Mika is wrong
Step-by-step explanation:
The LCM of 6 and 9 is 18
ANSWER:
a) y = 15x + 75
b) 50 weeks
EXPLANATION:
P A R T A
2 weeks, 105 dollars --> (2, 105)
5 weeks, 150 dollars --> (5, 150)
<u />
<u>if we use slope intercept form (y=mx+b), we must:</u>
1) find the slope
y2 - y1 -->> 150 - 105 = 45
x2 - x1 -->> 5 - 2 = 3
45/3 = 15
2) find the y intercept
y = 15x + b -->> 150 = 15 (5) + b -->> 150 = 75 + b -->> 75 = b
--------------------------------------------------------------------------------------------
P A R T B
y = 15x + 75 (substitute the y with 825 because that is the goal)
825 = 15x + 75 (solve normally)
750 = 15x
50 = x
Answer:
S = √(3V/H)
Step-by-step explanation:
The opposite operation of squaring is <em>taking the square root</em>.
_____
In the more general sense, the inverse operation for raising to a power is raising to the reciprocal of that power. We know that ...
(a^b)^c = a^(bc)
When we want bc=1, we must have c=1/b.
We know that the denominator of a fractional power is the index of the corresponding root:
For n=2, we don't usually write the index in the root symbol:
In the case of this problem, ...

950
<h3>
Step-by-step explanation:</h3>
V = h··r²
10 × 3.14 = 31.4
31.4 × 5.5² = 949.85
949.85, rounded equals 950
