Answer:
Resultant force = 70.71067811865 pounds
Step-by-step explanation:
Pythagoras theorem is used to calculate the resultant force since the angles between two wires is 90⁰
Resultant force² = 50² + 50² = 5000
Resultant force = (5000)¹/² = 70.71067811865 pounds
The area of a circle can be found using:
pi x r^2 (where r is the radius)
If the area of the circle is 255pi, then:
pi x r^2 = 255pi
Now we need to make r the subject:
r^2 = 255 (cancel the pi on both sides)
r = square root of 255
r = 15.96871942
Answer: 15.96871942 feet
Hope the answer helps :)
Answer:
A
Step-by-step explanation:
The formula for the volume of pyramid is,
Here, B is base area and height of pyramid.
The volume expression for group 4 is,
Here, expression,
represents the base area and 9 represent the height of pyramid.
So height of the pyramid created by group 4 is 9.
Answer: 9
Answer:
x = -5
Step-by-step explanation:
Get x by itself on the left side. To do that, subtract the 7. Do to both sides. This makes x = -5
