Okay. Let us do it surgically. Let us solve first the rate of increase in Lliana's Math grade. 86-65 = 21, thus the rate can be written as a fraction 21/65. We will reserve the decimal form once we are done with both rates of increase.
On the same note, Fiona's increase in Math grade is determined by subtracting 70 from her recent grade of 80, thus giving us an increase in her grade by 10. Therefore, the rate of increase in her Math grade is 10/70.
Now, let us take the decimal forms of the students' grade in math respectively. Lliana's is 21/65 or 0.32307692307... Fiona's is 10/70 or 0.14285714285. Now, subtracting this decimals we have 0.18021978021.
Changing it to percent form, we must multiply it by 100 and add the symbol "%". Therefore, we have 18.021978021 %.
Finally, rounding the value to the nearest whole number, we obtained 18.00% or just 18%.
Think about the way the cupcakes were set up...
Total cost + (cost per cupcake/cup of lemonade x # of cupcakes/cups of lemonade sold)
Revenue would be how much they’re charging for each cupcake/cup of lemonade x # sold
Answer:
536.52
Step-by-step explanation:
5.26x102=536.52
The answer is (4,5) Mark me brainliest!!!!!
Its defined only for three dimensional vectors.
it would be written as "a x b"
hoped this helped a bit
