Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : 
Where l is length, w is width, and h is height
Plugging in the new values we get:

The surface area of the enlarged prism = 376 cm^2
It is given in the question that
After being discounted 40%, a weather radio sells for $35.97.
It means the weather radio sells at a 60% of original price.
Let the original price be $x.
Therefore according to the question,

Therefore the original price of the weather radio is $59.95.
Answer:
<h3>
f(4) = 14</h3>
Step-by-step explanation:
f(n) = n + 10
f(4) = 4 + 10 = 14
(a) m<IJK = 90 since segment IK is a diameter
(b) KI = 10 since since LM = KM = KI = 5. The 3 segments are radii.
(c) EP * PL = OP * PF; EP = 2
(d) m<OFH = 178/2 = 89; inscribed angle is half measure of intercepted arc
