1,743 rounded to the nearest ten is 1,740.
Answer:
x=9
Step-by-step explanation:
Use the intersecting chord theorem:
RE*ET = UE*ES
Substitute values
21 (2x+2) = 30 (x+5)
Expand:
42x+42 = 30x + 150
transpose and simplify
42x-30x = 150 - 42
12x = 108
x = 9
9514 1404 393
Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²
It's the last one. 15/2 is 7.5.
Therefore you must do the same to the 9. Divide 9 by 7.5 To give you 1.2 and that's your answer.
Answer:
Step-by-step explanation:
Let
x -----> the number of annual visitors pass sold
we know that
To find out the number of annual visitor passes sold, divide the total amount raised by the cost of a pass.
so
The linear equation that represent this problem is
Solve for x
Divide by 12.50 both sides
