Answer:
20 feet
Step-by-step explanation:
Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
We solve this using proportion of
Height/ Shadow
= 5/8 = x/32
Cross Multiply
8x = 5 × 32
x = 5 × 32/8
x = 20 feet
The height of the tree is 20 feet
Answer:
<h2>$108.59 </h2>
Step-by-step explanation:
The dime which is worth 0.10 U.S. dollar, is a ten-cent coin, one-tenth of a United States dollar
the value is 0.1
Now in rounding up of numbers the dime is located one decimal place away i.e 0.5 in the number given in the problem statement
to round up to the nearest dime we have to consider the next number to the dime if this number is greater than 5 we will round up if it is less than five we can not perform any rounding up operation
hence the greatest amount of money is
since the number next to 5 is 9 and 9 is greater than 5 we will round up from 5 to 6
This makes 108.59 the greatest amount of money that rounds to $108.60
To ease the understanding, let's write it in degrees and not in Radian:
Formula of conversion: Degree°/180 = Radian/π
Convert 7π/4 in degrees: = (7x180)/4 = 315°
This angle is in the IV th Quadrant of the UNIT circle. So you can write 315° or - 45° .
sin(7π/4) = sin(315°) = sin( - 45°) = - sin(45°) = - (√2)/2
