2 x ( 5 x 5 ) = 2 x 25 = 50

Blue side :

2 x ( 1 x 5) = 2 x 5 = 10

Green :

2 x ( 1 x 5 ) = 2 x 5 = 10

Total surface area:

50 + 10 + 10 = 70

Units : m²

Surface Area = 70 m²

Find $ \left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3} $.

vitfil [10]

Question:- Find

$\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}$

Answer:-

$\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}$

Taking power inside the bracket

$\frac{5^{4} }{ {12}^{4} } \times \frac{ {12}^{3} }{ {15}^{3} }$

$\frac{ {5}^{4} }{ {12}^{4 - 3} } \times \frac{1}{ {(5 \times 3)}^{3} } \\ \frac{ {5}^{4} }{12} \times \frac{1}{ {5}^{ 3 } \times {3}^{3} } \\ \frac{ {5}^{4 - 3} }{12 \times {3}^{3} } \\ \frac{5}{4 \times 3 \times {3}^{3} } \\ \frac{5}{4 \times {3}^{4} } = \frac{5}{4\times81 } \\ Answer-> \frac{5}{324}$

$Power\:Form-> \frac{ 5 }{12 \times {3}^{3} }$

the price for dinner in a resteraunt was $80. The customer paid an addition 7% meals tax and left a $15 tip. how much meals tax

Marrrta [24]

Multiply the price of the meal by the sales tax. Tips are added in after tax has been applied, so it would not be added in to calculate the tax.

Tax= Meal Cost * Tax %

=$80 * 7%
convert % to decimal (7% ÷ 100)

=80 * 0.07

=$5.60 sales tax paid

ANSWER: $5.60 was the sales tax the customer paid.
