$8.28 eight dollars and 28 cents
Answer:
g = 14
Step-by-step explanation:
Given that f varies directly as g and inversely as h then the equation relating them is
f = ← k is the constant of variation
To find k use the condition f = - 12 when h = 4 and g = - 3, that is
- 12 = ( multiply both sides by 4 )
- 48 = - 3k ( divide both sides by - 3 )
16 = k
f = ← equation of variation
When f = 28 and h = 8 , then
28 = = 2g ( divide both sides by 2 )
g = 14
So putting in eqn ;
75x+350 = 100x + 200
25x= 150
x = 6 hrs
A) so the answer is 6 hours !
I can't get the another one , please explain what the question says !! I can not read it properly !!
Answer:
central angle = 360/24 = 15°
arc length = 15/360 * 2π * 15 = 1.25π = 3.93 feet.
Area of a sector = 15/360 * π * (15)^2 = 9.375π = 29.45 square feet
Hope This Helps! Have A Nice Day!!
Answer:
width= x-7
Step-by-step explanation:
l= 8x
Area = l*b
b= 8x^2-56x/8x
b= 8x(x-7)/8x
b= x-7
