost in dollars per kg of tomatoes?

Answers

Answer: The required cost in dollars per kg of tomatoes is $10 per kg.

Step-by-step explanation: Given that Amy bought 0.4 kg of tomatoes for $4.00.

We are to find the cost in dollars per kg of tomatoes.

We will be using the UNITARY method to solve the given problem.

The cost of 0.4 kg of tomatoes = $4.00.

Therefore, the cost of 1 kg of tomatoes is given by

$\$(4.00)/(0.4)=\$(40)/(4)=\$10.$

Thus, the required cost in dollars per kg of tomatoes is $10 per kg.

if 0.4 kg cost 4. 0 dollar
than 1.kg will cost x dollar

x = (1 * 4)/0.4 = 10 dollars

1 kg tomatoes cost 10 dollars

Help would be nice :p *pls don't leave this qestion.....I will cry :|*Which is the best description of the equivalency of the two expressions?

Expression 1
5 x squared minus 2 x minus 4 + 6 x + 3
Expression 2
6 x squared minus 6 x + 6 minus x squared + 10 x minus 7

A.) The two expressions are not equivalent because when x = 2, the two expressions do not have the same value.

b.)The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for the x squared and x terms.

c.) They are equivalent because the sum of the constants is the same in both expressions.

D.) They are equivalent because when x = 2, the two expressions have the same value.
