Answer:
Martin family: 20 hours
Lewis family: 35 hours
Step-by-step explanation:
Let's say that the Lewis family sprinklers were out for L hours and the Martin family's sprinklers were out for M hours. We know that for each hour that the Lewis family sprinkler was on, 30L of water was put out. We can thus write the Lewis family sprinkler water output as 30L per each hour of L = 30 * L. Similarly, the Martin family sprinkler water output = 15 * M .
We know that the total hours for the sprinklers is 55, so L + M = 55. The total water output for the sprinklers is the sum of the sprinkler outputs, so 30 * L + 15 * M = 1350
L + M = 55
30 * L + 15 * M = 1350
One way to solve this would be to solve for L in the first equation and substitute that into the second
subtract M from both sides in the second equation
55 - M = L
30 * (55-M) + 15 * M = 1350
30 * 55 - 30 * M + 15 * M = 1350
1650 - 15M = 1350
subtract 1650 from both sides to isolate the M and its coefficient
-15M = -300
divide both sides by -15 to isolate M
M = 20
L = 55-20 = 35
Answer:
32
Step-by-step explanation:
16,000 = (2^7)(5^3)
So, the number of positive divisors of 16,000 = (7+1)(3+1)
= (8)(4)
Answer:
C
The integer with the greatest value is the one that is farthest to the right hand side of the number line
Step-by-step explanation:
The number line is constructed in a way such that we have a center point of zero with positive values to the right of the number line and negative values to the left of the number line.
Moving deeper right, we have an increase in positivity, with the more positive values rightwards, indicating an increase in the numbers to the right
Moving to the left, we have an increase in negativity, but a decrease in value. The negative numbers closer to zero are more positive and command higher values than the values which are farther from zero.
What these indicates is that the more rightward a number, the greater its value
