Answer: D $10.84
Step-by-step explanation:
If the box is a cube and paper is needed to wrap it, then we need to find the surface area of the box then multiply it buy the cost of the wrapping paper.
The surface area of a cube uses the formula 6a^2 where a is any side length.
We know that the box has a side length of 8.5 inches.
SA = 6*8.5^2
SA= 433.5
Now multiply the surface area by the money.
433.5 * 0.025 = 10.8375
Round 10.8375 to dollars and cents as it is required.
10.8375 = 10.84
Which means it will cost $10.84 to wrap the box.
5/7*1/2=
D. 5/14
multiplying fractions is simpler than it looks, just multiply straight across
Answer:
Ultraviolet (UV) radiation.
Step-by-step explanation:
Mutagen is part of genetics, it is chemical or physical agent which are present in atmosphere and causes changes or mutation in the genetic materials i.e. in DNA (these changes can be permanent as well). Example of mutagen are radioactive substances, ultraviolet radiation, etc.
UV radiation is an electromagnetic radiation which is present in sunlight. It is a strong mutagen which is when absorbed by DNA can cause extreme damage, for example, uncontrolled division of skin cell can cause skin cancer, that's the reason why UV radiation is the most common mutagen to which we are exposed to when we are outside in the sunlight.
First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.
