The correct answer is 2/5
Answer:
16 crates
Step-by-step explanation:
-This is a division problem.
-Let x be the number of crates that will fit in to the box car.
-To solve x, we divide the volume of the boxcar by the volume of one crate:

Hence, 16 crates will fit in the boxcar.
Salary = $ 30,000
10% of salary =

= $ 3,000
Hence, 10% increase in the salary
= 30,000 + 3,000 = $ 33,000
Thus, the answer is $ 33,000.
Answer:
Step-by-step explanation:
Here's how you solve this problem:
1. Solve for the slope in between the two points using (y2-y1)/(x2-x1)
For this problem that would be: (5-11)/(4+2), so the slope would be -1
2. Put that slope in a slope-intercept form equation and solve for the y-intercept.
Slope-Intercept Form: y=mx+b
y=-x+b
To solve for the y-intercept, use one of the coordinate pairs and input x and y.
11=-(-2)+b
9=b
3. Put that y-intercept back in the equation: y=-x+9
Answer: 48 gallons
Step-by-step explanation:
Given: Previous rate of dispensing water= 9 gallons per min
If Reyna use 8 min showerhead then
Total amount of water dispensed=
After Reyna changed the showerhead to energy saving with equation
y=3x, where y is the amount of water dispensed as a function of the number of x minutes for the new showerhead.
When we put x=8 minutes, we get total amount of water dispensed=
Water saved by Reyna=72-24=48 gallons
