Maria's kite tail was 3 1/2 feet long. Max's kite tail was 2 1/4 feet long. How much shorts was max's kite tail in inches?
8090 [49]

Answer: \frac{5}{4}\ ft

Step-by-step explanation:

Given

Maria kite tail is 3\ \frac{1}{2}\ ft long

Max's kite tail is 2\ \frac{1}{4}\ ft long

Converting it to a fraction

Maria kite tail

\Rightarrow \dfrac{3\times2+1}{2}=\dfrac{7}{2}\ ft

Max's kite tail

\Rightarrow \dfrac{2\times4+1}{4}=\dfrac{9}{4}\ ft

Difference between lengths

\Rightarrow \dfrac{7}{2}-\dfrac{9}{4}\\\Rightarrow \dfrac{14-9}{4}=\dfrac{5}{4}\ ft

Max's tail is \frac{5}{4}\ ft short than Maria kite tail

Can someone check this one for me , thank you!
Rudik [331]

Answer:

C

Step-by-step explanation:

Using sum/difference to product identity

• sin x - sin y = 2 cos(\frac{x+y}{2}) sin (\frac{x-y}{2})

with x = 4Θ and y = 2Θ

Then

sin(4Θ) - sin(2Θ)

= 2 cos(\frac{4o+2o}{2}) sin(\frac{4o-2o}{2})

= 2cos(3Θ)sinΘ → C
