The statements that apply to the ratio of rice and water are:
- The ratio of rice to water is 1 to 2.5
- The ratio of water to rice is 2.5 to 1
<h3>Ratios</h3>
Ratios are used to compare quantities of different measurements
The entries on the table are given as:
<u>Rice Water</u>
2 5
3 7.5
5 12.5
8 20
<h3>The ratios of both quantities</h3>
The ratio (r) of rice and water is then calculated as:

Pick any corresponding table entry.
So, we have:

Divide

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1

Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!
Answer:D) 1 hr
Step-by-step explanation:
Given
Pump A and B can fill tank in 
Pump A and C can fill tank in 
Pump B and C can fill tank in 
Let A be the total hr taken A therefore rate of 
Let B be the total hr taken B therefore rate of 
Let C be the total hr taken C therefore rate of 
-----1
-----2
-----3
Adding 1,2 & 3



thus time taken by A,B and C combined is 1 hr
