During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the rem
Lelechka [254]

Answer:

200 kg


Step-by-step explanation:

First hour he sold 15% <em>(remaining is 85%)</em>

Second hour he sold 20% of remaining <em>(which is 85%)</em> -- so he sold (0.2)(0.85)=0.17, which is 17% (remaining 85-17=68%)

Third hour he sold 25% of remaining <em>(which is 68%)</em> -- so he sold (0.25)(0.68)=17, which is 17%


In third hour he sold 34, so 17% is 34. To find total he initially had, we need to find (100%). We can setup the ratio (letting x equal his initial amount):

\frac{0.17}{34}=\frac{1}{x}\\0.17x=34\\x=\frac{34}{0.17}=200

Initially the farm stand owner had 200 kg of apples.

Ur answer will be marked as brainliest...
Julli [10]

Answer:

92.75 cm^2

Step-by-step explanation:

Area of triangle ADC

= (1/2)×4.5×12 = 27

Area of triangle ACB

=(1/2)×12×5 = 30

Find AB using pythagoras theorem on triangle ABC:

AB^2 = 5^2 + 12^2 = 25 + 144

AB^2 = 169

AB = 13cm

Area of triangle AGB

= (1/2)×13×5.5 = 35.75

Total area = sum of the areas of the 3 triangles found above

= 27 + 30 + 35.75 = 92.75 cm^2
