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

B.

Bread baked at 325 F has an average density of 0.42 g/cm^3.

As the temperature increases, the density decreases.

The answer is B. "Bread baked at 325 °F has an average density of 0.42 g/cm³. As the temperature increases, the density decreases."

If you closely observe the table, you can see that the density starts at 0.42 and as the temperature increases, the density decreases, with the final density being 0.26 g/cm³.

Options C and D are invalid because the table only gives information about the temperature and the density, not the amount of time taken for the bread to bake.

Can someone plz help me. How can you find the inequalities of 11/15 and 5/7. Next 5/9 and 7/13. Next 11/15 and 5/7. Lastly 5/9 and 7/13. PLZ HELP.

Answers

To make this a little clearer, let's give the pairs of inequalities the same denominator:

Question 1:
$(11)/(15)$ ? $(5)/(7)$
First, apply the common denominator to the first fraction:
$((11)/(15))7 \n (11)/(15) * (7)/(7) \n (11*7)/(15*7) \n (77)/(105)$
Do the same for the second: $15( (5)/(7)) \n (5)/(7)* (15)/(15) \n (5*15)/(7*15) \n (75)/(105)$
Nest, compare the two fractions:
$(77)/(105) \ \textgreater \ (75)/(105)$
Therefore:
$(11)/(15)$ > $(5)/(7)$

Question Two:
$(5)/(9)$ ? $(7)/(13)$
Apply the common denominator to fraction one:
$13( (5)/(9)) \n (5)/(9) * (13)/(13) \n (5*13)/(9*13) \n (65)/(117)$
Fraction two:
$9((7)/(13)) \n (7)/(13) * (9)/(9) \n (7*9)/(13*9) \n (63)/(117)$
Evaluate:
$(65)/(117)$ > $<span>(63)/(117)$
Therefore:
$(5)/(9)$ > $(7)/(13)$

Hope this helps!
