448,261 rounded to the nearest hundred thousand is 500,000
As we can see from the angles given, one is 90 degrees, the triangle should be a right triangle. We are given the two angles and one side which would represent the hypotenuse or the longest side. The area of a triangle is calculated from one half the product of its base and its height. From the given values, we need to calculate for the height and base. We do as follows:
sin 75 = height / √3
height = 1.67
cos 75 = base / √3
base = 0.45
Area = bh/2
Area = (0.45) (1.67) / 2
Area = 0.37 square units
Therefore, the area of the triangle is about 0.37 square units.
Answer: No solution
Step-by-step explanation:
2m+4p=22
6m+12p=66
First, to choose one variable to simplified, I choose to find 1st equations in m form.
2m+4p=22
2m=22-4p [Subtract 4p from both side]
m=22/2 - 4/2p [Divide 2 on both side to find m]
m= 11 - 2p
6m+12p=66
6(11-2p)+12p=66 [Plug in the 11-2p in to m,according to the 1st equation]
66-12p+12p=66
The -12p has cancel with 12p, so it means that there is no solution
Answer: 376.8m
Step-by-step explanation:
Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14, h is the height= 7m and r is radius= 5m
rh = 5m x 7m = 35m while
r^2 = 5m x 5m = 25m
Slot the values into the formula:
V = 2 x 3.14 ( 35) + 2 x 3.14 (25)
V= (6.28 x 35) + (6.28 x 25)
= 219.8 + 157
V= 376.8m
I hope this helps.
