ANSWER: $65.63
$50 divided by 4 hours = $12.50 per hour
1/4 can also be written as the fraction 0.25
So 5 1/4 hours is the same as 5.25 hours
$12.50 per hour x 5.25 hours = $65.625 rounded to the nearest cent = $65.63
Answer:
The three numbers are : 9, 9 and 18
Step-by-step explanation:
Since the mean is 12 the sum of the three numbers must be 36. This is because:
(let the three numbers be x y and z)
(x+y+z)/3=12
(x+y+z)=12*3
(x+y+z)=36
And since the mode is 9 two of the numbers must be 9.
So to find the third number;
9+9+z=36
z=36-18
z=18
Answer:
Step-by-step explanation:
t/6 is the same as (1/6)t
-5 - 1/6t ≥ -9......add 5 to both sides
-1/6t ≥ -9 + 5
-1/6t ≥ - 4....u can either divide both sides by -1/6, or u can multiply both sides by -6....either way, u have to switch the sign because when dividing/multiplying by a negative requires that. I am multiplying both sides by -6, cancelling the -1/6 on the left
t ≤ -4 * -6
t ≤ 24 <=======
Well for a double roll you will the sum of 20
B because you go up 1 and three to the left which makes it (1,-3)
