Okay. So, she buoyant 5.65 lbs of roast beef for $4.50. Multiply both of those numbers to get 25.425 or 25.43 when rounded to the nearest hundredth. So the total cost was $25.43. However, we now have to divide the amount by 6.5. 25.43/6.5 is 3.912 and other odd numbers or 3.91 when rounded to the nearest hundredth. The cost per sandwich was $3.91.

As a waitress, at the end of the night you have to tip 3% (same as 1/33) of your total earnings to the bussers and hosts.

equation:
total earnings (E) times (3% or 1/33)= money tipped to bussers and hosts(T).

E*1/33=T

a 175cm tall student casts a shadow that is 2.3cm long. at the same time, a tree casts a shadow that is 8.2m longest
Anika [276]

Ok so I’m assuming the question is how the tall is we need to find the Angle of the sun so

Student : 175

Shadow: 2.3

Hypotenuse: 175.0151136

Using -cos(175/175.0151136) we find the

Suns angle: .753 Above him/her

Our tree’s shadow:8.2

Using the suns angle we use cos(x

Please explain in detail how you solved.​
Alex17521 [72]

Step-by-step explanation:

Since this is a right triangle and we are given an angle measure that measure 45, the other angle measure also measure 45.

So this means we are dealing with a 45-45-90 triangle.

A 45-45-90 triangle legs are equal to each other and the hypotenuse measures sqr root of 2 times more than the legs.

The hypotenuse measure 2 times sqr root of 14 so divide by sqr root of 2 to find x and y.

\frac{2 \sqrt{14} }{1}  \times   \frac{1}{ \sqrt{2 } }  =  \frac{ \sqrt{56} }{ \sqrt{2} }  =  \sqrt{28}  = 2 \sqrt{7}

Since x and y are equal, they both measure

2 \sqrt{7}
