2(10+5)−5
=(2)(15)−5
=30−5
=25
C is the answer.
Answer:
150m by 300 m
Step-by-step explanation:
150×300=45000
all sides add up to 900m
150+150+300+300
Answer:
yes
Step-by-step explanation:
answer above
The magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively
The formula for calculating the resultant vector is expressed as:
Given the following distances:
u = -5√3 feet (west direction)
v = 5 feet
Substitute the given values into the formula above;
The magnitude of the resultant vector is 10feet
Get the direction:
Since tan is negative in the second quadrant, hence;
Hence the magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively.

Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac (a, b, and c are the lengths of the 3 sides)
In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.
The area of the top and bottom (side lengths a and c) = a*c. Since there are two of them, you get 2ac. The front and back have side lengths of b and c. The area of one of them is b*c, and there are two of them, so the surface area of those two is 2bc. The left and right side have side lengths of a and b, so the surface area of one of them is a*b. Again, there are two of them, so their combined surface area is 2ab.
