Answer:
D. R(x)=850x+9600
Step-by-step explanation:
Use the given information as points on a line, and find the slope.
The two given points are (10, 18,100) and (20, 26,600).
slope = (difference in y)/(difference in x)
slope = (26,600 - 18,100)/(20 - 10)
slope = 8,500/10
slope = 850
Only choice D. has a slope of 850.
Answer: D. R(x)=850x+9600

Answer:
a. 3.6
b. 42.5%
Step-by-step explanation:
a. 180/100 = 1.8
1.8 times 2 (since it's 2%) gives us 3.6
B. 17/40 is 42.5
Given:
Length of the cuboid tank = 4 m
Breadth = 2.5 m
Height = 2.4 m
One third of the tank is filled with water.
1 cubic meter = 1000 liters.
To find:
The quantity of the water in the tank.
Solution:
Volume of a cuboid is:
Where, l is length, b is breadth and h is the height.
The volume of the tank is :
Volume of tank is 24 cubic meter.
One third of the tank is filled with water. So, the volume of the water is
The volume of water is 8 cubic meters.
We have,
1 cubic meter = 1000 liters.
8 cubic meter = 8000 liters.
Therefore, the quantity of the water in the tank is 8000 liters.
Answer:
1. 4
2. 9
3. <
Step-by-step explanation:
The ratio 4 to 5 means that the left model should have 4 segments shaded (out of 5 given).
The ratio 9 to 10 means that the right model should have 9 segments shaded (out of 10 given).
Compare the shaded regions. If you draw the horizontal line in the left model. then there will be 8 segments shaded (out of 10), this means the ratio 4 : 5 is less than the ratio 9 : 10.
