Answer:
The number of 57-cent stamps that Julie bought is 12
Step-by-step explanation:
Given equation
0.57 s + 0.3 ( s − 6 ) = 8.64
Open bracket
0.57s + 0.3s - 1.8 = 8.64
Collect like terms
0.87s = 8.64 + 1.8
0.87s = 10.44
Divide both sides by 0.87
s = 12
The number of 57-cent stamps that Julie bought is 12
38.5-31.57=6.93 meaning 6.93/38.5 = .18 = 18%
Answer:
The answer is 105.5 kcal/slice of bread.
Step-by-step explanation:
The kcal per gram of:
- protein = 4kcal/g.
- carbohydrate = 4kcal/g.
- fat = 9kcal/g.
Now, you have:
- 1.5 g of fat + 19g of carbohydrate + 4g of protein = 1 slice of bread.
If we multiply the amount of components by his kcal:
- 1.5g * 9kcal/g + 19g * 4kcal/g + 4g * 4kcal/g;
Now gram/gram = 1, and we can cancel the grams in the equation:
- 1.5* 9kcal + 19 * 4kcal + 4 * 4kcal = 105.5kcal;
Finally, the result of the kcal of the slice bread is:
- 105.5 kcal/slice of bread.
Answer:
3) 5
Explanation:
Use Pythagoras Theorem where
a^2 + b^2 = c^2
3^2 + 4^2 = 25
C= root 25 = 5
