package has a better price bar 10-pack of 2.1 ounce bars cost 15.3712- pack of 1.4 ounce bars cost 15.35
cestrela7 [59]
Hmm... well, the 10-pack of 2.1 ounce bars cost $15.37: 

So that means the price per bar is: 15.37/10 = $1.537
The price per ounce would be: 15.37/(10×2.1) = $0.73

For the 12-pack of 1.4 ounce bars that cost $15.35: 

The price per bar is: 15.35/12 = $1.28
The price per ounce is: 15.35/(12×1.4) = $0.91

In other words, the 12-pack has the better price per bar. 

Although, the 10-pack has the better price per ounce.

What is the value of x in the triangle?<br><br> Round your final answer to the<br> nearest hundredth
lara [203]

Given:

In a right angle triangle,

Hypotenuse = 25 cm

Base = x

Angle between base and hypotenuse = 18 degrees.

To find:

The value of x.

Solution:

In a right angle triangle,

\cos \theta =\dfrac{Base}{Hypotenuse}

In the given right triangle,

\cos (18^\circ) =\dfrac{x}{25}

\cos (18^\circ) \times 25=x

0.9510565 \times 25=x

23.7764125=x

Round the answer to the nearest hundredth (two decimal).

x=23.78

Therefore, the value of x is about 23.78 cm.
