The height of a semisphere is equal a radius of this hemisphere.
But... if we can talk about the height of the hemisphere ;)
R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
Your question is not complete but I guess you want to know the total price to be paid. This will be:
= $145 + (5.5% × $145)
= $145 + (0.055 × $145)
= $145 + $7.975
= $152.975
Since the numerical coefficient of the first term is only 1, we determine the number that needs to be added to both sides of the equation by squaring half of the second term. That is,
third term = (15/2)² = 56.25
Thus, the missing terms are,
x² + 15x + 56.25 = 49 + 56.25
equal to,
x² + 15x + 56.25 = 105.25
The area of the polygon will be given by:
A=n(1/2*base*height)
where:
n=number of sides
thus
h=8
thus the base will be:
tan x=[opposite]/[adjacent]
tan 60=8/b
b=4.62
base=9.24
thus the area of the polygon will be:
A=6[1/2×9.24×8]
A=221.76 sq. units
Answer:
x=200
Step-by-step explanation:
4x-x=600
3x=600
divide by 3
x=200
to check your work:
4(200)-200=600
800-200=600
