A cake has a mass of 2.5kg. It contains 275g of fruit. What percentage of fruit is there in the cake
Travka [436]
The answer is:  "11 %" . 
__________________________________
There is 11% of fruit in the cake.
______________________________
Explanation:
____________________________________

275g is what percent of 2.5 kg?  

First, convert "275 g" into "kg".

Note the exact conversion:  1000 g = 1 kg .  

So 275 g = (275/1000) kg  = 0.275 kg .


0.275 kg = (n/100) * 2.5 kg ; 

→ (n/100) * 2.5 = 0.275 ;
____________________________
Divide each side by "(2.5)" 
______________________
→ (n/100) = (0.275) / (2.5) ;

→ (n/100) = 0.11 ;

Multiply each side by "100" ; 

n = 11 . 
________________________________________
The answer is:  11 % .

18.) The cost of textbooks for a school increases with the average class size. Identify the independent and dependent quantity i
son4ous [18]

The independent quantity is the average class size and the dependent quantity is the cost ⇒ c

Step-by-step explanation:

Lets revise the meaning of dependent and independent variables

  • The dependent variable is the one that depends on the value of some other number
  • The dependent variable is the output value and the independent variable is the input value
  • Ex: if y = 2x + 3, x is the input and y is the out put, then is independent variable and y is dependent variable

∵ The cost of the textbook increases with the average class size

- The cost of the textbooks depends on the average of the

  class size

∴ The input is the average class size

∴ The output is the cost of the textbooks

∵ The input variable is independent variable

∵ The output variable is dependent variable

∴ The average of the class size is independent

∴ The cost of the textbooks is dependent

The independent quantity is the average class size and the dependent quantity is the cost

Explain e=mc(squared)
stepladder [879]
"Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.
