Plug in your answer to the original equation. For example, if the equation is x+4=9, and I got 4, then you plug that in and find that it is wrong. So you then go back and fix your mistake.

Gnesinka [82]

Answer:

22.95 kg

Step-by-step explanation:

Let's say the farm stand owner starts with x kg of apples.

During the first hour, he sells 15% of the apples:

0.15 x

This means he's left with 85% of the original apples.  During the second hour, he sells 20% of the remaining apples:

0.20 (0.85 x)

= 0.17 x

He's sold a total of 15% + 17% = 32% of the apples, so he's left with 68% of the apples.  Continuing the pattern, the apples sold during the third hour:

0.25 (0.68 x)

= 0.17 x

He's sold 49% of the apples and is left with 51%.  The apples sold during the fourth hour:

0.30 (0.51 x)

= 0.153 x

If 0.17 x = 25.5, then x = 150.  So the apples sold during the fourth hour is:

0.153 (150) = 22.95

Solve these plz and give a explanation <br>​

Answer:

\large{ \tt{☄ \: EXPLANATION}} :

✎ Firstly , Remember these things :

  • To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : 12\% =  \frac{12}{100}  = \boxed{  0.12}

\large{  \tt{☥ \: LET'S \: SOLVE}} :

\large{1. \:  \: 52\%  \: \text{of} \: 210 =  \frac{52}{100} \times 210 = 0.52 \times 210 =  \boxed{109.2}  }

\large{ 2. \:  \: 35\%  \: \text{of} \: 500 =  \frac{35}{100}  \times 500 = 0.35 \times 500 =  \boxed{175} }

\large{3. \: 28\%  \: \text{of}  \: 866 =  \frac{28}{100} \times 866 = 0.28 \times 366 =  \boxed{102.48} }

\large{ \tt{✺ \: REPEAT \: DAILY} }:

  • I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.

ツ Hope I helped! ۵

Mary bought five pairs of socks that cost $8 each. if the tax rate was 8% how much did mary pay in total?
Zielflug [23.3K]

Answer:

The Answer would be $40.64

Step-by-step explanation:

To find a percentage of a certain number, you must multiply that number by the percentage in decimal form. Since the socks cost 8 dollars each 8 x 0.08 = 0.64 Meaning the tax cost is 64 cents. 8 x 5 = 40 Giving us $40.64
