Answer:
Area = 152ft²
Step-by-step explanation:
Simpifly:
A = 13(13-6) + 9(13-6)
A = 13(7) + 9(7)
A = 22(7)
A = 22(7)
A = 20(7)+2(7)
A = 140 + 14
A = 152
Answer:
855
Step-by-step explanation:
90x9.5=855
Answer:
x = 4
Step-by-step explanation:
12x + 5 = 4x + 37, first subtract both sides by 5 and subtract both sides by 4x
8x = 32, next divide 8 from both sides
x = 4
Let t and f be the number to two and four seat tables respectively.
t+f=22, solve for t
t=22-f, then we are told that capacity must be less than or equal to 72 people.
2t+4f≤72, using t found above in this equation we get:
2(22-f)+4f≤72 perform indicated multiplication on left side
44-2f+4f≤72 combine like terms on left side
44+2f≤72 subtract 44 from both sides
2f≤28 divide both sides by 2
f≤14 Since f=integer
f=14, and since t=22-f
t=8
So they should purchase 14 four seat tables and 8 two seat tables.
Answer: 708017151.707 m^3
Step-by-step explanation:
Volume of a sphere has the equation of
V=4/3(pi)r*r*r=4/3(pi)r^3
r=553 m
4/3(pi)553*553*553=4/3(pi)553^3=4/3(pi)169112377
=676449508/3(pi)=225483169.333(pi)=708017151.707 m^3
Where pi=3.14
