A picnic table was originally priced at 40, but Megan waited to buy the picnic table on sale from 75% off. If she paid 10% sale
Mila [183]

<u>Answer:</u>

she spent total price of 13 on the picnic table

<u>Explanation: </u>

Original price of the table = 40

Since she paid 10% of the sale tax after the sale then the total amount she spend is  

Discount = (discount percentage – sale tax  ) × original price

=  (75% -10%) × 40

= 65 % ×40

=\frac{65}{100} \times 40

=26

Hence after the discount amount  

Original price – discount price

= 40-26 = 13

Hence she spent total price of 13 on the picnic table

Helen [10]

Step 1.

Calculate measure of angle α:

47^o-38^o=9^o

Step 2.

Calculate what fraction of the angle 360° ​​is the angle α:

\dfrac{9^o}{360^o}=\dfrac{1}{40}

Step 3.

Calculate the circumference of the Earth (circle):

C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi

Step 4.

The length of arc is equal 1/40 of the circumference:

\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi

\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi
